Prevalence of Dens Invaginatus in Maxillary Lateral Incisors in Patients Visiting Peshawar Dental College and Hospital

Abstract

Objective: Dens Invaginatus is a developmental abnormality that may be found in any tooth but is most commonly noticed in maxillary lateral incisors. This study aimed to find out the prevalence of Dens Invaginatus in maxillary lateral incisors in patients reporting to Peshawar Dental College.

Materials and Methods: The study design was descriptive cross-sectional and conducted in Peshawar Dental College in the Department of Operative Dentistry and Endodontics from December 2021 to May 2022. Four hundred and twenty-eight patients' maxillary lateral incisors were examined clinically for any pit or groove on the palatal surface. Teeth with any clinically detected pit or groove were then confirmed radiographically and the questionnaire was filled. The chi-square test was used to analyze variables such as gender, type and whether dens invaginatus involvement was unilateral or bilateral. P ≤ 0.05 was set significant.

Results: Dens Invaginatus was found in 25 of 428 subjects, with a prevalence of 5.8%. The age of the patients ranged from 12 to 71 years with a mean age of 35±13 years. There were 11 (4.6%) females and 14 (7%) males with Dens Invaginatus. Type I (71%) was the most frequently seen, type II (16%), and type III was seen in 13% of patients. Dens Invaginatus were noticed on both sides in 14 (7%) patients and on one side in 11(4.6%) patients.

Conclusion: The prevalence of Dens Invaginatus in maxillary lateral incisors was 5.8% in Peshawar region. Lateral Incisors were more bilaterally involved. Type 1 Dens Invaginatus were more commonly involved which requires minimal intervention to seal them.
