Evaluation of dehiscence and fenestration in adolescents affected by bilateral cleft lip and palate using cone-beam computed tomography
We evaluated the dehiscence and fenestration presence in maxillary and mandibular anterior teeth of patients affected by bilateral cleft lip and palate (BCLP) and compared the findings with a well-matched control group of noncleft patients using cone-beam computed tomography.Methods
Cone-beam computed tomography images of 51 patients were divided into 2 groups (group 1, 21 patients affected by BCLP; mean age; 14.62 ± 2.89 years; and group 2, 30 patients as the noncleft control group; mean age, 14.22 ± 1.05 years) and assessed them for dehiscence and fenestration in the anterior maxillary and mandibular teeth. Data were analyzed with the Student t test, Pearson chi-square test, and Fischer exact test.Results
The prevalences of dehiscence in patients affected by BCLP were 61.11% in the maxillary and 48.41% in the mandibular anterior teeth, whereas the rates in the noncleft group were 7.78% and 16.67%, respectively (P < 0.001). The presence of fenestration was found to be statistically significantly higher in the maxillary central incisors of the BCLP group compared with the noncleft controls (P < 0.05), and almost similar rates were noted for the other teeth, with no statistically significant differences (P > 0.05).Conclusions
Our data suggest that patients affected by BCLP may have higher prevalences of dehiscence in the maxillary and mandibular anterior teeth and of fenestration in the maxillary central incisors.
