Introduction, aim: At present, tooth autotransplantation is considered one of the therapeutic methods for the replacement of lost teeth. In the last 30 years, the method of tooth autotransplantation has been developed and refined and has become a basic knowledge of dental practitioners. The aim of this clinical retrospective study was to examine children and adult patients with tooth autotransplantation and obtain survival and success rates. Another aim was to determine other specifics of autotransplantation in each group with conclusions relevant for clinical practice. Methods: The study population consisted of the patients referred consecutively for tooth autotransplantation to a specialist department between years 2016 and 2021. The specialization of the referring dentist, the suitability and feasibility of the transplantation, and the donor and recipient area of the tooth graft were recorded. In 2022, clinical and radiological evaluation of the autotransplanted teeth was performed. Patients were divided into two groups according to age in time of autotransplantation, namely under 18 years and over 18 years. Results: Overall, 73 patients in the age range of 10-59 years were referred for autotransplantation. The mean age was 21.43 years with a median age of 17 years. Autotransplantation was not recommended in 12 patients. A total of 68 autotransplantations were performed, but at the time of examination, 12 did not meet the minimum 6-month follow up, so they were excluded from the evaluation. A total of 56 autotransplants were evaluated. In the group of children, there were 27 patients aged 10-17 years who underwent autotransplantation of at least one permanent tooth. A total of 34 teeth were transplanted. The evaluation of the transplanted teeth was performed 6-50 months after the transplantation with a mean follow-up time of 24 months. The survival rate was 100% and the success rate was 91%. The adult group consisted of 22 patients aged 18-59 years and a total of 22 teeth were transplanted. The evaluation of the transplanted teeth was performed 6-72 months after transplantation with a mean of 33 months. The survival rate was 95%, the success rate 77%. Conclusion: The use of autograft to replace undeveloped or lost teeth was most often indicated by orthodontists. In the patients under 18 years of age, the premolars are the predominant donor area and recipient area. In patients over 18 years of age, the third molars are the predominant donor area and the mandibular molars the predominant recipient area. Both age groups have high survival and success rates of autograft and this procedure can be considered as a predictable method of tooth replacement.

Introduction: Peri-implantitis is a serious disease affecting the tissues around the dental implant (DI). Non-surgical therapy (NCHT) plays an important role in the management of this disease. One method for NCHT is the treatment with an air abrasive device (MAP). The aim of this prospective, randomized controlled clinical trial was to compare the efficacy of MAP in NCHT of peri-implantitis in combination with or without systemic antibiotic (ATB) therapy. Methods: The population included 33 patients (15 men and 18 women) with a mean age of 55.4 years at the time of first treatment and a total of 88 dental implants (DI) with diagnosed peri-implantitis. Patients were examined and the clinical parameters of probing depth (PD), bleeding on probing (BOP) and suppuration on probing (SOP) were recorded. The patients were then randomly divided into two groups. The first, the test group, initiated the treatment session using the systemic ATB and then continued to use ATB for 7 days after the therapy. The second, control group, underwent the same therapy, without adjunctive ATB treatment. The therapy itself was performed with Airflow plus powder with erythritol crystals applied using a MAP Perioflow® with a Perioflow nozzle (EMS; Nyon, Switzerland). Patients were subsequently called for a follow-up examination 1, 3, 6, 12, and 24 months after the treatment. Results: As part of the control examinations, there was a significant reduction of the PD parameter in both the test and control groups compared to the baseline. The test group had significantly greater differences in PD sum values after 6 months (p = 0.003) and 12 months (p < 0.0001) than in patients without ATB therapy. Conclusion: A reduction in the values of clinical parameters (BOP, SOP, PD) is possible with the use of MAP and erythritol powder, regardless of the systemic administration of ATB. However, the systemic use of ATB as supportive therapy in NCHT of peri-implantitis significantly reduces both PD and BOP compared to the group of patients without systemic ATB.

