|
Objectives: The purpose of this study was to analyze the pattern of dental caries in 12-year-oldKorean adolescents through multivariate analysis.
Methods: This study used raw data from the 2015 Korea Children’s Oral Health Survey. The studyparticipants were 12-year-old adolescents. A total of 27,291 people participated in the questionnaire and oral test. The statistical analysis methods used were multidimensional scaling, clusteranalysis, and factor analysis.
Results: The result was derived after analyzing the dental caries pattern of teeth and tooth surfaceby multi-dimensional scaling method, cluster analysis method, and factor analysis. Morphologicallyhomologous teeth were gathered to form clusters. Caries occurrence showed a more similar cariesexperience pattern when the types of tooth surfaces, such as occlusal and occlusal surfaces, werethe same than when they were different.
Conclusions: Epidemiological data on the pattern of dental caries in 12-year-old adolescents can beused as basic data to create evidence-based dental caries management plans.
