Oral health literacy and its association with oral health-related quality of life amongst pregnant women: a cross-sectional study.

PURPOSE: This study aimed to evaluate the association of oral health literacy (OHL) and oral health-related quality of life (OHRQoL) of pregnant women. METHODS: This cross-sectional study evaluated a representative sample of pregnant women assisted in public health services in southern Brazil. Demographic, socioeconomic, psychosocial and behavioural data were collected through structured questionnaires. The Oral Health Impact Profile (OHIP-14) questionnaire was used to evaluate the OHRQoL. The Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) was used to measure OHL. Dental caries and gingival bleeding were evaluated by clinical examinations. Adjusted multilevel Poisson regression models with a hierarchical approach were used to assess the associations. The results are presented as rate ratio (RR) and 95% confidence interval (95% CI). RESULTS: A total of 520 pregnant women were evaluated. Pregnant women with lower levels of OHL presented overall OHIP-14 scores 14% higher (RR 1.14; 95% CI 1.07-1.22) than their counterparts. High household income and high education level were related to low overall OHIP-14 scores. Furthermore, less dental attendance, low social support, untreated dental caries and gingival bleeding were also associated with high overall OHIP-14 scores. CONCLUSION: Our findings reinforce that health literacy levels influence patient-reported outcomes. Pregnant women with lower OHL were more likely to present poorer OHRQoL.

Does health literacy mediate the relationship between socioeconomic status and health related outcomes in the Belgian adult population?

BACKGROUND: Health literacy (HL) has been put forward as a potential mediator through which socioeconomic status (SES) affects health. This study explores whether HL mediates the relation between SES and a selection of health or health-related outcomes. METHODS: Data from the participants of the Belgian health interview survey 2018 aged 18 years or older were individually linked with data from the Belgian compulsory health insurance (n = 8080). HL was assessed with the HLS-EU-Q6. Mediation analyses were performed with health behaviour (physical activity, diet, alcohol and tobacco consumption), health status (perceived health status, mental health status), use of medicine (purchase of antibiotics), and use of preventive care (preventive dental care, influenza vaccination, breast cancer screening) as dependent outcome variables, educational attainment and income as independent variables of interest, age and sex as potential confounders and HL as mediating variable. RESULTS: The study showed that unhealthy behaviours (except alcohol consumption), poorer health status, higher use of medicine and lower use of preventive care (except flu vaccination) were associated with low SES (i.e., low education and low income) and with insufficient HL. HL partially mediated the relationship between education and health behaviour, perceived health status and mental health status, accounting for 3.8-16.0% of the total effect. HL also constituted a pathway by which income influences health behaviour, perceived health status, mental health status and preventive dental care, with the mediation effects accounting for 2.1-10.8% of the total effect. CONCLUSIONS: Although the influence of HL in the pathway is limited, our findings suggest that strategies for improving various health-related outcomes among low SES groups should include initiatives to enhance HL in these population groups. Further research is needed to confirm our results and to better explore the mediating effects of HL.

Influence of digital health literacy on online health-related behaviors influenced by internet advertising.

BACKGROUND: The frequency of health-related information seeking on the internet and social media platforms has increased remarkably. Thus, the ability to understand and select accurate health-related information online, known as EHealth literacy, is crucial for the population. Therefore, this study aimed to evaluate how eHealth literacy influences the critical analysis of oral health-related information obtained from the Internet and its influence on oral health-related behaviors.  METHODS: A cross-sectional online study was conducted with 418 Brazilian adults who responded to the eHEALS questionnaire, with questions regarding the influence of online information on oral health decisions. Socioeconomic and demographic characteristics were also collected. RESULTS: The mean eHEALS score was 27.85 (± 8.13), with a range spanning from 8 to 40 points. Participants with higher eHEALS scores reported using social media platforms to seek for dentists and to acque information about symptoms, diagnoses, and treatments. Furthermore, this group tended not to disregard professional health recommendations based on Internet information and abstained from utilizing products promoted by digital influencers. In multivariate models, increased eHEALS scores were associated with reduced consumption of products endorsed by digital influencers. CONCLUSIONS: The findings from this study suggest that individuals with higher scores on the eHealth literacy questionnaire often conduct research on their health status and seek for health care providers on the Internet. Moreover, these individuals were less likely to be influenced by digital influencers.

