Smoking and Periodontal Disease in the Finnish Population Aged 30 Years and Over

The aim of this study, which was part of the Mini-Finland Oral Health Survey, was to evaluate the effect of smoking on periodontal condition in the Finnish adult population. A representative sample was drawn from the population aged 30 years and over. The total number of subjects was 8000, 90% of whom participated in the clinical examination. Periodontal diagnoses were made according to the modified Periodontal Treatment Need System (PTNS). Information about age, toothbrushing, and smoking habits was collected by personal interviews. When the sample was divided into two groups (with and without periodontal pockets), the overall risk ratio (RR) was 1.39 and was slightly higher for men than for women. A log-linear model was used to study simultaneous associations and interactions between smoking, periodontal disease, and some background factors. In this model, smoking had not significantly affected the periodontal condition.

“…In their study, Markkanen and co-workers showed that the age of the patient is a significant factor for periodontal treatment need (8). According to a Swedish study (9), multiple periapical lesions were more usual in the age group 75 years and older than in the group 65±74 years.…”

In the oldest elderly, an increase in the number of remaining teeth may increase oral infection foci. The aim of this follow-up study was to examine the radiologically detected oral health condition of a group of home-living elderly in Helsinki at 5-year intervals. The population of this study comprised 103 home-living elderly people, all participants of the population-based Helsinki Aging Study. Panoramic radiography supplemented by intraoral radiographs was performed on all these participants at the Institute of Dentistry, University of Helsinki, in 1990-1991. Follow-up radiographic examination was completed in 1995-1996. Mean number of teeth decreased during the follow-up period from 13.2 +/- 9.0 to 12.5 +/- 9.2 (P= 0.0001). Mean number of teeth with periapical lesions decreased in men from 1.3 +/- 1.4 to 0.6 +/- 0.9 (P = 0.007), but no differences in number of teeth with periapical findings were observed in women. There were relatively few changes in the subjects' radiographic periodontal findings. However, fewer teeth with vertical bone pockets >1-3 mm deep were found in the follow-up study than 5 years earlier (0.6 +/- 1.2 vs 1.1 +/- 1.8; P= 0.0008). In both the baseline and the follow-up studies the radiographic findings occurred in the subjects who had retained more natural teeth. In the follow-up study, 68% of the subjects had radiographically detected signs of chronic oral infection foci. It may be concluded that radiographically detected oral health parameters remain relatively unchanged, but treatment need is higher among those who have successfully retained their natural dentition into old age.

“…The indicators used to describe periodontal conditions were presence or absence of gingival inflammation or periodontal pockets and subgingival plaque retentions (calculi and/or overhang ings). Based upon the PTNS index [Johansen et al, 1973;Markkanen et al, 1983], the state of the periodontium was first placed in 1 o f 4 cat egories: 1 = healthy; 2 = gingival inflammation; 3 = pockets 4-6 mm deep, and 4 = pockets > 6 mm deep. In further analyses, the severity of periodontal disease was described according to presence and depth of pockets, using these three categories: 1 = no deepened pockets; 2 = pockets 4-6 mm deep, and 3 = pockets > 6 mm deep.…”

To analyze the occurrence of root caries in relation to the periodontal state, we examined clinically a representative sample (n = 4,777) of Finish adults, aged 30 years and older. Our definition of root caries included primary decay on root surfaces, and a subject’s periodontal state was described according to the presence or absence of gingival inflammation or periodontal pockets and subgingival calculus and/or overhangings. Subjects with a healthy periodontium seldom (4%) had any caries on root surfaces, whereas 15% had caries in conjunction with gingival inflammation, and 17% in conjunction with deepened pockets. The deeper the pockets, the greater the frequency of root caries for men, but not for women. Subgingival plaque retention showed a strong association with root caries. As the study population represented Finnish adults, the results can be generalized with reasonable confidence.
