Objective: Healthcare providers of all disciplines are greatly affected by the opioid epidemic. In order to reduce the misuse of opioids in dentistry, we must understand its role in our profession. The aim of this study was to compare the opioid prescribing habits for the management of dental pain by periodontists, endodontists, and oral surgeons in the United States. The study investigated the factors associated with the opioid prescription practices of these dental specialists and identified the proportion of opioid prescriptions for each type of dental procedure provided. Methods: A 30-question anonymous survey using Qualtrics software was distributed electronically to periodontists, endodontists, and oral surgeons in the United States who had their email registered with the American Academy of Periodontology, American Association of Endodontists, and Accredited Advanced Education Programs in Oral Surgery member directory as of March 2020. The survey included questions about prescribing tendencies for specific procedures, rationale questions for choosing to prescribe or not to prescribe opioids, and demographic information. Results were analyzed using McNemar tests. Results: Emails were sent out to 4,528 periodontists, 3,962 endodontists, and 100 oral surgeons. A total of 574 responses from periodontists, 523 from endodontists, and 30 from oral surgeons were collected. Periodontists were significantly less likely to report prescribing opioids for less-invasive surgeries, such as extractions and crown lengthening, and more likely to prescribe for more complex procedures, such as ridge augmentation (p

Aims This study thus aimed to review and analyze liability lawsuits resulting from implant surgery-related inferior alveolar nerve (IAN) injury over a twenty-year period in France. Materials and Methods A retrospective descriptive study was performed to analyze judicial decisions pertaining to IAN injury from a legal database between 2000 and 2020. Inclusion criteria comprised all closed malpractice cases that involved an oral and maxillofacial surgeon or a dentist who performed a mandibular implant surgery resulting in IAN injury. The following data were recorded: judicial decision reference (including jurisdiction and date of final court ruling), timing between the incident and final court ruling, number of involved practitioners, patient's age and gender, practitioner's age and gender, implant type, number of implants, location of iatrogenic implant(s), allegation of IAN injury, alleged cause of injury, justification(s) for conviction, compensation amount and legal costs. Results Twelve judicial decisions from high civil courts relating to ten closed cases of liability lawsuits were included and analyzed. All of involved practitioners were dentists or oral surgeons, working in the private sector. Eventually, 85% of them were convicted. Mean indemnification was 17,340€ and highest indemnification was 42,828€ (inflation-adjusted in 2020 euros). Mean interval between the incident and final ruling was 87,1 ± 34,2 months. Conclusions Permanent nerve injury following dental implant placement can result in legal action. In the event of lawsuit, the risk of being convicted is high. Practitioners performing oral implantology procedures should practice effective risk management to avoid time-consuming unwanted litigations and administrative proceedings.

Background The authors undertook a prospective study to determine whether kidney transplant recipients had an increased risk of developing complications, such as local acute infection, alveolitis, increased bleeding, pain, and delayed healing, after tooth extraction. Methods The authors selected patients who underwent kidney transplants more than 6 months ago (study group) and patients who had not (control group) older than 18 years who needed to undergo extraction of erupted teeth. The same oral surgeon performed all tooth extractions while the patients were under local anesthesia. Another blind researcher examined the patients 3, 7, and 21 days after tooth extraction. The first end point was occurrence of complications (local acute infection, alveolitis, increased bleeding), and the second end point was socket reepithelialization on day 21. Results Forty-five tooth extractions were performed on 38 study group participants and 61 on 57 control group participants. There was no statistical difference between the groups regarding the incidence of any complication or delayed socket epithelialization. Conclusions The results of this pilot study suggest that there is no difference in postoperative healing after tooth extractions between stable kidney transplant patients and control patients. Practical Implications This is the first prospective study assessing the frequency of postoperative complications after tooth extraction in kidney transplant recipients. This clinical trial was registered at ClinicalTrials.gov . The registration number is NCT02547753.

Lingual artery (LA) aneurysms are particularly rare, and pseudoaneurysms are associated with trauma, infection, and surgical intervention. LA aneurysms can be fatal if not recognised or treated; however, only a few cases of idiopathic LA aneurysms have been reported in the literature, all of which have been described as pseudoaneurysms. To address this knowledge gap in reporting a true LA aneurysm, here, we describe a 55-year-old woman with an idiopathic aneurysm of the lingual artery. The lesion was detected by another department on a computed tomographic angiography of the neck, which was performed as a post-aneurysmectomy evaluation of the right internal carotid artery. The embolisation failed twice, after which we performed an aneurysmectomy of the left atrium. A histopathological examination of the excised aneurysms revealed fibromuscular dysplasia (FMD). Thus, we believe that FMD may be a cause of external LA aneurysms. Our findings will be relevant for oral surgeons and physicians who may consider FMD as a differential diagnosis when treating multiple LA aneurysms.

