Abstract
To investigate the distribution of dental anomalies between non-syndromic orofacial cleft patients and their association with the cleft type and gender. Retrospective cross-sectional study involving examination of intraoral dental records and radiographs. 300 non-syndromic orofacial cleft patients included (161 males and 139 females, mean age: 10.23 ± 2.3 years). Variables analyzed: tooth agenesis, microdontia, and supernumerary teeth. Data analysis: Chi-square and Fisher's exact tests to investigate the correlation between dental anomalies, cleft type, and gender. Agenesis occurred in 66% of the subjects, supernumerary teeth in 19.6%, and microdontia in 18.3%. In females with unilateral left cleft lip and palate (CLP), agenesis was significantly higher compared to males. Both genders presented significant agenesis of maxillary lateral incisors and right central incisor. Significant agenesis of central incisor, canine and second premolar on the upper left side and lower second premolars were observed only in males, with significant microdontia for maxillary lateral incisors and left central incisor. Significant agenesis of maxillary first premolars was seen only in females. Agenesis in maxillary quadrants was significant for patients with unilateral right and left CLP, and bilateral CLP. In mandibular quadrants, agenesis was substantially higher for patients with isolated CP. Results suggest that tooth agenesis and microdontia might not be directly associated with the cleft area's anatomical irregularity but are affected by gender and other genetic factors that regulate the development of the anomaly and the orofacial clefting mutually.

Abstract
OBJECTIVE To evaluate the association between orofacial clefts (OFC) and tooth abnormalities (TA). METHODS We searched PubMed, Scopus, Web of Science, Cochrane Library, LILACS, and BBO, and in the gray literature and selected observational studies that evaluated the association between TA and OFC. The risk of bias was analyzed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed comparing the presence and absence of OFC, cleft type-cleft palate (CP) and cleft lip with or without palate (CL/P)-and cleft laterality-unilateral and bilateral. The certainty of evidence was evaluated using the GRADE approach. RESULTS A total of 99 studies were included in the qualitative analysis, and 37 were included in the meta-analysis. Only four studies were classified as low risk of bias. Significant associations were observed between the presence of OFC and tooth agenesis (OR = 19.46; 95%CI = 4.99-75.96), supernumerary teeth (OR = 4.04; 95%CI = 1.26-12.99), developmental defects of enamel (OR = 3.15; 95%CI = 1.28-7.80), microdontia (OR = 15.57; 95%CI = 1.06-228.51), and taurodontism (OR = 1.74; 95%CI = 1.74-2.86). Individuals with CP had a lower frequency of supernumerary teeth (OR = 0.22; 95%CI = 0.08-0.64), peg-shaped tooth (OR = 0.31; 95%CI = 0.12-0.80), and morphological TA (OR = 0.13; 95%CI = 0.04-0.45) than individuals with CL/P. No TA was significantly associated with cleft laterality (p > 0.05). The quality of the evidence was very low in all analyses. CONCLUSION Individuals with OFC had a higher frequency of TA than those without OFC. Individuals with CP had a lower frequency of TA than individuals with CL/P. No TA was associated to cleft laterality. CLINICAL RELEVANCE Help to identify the treatment needs of individuals affected by OFC, improving the services provided to this population.

Abstract
Background and objective Quality-of-life measures have been expanded to help in assessing the physical and psychosocial effects of oral health. Although, in the case of children undergoing oral surgery, the oro-facial status is generally measured by studies, it is essential to carry out investigations into the level of quality of life (QoL) after surgery to assess the actual effect of these surgeries on children’s lives. Hence, our study is aimed at evaluating the QoL in these children. Methods The study was performed using qualitative content analysis method. Eighteen caregivers of 4–6 year old children with a history of unilateral cleft lip and palate participated in in-depth interviews about the children’s experiences with different problems affecting their daily lives. The results were divided into codes, sub-categories and categories through an inductive process in which the researchers moved from the specific to the general. Result A number of problems were identified, particularly insufficient functional and socio-emotional well-being including, difficulty in eating and speaking, dento-facial problems, shame, anxiety, insufficient peer interaction and dissatisfaction with their own appearance. Conclusion The most critical problems derived from the participants’ experiences were insufficient functional and socio-emotional well-being that contributed to the reduced QoL among these children. Long term multidisciplinary interventional strategies such as psycho-social supportive programs are required to improve the QoL of these children. These interventions should be considered from the early stages of treatment, or even early stages of diagnosis.

