A study on emotionally engaging toothbrush design for children: An empirical approach based on child psychology and cognitive development

This study investigates the emotional engagement of children aged 3–12 with toothbrush color design from a psychological perspective, focusing on three distinct age groups: 3–5 years, 6–8 years, and 9–12 years. While previous research has primarily concentrated on the physical attributes of toothbrushes, this study employs a mixed-methods approach that combines quantitative surveys with qualitative interviews and observations, to analyze children's emotional responses and preferences for various toothbrush designs across different age groups. The findings reveal significant age-related differences in emotional engagement; younger children tend to prefer bright colors and playful shapes, whereas older children prioritize functionality. Additionally tactile experience and interactivity are found to play crucial roles in enhancing children's enjoyment and motivation for toothbrushing. Furthermore, the study explores the relationship between toothbrush design and children's oral health behavior, proposing an emotionally engaging toothbrush design framework that considers children's psychological needs across different age groups. This framework offers practical guidelines for designers to create toothbrushes that enhance children's brushing experience and contribute to their oral health. The study highlights the importance of emotional engagement in designing for children and offers new insights into creating user-centered products that cater to children's developmental needs, with implications for promoting children's oral health through emotionally engaging design.

Oral health care among children in Saudi Arabia: a cross-sectional study

BackgroundOral health is crucial for caries prevention. Research reported variations in oral health practices among countries and individuals. Therefore, this study aims to examine and compare oral hygiene practices among children aged 3 to 11 years old across five areas of Saudi Arabia.MethodsThis cross-sectional study includes healthy children aged 3 to 11 from five areas/regions of Saudi Arabia. A self-administered, validated parental questionnaire was constructed according to the WHO Oral Health Questionnaire for children, which inquires about the child’s socio-demographic factors, oral health evaluation, and oral hygiene practice.ResultsOut of the 1516 parents who participated, 21.2% reported their children brushing twice a day. Regression analysis found that the first-born children and those who visited a dentist displayed a significantly higher adjusted odds ratio (AOR) for parents reporting that their child practices oral health care compared to only children (AOR: 2.837; P = 0.016) and to those who did not visit a dentist in the last 12 months (AOR: 2.989; P < 0.001).ConclusionThis study highlights that only 21.2% of parents reported their children practicing excellent oral hygiene by brushing twice a day. This underscores the importance of early dental visits, customized interventions, and prevention programs that account for regional and demographic factors, such as birth order, to effectively promote oral health.

Current Status and Family Factors Influencing Caries in the Deciduous Teeth of Children 3-6 Years of Age in Families Residing in Rural Heishanzui Township.

To determine the caries status in children's deciduous teeth and examine the influence of family oral health behaviours on the caries status. This cross-sectional study included 329 children aged 3-6 years in rural Heishanzui Township, Hebei Province, China, and used a completely random sampling method. These children underwent physical and oral health examinations. The questionnaires were given to the parents and caregivers of the examined children. The prevalence of caries in the deciduous dentition among children aged 3-6 years was 80.55%, with a dmft index of 4.93. Children in the caries group ate sweets, chocolates, and carbonated drinks more frequently than did children in the caries-free group (p < 0.05). Children in the caries-free group brushed their teeth more frequently, with parents helping their children brush, more often than did those in the caries-affected group (p < 0.05). The level of parental education and annual household income also had statistically significant effects on the prevalence of caries in the two groups (p < 0.05). Logistic regression analysis revealed that the frequency of eating sweets was a risk factor for caries in deciduous teeth (odds ratio = 2.20; p < 0.05). The prevalence of caries in deciduous teeth among children aged 3-6 years in rural Heishanzui Township was high. Compared to children in the caries-affected group, the families and children in the caries-free group had better oral hygiene behaviours. Moreover, the frequency of eating sweets was shown to be a risk factor for caries in deciduous teeth in children aged 3-6 years.

Effectiveness of Plaque Removal Using Different Toothbrushes in Children - A Comparative Study.