Background The dentist-patient relationship is delicate. Engaging the patient in the dental treatment planning especially for lengthy procedures as dental implants improves the relation as well as treatment outcomes including patient satisfaction. We aimed at evaluating the importance of Shared Decision making (SDM) and level of satisfaction among dental implant patients by employing SDM and satisfaction scores. Materials & Methods The present cross-sectional study was pursued between April 2019 to September 2019, among dental implant patients (n = 144) who have completed their prosthetic part of implant treatment with at least 3 months of post-restoration evaluation. Demographic and implant data were collected from electronic filing system (Salud) as well as measurement of SDM score. Data were analyzed using SPSS 24.0 version statistical software. Results The mean satisfaction score was higher for implant placement with Periodontists (31.9%). However, among surgical specialist the mean satisfaction score was found to be higher for oral surgeons who had 1–5 years of experience (46.5%). Patients reported that their decision making was greatly influenced by the treating dentist. A statistical significance was found where (64.6%) of Implant patients would like to undergo the procedure again (p Conclusion Shared decision-making and patient satisfaction enables the treatment delivery to be more effective and ethical, in addition to being patient-centered care.

Dental implant placement is widely used method of dentition restoration, and if necessary, is performed with subantral augmentation of bone tissue and can be associated with an increased risk of complications in cases of mucosa alterations. To the disease and patency of the ostiomeatal complex and to minimize the possible risks is the key task when preparing patients with chronic rhinosinusitis and nasal polyps for sinus lifting. The aim of the study is to investigate the effect of shaver polipectomy method in chronic rhinosinusitis and nasal polyps on the outcomes of sinus lifting and the frequency rate of complications. Materials and methods. The study was based on data obtained from 72 patients having chronic rhinosinusitis and nasal polyps, who underwent endoscopic functional sinus surgery according to the principles of sparing effect on the periosteum in the alveolar bay (periosteum-preserving technology). The patients were divided into two groups: I group included 35 patients subjected to shaver polypectomy; II group consisted of 37 individuals operated on by standard conventional method. Results. The average total Lund-Mackay (LM) score before endoscopic rhinosurgery in I group was 14.57±0.52 scores, and 13.32±0.6 scores in the II group. It went down to 4.26±0.38 in I group and to 4.61±0.39 in II group (p

Retrobulbar hemorrhage (RBH) refers to hemorrhage within the bony orbital cavity and most commonly results from periorbital surgery or trauma. RBH following tooth extraction is a rare occurrence. Patients with RBH will endorse symptoms of periorbital pain, double vision, or vision loss, and present with evidence of proptosis, chemosis, or subconjunctival hemorrhage. Irreversible vision loss may occur if orbital compartment syndrome (OCS) results in the setting of RBH and is not expediently treated. Herein we present a case of a 72-year-old female who developed a RBH and OCS immediately after routine molar tooth extraction. Emergent treatment by the oral surgeon with a lateral canthotomy and inferior cantholysis led to full visual recovery. Dentists and oral surgeons should be aware of this potential rare vision-threatening complication of atraumatic tooth extraction and educated on the technique of decompressive lateral canthotomy and cantholysis.

Background Surgical difficulty assessment in the extraction of impacted mandibular third molars is a constant challenge for oral surgeons. Aim The first aim was to apply Maglione's new classification on patients that needed surgical extraction of impacted mandibular third molars, and the second aim was to study the correlation of the classification classes with the occurrence of postoperative neurosensory disorders. Materials & methods The present prospective clinical trial pilot study was conducted on patients attending oral and maxillofacial surgery clinics from February 2017 until January 2018 for the surgical extraction of impacted lower third molars. Results Fifty-one out of sixty-nine patients made the surgical removal of one impacted mandibular third molar. The most common subclass was 1B (24.6%), followed by subclass 3B (23.2%). Subclass 3A and 4B showed an equal distribution of (11.6%) each, and then subclass 2B (10%). The most significant subclass was 4B with (5.9%) neurosensory disturbance. None of the patients had a permanent disturbance. Conclusion Maglione's classification offers unique detailed description of the buccolingual relationship of MTM with IAC that could be used as a future reliable radiographic guide to reduce the risk of post-operative neurosensory disturbances after MTM surgical removal.

Objective The aim of this study was to analyze patients with thrombophilia who underwent oral and/or maxillofacial surgery at our center. Study Design We performed a retrospective analysis of patients with hereditary or acquired thrombophilia who had undergone oral/maxillofacial surgery between January 1, 2000 and December 31, 2019. Data regarding demographic and patient characteristics, surgical treatment modalities, antithrombotic therapies, and complications were analyzed. Results A total of 76 eligible patients (26 male, 50 female) were included in this study, with a mean follow-up period of 3.8 months (range, 0-51 months). The mean age at time of surgery was 44.7 ± 19.4 years. Seven different hereditary and acquired thrombophilia were identified: factor V Leiden (n = 31; 40.8%), prothrombin G20210A mutation (n = 5; 6.6%), protein C deficiency (n = 4; 5.3%), protein S deficiency (n = 11; 14.5%), antiphospholipid syndrome (n = 10; 13.2%), hyperhomocysteinemia (n = 8; 10.5%), and elevated factor VIII (n = 2; 2.6%). Complications occurred in 9 patients (11.8%) and included postoperative infections (n = 6; 7.9%) and postoperative bleeding (n = 3; 3.9%). Conclusion Our data suggest that oral and/or maxillofacial surgery in patients with a confirmed diagnosis of thrombophilia is not associated with a burden of thrombosis or high complication rates. Furthermore, we formulated a guideline for preoperative antithrombotic therapy for patients with thrombophilia undergoing oral and/or maxillofacial surgery.

