Hiroshima University-Dental Behavioral Inventory Score Research Articles

Self reported dental health attitude and behavior of dental students in India

The aim of the present study was to evaluate the oral health attitudes and behavior of undergraduate dental students in India according to age, sex and level of dental education, and to compare it with those of other countries with different socioeconomic conditions. A self-administered questionnaire based on the Hiroshima University - Dental Behavior Inventory (HU-DBI) was distributed among 372 dental students at Darshan Dental College and Hospital (DDCH). The response rate was 75.8% with 44% males and 56% females. The mean HU-DBI score showed a significant relationship (P < 0.05) with age by one way-analysis of variance (ANOVA). The students were considerably concerned about the appearance of their teeth and gums and halitosis. The total mean score was not markedly higher in the clinical years (years 3 and 4) than in the non-clinical years (years 1 and 2), indicating that the students were almost equally aware. Although there were no statistically significant differences in gender and academic year for the mean score of HU-DBI, the present study showed that dental students in India generally had poorer oral health awareness compared to several other countries. The oral health behavior of Indian dental students has to be improved in order to serve as a positive model for their patients, family, and friends.

The Relationship Between Dental Caries Status and Oral Health Attitudes and Behavior in Young Israeli Adults

The aim of this study was to investigate the epidemiologic relationship between oral health attitudes and behavior as measured by the Hiroshima University-Dental Behavioral Inventory (HU-DBI) and dental caries status using the DMF in a sample of young Israeli adults. The HU-DBI (in Hebrew) was used to survey 123 young Israeli army recruits (eighteen and nineteen years old). All participants submitted to a clinical and radiographic dental examination. Dental caries status was evaluated using the World Health Organization (WHO) caries diagnostic criteria for decayed, missing, and filled teeth and surfaces (DMFT and DMFS, respectively). Data were statistically analyzed. DMFT and DMFS scores, which measure dental disease, ranged from 0 to 24 (average 6.77) and from 0 to 48 (average 10.95), respectively. There were sixteen (13 percent) caries free (DMF=0) participants. When relating the different DMF values to the HU-DBI responses, a statistically significant relation was found between seven items and DMF scores or their components and indices. The HU-DBI score ranged from 2 to 9 (mean 5.8, SD=1.5). Low DS and DT values significantly correlated with a high total HU-DBI score (p<0.05); that is, subjects with low levels of dental disease had more positive oral health attitudes and behavior. In young Israeli adults, dental disease, as measured by DMF scores or their components, were related to HU-DBI, which demonstrate the relationship of dental caries status with oral health behavior. Special emphasis should be given to improving patients' oral health attitudes and behaviors by providing patient education during treatment.

An assessment of oral self-care level among Japanese dental hygiene students and general nursing students using the Hiroshima University--Dental Behavioural Inventory (HU-DBI): surveys in 1990/1999.

The purpose of this study was to determine the differences in oral self-care levels between Japanese dental hygiene students and general nursing students in 1999, and compare them with a similar study in 1990. The examination was mainly based upon responses to a questionnaire titled "Hiroshima University--Dental Behavioural Inventory (HU-DBI)". Higher scores of the HU-DBI indicate better oral health attitudes/behaviour. The mean HU-DBI score of the 2nd-year dental hygiene students was significantly greater than that of the 2nd-year nursing students (9.56 and 6.65, respectively; p<0.001), and much higher than those of the 1st-year students at each course (dental hygiene course; 6.30, nursing course; 5.88). Except for the 2nd-year dental hygiene class, there were no significant differences in the HU-DBI score between the 1990 and 1999 subgroups of each class. About 1/3 of the 2nd-year nursing students reported a belief that they may eventually require false teeth, while 6% of the 2nd-year dental hygiene students held this belief. More than 60% of this study sample stated that they put off going to the dentist until they had toothache. The 2nd-year dental hygiene students were more likely to have this attitude than their 1990 peers. Flossing was not popular among the nursing students in either 1990 or 1999. Although the difference in the HU-DBI score across time was not major, the variation in HU-DBI and the favourable attitudes/behaviour toward oral health appeared to reflect the differences in schooling between student hygienists and student nurses.

Cross-cultural differences of self-reported oral health behaviour in Japanese and Finnish dental students

To determine whether any differences existed in dental health behaviour between Japanese and Finnish dental students. Hiroshima University School of Dentistry and the University of Helsinki. Comparison of cross-cultural differences of self-reported oral health behaviour. Dental students, 337 in Japan and 113 in Finland. Subjects were surveyed using the Japanese and Finnish versions of a 20-item questionnaire entitled Hiroshima University--Dental Behavioural Inventory (HU-DBI). Only 2 per cent of Finnish students reported that they put off going to the dentist until they had toothache, compared to 56 per cent of Japanese students. Similarly, significantly more Japanese students thought that their teeth were getting worse despite their daily brushing, compared to their Finnish peers. The mean HU-DBI score of Year 1 Finnish students was higher than that of their Japanese peers, which suggested a higher level of dental health awareness in Finnish students upon entry into dental school. The mean scores of the Japanese students were lower than those of their Finnish peers until Year 3. The mean scores of Year 5 and Year 6 Japanese students were higher than that of Year 1 students, indicating raised self-care levels influenced by the course in preventive dentistry. The gender difference of the HU-DBI score was not a major feature in either country. Self-reported oral health behaviours seemed to be very different between the two countries, which reflected different culture and/or health education systems of the students.

A comparison of self‐reported dental health attitudes and behavior between selected Japanese and Australian students

To compare cross-cultural differences of dental health behavior, 376 dental students in Japan and 213 in Australia were surveyed using a twenty-item Hiroshima University-Dental Behavior Inventory (HU-DBI) questionnaire (in Japanese and English versions respectively). The mean DBI score of Year 1 Australian students was significantly greater than that of their Japanese peers (Australian 6.56, Japanese 5.57; P < 0.001), which suggested a higher level of dental health awareness in Australian students on entry. Only 7 percent of the Japanese students had been told by their dentist that they were performing a high level of plaque control, as contrasted with 50 percent of the Australian students. Furthermore, while only a small proportion of the Australian students (8 percent) reported a belief that they may eventually require dentures, 37 percent of the Japanese students held this belief (P < 0.001). The mean HU-DBI score of the Japanese students was lower than that of the Australian students until Year 4. Differences between the genders were not a major feature.
