Considering the essential need for oral health-related quality-of-life measures for patients with craniofacial malformations, the current study aimed to investigate the oral health-related quality of life of Iranian patients with cleft lip and palate. Fifty children referred to Cleft lip/Palate Research Center of Mashhad Dental School (Iran) were recruited. Participants were asked to complete the Child Oral Health Impact Profile questionnaire. The questionnaire comprised 38 items and was divided over 5 subscales. The scores on all subscales were compared with regard to patients' age, sex, and type of cleft. A significant difference between boys and girls was found on the subscale "emotional well-being" (P = 0.027). There was no significant difference between 8- to 12-year-old patients and those older than 12 years. Also, no significant difference was found between bilateral and unilateral cleft lip and palate patients regarding mean score of Child Oral Health Impact Profile questionnaire and its subscales. Oral health-related quality of life of cleft lip and palate patients did not change with patients' age. Also, the impact of unilateral and bilateral clefts on OHRQoL was similar. Quality of life of girls was more affected by oral health.
The aim of the present study was to investigate the prevalence of dental anomalies in a group of patients with cleft lip and palate (CL/P) in the northeast of Iran. Ninety-one patients referring to the Cleft Lip and Palate Clinic of Mashhad Dental School were enrolled and classified into right CL/P, left CL/P, and bilateral CL/P groups. Photographs, dental casts, and panoramic and periapical radiographs were retrieved, and dental anomalies were recorded. χ test was used to analyze the frequency of dental anomalies according to type of cleft and sex. Missing maxillary lateral incisors was the most frequent dental anomaly, which was slightly higher in the bilateral group (61.1%). There were significantly more cases of missing lateral incisors outside the cleft area in right CL/P (P = 0.015). Peg lateral incisors were observed in 33.3% of bilateral CL/P compared with 28% of right and 23.3% of left unilateral cases. The sample presented rotations of central incisors in the cleft area in 33.3% of bilateral clefts. In unilateral clefts, it occurred more frequently in the right side (48%). Sexual dimorphism appeared only for maxillary central incisor rotation in the cleft area, which showed significantly greater frequency in females (P = 0.025). Transposition of maxillary canine and first premolars was found in 5.5% of bilateral, 8% of right, and 3.3% of left unilateral clefts. The prevalence of dental anomalies in the studied sample seems to be higher than that reported in the normal population. More anomalies were observed at the cleft side. The frequency of most anomalies was not significantly different between the 2 sexes.
