Abstract :

OBJECTIVE: This study aimed to determine the prevalence and distribution of non-syndrome- related oligodontia in Turkish children in Isparta and its surroundings. MATERIALS AND METHOD: The records of patients who were admitted to the Department of Pedodontics, Faculty of Dentistry of Süleyman Demirel University between 1999-2018, and diagnosed with oligodontia were searched. One-hundred-twelve individuals between the ages of 6 and 18 who did not have any systemic disorders, and missing ≥6 teeth except the third molars were included in the study. The distribution of detected tooth agenesis according to missing teeth, gender, and jaws and tooth agenesis patterns were examined. The frequency of tooth agenesis was given in numbers-percentages, and the Mann-Whitney U test was applied to the distribution of gender and missing teeth. The frequency analysis was calculated using Tooth Agenesis Code (TAC) values to determine tooth agenesis patterns. RESULTS: The incidence of non-syndrome-related oligodontia in Turkish children in Isparta and its surroundings was found to be 0.08%. The number of missing teeth per individual was found to be 9.05 and the most commonly missing teeth were observed as lower/upper second premolars. When the tooth agenesis was compared between genders and jaws, the differences were not statistically significant. Commonly observed tooth agenesis patterns were a combination of premolars and lateral incisor. CONCLUSION: According to the results, in Isparta and its surroundings, the presence of oligodontia was detected in 8 out of 10,000 children. Along with the early diagnosis, alternative treatment can be applied considering the severity and distribution of oligodontia.
