Desenvolvimento de caninos permanentes de crianças fissuradas da Paraíba.

Abstract

INTRODUCTION: The study of dental development through panoramic radiographs is one of the most reliable methods for estimating age through the dental training process, widely used to evaluate maturity and to calculate chronological age. OBJECTIVE: To evaluate the development of canines of Paraíba children with cleft lip and palate using the methods of Nolla and Demirjian. METHODS: This cross - sectional study was carried out using an inductive approach using a comparative statistical procedure and a direct documentation research technique. The universe consisted of all the children attended at the orthodontics service of the Brazilian Association of Dentistry - Paraíba Section. The sample consisted of 72 pairs of panoramic radiographs of children with and without cleft lip and palate, of the same gender and with a difference of age of up to 30 days, in the age range from 5 to 13 years. Thus, the development of 576 canine teeth was evaluated. All images were evaluated by three duly calibrated examiners at the same time, and the calcification stages were determined by consensus. Panoramic radiographs evaluated calcification rates of canine teeth according to the Nolla and Demirjian classification. RESULTS: The means of the stages were correspondingly higher in the case group than in the control group, showing delayed development of canine teeth in the fissured patients. The upper and lower arches presented significant differences (p <0.05). There were no significant differences between the sides for any of the canine teeth and groups; in addition, dental development occurred earlier in females compared to males. CONCLUSION: In this way, the present study collaborates to improve the knowledge about the development of permanent canines, in order to guide the ideal moment for orthodontic intervention in the fissured patients.
