ABSTRACT
The purpose of this retrospective observational study was to evaluate the possible association between the missing teeth and the side associated with the cleft in non-syndromic patients. This study consisted of 201 cleft patients including 131 males with a mean age of 12.3 ± 4 years and 70 females with a mean age of 12.6 ± 3.9 years. 148 of the patients were affected by cleft lip and palate, while the other 53 presented only cleft lip. Charts, models, radiographs, and intraoral photographs were used for the study. T-test and chi-square tests were used for the assessment of the data. Hypodontia was found in 129 individuals (64.1%). Chi-square test showed that there was no statistically significant difference between the number of male and female patients with hypodontia (P<0.7). 122 of the patients with hypodontia (60% of the total 201 subjects) had missing maxillary incisors. Totally there were 197 teeth absent in the entire cleft samples. 180 (91.3%) of these teeth were missing on the cleft side and 17 (8.7%) of them were missing on the non-cleft side. In addition, 170 (86.3%) of them were maxillary permanent lateral incisors and only 27 (13.7%) of them were permanent second premolars. The frequency of missing maxillary lateral incisors in cleft lip patients was significantly higher compared with the missing second premolars in both arches. The incidence of lateral incisor missing is significantly higher on the cleft side.
