title: Epidemiology of dental caries in the premolar and second molar teeth of Scottish children in relation to pits and fissures.
abstract: To evaluate the potential benefits from elimination of dental caries in the fissures of teeth, surface patterns of decay were calculated for all surfaces of the premolar and second molar teeth of 98 children followed longitudinally for 5 years, between ages 11 and 15 years. Tooth eruption and susceptibility were also examined in relation to the administration of sealant programs. The children who were part of the control group of a fluoride dentifrice study on the Scottish Isle of Lewis, had low exposure to fluorides, high caries attack and very low restorative treatment levels; so true surface caries distribution was not masked. Variation in tooth eruption and susceptibility suggested that semiannual applications of preventive agents at each year age 10 through 15 might be required. Using hypothetical percentage reductions, the substantial potential benefits for caries control of the early use of completely retained occlusal, as well as buccal and lingual (molars), fissure sealants are conclusively demonstrated. However, improvements in the present technology of fissure sealants and their application are apparently required if these benefits are to be extended to large groups of children.
