Abstract Background Surgical extraction of impacted third molars (ITM) often leads to postoperative discomfort including pain, swelling, and limited function. Steroids like dexamethasone (DXN) are commonly used in oral surgery to manage pain and inflammation. Various administration routes for DXN exist, including intravenous (IV), perineural (PN), and oral applications, each with its advantages. Previous studies have shown that adding DXN to local anesthetics can prolong anesthesia duration and reduce postoperative sequelae. However, comparative studies on IV and PN applications with inferior alveolar nerve block (IANB) of DXN in ITM surgeries are limited. Methods This controlled, randomized observational study involved patients undergoing Class II position B ITM extraction. Patients were divided into three groups. IANB (1.8 ml of articaine hydrochloride + 1 ml of saline) was performed 1 h after IV-DXN (4 mg/ml DXN) was administered to the IV group. DXN along with IANB (1.8 ml of articaine hydrochloride + 1 ml of 4 mg/ml DXN) was applied to the PN group. Only IANB (1.8 ml of articaine hydrochloride + 1 ml of saline) was applied to the control group. Anesthesia duration was assessed as primary outcomes. Anesthesia duration was evaluated using a vitalometer from the molars. Secondary outcomes included postoperative pain and edema measured on the 1st, 3rd, and 7th days after surgery. Pain was evaluated postoperatively by using a visual analog scale. A p-value

Background: The simple explanation of burnout syndrome is exhaustion from work and work-related factors. It is more common in work that requires face-to-face contact with people, such as dentists. In this study, we researched the burnout levels of dentists working in Turkey and evaluated them according to gender, title, place of work and experience. Methods: Burnout scores were determined by the Copenhagen Burnout Inventory. This questionnaire was delivered to dentists online through various social media applications. We analyzed data via SigmaPlot Software. Results: The answers of a total of 477 dentists were considered valid. We observed that 73,5% of them had high burnout scores. A statistically significant difference was found in the evaluations according to the title and workplace. Experience and gender do not statistically affect burnout scores. Conclusion: It has been observed that dentists working in Turkey are more likely to face burnout syndrome at high levels. It has been predicted that patient burden may be closely related to burnout syndrome.

Introduction: Inappropriately prescribed antibiotics accelerate the formation of antibiotic-resistant bacteria. This circumstance creates a problematic situation in terms of public health. This study aims to measure dentists' antibiotic/prophylaxis knowledge and awareness of antibiotic resistance in Turkey based on two case scenarios. Materials Methods: Dentists in Turkey are invited by open invitation posts on various social media applications for our twelve-question online survey. The scoring was shaped based on answers to measure antibiotic/prophylaxis knowledge. The collected data were statistically analyzed by SPSS Statistics 22. Results: 321 participants answered all questions included in the study. The statistical analyses showed a significant difference in the evaluations according to gender, title, graduation time, and workplace. Conclusion: Inappropriate antibiotic prescription by dentists is common in Turkey. Dentists should receive more undergraduate lessons, and taking reminder antibiotic courses at regular intervals after graduation can contribute to keeping their knowledge up to date.

Background: This study aims to determine the position of impacted maxillary canines on cone beam computed tomography (CBCT) images, to determine the presence of resorption in adjacent teeth, and to investigate the position and type of resorption of impacted canines if resorption is present. Methods: Patients over 14 years of age with maxillary canine teeth who had CBCT images taken for any dental reason were included in the study. Resorption of teeth adjacent to maxillary canines was analyzed according to transversal, vertical, and buccopalatinal positions on the CBCT. The study evaluated 162 maxillary canine teeth on tomography images of 134 patients. Results: Of the affected adjacent teeth, 32.1% of the central incisor, 58.0% of the lateral incisor, and 19.1% of the first premolars showed mild-to-severe resorption. The relationships between transversal position and resorption in the central and lateral incisor, vertical position and resorption in the central incisor and buccopalatinal position and resorption in the first premolars were found to be significant. Maxillary canine teeth can cause mild-to-severe resorption of adjacent teeth, especially lateral incisors. Conclusion: For this reason, we think that a detailed examination with CBCT is essential in the early diagnosis of resorption of adjacent teeth.

