Estonian Dental Students' Oral Health-Related Knowledge, Attitudes and Behaviours (KAB): National Survey-Based Study

Evaluation of Self-Reported Oral Health Attitudes and Behavior of Dental Students in Antalya, Turkey

Background Dental students are expected to play a critical role in the oral health education of society as future providers of dental care, and their attitudes on this subject have a possible impact on the awareness of patients regarding the importance of preventing oral diseases and improving oral health. This study aimed to evaluate the oral health attitudes and behavior of dental students. Methodology The Turkish version of the Hiroshima University Dental Behavior Inventory (HU-DBI) questionnaire regarding oral health attitudes and behaviors with an additional nine questions was distributed among 250 native Turkish-speaking dental students at the Faculty of Dentistry in Antalya, Turkey. The validity of the nine questions added to the original questionnaire was evaluated by expert opinion and a pretest method. A self-administered questionnaire was used for data collection. The Mann-Whitney U test and chi-square test were used for statistical analysis, and the statistical significance level was set at p-values <0.05. Results The mean age of the 250 students in the study was 20.96 ± 1.66 years. In total, 157 (62.8%) students were preclinical (first, second, and third year) dentistry students, and 93 (37.2%) students were clinical (fourth and fifth year) dentistry students. The mean HU-DBI score of all students was 5.95 ± 1.65, and the mean HU-DBI score of clinical students (6.42 ± 1.65) was significantly (p < 0.05) higher than that of preclinical students (5.67 ± 1.59). The mean HU-DBI score of male and female students was 5.63 ± 1.55 and 6.24 ± 1.69, respectively, and this difference was statistically significant (p < 0.05). The study showed significant improvement in the behavior and attitude regarding the oral health of the clinical dental students compared with the preclinical dental students. Conclusions Among dental students, clinical students and female students had generally better attitudes and behaviors about oral health self-care compared to preclinical students and male students, respectively.

Development and Initial Validation of the Oral Health Activities Questionnaire

Background: The purpose of this study was to introduce a new Oral Health Activities Questionnaire (OHAQ, hereinafter) that examines different activities and behaviours related to the oral hygiene regimen of each analysed subject. Methods: A sample of 658 students was analysed to determine the OHAQ scale’s basic metric characteristics. To determine the construct validity of the OHAQ, descriptive statistics and correlation analysis, as well as differences testing, were applied to groups of subjects on the basis of self-reported oral status measures. Results: The dimensions of oral health activities were determined, and the scales for their measurement were constructed. Females and males differed in the OHAQ questionnaire measures. Significant but low intercorrelations were found among the measures. In the female and male subsample, four different oral health (OH, hereinafter) types of subjects were identified, exhibiting different characteristic behaviours regarding oral health. OHAQ scales showed good discriminant validity, revealing the differences related to specific self-reported oral status measures (e.g., frequency of toothache and the number of filled teeth). Conclusions: The OHAQ represents a satisfactory measurement instrument for determining the level of OH activities and for doing quick and reliable classifications of the participating subjects according to their OH activities and behaviours. The process of further validation and advancements of the OHAQ scales and measures should be continued through a clinical examination of subjects.

Czech and Slovak Dental Students' Oral Health-Related Knowledge, Attitudes, and Behaviours (KAB): Multi-Country Cross-Sectional Study

Dentists play a key role in the primary prevention of oral diseases and related systemic complications; therefore, their views on behavioural interventions need to be aligned with the current agendas for oral health. Likewise, dental students’ oral health-related knowledge, attitudes, and behaviours (KAB) are of practical importance, as they are the future opinion leaders for oral health in their respective communities. A cross-sectional survey-based study was designed to evaluate the oral health KAB of dental students in both the Czech Republic and Slovakia. The study utilized translated versions of the Hiroshima University Dental Behavioural Inventory (HU-DBI), and it aimed to recruit students from all Czech and Slovak dental schools. A total of 487 students were included in this study, out of which 372 (76.4%) were females, 271 (55.6%) were enrolled in preclinical years, 68 (14%) reported smoking tobacco at least once a week, and 430 (88.3%) reported problematic internet use. The mean HU-DBI score of Czech and Slovak dental students (8.18 ± 1.80) was comparable with the previously reported scores of dental students in Nordic and Western European countries. Czech students (9.34 ± 1.29) had a significantly higher score than their Slovak counterparts (7.56 ± 1.73). In both countries, preclinical students (8.04 vs. 8.35), the students who reported tobacco smoking (7.63 vs. 8.27), and those who reported problematic internet use (8.11 vs. 8.70) had significantly lower HU-DBI scores than their counterparts, respectively. In the Czech Republic, the significant increases in HU-DBI scores occurred after the first academic year when the students received preventive dentistry courses; therefore, one can put forward that early implementation of preventive elements in undergraduate dental curricula may yield better and more sustainable oral health gains for the students. Future research on Czech and Slovak dental curricula need to re-evaluate the oral hygiene and anti-smoking components and their impact on students’ views and attitudes.
