Structural equation model for parental influence on children's oral health practice and status

Parental knowledge, attitudes, and practices regarding malocclusion in preschool children

This cross-sectional study aimed to assess the knowledge, attitudes, and practices (KAP) of parents regarding malocclusion in preschool-aged children in Nanchong City, Sichuan Province, between January and July 2024. Data were collected via questionnaires to gather demographic information and assess parents' KAP, with univariable and multivariable logistic regression analyses used to explore the associations between demographic factors and KAP. Structural equation modeling (SEM) was applied to investigate complex relationships among relevant factors. A total of 2811 valid cases were included, of which 61.2% were female. The mean scores for knowledge, attitude, and practice were 3.71, 26.50, and 40.98, respectively. Positive correlations were found between knowledge and attitude (r = 0.491), knowledge and practice (r = 0.275), and attitude and practice (r = 0.336). SEM revealed that knowledge had a direct effect on both attitude (β = 0.509) and practice (β = 0.204), while attitude also directly influenced practice (β = 0.176). Knowledge indirectly impacted practice through attitude (β = 0.090). Parents showed inadequate knowledge and generally negative attitudes but positive practices. Educational interventions are recommended to improve parental knowledge and attitudes, which may lead to better malocclusion management practices.

Pathways Between Parental Attitudes and Early Childhood Caries in Preschool Children

Background/Objectives: Parental attitudes play a crucial role in shaping children's oral health habits and preventing dental diseases. This study aimed to explore the theoretical pathways through which parental behavior and attitudes toward child oral health can influence the dental caries experience as measured by the dmf-t index in preschool children in Lithuania. Methods: A cross-sectional study was conducted involving 302 children aged 4-7 years and their parents (262 mothers). Parental attitudes were assessed using the Parental Attitudes Towards Child Oral Health (PACOH) scale. For the children, the following variables were considered: sex, age, dental caries experience (dmf-t index in the primary dentition), oral hygiene index (Silness-Löe Plaque Index), toothbrushing frequency, and parental assistance with toothbrushing. Structural Equation Modeling (SEM) was applied for the data analysis. Results: The main path through which parental attitudes towards child oral health influenced the dmf-t index was via toothbrushing frequency (β = -0.17) or parental assistance with toothbrushing (β = 0.24). These factors were then linked to the oral hygiene index (β = 0.20 and β = -0.47, respectively), which ultimately influenced dmf-t (β = 0.52). The parents' attitudes and toothbrushing frequency per se had no significant effect on children's dmf-t (β = -0.06 and β = -0.04, respectively). The final model met all goodness-of-fit criteria: Chi-square test p = 0.211, Incremental Fit Index IFI = 0.994, Tucker-Lewis Index TLI = 0.982, Comparative Fit Index CFI = 0.994, and Root Mean Square Error of Approximation RMSEA = 0.038. Conclusions: Findings from this study demonstrate that parents play a significant role in determining children's oral health. Regular toothbrushing, parental assistance with toothbrushing, and good oral hygiene are critical factors linking parents' oral health-related attitudes to a child's experience of early caries. Identifying the associations between dental caries risk factors helps plan interventions.

Mothers' Knowledge, Attitude, and Behavior Concerning Their Kindergarten Children's Oral Health: A Cross-Sectional Study

OBJECTIVES

To evaluate the level of oral health-related knowledge, attitudes, and behavior among a group of mothers with kindergarten (KG) children aged 3-5 years toward their own and their children's oral health and assess its influence on their children's oral health status.

MATERIAL AND METHODS

This was a cross-sectional study conducted in Jeddah, Saudi Arabia. The sample was selected randomly from public and private KGs in Jeddah. Self-administrated questionnaires were distributed to the mothers of KG schoolchildren aged 3-5 years, which contained translated and validated Mothers' Behavior Questionnaire about their own oral health behaviors, Mothers' Attitude Questionnaire about their children's oral health, and Mothers' Knowledge Questionnaire about their children's oral health. The oral health of the KG school children was examined to determine the decayed, missed, and filled index (dmft).