Implant placement necessitates an interdisciplinary approach in which a team of dental implant specialists, including an oral surgeon, prosthodontist, periodontist, and oral radiologist, collaborate on the design, execution, and maintenance of the implants to provide the best possible result. According to the data, the vast majority of the participating dentists provide implant-supported restorations to their patients on a regular basis. Surprisingly, the percentage of dentists who plan implant placement and employ backward planning methods was significantly lower. This finding implies that dentists do not always follow the current scientific consensus that the placement of an implant should be based on prosthetic principles.

Background Effective management of Missing lateral incisor has remained a challenge for the clinicians. A multi-disciplinary approach involving orthodontist, restorative dental specialist, pediatric dental specialist, periodontist, oral surgeon and general dentist has proved ideal. Our aim is to review the ultimate esthetic success, and long term survival results between the orthodontic and restorative management of missing lateral incisor. Materials and methods Following the PRISMA guidelines, a systematic review of the published articles pertaining to the topic of interest was done. Searches were carried out in four different databases since February 2021 to April 2021. Results A total of 580 references were found from searches conducted in PubMed, Scopus, Cochrane and Web of Science, and 19 articles were selected and analyzed fully, after screening the title and abstract, 6 articles were included for the study. Conclusion An essential orthodontic space closure in combination with modern aesthetic prosthetic tooth replacement techniques has been reported to achieve greater success.

Purpose: In adults, correction of such a jaw base relation is done by bilateral sagittal split osteotomy and mandibular advancement which often causes change in the cervicomental angle that might not be within the acceptable and aesthetic range. The objective of this systematic review was to evaluate the changes observed in cervicomental angle after mandibular advancement surgery. Data Sources: Based on the available data, we conducted an electronic database PubMed search, based on the search of published data from 1994 to 2017, six strategies were designed using two keywords, and four articles were shortlisted for systematic review. Study Eligibility Criteria: Studies that provide information on cervicomental angle changes after mandibular advancement surgery, published from 1994 to 2017. Results: The search yielded 168 articles, of which four were included based on the selection criteria. These articles described that the cervicomental angle observed after mandibular advancement surgery falls between 95° and 125°. Conclusion: Cervicomental angle decreases as the mandible is advanced to correct the jaw base Class II relation to Class I. Acceptable range is found to be between 95° and 125°. Implications: An esthetic look is the desire of every patient that reports to the clinics for an orthodontic correction. Surgical correction is an integral part of the treatment. While advancing the mandible, change is observed in the cervicomental angle. Knowing the acceptable range of this angle will help the orthodontist and the oral surgeon to plan the advancement accordingly.

Purpose There is inconsistency in clinical grading of peripheral trigeminal nerve (TN5) injuries that impact patient care. The study goal is to assess the current status of evaluation and classification of TN5 injuries by oral and maxillofacial surgeons (OMSs). Patients and Methods A cross-sectional study design used an electronic survey to 100 selected OMSs to determine their clinical TN5 injury practice, including neurosensory testing, confidence level with current protocols, and evaluation and treatment of a hypothetical TN5 injury case. The target sample was enhanced to reduce type 2 error, assuming prior experience in the diagnosis and management of TN5 injuries. Results The sample was composed of 90 respondents. Nerve injury classification systems used by OMSs include Seddon (44%), Sunderland (70%), and Medical Research Council Scale (31%). Neurosensory testing protocols varied considerably among survey respondents. A sample case for Medical Research Council Scale grading produced inconsistent and inaccurate results. There was no consensus on TN5 injury management, and recommendations for timely nerve repair varied from 1 month to up to 1 year after injury. Half of the respondents stated that OMSs are not adequately prepared to assess inferior alveolar/lingual nerve injuries, and most oral-maxillofacial surgery respondents evaluate fewer than 10 TN5 injuries each year. Most OMSs (92%) have had a temporary inferior alveolar/lingual nerve injury, while 54% have had a permanent injury; of which, 21% required microsurgical repair. The majority of OMSs (74%) believed that a uniform TN5 injury classification system is needed. Conclusions Within the oral-maxillofacial surgery target group experienced in evaluation of TN5 injuries, respondents do not feel confident in the assessment of these injuries. There is inconsistency in evaluation methods, and there is agreement that a unified classification system is needed for more efficient patient evaluation and reporting of outcomes in the literature. The Medical Research Council Scale and clinical neurosensory testing is preferred for evaluation of TN5 injuries.

Background: Nasoalveolar molding (NAM) is a presurgical orthopedic procedure, mainly focusing upon the aesthetic outcome of the treatment goal by reducing the number of reconstructive surgeries performed later for the purpose of esthetics. It was reported a very small proportion of pediatric dentists are providing presurgical intervention and the practice of NAM still side stepping among various dental practitioners. Objectives: The study was aimed to assess the knowledge and attitude among various dental specialties regarding NAM procedure in cleft patients. Materials and Methods: A questionnaire-based cross-sectional survey was carried out among 180 dental professionals (pedodontists, orthodontists, prosthodontists, oral surgeons). A total of 180 questionnaires were prepared, out of which 98 were filled through direct personal interview and 82 were circulated via Google forms. Results were analyzed using chi-square test, Mann-Whitney U test, and Kruskal-Wallis test. Results: There was statistically significant difference in the cumulative knowledge scores between specialty with P < .001; 99% of the participants think one should opt for NAM before cleft lip and palate surgery and 39% participants prefer pedodontists to carry out NAM procedure. Conclusion: Dental specialists in India have a positive attitude toward presurgical orthopedics. Majority of them agreed that there is great improvement in the aesthetic outcomes of surgeries after NAM intervention.

