Objective: To evaluate the dental characteristics of patients subjected to a protocol that included early secondary gingivoalveoloplasty (ESGAP). Design: Panoramic radiographs of 87 patients with unilateral cleft lip and palate (UCLP) and 29 with bilateral cleft lip and palate (BCLP) were evaluated. Missing and supernumerary teeth were also quantified on the cleft and noncleft side and in the maxilla and mandible. Crown and root malformations and tooth rotations were quantified. A subsample in permanent dentition was extrapolated to analyze canine eruption patterns. Results: A total of 48.8% of the UCLP patients presented with missing permanent lateral incisors in the cleft area and 6.1% contralaterally. A total of 4.9% presented with missing second maxillary premolars on the cleft site and 1.2% contralaterally. A total of 7.3% presented with supernumerary lateral incisors, and 45% of the BCLP cleft sites presented with missing lateral incisors, while 25% of the cleft sites presented second maxillary premolars agenesis. Five percent of the cleft sites presented with supernumerary lateral incisors. Evaluation of the subsample in permanent dentition showed that 15.5% had a canine retention and 4.4% of the canines had to be surgically exposed. A significant association was observed between canine inclination and retention but not with absence of the lateral incisor. Conclusions: The frequency of dental anomalies in this sample was similar to other cleft populations. As surgical trauma has been suggested to damage forming teeth, the results of this study indicated that ESGAP has no detrimental influence on subsequent dental development.

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: This study aimed to determine the correlations between the craniofacial morphology and pharyngeal airway volume in patients with complete bilateral cleft lip and palate (BCLP). Design: Retrospective study. Setting: Tertiary hospital. Participants: Twenty-seven patients with complete BCLP and 27 class I control patients, aged 10 to 14 years. Main Outcome Measure: The pharyngeal airway volume and craniofacial morphology were evaluated using cone-beam computed tomography. Measurements were compared between groups and any correlations were identified. Results: A significantly smaller total pharyngeal airway volume (TPV), oropharyngeal airway volume, and upper (UOPV) and lower (LOPV) oropharyngeal airway volume were found in patients with BCLP than in class I control patients, with no difference in the nasopharyngeal volume between groups. Furthermore, the craniofacial morphology measurements of N-Me, S-Go, Or-C, Ptm-C, Me-C, Co-Go, Go-Me, Ptm-Or, N-S-Ar, and Ar-Go-Me significantly differed between the BCLP and control groups (all P < .05). Multiple regression analysis indicated that Ptm-C and Me-C; Ptm-C, Or-C, and Me-C; and Me-C explained 20.3%, 38.9%, and 17.1% of the variations in TPV ( P = .025), UOPV ( P = .002), and LOPV ( P = .018), respectively. Conclusions: Total pharyngeal airway volume, TPV, OPV, UOPV, and LOPV were significantly smaller in patients with BCLP than in class I controls. In patients with BCLP, the maxilla showed inhibited sagittal development and a retrograde position; moreover, the pharyngeal airway volume was weakly associated with the position of the maxilla and mandible relative to the coronal plane.

Nonsyndromic cleft lip and/or palate (NSCL/P) are the most common congenital anomalies of the face. Dental abnormalities located inside and outside the cleft region are the most frequent dental characteristics found in these individuals. The aim of this paper is to review the literature on dental abnormalities associated with NSCL/P. A search for articles was conducted on electronic databases such as Medline, Lilacs and PubMed. According to the literature, dental abnormalities were more common in permanent dentition. Agenesis and supernumerary teeth showed the highest prevalence. The upper lateral incisor was the most affected teeth by agenesis, supernumerary teeth and microdontia. The teeth located closest to the cleft were more susceptible to defects. The presence of dental anomalies outside the cleft region suggests the presence of genetic events involved in both odontogenesis and craniofacial formation.

Objective: The aim of this study was to use dental development as a tool to subphenotype oral clefts and investigate the association of MMP2 with dentin-pulp complex anomalies, in order to identify dental anomalies that are a part of a “cleft syndrome.” Design: Two hundred and ninety individuals born with cleft lip and palate were evaluated and several clinical features, such as cleft completeness or incompleteness, laterality, and presence of dental anomalies were used to assess each individual’s cleft status. We tested for overrepresentation of MMP2 single nucleotide polymorphism rs9923304 alleles depending on individuals having certain dental anomalies. Chi-square and Fisher exact tests were used in all comparisons (α = .05). Results: All individuals studied had at least one dental anomaly outside the cleft area. Significant differences between individuals born with clefts with and without talon cusp ( P = .04) were observed for the frequency of the MMP2 less common allele. Conclusion: All individuals born with cleft lip and palate had alterations of the dentition, and a quarter to half of the individuals had alterations of the internal anatomy of their teeth, which further indicates that dental anomalies can be considered as an extended phenotype for clefts. MMP2 was associated with talon cusp in individuals born with oral clefts.

Supernumerary teeth occur in approximately 1–2% of the population. Multiple supernumerary teeth are less common and usually associated with certain medical conditions. Most supernumeraries develop at a similar time to the normal series; however, this article describes the presentation and management of three patients who developed multiple supernumerary teeth during active orthodontic treatment in the permanent dentition. CPD/Clinical Relevance: These cases show development of multiple supernumerary teeth in the both the maxilla and mandible demonstrating a variation of types and effects on the dentition. In particular, multiple supernumeraries in the anterior maxilla and supplementals in the mandibular premolar regions highlight that supernumerary teeth may develop a considerable time after the development of the permanent dentition. These can develop during orthodontic treatment. Consideration, therefore, may be given to closer and longer monitoring of dental development in patients with multiple supernumerary teeth.

