				        	 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.