What Is Health Literacy Among Orthognathic Surgery Patients?

BACKGROUND: Health literacy of orthognathic surgery patients has not been thoroughly evaluated. PURPOSE: The purpose of this study was to estimate health literacy and identify risk factors associated with inadequate health literacy in orthognathic surgery patients. STUDY DESIGN, SETTING, SAMPLE: A cross-sectional study was implemented utilizing patients ages 14-80 years who presented for orthognathic surgery evaluation between September 2021 and December 2022. Subjects were excluded from the study if they did not complete the orthognathic surgery evaluation, were not between the ages of 14-80 years old, or did not complete the Brief Health Literacy Screening Tool (BRIEF) questionnaire during intake. Subjects who have not undergone orthognathic surgery but completed the initial evaluation for orthognathic surgery were included in the study. PREDICTOR VARIABLES: The predictor variables were a set of risk factors for inadequate health literacy: age, sex, primary language, race, estimated household income, and diagnosis. MAIN OUTCOME VARIABLE: The main outcome variable was health literacy assessed using the BRIEF questionnaire. During intake, subjects completed the BRIEF questionnaire consisting of four questions scored on an ordinal scale of 1-5. Inadequate health literacy was defined as a BRIEF score ≤16. COVARIATES: Not applicable. ANALYSES: Bivariate and multivariate analyses were performed. P < .05 was considered statistically significant. RESULTS: Of 150 patients presenting for orthognathic surgery, fifteen percent of patients had inadequate health literacy via the BRIEF test. The mean age of those with adequate health literacy was 27.9 years (standard deviation, ±12.5) compared to 18.5 years (standard deviation, ±5.7) for those with inadequate health literacy (P = <.001). After adjusting for sex, language, race, estimated household income, and diagnosis via multivariate analysis, increasing age was associated with decreased odds of inadequate health literacy (adjusted odds ratio = 0.81; confidence interval, 0.72-0.92; P = <.001). CONCLUSION AND RELEVANCE: In the complex process of orthognathic surgery, it is essential to identify patients with inadequate health literacy that may require additional health literacy interventions. Ultimately, 15% of orthognathic surgery subjects had inadequate health literacy, and younger patients were the most susceptible as the odds of inadequate health literacy decreased with increasing age.

Age-related knowledge deficit and attitudes towards oral implants: Survey-based examination of the correlation between patient age and implant therapy awareness.

BACKGROUND: Implantology, as a recognized therapeutic approach, is gaining prominence. The decision-making process and success of implant therapy are closely linked to patient knowledge and expectations. This study aims to explore the association between age and knowledge regarding oral implants. METHODS: Participants were categorized into three age groups (ag): ag 1 (35-44 years), ag 2 (65-74 years), and ag 3 (75 years and older). A total of 400 participants per age group were randomly selected using data from the residents' registration office of Berlin, Germany. Structured telephone interviews were conducted between 2016 and 2017, employing a 67-item questionnaire covering awareness, information level, cost estimation, attitudes, and experiences with oral implants. RESULTS: Despite a low overall knowledge level across all age groups, there was no significant correlation between age and knowledge about oral implants. Awareness increased with age. Information sources varied, with friends, acquaintances, and dentists playing key roles. Participants expressed diverse opinions on implants, with durability and stability identified as crucial characteristics. Significant differences in knowledge were observed between age groups regarding awareness, information sources, and perceptions of dentists offering implants. CONCLUSIONS: The study suggests a need for targeted educational programs, emphasizing age-appropriate information sources to enhance health literacy in oral implantology, particularly among older individuals. Educating physicians on oral implant basics is also crucial. Implementing these measures could empower individuals to make informed decisions about oral implant treatment, thereby contributing to improved oral health outcomes.

The relationship between dental anxiety and oral health literacy with oral health-related quality of life.

