To examine the relationships between (1) the levels of each temperament traits and the levels of milk-feeding frequency, oral hygiene care and dental caries, and (2) the difference in mean numbers of decayed surfaces among temperament types.
Four hundred and ninety-three (493) 12-month-old infants were assessed for temperaments and characteristics of child-rearing practices. The data were analysed with their dental caries status at 18 months of age. The chi-squared test, Student's t test, ANOVA and Kruskal-Wallis tests were used to assess the association between temperament traits and the following variables; dental caries, oral cleaning habits and feeding frequency. Logistic regression models were used to identify the effect of temperament traits and other factors on dental caries status.
The trait of adaptability was found to associate with feeding frequency at night, while those of activity and approach/withdrawal were significantly associated with regularity of oral cleaning habits by the children's caregiver. Three of the nine temperament traits - biological rhythmicity, approach/withdrawal and mood - were significantly associated with dental caries in bivariate analysis. Biological rhythmicity and approach/withdrawal traits were significantly associated with a higher chance of having caries after adjusting for regularity of oral cleaning habits and frequency of night feeding.
Biological rhythmicity, approach/withdrawal and mood traits were related to caries in these young children.
研究（1）各气质特征水平与母乳喂养频率、口腔卫生护理及龋齿之间的关系，以及（2）不同气质类型之间龋面均数的差异。
对493名12月龄婴儿的气质和养育方式特点进行评估，并分析他们18月龄时的龋齿状况。采用卡方检验、学生t检验、方差分析和克鲁斯卡尔 - 沃利斯检验来评估气质特征与以下变量之间的关联：龋齿、口腔清洁习惯和喂养频率。使用逻辑回归模型来确定气质特征和其他因素对龋齿状况的影响。
发现适应性特质与夜间喂养频率相关，而活动和趋近/退缩特质与儿童照料者的口腔清洁习惯规律程度显著相关。在双变量分析中，九种气质特征中的三种——生物节律性、趋近/退缩和情绪——与龋齿显著相关。在调整口腔清洁习惯规律程度和夜间喂养频率后，生物节律性和趋近/退缩特质与患龋几率较高显著相关。
生物节律性、趋近/退缩和情绪特质与这些幼儿的龋齿有关。
