Associations between dental knowledge, source of dental knowledge and oral health behavior in Japanese university students: A cross-sectional study

Effects of social support on oral health behavior: Serial multiple-mediator model

OBJECTIVE

This study investigates the serial multiple mediation of job stress and perceived behavioral control (PBC) in the relationship between social support and oral health behavior (OHB).

MATERIALS AND METHODS

This cross-sectional study was conducted in Minhang District, Shanghai, China, between July and November 2021. 559 Employees from 10 community health centers were recruited. A five-part survey was used to collect data on demographic characteristics, social support, job stress, PBC and OHB. Descriptive statistics, independent-sample t-test, Pearson's correlation analysis, ordinary least-squares regression and the bootstrap method were used to analyze data.

RESULTS

Social support was found to impact OHB through three significant mediation pathways: the pathway through job stress (point estimate = 0.033; 95%BC CI [0.004, 0.089]), the pathway through PBC (point estimate = 0.283; 95%BC CI [0.174, 0.416]), and the serial multiple mediating pathway through first job stress and then PBC (point estimate = 0.006; 95%BC CI [0.001, 0.019]).

CONCLUSION

This study indicates that job stress and PBC play a serial multiple-mediator role in the relationship between social support and OHB. To ensure the effectiveness of social support intervention on OHB, workplace managers and employees should strengthen the motivators that could promote the reduction of job stress and the improvement of PBC.

Oral hygiene behaviour and its determinants among preparatory school students in Gondar city, Northwest Ethiopia: A cross-sectional study

OBJECTIVES

This study aimed to evaluate oral hygiene behaviour and its determinants among preparatory school students in Gondar city, Northwest Ethiopia.

METHODS

Institutional-based cross-sectional study was conducted among 423 students to evaluate their oral hygiene behaviour and determinant factors (sociodemographic attributes, oral hygiene knowledge, and attitude to oral hygiene behaviours). Linear regression was employed to identify factors associated with oral hygiene behaviour. A p-value of <0.05 and a 95% confidence interval were used to declare statistical significance.

RESULTS

A total of 407 students participated with a response rate of 96.2%. The mean age of the participants was 18 (SD ±1.3). The mean oral hygiene behaviour (OHB) score was about 7.89 ± 3.43. Only 9.2%, 21.4%, and 5.7% were brushing their teeth at least twice a day, cleaning their tongue, and flossing at least once a day respectively. Father's educational status (able to read and write (β = 1.99, 95% CI: 0.62, 3.38), completed secondary school (β = 1.68, 95% CI: 0.18, 3.18), and diploma and higher (β = 1.75, 95% CI: 0.33, 3.18)), being from private school (β = 3.25, 95%CI: 2.30, 4.19), knowledge about OHB (β = 0.16, 95% CI: 0.01, 0.30), and attitude towards OHB (β = 0.11, 95% CI: 0.08, 0.14) were significant factors positively associated with better oral hygiene behaviour.

CONCLUSION

Oral hygiene behaviour was poor among preparatory school students in Gondar city. Father's educational status, students' oral hygiene knowledge, and attitude were found to be significant factors affecting students' oral hygiene behaviour. Thus, tailored school-based oral health communication programs are highly required to improve students' oral hygiene behaviour.

Relationship between risk of oral frailty and awareness of oral frailty among community-dwelling adults: a cross-sectional study

We aimed to investigate the relationship between the risk of oral frailty and awareness of oral frailty among Japanese adults in an adult dental health field study conducted in Kanagawa Prefecture. Questionnaire data from a total of 5051 individuals (1907 males, 3144 females; mean age; 59.9 years) were used. The risk of oral frailty was assessed using the Oral Frailty Index-8. Of the participants, 1418 (28.1%) had a high risk of oral frailty and 1495 (29.6%) had knowledge of oral frailty. Logistic regression analysis indicated that the risk of oral frailty was significantly associated with awareness of oral frailty. We further found that awareness of oral frailty was significantly related to gender (female), age (20-39 compared to 70-79, ≥ 80), residential areas (Yokohama compared to Kawasaki, Sagamihara), exercise habits (yes), eating a balanced diet (yes), consciousness of oral health (yes), risk of oral frailty (low) and outpatient category (hospital visit). For groups with low levels of awareness obtained from the results of this study, it is necessary to consider the means of accessibility and increase awareness further.

