Objective: To evaluate the prevalence of dental caries in patients with cleft lip and/or palate and their cleft-free sibling controls. Methods: The two subject groups (patient and control) comprised 106 participants. The former group consisted of 53 patients with cleft lip and/or palate, aged 12 to 29 years, who visited the Oral and Maxillofacial Surgery Hospital at Damascus University of Syria. The control group consisted of the patients’ siblings who had no clefts, and they were sex matched to the patient group. Dental caries were examined clinically and were reported using the decayed, missing, and filled permanent teeth (DMFT) index. The DMFT scores were compared between the two groups. Results: The author found an overall association of dental caries with the presence of cleft lip and/or palate (odds ratio  =  2.52; 95% confidence interval  =  1.389–4.574; p < .05). The DMFT index scores were proportionally higher in patients with cleft lip and/or palate compared with the control group (p < .001). Conclusion: Subjects with cleft lip and palate are susceptible to dental caries independently of socioeconomic status.

Objective: Children with cleft lip and palate are reported to be commonly associated with higher prevalence of dental anomalies such as hypodontia, supernumeraries, and abnormalities in tooth size, shape, and position. This study investigated the prevalence of dental anomalies in a longitudinal cohort of children with unilateral cleft lip and palate (UCLP). Design: The study was a retrospective analysis of radiographs, study models, and treatment notes. Patients: Sixty patients with repaired UCLP aged 13 years old with complete dental records dating from 5 years of age were included. Methods: Study casts, dental panoramic, anterior maxillary occlusal, and periapical radiographs of the patients were examined for cleft-sidedness, congenitally missing permanent teeth, supernumerary teeth, microdontic, and macrodontic teeth in the anterior maxillary region, presence of malformed permanent cleft-sided lateral incisor and its morphology (peg-shaped, conical shaped, canine-formed), positions of the permanent lateral incisors relative to the cleft side and presence of rotated cleft-sided central incisors. Results: Of the 60 patients studied, 63.3% had hypodontia, 21.7% had supernumerary teeth, 69.6% had microdontia, and 12.5% had macrodontia. All of the cleft-sided permanent lateral incisors had associated anomalies, with a large proportion (43.1%) missing; and when present in 31 subjects, the majority (90.3%) was positioned distal to the cleft. Most of the cleft-sided permanent central incisors were rotated if present, and prevalent at 86.7%. Conclusion: A high prevalence of dental anomalies was observed in this sample of children with UCLP.

Maxillary lateral incisors on the alveolar cleft were investigated in 431 cleft children registered in the Department of Orthodontics, Kyushu University Dental Hospital. The majority of primary maxillary lateral incisors were located on the distal side of the alveolar cleft in both unilateral cleft lip and alveolus (UCLA) and unilateral cleft lip and palate (UCLP) subjects. Permanent teeth in UCLA tend to be located distally, but in UCLP they tend to be congenially absent (p < .01). The majority of primary teeth had normal shapes; the majority of permanent teeth were of intermediate type or were missing congenially. One third of the UCLA and one half of the UCLP subjects who had primary maxillary lateral incisors were not followed by permanent replacements. The location of the majority of permanent maxillary lateral incisors tallied with that of the primary ones except in four UCLA, ten UCLP, and two bilateral cleft lip and palate (BCLP) subjects. Four UCLA and ten UCLP subjects who had primary lateral incisors on the distal side were followed by their permanent successors on the mesial side. Three UCLP and one BCLP subjects had permanent maxillary lateral incisors even though they had no temporary predecessors.

The incidence of dental abnormalities in the cleft lip and palate population has been reported to be much higher than in the normal population. The role of genes in the production of a cleft lip and palate, and dental anomalies is thought to be complex, with autosomal dominant, recessive, and x-linked genes all playing a role. Noncleft parents can carry some of the cleft lip and palate genes, which produce clinically subtle manifestations in their facial skeleton. The purpose of this study was to look for evidence of increased dental anomalies in the non-cleft parents of cleft lip and palate children. The dentitions of the parents of 60 children with different types of cleft lip and palate were examined prospectively to see whether or not they exhibited features found more readily in the cleft lip and palate rather than did the normal population. Their dentitions were studied to record the following dental features: congenitally missing teeth, supernumerary teeth, or morphologic changes of the crowns of the permanent teeth. The number and position of any frenal attachments were also recorded. The results of this study did not show any differences in incidence of dental anomalies from the noncleft population. There was no evidence to support the hypothesis that congenital absence of lateral incisors is a microform of cleft lip and palate. Further, these results also failed to reveal any consistent pattern in the number and position of frenal attachments.