Effective plaque control is essential for improved oral health. Advancements in mechanical plaque removal using toothbrushes still continue. One such sophisticated intervention is the app-based toothbrush, a new innovative technology that helps to track the child's brushing habits. The aim of this study is to evaluate the plaque removal efficacy of three different toothbrushes in children aged 6-8 years. A randomized controlled clinical trial was conducted among primary school children with decayed missing filled teeth (dmft) score of ≤2. Baseline plaque score was collected using Turesky modification of the Quigley and Hein Index 1 week after oral prophylaxis. Children were randomly divided into three groups. Group I received conventional toothbrush (n = 25), group II received powered toothbrush (n = 25), and group III received app-based toothbrush (n = 25). Post-intervention plaque score, toothbrush wear and bite mark scores were done at the 15th, 30th, 45th and 90th day. Participant's opinion on their toothbrushes was evaluated using a questionnaire. App-based toothbrush showed maximum plaque reduction followed by powered and conventional toothbrush. Significant reduction in plaque score was seen at 30th-, 45th- and 90th-day follow-up in group II (<0.001) and group III (<0.001). There was no appreciable difference in the toothbrush wear and bite mark score between the three groups. Children preferred app-based toothbrush in spite of the complex nature of using it.

One of the dental and oral problems that often occurs is caries. Young children are at higher risk because their ability to maintain oral hygiene is still not optimal. Caries in children causes various impacts, including obstruct children's development, thereby reducing children's intelligence levels, which in the long term will have an impact on people's quality of life. Efforts to improve dental and oral health must begin as early as possible. One effort to improve dental and oral health is to instill in children the habit of maintaining healthy teeth through counseling and training. The counseling and toothbrushing training provided in this service activity is carried out to young children supported by parents and teachers. It is hoped that this outreach activity and toothbrushing training will provide an opportunity to teach children the importance of oral health and how to care for them properly. Counseling and training were carried out to students, teachers and parents at PAUDIT Nurul Fikri Banjarmasin using a participatory approach consisting of 3 stages, namely planning, implementation and evaluation. Counseling was carried out through animated videos, banners and dental puppets. Tooth brushing training was carried out with students brushing their teeth accompanied by parents and teachers. Based on the evaluation results, it was found that all parents were able to help their children brush their teeth better, and based on the results of interviews regarding the habit of brushing their teeth at home, all parents admitted that they always accompanied their children in brushing their teeth morning and night. It is hoped that this activity will become the basis for the establishment of the Little Dentist Program.

Oral hygiene practice and home-care challenges in children with autism spectrum disorder in San Francisco: Cross-sectional study.

Autism spectrum disorder (ASD) is characterized by challenges in social interaction, communication, and stereotypical patterns of behavior. They are more likely to have tooth brushing issues and need help with routine dental care. Children with ASD could face difficulty in accessing dental care as the parents have a challenging task in finding a dentist that would treat the child with special needs. As a result, dental care is often neglected. The aims of this study are to evaluate oral hygiene practices and challenges in children with ASD and compare it with typically developing peers (TDP). The sample size of the study was 60. Parents of children aged 3-10 were recruited and divided in 2 groups with 30 in each group. Age and gender of children were matched. ASD group included children with medical diagnosis of ASD only and no other co-morbidities. Children in TDP group had no diagnosis of ASD, and reported no disability, or any other diagnosis. Parents were asked to complete the questionnaire which asked about their demographic information, child's oral care regimens, and their knowledge about dental care. Chi-squared tests and t-test were used for statistical analysis. A p-value of .05 was used for determining statistical significance. Many children with ASD (47%) had to travel more than 20 miles for their dental home compared to 13% with TDP (p<.05). Only 60% of children with ASD brushed twice a day with 70% of parents reporting that it is difficult to brush their child's teeth compared to TDP with 93% of children brush twice daily (p<.05). Significantly a smaller number of children with ASD (47%) allowed their parent to brush their teeth as compared to 93% of TSD children (p<.001). Parents of children with autism spectrum disorder travel longer distance to find a dental home and face more difficulty in maintaining their child's daily oral hygiene.

