In Japan, one of the duties of the long-term care insurance system is the prevention of oral function degradation. Although various exercise programs for oral function have been developed and practiced in Japan, to date, no study has reported their effects. In the present study, we examined the effects of an exercise program on oral functions in healthy elderly people. Healthy elderly people participated in the study and were randomly divided into intervention and control groups (39 subjects/group). The exercise program consisted of four exercises: exercise for expression muscles, tongue, salivary glands, and swallowing. Before and after a six-month intervention period, we evaluated changes in oral functions, namely bite force, swallowing ability, and salivary flow rate. Fifty-four subjects completed the study protocol: 26 and 28 subjects from intervention and control groups, respectively. A significant improvement in all oral functions, including bite force, swallowing ability, as well as unstimulated and stimulated salivary flow rate, was observed in the intervention group after six months, whereas no improvement was observed in the control group. Further, among the intervention group, a significant improvement in oral functions was observed in 17 subjects with 20 or more remaining teeth, whereas no improvement was observed in the other nine with less than 20 teeth. Our results suggest that oral functions significantly improve after conducting a six-month exercise program for oral function. Further, this improvement appears to be influenced by the number of remaining teeth.exercise program for oral function; healthy elderly people; long term care insurance; stretching exercise; number of remaining teeth.Tohoku

“…It has been reported positive correlations between caries activity test score and the counts of Streptococcus mutans and Lactobacillus (7). Actually exist another colorimetric salivary test used as indicator at inflammation which involves determining occult blood derived from the gingival tissue for evaluates periodontal disease in initial stages, called Salivaster ® (Showa Yakuhin Kako Co. LTD, Tokyo, Japan) (8,9). It is important to identify the changes in the oral environment in patients undergoing orthodontic treatment with fixed appliances.…”

Objectives: The aim of this study was to identify changes in the oral environment with clinical, salivary and bacterial risk markers after placement of fixed orthodontic appliances on permanent dentition. Material and Methods: With ethical approval, we used different techniques to analyzed clinical, salivary and bacterial risk markers in 34 patients (mean age, 16.7 ± 5.2 years), 14 males and 20 females; before starting orthodontic treatment and 1 month after. Clinical risk markers (decayed, missing, and filled surfaces [DMFS], O'Leary´s plaque index, and plaque pH); salivary markers (unstimulated and stimulated saliva flow rate, buffer capacity, pH, and occult blood in saliva) and bacterial counts (Streptococcus mutans and Lactobacillus). Data were analyzed by paired t-test and χ 2 test. Results: This study showed that orthodontic appliances increased the stimulated salivary flow rate (p=0.0001), buffer capacity (p=0.0359), salivary pH (p=0.0246) and occult blood in saliva (p=0.0305). Bacterial levels increased slightly after 1 month of treatment, without statistical significance. Between genders, initially we observed differences in: stimulated saliva (p=0.0019), buffer capacity (p=0.0381) and plaque pH (p=0.0430); after treatment the unstimulated saliva (p=0.0026) showed differences. Conclusions: Orthodontic treatment changes the oral environmental factors, promotes an increase in stimulated flow rate, buffer capacity and salivary pH, which augment the anti caries activity of saliva. In contrast, increased occult blood indicated more gingival inflammation, apparently because augmented the retentive plaque surfaces and the difficult to maintain a good oral hygiene, rinsed the bleeding in saliva by periodontal damage.

Objective: To identify clinical, salivary, and bacterial changes during orthodontic treatment with follow-up to 24 months. Methods: In 30 patients, clinical (decayed, missing, and filled surfaces [DMFS], O'Leary's plaque index, and plaque pH), salivary (unstimulated and stimulated saliva, buffer capacity, pH, and occult blood), and bacterial (Streptococcus mutans and Lactobacillus) markers were evaluated. A questionnaire was employed to evaluate their hygienic-dietary habits. Data were analyzed by ANOVA, logistic regression and Spearman's correlation. Results: DMFS increased significantly, whereas the plaque index diminished, plaque pH was more acidic (p = 0.23), and unstimulated salivary flow showed significant differences during the treatment (p = 0.013). Stimulated saliva flow increased in females after the placement of appliances; buffer capacity was diminished in males during the therapy; salivary pH remained at basal values. Bacterial levels and occult blood increased to high-risk levels and were not statistically significant different between genders (p ＞ 0.05). Two major relationships were confirmed: initial plaque with use of dental aids (r = 0.429; p = 0.018) and final DMFS with unstimulated salivary flow (r = −0.372; p = 0.043). Conclusions:The increase in retentive surfaces increased the bacterial levels, plaque pH became acidified, and gingival damage was greater. Buffer capacity was altered but maintained a healthy salivary pH during the treatment.