Abstract
Objective The objective of this study was to compare the cephalometric skeletal and dental characteristics of unilateral complete cleft lip and palate (UCCLP) subjects with and without missing teeth. Design A retrospective records review was conducted for patients who are being treated at the cleft lip and palate (CLP) clinics in the College of Dentistry. Methods Ninety-six consecutive records of non-syndromic UCCLP subjects were recruited (33 subjects without missing teeth, 50 subjects with only one missing tooth, and 13 subjects with two or more missing teeth). Skeletal and dental characteristics were assessed using lateral cephalometric radiographs in UCCLP subjects with missing teeth and compared to the group with no missing teeth. A total of 25 linear and angular measurements were analyzed and compared between the sample groups. Results Of the dental variables tested, overjet was significantly different between the three groups. The UCCLP subjects with multiple missing teeth had the smallest overjet (–3.89±2.75 mm; P=0.015) among the three groups. None of the skeletal characteristics reached statistical significance. Conclusion Missing teeth influence the dental but not skeletal characteristics of UCCLP. Overjet is significantly reduced in UCCLP subjects with multiple missing teeth. Future studies with larger sample sizes are warranted.

Abstract
Oral clefts play an essential role in disturbed odontogenesis of the deciduous and permanent dentition, yet little is known about this relationship. We investigated, within the categories cleft lip with or without alveolus (CL ± A) and cleft lip, alveolus and palate (CLAP), whether different CL subphenotypes based on morphological severity of the cleft show different dentition patterns and whether a more detailed subdivision of the incomplete CL has clinical relevance. In this retrospective study, 345 children with nonsyndromic unilateral CL ± A and CLAP from the Dutch Association for Cleft Palate and Craniofacial Anomalies (NVSCA) registry were included to assess the association between the CL subphenotypes and lateral incisor patterns. Five different deciduous and permanent patterns of the lateral incisor were distinguished: located in normal position (pattern z/Z), in the anterior segment (pattern x/X) or in the posterior segment of the cleft (pattern y/Y), one in each segment of the cleft (pattern xy/XY), and agenesis of the lateral incisor (pattern ab/AB). Analyses were performed by using multinomial logistic regression models. Children born with a vermillion notch or a one-third to two-thirds CL were most likely to have a deciduous pattern x and a permanent pattern X, while children born with a two-thirds to subtotal CL were most likely to have deciduous pattern xy and a permanent pattern X compared to children with a complete CL that predominantly had deciduous pattern y and a permanent pattern AB. Based on the relationship of the CL morphology with the deciduous dentition, subdivision of the CL morphology into vermillion notch to two-thirds CL, two-thirds to subtotal CL, and complete CL appears to be an optimal subdivision. Our results indicate that a more detailed subdivision of the CL has clinical relevance and that critical factors in the pathogenesis of the CL are also critical for the odontogenesis.

A cross-sectional analysis of the prevalence of tooth agenesis and structural dental anomalies in association with cleft type in non-syndromic oral cleft patients. Prog Orthod 2017; 18:20.

