Analysis on dental caries status of primary teeth using light sensor oral examination device

Year: 2025

Type: article

Abstract: Methods: Data for the SmarTooth were collected from March to July of 2024 in Seoul, in- volving 4,050 children aged 3~6 years.The KNHANES used raw data from 2019 and included 289 children aged 3~6 years.The number of decayed primary teeth was calculated by excluding permanent and missing primary teeth.Results: The prevalence of dental caries was 30.7% as measured by the SmarTooth device and 15.9% by the KNHANES device (p<0.001).The mean numbers of decayed primary teeth were 0.76±1.60 and 0.45±1.28,respectively, and this difference was statistically significant (p<0.001).For the SmarTooth device, the number of decayed primary teeth increased by approximately 0.25 for each additional year of age (p<0.001), and the prevalence of dental caries increased significantly by 1.46-fold (95% CI, 1.36~1.56;p<0.001). Conclusion:The SmarTooth device appears to be more sensitive than KNHANES device in detecting decayed primary teeth and determining the caries prevalence according to age.Therefore, the SmarTooth oral examination device is considered a suitable and effective device for the early detection of dental caries and oral health management.