ABSTRACT Objective: The purpose of this paper was to describe the prevalence and type of dental anomalies in the primary and permanent dentition in children with a cleft condition at Princess Margaret Hospital in Perth, Western Australia. Materials and Methods: The details of 162 current dental patients extracted from the main dental database through their year of birth for the period 1998–2001 were selected consecutively. Dental records and X-rays were examined by one examiner (WN) and verified by a second examiner (RB) to determine dental development. The mean age of the subjects was 10.8 years with equal numbers of males and females. Subjects were further divided into cleft type; unilateral cleft lip (UCL) and palate, bilateral cleft lip (BCL) and palate, UCL, BCL, and cleft palate. Results: One hundred sixty-two subjects were grouped into 21 categories of anomaly or abnormality. Prevalence rates for the categories were calculated for the overall group and for gender and cleft type. Conclusion: Overall, 94% of patients were found to have at least one dental anomaly, with fifty-six (34%) patients having more than one anomaly or abnormality.

Objective The aim is to survey primary and permanent dental anomalies: hypodontia, microdontia, a supernumerary tooth, and fused teeth in patients with cleft lip and/or palate. Design Retrospective longitudinal study Subjects The subjects were selected from all 1724 patients with cleft lip and/or palate who were registered at the orthodontic clinic of Kyushu University Hospital, Fukuoka, Japan, from 1970 to 2009. Finally, 994 subjects were evaluated for primary dentition, 1352 for permanent dentition, and 871 for the longitudinal changes from primary to permanent dentition. Methods The prevalence of dental anomalies was compared for each tooth type, among various cleft types, between males and females, and between the alveolar cleft area and the noncleft area. Results The prevalence of hypodontia was 16.2% for primary dentition and 52.7% for permanent dentition in the subjects with cleft lip and/or palate. Hypodontia increased with the severity of the cleft type. Multiple hypodontia was found more frequently in the subjects with bilateral cleft lip and palate and the subjects with unilateral cleft lip and palate. Microformed lateral incisors were found in 22.7% of permanent lateral incisors but not in primary dentition. Supernumerary teeth were found in 17.7% of the subjects with cleft lip and/or palate for primary maxillary dentition and in 5.7% for permanent maxillary dentition. Conclusion The prevalence of hypodontia was greater in permanent dentition than in primary dentition; although, it was not much different between males and females or between the right and left sides. The prevalence of dental anomalies was significantly different among four groups by cleft type: cleft lip, cleft lip and alveolus, cleft lip and palate, and cleft palate.

Summary Background Children born with unilateral cleft lip and palate (UCLP) are reported to display several dental anomalies including agenesis, supernumeraries, as well as variations in dental size, shape, and path of eruption. The extensive sample of individuals with UCLP included in the Scandcleft randomized control trials offers the opportunity to study more rare conditions, which is seldom possible with limited samples. Objectives The aim was to study dental anomalies at 8 years of age in children born with UCLP included in the Scandcleft randomized control trials. Methods Panoramic and intraoral radiographs from 425 individuals (279 males and 146 females) with a mean age of 8.1 years were assessed by four orthodontists regarding dental anomalies. Results Agenesis was found in 52.5 per cent and supernumerary teeth in 16.9 per cent of the participants. The cleft lateral was missing in 43.8 per cent and was found peg shaped in 44.7 per cent. The distribution of ectopic eruption was 14.6 per cent, mainly affecting maxillary first molars, while transposition was found in 3.4 per cent of the individuals. In addition, infraocclusion of one or several primary molars was registered in 7.2 per cent of the participants. Conclusion We conclude that 8-year-old children born with UCLP display multiple dental anomalies. The Scandcleft sample allowed rarely studied conditions such as infraocclusion of primary molars and transposition to be studied in children born with UCLP. Trial registration ISRCTN29932826.

Objectives: To assess the risk of dental anomaly presentation in permanent teeth in a group of Colombian children with nonsyndromic cleft lip and palate (NSCLP) and to determine the frequency of the anomalies according to the cleft type. Methods: An analytical matched case–control study was conducted with 210 controls and 210 patients with NSCLP. The patients were classified into 3 groups: complete right unilateral cleft lip and palate (RCLP), complete left unilateral cleft lip and palate (LCLP), and complete bilateral cleft lip and palate (BCLP). Univariate and multivariate Poisson regression models were used to analyze paired samples (Bonferroni adjustment, P ≤ .002). Results: A high risk of finding agenesis of the maxillary lateral incisors, supernumerary teeth, microdontia of the maxillary lateral incisors, and rotation of the maxillary central incisors adjacent to the cleft ( P < .0001) was observed in the patients with NSCLP. One or more dental anomalies were found in 98% of patients with BCLP, in 96% of those with LCLP, and in 87% of those with RCLP. Most of the anomalies were located on the cleft area. The incidence relative risk (IRR) of anomalies was highest in patients with BCLP (IRR: 10.5; 95% confidence interval [CI]: 6.76-16.3), followed by in those with LCLP (IRR: 8.51; 95% CI: 5.64-12.8). Conclusions: Most dental anomalies were found in the cleft area; this was expected because the cleft area was the most affected in the patients included in this study.
