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.


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.


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).


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.
