    Abstract:
    OBJECTIVE: The 10-year incidence of dental caries was related to some associated factors in a random sample of 65, 75 and 85-year-old inhabitants of Gothenburg. SUBJECTS: Of the 208 persons examined at baseline, 102 (49%) participated in the follow-up examination; 56, 37 and nine, respectively, in the different age groups. For the purpose of time-trend comparisons, a new random sample of 98 individuals aged 55 years was examined. RESULTS: Ninety-five per cent of the participants had developed one or more carious lesions during the 10-year period and the incidence of coronal and root caries increased with age. In the 65-year-olds, 9% of the root surfaces had decayed during the period, compared with 25% in the 85-year-olds. Secondary caries predominated over primary caries and prosthetic crowns accounted for 70% of the restored tooth surfaces. Twenty per cent of the individuals were daily smokers and 61% were taking drugs with hyposalivatory side-effects. The mean saliva secretion rates were lower in the older groups compared with the 'younger' ones. The overall salivary counts of mutans streptococci and lactobacilli had increased during the period and the values were highest in the oldest age groups. Salivary levels of lactobacilli and mutans streptococci, number of teeth, daily numbers of cigarettes and drugs and oral hygiene were the best predictors of the incidence of caries. CONCLUSION: The findings indicate that there is an increased risk of dental caries with age owing to unfavourable caries-related factors.
