Research Results from Seoul National University School of Dentistry Update Knowledge of Oral Health (The role of income and frequency of dental visits in the relationship between dental sealant use and resin fillings after extended coverage: a …): Health and Medicine – Oral Health

2023 NOV 14 (NewsRx) -- By a News Reporter-Staff News Editor at Clinical Trials Daily -- Current study results on oral health have been published. According to news reporting out of Seoul National University School of Dentistry by NewsRx editors, research stated, “Prevention and treatment services use is closely associated with socioeconomic factors, such as income. This study aimed to investigate the relationship between implementing the sealant program and resin fillings restoration and to explore the role of income and frequency of dental visits in this relationship.”

Financial supporters for this research include National Health Insurance Service in The Republic of Korea.

Our news correspondents obtained a quote from the research from Seoul National University School of Dentistry: “This retrospective cohort study used the cohort database from the National Health Information Database of the National Health Insurance Service. The study population comprised 494,731 children born in 2007. A logistic regression model for the experience of resin fillings and a linear regression model for weighted utilization of them were used to identify the independent effects of dental sealants, income, and frequency of dental visits. All analyses were conducted using the SAS Enterprise Guide version 7.1 (SAS Institute Inc., Cary, NC, USA). The ratio based on income level was almost proportional in all groups except the medical aid group, which had a rate as high as that of the wealthier group. Children without sealants were 1.05 times more likely to have resin fillings than others after adjusting for income level and frequency of visiting dental clinics in the final model. However, an opposite relationship between sealant experiences and resin fillings was observed in the previous model without dental visits. The gap in the weighted resin filling scores according to socioeconomic variables showed a similar tendency.”

According to the news reporters, the research concluded: “Income and frequency of dental visits might be confounding factors for the relationship between dental sealant and resin fillings. It is necessary to consider the complex relationship between socioeconomic indicators and service use while studying oral health inequality.”
