Poor parenting behaviours and dental caries experience in 6- To 7-year-old children

Dental caries prevalence in children during temporary protective care according to type of abuse

BACKGROUND

This study investigated the correlation between the prevalence of dental caries and the presence and type of abuse.

METHODS

Participants were 534 children admitted for care at two child guidance centers (CGCs) in Niigata, Japan. Data pertaining to abuse, including the reason for temporary protective care and the type of abuse, and the oral examination results of the children, were collected. These results were then compared with those of a national survey and analyzed in relation to the presence and type of abuse.

RESULTS

The odds ratio for decayed teeth was 4.1, indicating a higher risk in children admitted to the CGCs. However, no significant association was found between the presence of decayed, filled, or caries-experienced teeth and the presence of abuse. A significant positive association was observed between dental caries and one type of abuse, indicating a greater prevalence of dental caries in cases of neglect. The findings of this study suggest that the type of abuse, rather than its presence, is associated with dental caries.

CONCLUSIONS

Our findings suggest that proactive support should be provided to children in problematic nurturing environments, regardless of whether they have been subjected to abuse.

Dental radiographic changes in individuals with COVID-19: a controlled retrospective study

OBJECTIVE

The aim of this study is to compare the pre-COVID-19 and post-COVID-19 dental radiological findings of individuals with positive rRT-PCR test results and with healthy controls using the apical periodontitis grade scale (APGS), radiographic-based periodontal bone loss (R-PBL), and radiographic DMFT indices, and to investigate the relatively long-term dental effects of COVID-19.

METHODS

This study included people who had two panoramic radiographs taken between 2018 and 2022. There are 52 patients with positive rRT-PCR tests in the study group. The control group included 50 individuals. Study and control groups were compared using the apical periodontitis grade scale (APGS), radiographic-based periodontal bone loss (R-PBL), and radiographic DMFT indices.

RESULTS

Although results showed a significant difference in percentage R-PBL value and R-PBL types in the study group, there was no significant difference in percentage R-PBL value and R-PBL types in the control group. Also, both groups showed a significant difference in the DMFT index.

CONCLUSIONS

According to the results of this study, it can be said that COVID-19 increases the incidence of periodontitis, and it can be interpreted that the pandemic may adversely affect the general oral health of all people.

Is Parental Rating of Child's Oral Health Associated with Caries Experience in Children? A Cross-Sectional Study

Aim

The Parents' view to the oral health of their children is a significant factor that can impact oral health practices and behaviors. The aim of this research was to investigate how parental assessment of their child's oral health associates with caries experience in children receiving dental treatment at the hospital of Taibah University Dental College.

Materials and Methods

This cross-sectional study enrolled 127 children who underwent dental treatment at Taibah University Dental College and Hospital during 2020-2021. Dental caries experience was assessed using the dmft/DMFT index, and parental rating of oral health was obtained through a questionnaire. Three logistic regression models were used to assess the correlation between dental caries experience and parental rating of oral health while controlling for sociodemographic and behavioral factors.

Results

Most parents rated the oral health of their child as good (60.4%), followed by excellent (18.8%) and very good (15.6%). The mean dmft/DMFT score was 3.47 ± 3.46, with 43.8% of children having high/very high dental caries experience. Logistic regression analysis showed that children whose parents rated their oral health as poor were more likely to have high/very high dental caries experience compared to those rated as excellent/very good/good/fair (adjusted odds ratio = 4.45, 95% confidence interval 1.23-16.07).

Conclusion

This study suggests a link between parental assessment of their child's oral health and an elevated prevalence of dental caries in children. The study found that children whose parents rated their oral health as suboptimal had higher odds of having high dental caries experience. These findings emphasize the significance of parental perception of their child's oral health and suggest a necessity for customized interventions to enhance parental knowledge and practices concerning children's oral health.

Association between the number of convenience stores and caries status in permanent teeth among elementary school children: results from the A-CHILD population-based longitudinal cohort study

Background

In Japan, people have rich access to 24-h convenience stores where they can buy sweets, juice and fluoride hygiene products, among others. However, the association between the number of convenience stores in a neighbourhood and caries in elementary school children status has not been studied. This study aimed to investigate this particular association.

