Oral health and caries/gingivitis-associated factors of adolescents aged 12-15 in Shandong province, China: a cross-sectional Oral Health Survey

Health literacy, oral diseases, and contributing pathways: results from the Lifelines Cohort Study

OBJECTIVE

Health literacy (HL), the ability to deal with information related to one's health, may affect oral health via several routes. Therefore, this study aimed to examine the association of HL with oral diseases, and whether this association is mediated by oral health behaviour and dental care utilisation.

METHODS

We included 26,983 participants from the prospective multigenerational Dutch Lifelines Cohort Study to estimate the association between limited health literacy, and self-reported oral health outcomes (edentulism and gingivitis), and mediation by oral health behaviour and dental care utilisation. Structural equation modelling was used to assess HL's direct, indirect, and total effects on oral health outcomes.

RESULTS

Limited health-literate participants had increased odds of having poor oral health outcomes, i.e. edentulism (odds ratio: 1.41; 95 %-confidence interval: 1.24 to 1.58) and gingivitis (1.22; 1.14 to 1.30). After adjustment for age, income, and education, brushing behaviour and dental care utilization showed a significant mediation effect. Brushing behaviour mediated 7.4 % of the association between HL and edentulism and 6.7 % for gingivitis. Dental visits accounted for 38.0 % of the association between HL and edentulism and 16.4 % for gingivitis.

CONCLUSIONS

Limited HL makes edentulism and gingivitis more likely, with poor oral health behaviour and inadequate dental care utilisation being important mediators. The findings suggest that interventions should focus on helping dental professionals recognize patients with limited HL and providing training in patient-centered communication to improve oral health outcomes.

CLINICAL SIGNIFICANCE

This study demonstrates that limited health literacy significantly increases the risk of edentulism and gingivitis, mediated by inadequate oral health behaviours and dental care utilization. These findings highlight the need for targeted interventions to improve HL, thereby enhancing oral health outcomes and reducing disparities in clinical dental practice.

Prevalence of Dental Fear and Its Association with Oral Health Status Among School Children in Bosnia and Herzegovina: A Cross-Sectional Study

Background and Objective: This study aimed to examine the prevalence of dental fear among schoolchildren in Bosnia and Herzegovina, analyze the distribution of dental anxiety by gender, age, and place of residence in relation to perceived sources of fear, and evaluate its association with oral health status. Materials and Methods: The sample included 355 schoolchildren between the ages of 12 and 15. Data were gathered using a self-assessment questionnaire, a brief clinical oral examination, and the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Results: Clinical examinations showed that 87.61% of the children had dental caries, with a mean DMFT score of 3.75 (SD = 2.93). The prevalence of dental caries was significantly higher in the older group compared to the younger group (p < 0.01). Dental fear was present in 21.7% of the children, with a mean total CFSS-DS score of 27.50 (SD = 13.85). The most feared aspect among the children was "Choking" (73.8%), followed by "Injections" (63.7%) and "The noise of the dentist drilling" (52.1%). Children with dental fear had a significantly greater number of decayed and missing teeth, higher DMFT scores, and poorer gingival health and oral hygiene compared to those without dental fear (p < 0.01), even after adjusting for sociodemographic factors. Conclusions: The study found a moderate level of dental fear among Bosnian schoolchildren, with younger children and those from urban areas showing more fear of injections. It also showed a consistent link between dental anxiety and clinical factors such as caries, gum disease, and oral hygiene, even after adjusting for sociodemographic factors.

Factors Influencing Adolescents' Knowledge, Practices, and Attitudes Towards Oral Health in the Rupa-Rupa District, Peru

Aim

This study aimed to identify factors associated with adolescents' knowledge, practices, and attitudes (KPA-OH) regarding oral health in the Rupa-Rupa district, a high jungle region of Peru.

Materials and Methods

An analytical study was conducted with a sample of 408 adolescents (aged 13-17 years) from seven public schools in the Rupa-Rupa district (elevation: 649 meters above sea level). The sample was stratified by sex, age, and school. Data were collected using a 49-item questionnaire, which included sections on knowledge (10 items), practices (10 items), and attitudes (13 items) toward oral health, as well as 16 sociodemographic variables. The reliability of the questionnaire was confirmed (KMO ≥ 0.537, Bartlett's test: P < 0.001, ω ≥ 0.7). Multiple linear regression models were used to analyze associations, with significance set at P < 0.05, using Jamovi software.