Objective To establish the chronology and sequence of eruption of the permanent teeth in subjects with complete unilateral cleft lip and palate. Design Cross-sectional. Data on children presenting complete cleft lip and palate were evaluated. Setting The study was carried out at the Hospital for Rehabilitation of Craniofacial Anomalies, Bauru, Sao Paulo, Brazil. Sample The sample comprised 477 patients with complete unilateral cleft lip and palate, aged 5 to 14 years. Of these patients, 166 were girls and 311 were boys. Results The girls presented, for all maxillary and mandibular teeth, a smaller mean age of eruption than the boys. The maxillary lateral incisor and cuspid adjacent to the cleft presented significantly higher mean ages of eruption than their homologous teeth on the noncleft side.

ABSTRACT Introduction: Supernumerary teeth in cases of cleft lip and palate do not result from the division of normal germs before the formation of hard tissue. Deciduous and permanent teeth odontogenesis begins after the face has formed, either with or without the cleft. Discussion: The most acceptable hypothesis to enable understanding of the presence of supernumerary teeth on one or both sides of the cleft palate is hyperactivity of the dental lamina in its walls. This hyperactivity, with the formation of more tooth germs, must be attributed to mediators and genes related to tooth formation, under strong influence of local epigenetic factors, whose developmental environment was affected by the presence of the cleft. Conclusion: The current concepts of embryology no longer support the fusion of embryonic processes for the formation of the face, but rather the leveling of the grooves between them. All human teeth have a dual embryonic origin, as they are composed of ectoderm and mesenchyme/ectomesenchyme, but this does not make it easy for them to be duplicated to form supernumerary teeth.

Abstract Tooth size, being the effect of interaction of genetic and prenatal factors, could be of importance in interpreting the multifactor causes of cleft lip/palate. Publications indicating decreased tooth parameters, no dental differences, or larger dimensions of teeth in cleft lip/palate patients. Researchers report mostly mesiodistal (MD) measurements of maxillary (affected) teeth. There is a lack of data for buccolingual (BL) diameters. Both MD and BL parameters have influence on the planning and performance of orthodontic treatment. The aim of this paper was to assess differences in mesiodistal and buccolingual tooth dimensions in Polish children with unilateral cleft lip and palate (UCLP) in comparison to patients without oral clefts. A total of 1883 permanent teeth, 1182 teeth of UCLP patients and 701 teeth of healthy participants were analyzed. Tooth diameters were performed using an orthodontic cast of dentition with a digital odontometer. The greatest anomalies were found in both maxillary canines and consisted of their reduced mesiodistal dimension and increased buccolingual dimension, resulting in a pathologically high crown shape index (BL/MD). Conclusion can be drawn that unilateral cleft lip and palate is a condition that causes morphological disturbances of varying severity in most mandibular and maxillary teeth both on the cleft and non-cleft sides.

Objective: To retrospectively study the anterior maxilla of southern Chinese children with complete cleft lip and palate (CLP) for the prevalence of different kinds of dental anomalies, position and rotation of the teeth, and the asymmetry of dental development. Patients: 195 southern Chinese children with CLP aged between 3 and 17 years. Methods and Materials: Dental records and study casts were studied as were the radiographs from which the dental development was determined. Results: The tooth prevalence of cleft side permanent lateral incisor was 19.2% in unilateral CLP (UCLP) children and 20.5% in bilateral CLP (BCLP) children. The cleft side central incisors were rotated in 78.1% and 95.9% of the teeth in UCLP and BCLP children, respectively. Of the permanent canines, 43.4% were positioned mesially on the cleft side in UCLP children, while for BCLP children 69.7% of the teeth were in a normal position. In addition, the mesially positioned canines were often associated with an absence of the permanent lateral incisor while the distally positioned canines were always associated with the presence of supernumeraries in the cleft region. The permanent teeth on the cleft side showed significantly delayed development compared with their antimeres on the noncleft side; however, the delayed permanent lateral incisors did complete their formation normally. Conclusion: This group of Chinese children with CLP demonstrated statistically significant higher prevalences of hypodontia, microdontia, and delayed dental development on the cleft side than the noncleft side.