Methods

Data were derived from a population-based longitudinal cohort study (A-CHILD study) of elementary school children from first-grade to fourth-grade in Adachi City, Tokyo. Caregivers were asked to complete a questionnaire in 2015, 2016, and 2018. A total of 3,136 caregivers provided a valid response. We analysed the association using multilevel Poisson regression.

Results

The mean number of caries among children in school districts with low, middle, and high number of convenience stores was 0.31 (SD: 0.81), 0.21 (SD: 0.69), and 0.16 (SD: 0.58). After covariate adjustment, children in the school districts with high and middle number of convenience stores had 44% (mean ratio 0.56, 95% CI: 0.31, 0.998) and 31% (mean ratio 0.69, 95% CI: 0.42, 1.13) fewer caries in their permanent teeth, respectively, than children in the school districts with low number of convenience stores. We also found dose-response relationship (p for trend: 0.042).

Conclusion

Higher number of convenience stores in a school district was associated with fewer caries in permanent teeth among elementary school children. Further study elucidating the mechanism on this protective association is warranted.

Dental caries status and its associated factors among schoolchildren aged 6-8 years in Hangzhou, China: a cross-sectional study

BACKGROUND

Dental caries prevalence reaches the first peak around 6 years old. It is necessary to take effective measures to prevent and treat caries at this stage. This study investigated the prevalence and associated factors of dental caries among schoolchildren aged 6-8 years in Hangzhou City, China.

METHODS

A cross-sectional survey was conducted in Hangzhou from October 2017 to May 2018. Oral health status of schoolchildren in 1st and 2nd grades of primary schools aged 6-8 years was examined by well-trained examiners according to the WHO criteria. Questionnaires about potential caries-related factors were distributed to their parents. ANOVA test and logistic regression were conducted for the statistical analyses (α = 0.05).

RESULTS

A total of 7959 pairs of schoolchildren and their parents were invited to participate, and 5595 were included in this study according to the eligible criteria (response rate: 70.3%). The overall prevalence and mean dmft/DMFT of dental caries in the investigated schoolchildren were 52.78% and 2.11. The prevalence and mean dmft/DMFT were 39.05% and 1.63 in the deciduous teeth, while these were 21.45% and 0.48 in the permanent teeth, respectively. For the first permanent molars (FPMs), the rate of fully eruption and pit and fissure sealing (PFS) were 79.09% and 6.60%, respectively. Multiple logistic regression showed that girl (OR = 1.12, 95% CI 1.01-1.25, p < 0.05), seldom or never brush teeth (OR = 2.36, 95% CI 1.08-5.44, p < 0.05), consuming sweet food or drink once or more time a day (OR = 1.14, 95% CI 1.00-1.29, p < 0.05; OR = 1.21, 95% CI 1.07-1.36, p < 0.05), dental visit experiences (OR = 1.58, 95% CI 1.35-1.86, p < 0.001) were positively and no tooth pain in the past 12 months (OR = 0.55, 95% CI 0.38-0.80, p < 0.05) were negatively associated with caries.

CONCLUSIONS

Dental caries was prevalent among schoolchildren aged 6-8 years in Hangzhou, and was associated with gender, frequency of toothbrushing, sweet food or drink consuming, tooth pain and dental visit experiences. A large number of fully erupted FPMs did not receive timely PFS.

Association between Community Social Capital and Access to Dental Check-Ups among Elementary School Children in Japan

