Objective: The aim of the present study was to determine the prevalence of supernumerary teeth with by evaluating a large group of adult patients in Turkey and to investigate the characteristics of supernumerary teeth with their complications and treatment options. Study Design: This descriptive and retrospective study was carried out in 7348 adult patients aged over 18 years (3212 females and 4136 males). The characteristics of the supernumerary teeth were noted and the diagnosis was made during clinical and radiographic examination with the help of panaromic, periapical, and occlusal radiography. Information on the demographic variables for each patient, including age and gender, were colleceted. Materials and Methods: All supernumerary teeth were classfied under several titles such as location, position, morphology, eruption, clinical complications, and treatment protocols. The data obtained were subjected to statistical analysis. Chi-squared test was used to determine differences in distribution of supernumerary teeth when stratified by gender. The statistical significance was established by confidence interval of 95% (P ≤ 0.05). Results: 123 (2.14%) affected patients (69 females and 54 males) were observed with a female:male ratio of 1.28:1 (P < 0.05). One hundred and fifty-six supernumerary teeth were detected in all affected patients. Conclusion: Supernumerary teeth may be observed in adults patients with a similar frequency (2.14%) as in children and young adolescents, and clinicians should take measures and examine all patients carefully even at older ages.
