A comparison of acidic dietary factors in children with and without dental erosion.

The results of the UK Child Dental Health Survey of 1993 indicated that dental erosion was a problem in children, with acidic dietary components thought to be the main etiological factor. The aim of this study was to compare, in the form of a case control study, the diets of children with dental erosion with those who were caries-active or caries-free. Structured dietary histories were taken from 309 age and gender matched children to determine the type and frequency of intake of acidic foods and drinks, together with any drinking habits that prolonged exposure of the teeth to dietary acids. Results showed that the children with erosion drank acidic beverages significantly more frequently than children who either had caries or were caries-free. Children with erosion also drank milk or water significantly less often than the control groups, and were more likely to have a swishing or holding habit associated with drinking. Fruit and vinegar consumption was higher in the erosion group, as was the taking of vitamin C supplements. The results of this study suggest that the increased consumption of acidic foods and drinks, particularly when associated with a swishing or holding habit, may contribute to the development of erosion in some children. Dietary advice should emphasize the dangers of a highly acidic as well as that of a cariogenic diet.

Dental caries in relation to nutritional stress in early English child populations.

This research studied an association between dental caries prevalence in the primary dentition and cribra orbitale, an indicator of nutritional stress in archeological populations. Skeletal remains of 221 British children (Pre-Roman to Late Medieval) were examined, of whom 100 had orbital material available. Dental caries, as dmfs, was related to the presence of cribra orbitale (none, slight, moderate, or severe). Thus, data for 50 children showed a statistically significant association (P less than 0.005) between caries prevalence and cribra orbitale using the Fisher Exact Test, suggesting that nutritional stress is an associated factor in caries etiology in children.

The dental status of cerebral palsied children.

The prevalence of dental disease, the types and quality of dental care, and the provision of services were assessed for 150 cerebral palsied children (mean age 10.25 years) attending special schools in Leeds and compared with a matched control group of 191 children (mean age 10.39 years). Similar dental caries experience existed in the two groups, but study children had more extracted and unrestored teeth, and fewer and poorer quality restorations than control children. Oral hygiene and gingival health were worse in the study group, which also exhibited delayed eruption and higher levels of tooth wear. Significantly greater overjet (5.1 mm compared with 2.5 mm) and less crowding occurred in the study group than in the control group. All parents had favorable attitudes toward dentistry and were satisfied with their children's dental care. More study children received treatment from the community dental service, while the general dental services were used more commonly by the control group.

Oral complications in pediatric oncology patients.

This study investigated the oral problems occurring in children receiving treatment for malignant disease at a regional oncology center. Forty-three children 2 to 14 years old were followed longitudinally from initial diagnosis for periods ranging from eight to 30 weeks for the development of oral and dental problems. Fifteen children had untreated decay; two required the removal of primary teeth before they began chemotherapy. Three children developed acute dental infections during treatment. Forty (93%) developed oral problems associated with their disease or treatment during the study period. Oral mucosal ulceration was the most frequently encountered problem; it was observed in 28 (65%) patients. In light of the high prevalence of dental and oral problems in these patients, this study emphasizes the need for positive dental involvement, both in pretreatment assessment and in the ongoing care of the pediatric oncology patient.

The influence of restorative material on the survival rate of restorations in primary molars.

The survival rates of restorations in primary molars were calculated after a retrospective examination of patients' dental records from a study population of 1,065 children. A random sample of 128 records showing information for 604 dental restorations was examined, coded, and analyzed by the life table method of survival analysis. The order of the survival rate of restorations from higher to lower success was preformed crowns, amalgam, composite resin, and glass ionomer restorations. A highly statistically significant difference (P = 0.0001) was found among the survival success rates of different material restorations. For preformed crowns and amalgam restorations, the median survival time was more than 5 years. The 5-year survival estimate for preformed crowns was 68% and for amalgam restorations was 60%. For composite resin the median survival time was 32 months and the 4-year survival estimate was 40%. For glass ionomer restorations, the median survival time was 12 months and the 4-year survival estimate was 5%.

The dental status of asthmatic British school children.

PURPOSE: This study was performed to determine the prevalence of dental disease in British school children with asthma. METHODS: A convenience sample of 100 asthmatic children (aged 4-16 years) was examined for dental caries, periodontal condition, and tooth surface loss. School children, equated for age, sex, race, and socioeconomic status were chosen for comparison. Children were divided into two age ranges; 4-10 and 11-16 years. A significant difference was found in DMFT (0.96 vs. 0.31) and DMFS (1.37 vs. 0.37) between the 4-10-year-old asthmatic children compared with healthy control children. RESULTS: In the 11-16-year age range, the asthmatic children had a DMFT and DMFS of 2.48 and 3.39 compared with the control children who had a DMFT and DMFS of 1.11 and 1.97 respectively. Asthmatic children had significantly more plaque, gingivitis, and calculus compared with the control group. There was a significant difference in the severity and number of teeth affected by tooth surface loss affecting labial surfaces of the anterior teeth and occlusal surfaces of the posterior teeth of asthmatic children. CONCLUSIONS: It was concluded that asthmatic children have more decay affecting their permanent teeth, poorer periodontal status, and more tooth surface loss than healthy controls.