The association between parental social capital and a child's access to dental check-ups has been reported, but few studies have focused on dental check-ups. The present study investigated the association between parental social capital and access to dental check-ups among first-grade elementary school children (6-7 years old) in Japan. We analyzed cross-sectional data of first-grade elementary school children (6-7 years old) in Adachi City, Tokyo, Japan. Community social capital (the total score of social trust, cohesion, mutual aid) and child's dental check-ups (dental check-ups for purposes other than treatment at least once a year) were assessed by questionnaire surveys for parents of the first graders from all 69 elementary schools in 2017 (n = 5260; response rate: 81.6%) and 2019 (n = 5130; response rate: 78.8%). Multilevel Poisson regression analysis, adjusted for children's age in months, gender, mother's educational attainment, mother's employment status, having siblings, living with grandparents, and the density of dental clinics in the school district, was applied. Of the 7936 respondents included in the analysis, 82.7% of children received dental check-ups at least once a year. Individual-level social capital was positively associated with children's dental check-up utilization (prevalence ratio, PR = 0.935 per one interquartile range, IQR; 95% confidence interval, CI: 0.877, 0.996). Community-level social capital was not significantly associated with children's dental check-up utilization (PR = 0.934 per one IQR; 95% CI: 0.865, 1.008). Promoting individual-level social capital, but not community-level social capital, may improve dental check-ups among elementary school children in Japan.

69th Annual ORCA Congress 2022

The impact of the coronavirus disease 2019 (COVID-19) pandemic on dental caries is unknown. We investigated the effect of the pandemic on child dental caries in Japan by comparing the increase in dental caries from fourth to sixth grade between two cohorts, COVID-19 exposed cohort and COVID-19 unexposed cohort, using difference-in-differences analysis. Longitudinal data that followed elementary school children in Adachi City, Tokyo, were analyzed. The analysis consisted of two cohorts: those who were in fourth grade in 2016 and sixth grade in 2018 (COVID-19 unexposed cohort, N = 399) and those who were in fourth grade in 2018 and sixth grade in 2020 (COVID-19 exposed cohort, N = 3,082). Children's dental caries were examined by school dentists. A difference-in-differences analysis, adjusting for time-variant variables, i.e., household socioeconomic status, children's oral health behavior, and caregivers' psychological distress, was performed. In fourth grade, the number of Decayed, Missing, and Filled permanent Teeth (DMFT) was not different between the COVID-19 unexposed and exposed cohorts (mean = 0.241 and 0.242, respectively). In sixth grade, DMFT increased by 0.067 in the COVID-19 unexposed cohort and 0.180 in the COVID-19 exposed cohort. The interaction term of grade and cohorts for caries by difference-in-differences analysis showed that dental caries among the COVID-19 exposed cohort showed a significant increase in the number of dental caries by 0.116 (95% confidence interval 0.015, 0.216) compared to the COVID-19 unexposed cohort. Child dental caries slightly increased after the pandemic. Studies with longer follow-ups are needed to evaluate the impact of the pandemic on child dental caries.

Impacts of the COVID-19 Pandemic Exposure on Child Dental Caries: Difference-in-Differences Analysis

The impact of the coronavirus disease 2019 (COVID-19) pandemic on dental caries is unknown. We investigated the effect of the pandemic on child dental caries in Japan by comparing the increase in dental caries from fourth to sixth grade between two cohorts, COVID-19 exposed cohort and COVID-19 unexposed cohort, using difference-in-differences analysis. Longitudinal data that followed elementary school children in Adachi City, Tokyo, were analyzed. The analysis consisted of two cohorts: those who were in fourth grade in 2016 and sixth grade in 2018 (COVID-19 unexposed cohort, N = 399) and those who were in fourth grade in 2018 and sixth grade in 2020 (COVID-19 exposed cohort, N = 3,082). Children's dental caries were examined by school dentists. A difference-in-differences analysis, adjusting for time-variant variables, i.e., household socioeconomic status, children's oral health behavior, and caregivers' psychological distress, was performed. In fourth grade, the number of Decayed, Missing, and Filled permanent Teeth (DMFT) was not different between the COVID-19 unexposed and exposed cohorts (mean = 0.241 and 0.242, respectively). In sixth grade, DMFT increased by 0.067 in the COVID-19 unexposed cohort and 0.180 in the COVID-19 exposed cohort. The interaction term of grade and cohorts for caries by difference-in-differences analysis showed that dental caries among the COVID-19 exposed cohort showed a significant increase in the number of dental caries by 0.116 (95% confidence interval 0.015, 0.216) compared to the COVID-19 unexposed cohort. Child dental caries slightly increased after the pandemic. Studies with longer follow-ups are needed to evaluate the impact of the pandemic on child dental caries.

