童年是一面镜子，反映出成年人的倾向。本横断面研究的目的是确定3-5岁儿童错牙合畸形的患病率、有害口腔习惯以及有害口腔习惯与错牙合畸形的关系。一项横断面研究在800名年龄在3至5岁之间的学龄儿童中进行，这些儿童是从印度达旺热尔市的10所不同的公立学校随机选择的。进行咬合评估和临床检查以评估口腔习惯。获得数据后，采用卡方检验和Z检验对数据进行分析。结果显示，错牙合畸形的患病率为8.9%，各种不良口腔习惯的患病率为47.2%。舌推（29.5%）是最常见的习惯，其次是口呼吸（26.5%）。在存在有害的口腔习惯的情况下，观察到13%的儿童患有错牙合畸形。正常乳牙列的患病率在87%的儿童中观察到，即使存在的习惯。观察到的口腔习惯患病率非常显着，占47.2%，口腔习惯患病率与乳牙列咬合不正之间的相关性似乎并不强，但我们发现该年龄段的舌推压和口呼吸习惯较多，分别占29.5%和26.2%，导致咬合不正。
Childhood is the mirror which reflects the propensities of adulthood. The objective of this cross-sectional study was to determine the prevalence of malocclusion, deleterious oral habits and relationship of deleterious oral habits and malocclusions in 3-5 years old children. A cross-sectional study was conducted among 800 school children aged ranges between 3 and 5 years who were randomly selected from 10 different public schools in Davangere city, India. Occlusal assessments and clinical examination for assessing the oral habits was carried out. After obtaining the data, Chi-square test and Z-test were used to analyze the data. The results showed the prevalence of malocclusion was 8.9% and of various deleterious oral habits was 47.2%. Tongue thrusting (29.5%) was most commonly observed habit followed by mouth-breathing (26.5%). In the presence of deleterious, oral habits 13% of children were observed with the malocclusions. The prevalence of normal deciduous dentition was observed in 87% of children even in the presence of habits. Prevalence of oral habits observed was highly significant constituting 47.2% and the correlation between prevalence of oral habits and malocclusions in deciduous dentition does not seem to be strong, but we found tongue thrusting and mouth-breathing habit more in this age group constituting 29.5% and 26.2%, respectively, contributing to the malocclusion.