RESULTS

A total of 461 child-mother pairs completed the study. The mean values of dmft were 5.41 ± 4.81. The children's oral health (dental caries) and the mothers' oral health-related knowledge, attitudes, and behavior were significantly associated with KG type (public vs. private), mothers' age, mothers' education, and family income. A multiple linear regression model indicated that younger mothers (< 30-40 years), highly educated mothers, high family income, and mothers with higher knowledge scores were significantly associated with lower dmft scores.

CONCLUSIONS

Mothers whose children attended private KGs exhibited better oral health-related attitudes, habits, and knowledge. School type, mother's age, mother's education level, and monthly income were factors that strongly impacted the behaviors, attitudes, and knowledge of the mothers. Dental caries was lower among children whose mothers were young, well-educated, from high family income families, and had higher knowledge related to oral health. Implementing targeted educational programs for mothers, particularly those with lower educational attainment and from low-income backgrounds, is essential for enhancing the oral health of children in kindergarten age.

Parental health belief model constructs associated with oral health behaviors, dental caries, and quality of life among preschool children in China: a cross-sectional study

BACKGROUND

Early childhood caries (ECC) is a prevalent health problem that negatively affects both overall health and oral health-related quality of life (OHRQoL). This study investigated the association between health belief model (HBM) constructs and oral health behaviors, dental caries, and OHRQoL in preschool children in China.

METHODS

A total of 1562 preschool children aged 3 to 6 years were recruited from six public kindergartens in Hangzhou, Zhejiang Province, by using stratified cluster sampling. A questionnaire was administered to parents to collect information on demographics, HBM constructs, oral health behaviors, dental caries, and OHRQoL. Regression models were used to examine relationships between HBM constructs and the outcomes.

RESULTS

Parental perceived benefits [adjusted odds ratio (AOR) = 1.47 and 1.42], perceived barriers (AOR = 0.65 and 0.63), and oral health self-efficacy (AOR = 20.59 and 19.09) were associated with brushing teeth twice daily and brushing teeth with parental assistance. Perceived susceptibility (AOR = 6.62) and perceived severity (AOR = 0.49) were significantly associated with children's ECC. Poorer oral health (β = 0.09), higher perceived susceptibility (β = 0.11), and greater perceived barriers (β = 0.30) were associated with lower OHRQoL. Brushing teeth twice daily (β = -0.19) and brushing teeth with parental assistance (β = -0.09) were associated with higher OHRQoL.

CONCLUSIONS

Parental HBM constructs were significantly associated with oral health behaviors, ECC, and OHRQoL in preschool children. These findings indicate the importance of incorporating parental HBM constructs into health education programs to promote positive oral health behaviors, reduce the prevalence of caries, and enhance OHRQoL in preschoolers.

Structure equation modeling in oral health research: A review of applications and considerations

This review provides an overview of structure equation modeling (SEM) and its applications in dental research. SEM is a statistical technique that allows researchers to examine the relationships between variables and is useful for analyzing data from a wide range of research designs, including cross-sectional, longitudinal, and experimental studies. The process involves specifying a theoretical model, testing the model with data, and evaluating the model fit. It has been used in dental research to investigate a wide range of topics, including dental diseases, oral health-related quality of life, and dental anxiety. SEM is particularly useful in modeling the relationships between various risk factors and dental diseases and also has the potential to provide a deeper understanding of the multifactorial nature of dental diseases such as periodontitis, dental caries, and oral cancer. Moreover, the insights provided can aid in the development of effective strategies for the prevention and treatment of dental diseases. It is a powerful statistical tool that can be used by dental researchers to gain a better understanding of the intricate interplay of factors that underlie dental diseases and other oral health-related outcomes.

Effectiveness of theory-based educational interventions of promoting oral health among elementary school students

BACKGROUND

The aim of the present study was to determine the effect of oral health education programs on the oral health of primary school students.