Early childhood caries prevalence and associated factors among preschoolers aged 3-5 years in Xiangyun, China: A cross-sectional study

Purpose

This study aimed to investigate the early childhood caries (ECC) prevalence among preschoolers aged 3-5 years in Xiangyun of Yunnan, China and explore the factors associated with the prevalence.

Materials and methods

A cross-sectional survey including 3-5-year-old children was conducted in Xiangyun County, China, between September and November 2020. According to the dental examination standard of the WHO 2013 criteria, the presence of ECC was recorded. Besides the dental examination for children, their parents completed questionnaires about caries-related factors, including demographic variables, family socioeconomic status, feeding, and oral health-related habits, parental dental knowledge, and the condition of dental service utilization. SPSS Statistics 25.0 (IBM, Chicago, IL, USA) was used for data analysis. Statistical significance was set at p < 0.05.

Results

The ECC prevalence among a sample of 1,280 children aged 3-5 years consisting of 665 boys and 615 girls in this study, was 74.3%, and the mean decayed-missing-filled teeth (dmft) was 4.9 ± 5.0. There were no statistically significant differences in the ECC prevalence between the sexes and among different ethnic groups. Children with different dietary and oral hygiene habits showed no significantly different prevalence of ECC. Logistic regression analysis showed that the most significantly associated factors were older age, lower family income, and worse parental perception of children's oral health status.

Conclusion

The ECC prevalence among 3-5-year-old preschool children in Xiangyun was higher than the average national ECC prevalence in China. This study implies that more attention should be given to children's caries prevention from early childhood; oral health education and promotion should be intensified to reduce the ECC prevalence and improve the oral health status of children in Xiangyun.

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.

Effectiveness of Parental Participation in a Dental Health Program on the Oral Health Status of 8-10-year-old School Children

Aim

Prevention-focused school dental health program (SDHP) is a cost-effective intervention that countries can use to lessen the problem of dental diseases by educating on oral health. The current study aims to assess the effectiveness of parental participation in an SDHP held at periodic intervals on the oral health status (OHS) of children aged 8-10 years attending a local school in Southern India.

Materials and methods

The longitudinal study was scheduled between September 2018 and June 2019 (36 weeks) in 120 participants who were healthy school children aged 8-10 years at a private school in Kelambakkam. This 36-week duration study assessed the effectiveness of school dental health education program with and without parents at every 12 weeks interval. The OHS of subjects was assessed using the standard indices [i.e., Decayed, Missing and Filled permanent teeth (DMFT), decayed, extracted, and filled primary teeth (deft), and Simplified Oral Hygiene Index (OHI-S)]. Friedman's test and Mann-Whitney U test were used for analyzing the data as indicated.

Results

In postintervention visits, children with parental participation had significantly lower caries increments than children without parental participation. While the oral hygiene index scores have improved significantly in both groups over time, the improvement in the parental participation group was greater.

Conclusion

It can be concluded that the SDHP is an educational driver that showed a constructive impression on the oral health of children. The participation of the child's parents in SDHP has significantly improved the OHS of children.

Mother’s Characteristics and Socioeconomic Status as Possible Risk Factors for Children’s Caries in Jordan

Background. Clinical oral health status of children affects their health-related quality of life. A major determinant of oral health is early childhood caries, which possesses a negative effect. Objective. The primary objective of the study was to examine the association between socioeconomic status and different mother’s characteristics and the risk of dental caries in children using the decay missing filled (DMF) score as an indicator. Methods. This was a cross-sectional descriptive study that was in the pediatric dental clinic in Hashem Ibn Al-Hussein medical military hospital in Jordan. Pearson correlation was used to examine associations between two continuous variables. Linear regression was used to detect variables that might predict the decayed missing filled teeth (dmft) score of the child. Results. A total of 264 children were enrolled in the study. Average age of children was 4.80 ± 1.99 years, and average mothers’ age was 32.74 ± 5.68. Mothers had an average DMFT score of 8.84 ± 5.39, while children had an average dmft score of 6.17 ± 4.82. There was no association between the mother’s age and the dmft score of the child (Pearson correlation = 0.08, and $P$ value = 0.215). However, a moderate, statistically significant correlation was found between the mother’s and the child’s DMFT scores (Pearson correlation = 0.418, and $P$ value = 0.001). Children who belonged to low and middle-income families had a higher dmft score compared to those that belonged to families with high income. Conclusion. Socioeconomic status of the family, mother’s habits, dental hygiene, and education level are important factors that influence the child’s oral health. Strategies that focus on children with these characteristics can help them achieve better oral health.

