A study on the association between electric toothbrush use on calculus formation and periodontal tissue condition in Korean adults: 7th Korea National Health and Nutrition Examination Survey

Abstract

Objectives: This study aimed to assess the relationship between electric toothbrush use and the presence of community periodontal index (CPI) code calculus among Korean adults. Methods: Data from the 7th Korea National Health and Nutrition Examination Survey were analyzed. Multiple logistic regression analysis with a complex sampling design was conducted, adjusting for general characteristic factors. Analyses were performed using SPSS Statistics 29.0. Results: Among the participants, the prevalence of electric toothbrush users was 5.3%. Within this group, 4.7% had periodontal disease, whereas 5.9% did not (p=0.025). Even after adjusting for general characteristics factors in model Ⅱ of electric toothbrush use, the odds ratio remained statistically significant at 0.791 (95% CI: 0.631-0.992) in all cases. Conclusions: Electric toothbrush use appears to be associated with potential benefits in managing the CPI code calculus distribution; however, evidence supporting this notion remains insufficient. The study findings suggest that these results could be a basis for future studies related to oral hygiene products and the design of oral health promotion programs.