METHODS

In this randomized controlled trial study, 190 elementary fifth-grade female students were chosen using the multistage cluster sampling method. In this study, the Plaque Index (PI), Simplified Oral Hygiene Index (OHI-S), Community Periodontal Index (CPI), tooth brushing using fluoride toothpaste, dental flossing frequency and factors affecting them were determined according to social cognitive theory (SCT). Interventions were implemented using the play method and with the help of three pamphlets, five posters, a celebration of oral health, and the creation of a Telegram group. Data were analyzed using descriptive statistics indexes, t tests, paired sample t tests, chi-square tests, and Pearson correlation tests.

RESULTS

The results showed that 3 months after the intervention, compared to before the intervention, the percentage of participants in the intervention group who brushed their teeth twice or more per day increased by 48.5%, and the percentage of participants who used dental floss at least once per day increased by 64.2%. The rate of gum bleeding decreased by 6.3%. The good OHI-S rate increased by 44.4%. Dental plaque decreased by 38.1%.

CONCLUSION

The results demonstrated that a gamification design can be effective and useful in promoting the oral health of students.

A proposal for an oral health educational programme for the first 1000 days of life: from pregnancy to childhood

AIM

The aim of this paper is to highlight the need to consider oral health during the first 1000 days of a child's life with a view to developing appropriate educational programmes.

CONTEXT

The first 1000 days of life represent a window of opportunity for prevention in children. This concept is built on a consideration of the overall health of mother and child, taking into account social inequalities in health. It is now established that the oral health of the mother determines the oral health of her child. Furthermore, parents' knowledge and behaviour have a direct influence on their child's health.

CONCLUSION

The majority of the population does not have the necessary skills to adopt behaviours that promote oral health. The need for oral health education begins in the first 1000 days of life. Following the model of family health education, these programmes would involve providing pregnant women and, therefore, families with the skills they need to manage their own oral health and that of their future child as early as possible.

Psychosocial associated factors of early childhood caries and oral health-related quality of life: structural equation model approach

OBJECTIVE

To identify a structural model for the identification of psychosocial associated factors of early childhood caries (ECC) and oral health-related quality of life (OHRQoL) in preschool children and their families.

METHODS

A population-based cross-sectional study was conducted with 533 preschool children from 4 to 6 years-old public and private preschools, from XXX, XXX. Parents/caregivers self-completed the Brazilian versions of the Early Childhood Oral Health Impact Scale (B-ECOHIS) and Resilience Scale as well as a structured questionnaire addressing socioeconomic status and child's oral health behavior. Two dentists who had undergone training and calibration exercises for ICDAS-epi and pufa index (Kappa≥0.95) performed the examinations for ECC. Stages of ECC were classified as free of visible carious lesion, initial caries, moderate caries, extensive caries without pulp consequences and extensive caries with pulp consequences. Data were analyzed using structural equation modeling, using Mplus version 8.6.

RESULTS

Lower socioeconomic status (b=-0.250; p<0.001) and higher frequency of free sugar consumption (b=0.122; p=0.033) were directly associated with a more severe stage of ECC. Lower parental resilience had an indirect impact on more severe stage of ECC which was mediated by the variable 'frequency of free sugar consumption' (b=-0.089; p=0.048). ECC was associated with lower child's OHRQoL (b=0.587; p<0.001) and lower family's OHRQoL (b=0.506; p<0.001).

CONCLUSION

Structural modeling revealed that the severity of ECC negatively impacted the OHRQoL of preschoolers and their families. The main associated factors of the severity of ECC were lower socioeconomic status, higher frequency of free sugar consumption and lower parental resilience.

CLINICAL SIGNIFICANCE

T The findings indicate that psychosocial and behavior variables can be associated with the severity of ECC, and ECC can be associated with negative impact on wellbeing and ability to perform daily activities of preschoolers and their families.

Oral hygiene practices in nurseries (0-3 years) in the cities of Pavia and Vigevano

Aim

This study was conducted to evaluate attention to and knowledge of oral care in children aged 0-3 years, on the basis of data collected from early years educators working with this age group. Information was also collected about the oral hygiene practices adopted in nurseries and the types of food provided, with the aim of increasing knowledge and raising awareness of this topic.

Materials and methods

A questionnaire was created using the "Google Forms" program and sent to all the 47 nurseries in the city of Pavia and Vigevano.

