Impact of dental caries and Self-perceived oral health on daily lives of children and mothers in rural Egypt: a household survey.

BACKGROUND: The present study assessed the impact of oral health on the daily lives of children and mothers living in a rural area in Northwestern Egypt. METHODS: A cross-sectional household survey including children between 6 and 12 years old and their mothers was conducted in rural Egypt, 2019-2020. Data were collected using clinical examination and interview-based questionnaires of children and mothers. Three binary logistic regression models were used to assess the relationship between the dependent variables (oral health impact (yes, no) on avoiding smiling, chewing problems, and missing school (children) and avoiding social events (mothers)), and the explanatory variables: oral health (clinically-assessed caries experience and self-reported oral health) controlling for sociodemographic profile (child age and sex, mother's education), daily toothbrushing and village of residence. RESULTS: A total of 211 households with 355 children and 211 mothers were included (91.5% response rate). About 54% of the children were girls, mean (SD) age = 8.7 (2.05) years and 82.3% did not brush their teeth daily. Mother's mean (SD) age was 31.70 (5.45) years. Because of dental problems, 31.3% of children reported chewing difficulties, 31% avoided smiling compared to 76.3% and 43.6% of mothers. Also, 30.4% of children missed school and 76.8% of mothers reported reduced participation in social activities. In children, the number of decayed anterior teeth was associated with significantly higher odds of avoiding smiling (AOR = 1.22, 95%CI: 1.03, 1.44). In mothers, a greater number of posterior missing teeth was associated with significantly higher odds of chewing difficulties (AOR = 1.21, 95%CI: 1.01, 1.45), and a greater number of all missing teeth was associated with significantly higher odds of reduced participation in social events (AOR = 1.30, 95%CI: 1.30, 1.57). Good/ very good reported oral health in children and mothers was associated with lower odds of avoiding smiling and chewing problems (p < 0.05). CONCLUSION: Decayed anterior teeth in children have a negative impact on smiling whereas missing teeth in mothers affect the ability to chew food and socialize. The psychological, functional, and social impacts of caries in this rural setting needs to be mitigated by improving oral health literacy and access to care.

Development and acceptability of behavioral interventions promoting mothers' brushing of pre-school children's teeth: The preparation phase of the multi-phase optimization strategy framework.

BACKGROUND: Early childhood caries can be prevented through regular parental-supported toothbrushing, indicating the importance of behavior modification interventions targeting parents. Mobile oral health (m-oral health) interventions are gaining increased popularity although their production is not always based on solid theoretical frameworks and evidence about the efficacy of individual intervention components is not available. The Multiphase Optimization Strategy (MOST) offers a framework to develop complex m-oral health interventions and assessing the efficacy of individual components. AIM: This study describes the development and assesses the acceptability of 3 intervention components using MOST to promote mothers' brushing of their preschool children's teeth. METHODS: The Theory of Planned Behavior guided the development of 3 components: motivational interviewing (MI), storytelling videos (STVs), and oral health promotion messages (OHPMs). A researcher received training to conduct MI. Twenty-four OHPMs were developed, and 14 STVs scripts were developed based on the "And, But, Therefore" framework. A feasibility pilot study was conducted to determine the optimization objective and assess mothers' preferences regarding the frequency and timing of receiving the intervention components. The mothers participated in a semi-structured interview to assess the acceptability of the components using 7 open-ended questions based on the framework of acceptability and thematic analysis was used to analyze the qualitative data. The mothers also responded to questions assessing the perceived and experienced acceptability of the components using close-ended questions. Descriptive statistics were presented as means and standard deviations for continuous variables and median and interquartile range for categorical variables. RESULTS: Sixteen mothers were included. The mothers expressed positive affective attitude towards the interventions. They felt the components served as "good reminders" to brush their children's teeth. However, "time" was a burden for the mothers. 80% of the mothers preferred receiving the OHPMs and STVs once per week, from 8 pm to 2 am (50%), and 60% indicated they can set 15-30 min to receiving the interventions. CONCLUSION: The 3 components were acceptable to the mothers. The OHPMs and STVs will be sent to the mothers once per week, between 8 pm to 2 am. The MI and follow-up phone calls will be limited to 15 min.

