ABSTRACT

Significant heterogeneity has previously been reported but with no consensus on the prevalence of dental anomalies in subjects with a cleft lip and palate (CLP), thus, the purpose of this study was to investigate the frequency of various dental anomalies in the upper dental arch in different cleft groups. Diagnostic records, i.e., panoramic, occlusal and periapical films, dental casts, and intra-oral photographs, of 122 subjects (mean age: 14 +/- 5 years; 67 males and 55 females) were grouped as either unilateral left cleft lip and palate (ULCLP), unilateral right cleft lip and palate (URCLP), bilateral cleft lip and palate (BCLP), or cleft palate (CP). Prevalence rates of 15 different dental anomalies were calculated for each group. Wilcoxon's test was used to determine if there was a statistically significant difference in the number of missing teeth between the right and left sides, in each cleft group. Overall, 96.7 percent of patients were found to have at least one dental anomaly. The most prevalent was agenesis in the anterior region on the cleft side (70.8-97.1 percent). There was a statistically significant difference in the prevalence of agenesis by cleft and non-cleft sides but only in the ULCLP group (P < 0.001). Significantly higher rates of impaction were observed in the anterior and premolar regions in the CLP groups (2.9-29.2 percent), with the highest rates in the anterior region on the cleft sides. A very high proportion of subjects were found to have at least one dental anomaly. Thus, the management of dental anomalies should be central to the treatment planning process of individuals with a cleft.

[10] who investigated the prevalence of dental anomalies in patients with cleft lip and palate, and found that a significant proportion of individuals with a cleft had at least one dental anomaly. Similarly to the findings of the current study, Eslami et al. [10] did not find any associations between cleft type and dental anomalies either. "

    ABSTRACT: Background.Cleft lip and/or palate (CLP) is one of the most common types of craniofacial birth defects Objectives. The aim of the current study was to investigate the prevalence of dental anomalies in children with CLP and classify them according to the type of cleft. Material and Methods. This study consisted of 201 cleft patients including 131 males (mean age 12.3 ± 4 years) and 70 females (mean age of 12.6 ± 3.9 years). Dental anomalies including rotation, enamel opacity and hypopla-sia, and shape malformation of central and lateral incisors were recorded. T-test and chi-square test were used for assessment of the data. Results. Central incisor rotation was the most frequent anomaly observed. 57.2% of all the patients had central incisor rotation while only 15.4% of them had lateral incisor rotation. Chi square test showed that no specific association existed between anomalies and type of cleft. Enamel opacity and hypoplasia of central incisor was recorded in 40.3% and 35.8 of the patients respectively. 16.4% of the patients had peg shaped lateral incisors. Conclusions. Vast majority of cleft lip and or plate patients had at least one dental anomaly and most of the dental anomalies were observed at the side of cleft. However, no association could be found between the type of cleft and dental anomalies.

    • "Some craniofacial problems like cleft lip and palate may be associated with congenitally missing teeth, the rates of anterior missing teeth on the cleft side varied between 70.8% and 97.1%, depending on cleft type. Different rates of agenesis can be related to the severity of the cleft phenotype, which has been shown to have a correlation with the number of affected teeth.[6] "

    ABSTRACT: Objective: The aims of this study were to determine the prevalence of hypodontia in the permanent dentition in a sample of Sudanese patients who sought orthodontic treatment and to compare the results with the reported findings of other populations. Materials and Methods: Orthodontic files including orthopantomographs of 1069 patients (760 females and 309 males - more than 8 years old) were examined and inspected for evidence of hypodontia. Results: The prevalence of hypodontia of the present sample was 5.1%. Hypodontia was found considerably more frequently in the mandible than in the maxilla. The distribution of missing teeth was noticed in the left side more than in the right side. The most frequently missing teeth were the maxillary lateral incisors, followed by the mandibular second premolars, maxillary second premolars and mandibular left lateral incisor. The majority of patients had two or three teeth missing, but rarely more than 5 teeth missing. Conclusions: The prevalence of hypodontia of this study was within the range of that reported in the literature. The incidence of hypodontia in the anterior segment requires great need for orthodontic and prosthodontic treatment. With early detection of hypodontia, alternative treatment modalities can be planned and performed with a multidisciplinary team approach restoring the esthetic and function.