Abstract
Background The aim of this study was to investigate the prevalence of tooth agenesis, microdontia, and tooth malformation among non-syndromic oral cleft patients and their potential association with cleft type and gender. Methods Intraoral records and radiographs of 154 patients (97 males and 57 females) were examined. The variables assessed were tooth agenesis, microdontia, dental malformations, and cleft types. The statistics included chi-square and Fisher’s exact tests as well as logistic regression to assess any mutual effects of gender and cleft type on the dental variables. Results Tooth agenesis occurred in 50% of the sample and microdontia in 18%. Non-statistically significant odds ratios for the association of gender and cleft type with tooth agenesis were obtained. Tooth agenesis was substantially higher at the unilateral right CL + P and the bilateral CL + P in quadrant 1 and at the unilateral left CL + P and bilateral CL + P in quadrant 2. It was also higher, at the isolated cleft palate (CP) in quadrants 3 and 4. These results were attributed to teeth 22 (31.8%) and 12 (21.6%) in the maxilla and to teeth 35 (6.1%) and 45 (5.4%) in the mandible. In unilateral CL + P patients, the cleft quadrant that presented tooth agenesis was associated with the side of the cleft. Conclusions Interdisciplinary treatment of the oral cleft patients should take into consideration the high prevalence of tooth agenesis and their association with the different cleft types. The most frequently affected teeth by cleft are by far the upper lateral incisors. Results indicate that tooth agenesis appears to be a genetically controlled anomaly related to the orofacial cleft development through various genetic links and not caused by the cleft disruptive process.

Abstract
Objectives Partial tooth agenesis is frequently observed in Robin sequence. Tooth anomalies are increasingly considered as an extended phenotype of the cleft palate population. The study objective was to compare the prevalence and patterns of tooth agenesis in a group of patients with non-syndromic Robin sequence (ns-RS) and a group with non-syndromic cleft palate (ns-CP). Materials and methods The panoramic radiographs of 115 ns-RS and 191 ns-CP patients were assessed for agenesis of the permanent dentition (excluding third molars) and the patterns recorded using the Tooth Agenesis Code. Results Partial tooth agenesis was observed in 47.8% of ns-RS and 29.8% of ns-CP patients with a greater prevalence in the mandibula than in the maxilla, particularly in ns-RS. The teeth most frequently absent in both groups were the mandibular second premolars and maxillary lateral incisors. Tooth agenesis was bilateral in two-thirds of affected ns-RS patients and one-half of ns-CP patients. In ns-RS, bilateral agenesis of the mandibular second premolars was more frequently observed in female than that in male patients. Completely symmetrical patterns of hypodontia were found in around 45% of ns-RS patients with tooth agenesis compared to 35% in ns-CP. No association was found between the extent of the palatal cleft and the severity of hypodontia. Conclusion Tooth agenesis is more prevalent in ns-RS than that in ns-CP, demonstrates a much greater predilection for the mandible in ns-RS, and bears no relation to the extent of the palatal cleft. Clinical relevance When compared to ns-CP, additional developmental disturbances are likely involved in the etiology of tooth agenesis in ns-RS. Future research could help identify the underlying genetic traits and aid in classifying patients in those with and without expected tooth agenesis in order to facilitate orthodontic management strategies.

Abstract
Background Cleft defects are one of the most frequent birth-deformities of the orofacial region and they are commonly associated with anomalies of the tooth structure, size, shape, formation, eruption, and tooth number. The aim of our study was to evaluate the prevalence, distribution, and potential association of combined hypodontia in cleft-affected patients with regard to all types of teeth in both jaws in the permanent dentition. Material/Methods This retrospective radiographic analysis included patients with various types of clefts treated orthodontically in the Department of Orofacial Orthopedics and Orthodontics at Heim Pàl Children’s Hospital, Budapest. There were 150 patients (84 males, 66 females) with non-syndromic unilateral (UCLP; n=120 patients) or bilateral (BCLP; n=30 patients) cleft formation (lip, alveolus and palate) who met the inclusion criteria. Statistical analysis was performed using the chi-square test and Fisher’s exact test (significance level p<0.05). Results Hypodontia was significantly more frequent in patients with cleft-sided lateral incisor (104 patients, 69%), with a total of 235 missing teeth, followed by the second premolars of the upper and lower jaw. A significant correlation of congenital missing teeth was observed in left-sided clefts between the upper and lower second premolar in the cleft area. Conclusions Hypodontia inside and outside the cleft area was frequently observed. This should affect the therapy plans, especially if the cleft-sided premolar is also absent. Further comprehensive research including numerous random samples is necessary for better estimating other possible associations.