Using mHealth to promote parents' brushing of preschool children's teeth: a protocol for a randomized factorial trial using the Multi-phase Optimization Strategy (MOST).

BACKGROUND: Early childhood caries is a highly prevalent disease affecting young children. Parental brushing of children's teeth is recommended during preschool years. Interventions to promote parental brushing of children's teeth are assessed as a package in randomized clinical trials and the efficacy of separate components is not known. METHODS AND ANALYSIS: The aim of this study is to develop an optimized behavior modification intervention to increase parents' brushing of their pre-school children's teeth using the multi-phase optimization strategy (MOST) guided by the Theory of Planned Behavior. Behavior change will be assessed by the percent reduction in children's dental plaque index after 6 months and parents reporting of toothbrushing frequency. Two phases of MOST will be carried out. First, the preparation phase comprises the development of a conceptual framework, identifying candidate components, conducting a feasibility pilot study to assess the acceptability and the design features of three intervention components (motivational interviewing (MI), and two mobile health (mHealth) components: oral health promotion messages and storytelling videos delivered using WhatsApp messenger) in addition to setting an optimization objective. Second, the optimization phase constitutes a factorial trial assessing the three intervention components and developing the intervention by selecting the most effective components within the optimization constraint. Each component will be set at two levels: yes (the intervention is applied) and no (the intervention is not applied). A linear regression model will be used to assess the effect of the intervention components on the percent reduction in dental plaque index (primary outcome measure). The secondary outcome measure is the change in the frequency of parents' brushing of the child's teeth. The combination of components making up the new optimized intervention will be selected. DISCUSSION: This will be the first study to apply the MOST framework in the field of dentistry. The results of this study can guide the development of an optimized behavior modification interventions using mHealth and MI.

Dental practice closure during the first wave of COVID-19 and associated professional, practice and structural determinants: a multi-country survey.

BACKGROUND: The coronavirus outbreak (COVID-19) in China has influenced every aspect of life worldwide. Given the unique characteristics of the dental setting, the risk of cross-infection between dental practitioners and patients is high in the absence of adequate protective measures, and dentists may develop severe anxiety in relation to the current pandemic. The limited provision of services and widespread closure of dental practices have raised concerns among dental professionals about the financial impact. The present study assessed the frequency of dental practice closure during the pandemic's first wave in several countries and whether closures and their associated factors differ between the private and non-private sectors. METHODS: An electronic cross-sectional survey questionnaire was sent to dentists in several countries, from April to May 2020. The survey assessed professional, practice related and country-level structural factors elucidating the reason for practice closure. Multilevel logistic regression was used to assess the association between practice closure and these factors, and differences were evaluated by sector type. RESULTS: Dentists from 29 countries (n = 3243) participated in this study. Most of the participants (75.9%) reported practice closure with significantly higher percentage in the private sector than the non-private sector. Greater pandemic-related fears were associated with a significantly higher likelihood of practice closure in the private (odds ratio [OR] = 1.54, 95% confidence interval [CI] 1.24, 1.92) and non-private (OR = 1.38, 95% CI 1.04, 1.82) sectors. Dentists in non-private rural areas (OR = 0.58, 95% CI 0.42, 0.81), and those in hospitals (overall OR = 0.60, 95% CI 0.36, 0.99) reported a low likelihood of closure. A high likelihood of closure was reported by dentists in the academia (OR = 2.13, 95% CI 1.23, 3.71). More hospital beds at the country-level were associated with a lower likelihood of closure in the non-private sector (OR = 0.65, 95% CI 0.46, 0.91). Private- sector dentists in high- income countries (HICs) reported fewer closures than those in non-HICs (OR = 0.55, 95% CI 0.15, 1.93). CONCLUSIONS: Most dentists reported practice closure because of COVID-19, and greater impacts were reported in the private sector than in the non-private sector. Closure was associated with professional, practice, and country-levels factors.
