Effectiveness of educational strategies to teach evidence-based dentistry to undergraduate dental students: a systematic review.

OBJECTIVES: Evidence-based dentistry (EBD) training has been widely promoted in dental schools around the world and policymakers ask for suitable strategies to teach EBD within undergraduate dental education. The present study aims to evaluate the effectiveness of these strategies on dental students' knowledge, attitude, and skills. METHODS: PubMed, Embase, Scopus, Cochrane Central Register of Controlled Trials, and Eric databases were searched using search terms obtained from Medical Subject Headings (MeSH) terms and free text method without time restrictions, up to November 2022. The identified articles were screened based on titles and abstracts for inclusion criteria. Subsequently, relevant articles underwent data extraction. Finally, the risk of bias was assessed through Joanna Briggs Institute critical appraisal checklists. RESULTS: Twelve of 439 studies were included: nine quasi-experimental studies, two cross-sectional, and one randomized controlled trial study. Regarding the overlap among categories, six studies assessed knowledge, seven assessed attitude, and eight focused on skills or performance in EBD. Due to the heterogeneity of the interventions and results of included studies, a meta-analysis was not performed. EBD was mostly taught in small group collaborations. Interventions included lectures, workshops, seminars, small group sessions, journal clubs, online sessions, or a combination of them in various frequencies and duration. CONCLUSIONS: EBD implementation into dental curricula is improving through strategies including designing continuing and frequent dental education courses, establishing collaborative student research groups, utilizing online tools for EBD education, and dividing EBD courses into shorter modules. The systematic review protocol was registered in PROSPERO (ID: CRD42022350238).

Prevalence of Early Childhood Caries and the Related Factors among 3-5- Year-Old Children in Babol, Iran.

Statement of the Problem: Regular dental checkups to diagnose early childhood caries (ECC) are critical for maintaining and improving children's oral health and well-being. The prevalence of ECC is important for planning proper oral health programs. Purpose: This study aimed to investigate the prevalence of ECC and its related factors in children aged 3 to 5 years at Babol, Iran. Materials and Method: This cross-sectional study was conducted on 280 children aged 3-5 years in the kindergartens of Babol. Children were examined for dental caries according to World Health Organization criteria. The variables such as age, gender, health, nutritional habits, parents' educational level, parents' job status, and level of dental care were recorded in the questionnaire. Data were analyzed using t-test, chi-square and ANOVA and p< 0.05 was considered significant. Results: Average decayed-missing-filled teeth (dmft) were 4.03±3.6 and 73.2% in children with ECC, while 26.8% were caries-free. A significant association was found between age, snack consumption, father's education, mother's job, nocturnal drinking milk, tooth-brushing, and a history of dental check up before age 2 with ECC. Conclusion: The results of this analysis showed a high prevalence of ECC in Babol. Therefore, educational and interventional programs in prevention and dental health care, especially for mothers, nurses, and teachers of these age groups, should be considered.

Pediatric patients' reasons for visiting dentists in all WHO regions.

BACKGROUND: Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the four oral health-related quality of life (OHRQoL) dimensions (4D) or areas in which oral disorders impact pediatric patients. Using their dentists' assessment, the study aimed to evaluate whether pediatric dental patients' oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct. METHODS: Dentists who treat children from 32 countries and all WHO regions were selected from a web-based survey of 1580 international dentists. Dentists were asked if their pediatric patients with current or future oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct. Proportions of all pediatric patients' oral health problems and prevention needs were computed. FINDINGS: Data from 101 dentists treating children only and 523 dentists treating children and adults were included. For 90% of pediatric patients, their current oral health problems fit well in the four OHRQoL dimensions. For 91% of oral health problems they intended to prevent in the future were related to these dimensions as well. Both numbers increased to at least 96% when experts analyzed dentists´ explanations of why some oral health problems would not fit these four categories. CONCLUSIONS: The study revealed the four fundamental components of dental patients, i.e., the four OHRQoL dimensions (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact) are also applicable for pediatric patients, regardless of whether they have current or future oral health concerns, and should be considered when measuring OHRQoL in the pediatric dental patient population.

Why Patients Visit Dentists - A Study in all World Health Organization Regions.

