Background: The aim of the study is to retrospectively examine panoramic radiographs and to determine the prevalence of all types and subtypes of encountered dental anomalies. Methods: In the last 6 months of 2019, the radiographs of 1266 patients aged between 14 and 70 who applied to a faculty hospital and had panoramic xrays were analyzed. 5 types as condition, size, number, shape and structure, 21 subtypes in total developmental tooth anomalies such as (Transposition, Ectopy, Inversion, Median diastema, Microdontia, Macrodontia, Hypodontia, Oligodontia, Anadontia, Supernumerary, Meziodens, Talon tubercle (dens evaginatus), Taurodontism, Dilaseration, Gemination, Fusion, Concrescence, Dens in dente (dens invaginatus), Amelogenesis imperfecta, Dentinogenesis imperfecta, Dentin dysplasia) were investigated. Independent sample t-test was used for the mean age, chi-square and Fisher's Exact test were used to evaluate the distribution of anomalies. Results: Dental anomaly was observed in 27.8% of the patients with a mean age of 36.9 years. The prevalence of anomaly in women (30.3%) was significantly higher than in men (23.8%). The prevalence of shape anomaly (68.6%) and talon tubercle (40.3%) as a subtype is significantly higher in women. There was no statistically significant difference between other anomaly subtypes and genders. The most common anomalys are talon tubercle (36.1%), dilaceration (15.3%), median diastema (12.8%), single tooth missing (11.9%), and dens in dente (11.6%) lower types were found. Conclusion: As a result of the study, it was seen that there is a possibility of encountering a dental anomaly in one out of every four patients. The importance of taking panoramic radiographs from each patient and examining them in detail has been seen once again. Keywords: Dental anomaly; Panoramic radiography; Prevalence.