BACKGROUND AND AIM: Dental anxiety is a prevalent issue in society, characterized by an uneasy sensation and anticipation of negative experiences in dental settings. In essence, dental anxiety, oral health literacy, and quality of life may have a relationship with each other, however, there is a shortage of evidence examining the interplay between these factors. Therefore, this study aimed to assess the relationship between dental anxiety and oral health literacy (OHL) with oral health-related quality of life (OHRQOL). METHODS: This is an analytical cross-sectional study conducted on 155 patients referred to the Department of Oromaxillofacial Diseases. Three questionnaires consisting of dental anxiety scale, oral health impact profile- 14, and oral health literacy adult questionnaire were used to measure anxiety, health literacy, and the quality of life-related to oral health. Scores were recorded and analyzed by IBM SPSS 24 software using independent samples T-test and ANOVA. Besides, the confirmatory modeling through the goodness of fit index of the model was applied. RESULTS: This study involved 155 participants, with a mean age of 38.44 ± 14 years. The majority were females, comprising 99 individuals (63.9%). In this study, 89 patients (57.4%) had dental anxiety. The mean OHL score in the examined participants was 9.88 ± 3.97. Both factors of anxiety (p < 0.001) and OHL (p = 0.012) had a significant effect on the OHRQOL. There was no significant difference in the mean OHRQOL among the three categories of OHL (p = 0.085). The confirmatory modeling showed that only the fourth (p = 0.065) and fifth (p = 0.146) questions of the OHL questionnaire had no significant effect on the total score of OHL. Besides, both factors of anxiety (p < 0.001) and OHL (p = 0.012) had a significant effect on OHRQOL. With an increase of one unit in anxiety, the OHRQOL score increases by 0.31 and for a one-unit increase in the OHL score, the OHRQOL score decreases by 0.66 units. CONCLUSION: In conclusion, it seems that considering various dimensions of oral and dental health can help patients to have reduced psychological anxiety. Notably, further multicenter studies assessing diverse variables related to dental anxiety, OHL, and OHRQOL, and considering more comprehensive study designs with longitudinal follow-up could help provide insights into how changes in dental anxiety and OHL over time affect OHRQOL.

Validation of an Arabic version of the short form of the health literacy in dentistry scale: a cross-sectional study.

BACKGROUND: The Arabic version of the short form of the Health Literacy in Dentistry scale (HeLD) had not yet been developed in previously published studies. This study aims to test the reliability and validity of an Arabic version of the short form of the HeLD questionnaire. METHODS: The short version of HeLD was translated into Arabic and the psychometric properties were evaluated in a sample of 1,889 female students in their first year of secondary school. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC), and internal consistency reliability was assessed using Cronbach's alpha. Content validity was investigated by creating a correlation matrix between the individual items of the HeLD-14, and criterion validity was determined using Pearson's correlation between the HeLD-14 score and an overall oral health rating. Sensitivity analysis was assessed by testing the associations of the HeLD-14 score with oral health-related behaviours and residential area. RESULTS: The Arabic version of HeLD-14 (A-HeLD-14) had acceptable ICC (0.54) and excellent internal consistency (Cronbach's alpha: 0.92). The correlations between the items of the A-HeLD-14 varied from 0.3 to 0.9. The A-HeLD-14 showed a statistically significant correlation with the overall oral health rating (r = 0.37, p < 0.001). The median A-HeLD-14 score was significantly higher in participants who brushed their teeth frequently (51.31), visited the dentist regularly (52.00), consumed fresh fruit frequently (51) and consumed soda or energy drinks infrequently (51.00) than participants who brushed their teeth infrequently (41.50), visited the dentist irregularly (49.00), consumed fresh fruit infrequently (47) and consumed soda or energy drinks frequently (48.00). CONCLUSION: The A-HeLD-14 instrument demonstrates sufficient validity, reliability, and sensitivity for measuring oral health literacy among the Arabic-speaking population.

The impact of parental dental anxiety and oral health literacy on child oral health and dental-visit patterns: a cross-sectional study.

