ABSTRACT: The aim of this study was to assess the relative weights of each factor related to tooth retention identified in our previous study with an objective of developing a risk assessment tool that could be incorporated into a self-administered oral salutogenic checklist.
Oral health status and lifestyle were investigated in 777 subjects aged > or = 20 years. Eleven items that had a statistically significant odds ratio of being related to the number of retained teeth in our previous study were identified. Discriminant analysis was used to calculate the scores for each item.
Based on the discriminant analysis, the variables affecting tooth retention, from the most to the least important, were 'gum swelling' (1.241), followed by 'toothache' (0.766) and 'do you have any hobbies' (0.691). Based on the above analysis, a total of 20 points were allocated in proportion to the ranges. The final oral salutogenic score (OSS) was swollen gums (4), toothache (3), frequency of between-meal snacks (3), having some hobbies (3), having a family clinician (2), consulting a clinician when having dental symptoms (1), bleeding gums (1), frequency of tooth brushing (1), having one's own toothbrush (1) and smoking (1).
A self-administered checklist for the OSS was designed. The first part contains a list of questions for the participants to fill out. The second part offers comments depending on the range of score values. The suggestions include advice to decrease or to stop the behaviours for which the subject obtained zero points.

ABSTRACT: The aim of this study was to determine which behavioral factors to include in guidelines for the Japanese public to achieve an acceptable level of oral healthiness. The objective was to determine the relationship between oral health related behaviors and symptoms related to oral disease and tooth loss in a Japanese adult community.
Oral health status and lifestyle were investigated in 777 people aged 20 years and older (390 men and 387 women). Subjects were asked to complete a postal questionnaire concerning past diet and lifestyle. The completed questionnaires were collected when they had health examinations. The 15 questions included their preference for sweets, how many between-meal snacks they usually had per day, smoking and drinking habits, presence of oral symptoms, and attitudes towards dental visits. Participants were asked about their behaviors at different stages of their life. The oral health examinations included examination of the oral cavity and teeth performed by dentists using WHO criteria. Odds ratios were calculated for all subjects, all 10 year age groups, and for subjects 30 years or older, 40 years or older, 50 years or older, and 60 years or older.
Frequency of tooth brushing (OR = 3.98), having your own toothbrush (OR = 2.11), smoking (OR = 2.71) and bleeding gums (OR = 2.03) were significantly associated with number of retained teeth in males. Frequency of between-meal snacks was strongly associated with number of retained teeth in females (OR = 4.67). Having some hobbies (OR = 2.97), having a family dentist (OR = 2.34) and consulting a dentist as soon as symptoms occurred (OR = 1.74) were significantly associated with number of retained teeth in females. Factors that were significantly associated with tooth loss in both males and females included alcohol consumption (OR = 11.96, males, OR = 3.83, females), swollen gums (OR = 1.93, males, OR = 3.04, females) and toothache (OR = 3.39, males, OR = 3.52, females).
Behavioral factors that were associated with tooth retention were frequency of eating snacks between meals, tooth brushing frequency, having one's own toothbrush, smoking and drinking habits, having hobbies, having a family dentist and when they had dental treatment. Clinical factors included bleeding gums, swollen gums, and toothache.

ABSTRACT: It is important for people to maintain an appropriate lifestyle through out life to enjoy a healthy life. We have already developed a health check questionnaire, "8020 Oral Healthiness Score", in an endeavor to help people aged 80 keep more than 20 teeth. The health check consists of ten questions chosen from our previous residents' study. Named the "Sawayaka Score" it has been in use since 1999. In the present study, we focused on the results of a three-year follow-up to determine whether the Score may predict tooth loss for screening purposes.
A total of 716 village residents who participated in medical and dental checkups in 1999 as the baseline year were followed in T village of Aichi-Prefecture. The total numbers of teeth lost were examined after 1-, 2- and 3-years and odds ratios with 95% confidence intervals (CI) were generated for analysis of screening.
At the 1999 baseline, the average number of retained teeth was 23.7 +/- 6.2 (mean +/- standard error) (23.0 +/- 6.8 in males, and 24.4 +/- 5.5 in females), and the average oral health score (mean +/- standard error) was 13.1 +/- 3.9 points (12.8 +/- 4.0 in males, 13.4 +/- 3.9 in females). A low score of 4-8 at the baseline predicted major tooth loss, while an average score was associated with loss of only one or 2 teeth loss in the residents. The present study confirms that persons with a favorable lifestyle tend to retain more teeth.
It can be concluded that the 8020 Oral Healthiness Score is a useful tool to support residents' oral health promotion and predict tooth loss.
