This study aimed to analyze the dimensional alterations of the dental arches of 5-year-old children with cleft lip and palate and to compare these dimensions with children without oral clefts. One hundred twenty children were divided into the following groups: unilateral cleft lip (UCL), unilateral cleft lip and palate (UCLP), cleft palate (CP), and control (C). A specific software was used to digitize the dental casts and perform the anthropometric analyses through the measurement of transversal linear intercanine and intermolar distances on the maxilla and mandible. The intergroup comparisons of the maxillary dimensions exhibited that the intercanine distances of groups C and UCL were statistically greater than that of groups UCLP and CP. The intermolar distance was significantly smaller in group UCLP than in the other groups. No statistically significant difference occurred in the mandibular intercanine and intermolar distance among groups. The analysis of the superposition of the maxillary over the mandibular transversal distances showed statistically significant differences among groups. This study showed that at 5-year old, the children with cleft involving the palate had more maxillary dimensional alterations than those without cleft palate.
3D morphometric evaluation of the dental arches of children with cleft lip and palate submitted to different surgical techniques This study aimed to compare the dimensional alterations of the dental arches of children with unilateral complete cleft lip and palate before and after different techniques of primary plastic surgeries. The sample comprised 168 dental casts of children, divided into two groups, according to the performed surgical protocol: Group1 (G1)-children submitted to Millard' technique for lip closure at 3 months of age and Von Langenback's technique for palate closure at 12 months of age; Group 2 (G2)-children submitted to Millard' technique for lip closure and Hans Pichler's technique for anterior palate closure at 3 months of age; and Sommerlad's technique for posterior palate closure at 12 months of age. The dental arches were evaluated before the primary surgeries (T1), after the first phase of primary surgeries (T2), and one year after the second phase of primary surgeries (T3). The dental casts were digitized and measured by using the stereophotogrammetry software. The following distances of the dental arches were measured: intercanine (CC'), inter-tuberosity (TT'), anterior arch length (I-CC'), total arch length (I-TT'), anterior cleft width (PP'), posterior cleft width (UU'), area of greater palatal segments (PSgreater), area of smaller palatal segments (PSsmaller), cleft area (CA), and total area (TA). To analyze the intra-and interexaminer reproducibility, Interclass Correlation Coefficient (ICC) was used. Repeated measures ANOVA (followed by Tukey test or dependent t test) analyzed the intragroup comparison. Independent t test was used to verify the intergroup differences at the evaluated phases (p<0.05). Group 1 exhibited statistically significant differences for the following measurements: CC
<p><strong>Objective:</strong> This cross-sectional study aimed to evaluate the impact of malocclusion on the oral health-related quality of life (OHRQoL) in Brazilian children with non-syndromic oral clefts at tertiary craniofacial center. <strong>Material and methods: </strong>Sixty-nine children with non-syndromic oral clefts, aged between 8 and 10 years, were selected and divided into groups according to the cleft type: Group 1 – Children with complete unilateral cleft lip and alveolus; Group 2 – Children with unilateral cleft lip and palate; Group 3 – Children with cleft palate. Each child answered the Child Perceptions Questionnaire8-10 (CPQ 8-10) which is a multiple-choice questionnaire, with 29 questions on the impact of oral diseases on the OHRQoL. Then, a visual examination of dental occlusion was carried out. Kruskal-Wallis and Mann-Whitney tests were used to determine statistical significant differences among groups (p<0.05). <strong>Results: </strong>No statistically significant differences were verified for the impact of cleft type (p=0.895) and malocclusion (p=0.528) on OHRQoL of Brazilian children with oral clefts. <strong>Conclusion: </strong>The malocclusion did not impact on the OHRQoL of 8-10 year-old children with non-syndromic clefts.</p>
