Dental Health Status and Oral Health Care in Nursery School-Aged Children and their Parents Living in Poznan (Poland)

Dental Utilization Stratified by the Purpose of Visit: A Population-Based Study in Japan

BACKGROUND

This study aimed to provide a stratified description of dental visit utilisation by Japanese residents based on patient age, sex, prefecture, and the purpose of the visits.

METHODS

This cross-sectional study used the National Database of Health Insurance Claims of Japan to identify participants visiting dental clinics in Japan (April 2018-March 2019). Dental care utilisation by populations stratified by age, sex, and prefecture was assessed. We estimated the slope index of inequality (SII) and relative index of inequality (RII) to evaluate regional differences based on regional income and education.

RESULTS

Amongst the Japanese population, 18.6% utilised preventive dental care visits; 59,709,084 participants visited dental clinics, with children aged 5 to 9 years having the highest proportion. SII and RII were higher for preventive dental visits than those for treatments in all settings. The largest regional differences for preventive care were observed in SII of children aged 5 to 9 years and in RII of men in their 30s and women aged 80 years and older.

CONCLUSIONS

This nationwide population-based study revealed that the proportion of people utilising preventive dental care in Japan was low, with regional differences. Preventive care needs to be more easily accessible and available to improve the oral health of residents. The above findings may provide an important basis for improving policies related to dental care for residents.

Exploring the Relationships between Children's Oral Health and Parents' Oral Health Knowledge, Literacy, Behaviours and Adherence to Recommendations: A Cross-Sectional Survey

Although preventable, early childhood caries (ECC) is a burdening condition in all WHO regions, with Poland being one of the most affected countries in Europe. Effective home-based prevention of ECC is available and recommended by several expert bodies. Therefore, we wanted to determine how well parents were following selected oral health recommendations in preschool children. Additionally, we wanted to determine which socioeconomic factors influenced such practices the most, and how parents' oral health literacy and behaviours affected the oral hygiene and oral health status of their children. A cross-sectional survey involving 2338 parents and caregivers of children from 167 kindergartens was performed. Children's oral hygiene and oral health status were found to be associated with parents' education and economic status. They were also strongly influenced by parental health literacy and behaviours. With respect to recommendations for preschoolers, the lowest adherence was found in the use of fluoride toothpaste and its age-appropriate amount, supervision of toothbrushing, and refraining from eating after last toothbrushing. The improvement in these areas could be achieved thanks to the involvement of health professionals such as gynaecologists, midwives, and primary care personnel in efforts aimed at increasing parents' oral health knowledge and literacy.

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.

Clinical Consequences of Dental Caries, Parents' Perception of Child's Oral Health and Attitudes towards Dental Visits in a Population of 7-Year-Old Children

This cross-sectional study aimed to assess the occurrence of the consequences of dental caries and factors affecting dental service utilization in a population of 7-year-old children. The research included oral examination of 7-year-old schoolchildren and socio-medical study of their parents/legal caregivers. It was carried out in five primary schools of two provinces, i.e., Greater Poland and Lubusz. Dental examination was performed in accordance with World Health Organization (WHO) recommendations. The socio-medical study consisted of questionnaires with close-ended questions concerning socioeconomic characteristics of the family, reasons and time of the last visit at the dental office, consequences of child’s oral health problems, parents’ attitude towards dental visits, and parental opinion about their child’s teeth. Factors affecting utilization of dental services were statistically analyzed using univariate logistic regression assuming p < 0.05. The pufa index of examined children ranged from 0 to 7 (mean 0.80 ± 1.49), while the dmf index ranged from 0 to 14 (3.86 ± 3.32). Low financial burden of oral health expenditures and university education of at least one of the parents significantly increased the chance of visiting a dentist despite lack of pain (OR = 3.0 and 2.5, respectively). In spite of the availability of free dental care for children, socioeconomic factors still determine the utilization of dental services in Poland. Poor oral health status of examined population and negligence of regular dental check-ups emphasize a need to strengthen oral health literacy of parents and children, promoting proper attitudes towards dental care.
