Preventive treatment for high caries-risk individuals: Four sites were completely successful in providing preventive treatment to those children assigned as being at high caries risk, and the fifth provided this treatment for more than three-quarters of high-risk children. In two of the sites, however, the number of children assessed as being at high risk was extremely small. Preventive treatment for low caries-risk individuals: Provision of caries preventive procedures to children assessed as being at low risk and those who were not assessed was not markedly different than for high-risk children, perhaps reflecting the fact that virtually all children exhibited some evidence of caries experience. A smaller proportion of low-risk and unassessed adults received preventive treatment. New caries in high caries-risk individuals: In all but one site, a majority of high-risk children and adults experienced new caries in the year immediately preceding the record audit. It should be noted that this is a surrogate measure, with the incidence of caries presumed to be denoted by receipt of a restoration (Bader et al., 1999b). New caries in low caries-risk individuals: Proportions of low risk and unassessed individuals who experienced new caries in the preceding year were generally lower than for high-risk individuals, but generally reflected new caries experienced by between one-sixth and one-half of all patients. Preventive treatment for perio-present adults: Only two sites provided periodontal maintenance therapy for adults assessed as having periodontal disease, and neither site provided such treatment for a majority of these individuals. The receipt of treatment at two other sites was impossible to determine because no adults had been identified in the clinical record as having periodontal disease. Tooth loss: No child at any site had a permanent tooth extraction in the previous year. At three sites, no adult experienced an extraction, while at the other two sites, 20% of adults lost one or more teeth in the previous year.
4.4.2 Use of Services Measures (Table 4-31) Receipt of prophylaxis: At four sites, one-half or fewer children and adults received a prophylaxis in the previous year. Preventive-to-restorative treatment ratio: For children, the overall ratio was 3.5 preventive procedures provided for every restorative procedure. The value ranged from 2.1 to 4.9 4-24
