This study compares a subpopulation of persons with cleft lip/palate who have mental retardation (n = 56) to those with normal learning (n = 420), at a large university-based cleft-craniofacial center. Many of the patients Identified as having mental retardation in this sample have the diagnosis of isolated cleft palate (46.8%). Nearly half (46.3%) of the patients with mental retardation were found to have multiple anomalies, syndromes or associated medical findings. Common findings included cardiopulmonary defects, seizures, and deviations in head size. In this clinic population, mental retardation was found more commonly among African-American patients with clefts, than among Caucasian patients with clefts. Higher rates of facial disfiguration and impaired speech were found in patients with clefts and mental retardation. This research demonstrates that among a population of persons with cleft lip and/or cleft palate, there is a subpopulation of children who also have mental retardation. Craniofacial-cleft teams will need to develop strategies to address the special needs of this group of patients.

Orthodontic treatment in patients with orofacial cleft such as cleft lip and palate or isolated cleft palate is challenging, especially when the patients exhibit severe maxillary growth retardation. To correct this deficiency, maxillary expansion and protraction can be performed in the first phase of orthodontic treatment. However, in some cases, the malocclusion cannot be corrected by these procedures, and thus, skeletal discrepancy remains when the patients are adolescents. These remaining problems occasionally require various orthognathic treatments according to the degree of the discrepancy. Here, we describe one case of a female with isolated cleft palate and hand malformation who exhibited severe maxillary deficiency until her adolescence and was treated with multiple orthognathic surgeries, including surgically assisted maxillary expansion (surgically assisted rapid palatal expansion), LeFort I osteotomy, and bilateral sagittal split osteotomy in order to correct severe skeletal discrepancy and malocclusion. The treatment resulted in balanced facial appearance and mutually protected occlusion with good stability. The purpose of this case report is to show the orthodontic treatment outcome of 1 patient who exhibited isolated cleft palate and subsequent severe skeletal deformities and malocclusion which was treated by an orthodontic-surgical approach.

Objective: To report the patterns of cleft lip and/or cleft palate in Saudi Arabia from data collected at a tertiary care hospital. Design and Setting: King Faisal Specialist Hospital and Research Center, Riyadh. Patients: All the cleft lip and/or cleft palate patients registered in the Cleft Lip/Palate and Craniofacial Anomalies Registry from June 1999 to December 2005. Results: Retrospectively, 807 cases of cleft lip and/or palate were registered. There were 451 boys and 356 girls. Cleft lip and palate was more common (387) than isolated cleft palate (294) and isolated cleft lip (122). Boys predominated in cleft lip and palate and cleft lip; whereas, girls predominated in isolated cleft palate, with boy to girl ratios of 1.6:1, 1.2:1, and 0.9:1 for cleft lip and/or palate, isolated cleft lip, and isolated cleft palate, respectively. The Riyadh region had more cases (32.0%) than the Asir (15.6%) and Eastern (14.6%) regions. Parents of 439 individuals had consanguineous marriages. A positive family history of cleft was seen in 224 cases. Of 238 cases with associated anomalies, 91 had congenital heart disease. Of the children with isolated cleft palate, 40.5% had associated anomalies, whereas only 23.0% of the children with isolated cleft lip or cleft lip and palate had associated malformations. Conclusion: The pattern of cleft observed in this study does not differ significantly from those reported in the literature for Arab populations.

SummaryIn a search for genetic differences in susceptibility to cleft lip with or without cleft palate [CL(P)], congenic and recombinant inbred strains of mice were treated with phenytoin or control injections. Of six loci tested, five were found to affect susceptibility to phenytoin-induced and/or sporadic CL(P): (1) the major histocompatibility locus, H-2; (2) the locus controlling β2-microglobulin, B2m; (3) a locus controlling β-glucuronidase, Gus; (4) the locus controlling N-acetyl transferase, Nat; and (5) the locus for brown pigmentation, b. B2m and Gus only affected the sporadic incidence of CL(P), while the b locus only affected phenytoin-induced incidence of CL(P). Three of these loci are also known to affect glucocorticoid-induced isolated cleft palate (CP), but different alleles of the loci are involved. Phenytoin did not affect levels of adenosine 3′,5′-cyclic monophosphate (cAMP) in palates and tongues of day 15 fetuses. A comparison of glucocorticoid receptor parameters with the incidence of phenytoin-induced CL(P) found no correlation.