Abstract
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.

Abstract
Objective The aims of this study were to investigate the prevalence and distribution of dental anomalies in a group of Saudi subjects with cleft lip and palate (CLP), to examine potential sex-based associations of these anomalies, and to compare dental anomalies in Saudi subjects with CLP with published data from other population groups. Design This retrospective study involved the examination of pre-treatment records obtained from three CLP centers in Riyadh, Saudi Arabia, in February and March 2010. The pre-treatment records of 184 subjects with cleft lip and palate were identified and included in this study. Pre-treatment maxillary occlusal radiographs of the cleft region, panoramic radiographs, and orthodontic study models of subjects with CLP were analyzed for dental anomalies. Results Orthopantomographs and occlusal radiographs may not be reliable for the accurate evaluation of root malformation anomalies. A total of 265 dental anomalies were observed in the 184 study subjects. Hypodontia was observed most commonly (66.8%), followed by microdontia (45.6%), intra-oral ectopic eruption (12.5%), supernumerary teeth (12.5%), intra-nasal ectopic eruption (3.2), and macrodontia (3.2%). No gender difference in the prevalence of these anomalies was observed. Conclusions Dental anomalies were common in Saudi subjects with CLP type. This will complicate the health care required for the CL/P subjects. This study was conducted to epidemiologically explore the prevalence of dental anomalies among Saudi Arabian subjects with CLP.

Abstract
Background Cleft lip and/or palate is the most frequent congenital abnormality occurring in the craniofacial region and is often associated with numerous dental defects such as tooth agenesis, supernumerary teeth, microdontia, taurodontism, crown malformations, or delay in eruption. The prevalence of hypodontia in cleft-affected patients is much higher in comparison with a healthy population. The aim of this study was to evaluate the prevalence of second premolar hypodontia in patients with cleft lip and/or palate. Material/Methods We performed a retrospective, evaluation of panoramic radiographs and dental casts in the Department of Dentofacial Orthopeadics and Orthodontics, Wroclaw Medical University. Two independent observers evaluated the records of 469 patients with various types of clefts and analyzed dental casts and panoramic radiographs. Results 202 individuals met inclusion criteria. The sample comprised 120 UCLP patients, 38 BCLP patients, 28 CP patients, and 17 CLA patients. Hypodontia in the premolar region was observed in 39 individuals (19.3%). A total number of 58 second premolars were missing, of which 35 were maxillary second premolars (U5) and 23 were mandibular second premolars (L5). Conclusions Estimated hypodontia in the Polish CL/P sample was considerably higher than the hypodontia in permanent dentition reported for a European healthy population. The number of congenitally missing second premolars was higher in the maxillary arch than in the mandibular.