BACKGROUND: Identifying the risk indicators of parental dental anxiety (PDA) and oral health literacy (OHL) can help oral healthcare professionals recognise challenges in this field. Armed with the appropriate information, they can effectively engage with parents to build trust and promote early and regular child dental visits. OBJECTIVES: This study aimed to investigate the association between PDA and OHL with the sociobehavioural characteristics of families, self-reported child oral health (presence of ≥ 1 untreated decayed teeth) and the dental visit patterns amongst children living in Al Jouf Province, Kingdom of Saudi Arabia. SUBJECTS AND METHODS: A total of 430 parents with children aged ≥ 14 years were invited using a systematic random sampling method. PDA was assessed using the Dental Anxiety Scale-Revised (DAS-R) scale, and parents' OHL was measured using the Rapid Estimate of Adult Literacy in Dentistry-30 (REALD-30). The relationships amongst participant characteristics, PDA and OHL were evaluated through the Chi-square and ANOVA. Additionally, binary regression analysis was conducted to identify predictor variables associated with PDA and OHL. A P value of < 0.05 was considered statistically significant. RESULTS: Children with ≥ 1 untreated decayed tooth were 2.5 times more likely to have PDA (95% confidence interval [CI] = 1.37, 4.37). Children who visited the dentist in < 6 months had 93% lower likelihood to have PDA (adjusted odds ratio (AOR) = 0.07; 95% CI = 0.03, 0.18). Parents aged 20-25 years were 81% less likely to have OHL than those above 30 years (AOR = 0.19; P = 0.038). Similarly, parents with medium family income were 52% less likely to have OHL than the high-income group (AOR = 0.48; P = 0.013). Finally, parents of children who visited the dentist within < 6 months were 34 times more likely to have OHL than those whose children visited the dentist > 12 months ago (AOR = 34.94; P < 0.001). CONCLUSION: PDA and OHL were significantly affected by parental age, family income, the presence of ≥ 1 untreated decaying tooth and the child dental visit patterns. During a child's first dental visit, paediatric dentists should always assess the PDA, OHL and sociobehavioural characteristics of a family by using appropriate scales and semistructured interviews.

Validation of an online version of the rapid estimate of adult literacy in dentistry-30 for use by medical and dental students in Nigeria.

BACKGROUND: The need for online adaptations of research instruments became more pronounced amidst the COVID-19 pandemic. This study sought to modify the REALD-30 for online application (eREALD-30) and evaluate its content validity and internal reliability among medical and dental students in Nigeria. METHODS: The eREALD-30 required participants to identify if each of the listed words were related to dentistry by ticking either a 'yes' or 'no' response with the option to mark 'don't know' for words they were unsure about. Scores ranged from 0 to 30. Five oral health experts reviewed the eREALD-30 for cultural appropriateness, while content validity was evaluated by 10 medical and dental students. Internal reliability was assessed with 320 students recruited from 15 medical and dental schools spanning the country's six geopolitical zones. These students also completed an oral health status assessment tool. Data collection utilized an online survey platform. Validity of the eREALD-30 was determined through correlation analysis between eREALD-30 scores and the oral health status assessment tool. Furthermore, binary logistic regression analysis was employed to explore the assocations between participants' oral health status and their oral health literacy, adjusting for age, sex, and level of medical and dental education. RESULTS: Out of the respondents, 178 (55.6%) exhibited poor oral health literacy, while 205 (64.1%) reported having good oral health status. Those with good oral health literacy demonstrated significantly higher odds of having good oral health status (OR: 1.61; 95% CI: 1.02-2.54; p = 0.04). However, individuals with good oral health literacy had increased odds of good oral health status after adjusting for confounding factors,, though this association did not retain statistical significance (AOR: 1.39; 95% CI: 0.86-2.24; p = 0.17). The eREALD-30 displayed strong internal consistency (Cronbach alpha = 0.933), indicating its reliability in assessing oral health literacy levels, alongside a high content validity score of 0.90. CONCLUSION: The study finding suggests that the e-version of the REALD-30 was reliable and valid for use among medical and dental students in Nigeria.

Oral health knowledge, literacy and behavior of pregnant women: a qualitative study in a northeastern province of Thailand.

