The dental condition of 626 12-year-old handicapped children with mild mental or moderate to severe mental retardation or learning impairment, being 25% of the population of each of these groups, was examined in Flanders. An evaluation of oral cleanliness showed poor oral hygiene in 31.8% of the children. No significant differences were found in oral cleanliness among types of handicapping conditions. The mean DMFT score was 2.9 (s: 2.6) and DMFS score was 5.4 (s: 5.6). Almost 21% of the children were free of caries or fillings. No significant differences were found among groups of handicapped children. Handicapped children presented a low level of restorative care (restorative index score: 48.7%). Mildly mentally retarded children demonstrated the lowest restorative index (43.9%). The caries experience of first permanent molars represented the largest part of the DMFT score (64.1%). Sealants were present in 7.9% of children examined. A considerable percentage of mildly mentally retarded children and learning impaired children did not brush daily (22.1% and 20.9%) and did not receive help with toothbrushing from their parents or carers (91.0% and 94.7%, respectively).
The technique used at this centre allows for extensive dental treatment of young children with a high level of acceptability and minimal morbidity, using day-stay general anaesthesia. Based on this review, it became clear that less upsetting methods for the induction of anaesthesia need to be explored. Criteria for the administration of antibiotics need to be defined more clearly and the use of stainless steel crowns should be envisaged for restorations on primary molars. The global outcome of this treatment provision in children at high caries risk should be evaluated over a longer period, including an evaluation of oral health status, restorative treatment (conservation vs. extraction) and behavioural aspects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
