Abstract

ObjectiveTo determine the timing and sequence of eruption of primary teeth in children with complete bilateral cleft lip and palate.Material and MethodsThis cross-sectional study was conducted at the Hospital for Rehabilitation of Craniofacial Anomalies of the University of São Paulo, Bauru, SP, Brazil, with a sample of 395 children (128 girls and 267 boys) aged 0 to 48 months, with complete bilateral cleft lip and palateResultsChildren with complete bilateral clefts presented a higher mean age of eruption of all primary teeth for both arches and both genders, compared to children without clefts. This difference was statistically significant for all teeth, except for the maxillary first molar. Mean age of eruption of most teeth was lower for girls compared to boys. The greatest delay was found for the maxillary lateral incisor, which was the eighth tooth of children with clefts of both genders. Analyzing by gender, the maxillary lateral incisor was the eighth tooth to erupt in girls and the last in boys.ConclusionThe results suggest an interference of the cleft on the timing and sequence of eruption of primary teeth.

Summary

Introduction

The period of eruption of primary teeth is LQÀXHQFHG E\ VHYHUDO IDFWRUV VXFK DV OHQJWK RI gestational period, disease, gender, race, nutrition and general growth. Cleft lip and palate may influence the timing and sequence of eruption of both primary and permanent teeth. Cleft lip and palate may influence the timing and sequence of eruption of both primary and permanent teeth2,13,21 This malformation causes injury to the face in many different manners, depending on its occurrence, resulting in morphological and functional incapacity to variable extents. Few studies have mentioned the timing of eruption of primary teeth in children with clefts. Fishaman (1970) evaluated both primary and permanent dentitions and observed an evident delay in the timing of tooth eruption in patients with different types of clefts, the greatest delay occurring for bilateral clefts and for the maxillary lateral incisor on the cleft side
