In a central institution for persons with mental retardation, the dental status in 30 adult patients with Down syndrome was compared with that in a carefully selected group of gender- and age-matched mentally retarded patients. This investigation showed an increased frequency of periodontitis in the population with Down syndrome. The caries rate, however, did not differ demonstrably between the groups. Edentulism was more frequent in patients with Down syndrome than in controls, and this fact may substantiate the observation of increased frequency of periodontitis. Caries seems to be less prevalent in institutionalized patients with mental retardation than in the population at large.

Cockayne's syndrome is a rare, autosomal recessive disorder characterized clinically by cachectic dwarfism, cutaneous photosensitivity, loss of adipose tissue, mental retardation, skeletal and neurological abnormalities, and pigmentary degeneration of the retina. Dental caries is a common finding. The case of a 4-year-old male with Cockayne's syndrome is presented. A dental rehabilitation involving outpatient surgery is described including the difficulties encountered because of a small oral cavity and restricted mandibular range of motion.

Mentally retarded individuals are, since 1984 a priority group for the Norwegian public dental health service. This group of patients may have many problems which affect oral health. Difficulties with feeding are common, as are various oral motor problems like rumination, bruxism, mouth breathing and drooling. The impaired oral function may cause retention of food, reduced self-cleaning from lips and tongue and long-term use of puree food. Obstipation is a common problem which is often treated with prunes, raisins or sweetened laxatives. In behaviour modification programs sweets are often used as rewards. Tooth cleaning may cause problems for many parents and caretakers due to lack of cooperation or anatomical malformation of oral structures or teeth. Dental treatment may also be difficult to perform. Recent research in Nordic countries supports earlier reports that mentally retarded individuals have a high incidence of plaque, periodontal disease and malocclusion. Caries does not seem to be a problem. Nevertheless, older individuals with mental retardation have more untreated caries and missing teeth than average. Early intervention with oral motor training and frequent regular preventive treatment (4 x per year) will reduce caries, periodontal disease, early tooth loss and the need for treatment under general anesthesia in the future.

In this study, we investigated the oral conditions of 77 handicapped children (57 boys and 20 girls) and backgrounds of living in an institution. The results were as follows. Among 73 children having permanent dentition, the percentage of subjects with one or more DMF teeth was 94.52%, while DMFT was 7.45. The percentage of teeth treated for dental caries was 57.35%. GI (Gingival Index) was 1.7, and OHI-S was 3.50. The other features observed were attrition of posterior teeth in 25 subjects and crowding in 39. According to the degree of mental retardation, severely retarded children had a lower percentage of teeth treated for dental caries than moderately and mildly retarded children. Additionally, the severely retarded handicapped children who were long-time institutionalized and taking antispastic drugs, had the higher incidence of gingivitis and poor oral hygiene. This study indicated the necessity of a scheduled and active practice in order to improve oral hygiene status and gingival condition, and raise the percentage of teeth treated for dental caries of severely retarded children in an institution.

Prader-Labhart-Willi Syndrome is a complex, multisystem sporadic disorder which presents during childhood and proceeds into adulthood. The major features include infantile hypotonia, developmental delay, hypogonadism with abnormal sexual maturation, mental retardation and behavior abnormalities, short stature with small hands and feet, massive obesity with diabetes mellitus, dysmorphic facial features, and marked dental caries and enamel hypoplasia. Recently, a deletion of chromosome 15 has been found in a large percentage of these patients, but the exact cause and genetic transmission has not yet been determined. Two cases of Prader-Labhart-Willi Syndrome are presented with emphasis on the differential diagnosis of enamel hypoplasia associated with sexual maturation.

The prevalence of dental caries, the levels of oral hygiene and the periodontal treatment requirements were assessed in 3562 handicapped children and 1344 randomly selected normal children attending schools in Birmingham, UK. The effect of different types of handicapping condition on these parameters was also evaluated. This investigation showed that there were few differences in caries prevalence when comparing handicapped children with children attending normal schools. However, the provision of dental care showed significant differences, with the handicapped children receiving less restorative treatment. There were also significantly poorer levels of oral hygiene and a greater prevalence of periodontal disease in the handicapped children attending special schools. The type of handicapping condition had a significant effect on the periodontal problems observed; those children with mental retardation having the poorest levels of oral hygiene and the greatest periodontal treatment requirements.

A sporadic case of Crouzon Syndrome without mental retardation is described. The patient, an 11 year old boy with grossly carious teeth and in severe pain was referred for dental treatment. A review of literature on Crouzon Syndrome is presented.

Childhood poverty is common in Canada: 1,114,000 children under 16 years of age live below the poverty line. The incidence is highest among children of single mothers, unemployed parents, Canadian native peoples and recent immigrants, particularly refugees. Compared with the national average, the infant mortality rate is twice as high, deaths from infectious diseases are 2.5 times more common and accidental deaths are twice as common among children of low-income families. Other problems associated with poverty are iron deficiency anemia, dental caries, chronic ear infections, mental retardation, learning disabilities, poor school performance and increased suicide rates. Health care professionals can help address the poor physical and mental health associated with poverty in children by promoting a broad range of public policies.

We describe a large, three generation kindred in which 16 individuals were affected with alopecia, hyposmia or anosmia, conductive deafness associated with protruding ears, microtia, and/or atresia of the external auditory canal, hypogonadotropic hypogonadism due to LH/FSH deficiency, and a greater than normal tendency to dental caries. Variable manifestations include mild facial asymmetry, mental retardation, congenital heart defect, and cleft palate. This seems to be a previously undescribed pleiotropic autosomal dominant trait with variable expressivity. The manifestations can be explained on the basis of involvement of the ectoderm and neuroectoderm of the first and second branchial arches, of Rathke's pouch, and of the diencephalon.

Oral hygiene has been implicated as a casual factor in the development of dental caries and periodontal disease in mentally retarded individuals. Little attention, however, has been given to the determinants of oral hygiene status. The present paper assesses the oral hygiene status of institutionalized (I) and noninstitutionalized (NI) mentally retarded (MR) individuals aged 4 through 25, in relation to age, degree of mental retardation, and socioeconomic status. Institutional status was found to be a major determinant in oral hygiene conditions of the study group, as IMR individuals had significantly higher OHI scores than NIMR individuals. Associations of age and OHI were significant only for NIMR. Although differences between I and NI groups, with respect to degree of mental retardation, were seen for mildly, moderately, and severely retarded, no significant difference in OHI scores between I and NI profoundly retarded was seen. Socioeconomic status was not found to be a significant factor in the oral hygiene status of MR individuals. This study emphasizes the need to assess age, degree of mental retardation, and institutional status when implicating oral hygiene in caries and periodontal disease prevalence in MR individuals.
