Objective To determine in complete unilateral cleft lip and palate (UCLP) subjects the characteristics (location, shape) of the cleft-side lateral incisor. The presence of a supernumerary tooth at the cleft side and the prevalence of hypodontia outside the cleft area were evaluated. A comparison was made of the shape of the cleft side lateral incisor to its contralateral incisor. Setting Hospital for Rehabilitation of Craniofacial Anomalies (HRCA), Sao Paulo, Brazil. Patients Orthopantomograms of 203 subjects with UCLP and without syndromes were chronologically selected from the HRCA data bank, within an age range of 5 to 10 years. Outcome Measure Orthopantomograms were analyzed by the same observer according to established criteria. Results There were no statistically significant differences between sexes for any of the criteria studied. The cleft-side lateral incisor was present in 50.2%, and it was more commonly located at the distal side (76.5%). The congenital absence of the cleft-side lateral incisor was observed in 49.8% of the sample, and its antimere was congenitally missing in 10.9%, this difference being statistically significant. The most commonly missing tooth outside the cleft area was the maxillary second premolar. Conclusions The high prevalence of hypodontia of the permanent lateral incisor in the cleft side showed that the cleft could play an important role in this absence. There were different patterns for the presence of the cleft-side lateral incisor.

Research Analysis

Introduction:Cleft lip and palate are craniofacial anomalies highly prevalent in the overall population. In oral clefts involving the alveolar ridge, variations of number, shape, size and position are observed in maxillary lateral incisors. The objective of this manuscript is to elucidate the embryonic origin of maxillary lateral incisors in order to understand the etiology of these variations.Contextualization: The hypothesis that orofacial clefts would split maxillary lateral incisor buds has been previously reported. However, recent studies showed that maxillary lateral incisors have dual embryonic origin, being partially formed by both the medial nasal process and the maxillary process. In other words, the mesial half of the lateral incisor seems to come from the medial nasal process while the distal half of the lateral incisor originates from the maxillary process. In cleft patients, these processes do not fuse, which results in different numerical and positional patterns for lateral incisors relating to the alveolar cleft. In addition to these considerations, this study proposes a nomenclature for maxillary lateral incisors in patients with cleft lip and palate, based on embryology and lateral incisors position in relation to the alveolar cleft.Conclusion:Embryological knowledge on the dual origin of maxillary lateral incisors and the use of a proper nomenclature for their numerical and positional variations renders appropriate communication among professionals and treatment planning easier, in addition to standardizing research analysis.

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.

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.

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.

(WHO meetings on International Collaborative Research on Craniofacial Anomalies).One of the most common congenital anomaly we come across is the Cleft Lip and palate where affected children suffer from range of functional as well as aesthetic problems. Cleft lip and palate is a multifunctional disease associated with environmental factors. Management of cleft is a complex procedure and demands co-operation among experts from different fields. Clinical treatment procedure extends from beginning of birth, to achieving skeletal maturity effectively.
