A comparison of four home-care fluoride programs on the caries incidence in the elderly.

OBJECTIVE: To estimate the caries preventive effect of 4 fluoride programs over 2 years in the elderly. SETTING: The Public Dental Clinics of Bålsta and Knivsta and the Faculty of Odontology in Göteborg, Sweden. SUBJECTS: One hundred and sixty-four individuals, aged 60 years and older (mean age 71.5 years) who were considered to be at risk from caries. DESIGN: The participants were randomly assigned either to: 1) rinse twice a day with a 0.05% NaF solution (n = 49; rinsing group), 2) suck twice a day on a 1.66 mg NaF tablet (n = 51; tablet group), 3) brush their teeth three times a day using a toothpaste slurry rinsing technique (n = 32; slurry group), or 4) brush their teeth in their usual manner (n = 32; control group). The participants in all 4 groups used a fluoride toothpaste (containing 0.32% NaF) at least twice daily. RESULTS: No new carious lesions were found in 67% of the participants in the rinsing, 43% in the tablet, 25% in the slurry and 16% in the control group over the 2 years. The mean (+/- SD) 2-year caries increment was 0.8 +/- 1.4, 1.4 +/- 1.7, 1.9 +/- 1.9 and 2.3 +/- 2.1 DFS in the rinsing, tablet, slurry and control groups, respectively; it was significantly lower in the rinsing than in the control group (p < 0.01). A lower incidence of DFS was also found in the tablet group than in the slurry group, but only for the lingual surfaces (p < 0.05). CONCLUSION: The type of fluoride program may be of importance in the reduction of new caries lesions in an older population.

Five-year incidence of caries, salivary and microbial conditions in 60-, 70- and 80-year-old Swedish individuals.

The 5-year incidence of dental caries in a random sample of 60-, 70- and 80-year-old inhabitants of Goteborg was related to salivary and microbial conditions. Of the 208 persons examined at baseline, 148 (71%) participated in the follow-up examination; 69, 51 and 28, respectively, in the different age groups. The study revealed that 27% of the participants had not developed any carious lesions during the 5-year period and that the incidence of coronal and root caries increased with age. In the 60-year-olds, 2.5% of the susceptible coronal and root surfaces, respectively, had decayed, while the corresponding figures for the 80-year-olds were 8.8% for coronal surfaces and 9.8% for root surfaces. In all, 18% had an unstimulated saliva secretion rate of below 0.1 ml/min and 14% had a stimulated secretion rate of <0.7 ml/min, with a mean rate which decreased with increasing age from 2.0 to 1.6 and 1.3 ml/min (p = 0.02). The overall salivary counts of lactobacilli and mutans streptococci, particularly the subspecies of Streptococcus sobrinus, had increased during the period. In the respective age groups of 60, 70 and 80 years, 15, 39 and 39% had a mutans streptococci count of > or = 10(6) CFU/ml in saliva and the corresponding figures for > or = 10(5) lactobacilli counts were 22, 31 and 43%. In the stepwise regression analysis, it was found that age, salivary levels of mutans streptococci and lactobacilli and number of teeth were the best predictors of the incidence of root caries. In conclusion, these observations indicate that there is an increased risk of dental caries with age owing to unfavourable microbial and salivary conditions.

Effect of three months' frequent use of sugar-free chewing gum with and without urea on calculus formation.

Studies on the relationship between gum-chewing and calculus formation have produced contradictory results, and it is not clear whether frequent use of chewing gum promotes or inhibits calculus formation. Also, little is known about whether the addition of a small amount of urea to the chewing gum influences calculus formation. The aim of this investigation was to study the effect of sugar-free chewing gum--with and without urea--on calculus formation and some associated clinical variables. Three three-month periods were studied in a double-blind, crossover design, during which the subjects: (1) chewed 5 pieces/day of a sugar-free, urea-containing chewing gum (20 mg urea/piece); (2) chewed 5 pieces/day of a sugar-free, non-urea-containing gum; or (3) performed no gum-chewing. Twenty-nine persons, all calculus-formers, participated. They were scored for calculus at mesio-lingual, lingual, and disto-lingual sites on the 6 anterior mandibular teeth according to the Volpe-Manhold index. Plaque and gingival bleeding index, stimulated salivary secretion rate and buffer capacity, resting plaque pH, mutans streptococci in saliva and plaque, and lactobacilli in saliva were also determined. No differences in calculus formation were found among the 3 periods. The resting plaque pH was higher after the period with urea-containing gum than after the period with non-urea-containing gum and the no-gum period (p < 0.05). A slight increase in stimulated salivary secretion rate was found after the 2 gum periods (p < 0.05). The plaque and gingival bleeding indices decreased, while resting plaque pH and salivary buffer capacity increased throughout the entire study (p < 0.05). No significant differences in prevalence of the acidogenic micro-organisms were found among the test periods. The main conclusion from this study is that three months' frequent use of sugar-free chewing gum--with or without urea--neither promotes nor inhibits calculus formation.