Objective Using the systematic review method, (1) to identify the investigations of the parental dentocraniofacial phenotype in orofacial clefting, (2) synthesize the data to derive a model of the phenotypic features that will assist in the identification of cleft morphogenes, and (3) make recommendations for the future global strategy for researching the parental craniofacial phenotype in orofacial clefting. Search Strategy The Cochrane, Medline (via PubMed and OVID platforms [1966 to December 2006]), Embase, CINAHL, and ASKSAM Orthodontic Reference Database (1950–1997) databases were searched using a combination of the following keywords: microform, parent, craniofacial, dental, and cleft. All published articles were reviewed. There were no exclusions of non-English reports. Of the 36 studies identified using this strategy, 26 met the inclusion criteria. Data Abstraction/Synthesis The statistically significant data were abstracted using a pro forma, and the methodological quality of the selected studies was evaluated using a checklist. There was considerable heterogeneity among the studies, and therefore it was not possible to synthesize the data. We were, however, able to collate the data. Results/Conclusions (1) The craniofacial phenotype possessed by parents of children with orofacial clefting is distinctive when compared with that of the noncleft population. (2) There is insufficient evidence to produce a model of the phenotypic features to assist in the search for orofacial clefting morphogenes. (3) The pattern of expression of the phenotypic features identified to date supports the contention that there are differences in the inheritance of cleft lip with or without cleft palate and isolated cleft palate. Progress in this field is affected by extreme heterogeneity in etiology of cleft lip with or without cleft palate, as well as heterogeneity in study design. (4) Subphenotyping using features such as microforms should be employed to reduce the heterogeneity and to improve the power of future genetic investigations and will also assist in clinical management and genetic counseling for families.

The birth weight and gestational age of 1368 newborns with isolated cleft lip with or without cleft palate and 582 with isolated cleft palate were compared to those of matched healthy controls. The results indicate that fetuses with oral clefts are at elevated risk of having low and very low birth weight, but not of having a premature birth. Speculations on a relationship between these findings and the presence of oral clefts are presented.

As fissuras labiopalatinas (FLP) são as malformações congênitas mais comuns da região craniofacial e apresentam diferentes fenótipos e características clínicas, que diferem entre si de acordo com as estruturas anatômicas envolvidas: fissura de lábio, fissura de lábio e palato e fissura de palato isolada. A etiologia das FLP é multifatorial e inclui fatores genéticos e ambientais. O objetivo do presente estudo foi investigar o papel das fissuras labiopalatinas na prevalência de cárie dentária por meio de uma revisão na literatura. O defeito anatômico que envolve o rebordo alveolar e/ou o palato pode resultar em agenesias dentárias, dentes supranumerários, anomalias de forma e estrutura, bem como atresia maxilar, mordidas cruzadas posteriores e apinhamentos dentários. Também, a presença da FLP pode resultar aos indivíduos problemas durante alimentação, pronúncia de alguns fonemas, audição e integração social, o que poderia afetar a qualidade de vida do indivíduo e da dinâmica familiar. Quando a saúde bucal de crianças e adolescentes com FLP foi investigada, maior retenção do biofilme microbiano nas superfícies dentárias, de inflamação gengival e maior ocorrência de cárie dentária foram observados. Para um diagnóstico e tratamento adequados, é fundamental uma abordagem multidisciplinar, individualizada, para orientação e planejamento do tratamento dos indivíduos com a malformação, desde o nascimento até a fase adulta. O conhecimento dos efeitos da FLP na saúde bucal e no bem-estar dos indivíduos e das famílias afetadas é fundamental para mudanças nas políticas públicas das práticas de saúde e redução da sobrecarga da presença da malformação congênita.   Palavras-chave: Cárie Dentária. Fenda Labial. Fissura Palatina. Saúde Bucal   Abstract Cleft lip and palate (CLP) are the most common congenital malformations of the craniofacial region and they present different phenotypes and clinical characteristics, which differ according to the anatomical structures involved: cleft lip, cleft lip and palate and isolated cleft palate. The etiology of CLP is multifactorial and includes genetic and environmental factors. The aim of this study was to investigate the role of cleft lip and palate in the prevalence of dental caries through a literature review. The anatomical defect involving the alveolar ridge and / or the palate can result in dental agenesis, supernumerary teeth, anomalies in shape and structure, as well as maxillary atresia, posterior cross bites and dental crowding. Also, the presence of CLP can result in problems for individuals during feeding, pronunciation of some phonemes, hearing and social integration, which could affect the individual's quality of life and family dynamics. When the oral health of children and adolescents with CLP was investigated, greater retention of microbial biofilm on dental surfaces, gingival inflammation and the occurrence of dental caries were observed. For an adequate diagnosis and treatment, a multidisciplinary and individualized approach is essential to guide and plan the treatment of individuals with the malformation, from birth to adulthood. The knowledge of the effects of FLP on oral health and on the well-being of affected individuals and families is fundamental to changes in public health practice policies and to reduce the burden of the presence of the congenital malformation.   Keywords:  Cleft Lip.

Relationships between the width of the palatal cleft measured at paIatopIasty and the craniofacial morphology or the occlusal conditions present at approximately 4 years of age were studied in 25 cleft palate (CP) and 39 complete unilateral cleft lip and palate (UCLP) subjects treated at the Dental Clinic of Kyushu University. Posteroanterior cephalograms and dental casts showed that the width of the palatal cleft was significantly correlated with wider upper facial width and posterior dental arch width in UCLP, but not in CP subjects. Cleft width was not significantly correlated with the buccolingual occlusal relationship in either subject type. The anterior occlusal relationship in UCLP was not as good as in CP subjects. On lateral cephalograms, the width of the palatal cleft was significantly correlated with vertical hypoplasia of the upper face in UCLP, but not in CP subjects. The cleft palate width appears to be related to the lateral displacement and the retardation of the downward and forward growth of the nasomaxillary complex in UCLP subjects.
