目的：本研究评估了乳牙龋齿的口腔内对称性，作为乳牙列龋齿模式研究的一部分。研究设计：本研究中4800名5岁儿童和4379名8岁儿童的数据来自2012年韩国全国口腔健康调查。左右乳牙的龋面与填充面Pearson相关系数（dfs）为0.436（下乳牙）~ 0.835（上乳牙中切牙），上下乳牙列的龋面与填充面Pearson相关系数（dfs）为0.084（右乳牙中切牙）~ 0.457（左乳牙第二磨牙）（P< 0.01）。结果：排除左、右第二磨牙后，上、下dfs值差异有统计学意义（P< 0.05）。左、右初级数据无龋的范围从56.4%（第一、第二初级磨牙下牙）到99.7%（下初级中切牙）。左、右乳牙单侧或多侧龋齿发生率从25.0%（下侧乳牙）到72.7%（上侧乳牙）不等。结论：乳牙龋呈双侧对称，且对称程度随同源牙组或面组的不同而不同。
Objectives: This study evaluated the intraoral symmetry of dental caries in primary teeth as part of a study of caries patterns in primary dentition. Study design: The data for 4,800 5-year-old and 4,379 8-year-old children in this study were from the 2012 Korean national oral health survey. Pearson correlation coefficients of the decayed and filled surface (dfs) values ranged from 0.436 (lower primary canines) to 0.835 (upper primary central incisors) for the right and left primary teeth and from 0.084 (right primary central incisor) to 0.457 (left primary second molar) for the upper and lower primary dentition (P< 0.01). Results: The upper and lower dfs values differed significantly (P< 0.05) when the right and left primary second molars were excluded. The left or right primary data without caries ranged from 56.4% (lower of first and second primary molars) to 99.7% (lower primary central incisors). The bilateral caries among cases with one or more in the right or left primary teeth ranged from 25.0% (lower lateral primary incisor) to 72.7% (upper primary central incisors). Conclusions: These results suggested that dental caries in primary teeth show bilateral symmetry and differences in the degree of symmetry according to the teeth set or surface set of the homologous teeth.