Incidence of tooth loss and dental caries in 60-, 70- and 80-year-old Swedish individuals.

The retention of natural teeth among the elderly is increasing and, in recent studies, dental caries has been identified as the main reason for teeth being extracted. The 5-year incidence of tooth loss and dental caries and the most crucial dental factors for tooth extraction were studied in a random sample of 60-, 70- and 80-year-old inhabitants of Gothenburg. Of the 208 persons examined at baseline, 148 (71%) participated in the follow-up examination: 69, 51 and 28 respectively in the different age groups. In all, 110 teeth had been extracted during the period in 40% of the participants. Only 9 persons had lost three or more teeth. The mean numbers of remaining teeth were 22. 18 and 15 respectively in the 60-, 70- and 80-year age groups and the mean numbers of teeth lost during the 5-year period increased with age from 0.4 in the 60-year-olds to 0.8 and 1.4 in the 70- and 80-year-olds (P < 0.05). The major reason for tooth extraction was dental caries and it was found in 60% of all cases and at a higher rate of 77% in the oldest age group. Fifty-one per cent had developed new coronal carious lesions and 61% had new root carious lesions, while 27% had not developed caries during the period. The mean 5-year increment in decayed and filled coronal surfaces increased with age from 2.3 in the 60-year-olds to 3.7 and 5.3 in the 70- and 80-year-olds (N.S.I. The increment in decayed and filled root surfaces was higher in women than men, 3.4 compared with 1.8 (N.S.), which also increased with age from 1.4 in the 60-year-olds to 2.4 and 5.5 in the 70- and 80-year-olds (P < 0.0001). It was concluded from this study that few teeth had been lost during the 5-year period but that dental caries still appeared to be a serious problem among some very elderly people.

Five-year incidence of coronal and root caries in 60-, 70- and 80-year-old Swedish individuals.

The 5-year incidence of caries was studied in a random sample of 60-, 70- and 80-year-old inhabitants of Göteborg, with 69, 51 and 28 individuals in the different age groups. One aim of the study was to introduce a root caries index (DMFRS%) in which the missing root surfaces are taken into account. This study, as well as other recent studies, has shown that dental caries is the main reason for tooth extraction. The study also revealed that coronal and root caries occurred more frequently in elderly than younger people and the incidence of root caries was positively correlated with coronal caries (r = 0.3, p < 0.001) and negatively correlated with the number of remaining teeth (r = 0.4, p < 0.0001). The 5-year DMFRS% increment values increased with advancing age from 2.7 involved root surfaces per 100 susceptible ones in the 60-year-olds to 4.8 in the 70-year-olds and 10.7 in the 80-year-olds. It should be mentioned, however, that only people able to come to the clinic were enrolled in the study and an analysis of the attrition bias indicated that oral health may be worse in those who are too ill to participate. The frequent utilization of dental care among the participants was reflected in the finding of several new fillings and prosthetic crowns. Most of the very elderly people with carious lesions at baseline, however, had developed new lesions at the margins of the newly made restorations.

Prevalence of root surface caries in 55, 65, and 75-year-old Swedish individuals.

The prevalence and intraoral distribution of decayed and filled root surfaces were evaluated in 55, 65, and 75-yr-old inhabitants of Gothenburg. From randomly selected groups, 88, 72, and 48 dentate persons in the respective age groups participated and as many as 85, 93, and 90% respectively had one or more decayed or filled root surfaces. In the two oldest age groups 32-35% were free from root carious lesions, while 20% had five or more decayed root surfaces. The corresponding figures for the youngest group were 63% and 8%. The prevalence of root surface caries was evaluated using the Root Caries Index (RCI), excluding prosthetic crowns. The mean RCI value increased with age (P less than 0.05, ANOVA on age groups) from 14% to 16% and 22% in the 55, 65, and 75-yr-olds, respectively. The root surfaces of the molars were most frequently affected by caries and fillings, the incisors least frequently. In the maxilla the proximal surfaces were most affected, in the mandible this applied to the buccal surfaces, while the lingual surfaces had the lowest proportion of carious lesions and fillings in both jaws.

Salivary conditions and cariogenic microorganisms in 55, 65, and 75-year-old Swedish individuals.