BACKGROUND: Pregnancy is a unique period of women's lives, and oral health is an important public health indicator during this period. Pregnant women have increased vulnerability to oral health problems. The study aimed to describe oral health knowledge, literacy and behavior of pregnant women in a northeastern province of Thailand. METHODS: A descriptive study was used. Twenty pregnant women who attended antenatal care clinics of eight public hospitals in the province were recruited by use of purposive sampling. They participated voluntarily in individual interview. The Health Belief Model was used as conception framework. All data were transcribed and subjected to content analysis. RESULTS: Five categories emerged: Misbelief and lack of knowledge, Oral health problems and dental care seeking, Oral health information from different persons, Self-care management of oral health, and Fear of and anxiety towards dental treatment. The findings showed that low knowledge of need for treatment, little importance to oral health and low priority of dental needs affect the demand for dental care. Fear of and anxiety towards dental treatment were the results of negative past experiences of neglecting dental care. Some women perceived health benefits of practicing self-care of oral health during pregnancy. CONCLUSION: The findings help to better understand the oral health issues of pregnant women and provide baseline information for oral health promotion. Such promotion and culturally appropriate care should be integrated in maternal health education classes.

Oral Health Literacy Status, Knowledge Levels, Beliefs, and Behaviors of Pregnant Women.

CONTEXT: Pregnancy may exacerbate the frequency and severity of some dental problems. However, most pregnant women avoid going to the dentist. AIMS: To examine the oral hygiene and dental care behaviors of women during pregnancy, to measure their knowledge levels, to reveal their oral and dental health literacy status, and their beliefs about treatment. SETTINGS AND DESIGN: The study was conducted for a period of 1 month with pregnant women over the age of 18 who presented to the obstetrics outpatient clinic and agreed to participate in the study and who had no known anomalies or complications. METHODS AND MATERIAL: A survey was completed by face-to-face interviews with 317 pregnant women of different ages and gestational weeks. Participants were asked questions regarding their sociodemographic characteristics, pregnancy characteristics, oral hygiene-related beliefs, behaviors, and knowledge levels. STATISTICAL ANALYSIS USED: The data obtained in the study were analyzed with SPSS 21.0 program. Since the kurtosis and skewness values were between +3 and -3, parametric tests were used. RESULTS: In total, 317 pregnant women between the ages of 18 and 43 participated in the study. The most common beliefs are listed as; babies receive the necessary calcium from the teeth, antibiotics given during dental treatment harm the baby, and panoramic radiography taken during treatment harms the baby. 91.5% of the participants did not visit the dentist after planning a pregnancy, and 89% of them did not visit the dentist during pregnancy. The most common reason not to visit the dentist is not having a dental problem. The rate of knowing that dental infections during pregnancy will affect the baby is 50.5%. CONCLUSIONS: In the present study, it is seen that pregnant women do not have adequate oral hygiene. The reasons were listed as various false beliefs and lack of sufficient knowledge. Health professionals should provide information about oral hygiene to pregnant women and direct them to the dentist.

Impact of oral health literacy and psychoactive substances on tooth loss in adolescents.

The aim of the present study was to investigate associations between tooth loss, and oral health literacy, the use of multiple psychoactive substances, and the reason for the last dental appointment in adolescents. A cross-sectional study was conducted with a representative sample of 746 adolescents aged 15-19 years in Campina Grande, Brazil. Parents/guardians answered a sociodemographic questionnaire. The adolescents answered the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30), the alcohol, smoking, and substance involvement screening test, and an oral health questionnaire from the National Oral Health Survey. The adolescents were then examined by two examiners who had undergone training and calibration exercises for the diagnosis of tooth loss due to caries (K > 0.80). Associations between variables were investigated using robust logistic regression analysis for complex samples (α = 5%). The prevalence of tooth loss was 17.4%. Oral health literacy (OR = 0.93; 95% CI: 0.89-0.97) was inversely associated with tooth loss, while multiple psychoactive substance use (OR = 2.01; 95% CI: 1.09-3.69) and last dental visit for treatment/symptoms (OR = 3.05; 95% CI: 1.73-5.36) were directly associated with tooth loss. Oral health literacy, multiple psychoactive substance use, and reason for last dental appointment exerted an influence on tooth loss among adolescents.

Associations of health literacy with dental care use and oral health status in Japan.