Disparity in access for people with disabilities to outpatient dental care services: a retrospective cohort study

BACKGROUND

People with disabilities face difficulties in oral health management and gaining access to dental care. The availability of a regular source of dental care (RSDC) is an important factor that influences the access to health services and care management. The purpose of this study was to determine the effect of the availability of RSDC on the number of annual dental visits and dental expenses per visit among people with disabilities.

METHODS

Data of 7,896,251 patients with dental problems in South Korea were analyzed using the 2002-2018 National Health Insurance claims data. A generalized estimating equation was applied to analyze the repeated-measurement data, and the interaction effect between RSDC and the disability severity was evaluated.

RESULTS

The number of annual dental visits was higher among people with (2.62) than among those without (2.23) disabilities. Despite their increased dental needs, both annual dental visits and dental expenses per visit were low among older individuals (p < 0.001). The proportion and frequency of annual dental visits was lower among women than among men with disabilities. RSDC had differential effects on the severity of disability. Compared to people without disabilities, RSDC increased the number of annual dental visits (p = 0.067) and the dental expenses per visit (p < 0.05) among those with severe disabilities, but the effect on the number of annual dental visits was not significant among those with mild disabilities (p = 0.698).

CONCLUSIONS

Our results suggest a need for a special dental care system for people with disabilities, to ensure an RSDC, particularly for women and for older people with disabilities.

Oral Hygiene Practices and Oral Health Knowledge among Students in Split, Croatia

Background: Knowledge of oral health is a fundamental prerequisite for healthy behavior, allowing individuals to take measures to protect their overall health. This cross-sectional study aimed to examine the knowledge of oral health as well as to assess the oral hygiene habits among healthcare and non-healthcare students. Methods: The study was based on a questionnaire and was conducted among 1088 students. Most of the students, 67.6% were non-healthcare students. Data were processed by Mann–Whitney or Kruskal–Wallis one-way ANOVA test. Results: The correct median score and interquartile range were 11 (9–13) for all surveyed students, 11 (9–12) for students in non-healthcare programs and 13 (11–14) for students in healthcare programs. Students did not significantly differ in the knowledge of oral health by gender (p = 0.082) but did differ by age, study program, and year of study (p ≤ 0.001). Students whose family members work in the field of dental medicine also showed better oral health knowledge (p ≤ 0.001). Conclusion: The results showed good oral health knowledge among tested university students. However, it is important to emphasize that students who showed better knowledge more often used additional aids to maintain oral hygiene; therefore, the obtained data underline the importance of students’ further education in order to better understand and maintain oral health.

Oral self-care behavior and its influencing factors in a sample of school children from Central Iran

BACKGROUND

Oral health is an important part of public health and crucial to health promotion and enhancing the quality of life. This research examined childhood oral self-care behavior and their related factors using extended Theory of Planned Behavior (TPB).

METHOD

This cross-sectional study was conducted on 368 sixth-grade elementary school students in Saveh city, Iran, in 2019. The students were selected using a random multi-stage sampling method. The instrument included the socio-demographic questions, TPB constructs, and action and coping plan items. Data were analyzed by SPSS software (Version 21) at alpha level p ≤ 0.05.

RESULT

Overall, 24 (6.6%) students have never used toothbrushes, 222 (62.7%) have never used dental floss, and 298 (82.7%) students have never used mouthwash. The stepwise multiple linear regression analysis results indicated that the TPB with action and coping planning constructs had better predictive power than the original model. In the final model, coping planning (β = .28), intention (β = .24), action planning (β = .23), and perceived behavior control (β = .15) were the most important predictors of oral self-care behavior.

