Abstract

Abstract: PURPOSE: To assess the prevalence of fenestration and dehiscence of anterior teeth in adolescent patients with unilateral cleft lip and palate(UCLP). METHODS: Twenty-five males and seventeen females with UCLP who visited The Second Xiangya Hospital from June 2014 to September 2017 were selected. Forty-two age- and sex- matched non-cleft skeletal III patients were enrolled as the control group. Cone-beam CT（CBCT） scans were evaluated to detect fenestration and dehiscence.The data were analyzed using SPSS 22.0 software package. RESULTS: The prevalence of dehiscence of anterior teeth was 50.88% on the cleft side,42.39% on the non-cleft side and 28.77% on the controls, respectively. Dehiscence of maxillary teeth was more common on cleft side than the controls (P<0.05), and dehiscence of maxillary lateral incisor was common on non-cleft side compared with the control (P<0.05). Maxillary central incisor on the cleft side showed a higher prevalence of dehiscence compared with the non-cleft side (P<0.05). Most of the dehiscence was detected on the buccal side. Fenestration of the teeth showed no significant difference among the cleft side, non-cleft side and the control (P>0.05). CONCLUSIONS: Adolescent patients with UCLP show a high prevalence of fenestration and dehiscence,which deserves to be taken into consideration during clinical treatment.