Knowledge, Attitude, and Perception of Oral Health Among Parents of Children at Risk of Infective Endocarditis: A Cross-Sectional Study.

Infective endocarditis (IE) is a serious complication primarily affecting patients withcardiac conditions. It is widely recognized that oral microorganisms contribute to the development of IE. The objective is to assess the knowledge, attitudes, and perception of parents of children at risk of IE by studying the preventive measures employed by them. A self-constructed questionnaire composed of 14 questions was distributed among parents of children aged 0-12 years with known cardiac diseases. The parents/caregivers who were attending the pediatric outpatient clinics at King Fahad Medical City (KFMC) were selected randomly. Results:A total of 112 parents responded to this questionnaire. Almost 50% of the participants in this study reported that their children do not brush their teeth regularly, with only 12.5% of them brushing twice a day. Regarding the role of parents in supervising oral hygiene, 62.5% of them stated that they only provide advice but do not watch their child brush their teeth, and only 9.8% of parents are actively involved in advising and watching their children brush their teeth. In this study, 95.5% of parents agreed that maintaining good dental health was crucial for overall body health, and 58% of the participants showed interest in receiving more education about oral health and its impact on overall well-being.To assess the statistical significance, a nonparametric Pearson's chi-square test for fitness was employed. A p-value of ≤ 0.05 was used to report the statistical significance of the results. Conclusion:While the parents demonstrated adequate knowledge of oral health, their attitudes towardit were lacking. So, both parents and children require a modification in their attitudes towarddental care and oral health.

Does Providing Story Books to Children Lead to an Improvement in Oral Hygiene in School Children: A Quasi-Experimental Study

Objective: To assess the effect of giving tooth brushing storybooks along with verbal oral hygiene (OHI) instructions on plaque levels to schoolchildren. Methodology: This quasi-experimental study was conducted in a private school in Islamabad from October to November 2022. Children in Class V were selected as the Experimental Group I (Storybooks + OHI), while Class IV children were placed in the Control Group II (OHI alone). There were 20 students in each group. Plaque levels were compared at the baseline (before intervention) and after seven days. Tooth brushing practices were recorded at the baseline. Quantitative variables, such as age and mean plaque score were reported as mean and standard deviation. Categorical variables such as gender and tooth brushing frequency were described as frequencies and percentages. Results: The mean age of the children was 9.6 + 1.08 years. A total of 16 (40%) boys and 24 (60%) girls were included in the study. Children in Group II had significantly better self-reported tooth brushing practices with 16 (80%) children brushing twice a day, as compared to 10 (50%) children from Group I (p = 0.041). There was no difference in the reduction in plaque scores between group I (0.14 + 0.21) and group II (0.08 + 0.21; p = 0.382). Conclusion: Giving story books to children is not an effective intervention to improve the oral hygiene status of children, as compared to oral hygiene instructions alone.

RISK FACTORS FOR CARIES OF TEMPORARY TEETH IN CHILDREN

Oral health is an important component of overall health. Analysis the etiological risk factors for the occurrence of early caries in children demonstrates that the greatest responsibility for the children oral health is on their parents, who must monitor the quality and regularity of children's individual hygiene, their practical skills in dental care and the right use of hygienic products to prevent or remove dental deposits.&#x0D; According to the results of the survey, we have found that mothers whose children had caries had three-fold higher pregnancy complications than mothers of children without caries.&#x0D; Breastfeeding is the most effective ways to ensure child health as it is the most balanced in terms of the necessary components needed for the proper formation of the child's organs and systems. We have found out that 84.6% of children without caries were breastfed compared to 79.3% of children with caries.&#x0D; Nutrition is important for maintaining oral health, and carbohydrates play a special role. Only 1.1% of children with caries do not overconsume sweets, and 80.4% of them eat sweets every day. While among healthy children, 13.5% do not eat sweets at all, and 34.6% consume them every day.&#x0D; Based on the information from parents, almost 90% of children of both groups brush their teeth. But 54.5% of healthy children brush the teeth twice a day, while only 35.7% of children with caries do so. Toothpaste is used by 85.3% of children without caries and by 64.2% of children having caries.&#x0D; The obtained results indicate that parents of children do not pay enough attention to maintaining the oral health by their children. This is confirmed by the results of surveys, according to which 52.5% of children with caries aged from 3 to 6 years have never visited a dentist.&#x0D; A low level of parents’ awareness about oral health is one of the risk factors for early caries in preschool children. The results of the questionnaires show an unsatisfactory situation with the awareness of adults about individual hygiene, the use of additional products by parents themselves and their children. There is a need to carry out sanitary and educational work among parents of preschool children and families planning pregnancy.

