Evaluation of the Prevalence of congenitally permanent tooth agenesis among pediatric patients in the subregion of Antalya

Aim: This research aimed to ascertain the prevalence of congenitally permanent teeth agenesis, excluding third molars, among children residing in the subregion of Antalya, Turkey. Material and Methods: A retrospective evaluation of panoramic radiographs from 3234 children (1567 females, 1667 males) aged 6 to 12 years was conducted. Participants with systemic illnesses, extracted teeth, ongoing orthodontic interventions, and congenital abnormalities were excluded. Chi-square test and One Sample Chi-square test were employed for comparing qualitative data. Results: The study cohort exhibited a mean age of 9.02±1.99 years. The prevalence of congenitally permanent teeth agenesis was determined to be 1.9%, with a distribution of 2.3% among females and 1.6% among males, although no statistically significant disparity was observed between genders (p>0.05). Notably, a statistically significant difference in the occurrence of tooth agenesis was noted among the jaws (p<0.05), with a notably higher incidence observed in the mandibular region compared to the maxillary region (p<0.05). Mandibular second premolars represented the most frequently absent teeth, accounting for 77.9% of cases, a finding deemed statistically significant (p<0.05). Additionally, maxillary second premolars exhibited a notable prevalence of 15%, a proportion significantly higher than that observed for maxillary lateral incisors, mandibular lateral incisors, mandibular central incisors, and left mandibular first premolars (p<0.05). Conclusion: The prevalence of congenitally teeth agenesis varies across populations. Timely and accurate diagnosis of agenesis of permanent teeth is essential to facilitate the development of a comprehensive long-term treatment strategy and improve prognostic outcomes in affected individuals.