BACKGROUND: The concept of health literacy has gained prominence in the context of oral health. In Japan, curative dental care is generally under universal health coverage, while preventive dental care requires effort. We used this situation to test the hypothesis that high health literacy is associated with preventive dental care use and good oral health status, but not with curative dental care use, in Japan. METHODS: A questionnaire survey was conducted from 2010 to 2011 among residents aged 25-50 years in Japanese metropolitan areas. Data from 3767 participants were used. Health literacy was measured using the Communicative and Critical Health Literacy Scale, and the total score was categorized into quartiles. Poisson regression analyses with robust variance estimators were conducted to examine the associations of health literacy with curative dental care use, preventive dental care use, and good oral health, adjusted for covariates. RESULTS: The percentages of curative dental care use, preventive dental care use, and good oral health were 40.2%, 28.8%, and 74.0%, respectively. Health literacy was not associated with curative dental care use; the prevalence ratio (PR) of the highest relative to the lowest quartile of health literacy was 1.04 (95% confidence interval [CI], 0.93-1.18). High health literacy was associated with preventive dental care use and good oral health; the corresponding PRs were 1.17 (95% CI, 1.00-1.36) and 1.09 (95% CI, 1.03-1.15), respectively. CONCLUSIONS: These findings may provide clues for the design of effective interventions to promote preventive dental care use and improve oral health status.

Do sociodemographic factors influence the levels of health and oral literacy? A cross-sectional study.

BACKGROUND: Oral health literacy has gained importance in dental literature, and its relationship with oral health status and association with health status (HL) has been reported. Then, an association between the levels of HL and OHL could be expected. This study aimed to assess the levels of HL and OHL according to sociodemographic factors and to explore a possible association between HL and OHL. METHODS: The European Health Literacy Survey and Oral Health Literacy Adults Questionnaire were applied to a convenience sample from Portuguese individuals. Also, sociodemographic factors such as sex, age, schooling level of the participants and their parents, and if the participants were professionals or students of the health field were assessed. To analyze the data, the Kruskal-Wallis and Mann-Whitney U tests were used to compared sociodemographic variables and the levels of literacy in general and oral health. The Spearman correlation test assessed the correlation between the levels of HL and OHL. RESULTS: HL results showed that 45.1% of the volunteers were considered in a "problematic level" and 10.3% in "excellent level". However, 75% presented an adequate level of OHL. Regarding the levels of HL in each sociodemographic variable, significant higher levels of "excellent level" were found in health professionals and students when compared with participants not related to health area (p < 0.001). Comparisons between the levels of OHL in each sociodemographic variable showed, significant differences regarding sex (p < 0.05), age (p < 0.001), levels of schooling of the participants and their parents (p < 0.009 and p < 0.001) and relationship with health field. (p < 0.001). A significant positive - weak correlation was found between HL and OHL (p < 0.001). CONCLUSIONS: HL and OHL levels are associated and could be influenced by sociodemographic factors.

Oral health literacy, knowledge and perceptions in a socially and culturally diverse population: a mixed methods study.

BACKGROUND: Poor oral health literacy has been proposed as a causal factor in disparities in oral health outcomes. This study aims to investigate oral health literacy (OHL) in a socially and culturally diverse population of Australian adults visiting a public dental clinic in Western Sydney. METHODS: A mixed methods study where oral health literacy was assessed using the Health Literacy in Dentistry scale (HeLD-14) questionnaire and semi-structured interviews explored oral health related knowledge, perceptions and attitudes. Interviews were analysed using a thematic approach. RESULTS: A sample of 48 participants attending a public dental clinic in Western Sydney was recruited, with a mean age of 59.9 (SD16.2) years, 48% female, 50% born in Australia, 45% with high school or lower education, and 56% with low-medium OHL. A subgroup of 21 participants with a mean age of 68.1 (SD14.6) years, 40% female, 64% born in Australia, 56% with a high school or lower education, and 45% with low-medium OHL completed the interview. Three themes identified from the interviews included 1) attitudes and perceptions about oral health that highlighted a lack of agency and low prioritisation of oral health, 2) limited knowledge and education about the causes and consequences of poor oral health, including limited access to oral health education and finally 3) barriers and enablers to maintaining good oral health, with financial barriers being the main contributor to low OHL. CONCLUSIONS: Strategies aimed at redressing disparities in oral health status should include improving access to oral health information. The focus should be on the impact poor oral health has on general health with clear messages about prevention and treatment options in order to empower individuals to better manage their oral health.