Oroantral communication and fistula are commonly seen complications in the field of oral and maxillofacial surgery. Oral surgeons must be familiar with the diagnosis and proper management including multiple soft and hard tissue approaches to this surgical dilemma.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 manifests mainly as respiratory symptoms. Extrapulmonary manifestations have also been detected and several vital organs may sustain irreversible or long-standing damage. These extrapulmonary manifestations can be detected in cardiovascular, hepatic, renal, and hematologic systems. Maxillofacial surgeons may encounter patients who have recovered from COVID-19 but are still suffering long-term morbidities as a result of this incompletely understood infection. Consequently, they have to be aware of the various systemic complications that may be encountered in these patients as they may interfere with their treatment plan or may necessitate certain modifications and precautions.In this report the authors present the long-standing systemic complications of COVID-19 reported so far, and discuss their implications within the context of maxillofacial surgery with regards to the modifications and precautions in the process of treatment planning.Graphical abstract shows the long-term complications of COVID-19 that may complicate maxillofacial surgical procedures.

Burkitt lymphoma (BL) is an aggressive form of non-Hodgkin B-cell lymphoma, with three subtypes: endemic, sporadic, and human immunodeficiency associated subtypes. Endemic BL typically involves the mandible, maxilla, and abdomen, whereas sporadic BL usually presents as an abdominal mass involving the mesenteric lymph nodes or ileocecal region, and jaw involvement is uncommon. In pediatric patients, oral BL commonly presents as facial swelling with an intraoral exophytic mass and is usually accompanied by mobile, displaced, and/or painful teeth. We report sporadic BL initially presented as orofacial manifestations in an 8-year-old boy, and conduct a mini-review. He had left facial and gingival swelling. CT revealed the lesions were located at the left anterior maxilla and the masticator muscle, and PET showed multiple lesions. An incisional biopsy of left anterior maxillary gingiva was performed, and the pathological diagnosis was BL. Oral management has been performed since initial chemotherapy, and tumor remission was achieved by chemotherapy with the B-NHL03 study regimen at our pediatric department. There was no recurrence of the tumor 5 years after chemotherapy. Dentists and oral surgeons should be aware that dental problems including floating teeth and/or alveolar bone resorption might be the first clinical manifestation of BL. Because the success of intensive treatment relies on good supportive care, oral management plays an important role to maintain oral hygiene.

Double teeth refer to two teeth that are totally or partially joined by dentin and maybe their pulps. These developmental anomalies may be the result of either gemination or fusion. This is a case of a 15-year-old Indo-Trinidadian male who presented with the fusion of a mandibular third molar with a distomolar as an incidental finding. The patient had his general dental care provided by a paediatric dentist and was referred to an oral and maxillofacial radiologist, orthodontist, and oral surgeon for consultation. A Cone-beam CT was taken to supplement the plain film periapical and orthopantomogram radiographs. It showed the three-dimensional orientation of the double molar and the extent of joining. This is the first case of fusion of a mandibular third molar to a distomolar being reported in the Caribbean.

Background Treatment of facial fractures in children and adolescents has always been a challenge for oral surgeon. The choice of treatment type must take into account several factors. This systematic review aimed to evaluate closed versus open reduction of facial fractures for pediatric facial fractures. Material and Methods A systematic review of the literature was conducted in three databases (PubMed/MEDLINE, Embase and The Cochrane Library) in accordance with the PRISMA statement. The PICO question was: Conservative treatment is more appropriate than surgical treatment for reducing facial fractures in children and adolescents? The full papers of 41 references were analyzed in detail. Eleven papers were included in this systematic review: one prospective study and ten retrospective studies. All studies evaluated the complication rate. Results A total of 73 (7.68%) of the 950 patients experienced complications. Among these patients, 24 (3.85%) had been treated with conservative treatment and 49 (15.03%) with surgical treatment. The fixed-effects model revealed a lower complication rate with conservative treatment than surgical treatment (P

Objective:The placement of a root-end filling material to seal the end of the root canal is one of the most important procedures in apical surgery. In Turkey, root-end surgeries are most often performed by oral surgeons. This national survey aimed to evaluate and describe the use of root-end filling materials after apical resections among oral surgeons.Materials and Methods:A web-based survey consisting of nine questions was prepared using Google forms, and the link to the survey was sent to the oral surgeons. The questionnaire collected information regarding age, gender, level of education, number of years of practice, type of institution, average frequency of root-end resections performed per month, whether root-end filling material was used after apical resections, type of the root-end filling material used and reasons for not placing a root-end filling material. Data was expressed as percentages and frequency rates. Chi-square test was used to identify associations between the usage patterns and surgeons’ demographics.Results:A total of 155 questionnaires were returned. Most of the oral surgeons surveyed (82.6%) performed root-end resections at a rate of

Referral to an oral surgeon for soft-tissue surgery before, during or after orthodontic treatment is not uncommon. This process may delay treatment and could potentially increase the risk of complications. In addition, seeing multiple specialties in different environments may demotivate paediatric or anxious patients from pursuing orthodontic treatment and could also adversely affect patient compliance and satisfaction. The development of laser technology provides a safe and effective alternative, allowing the orthodontic clinician to perform soft-tissue surgery. To date, there are no laser exposure protocols or UK guidelines regarding the use of laser surgery in orthodontics. This case series reports four clinical cases that demonstrate potential advantages of using a diode laser for the management of soft tissue in the field of orthodontics.

