PEREIRA, Andrea Cardoso; NISHIYAMA, Celso Kenji  e  PINTO, Lidiane de Castro. Dental anomalies in individuals with unilateral cleft lip and palate and endodontic treatment. RFO UPF [online]. 2013, vol.18, n.3, pp. 328-334. ISSN 1413-4012.

Objective: the aim of this study was to determine the prevalence of dental anomalies on the teeth which are positioned on the side of the cleft in individuals with unilateral cleft lip and palate and relate these anomalies to the difficulties concerning endodontic treatment, when necessary. Subjects and method: the comparative analysis was realized on the teeth adjacent to the cleft and its corresponding homologues, through panoramic radiographs. The radiographic observation was analyzed by an examiner using a magnifying glass, in a vertical negatoscope in the Radiographic Interpretation Room of HRAC-USP. The sample comprised subjects whose ages ranged from 9 to 37 years, who had permanent anterior teeth, with, at least a pair of homologues, presenting coronary and radicular conservation which allowed the radiographic interpretation of the whole pulpar area, without any previous endodontic and orthodontic treatment. Results: a total of 592 panoramic radiographs were analyzed, considering that 106 were according to the inclusion criteria. The most common anomaly found was dilaceration (78.30%), followed by rotated teeth (24.53%), microdontia (15.09%) and macrodontia (1.89%). For the statistical analysis, it was applied the Fisher Exact Test, and only macrodontia did not present statistically significant difference. The upper central left incisor presented most anomalies (58.82%). Male individuals presented higher prevalence (66.04%) and most of the individuals presented unilateral cleft lip and palate on the left side (68.87%). Conclusion: these results suggest that dental anomalies found in this study can affect the endodontic treatment and the professional must recognize them and take specific care and precautions during the treatment.