CONCLUSION

The results indicated that the oral self-care behavior status in Iranian elementary students was not favorable, and the extended model of the TPB with action and coping plan constructs were significant predictors of self-care behavior. Therefore, these findings emphasize the need for expanding educational interventions based on the extended model of the TPB to improve the oral self-care behavior of students.

Living with Family Is Directly Associated with Regular Dental Checkup and Indirectly Associated with Gingival Status among Japanese University Students: A 3-Year Cohort Study

Although some studies showed that lifestyle was associated with oral health behavior, few studies investigated the association between household type and oral health behavior. The aim of this prospective cohort study was to investigate the association between household type, oral health behavior, and periodontal status among Japanese university students. Data were obtained from 377 students who received oral examinations and self-questionnaires in 2016 and 2019. We assessed periodontal status using the percentage of bleeding on probing (%BOP), probing pocket depth, oral hygiene status, oral health behaviors, and related factors. We used structural equation modeling to determine the association between household type, oral health behaviors, gingivitis, and periodontitis. At follow-up, 252 students did not live with their families. The mean ± standard deviation of %BOP was 35.5 ± 24.7 at baseline and 32.1 ± 25.3 at follow-up. In the final model, students living with their families were significantly more likely to receive regular dental checkup than those living alone. Regular checkup affected the decrease in calculus. The decrease in calculus affected the decrease in %BOP over 3 years. Living with family was directly associated with regular dental checkups and indirectly contributed to gingival status among Japanese university students.

Relationship between oral hygiene knowledge, source of oral hygiene knowledge and oral hygiene behavior in Japanese university students: A prospective cohort study

The aim of this prospective cohort study was to examine whether oral hygiene knowledge, and the source of that knowledge, affect oral hygiene behavior in university students in Japan. An oral exam and questionnaire survey developed to evaluate oral hygiene knowledge, the source of that knowledge, and oral hygiene behavior, such as the frequency of tooth brushing and regular dental checkups and the use of dental floss, was conducted on university student volunteers. In total, 310 students with poor tooth brushing behavior (frequency of tooth brushing per day [≤ once]), 1,963 who did not use dental floss, and 1,882 who did not receive regular dental checkup during the past year were selected. Among these students, 50, 364, and 343 in each respective category were analyzed in over the 3-year study period (follow-up rates: 16.1%, 18.5%, and 18.2%, respectively). The odds ratios (ORs) and 95% confidence intervals (CIs) for oral hygiene behavior were calculated based on oral hygiene knowledge and the source of that knowledge using logistic regression models. The results showed that dental clinics were the most common (> 50%) source of oral hygiene knowledge, and that a more frequent use of dental floss was significantly associated with dental clinics being a source of oral hygiene knowledge (OR, 4.11; 95%CI, 1.871–9.029; p < 0.001). In addition, a significant association was seen between dental clinics being a source of oral hygiene knowledge and more frequent regular dental checkups (OR, 13.626; 95%CI, 5.971–31.095; p < 0.001). These findings suggest the existence of a relationship between dental clinics being the most common source of oral hygiene knowledge and improved oral hygiene behavior in Japanese university students.

Inclusive Oral Healthcare for a better Future Together

Oral health is a critical component to overall quality of life. Recommendations and guidelines for oral health continue to evolve while remaining underutilized worldwide. Still, oral healthcare parity and equity are achievable. This public health priority must be supported with stronger research, service delivery must be equitable and transparent, and the impact of oral healthcare must be fully understood. Data, surveillance, evidence and translation must be improved for oral health specialties as well as for greater global governance. Further, interdisciplinary coordination between orthodontic, dentistry, medical, biotechnology and research organizations must be prioritized. With dedication and consistent approach, oral healthcare can achieve the best outcomes for quality of life and cost effective public health.