Abstract
Objective Many studies have demonstrated a high frequency of dental anomalies in patients with cleft lip and/or palate. Because dental anomalies may complicate dental treatment, we investigated the prevalence of dental anomalies in a group of Brazilian patients with nonsyndromic cleft lip and/or palate. Design, Participants, Setting Retrospective analysis was performed using clinical records of 296 patients aged between 12 and 30 years with repaired nonsyndromic cleft lip and/or palate without history of tooth extraction and orthodontic treatment. Associations between oral clefts and presence of dental anomalies outside the cleft area were investigated. Results Dental anomalies were identified in 39.9% of the nonsyndromic cleft lip and/or palate patients, and tooth agenesis (47.5%), impacted tooth (13.1%), and microdontia (12.7%) were the most common anomalies. Cleft lip patients were less affected by dental anomalies compared with cleft palate or cleft lip and palate patients ( p = .057). Specifically, patients with unilateral cleft lip and palate were significantly more affected by dental anomalies than those with bilateral cleft lip and palate ( p = .00002), and individuals with unilateral complete cleft lip and palate ( p = .002) and complete cleft palate ( p = .01) were significantly more affected by tooth agenesis than other cleft types. Agenesis of the premolars ( p = .043) and maxillary lateral incisors ( p = .03) were significantly more frequent in patients with unilateral complete cleft lip and palate. Conclusions The present study revealed a high frequency of dental anomalies in nonsyndromic cleft lip and/or palate patients and further demonstrated that patients with unilateral cleft lip and palate were frequently more affected by dental anomalies than those with bilateral cleft lip and palate. Moreover, our results demonstrate that dental anomalies should be considered during dental treatment planning for individuals affected by nonsyndromic cleft lip and/or palate.

Abstract
OBJECTIVE Individuals with oral clefts exhibit considerably more dental anomalies than do individuals without clefts. Our aim was to evaluate the prevalence of tooth agenesis in a sample composed of 124 children (81 boys and 43 girls, mean age 12.5 years) with clefts registered with the Cleft Palate Center in Strasbourg (France). DESIGN Cleft types and dental agenesis were assessed by clinical and radiographic examination. Cleft types were divided into four groups according to the clinical extent of the cleft (cleft lip only [CL, 12.9%], cleft lip and alveolus [CLA, 4%], cleft lip and palate [CLP, 49.2%], and cleft palate only [CP, 33.9%]). RESULTS Of the subjects 63% had evidence of hypodontia: maxillary lateral incisors (54%) and upper and lower premolars (32%) were the most common missing teeth. The number of dental ageneses associated with CP (54%) and CLP (79%) was significantly higher than that with CL (33%). All these anomalies were found in proportionately higher frequencies as the severity of the cleft increased, and we found left side predominance for hypodontia (p < .01) irrespective of cleft sidedness. CONCLUSIONS Both right-sided and left-sided clefts were more frequently correlated with left-sided dental agenesis. This left-sided prevalence suggests that common signaling malfunctions might be involved, both in dental development anomalies and cleft genesis.

Abstract
OBJECTIVE To determine the presence of specific patterns of dental defects in a group of individuals born with clefts. DESIGN Case-control. SETTING Nossa Senhora do Loreto Municipal Hospital and Federal University of Rio de Janeiro Pediatric Dentistry Clinics, Rio de Janeiro, Brazil. PATIENTS 642 radiographic and clinical records were evaluated for 321 cases and 321 controls. RESULTS Individuals born with clefts presented considerably more dental anomalies in comparison with controls (p = .0001). The most frequent was tooth agenesis (n = 53; p = .001), followed by supernumerary teeth (n = 14; p = .11) and tooth malposition (n = 11; p = .33). Regarding tooth agenesis, the upper lateral incisors were more frequently absent in the cleft group (31/86), and control individuals presented more agenesis of the mandibular second premolars (19/45). CONCLUSIONS The higher prevalence of dental anomalies, especially number anomalies, opposite the cleft area, in individuals born with cleft lip and/or palate is the most common associated dental anomaly outside the cleft area.