Comparison of the Oral Health-Related Quality of Life, Sleep Quality, and Oral Health Literacy in Sleep and Awake Bruxism: Results from Family Medicine Practice.

Objectives: Bruxism is a common oral behaviour. This study aimed to compare oral health-related quality of life, sleep quality, and oral health literacy in patients with and without possible sleep bruxism (SB) and awake bruxism (AB). Materials and Methods: A cross-sectional study including 249 volunteers was conducted in a family medicine clinic of a tertiary hospital in Istanbul, Turkey. The American Sleep Medicine Association Bruxism Diagnostic Criteria, Pittsburgh Sleep Quality Index (PSQI), Oral Health-Related Quality of Life (OHRQoL) tool, Decay Missing Filled Total Teeth (DMFT) score, and Health Literacy Dental Scale-Short Form (HeLD-14) were assessed by face-to-face interviews. Data were examined using Kruskal-Wallis and Mann-Whitney U tests, Spearman correlation, and logistic regression analysis. Results: The presence of SB and AB was detected as 41.4% and 21.7%, respectively, among 91 males and 158 females, with a mean age of 36.64 ± 11.60 years. Sleep and awake bruxers had a lower oral health-related quality of life (odds ratio (OR): 0.816, 95% confidence interval (CI) = 0.770-0.864 and OR: 0.923, 95% CI = 0.956-0.982, respectively). Poor sleep quality was detected 1.28 times higher in sleep bruxism (OR: 1.277, 95% CI = 1.152-1.415) and 1.14 times higher in awake bruxism (OR: 1.141, 95% CI = 1.230-1.058). The DMFT score was found to be 1.13 times higher in SB (OR: 1.129, 95% CI = 1.043-1.223). A higher HeLD-14 score was associated with a lower DMFT score (p < 0.001; r = -0.240). The oral health literacy score was lower in AB and SB groups than in patients without bruxism, but it was not statistically significant (p = 0.267, p = 0.376). Conclusion: A lower oral health-related quality of life and poor sleep quality would be expected in the presence of SB or AB. However, patients may not be aware of it unless asked by a physician regardless of oral health literacy level.

Adults' estimated prevalence of healthy behavior in society and self-reported oral health status and behaviors.

OBJECTIVE: To assess Mashhad residents' self-perceived oral health level (OHL) and behaviors in relation to their perceptions of those of their fellow citizens. METHODS: Cross-sectional telephone survey of 384 individuals recruited from communication centers. The interviews followed a validated Persian schedule with three main sections: 1) background information, 2) questions regarding self-reported OHL, and 3) questions regarding respondents' perceptions of the OHL of their fellow citizens. RESULTS: Participants' mean self-rated OHL and tooth brushing frequency were higher than those of their fellow citizens. The correlation between self-reported and the estimated decayed and missing (DMT) was highest in the middle and lowest in the upper classes. Perceptions of the self- and others' OHL and DMT were positively correlated, with the latter being more so. Education level, age, and tooth brushing frequency affected self-perceived OHL and DMT. CONCLUSION: Participants' perceived OHL could be explained by their estimation of the general population's oral health. These findings suggest that social norm interventions could nudge improving oral health behaviors.

Oral health literacy and its associated factors among nurses: A cross-sectional study.

