Abstract in Portuguese
Objetivo: Registrar em incisivos centrais e primeiros molares superiores e inferiores permanentes de pacientes com fissura de lábio e/ou palato e sem fissura a prevalência de defeitos de esmalte e sua relação com a fissura. Modelo: Estudo transversal. Local de execução: Setor de Odontopediatria do Hospital de Reabilitação de Anomalias Craniofaciais - Universidade de São Paulo (HRAC-USP), Bauru/SP ? Brasil e na Escola Estadual, Agudos/SP ? Brasil. Participantes: 100 pacientes, regularmente matriculados no HRAC-USP, sendo 50 com fissura de lábio e palato e 50 com fissura isolada de palato e 50 pacientes sem fissura pertencentes à Escola Estadual-Agudos, de ambos os sexos, de 6 a 12 anos. Metodologia: A freqüência, a extensão e a localização das alterações de esmalte na face vestibular dos dentes foram avaliadas clinicamente, segundo o índice DDE modificado, após teste intra-examinador. Resultados: Existiu maior manifestação dos defeitos de esmalte em incisivos e molares superiores nos grupos com fissuras, com significado estatístico, quando comparados ao grupo NF. Os terços médio e cervical dos incisivos superiores nos grupos com fissura envolvendo o alvéolo, principalmente no dente do lado fissurado e os terços incisal e médio nos grupos com FP e NF foram os mais acometidos; nos incisivos inferiores e molares superiores os defeitos ocorreram mais nos três terços dentários avaliados e no molares inferiores nos terços oclusal e médio para os grupos com FP e FLP. A opacidade apresentou a maior ocorrência em todos os grupos estudados. Conclusões: Os resultados mostraram que a ocorrência de defeitos do esmalte foi comum nos incisivos e molares permanentes estudados e sua relação com a fissura é um fator clínico importante que deve ser considerado.

Results: There was a higher demonstration of enamel defects in maxillary incisors and molars in group with cleft, with result statistically significant when was compared with group without cleft. The middle and cervical thirds of maxillary incisors on the group with complete cleft mainly of the teeth cleft side and incisal and middle thirds most affected in group cleft palate and group without cleft; the larger prevalence of enamel defects in mandibular incisors and maxillary molars was observed in three thirds of teeth and oclusal and middle thirds for mandibular molars the patients with cleft palate and cleft lip and palate. Enamel opacity was observed with greater prevalence in all studed groups. Conclusions: Results show that the occurrence of enamel defects is common in studed permanents incisor and molars and its association with cleft is an important clinical factor to be considered.