Abstract
OBJECTIVE To assess whether individuals born with nonsyndromic oral clefts display a higher frequency of dental anomalies. DESIGN A search of MEDLINE, BIREME, OVID ALL EMB Reviews, and The Cochrane Library was conducted. The methodologic quality of the papers selected was assessed and scored. Papers reporting observational controlled studies of nonsyndromic forms of oral cleft matched for dental anomalies in primary and/or permanent teeth were included without language restrictions. Eligible studies were scored as "A"-low risk of bias, "B"-moderate risk of bias, or "C"-high risk of bias and poor quality. Fixed and random effects models were used to aggregate individual odds ratios (OR) and to derive pooled estimates and 95% confidence intervals. RESULTS Six studies fulfilled our selection criteria and were included in the meta-analysis. Three distinct subgroup analyses were carried out in terms of dental anomalies. In the tooth agenesis meta-analysis, a random effects model was used because of heterogeneity and showed a significant association between tooth agenesis and oral clefts (OR = 12.31; 95% confidence interval [CI] = 3.75 to 40.36). In the remaining analyses, the fixed effects model revealed a positive association between supernumerary (OR = 4.99; 95% CI, 2.58 to 9.64) and crown morphologic abnormalities (OR = 5.69; 95% CI, 3.96 to 8.19) with oral clefts. Most included studies were of low to moderate quality. CONCLUSION Although general limitations in study design were observed, the evidence suggests that a higher number of dental anomalies in the permanent dentition are noted in individuals born with oral clefts.

Abstract
OBJECTIVE To evaluate the prevalence of dental abnormalities of the primary and permanent maxillary dentitions in children affected by unilateral (UCLP) and bilateral (BCLP) cleft of the lip and palate. METHODS One hundred and fifty-six Caucasian patients (64 females and 92 males) affected by non-syndromic UCLP or BLCP were selected. A control sample of 1000 subjects (482 males and 518 females) without CLP was selected. All comparisons were carried out by means of z-tests on proportions. RESULTS The prevalence rate for missing primary lateral incisors in UCLP subjects was 8.1% and it was 27.9% for the permanent lateral incisors. In BLCP subjects, the prevalence rates were 17% for the primary lateral incisors and 60% for the permanent lateral incisors. The second premolar was absent in 5.4% of UCLP subjects and in 8.8% in the BCLP sample. The statistical analysis revealed significant differences for the prevalence rates of all dental anomalies compared with the control group except for second premolar agenesis. CONCLUSIONS In both UCLP and BCLP subjects the most prevalent missing teeth were the lateral incisors. The dental anomalies occurred predominantly in the cleft area, thus suggesting that the effect of the cleft disturbance is more local than general on the dentition.

Abstract
OBJECTIVES The aim of this investigation was to study the epidemiology of the isolated soft tissue cleft lip (ICL) population and to evaluate the dental anomalies associated with permanent dentition. METHODS The study included 19 children aged 9-13 years presenting ICL selected from 657 cleft lip-affected patients treated during the last 10 years in two craniofacial centers. Only 17 patients could be included for dental anomaly evaluation: Hyperdontia, Hypodontia, Gemination, Talon tooth, Microdontia, and Macrodontia. These were compared with cleft lip and palate (CLP) and cleft lip and alveolus (CLA)-affected populations and with normal populations. RESULTS The prevalence of ICL was 2.8%. All types of tooth abnormalities were found to be higher and mainly significant for the cleft side of ICL compared with the normal population. On the side opposite the cleft, the prevalence of dental anomalies reduced toward the normal individuals and was not significantly different. The significant differences found between CLP, CLA, and ICL-affected populations were mostly depicted by lateral incisors and second pre-molar hypodontia. CONCLUSIONS Isolated cleft lip is a rare phenomenon among the spectrum of the cleft-affected population. The prevalence of the dental anomalies in ICL maintains the proportional trend according to clefting severity.

Abstract
Objective The aim of our study was to investigate radiographically the prevalence of dental anomalies in a group of Jordanian cleft lip and/or palate subjects. Design This is a retrospective review of panoramic radiographs of 78 subjects with cleft lip and/or palate that were evaluated from their file records and investigated for possible dental anomalies. Results Dental anomalies were found frequently in cleft lip and/or palate subjects. Missing teeth were found in 66.7% of the patients; the tooth most commonly missing was the maxillary lateral incisor. Supernumerary teeth were found in 16.7% of patients; 37% had microdontia; 70.5% had taurodontism; 30.8% had transposition and/or ectopic teeth; 19.2% had dilacerations; and 30.8% had hypoplastic teeth. There was no statistically significant difference in the above anomalies’ prevalence between males and females. However, it was found that subjects with bilateral cleft lip and/or palate had significantly more microdontia ( p = .005), dilaceration ( p = .002), and hypoplastic teeth ( p = .0001) than subjects with unilateral cleft lip and/or palate. Conclusions The prevalence of dental anomalies in cleft lip and/or palate patients was higher than what had been reported in the normal Jordanian population. This emphasizes the relation of cleft lip and/or palate to all dental anomalies studied. Although our study represents a thorough and complete description of dental anomalies present in a sample of cleft lip and/or palate subjects, larger samples are required to effectively determine the relationship of each dental anomaly with cleft type.

