Abstract
Purpose To focus on the effects of the presence of mesiodens on adjacent teeth and to investigate the timing of its safe removal. Materials and Methods Cone-beam computed tomography examinations, obtained at Okayama University Hospital over a three-year period, were inspected. Data were recorded including the number of mesiodens; associated abnormalities; and the relationship with neighboring structures. Depending on multiple factors, the risk of developing complications due to early extraction of a mesiodens was divided into three categories: high, medium, and low risk. Results A total of 5,958 cone-beam computed tomography exams were obtained, 460 patients aged 3-85 years were diagnosed with a total of 568 mesiodens, 382 (67.3%) of which were discovered in young patients (age <10 years), and 333 (87.2%) of these were associated with abnormalities. Regarding the risk categories, 11 (1.9%) were considered to be in the high-risk, five (0.9%) in the medium-risk and 552 (97.2%) in the low-risk categories. Moreover, eight out of 11 high-risk mesiodens were extracted and no post-operative complications have been seen. Conclusion As the results showed that no postoperative complications were seen in all the extracted cases of high-risk mesiodens, this indicates the possibility of safe extraction at an early age which could reduce related future complications.

Epidemiology of Supernumerary Teeth in 5000 Radiography Films: Investigation of Patients Referring to the Clinics of Ardabil in 2015-2020. Int J Dent 2021; 2021:6669436. [PMID: 33688347 PMCID: PMC7925020 DOI: 10.1155/2021/6669436] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 01/08/2021] [Accepted: 02/15/2021] [Indexed: 11/18/2022] Open
Abstract
Background Supernumerary tooth is defined as any extra tooth or odontogenic structure that is formed on normal dentition. Supernumerary teeth cause such problems as deficiency in tooth growth, ectopic growth, displacement, crowding, diastema, odontogenic cyst formation, decay of the adjacent tooth, malocclusion, and esthetic problems. This study was conducted aiming at determining epidemiology of supernumerary teeth in Ardabil city in 2020. Materials & Methods. In this retrospective descriptive analytical study, 5000 panoramic radiographs of patients referring to Rad and Baser Oral and Maxillofacial Radiology Centers were selected through multistage sampling method during 2015-2020. The data were collected by checklist and analyzed with using SPSS-21 and chi-squared, Fisher, and one-way ANOVA tests with a significance level less than 5%. Results The prevalence of supernumerary teeth was estimated as 1.06% (n = 53), and no significant difference between the males and females was seen. Most supernumerary teeth were found in the distomolar (44.1%) and parapremolar (29.4%) locations. The majority of supernumerary teeth were present in the maxilla (73.5%) and were impacted (77.9%) and unilateral (71.7%). The number of supernumerary teeth was 68 cases and majority of patients (86.8%) had one supernumerary tooth. Conclusion Supernumerary tooth in this study had a high prevalence compared to similar studies, and unlike most previous studies, the most common type of supernumerary tooth was distomolar. Early diagnosis and proper medical planning are essential for managing supernumerary teeth.