Results

Twenty establishments agreed to take part in the research. Assessment of knowledge and of awareness of oral care among early years educators caring for children in the age range 0-3 years revealed variability and some confusion. The results showed a general lack of attention to oral care in the period before the milk teeth appear, as well as limited use of gauze swabs. There was generally some use of educational play focusing on this issue, albeit not daily across all the nurseries participating in the survey. Nurseries rarely had the support of a professional dental hygienist to raise awareness among early years educators and parents.

Conclusions

The findings obtained through this study indicate that, in the area surveyed, there is a lack of widespread knowledge and awareness of oral prevention in young children, and of the oral hygiene maintenance techniques to use in this age group. This suggests a need to develop preventive protocols to improve knowledge and awareness of children's oral health among the adults who care for them.

Knowledge of Breastfeeding Mothers Regarding Caries Prevention in Toddlers

Mothers' awareness regarding the risk factors for the development of early childhood caries is crucial. The current study aims to examine the knowledge of breastfeeding mothers about their baby's dental health and prevention of ECC while comparing primiparous mothers to multiparous mothers. A total of 165 mothers aged 20-49 y/o participated in the study by completing questionnaires that assessed the knowledge and attitudes of mothers toward their infants' oral health. Results showed that (1) mothers were found to be highly knowledgeable regarding the oral hygiene of their infants and the recommended breastfeeding best practices (71%); (2) mothers with lower education showed poor knowledge regarding the recommended practices of infant oral health; (3) a large proportion of the mothers in the sample (62%) reported that they usually tasted the food before giving it to their baby, in a way they could transmit bacteria to infants; (4) most of the mothers (68%) were not aware that their dental health during pregnancy affects the infants' dental health; and (5) multiparous mothers were more knowledgeable regarding artificial baby milk composition (96%) in comparison with mothers with only a single child (60%). According to the results, there is a need to improve the knowledge of breastfeeding mothers, especially mothers who have one child and mothers with a lower education about their baby's dental health. The results of this study shed light on the knowledge of breastfeeding mothers on this important topic and could serve policymakers to improve practices toward advancing better oral health for infants, without sacrificing the benefits of breastfeeding, which are so crucial for infant health and development.

Effectiveness of an integrated model of oral health-promoting schools in improving children's knowledge and the KAP of their parents, Iran

INTRODUCTION

The aim of our study was to investigate the effect of an Oral Health Promoting School (OHPS) model on children's oral health in Iran.

METHODS

This interventional quasi-experimental study was conducted in the academic year 2019-20 among 354 primary school students and their parents. A questionnaire including 17 questions was distributed among children before and 5 months after the program (The ranges of possible scores = 0-17). Training workshops for the parents based on the theoretical domains framework were designed. Using educational sessions, pamphlets, tooth brushing dairies, assignments to do at home, educational videos and messages as reminders in social networks, parents were educated about dental caries, its risk factors and prevention principles. Best recommended oral health behaviors including tooth brushing and the use of fluoridated tooth paste were also educated. A questionnaire consisting of 18 knowledge (The ranges of possible scores = 0-18), 13 attitude and 10 practice questions were distributed among parents before and after the workshops. The data were fed into SPSS and analyzed by descriptive and analytic statistics such as T-test, ANOVA and Correlation Coefficients (α = 0.05).

RESULTS

The mean pre-test knowledge (7.8 ± 1.7) was increased significantly in three schools after program, p < 0.001. In the post-test, girls gained significantly higher scores (9.61 ± 1.98 vs. 9.06 ± 1.4, p = 0.025). Among 147 parents, the mean knowledge was raised from 12.3 ± 3.1 (5-18) to 15 ± 3.03 (6-18), p < 0.001. Knowledge score of the parents attending both sessions was higher. Practice of the parents regarding the use of fluoridated tooth-paste was significantly improved (p < 0.001). Also, their attitude toward the ability of children to take care of their teeth was improved (p = 0.029). Based on the self-report of parents, 71.4% (n = 47) of mothers and 45.6% (n = 67) of their children used to brush once or two times daily and there was a correlation between their behaviors (p < 0.001, Spearman Correlation Coefficient = 0.4).