Unemployment and expenditure on health and education as mediators of the association between toothbrushing and global income inequalities

ObjectiveThe study assessed the association of country-level income inequalities with the percentage of schoolchildren toothbrushing-at-least-twice-daily; and the mediating effect of country-level unemployment rate and governmental expenditure on health and education (EH&E).MethodsThis was an ecological study. The dependent variable was country-level toothbrushing-at-least-twice-daily among 11-15-year-old schoolchildren. Data for the period 2009 to 2019 were extracted from two global surveys about schoolchildren’s health and from manuscripts identified through a systematic search of three databases. The independent variable was country-level income inequalities measured by the Gini coefficient (GC) extracted from the Sustainable Development Report 2021. The mediators were the unemployment rate and EH&E. We stratified the sample by the level of GC and assessed the correlation between the dependent and independent variables in each stratum. Linear regression was used to assess the relations between the dependent and independent variables, and mediation path analysis was used to quantify the direct, indirect, and total effects.ResultsData were available for 127 countries. The mean (SD) percentage of children who brushed-at-least-twice-daily was 67.3 (16.1), the mean (SD) GC = 41.4 (8.2), unemployment rate = 7.5 (4.7) and EH&E = 8.4 (3.3). The percentage of children brushing at-least-twice-daily had weak and non-significant correlation with GC that was positive in countries with the least inequality and negative for countries with higher levels of inequality. A greater percentage of schoolchildren brushing-at-least-twice-daily was significantly associated with higher GC (B = 0.76, 95%CI: 0.33, 1.18), greater EH&E (B = 1.67, 95%CI: 0.69, 2.64) and lower unemployment rate (B=-1.03, 95%CI: -1.71, -0.35). GC had a significant direct positive effect (B = 0.76, 95%CI: 0.33, 1.18), a significant indirect negative effect through unemployment and EH&E (B=-0.47, 95%CI: -0.79, -0.24) and a non-significant total positive effect (B = 0.29, 95%CI: -0.09, 0.67) on the percentage of schoolchildren brushing-at-least-twice-daily.ConclusionUnemployment and EH&E mediated the association between income inequality and toothbrushing. Country-level factors may indirectly impact toothbrushing.

Factors Affecting Dental Caries Experience in 12-Year-Olds, Based on Data from Two Polish Provinces.

(1) Background: Dental caries is a chronic disease that affects a child’s dentition from the first stages of life. Several factors contribute to the development of the disease, including an improper diet. This cross-sectional study aimed to identify risk factors of dental caries in 12-year-old adolescents from Greater Poland and Lubusz Provinces (Poland). (2) Material and methods: The research was conducted in adolescents from five primary schools. A questionnaire consisted of close-ended questions on socioeconomic characteristics on family, diet, and oral hygiene habits. An assessment of the dentition was carried out in accordance with World Health Organization (WHO) recommendations. In addition to cavitated carious lesions, incipient caries lesions were noted according to the International Caries Detection and Assessment System, adapted for epidemiological studies (ICDASepiDMFt). (3) Results: The mean number of teeth with untreated caries; removed due to caries; and restored because of caries (DMFt) was 1.52 ± 1.90, while the ICDASepiDMFt index amounted to 2.64 ± 2.55, respectively. Children who did not brush every day had significantly higher odds of having ICDASepiDMFt > 0 than children brushing at least once daily (OR = 10.32, 95% CI = 1.36–78.32, p = 0.0240). Adolescents who drank sweet carbonated drinks every day had significantly higher ICDASepiDMTt than children who drank sweet carbonated drinks less frequently (p = 0.0477). (4) Conclusions: The research revealed that dental caries indices of 12-year-old adolescents from Greater Poland and Lubusz Provinces depend mainly on oral hygiene behaviors. The only significant nutritional factor that differentiated the caries intensity was the daily consumption of sweet carbonated drinks.

