ABSTRACT

PURPOSE: To determine the prevalence of dental anomalies in 200 cleft patients undergoing orthodontic treatment at the Cleft Rehabilitation Center (CERLAP) of the Pontifical Catholic University of Rio Grande do Sul.
METHODS: Data regarding patient age, race, gender, cleft type (lip and alveolus, complete lip and palate, or cleft palate), affected side (unilateral or bilateral), agenesis and supernumerary teeth in both arches were assessed from orthodontic records comprised by panoramic, cephalometric, occlusal, and periapical radiographs, study models, intra- and extraoral photographs, obtained at the beginning of the treatment, providing needed information to make an accurate diagnosis of dental anomalies. The collected data were registered in spreadsheets.
RESULTS: The mean patient age was 13.5 years old; 86% were white; and 57% male. Complete cleft lip and palate was found at a higher frequency (83%); the left side was most affected (48.5%). Agenesis were found in 66.5% of patients. Maxillary lateral incisors were the most absent teeth (78.5%). Supernumerary teeth were found in 35.5% of patients.
CONCLUSION: Male individuals demonstrated a greater tendency to present clefts and manifest both agenesis and supernumerary teeth. Complete cleft lip and palate prevailed, and the left maxillary lateral incisor was the most absent tooth. Supernumeraries were located distally to the cleft.

Key words: Cleft palate; anodontia; tooth, supernumerary; epidemiology

RESUMO

]]> OBJETIVOS: Determinar a prevalência de anomalias dentárias em 200 pacientes com fissura sob tratamento ortodôntico no Centro de Reabilitação Lábio-Palatal (CERLAP) da Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS).
METODOLOGIA: Os dados referentes à idade, raça, gênero, tipo de fissura (pré, trans ou pós-forame incisivo), lado afetado (uni ou bilateral), agenesias e supranumerários em ambas arcadas foram avaliados a partir da documentação ortodôntica constituída por radiografias panorâmicas, cefalométricas, oclusais e periapicais, modelos de estudo e fotografias intra e extrabucais obtidas no início do tratamento, fornecendo informações necessárias para diagnóstico de anomalias dentárias. Os dados coletados foram registrados em planilhas.
RESULTADOS: A média de idade dos pacientes foi de 13.5 anos; 86% eram brancos; e 57% eram meninos. Fissuras transforame incisivo demonstraram-se mais frequentes (83%); o lado esquerdo foi mais afetado (48.5%). Agenesias foram encontradas em 66.5% dos pacientes. Incisivos laterais superiores foram os dentes mais ausentes (78.5%). Supranumerários foram encontrados em 35.5 % dos pacientes.
CONCLUSÃO: Meninos demonstraram maior tendência a apresentar fissuras e a manifestar agenesias dentárias e supranumerários. As fissuras completas de lábio e palato prevaleceram e os incisivos laterais superiores foram os dentes mais ausentes. Os supranumerários localizaram-se distalmente à fissura na maioria dos casos.