Early Childhood Caries Prevalence and Associated Risk Factors in Monastir, Tunisia: A Cross-Sectional Study

Purpose

The present study aimed to investigate the prevalence and risk factors of ECC among preschool children in Monastir, Tunisia.

Methods

The survey was designed as a cross-sectional study carried out between February and April 2021 in the main region of Monastir, Tunisia. A total of 381 preschool children were randomly selected using a three-stage clustered sampling technique from 10 daycares. The dental caries were diagnosed using WHO recommendations and a questionnaire in Arabic language was used to record personnel profile of the enrolled children. The chi-square test was used in bivariate analyses to assess the association between ECC and risk factors. Variables showing significant associations were included in multiple logistic regression models.

Results

The prevalence of ECC was 20% and the mean dmft score was 0.89 ± 0.24. The prevalence of ECC increased at the age of 48–59 months ([OR] 2.602; 95%CI: 1.122–2.302), the age of 60–71 months ([OR] 2.845; 95% CI: 1.128–2.072), in children with nocturnal feeding ([OR] 2,417; 95% CI: 1.340–4,358), who take sugary drinks in the bottle ([OR] 1.104; 95% CI: 1.667–2.826), stopped breast or bottle feeding after the age of 18 months ([OR] 2.417; 95% CI: 1.340–4.358), do not brush their teeth properly ([OR] 1.435; 95% CI: 1.207–2.915), had visited a dentist ([OR] 2.444; 95% CI: 2.072–1.108), and decreased in children with a more highly educated parents ([OR] 0.797; 95%CI: 0.171–0.650).

Conclusion

Given the relatively high prevalence of ECC in Tunisia, it is important to review public dental health policies and develop effective strategies to encourage changes in behavior related to the oral health of children to prevent the spread and worsening of this disease.

Caries prevalence of the first permanent molar and associated factors among second-grade students in Xiangyun of Yunnan, China: A cross-sectional study

PURPOSE

This study aimed to explore the caries prevalence of the first permanent molar (FPM) and the associated factors among second-grade students in Xiangyun of Yunnan, China.

MATERIALS AND METHODS

A cross-sectional survey was conducted in Xiangcheng Town, Xiangyun County, China, from September to November 2020. The methodology recommended by WHO was used for the dental examination. All the parents were required to complete a questionnaire to collect information on children's family background, dietary habits, oral health behaviors and parental oral health-related knowledge. The tests of significance used were the chi-square test. The association between dental caries prevalence and its associated factors was investigated using logistic regression analysis. Statistical significance was set at P < 0.05.

RESULTS

Data of 1,295 second graders consisting of 665 males and 630 females were analyzed. The caries prevalence of FPM was 47.6%, and the mean DMFT was 1.11 ± 1.394 in this sample. Among all the children with caries, the filling rate is meager, 2.6%. There were statistically significant differences in the caries prevalence of FPM among age groups. No significant difference existed between the sexes. Logistic regression analysis showed that the most significantly associated factors were: consuming desserts at least once a day, no fluoride varnish application experience, worse parental perception of children's oral health status, and incorrect parental knowledge of whether decayed primary teeth need treatment.

CONCLUSION

Caries prevalence of FPM among second-grade schoolchildren in Xiangyun was considerably higher than the average prevalence nationwide in China. As China aims to reduce dental caries to <25% of 12-year-old children in 2030, the local government of remote regions like Xiangyun needs to do much more to achieve this goal. Results of this study could provide a framework for ongoing and future public oral health programs and policy planning in Xiangyun, with particular attention to early preventive and therapeutic measures.

