Dental caries is the most common oral disease in preschool children. It is considered to be due to multifactorial etiology, affecting primary molars with various caries patterns.
The aim of the study was to determine prevalence and patterns of dental caries in primary molars of preschool children. Prevalence and patterns of dental caries were correlated with age and gender.
The study design adopted was analytical observational study.
Caries examination was done using plain mouth mirror, probe, and tweezers with cotton pellets under standardized environment. Children's age was measured in years, and the age in years and months were merged with nearest round off number.
Obtained data were subjected to statistical analysis using SPSS software. Test for significance was done with the help of Chi-square test.
In Maxilla, max. rt 2nd molars ( value = 0.036), max rt 1st molars ( value = 0.035), max lt 1st primary molars (0.095), and max lt 2nd primary molars ( value = 0.005) showed significantly different caries patterns at different ages of preschool children, while no significant differences were observed in caries patterns in male and female gender. In mandible, man. lt 2nd primary molars ( value = 0.005), and man. rt 2nd primary molars ( value = 0.004) showed significantly different caries patterns in different ages of preschool children, while Mand. Lt 1st primary molars ( value = 0.389) and Mand. Rt 1st primary molars ( value = 0.272) showed nonsignificant differences in caries patterns with different ages of preschool children. A nonsignificant difference in caries patterns was noted in male and female gender.
Mandibular primary molars were more vulnerable for caries development when compared to maxillary primary molars in preschool children. The number of caries patterns present in mandibular and maxillary primary molars, were as follows: Mn. Rt 1st PM > Mn. 1st Lt PM & max lt 1st PM > max lt 2nd PM and max rt 1st PM > Mn. Rt 2nd PM > Mn. Lt 2nd PM > max rt 2nd PM.

龋齿是学龄前儿童最常见的口腔疾病。它被认为是由多因素病因引起的，影响着具有各种龋病模式的乳磨牙。
本研究的目的是确定学龄前儿童乳磨牙龋齿的患病率和模式。龋齿的患病率和模式与年龄和性别相关。
采用的研究设计为分析性观察研究。
在标准化环境下，使用普通口腔镜、探针和带有棉球的镊子进行龋齿检查。儿童年龄以岁为单位测量，年龄的年数和月数合并为最接近的整数。
使用SPSS软件对获得的数据进行统计分析。借助卡方检验进行显著性检验。
在上颌中，右上第二乳磨牙（值 = 0.036）、右上第一乳磨牙（值 = 0.035）、左上第一乳磨牙（0.095）和左上第二乳磨牙（值 = 0.005）在学龄前儿童的不同年龄阶段显示出显著不同的龋病模式，但在男性和女性的龋病模式中未观察到显著差异。在下颌中，左下第二乳磨牙（值 = 0.005）和右下第二乳磨牙（值 = 0.004）在学龄前儿童的不同年龄阶段显示出显著不同的龋病模式，而左下第一乳磨牙（值 = 0.389）和右下第一乳磨牙（值 = 0.272）在学龄前儿童的不同年龄阶段的龋病模式差异不显著。在男性和女性的龋病模式中观察到无显著差异。
与学龄前儿童的上颌乳磨牙相比，下颌乳磨牙更容易发生龋齿。下颌和上颌乳磨牙中存在的龋病模式数量如下：右下第一乳磨牙 > 左下第一乳磨牙 & 左上第一乳磨牙 > 左上第二乳磨牙 和 右上第一乳磨牙 > 右下第二乳磨牙 > 左下第二乳磨牙 > 右上第二乳磨牙。