Oral Health Behavior and Dental Caries status: A comparative study between rural and urban school-going children in Dhaka Division

Introduction: The importance of oral health in children is paramount. Proper techniques of brushing and the influence of fermentable carbohydrates in dental caries should be taught at the early childhood stage. Objective: To estimate the mean deft, DMFT, Oral health-related behavior, and practice among the selected rural and urban school-going children in Bangladesh. Materials and Methods: This was a cross-sectional study carried out among 593 (152 rural and 441 urban children) school children using the purposive sampling technique. Data were collected from 3 urban schools and 1 rural school, using an interview-based structured questionnaire and oral examination. Consent was taken both from the college authority and participants before data collection. Descriptive analysis was performed. Results and Discussion: The study was carried out among 593 school children with an age range between below 5 years to above 15 years old. The majority of the students at urban schools brush their teeth twice daily while most rural school children brush their teeth once daily. Most of the students use toothbrushes and toothpaste as cleaning aids, however, the majority of them usually brush before meals. In addition, the majority of the students at rural and urban schools do not brush their teeth after taking sweet foods. Mean deft in deciduous teeth is high among rural school children (2.07) while mean DMFT in permanent teeth is high among urban schools. Conclusion: Organized and systemic community oral health promotion should be strengthened and a prevention-oriented oral health system is needed for promoting future oral self-care practices among school children.

Introduction: Malocclusion was declared as a third priority prevailing oral health problem by World Health Organization. A timely evaluation of the factors associated with malocclusions in the primary dentition could help in the prevention and better management of occlusion-related complications.&#x0D; Objectives: This survey explored the frequency of risk factors in association with nonnutritive and oral contributors among children.&#x0D; Methodology: A pre-validated questionnaire used for this cross-sectional study conducted between October 2019 to December 2019. The study participants were children of age 10 to 16 years visiting orthodontics department of a private dental hospital in Islamabad. Convenience sampling was applied to collect data. Statistically investigation was analyzed through SPSS software version 21. Descriptive analysis involved presentation of frequency and percentages whereas inferential analysis involved chi square association test of demographics with malocclusion risk factors.&#x0D; Results: Majority of the surveyed children brush teeth once daily. Mixed method of horizontal as well as vertical style of brushing was utilized by 50.5% of the study participants. The hereditary factor from siblings was most frequently reported factor of malocclusion in current investigation. The results also indicate presence of significant association between class I, class II and class III of dental malocclusion and nonnutritive and oral habits among children (P &lt;0.05).&#x0D; Conclusion: Desire This investigation concluded that gender, age and bad oral habits are strongly associated with malocclusion of teeth. Proper attention from parents for tooth care at early age can decrease the prevalence of malocclusion.&#x0D; Keywords: Dental malocclusion, oral habits, nonnutritive habits, children.&#x0D;

CURRENT STATUS OF ORAL DISEASE AMONG 3-5 YEAR-OLD CHILDREN IN SOME KINDERGARTENS IN HUE CITY IN 2019

Background: Dental caries is a common disease and is acquired very early in children after teething. Primitive teeth play an important role in chewing, so oral disease will affect the physical development of children. The objective of the study was to investigate the current status of oral disease, the role of the mother and related factors of 3-5 year-old children. Subjects and methods: A cross-sectional descriptive study of 524 children in some preschools in Hue city and their mothers.