Absztrakt: Bevezetés: Napjainkban egyre növekszik a sikeres szervátültetésen átesett páciensek száma. A transzplantációt követően alkalmazott immunszuppresszív terápiának, a korszerű peri- és posztoperatív ellátásnak köszönhetően a páciensek várható élettartama is jelentősen kitolódott. Ennek következtében a fogorvosi-szájsebészeti ellátás során gyakrabban találkozhatunk ilyen betegekkel, jelen ismereteink szerint azonban jelenleg nem áll rendelkezésre széles körben elterjedt, magyar nyelvű kezelési irányelv. Célkitűzés: A 10 000. magyar szervtranszplantáció apropóján munkacsoportunk célul tűzte ki, hogy az egyre növekvő számú beteget érintő, a fogorvosi-szájsebészeti ellátás során sokszor kihívást jelentő témakörben, a nemzetközi szakirodalmat áttekintve, jó gyakorlatokon és evidenciaalapú ellátási protokollokon nyugvó ajánlást ismertessünk a transzplantált betegek perioperatív fogorvosi-szájsebészeti ellátásáról. Anyag és módszer: A 2010. és 2019. év közötti, angol és magyar nyelvű szakirodalom áttekintését és összehasonlító elemzését végeztük el az említett témakörben. Eredmények: A nemzetközi irodalomban kevés és alacsony evidenciájú vizsgálat áll rendelkezésre. Ezeket áttekintve részletesen bemutatjuk a transzplantációt szükségessé tevő kórképek vonatkozó rizikófaktorait, a transzplantált betegek perioperatív, korai, illetve késői posztoperatív fogorvosi-szájsebészeti teendőit, és kitérünk a szervspecifikus megfontolásokra, valamint az alkalmazott gyógyszeres kezelés lehetséges szájüregi manifesztációira. Következtetés: Az élethosszig alkalmazott gyógyszeres kezelés, a mesterségesen gyengített immunológiai status fokozott figyelmet igényel az egészségügyi személyzettől a betegellátás során. A kezelőorvos és a fogorvos együttműködése nélkülözhetetlen a betegbiztonság fenntartása érdekében. A gyulladásos kórképek fokozott veszélyt jelenthetnek a páciensre, ezért a jó szájhigiéné fenntartása nélkülözhetetlen. A rendszeres fogorvosi kontroll, a korai felismerés és az adekvát terápia elengedhetetlen feltételei a hosszú távú szövődménymentes túlélésnek. Orv Heti. 2020; 161(36): 1506–1513.

Maxillofacial and oral surgeons (MFOS) are trained to manage hard and soft tissue conditions affecting the orofacial region. They, therefore, play an essential role in the health care of cleft lip/palate (CLP) and craniofacial deformities (CFD) patients. The complex and lengthy nature of CLP and CFD management requires collaboration between different disciplines. Consequently, it becomes increasingly important that the academic education available to MFOS provides in-depth knowledge, multidisciplinary participation and adequate clinical exposure provided by field experts. This study aimed to investigate the exposure and knowledge level of MFOS regarding the management of CLP and CFD. A second objective was to obtain an opinion from practising MFOS about the academic educational needs of those working with CLP and CFD. An online survey and telephone interviews (using a structured questionnaire) were used to investigate the level and scope of the MFOS academic education and to determine their academic needs. The questionnaire was completed by 53 (of 121) of practising MFOS on the Medpages health care provider database, 64.8% of whom had more than 10 years of professional experience. Of the respondents, 60% showed a good general knowledge of CLP and CFD. However, 66.5% acknowledged that they had received only limited clinical training and exposure, which prevented them from providing adequate services to CLP/CFD patients. Only 41% of the respondents offered primary and/or only secondary treatment for both CLP and CFD patients, and 53.8% of them had participated in multidisciplinary teams. All the respondents agreed on the need for a dedicated training programme(s) in CLP and CFD management, and the majority recommended a subspecialty training either by degree courses or clinical fellowship and / or certification. This study demonstrates that postgraduate academic training and clinical exposure are limited in the CLP and CFD fields. All the respondents agreed that an educational strategy to meet the needs of MFOS providing CLP and CFD care should be established. Participants suggested that part-time clinical and/or degree courses should be developed.

Lasers are excellent devices that can add significant value to orthodontic practices. Orthodontists can now perform many procedures quickly, efficiently, and bloodlessly in their offices, instead of referring them back to the general practitioner, oral surgeon or periodontist. Many different laser devices are currently on the market, with purchase prices that vary from $5000 to well over $100,000. In order to understand how to use a laser, how a laser works on oral mucosa, and how to maximize use of this device in an orthodontic practice, it is critically important that the dentist understands the basics of laser-tissue interaction and the role a good laser education program plays in selection of the best device for their practices.