CONCLUSION

It seems that the education provided in OHPS had positive effects on increasing students' awareness and to some extent, the knowledge, attitude and practice of the parents.

Effects of Parental Migration on Dental Caries of Six- to Eight-Year-Old Children Using Structural Equation Modeling

This cross-sectional study aimed to document the relationship between dental caries, oral health behaviors, and the duration of parental migration in rural Yunnan, China, from September to December 2020. Seven rural primary schools with high parental migration were studied. The oral health status of 500 six- to eight-year-old students was assessed using clinical examination and caregivers' interviews. A total of 51.8% of the children had at least one parent absent for at least 6 months (left-behind children). Among those children with parental migration <6 months, 40.0% consumed sugar twice or more daily and 82.8% of those with parental migration from 6 to 12 months brushed once a day or less. The percentage of daily sugar consumption twice or more and brushing once or less among those without parental migration were 36.0% and 68.6%. Prevalence of caries in permanent teeth (DMFT) in children without parental migration and those whose parental migration <6 months, 6 to <12 months, and ≤12 months were 30.9%, 20.0%, 28.7% and 19.8%, respectively. Out of several other causal pathways between parental migration and dental caries, our structural equation model delineated that sugar consumption is the important mediator variable. Special education programs may be needed to educate caregivers on sugar consumption for the left-behind children in rural areas.

What Do Mothers (or Caregivers) Know about Their Children’s Oral Hygiene? An Update of the Current Evidence

Tooth decay remains one of the most common diseases in children, although it is a preventable injury and despite significant advances that has been made in terms of attention and care for oral hygiene. Several studies have shown the association between prevalence of tooth decay in children and parents’ incorrect oral care habits, with a low educational level and a low socioeconomic background. The question that arises concerns the actual oral hygiene knowledge of mothers, fathers, family members or caregivers of young patients; therefore, the aim of this review is to investigate the genesis of gaps in the topic. A literature search was conducted through the Scopus and PubMed search engine and ended in May 2022; only studies from the past 20 years were included. Current evidence suggests that parents and caregivers still have little knowledge about their children’s oral health: there is not enough awareness about the importance of preventing oral diseases, due to poor attention to good oral hygiene but also lack of information from health professionals and institutions. In the future, all the professionals involved in the pregnant woman’s care should increase parents’ knowledge, solve their doubts, collect and compare data in order to design effective intervention programs.

Can mHealth promotion for parents help to improve their children's oral health? A systematic review

OBJECTIVE

This systematic review evaluated the effectiveness of oral health education using mHealth approach to parents for improving their children's oral health.

DATA

Twelve studies were included after the screening and five studies in the data synthesis. The sample size varied from 34 to 1055. There was a very low level of evidence showing that mHealth approach could increase parents' knowledge and improve their brushing behaviors for children when compared to a negative control group. There was a low level of evidence showing mHealth approach could be more effective than printed material in increasing the parents' oral health knowledge.

SOURCES

This systematic review was registered on PROSPERO (#CRD42021289324) with no funding support.

STUDY SELECTION

Studies targeting parents/caregivers of children age 12 or under were included. Interventions should be oral health promotion delivered via mobile devices. Study outcomes were parents' oral health knowledge, attitude and behaviors, and children's oral health status. Eight electronic databases/registration platforms: PubMed, Cochrane Library, Embase, WoS, Global Health, Engineering Village 2, WHO ICTRP and ClinicalTrials.gov were lastly searched on 6th Oct 2021. The risk of bias tools used were RoB 2.0, ROBINS-I and NIH quality assessment tool for pre-post study. Meta-analysis using a fixed-effect model or vote counting based on the direction of effect was performed.

CONCLUSION

All included studies had a high risk of bias. Low/very low certainty of evidence existed that the mHealth approach could improve parents' oral health knowledge. However, there lacks evidence to show the effects of mHealth intervention exerted on other outcomes.