Implant surgery in individuals with atrophic maxilla presents challenges, particularly concerning nasal cavity complications such as perforations, implant migration, and airway obstruction. While panoramic radiographs offer diagnostic convenience, their two-dimensional nature limits the evaluation of anatomical structures. Cone beam computed tomography (CBCT) provides a three-dimensional assessment, enhancing surgical planning accuracy and potentially reducing complications. With the aim of understanding the measurement differences between panoramic radiographs and CBCT images, this retrospective study examined CBCT images of patients with severely atrophic maxilla taken between September 2021 and December 2023 at the Ahmet Keleşoğlu Faculty of Dentistry. Virtual implants were placed in various tooth regions using OnDemand3D software. The incidence of nasal cavity perforations and vertical bone height differences between panoramic radiographs and CBCT images were evaluated. For this purpose, vertical bone length measurements in panoramic and CBCT images were compared for the virtual implant placement areas. Statistical analyses, including t-tests and ANOVA, were performed to determine significant differences among quantitative measurements, and a chi square test with Bonferroni corrected z-tests were used for possible associations between ratios. CBCT data from 59 patients, totaling 1888 virtual implants, revealed significant differences in implant depths among tooth regions (F = 9.880, p < 0.001). Canine regions showed higher perforation risks, especially with 12 mm and 14 mm implants. Panoramic radiographs often overestimated vertical bone height in canine and first premolar regions compared to CBCT measurements, which could lead to increased perforation risks. Radiographic evaluations using CBCT prior to implant surgery in atrophic maxilla cases are crucial to prevent nasal cavity complications. Panoramic radiographs may inadequately represent three-dimensional anatomy, underscoring the importance of CBCT for accurate implant placement and surgical planning. Further studies should consider varying implant sizes and brands to generalize findings.

Background: The aim of this study was to evaluate the biocompatibility and effectiveness in terms of osseointegration of dental implants composed of novel injectable bone grafts with and without ostrich eggshell particles and membrane protein in rabbit femur. Methods: Sixteen adult male New Zealand rabbits were used in this study. A bone defect was created in each animal’s right and left femur, and a dental implant was placed adjacent to the defect. Two graft materials were prepared, one containing the membrane protein and the other not. In two groups, the defects were filled with these materials. In the negative control group (NC, (n:8)), the defects were left empty. A commercial product of biphasic calcium sulfate was used as a positive control material (PC, n = 8). The graft groups were defined as the group with the membrane protein (MP+, (n:8)), and without the membrane protein (MP−, n:8). The animals were euthanized at the 12th week after surgery. The samples were investigated using histology, histomorphometry, and micro-computed tomography. Data were statistically analyzed using one-way ANOVA and Tukey’s tests (p = 0.05). Results: Both the PC and MP+ groups had similar newly formed bone areas, and the mean values of these groups were significantly (p < 0.05) higher than those of the MP− and NC groups. The PC group had the highest amount of unresorbed material, while the MP− group had the lowest amount of unresorbed material. The bone–implant contact (BIC) scores of the PC and MP+ groups were significantly higher (p < 0.05) than that of the NC group. The connective tissue area of the PC group was the lowest, which was significantly lower than the other groups (p < 0.05). Conclusions: The grafts produced are highly biocompatible and also showed osteoproductivity. Their cost-effectiveness and osteoproductive activity require further investigation.

İntraoral Lipom: Bir Olgu Sunumu Amaç Lipomlar, fibröz doku tarafından lobüllere ayrılan, adipoz doku orijinli, çoğunlukla normal mukoza ile örtülü, asemptomatik, benign mezenşimal neoplazmlardır. Genellikle sebebi bilinmese de etyolojide ailesel yatkınlık, travma, alkol, radyasyon ve bazı kronik hastalıklar suçlanmaktadır. Erkeklerde kadınlara göre daha fazla saptanmıştır. Bu olgu sunumunda yanakta az rastlanan ve oldukça büyük boyutlara ulaşmış lipomun tedavisi sunulacaktır. Olgu Yirmi yedi yaşında kadın hasta, uzun süredir mevcut olan ve boyutları giderek artan sağ yanakta şişlik şikâyetiyle kliniğimize başvurdu. Yapılan muayenede sağ bukkal mukoza bölgesinde yaklaşık 2x2 cm boyutunda, yumuşak kıvamlı, hareketli ve düzgün sınırlı kitle tespit edildi. Lokal anestezi altında intraoral yaklaşımla kitle total olarak eksize edildi. Histopatolojik inceleme sonucu, lipom olarak gelen hastanın, 2 yıllık takibinde nüks görülmedi. Bulgular Lipomlar, kapsüler adipoz dokunun benign neoplazmları olup, genellikle subkutanöz dokularda görülseler de derin dokularda da görülebilirler. Maksillofasiyal bölgede nisbeten az rastlanırlar. En sık parotis bölgesinde görülürler, bunu yanak izler. Tanı amacıyla ince iğne aspirasyon biyopsisi, ultrason, BT ve manyetik rezonans görüntüleme yöntemleri kullanılmaktadır. Ayrıcı tanıda, fibroepitelyal polip, anjioma, dermoid kist, fibroma ve liposarkom düşünülmelidir. Temel tedavi şekli cerrahi eksizyon olan lipomlar, fonksiyonel veya kozmetik nedenlerle eksize edilebilirler ve total rezeksiyonu takiben genellikle rekürrens göstermezler. Sonuç Lipom benign bir tümör olup tüm vücutta yaygın görülmekle beraber ağız içi lipomlar, rutin diş muayeneleri sırasında fark edilebilen nadir bir antitedir. Etyolojisi net olarak bilinmemektedir. Kesin tanı ve tedavisi için cerrahi eksizyon uygundur. Bukkal bölgedeki lipomlar intraoral yolla güvenli bir şekilde total olarak eksize edilebilir. Bu olguda total olarak eksize edilen lipomun 2 yıllık takibinde herhangi bir şikâyet ve nüks görülmedi. Anahtar kelimeler: bukkal mukoza, oral lipom, patoloji