Abstract
OBJECTIVES X-linked hypohidrotic ectodermal dysplasia (XLHED) occurs in several species, including humans, mice, cattle and dogs. The orofacial manifestations of ectodermal dysplasia in humans and mice have been extensively studied, but documentation of dental abnormalities in dogs is lacking. The current study describes the results of clinical and radiographic examinations of XLHED-affected dogs and demonstrates profound similarities to findings of XLHED-affected humans. SETTING AND SAMPLE POPULATION Section of Medical Genetics at the University of Pennsylvania, School of Veterinary Medicine. Clinical and radiographic oral examinations were performed on 17 dogs with XLHED, three normal dogs, and two dogs heterozygous for XLHED. MATERIALS AND METHODS The prevalence and severity of orofacial and dental abnormalities were evaluated by means of a sedated examination, photographs, and full-mouth intraoral radiographs. RESULTS Crown and root abnormalities were common in dogs affected by XLHED, including hypodontia, oligodontia, conical crown shape, decreased number of cusps, decreased number of roots, and dilacerated roots. Persistent deciduous teeth were frequently encountered. Malocclusion was common, with Angle Class I mesioversion of the maxillary and/or mandibular canine teeth noted in 15 of 17 dogs. Angle Class III malocclusion (maxillary brachygnathism) was seen in one affected dog. CONCLUSION Dental abnormalities are common and severe in dogs with XLHED. Dental manifestations of canine XLHED share characteristics of brachyodont tooth type and diphyodont dentition, confirming this species to be an orthologous animal model for study of human disease.

Abstract
AIM This was to record the oral health profile and more specifically the prevalence of carious and hypoplastic lesions in children and adolescents with cleft lip and palate (CLP). STUDY DESIGN AND METHODS The study group consisted of 41 children and adolescents (4-18 years-old) with CLP group while a similar number of non-cleft persons (HLP) matched for sex, age and orthodontic treatment (75.6%), was used as the control group. Information regarding the oral health habits, medical and dental history were collected using a questionnaire. Stimulated saliva was collected to evaluate the flow rate and buffering capacity as well as the levels of mutans streptococci and lactobacilli using the chair-test CRT(R) (Ivoclar -Vivadent). Oral hygiene (OH) was assessed using the index of Silness and Loe [1964]. The prevalence of initial/white spot and cavitated carious lesions as well as hypoplasia was evaluated based on the criteria by ICDAS [2005] and Nyvad et al [2008] as well as Koch et al [1987] respectively. The statistical analysis was carried out using the t-test and the chi- square test. RESULTS Approximately half of the CLP and HLP subjects were brushing their teeth 2 x per day. Both groups reported an average of 3 main and 2 snack meals per day. Levels of mutans streptococci and lactobacilli as well as the quality of the saliva were similar for both groups. The plaque index score was significantly higher in the CLP than in the control group (p=0.0003). The prevalence of cavitated carious lesions was similar in both groups but that of the initial/white spot lesions, especially at the area of maxillary incisors, was higher in the CLP group (85%, p=0.000). CONCLUSIONS The increased numbers of initial/ white spot lesions combined with poor OH found in the CLP group predispose for an increased risk of further development to carious cavitated lesions. Taking into consideration that the majority of those patients were under orthodontic treatment, the application of an intensive individualized oral health preventive program, focused on remineralisation of the initial caries, is imperative.