Being left alone at home and dental caries of children aged 6-7 years

BACKGROUND

Leaving children alone at home is considered child neglect in some countries but is not prohibited in Japan. We investigated the association between being left alone at home and dental caries of children aged 6-7 years in Japan.

METHOD

The data on first graders in all 69 public elementary schools in Adachi, Tokyo, obtained from repeated cross-sectional surveys in 2015, 2017, and 2019 were analyzed. Caregivers answered the questionnaire, and the data were linked to the information on children's dental caries evaluated in school dental health checkups (N = 12,029). Poisson regression analysis with propensity score matching (PSM) was applied to account for confounders.

RESULTS

Leaving children alone at home for ≥1 hour during the weekdays was reported by 46.4% of the caregivers, which did not vary across years. The PSM analysis showed that, compared with children never being left alone at home, children being left alone at home for ≥1 time per week had more dental caries (mean ratio (MR) 1.11; 95% confidence interval (CI), 1.02-1.21; P-value 0.016), while <1 time per week was not associated (MR 0.97; 95% CI, 0.92-1.03; P-value 0.345). The difference between those being left alone at home for <1 time per week and those being left alone for ≥1 time per week was not significant after applying Bonferroni correction (MR 1.12; 95% CI, 1.00-1.26; P-value 0.041).

CONCLUSION

Leaving children alone at home for ≥1 hour every week might be a risk factor for dental caries of children aged 6-7 years.

Association between childhood parental involvement and late-life cognitive function: A population-based cross-sectional study among cognitively intact community-dwelling older adults in Japan

AIM

Although poor childhood rearing environment is known to negatively impact late-life cognitive function, there is a scarcity of evidence on the contribution of positive parenting behaviors. The present study investigates the association between parental involvement in childhood and late-life cognitive function.

METHODS

A total of 266 older adults aged between 65 and 88 years living in Wakuya City, Miyagi Prefecture, Japan, without indication of mild cognitive impairment or dementia, participated in a survey. Parental involvement in childhood was assessed by a questionnaire, and late-life cognitive function was measured by the Japanese version of the Quick Mild Cognitive Impairment (QMCI) screening test (range: 0-100). Multiple regression analysis was performed to investigate the association, adjusting for potential confounders and mediators.

RESULTS

After adjusting for age, sex, other child-rearing environment, and academic performance in grade 6, older adults with a high level of positive parental involvement in childhood scored 6.00 (95% CI: 2.39, 9.61) points higher for the QMCI total score than those without. Parental involvement in childhood showed significant dose-response positive associations with the QMCI total score (P < 0.001), clock-drawing test score (P < 0.05), and verbal fluency score (P < 0.001). Among the six types of positive parental involvement, book reading showed a significant independent positive association with QMCI total score (P < 0.01) and logical memory score (P < 0.01).

CONCLUSIONS

Greater parental involvement in childhood, particularly book reading, was associated with better late-life cognitive function. Geriatr Gerontol Int 2021; 21: 794-801.

The Relationships Among Oral Health Practices, Early Childhood Caries, and Oral Health-related Quality of Life in Indonesian Preschool Children: A Cross-Sectional Study

OBJECTIVES

This study aimed at evaluating the relationships among oral health practices, early childhood caries (ECC), and oral health-related quality of life (OHRQoL) in five-year-old children in Indonesia.

MATERIALS AND METHODS

Overall, 266 parent-child pairs (PCPs) from preschools in Jakarta participated in a cross-sectional study. The ECC was clinically assessed by two calibrated screeners using the decayed, missing, and filled teeth (dmft) and the pufa index, which records the presence of severely decayed teeth with visible pulpal involvement (p), ulceration caused by dislocated tooth fragments (u), fistula (f), and abscess (a). The parents of the participating children completed the self-administered questionnaire comprising SOHO-5p and their oral health practices. The SOHO-5c questionnaire was used to interview the children.