ÖZ Amaç : Anksiyete korku, sıkıntı ya da kuruntunun meydana getirdiği belirgin huzursuzluk durumudur. Belli bir aşamaya kadar gayet normal olan bu duygu, anormal seviyeye çıktığında kişinin yaşamını, sosyalliğini ve faaliyetlerini etkileyebilir. Dental anksiyete ise, genel anksiyeteye nazaran daha spesifik olarak değerlendirilebilir. Bu anksiyeteyi; diş tedavileri için kişide oluşan endişe olarak açıklayabiliriz. Dental anksiyetesi olan bireylerin diş hekimi tarafından farkedilmesi, uygulanacak tedavilerin ne gibi protokollerle yapılması gerektiğinin bilinmesi bakımından ciddi önem arz eder. Çalışmamızın amacı, gömülü 3.molar cerrahisi öncesinde uygulanabilecek 3 farklı bilgilendirme tekniğinin karşılaştırılması ve ideal bilgilendirme yönteminin araştırılmasıdır. Gereç ve Yöntemler : Bu çalışma, herhangi sistemik veya psikolojik problemi olmayan, yaşları 18 ile 44 arası değişen, 29’u erkek 31’u kadın olmak üzere 60 gönüllü hasta üzerinde gerçekleştirilmiştir. Hastalar 3 gruba ayrılmıştır. İlk gruptaki hastalara gömülü 3.molar diş çekimi ile ilgili sözlü bilgilendirme yapılmıştır. İkinci gruptaki hastalara bu cerrahiyi anlatan 8 adet fotoğraf gösterilmiştir. Son gruba ise gömülü 3.molar cerrahisini gösteren bir video izletilmiştir. Hastalardan gömülü 3.molar diş çekimi ve bilgilendirme öncesi MDAS, STAIS, STAI-T anketlerini doldurmaları istenmiştir. Tüm hastalardan, bilgilendirme yapıldıktan hemen sonra MDAS ve STAI-S anketini tekrar doldurmaları istenmiştir. İşlem bittikten hemen sonra VAS anketi uygulanmıştır. Tüm hastalara operasyondan 1 hafta sonra MDAS, STAI-S ve VAS anketi uygulanmıştır. Bulgular: Üç grupta da preoperatif dental anksiyete skorları bilgilendirme yapıldıktan sonra azalmıştı.İstatistiksel olarak anlamlı azalma videolu bilgilendirme grubunda gözlemlendi. Sonuç olarak, çalışmamızda hastaları görsel olarak bilgilendirmenin anksiyeteyi azaltma üzerine daha etkili olduğu kanaatindeyiz. Bu durum, hem hasta hem de hekim için daha uygun bir çalışma ortamı hazırlanmasına yardımcı olmaktadır.

Amaç Odontomalar çenelerde en sık görülen odontojenik kökenli iyi huylu tümörlerdir. Yavaş büyürler ve agresif davranış göstermezler. Genellikle asemptomatiktirler ve sıklıkla rutin radyografi sırasında bulunurlar. Kompleks ve kompaund odontoma olarak ikiye ayrılmaktadır. Bu vaka serisinde 8’i komplex 14'ü kompaund, toplam 22 odontoma vakasının cerrahi tedavisinin anlatılması amaçlanmıştır. Olgular Sunumu Yaş aralığı 10-34 arası olan 14’ü kadın 8’i erkek toplam 22 hasta, bölümümüzde gerekli klinik ve radyolojik muayenelerden sonra cerrahi olarak opere edilmiştir. Çıkarılan dokuların histopatalojilerinin, radyolojik ve klinik bulgularla değerlendirilmesi ile 8’inin komplex 14’ünün kompound odontoma olduğu tespit edilmiştir. Bazı vakalarda odontoma ile birlikte gömülü diş alınırken bazı vakalarda diş sürmesinin takibi amacıyla veya çene fraktürü riski sebebiyle etken gömülü dişler bırakılmıştır. İyileşme süresince hastalarda herhangi bir komplikasyon görülmemiştir. Sonuç Odontomalar genellikle asemptomatik görüldükleri için hastaların diş hekimlerine rutin kontrollere gelmeleri, erken teşhiste çok önemlidir. Erken teşhis ile morbidite ve maliyet azaltılabilir.