Results

Correct knowledge regarding oral health was highest for understanding the functions of teeth (speech, chewing), the link between caries and bacteria-sugar interaction, the relationship between gingivitis and gum inflammation, fluoride as a remineralizing agent, and the use of dental floss for cleanliness (73.3%-99.8%). Appropriate oral health practices, such as using an individual toothbrush, replacing it quarterly, and brushing twice a day for 2 minutes (89.8%-99.8%), were associated with being the only child and not having reading difficulties (P ≤ 0.03). Positive attitudes toward brushing and dental visits for caries and gingivitis prevention were more prevalent in females (P < 0.001). Multiple regression analyses revealed that demographic factors explained 21.4% of the variance in oral health knowledge (F = 2.05, P < 0.001), but had no significant predictive value for oral health practices (P = 0.127) or attitudes (P = 0.230). Significant predictors of better knowledge included being female (β = 0.3257, P = 0.026), aged 15-17 years (β = 0.6477-0.8246, P ≤ 0.006), and having part-time employed parents (β = 0.5097, P = 0.007). Negative associations with knowledge were observed in adolescents with reading difficulties (β = -0.6376, P = 0.018) and comorbidities (β = -0.5405, P = 0.031).

Conclusion

Factors such as sex, age, sibling position, general health, reading abilities, and parental employment status were found to influence adolescents' oral health knowledge, practices, and attitudes. Clinically, these findings suggest that targeted oral health education programs should consider these demographic factors, especially for adolescents with reading difficulties and comorbidities, to improve oral health outcomes in underserved populations. The results also highlight the need for interventions that emphasize preventive oral health practices, particularly among younger adolescents and those from lower socioeconomic backgrounds.

Impact of an Educational Intervention on Oral Health Knowledge and Bacterial Plaque Control in Male Secondary School Students in a Peruvian Province: A Quasi-Experimental Study

Background

The purpose of this study was to evaluate the effect of an educational intervention on oral health knowledge and bacterial plaque control in male secondary school students in a Peruvian province.

Methods

This quasi-experimental study evaluated 294 male secondary school students in southern Peru. Oral health knowledge was measured with a validated 20-item questionnaire. Bacterial plaque was measured with the Simplified Oral Hygiene Index (OHI-S). This was rated as Excellent: 0, Good: 0.1-1.2, Fair: 1.3-3.0 and Poor: 3.1-6.0, before receiving the educational intervention and after four weeks of receiving it. Variables such as age, area of residence, having health professionals as family members, educational level of mother and father, and living with parents were considered. A significance level of p<0.05 was considered.

Results

The comparison between the level of oral health knowledge and the OHI-S, before and after 4 weeks of receiving the educational intervention, showed a significant improvement (p<0.05) in all the categories of the variables studied. Likewise, before the educational intervention, there were significant differences in global knowledge about oral health among the categories of the following variables: age group (p=0.040), area of residence (p<0.001), educational level (father) (p=0.011) and living with parents (p<0.001). However, after four weeks of receiving the educational intervention, no significant differences were observed in all the variables studied (p>0.05). Regarding the OHI-S, no significant differences were observed in any of the variables studied, both before (p>0.05) and after four weeks (p>0.05) of receiving the educational intervention.

Conclusion

After four weeks, the educational intervention significantly improved oral health knowledge and significantly reduced plaque bacterial plaque in male secondary school students in a Peruvian province, regardless of age, area of residence, having health professional family members, educational level of mother and father, and living with parents.

The prevalence of gingivitis and related risk factors in schoolchildren aged 6-12 years old

BACKGROUND

According to epidemiological studies, gingivitis is a common disease. However, its morbidity, considerably varies among individual. This study aimed to investigate the epidemiological characteristics of gingivitis, including prevalence, severity, intraoral distribution, and associated risk factors, in children aged 6-12 years in Jinzhou, China.

METHODS

A multistage, whole-group, randomized sample of 2880 children aged 6-12 years in Jinzhou City, China, was selected and clinically examined. Each selected child completed a questionnaire on sociodemographic factors and oral health behaviors in cooperation with the investigator and teacher. Gingival bleeding refers to the bleeding of 10% or more teeth under the condition of ingivitis. Gingivitis was further categorized into localized gingivitis (30% ≥ number of teeth positive for gingival bleeding ≥ 10%) and generalized gingivitis (number of positive for gingival bleeding > 30%). The score of gingival bleeding was recorded using the Gingival Index.