CLINICAL SIGNIFICANCE

The mHealth intervention could be a good approach to improve the parent's oral health knowledge. However, the theoretical model must be considered when designing the educational content. More research should be conducted to test the effectiveness of mHealth approaches on children's oral health status.

Association between socioeconomic status and dental caries among Chinese preschool children: a cross-sectional national study

OBJECTIVES

Socioeconomic inequalities in oral health are often neglected in oral health promotion. This cross-sectional study assessed the association between dental caries and socioeconomic status (SES) among preschool children in China.

DESIGN

Cross-sectional study.

SETTING

Data from the Fourth National Oral Health Survey of China (2015), comprising of 40 360 children aged 3-5 years was used.

METHODS

Dental caries indicators including prevalence of dental caries, dental pain experience and number of decayed, missing and filling teeth (dmft). SES indicators included parental education and household income. The associations between SES and dental caries were analysed by using negative binomial regression or Poisson regression models according to data distribution. Relative and absolute inequalities in dental caries were quantified by using the Relative Index of Inequality (RII) and Slope Index of Inequality (SII), respectively.

RESULTS

There were significant associations between SES and prevalence of dental caries and dmft (p<0.001). Children from lower educated (RII 1.36, 95% CI 1.3 to 1.43; SII 0.97, 95% CI 0.81 to 1.13) and lower household income (RII 1.17, 95% CI 1.11 to 1.24; SII 0.55, 95% CI 0.35 to 0.75) families had higher dmft than those from well-educated and most affluent families. Relative and absolute inequalities in dental caries were larger in urban areas by household income, and in rural areas by parental education.

CONCLUSIONS

Association between dental caries and SES was demonstrated and socioeconomic inequalities in dental caries existed among Chinese preschool children.

Family as a health promotion setting: A scoping review of conceptual models of the health-promoting family

BACKGROUND

The family is a key setting for health promotion. Contemporary health promoting family models can establish scaffolds for shaping health behaviors and can be useful tools for education and health promotion.

OBJECTIVES

The objective of this scoping review is to provide details as to how conceptual and theoretical models of the health promoting potential of the family are being used in health promotion contexts.

DESIGN

Guided by PRISMA ScR guidelines, we used a three-step search strategy to find relevant papers. This included key-word searching electronic databases (Medline, PSycINFO, Embase, and CINAHL), searching the reference lists of included studies, and intentionally searching for grey literature (in textbooks, dissertations, thesis manuscripts and reports.).

RESULTS

After applying inclusion and exclusion criteria, the overall search generated 113 included manuscripts/chapters with 118 unique models. Through our analysis of these models, three main themes were apparent: 1) ecological factors are central components to most models or conceptual frameworks; 2) models were attentive to cultural and other diversities, allowing room for a wide range of differences across family types, and for different and ever-expanding social norms and roles; and 3) the role of the child as a passive recipient of their health journey rather than as an active agent in promoting their own family health was highlighted as an important gap in many of the identified models.

CONCLUSIONS

This review contributes a synthesis of contemporary literature in this area and supports the priority of ecological frameworks and diversity of family contexts. It encourages researchers, practitioners and family stakeholders to recognize the value of the child as an active agent in shaping the health promoting potential of their family context.

Association between procrastination in childhood and the number of remaining teeth in Japanese older adults

BACKGROUND

Procrastination is associated with stress and unhealthy behaviors. The oral condition reflects the long-term history of an individual's stress exposure and oral health behaviors; however, empirical studies on the association of procrastination in childhood with remaining teeth in older age are limited. We investigated the association of procrastination in childhood with the number of remaining teeth among community-dwelling older Japanese adults.

METHODS

In total, 1616 community-dwelling senior residents of Wakuya City (Miyagi Prefecture, Japan) who were enrolled in the National Health Plan & the Medical Care System for the Elderly completed a self-administered questionnaire on the number of teeth. Procrastination was measured using a single binary question about timing of holiday homework completion in childhood. The number of remaining teeth was assessed via a questionnaire with response options of ≥20, 10-19, 1-9, and 0 teeth. Ordered logistic regression models with potential confounders (sex, age, maternal education, childhood socioeconomic status (SES), childhood maltreatment, conscientiousness trait) and mediators (adulthood SES, smoking history, alcohol use history) were estimated.

