|Abstract: ||Clefts of the lip and/ or palate (CL/CP) are the most common craniofacial birth defects. Orofacial clefts represent a significant public health problem due to the lifelong morbidity and complex etiology of these disorders. The extensive involvement of CL/CP sample with dental anomalies emphasizes the importance of understanding the relationship between dental anomalies and clefting therefore optimizing diagnosis and treatment planning. The purpose of the present study was to determine the prevalence of the different types of dental anomalies frequently associated with cleft lip and/ or palate in a sample of Saudi patients. This retrospective study and its records (pre-treatment maxillary occlusal radiographs of the cleft region, panoramic radiographs, and study models), were obtained from three different cleft lip and palate centers in the same city of Riyadh, Saudi Arabia.
A total of 200 patients with CL/CP were identified and included in this study, of which 138 subjects were from the College of dentistry, KSU, 42 subjects were from the Riyadh National Guard Hospital and 20 subjects were from the Riyadh Military Hospital. The cleft lip and palate type CLP (134 individuals, 92.2%) was more prevalent in the present sample.
Statistical analysis was conducted using the Pearson Chi-Square test. The distribution of anomalies according to cleft side showed that patients with unilateral cleft lip and palate (UCLP) type had the highest prevalence of dental anomalies (104 individuals, 57%) where the left side was slightly more affected with clefting (LCLP) (54 individuals, 32%), than the right side(RCLP) (50 individuals, 30%). Hypodontia was the most common observed dental anomaly affecting 134 clefted individuals (46.5%), followed by microdontia (91 individuals, 31.6%), ectopic eruption (30 individuals, 10.4%), supernumerary teeth (26 individuals, 9%), and macrodontia (7 individuals, 2.4%).
In the present study, the tooth most commonly missing was the maxillary lateral incisors (148 teeth, 50.9%). The same tooth was highly affected with supernumerary teeth (14 teeth, 45.2%), and Intraoral ectopic eruption (10 teeth, 29.4%). Microdontia was frequently observed in the maxillary central incisors (75 teeth, 43.1%). Intranasal tooth eruption was rare (6 teeth, 1.1%). The least dental anomaly observed was macrodontia, which was highly associated with the mandibular lateral incisors (4 teeth, 33.3%). Dental anomalies were frequently found to be greater on the cleft side (68.6%) than the non-cleft side (31.3%) of the maxillary arch, however, no statistical significance was demonstrated.
The frequency of dental anomalies were greater in our combined sample of cleft lip, cleft palate, and cleft lip and palate in comparison to the non-cleft orthodontic sample and the difference was statistically significant.|
