Abstract

Objectives
The objective of this study was to analyze dental caries incidence in the permanent teeth of 12-year-old children.
Methods
This study used the raw data from the 2015 Korean children’s oral health survey. Participants of the research were 12-year-old children in their first year of middle school. A total of 27,291 people participated in the questionnaire and oral examination. Statistical analysis was performed using complex samples frequency analysis and contingency coefficient phi (φ).
Results
Dental caries predominately developed symmetrically with a higher tendency for left-right symmetry than for maxillary-mandibular symmetry in the mouth. The incidence of dental caries between adjacent teeth had a statistically significant correlation and was highest in the first and second premolars.
Conclusions
Information on symmetry in the development of dental caries and the association of dental caries incidence between adjacent teeth of 12-year-old children should be actively utilized when establishing evidence-based dental caries management plans.
