Dental agenesis in cleft lip and/or palate pf the “Centro Pró-Sorriso” – Universidade José do Rosário Vellano
Abstract
Objective: Analyze periapical and panoramic radiographs in order to define the incidence of dental agenesis in carriers of cleft lip and/or cleft palate among patients of UNIFENAS “Centro Pró-Sorriso” (Pro-Smile Center) in Alfenas – MG. Methods: Periapical and panoramic radiographs from recorders of 172 patients treated at Centro Pró-Sorriso (Center Pro-Smile) of UNIFENAS in Alfenas,MG, for cleft lips and palates, unilateral or bilateral, complete or incomplete, in both genders, aged from 0 to 15 years. Results: From the total above mentioned 172 patients fulfilled the requirements, ninety eight (57.0%) presented cleft lips, alveoli and palates. 32 (18.6%) presented cleft lip and alveolus cleft: 28 (16.3%) presented only cleft palate. 14 (8.1%) presented only cleft lip. The masculine gender predominated in all types of cleft except for right lip and palate cleft, at which the feminine gender was preeminent. Inthe relation between ethnical characteristics and type of cleft, disregarding the side of incidence, no significant difference was noticed. The greatest incidence of cleft lip, alveolus (LAP) and palate occurred as follows: 47 (27.35%) on the left side; 31 (18.0%) were bilateral; 20 11.6%) on the right side. In the group of lip and alveolus cleft, 17 (9.9%) were on the left side; 11 (6.4%) in the right side, and 4 (2.3%) were bilateral. In the group of lip cleft only, 11 (6.4%) were on the left side, and 3 (1.7%) in the right side. If the regions of incidence(right, left, bilateral) are considered, regardless of the type of cleft, the incidence on the left side was significantly greater than at right or the bilateral modality. No significant difference was noticed between the right side and the bilateral modality. Conclusion: he incidence of LAP cleft was significantly greater than that of the other types, and LA clefts were statistically more numerous than L cleft. With respect to LA clefts, the left side prevailed over the bilateral modality. 60.9% being of agenesis.