Background Oral surgeons are exposed to blood spatter. The authors evaluated the prevalence of and risk factors for blood spatter in facial masks during oral surgery procedures. Methods The authors evaluated facial masks and caps of oral surgeons and assistants for blood spatter using the Kastle-Meyer test after different oral surgery procedures. The authors correlated the presence of blood spatter to the clinician, type of surgery, surgery time, and self-awareness of blood spatter, using χ2 and t tests. Results The authors analyzed a total of 202 samples and detected blood particles in 46% of the samples in both operators and assistants. The authors observed blood contamination in all types of procedures, and in 4% of the cases, the internal part of the visor was also affected. Clinicians were unaware of the presence of blood spatter in 40% of the cases. Conclusions The risk of clinician contamination with blood during tooth extraction and implant placement was 46%. The risk increased with the use of high-speed instruments and longer surgery time. Practical Implications The use of facial protective devices should be mandatory during oral surgery procedures to avoid blood contamination, especially when rotary devices are used. In many cases, imperceptible blood spatter is present.

Lesions arising from odontogenic tissues of the jaws vary from very common to very rare. Some, such as radicular cysts, form a routine part of the diagnostic workload for histopathologists who report specimens from the head and neck, but many other lesions are rarely seen and can cause significant diagnostic difficulty for the non-specialist. These issues are compounded by the vagaries of dental disease (and terminology used by dentists and oral surgeons) and issues in the interpretation of radiographic images, which can be crucial to making a correct diagnosis. In this review article, we will discuss a number of areas of diagnostic difficulty, largely based on the authors experience in receiving tertiary referrals. This will focus on practical advice to help avoid the pitfalls in the diagnosis of odontogenic lesions.

Objective: Most tooth extractions are performed for dental reasons, but there are also nondental and nonmedical reasons for extractions; these include psychological, financial, religious, and cultural reasons as well as simply granting a patient's request. This systematic review was performed to examine the proportion and range of indications associated with tooth removal in context of dental, nondental, and medical reasons. Methods: A search conducted using PubMed, Embase, and APA PsycINFO identified 6038 studies. Three studies (4396 extractions in total) could be included for the risk of bias assessment and qualitative data synthesis. Results: The reported indications for tooth extraction on dental and medical grounds included caries with the proportion of all extractions ranging from 36.0% to 55.3%, periodontitis from 24.8% to 38.1%, trauma from 0.8% to 4.4%, periapical disease from 7.3% to 19.1%, orthodontics from 2.5% to 7.2%, and other reasons from 4.5% to 9.2%. The proportion for patient requests ranged from 3.6% to 5.9%, but specific information regarding the actual reasons for extraction could not be determined. Conclusion: The results suggest that caries and periodontitis are the most common indications for tooth extraction and that studies to reliably estimate the incidence of nondental and nonmedical motivation for extraction are lacking. Given that the final decision on performing or refusing extractions, whether it be based on dental, nondental, or nonmedical reasons, largely rests with the dentist and oral surgeon, detailed guidelines are warranted.

BACKGROUND Due to technology and pharmaceutical science and increasing life expectancy, the patient population is continuously aging. Patients requiring dental extractions often have systemic and/or chronic diseases and are undergoing polypharmacologic therapy. Oral surgeons often interface with patients who perform anticoagulant therapy. The main aim of this study was to clarify what the contraindications and short-/long-term complications may be. METHODS A sample of 298 patients (mean age 58 years) who required multiple surgical dental extractions has been taken in consideration. Patients were divided into groups and subgroups according to the anticoagulant drug therapy. RESULTS Long-term complications represented variable bleeding between groups from 8 hours to 7 days after surgery. The One-Way ANOVA Test was used to compare the results between groups. Patients treated with direct oral anticoagulants showed fewer intraoperative problems, but further studies and further collaboration between doctors, cardiologists and oral dentists/surgeons are certainly needed to manage these patients in a predictable manner. CONCLUSIONS This study showed that using direct oral anticoagulants drugs results in few intraoperative bleeding, less postoperative hemorrhagic complications, and an easier administration of the drugs respect vitamin K antagonists, with mild and manageable complications.

Human body dissection was a ubiquitous practice in the past, to better understand anatomy and to develop medicine. Today, its role could still be important to answer everyday clinical queries and help surgeons. The example of the possible lack of anesthesia during symphysis surgeries can emphasize the usefulness of dissection. The mandibular symphysis usually receives innervation from inferior alveolar nerve terminations, but, in some rare cases, a particular anastomosis involves the lingual nerve and the nerve to the mylohyoid. The anatomical knowledge resulting from body dissections could help oral surgeons to understand the reason why the patient could feel pain during the surgery, and ensure performance of the right lingual nerve block to obtain complete anesthesia. This clinical situation shows the educational role of an ancient, yet still valid, practice, human dissection, and the importance of anatomical studies to improve surgical skills, to provide better treatment for the patient.