OBJECTIVE: The dimensions of oral health-related quality of life (OHRQoL) Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the major areas where patients are impacted by oral diseases and dental interventions. The aim of this study was to evaluate whether dental patients' reasons to visit the dentist fit the 4 OHRQoL dimensions. METHODS: Dentists (N = 1580) from 32 countries participated in a web-based survey. For their patients with current oral health problems, dentists were asked whether these problems were related to teeth, mouth, and jaws' function, pain, appearance, or psychosocial impact or whether they do not fit the aforementioned 4 categories. Dentists were also asked about their patients who intended to prevent future oral health problems. For both patient groups, the proportions of oral health problems falling into the 4 OHRQoL dimensions were calculated. RESULTS: For every 100 dental patients with current oral health problems, 96 had problems related to teeth, mouth, and jaws' function, pain, appearance, or psychosocial impact. For every 100 dental patients who wanted to prevent future oral health problems, 92 wanted to prevent problems related to these 4 OHRQoL dimensions. Both numbers increased to at least 98 of 100 patients when experts analyzed dentists' explanations of why some oral health problems would not fit the four dimension. For the remaining 2 of 100 patients, none of the dentist-provided explanations suggested evidence against the OHRQoL dimensions as the concepts that capture dental patients' suffering. CONCLUSION: Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact capture dental patients' oral health problems worldwide. These 4 OHRQoL dimensions offer a psychometrically sound and practical framework for patient care and research, identifying what is important to dental patients.

Validation and evaluation of the Mandarin version of the oral health literacy adult questionnaire in Taiwan.

OBJECTIVES: This study aimed to translate the Oral Health Literacy Adult Questionnaire into a Mandarin version (MOHL-AQ) and to examine its psychometric properties. METHODS: A methodological research using psychometric testing and evaluation of a translated instrument. A convenience sample of 402 participants from northern Taiwan were recruited for the validation of the MOHL-AQ. Internal consistency reliability, split-half reliability, inter-rater reliability, face validity, content validity, and construct validity were evaluated. RESULTS: The value of internal consistency and split-half reliability of the MOHL-AQ were 0.77 and 0.78, respectively. Content validity reported a high content validity index (CVI = 95%). Exploratory factor analysis (EFA) and parallel analysis (PA) were used to determine a unidimensional model and confirmatory factor analysis (CFA) was employed to confirm the model. The indices of good fit model were achieved at GFI = 0.93, AGFI = 0.92, RMSEA = 0.04, CFI = 0.90, PGFI = 0.73, χ2 /df = 1.86 (p < .001). Most of the item-total correlations indicated adequate and acceptable convergent validity (r > .30). CONCLUSION: MOHL-AQ demonstrates adequate psychometric properties for measuring the oral health literacy in Mandarin-speaking population. Public health nurses can use MOHL-AQ to assess oral health literacy in the community settings and further screen potential population with inadequate oral health literacy.

Comparison of the Effect of Toothbrushing Education Via Video, Lecture and Pamphlet on the Dental Plaque Index of 12-Year-Old Children.

The aim of this study was to compare the effect of different modes of toothbrushing education (lecture, video and pamphlet) on the dental plaque index (PI) of adolescents. The cluster randomized intervention was performed on 128 participants aged 12 years, who were allocated into four groups based on the type of intervention. Group 1: no intervention; and groups 2, 3, 4: education via lecture, video, and pamphlet, respectively (n = 32). Their plaque index was measured at the baseline, 24 h and two months later. Data were analyzed by repeated measures analysis of variance (ANOVA), one-way ANOVA, independent and paired t-test. The plaque indices of groups 2, 3, 4 at 24 h (p values < 0.001) and two months (p values < 0.001) showed a significant reduction when compared to the baseline. The lowest PI score was observed in the pamphlet, video and lecture groups at 24 h, respectively. After 2 months, the lowest score of PI was measured in lecture, video and pamphlet groups, respectively; however, these differences were non-significant. Therefore, toothbrushing education via lecture, video and pamphlet reduced the dental plaque index with the same effectiveness.

Determinants of oral health: does oral health literacy matter?

Objective. To evaluate oral health literacy, independent of other oral health determinants, as a risk indicator for self-reported oral health. Methods. A cross-sectional population-based survey conducted in Tehran, Iran. Multiple logistic regression analysis served to estimate the predictive effect of oral health literacy on self-reported oral health status (good versus poor) controlling for socioeconomic and demographic factors and tooth-brushing behavior. Results. In all, among 1031 participants (mean age 36.3 (SD 12.9); 51% female), women reported brushing their teeth more frequently (P < 0.001) and scored higher for oral health literacy (mean 10.9 versus 10.2, P < 0.001). In the adjusted model, high age (OR = 1.01, 95% CI 1.003-1.034), low education (OR = 1.88, 95% CI 1.23-2.87), small living area in square meters per person (OR = 1.85, 95% CI 1.003-3.423), poor tooth brushing behavior (OR = 3.35, 95% CI 2.02-5.57), and low oral health literacy scores (OR = 1.58, 95% CI 1.02-2.45) were significant risk indicators for poor self-reported oral health. Conclusions. Low oral health literacy level, independent of education and other socioeconomic determinants, was a predictor for poor self-reported oral health and should be considered a vital determinant of oral health in countries with developing health care systems.