Secretion rate, buffer capacity, and cariogenic microorganisms of resting and stimulated whole saliva were examined in 208 55-, 65-, and 75-yr-old Swedes. The secretion rate for both resting and stimulated saliva decreased with age. When the use of drugs was taken into account the difference in terms of age group was significant for resting saliva alone (P less than 0.01). In 22% the resting saliva was less than 0.1 ml/min, and in 5% the stimulated saliva was less than 0.7 ml/min. Persons with subjective dryness in the mouth had a lower salivary flow. Men had higher secretion rates than women irrespective of medication (P less than 0.05). The buffer capacity was strongly correlated to the secretion rate of both resting and stimulated saliva (r = 0.39 and r = 0.44, respectively). The number of mutans streptococci and lactobacilli increased with age, although significant in terms of age group for lactobacilli alone (P less than 0.05). The number of these microorganisms was lower in resting saliva than in stimulated saliva (P less than 0.0001). Individuals harboring both Streptococcus mutans and Streptococcus sobrinus had higher values of mutans streptococci in resting and stimulated saliva than those harboring only S. mutans (P less than 0.001). Actinomyces viscosus and Actinomyces naeslundii comprised greater than or equal to 1% of the total CFU in 89% of the plaque samples. The corresponding figures for lactobacilli and mutans streptococci were 6% and 38%, respectively.

Root surface caries and associated factors.

The prevalence of root surfaces caries in 208 randomly selected 55, 65, and 75-yr-old Swedes was related to the frequency of coronal caries, the number of remaining teeth and to bacteriologic, salivary, and dietary variables. At least one decayed or filled root surface was found in 89% of the individuals and all of those had also experienced coronal caries. The frequency of root surface caries was positively correlated to the frequency of coronal decay and negatively correlated to the number of remaining teeth and exposed root surfaces. The study shows that the same factors which are associated with enamel caries seem to be of importance in determining the development of root surface caries. The variation in the frequency of root surface caries was best explained by the salivary levels of mutans streptococci and lactobacilli, the percentage of surfaces harboring plaque and the frequency of carbohydrate intake. Other contributory factors were the saliva secretion rate and the buffer capacity.

Effect of chlorhexidine gel treatment supplemented with chlorhexidine varnish and resin on mutans streptococci and Actinomyces on root surfaces.

The supplementary effect of chlorhexidine varnish and resin on the reappearance of mutans streptococci and Actinomyces spp. on root surfaces after chlorhexidine gel treatment was studied. In 8 subjects with many restored tooth and exposed root surfaces, highly colonized with mutans streptococci, chlorhexidine varnish and resin were applied to the teeth on one side of the mouth and resin alone to the other side. This treatment significantly prolonged the time period of reduced salivary levels of mutans streptococci when added to a preceding period of chlorhexidine gel treatment. In 3 of the 8 subjects, mutans streptococci were undetected for more than 4 weeks after treatment. There was a significant difference between the chlorhexidine varnish/resin side and the resin side for 5 weeks with regard to the mean numbers of mutans streptococci in root surface plaque, whereas for the Actinomyces spp. no significant differences were found. In 2 subjects harboring both Streptococcus mutans and S. sobrinus, the population of S. sobrinus reappeared more readily in saliva and plaque than S. mutans. The chlorhexidine treatment was less effective in suppressing the population of Actinomyces viscosus/naeslundii than the mutans streptococci.

Proportions of Streptococcus mutans, lactobacilli and Actinomyces spp in root surface plaque.

The incidence of Streptococcus mutans, lactobacilli and Actinomyces was examined in root surface dental plaque from 24 subjects with root surface caries and in 24 subjects with exposed root surfaces as a consequence of periodontitis but without root surface caries. Plaque was collected from the most posterior teeth in each quadrant: in the caries group from carious lesions and in the periodontitis group from buccal root surfaces. There were significantly higher proportions of S. mutans and lactobacilli in dental plaque samples taken from subjects suffering from root surface caries than in samples from subjects without root surface caries. The level of the group A. viscosus/naeslundii in the periodontitis group was higher than that found in the root surface caries group, but the difference was not statistically significant.

Evaluation of Carisolv for the chemo-mechanical removal of primary root caries in vivo.

The objective of this study was to evaluate a new chemo-mechanical method (Carisolv) for the removal of primary root caries in vivo in terms of efficiency, treatment time and patient perception. Thirty-eight patients participated in an open, randomised and controlled study. Of the 60 root carious lesions included, 34 were randomised for chemo-mechanical treatment and 26 for drilling. A within-subject comparison was used whenever the patient had two cavities, which was the case for 22 subjects. All the Carisolv-treated cavities became caries free, as did all but one of those treated with drilling, as judged by an independent examiner. Only 4 of 34 patients asked for anaesthesia in the Carisolv group compared with 6 of 26 patients in the drilling group. Of those who did not use anaesthesia, 12 individuals in the drilling group experienced some pain compared with none in the chemo-mechanical group (p<0.001). The mean treatment time for the Carisolv method was 5.9+/-2.2 min, compared with 4.5+/-2.0 min for drilling; time for anaesthesia excluded (p<0.05). No negative reactions or adverse effects were recorded during the study. All 55 teeth examined in the 1-year follow-up were found to be sensitive using an electric pulp tester, and there was no difference regarding the condition of fillings between the lesions treated with Carisolv and drilling. It can be concluded that root caries can be effectively removed using the Carisolv method. The longer treatment time was compensated by less need for anaesthesia.
