Abstract

Aim: To assess the incidence of congenitally missing mandibular incisors in patients reporting for orthodontic treatment.

Introduction: Hypodontia is the most common condition reported among people. Missing mandibular incisors plays an important role in planning the treatment in the field of orthodontics. The knowledge on the mandibular teeth agenesis and other different tooth positions aids in analyzing the etiological basis of the orthodontic treatment.

Materials and methods: A total of 962 patients' case sheets were taken in the present study. From which, 155 patients were categorized under the orthodontic population and 807 patients under the general population. The prevalence and average missing of the mandibular incisors were analyzed in both the groups using intraoral images and panoramic radiograph.

Results: The prevalence of missing mandibular incisors among orthodontic and general population were 8.38% and 1.11% respectively. Tooth number 31 (50%) is found to be the most commonly missing teeth followed by 41, 32 and 42. Females show a high incidence of missing lower incisors compared to males. And also, females have more missing teeth than males.

Conclusion: Hypodontia is found considerably more frequent in mandibular incisors in orthodontic patients. Early detection of missing teeth can obtain a satisfactory permanent dentition and to reduce the complications of hypodontia.