RESULTS

Forty-six percent of participants reported a higher tendency to procrastinate in childhood. The proportions of participants with ≥20, 10-19, 1-9, and 0 teeth were 39.6, 22.7, 24.0, and 13.7%, respectively. After adjusting for all covariates, a higher tendency to procrastinate in childhood was significantly associated with having fewer remaining teeth (odds ratio = 1.28; 95% confidence interval = 1.05-1.57).

CONCLUSION

A higher tendency to procrastinate in childhood was associated with having fewer remaining teeth in later life.

Effectiveness of a family-centered behavioral and educational counselling approach to improve periodontal health of pregnant women: a randomized controlled trial

BACKGROUND

Poor oral hygiene and high hormone levels during pregnancy can lead to a deterioration in periodontal health. This study assessed the effectiveness of a family-centered behavioral and educational counselling program on improving the periodontal health of women during pregnancy and postpartum.

METHODS

A randomized controlled trial was conducted among pregnant women (10th-22nd gestational week) and their husbands. Participating families were randomized into test and control groups. Intervention in the test group included explanation of oral health education (OHE) pamphlets, oral hygiene instruction, individualized feedback, and proposed solutions to overcome barriers in self-care. Reinforcements were implemented in the 3rd trimester of pregnancy and six months postpartum. In the control group, only OHE pamphlets were distributed. The assessed outcomes were bleeding on probing (BOP), periodontal pocket (Poc), loss of clinical attachment (LoA), and Visible Plaque Index (VPI). The data collection was carried out at baseline (T₀), in the 32nd gestational week (T₁), and 12 months postpartum (T₂).

RESULTS

Altogether 589 pregnant women were recruited, and 369 attended all three visits (test:188; control:181). In the test group, the mean VPI score at T₀ was 0.19, which decreased to 0.14 at T₁ and 0.15 at T₂. In the control group, the mean VPI decreased from 0.19 at T₀ to 0.16 at T₁, but increased to 0.22 at T₂. A main effect of time and intervention and an interaction between time and intervention were detected (all p < 0.05), indicating that the intervention effect differed between T₁ and T₂. The test group showed a significantly greater decrease over time than the control group did. Similarly, the mean BOP% decreased more significantly over time in the test group (T₀:57%, T₁:46%, T₂:35%) than in the control group (T₀:58%, T₁:52%, T₂:46%). For Poc and LoA, there were improvements in both study groups at 12 months postpartum, compared with during pregnancy (p < 0.001).

CONCLUSIONS

Providing family-centered, behavioral, and educational counselling to pregnant women at an early stage of pregnancy and with reinforcements can improve their oral hygiene and reduce gingival inflammation. The effect can be sustained over an extended period and is greater than that of distributing oral health leaflets alone.

Perception of Dental Caries and Parental Difficulties in Implementing Oral Hygiene for Children Aged Less Than 6 Years: A Qualitative Study

BACKGROUND

Despite extensive prevention programs, dental hygiene remains inadequate, particularly among children under the age of six, and early childhood caries (ECC) are still a concern. Oral hygiene behavior and preventive practices seem difficult to change at a family level.

AIM

The present study aimed to better understand the reasons behind this behavior and to identify the different barriers to the implementation of adequate preventive measures.

METHODS

A qualitative study was conducted in the pediatric dentistry service of the Montpellier University Hospital (France) in 2019. A thematic analysis concerning three domains was performed: family environment, dental literacy, and oral hygiene.

RESULTS

The main barriers encountered by the parents were, respectively, (1) a weakness in the organization of familial life, together with a low-medium family income and a lack of authority, (2) ignorance of the necessity of treating carious primary teeth, and (3) a lack of time for brushing or supervising their children's teeth.

CONCLUSION

These results showed that oral hygiene and primary teeth care could not be easily achieved in the family environment of the participants, and oral health strategies should be focused not only on children but also on their parents.