AIMS AND OBJECTIVES: To investigate the oral health literacy (OHL) of nurses and explore the factors affecting their OHL. BACKGROUND: OHL is important for improving the oral health outcomes. Nurses' OHL may affect the oral health of themselves, families, and patients. Few studies have examined the OHL and its related factors among nurses. DESIGN: A cross-sectional design following the STROBE guideline. METHODS: A total of 449 nurses were recruited from tertiary hospitals in the minority areas of southwest China. The participants completed an online questionnaire, which contained questions related to the OHL, sociodemographic factors, general health, oral health and related behaviours, oral health knowledge, attitudes, and oral health-related quality of life. OHL was measured using the validated Chinese version of the short-form Health Literacy of Dentistry (HeLD-14) scale. Descriptive statistics, the Mann-Whitney U test, Spearman's correlation, and multiple linear regression analysis were used to analyse the data. RESULTS: The median HeLD-14 score (p25-p75) was 50.0 (44.0-54.0). The regression model for OHL was found to be significant. The factors that influenced OHL included oral health knowledge, oral health attitudes, self-reported oral health, annual household income, and dental flossing; these factors accounted for 13.9% of the variance in OHL. CONCLUSIONS: The nurse' OHL has room for improvement. Nurses' OHL could be improved by enriching their oral health knowledge, promoting their positive oral health attitudes, increasing their household income, and helping them build correct oral health behaviours. RELEVANCE TO CLINICAL PRACTICE: The findings of the study could be used to make a case for changing nursing curricula. Oral health knowledge curriculum or programmes targeted towards nurses should be developed to improve their OHL. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution.

Online Bruxism-related information: Can people understand what they read? A Cross-Sectional Study.

BACKGROUND: Bruxism patients often access the web to search for information. Unfortunately, the low text readability of online material and the limited medical literacy in the general population may prevent patients' understanding of health information. OBJECTIVE(S): We aimed to assess the home page's readability of the top 10 patients-oriented bruxism-related websites and the educational level required to approach them. METHODS: Using the word bruxism in the "no country redirect" extension of Google Chrome browser (www.google.com/ncr), we identified the first 10 patient-oriented English language websites. The readability of the material was determined using six commonly recommended readability tests (1): Gunning Fog Index (GFI), Coleman Liau Index (CLI), Automated Readability Index (ARI) Simple Measure of Gobbledygook (SMOG), Flesch Kincald Grade Level (FKGL), Flesh Reasing Ease (FRE). RESULTS: The USA National Institutes of Health requirements, which call for websites to be readable at a 6th to 7th-grade level, were not followed by any of the most popular websites. CONCLUSION: The average consumer frequently finds the health information on the Internet to be too complex to understand, which can lead to misinterpretation, a delay in diagnosis, and poorer health consequences.

Assessment of oral health literacy and oral health-related quality of life in Saudi university students: A cross-sectional study.

BACKGROUND: Oral health literacy was recognized as important to encouraging oral health and avoiding oral health diseases. It is recognized that socioeconomic conditions are also influential factors in oral health. Therefore, oral health is an important part of individuals' quality of life and general health. OBJECTIVES: This study was conducted to assess oral health literacy (OHL) and oral health-related quality of life (OHRQoL) among undergraduate students studying at university. METHODS: A prospective cross-sectional study was carried out from November to February 2023 among the students of King Khalid University. OHL and OHRQoL were assessed using a Rapid estimate of adult literacy in dentistry-30 (REALD-30) and oral health impact profile (OHIP-14). Further, Pearson's correlation tests were used to measure the correlation between REALD-30 and OHIP-14. RESULTS: Among the 394 completed respondents, the majority were aged >20 years (n = 221; 56.09%), aged <20 years (n = 173; 43.91%), female (n = 324; 82.23%) and male (n = 70; 17.7%). Participants from health-related colleges were (n = 343; 87.06%), and other colleges were (n = 51; 12.94%) *p < .04. Participants brushing frequency once daily were (n = 165; 41.88%) twice or more per day (n = 229; 58.12%) *p < .018. The overall mean REALD-30 score of the participants was 11.76 ± 0.17 indicating low OHL. The higher mean score of OHIP-14 for the following domains physical pain 12.93 ± 0.56, physical disability 12.05 ± 0.72 and psychological disability 12.71 ± 0.76. Oral health impact profile-14 and REALD showed a positive correlation for health-related colleges (r = .314; *p < .002) and other colleges (r = .09; p < .072). However, a significant correlation was observed between REALD-30 and OHIP-14 scores among health-related colleges (p < .05). The current study concluded that self-rated poor oral health is significantly linked with OHIP-14 scores. Furthermore, systematic health education programs such as regular dental check-ups for college students must be arranged to assist in changing the student's everyday life and oral health behaviours.