This systematic review aims to compare conventional corticotomy with minimally-invasive protocols (MIP). Electronic database, in MEDLINE and CENTRAL, and hand search were performed. Randomized controlled trials (RCTs) and randomized split-mouth designed studies (RSMSs) were selected for inclusion, reporting either the use of a corticotomy procedure or a MIP. The main outcomes were the rate/velocity of tooth movement, type of tooth movement observed, loss of anchorage, periodontal indexes, inflammatory mediators, root resorption, patient's pain experience, impact on the quality of life, and satisfaction. Twenty-two papers were included for the qualitative synthesis, from which ten RCTs and twelve RSMSs. Eighteen of them compared a conventional orthodontic treatment without and with a surgical adjunctive procedure, two with conventional corticotomy and sixteen with a MIP (piezocision, micro-osteoperforations (MOPs) or interseptal bone reduction). Four trials compared a surgical procedure to another one. Corticotomy, piezocision and MOPs are likely to accelerate tooth movement, in decreasing order. Pain is reported to be higher in experimental groups only on the first day after surgery. Patient satisfaction is high after surgical procedures. Loss of anchorage, periodontal indexes, or root resorption occurrence show no differences between groups. Corticotomy stands as the gold-standard procedure for surgically-assisted orthodontics, but piezocision appears as a good compromise solution as well as MOPs, in a lesser extent. MIP are known to accelerate tooth movement only during the first three months.

This study examines the association of patient age, sex, race, ethnicity, Medicaid coverage, and the need for an interpreter in addition to procedure type and dental provider type with receipt of an opioid prescription in dental care settings within a large health system.Materials and Methods: This study was conducted utilizing data from the electronic health record of HealthPartners, a large dental practice embedded within a health care system. The analytic sample consisted of all 169,173 encounters from 90,487 patients undergoing a dental procedure in the baseline period (9/1/2018 to 8/30/2019), prior to implementing a clinical trial to de-implement opioids in dentistry.Results: Opioids were prescribed at 1.9% of all 169,173 encounters and rates varied by patient factors, procedure category, and provider type. Opioid prescriptions were most likely for extraction encounters (25.9%). In a multivariable analysis of 8760 extraction encounters, all patient age groups were more likely than those age 66+ to receive an opioid prescription, particularly those age 18– 25 (OR=6.94). Patients having a complex rather than simple extraction were more likely to receive an opioid prescription (OR=6.31) and those seen by an oral surgeon rather than a general dentist (OR=9.11) were more likely to receive an opioid prescription. Among 108,748 encounters with a diagnostic procedure, opioid prescribing was more likely among male than female patients (OR=1.20), Black patients relative to White (OR=1.69), patients with Medicaid coverage (OR=1.86), and patients seeing an oral surgeon rather than a general dentist (OR=27.81).Conclusion: Opioid prescribing rates vary considerably depending on procedure type. Patterns of associations between patient factors and opioid prescribing also vary considerably across procedure type. To understand which patient groups are more at risk of being prescribed opioids, it is essential to consider the procedures they are receiving.Keywords: dentistry, oral surgical procedures, analgesics, opioid, prescribing, practice patterns

Objectives To query the experience of oral surgeons concerning referral routines and preferences for radiographic imaging modality before surgical removal of mandibular third molars and investigate factors that influence imaging modality preferences. Materials and methods Members of the Swedish Association of Oral and Maxillofacial Surgeons (n = 280) were invited to participate in a web-based digital survey concerning their experiences and use of three imaging modalities in pre-surgical assessment of mandibular third molar removal. The survey comprised multiple-choice questions and four cases depicted in images; respondents reported whether they would supplement the cases with other images and, if so, from which modality. Results The response rate was 64%. Panoramic radiographs were most commonly used in pre-surgical planning (response options: always or often), significant difference between professions (p = 0.039), and considered to facilitate treatment planning (87%), as was CBCT (82%); for 51%, CBCT reduced post-operative complications. Preferred modality for localizing the mandibular canal was fairly evenly distributed and for non-complex case, significant difference between subgroups of OMFS surgeons was found (p = 0.003) as to preference for intraoral radiographs. Conclusions A majority of respondents received a report within 2 weeks of their referral for CBCT and would read the report and view the images before surgery. Image modality preference differed depending on case complexity, with a greater perceived need for CBCT. Profession and practical experience affected choice. Clinical relevance Choice of imaging modality in mandibular third molar assessment is also important from dose delivery and social economy standpoints.

This article illustrates the indications and mechanism of action of core emergency medications as well as emergency medications for intravenous sedation in the oral and maxillofacial surgeon office. The recognition of medical emergencies and comprehensive knowledge of pharmaceutical medical intervention can prevent deterioration in medical emergencies. In addition, this article also reviews common dosages as well as administration techniques that should be regularly reviewed and be fundamental knowledge to the oral surgeon and staff.

Vascular anomalies are subdivided into vascular tumors (hemangiomas) and vascular malformations. They are frequently located in the head, neck, and oral cavity. They are common complaints reported in patients seeking treatment for aesthetic or functional issues. However, recent advances in the diagnosis and management of these lesions are improving treatment strategies. This review provides both basic and up-to-date knowledge on the most common vascular anomalies encountered by practitioners. Due to the wide variability of treatment options which often generates debate, this paper work aims to provide a comprehensive approach of these lesions based upon current concepts and practical clinical experience. Our article is about 4 patients who had consulted for one or several purplish, elevated, well limited and soft lesion. These lesions was not painful, but worrying for patients. Therapies for VAs continue to generate a dilemma for oral surgeons. Several treatment options were reported, including conventional surgery with or without adjunctive preoperative embolization, and drug therapies, such corticosteroids, intralesional injection of corticosteroids and intralesional injections of sclerosing agents. All of these therapeutic approaches carry a high risk of severe side effects such as scars, pain, and bleeding [7]. Nowadays, advances in the use of lasers have allowed doctors an effective treatment with minimal side effects [9]. All our cases described in this article were done by Pr Haitami, using the 980 nm Diode laser, and a complete healing was observed in about 8 months at the most. The laser is therefore a great help in the management of this type of lesion., Highlights • The last classification and clinical aspects of vascular anomalies • Contribution of the laser in the management of angiomas • The use of the 980 nm diode laser to the sclerosis of the venous malformation by intralesional photocoagulation