Abstract
Dental agenesis is the most common developmental anomaly in humans and is frequently associated with several other oral abnormalities. Whereas the incidence of missing teeth may vary considerably depending on dentition, gender, and demographic or geographic profiles, distinct patterns of agenesis have been detected in the permanent dentition. These frequently involve the last teeth of a class to develop (I2, P2, M3) suggesting a possible link with evolutionary trends. Hypodontia can either occur as an isolated condition (non-syndromic hypodontia) involving one (80% of cases), a few (less than 10%) or many teeth (less than 1%), or can be associated with a systemic condition or syndrome (syndromic hypodontia), essentially reflecting the genetically and phenotypically heterogeneity of the condition. Based on our present knowledge of genes and transcription factors that are involved in tooth development, it is assumed that different phenotypic forms are caused by different genes involving different interacting molecular pathways, providing an explanation not only for the wide variety in agenesis patterns but also for associations of dental agenesis with other oral anomalies. At present, the list of genes involved in human non-syndromic hypodontia includes not only those encoding a signaling molecule (TGFA) and transcription factors (MSX1 and PAX9) that play critical roles during early craniofacial development, but also genes coding for a protein involved in canonical Wnt signaling (AXIN2), and a transmembrane receptor of fibroblast growth factors (FGFR1). Our objective was to review the current literature on the molecular mechanisms that are responsible for selective dental agenesis in humans and to present a detailed overview of syndromes with hypodontia and their causative genes. These new perspectives and future challenges in the field of identification of possible candidate genes involved in dental agenesis are discussed.

Abstract
OBJECTIVE To describe erupting maxillary canine positions in patients with bone-grafted alveolar clefts. SAMPLE The sample consisted of 101 cleft sites from patients with complete unilateral or bilateral cleft lip and palate who had early (< or =9 years) or late (>9 years) secondary alveolar bone grafts. METHODS Canine position was assessed using panoramic radiographs taken before and after alveolar bone grafts. Vertical canine positions were assessed using the long axis of the maxillary permanent canine relative to a 90 degrees vertical reference line. Lateral canine positions were defined using the relationship between the canine tip and the midplane of the lateral incisor root. Anomalous lateral incisors were recorded. Statistical analysis included Student's t tests and chi-square tests. RESULTS Patients with alveolar clefts had a 20-fold increased risk for canine impaction, based on erupting canine positions. Abnormal vertical canine positions decreased following early and late alveolar bone grafts (p < .05), whereas abnormal lateral canine positions increased following late alveolar bone grafts (p < .01). Of the cleft sites with altered canine positions, 61% also had a lateral incisor anomaly. Based on canine position, the non-cleft-side canine had the same risk for impaction as the cleft-side canine. CONCLUSIONS Patients with alveolar clefts have a significantly higher risk for canine impaction compared with patients without clefts. Timing of alveolar bone grafts and lateral incisor anomalies influenced the risk for canine impaction. An alveolar bone graft should be planned in accordance with maxillofacial development, including the eruption of teeth adjacent to the cleft.

Abstract
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.

Abstract
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.

Abstract
Individuals with clefts present considerably more dental anomalies than do individuals without clefts. We used dental development to subphenotype clefts with the goal of identifying cleft subgroups that could have specific genetic contributions. We examined 1000 individuals, 500 with clefts and 500 without. We used several clinical features, such as cleft completeness or incompleteness, laterality, and the presence of dental anomalies to assess each individual's cleft status. We performed chi-square and Fisher's exact tests to compare the frequencies of observed anomalies between individuals with and individuals without clefts, and among individuals with different cleft subphenotypes. Agenesis of the lateral incisor on the non-cleft side was the most remarkable observation, and may suggest that such cases could be considered incomplete forms of bilateral clefts of the lip.