Introduction: The aim of this article is to present and summarize the non-surgical treatment options in management of peri-implant diseases and compare the effectiveness of the treatment with/without adjunctive use of antibiotics. Methods: A search was conducted in the PubMed- MEDLINE, Scopus, Embase, and Google Scholar databases, and available repositories, followed by a hand search. The relevant clinical studies, reviews, and consensuses about the non-surgical peri-implant therapy published between 1990-2022 in English language were included. Conclusion: Based on the available information, it can be said that there is a great diversity in the treatment of dental implants affected by peri-implantitis. Studies testing different therapeutic protocols are rare and highly heterogeneous. Stabilization of peri-implant disease after the treatment without systemic or local antibiotics is possible, but the reduction of probing depth around the dental implant using only the non-surgical therapy is still insufficient. Non-surgical treatment is therefore successful particularly in solving the peri-implant mucositis and also as a conditioning before surgical therapy.

Introduction, aim: Currently, the tooth autotransplantation is considered a reliable method for the tooth substitution. The aim of this article is to give a comprehensive outline of the studies dealing with tooth transplantation in the Czech dental literature.Methods: A retrospective survey of the Czech dental literature of the years 1920-2021 was done. Namely the journals Zubní lékařství, Československá stomatologie, Praktické zubní lékařství, Ortodoncie, LKS and the Czech version of Quintessenz journal.Conclusion: Overall, 25 studies have been published in the Czech dental literature dealing with the tooth transplantation up to now.

Introduction and aim: The aim of article is to present the new classification of diseases of peri-implant tissues and also summarize the available evidence about their etiology and prevention.Materials and methods: A search was conducted in the PubMed-MEDLINE, Scopus, EMBASE, Google Scholar databases and available repositories, followed by hand search. The relevant clinical studies, reviews and consensuses about peri-implant tissues and their health and diseases which were published between 1990-2021 in English language were included.Conclusion: In the case of knowing the risk factors in developing of disease of peri-implant tissues it is more then appropriate to select eligible patient. The patients with active marginal periodontitis must not be treatetd with dental implants before its stabilization. In the event thatfurther risk factors such as diabetes mellitus or smoking are present we should consider another prosthodontic alternatives. Consecutive follow-up of patient should be initiated immediately after dental implant placement and should be repeated regularly.

Background: The appearance of interdental papillae plays an important role in the final aesthetic outcome, especially in exposed region as is interdental papilla between central upper incisors. The aim of this study, is to determine factors associated with bone morphology, which can influence the appearance of this papilla. Materials and methods: 50 subjects in the range of 20-30 years of age with healthy periodontal tissues were examined. Presence of interdental papilla between central maxillary incisors was determined using classification proposed by Nordland and Tarnow. Intraoral radiographs were utilized to measure distance from contact point to the crest of bone and interdental distance at the level of cementoenamel junction using a computer programme. Results: Statistically significant correlation between papilla presence and distance from the contact point to the crest of bone (p < 0,0001) was found. Also significant relationship between papilla presence and interdental distance (p < 0,0001) was found. The value of prediction of papilla presence for both factors was inferred from data analysis. Conclusion: Presence of interdental papilla is influenced by various factors, including distance from contact point to the crest of bone and interdental distance. Modification of these distances can influence the final aesthetic outcome.

The case reports describes a 43-year female patient, who attended a regional dentist for a dull pain of mandible on the right, swelling of alveolus on the vestibular and lingual side and a beginning swelling of the right cheek. The dentist performed an intraoral incision, drainage and administered antibiotics. A purulent exudation lasted despite this therapy and the patient was therefore sent to a specialized ward. The following clinical and X-ray examination established the diagnosis of periodontal cyst. The antibiotic coverage was applied before extirpation of the cyst, the cavity was filled with augmenting material Poresorb, covered with the HyproSorb membrane and the wound was occluded with feather stitches. The histological examination revealed a keratocyst. In spite of the fact that the patient failed to present any complaints and the wound healed up, two months after the operation the tooth 45 lost its vitality and an endodontic treatment became necessary.