RESULTS

The prevalence of gingivitis in children aged 6-12 years in Jinzhou was 28.58%, including 701 cases of localized gingivitis (24.3%) and 122 cases of generalized gingivitis (4.2%). There were 429 cases (28.3%) of gingivitis in males and 394 cases (28.9%) in females, with no statistically significant difference in prevalence between males and females (P > 0.05). Chi-square tests and binary logistic regression analysis showed that aging, dental calculus, plaque, and dental crowding were significantly associated with a high prevalence of gingivitis.

CONCLUSIONS

Our study showed that dental calculus, large amount dental plaque, poor oral health behavior, and oral health awareness are associated with the prevalence of gingivitis and maintaining children's oral health requires professional guidance and regular preventive care.

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.

Title Cross-Sectional Study to Evaluate Knowledge and Attitudes on Oral Hygiene of Romanian Students

Background and Objectives: the purpose of this study was to evaluate students’ level of knowledge and attitude towards oral hygiene. Materials and Methods: the evaluation was carried out by a questionnaire, with 30 Q (questions) as follows: demographic data (Q1–Q5), oral hygiene knowledge data (Q6–Q23) and oral hygiene attitude data (Q24–Q30). The study included students from Romanian schools and the selection of the study group was made following selection criteria in accordance with ethical issues. A descriptive statistical analysis was performed and a value of p ≤ 0.05 was considered statistically significant. Results: the study included a number of 718 subjects with a mean age of 14.54 (±2.22), male 250 (34.8%) and female 468 (65.2%), MS (middle school students) 354 (49.4%) and HH (high school students) 364 (50.6%). Most of the subjects 292 (MS = 160; HS = 132) know a toothbrushing technique, p = 0.009, r = 0.091 and 587 (MS = 278; HS = 309) know that brushing removes the bacterial plaque p = 0.027, r = −0.082 but only 147 (MS = 71; HS = 76) know that (by) brushing can re-mineralize hard dental structures. The duration of the toothbrushing is variable, for 2- or 3-min p = 0.058, r = 0.043. Criteria for choosing the toothbrush were based mainly on the indications of the dentist, respectively, for toothpaste on its properties. The frequency of toothbrushing is mainly twice a day 428 (MS = 234; HS = 248), p = 0.079, r = 0.037, 73 (MS = 33; HS = 40) after every meal. p = 0.099, r = 0.095. Mouthwash is used by 421 (MS = 199; HS = 222) p = 0.111, r = −0.048, and 228 (MS = 199; HS = 222) after each brushing. Dental floss is used by 240 (MS = 106; HS = 134), p = 0.031, r = −0.073 and only 74 (MS = 41; HS = 33) after each brushing. Conclusions: there are differences in the level of knowledge and attitudes regarding the determinants of oral hygiene depending on the level of education.

Is Pediatric Dentistry a Topic of Interest for Pediatric Journals? A Scoping Review

BACKGROUND

Pediatric dentistry shares many skills with pediatrics. This review evaluates the amount of literature on pediatric dentistry in the first 30 pediatric journals classified by the Web of Science in 2019. The aim was to perform a quantitative analysis of the main dental topics addressed.

METHODS

A scoping review with the PRISMA-ScR criteria was performed. The Clarivate Analytics Journal Citation Report was consulted for journals ranked in the category "Pediatrics" in 2019. Papers were searched in PubMed using an ad hoc prepared string.

RESULTS

A total of 504 papers were included. Papers on dental hard tissues were the most prevalent (45.6%), followed by dental public health (23.2%), orofacial development (15.3%), soft tissues related conditions (12.3%), and orofacial trauma (3.6%). Increasing trends have been observed for total papers published (R2 = 0.9822) and total dental papers (R2 = 0.8862), with no statistically significant differences (χ2(6) = 0.051 p > 0.05). The majority of papers (n = 292, 57.9%) were cited between 1 and 10 times, whilst less than 7% of papers received more than 40 citations.

DISCUSSION

It is desirable that papers on pediatric dentistry increase in the pediatric scenario, allowing the two related disciplines to intertwine more in the future.