RESULTS

The prevalence of ECC was 88.7%, with 35% having pufa index scores greater than 0. There were significant relationships among oral health practices, ECC, and the Scale of Oral Health Outcomes for 5-year-old children (SOHO-5) scores. There was also a significant relationship between cariogenic food consumption and the dmft and SOHO-5p scores. There was a significant relationship between ECC and the SOHO-5 scores. All the SOHO-5p variables except smile avoidance because of appearance had a significant relationship with the dmft and pufa variables. Eating and sleeping difficulties were significantly related to the dmft and pufa scores.

CONCLUSION

OHRQoL was found to be related to the dmft and pufa scores, and the parents' perceptions were more strongly correlated than the children's. No significant difference was found in the perceptions indicated by the SOHO-5p and SOHO-5c scores. This suggests that parents can be used as proxies regarding their children's OHRQoL.

There is still room for improvement in the completeness of abstract reporting according to the PRISMA-A checklist: a cross-sectional study on systematic reviews in periodontology

BACKGROUND

To evaluate the completeness of reporting abstracts of systematic reviews (SRs) before and after the publication of the PRISMA-A checklist in 2013 and to assess if an association exists between abstract characteristics and the completeness of reporting.

METHODS

A systematic search of the literature was conducted in the PubMed and Scopus databases in March 2020. The search focused on the SRs of evaluations of interventions published since 2002 in the field of periodontology. The abstracts of the selected SRs were divided into two groups before and after publication of the PRISMA-A checklist in 2013, and compliance with the 12 items reported in the checklist was evaluated by three calibrated evaluators.

RESULTS

A set of 265 abstracts was included in the study. The total score before (mean score, 53.78%; 95% CI, 51.56-55.90%) and after (mean score, 56.88%; 95% CI, 55.39-58.44%) the publication of the PRISMA-A statement exhibited a statistically significant improvement (P = 0.012*). Nevertheless, only the checklist items included studies and synthesis of the results displayed a statistically significant change after guideline publication. The total PRISMA-A score was higher in the meta-analysis group and in articles authored by more than four authors.

CONCLUSIONS

The impact of the PRISMA-A was statistically significant, but the majority of the items did not improve after its introduction. The editors and referees of periodontal journals should promote adherence to the checklist to improve the quality of the reports and provide readers with better insight into the characteristics of published studies.

Poor parenting behaviours and dental caries experience in 6- To 7-year-old children

OBJECTIVES

The association between poor parenting and dental caries in children remains unclear. We investigated the association of poor parenting with dental caries and oral health behaviour among children aged 6-7 years in Japan.

METHODS

Two waves of repeated cross-sectional surveys on children and their caregivers in Adachi City, Tokyo, were analysed. Questionnaires on parenting behaviour and the child's oral health behaviour were distributed through schools and completed by 8499 caregivers (response rate = 80.8%). The number of decayed or filled primary teeth (dft) at school dental health check-ups was linked to the survey data (N for complete case analysis = 6309). Factor analysis was performed to identify types of poor parenting: poor involvement, child abuse and lack of supervision of a child's health behaviours. The association between factor scores (z-score), the number of dft and oral health behaviour (not brushing teeth twice a day, not controlling snack eating habits and drinking juice every day) was evaluated by Poisson's regressions adjusted for covariates, including caregiver's socioeconomic status.

RESULTS

Poor involvement and lack of supervision of a child's health behaviours were positively associated with dft (mean ratio, MR [95% confidence interval, CI] =1.05 [1.03, 1.07] and 1.18 [1.16, 1.21], respectively) and unhealthy oral health behaviours. Child abuse was not associated with dft (MR = 0.99 [0.96, 1.01]) but was associated with all three unhealthy oral health behaviours (prevalence ratio, PR [95% CI] were 1.11 [1.06, 1.16], 1.11 [1.06, 1.16] and 1.06 [1.00, 1.11] for not brushing teeth, not controlling snack eating and drinking juice, respectively).

CONCLUSIONS

Poor involvement and lack of supervision of a child's health behaviours were associated with dental caries, and any type of poor parenting was associated with poor oral health behaviour among children.