Fanconi anemia is a rare disease, which is characterized by decreased production of all blood cell types. Fanconi anemia is the most common inherited form of aplastic anemia. Congenital abnormalities of the eyes, ears, and heart, malformed or absent kidney, urogenital system involvement are common. There is a delay in physical development. Intelligence in patients with Fanconi anemia is usually normal. The most serious problems associated with Fanconi anemia include the gradual development of bone marrow disorders. Many patients with Fanconi anemia develop leukemia or myelodysplastic syndrome, as well as other oncological diseases. Oral manifestations in patients with Fanconi anemia can be classified as gingivitis, periodontitis, dental caries, dental anomalies, soft tissue lesions, oral cancer, and lesions of the tongue. Patients with Fanconi anemia have increased predisposition to squamous cell carcinoma of the head and neck and oral cancer. The interdisciplinary team of medical and dental specialists must be included in the medical and dental treatment of patients with Fanconi anemia. For proper dental care of patients with Fanconi anemia, the close cooperation of dental specialists, including orthodontists, pedodontists, prosthetists, oral surgeons, as well as specialists in periodontology and oral diseases, is of particular importance.

3D-printing is part of the daily practice of maxillo-facial surgeons, stomatologists and oral surgeons. To date, no French health center is producing in-house medical devices according to the new European standards. Based on all the evidence-based data available, a group of experts from the French Society of Stomatology, Maxillo-Facial Surgery and Oral Surgery (Societe Francaise de Chirurgie Maxillofaciale, Stomatologie et Chirurgie Orale, SFSCMFCO), provide good practice guidelines for in-house 3D-printing in maxillo-facial surgery, stomatology, and oral surgery. Briefly, technical considerations related to printers and CAD software, which were the main challenges in the last ten years, are now nearly trivial questions. The central current issues when planning the implementation of an in-house 3D-printing platform are economic and regulatory. Successful in-house 3D platforms rely on close collaborations between health professionals and engineers, backed by regulatory and logistic specialists. Several large-scale academic projects across France will soon provide definitive answers to governance and economical questions related to the use of in-house 3D printing.

Patient A 33-year-old man diagnosed with extranodal natural killer cell/T-cell lymphoma, nasal type (ENKTCL-NT) inducing palatal perforation was referred to the perioperative oral care support center of Tohoku University Hospital for dental care to support cancer treatment including chemotherapy and hematopoietic stem cell transplantation (HSCT). Dental review during chemotherapy revealed mucositis suspected to be caused by mucosal trauma from altered jaw function (chewing and speech) due to palatal perforation. Although the patient was already in the cleanroom, an oral appliance as well as conservative care as recommended in oral management guidelines for HSCT were used to prevent worsening of oral mucositis at subsequent HSCT including High-dose chemotherapy and total body irradiation. After HSCT, a prosthodontist fitted a palatal obturator made by a dental technician and an oral surgeon reviewed the necrotic bone and removed the sequestra according to the changes in the palate. This approach involving a multidisciplinary team including a hematologist improved the impaired oral function and minimized oral complications . Discussion ENKTCL-NT and its treatment have a significant impact on patients' oral status. Hence, it is important to provide customized dental care based on previously endorsed guidelines according to the type of disease, treatment requirements, and oral and systemic status. Conclusions This report indicated the importance of dental care with a customized plan before, during, and after HSCT for ENKTCL-NT with multidisciplinary supportive care for cancer patients to improve the impaired oral function and to minimize oral complications.

Extraction of impacted mandibular third molars is one of the most common surgical procedures performed at dental clinics; however effective training models for teaching oral surgery to dental students are limited. This study aimed to use three-dimension (3D) printing technology to develop an effective training model for impacted third molar extraction.The data for the 3D model were digitally processed using high-resolution computed tomography, and two common, but different patterns of impacted third molars were simulated using computer-aided design. Thereafter, the model was printed using the 3D-printing technology, and the efficiency of the 3D-printed model and an animal model (pig mandible) were compared using a five-point Likert scale by 35 oral surgeons in the oral surgery department and 208 students of stomatology in the internship stage.The 3D-printed model consisted of three parts: a non-replaceable part (i.e., the body of the mandible and the teeth from the left first molar to the right first molar) and two replaceable parts (i.e., the part of the ascending ramus of the mandible, as well as the second and third molars). It was covered with a layer of rubber-like material to simulate the gingiva. For the comparison between the 3D-printed and animal models, a total of 205 questionnaires were collected. Both oral surgeons and students agreed that the 3D-printed model was better than the animal model in terms of total value and the anatomy of the bone and teeth, simulating the surgical procedure (p 0.05), while the two models achieved similar results for haptic feedback of the soft tissue (p 0.05).The 3D-printed model is realistic and effective for learning impacted third molar extraction and received positive feedback from students and oral surgeons. This model can significantly improve the pre-clinical skill training of dental students.
