Current data on the characterization of oral clefts in Brazil

Abstract

ABSTRACT:This study aimed at investigating the current distribution of the several types of clefts among the patients receiving treatment at the Hospital for Rehabilitation of Craniofacial Anomalies (HRAC-USP), Bauru, Brazil, for the first time during the year 2000. A total of 803 unoperated patients with cleft lip and/or palate, with or without additional malformations, with no recognizable syndromes, who came to the HRAC-USP for enrollment for treatment during the year 2000. A predominance of complete cleft lip and palate, either unilateral or bilateral, was observed (37.1%), followed by isolated cleft palate (31.7%) and isolated cleft lip (28.4%). A discrete relationship between cleft palate and the female gender was noticed (53%), and males were more affected by the other types of clefts (around 60%). The findings revealed a predominance of complete clefts of the primary and secondary palate, the treatment of which is more complex, and whose frequency is greater in males.

Analysis of familial incidence of non-syndromic cleft lip and palate in a Brazilian population

“…Recently, in a Brazilian population study, we showed predominance of CLP (52.6%), followed by isolated CL (33.12%) and isolated CP (14.28%) (8). In most published studies, the percentage of subjects with CLP has been higher compared to that of CL or CP alone, including the Brazilian studies (8,12). Some authors studying a population in Sucre, Bolivia, attributed the highest incidence to CL alone (13).…”

Prevalence of orofacial clefts and social factors in Brazil

“…20 Similar results were observed in a study of the distribution of cleft types in patients attended at a University Hospital in São Paulo. 21 It was observed that 70% of the cases lived under unfavorable socioeconomic conditions.…”

Anomalias dentárias em indivíduos com fissura transforame incisivo unilateral e o tratamento endodôntico

“…Neste trabalho, observa-se maior predominân-cia das fissuras labiopalatinas no gênero masculino, o que corrobora os achados de outros autores, com exceção das fissuras pós-forame incisivo, que acometem mais o gênero feminino [13][14][15][16] . A fissura transforame incisivo unilateral foi escolhida por permitir a comparação dos dentes com o lado não fissurado.…”

“…A fissura transforame incisivo unilateral foi escolhida por permitir a comparação dos dentes com o lado não fissurado. A maior prevalência desse tipo fissura do lado esquerdo, neste trabalho, é concordante com o resultado de Freitas et al 13 , que encontraram ser esta a de maior frequência no HRAC-USP.…”
