The aim of the study was to assess the relationship between height and dental caries among 13-year-old adolescents in schools of Bangalore, India.
A cross-sectional study was undertaken on 1900 schoolchildren aged 13 years from both government and private schools of Bangalore using stratified random sampling. Demographic data; family-related factors; and general and oral health-related factors such as frequency of sugar consumption, dietary habits, oral hygiene practices, and dental attendance were interviewed using both open-ended and close-ended questions. Anthropometric measurements for height and weight were performed. Clinical examination was done and caries was recorded using the decayed, missing, and filled teeth (DMFT) index (WHO criteria, 1997). Data were analyzed using SPSS version 21.0, and descriptive statistics including percentages, mean, and frequencies were performed. Student's -test and ANOVA were applied to find the significant differences between mean DMFT among groups. Categorical data were analyzed by Chi-square test for differences between groups. Pearson correlation coefficient was used to find the correlation among dental caries and height and body mass index (BMI).P value was set at a statistical significance level of 0.05.
The prevalence of dental caries among the study population was 36.3% which was higher among girls as compared to boys. Dental caries was found to be significantly associated with socioeconomic status, family structure, birth order, use of oral hygiene aids, mouthrinsing, last dental visit, weight, and BMI. Height and BMI showed a strong negative correlation with dental caries.
The present study showed a significant negative correlation between height and dental caries. However, since both caries and height are a dynamic phenomenon, hence a longitudinal study exploring the possible relationship should be considered.
本研究旨在评估印度班加罗尔市学校中13岁青少年的身高与龋齿之间的关系。
采用分层随机抽样法，对班加罗尔市公立和私立学校的1900名13岁学童进行了横断面研究。通过开放式和封闭式问题，询问了人口统计学数据、家庭相关因素以及一般和口腔健康相关因素，如食糖摄入频率、饮食习惯、口腔卫生习惯和看牙就诊情况。进行了身高和体重的人体测量。进行了临床检查，并使用龋失补牙指数（DMFT）（世界卫生组织标准，1997年）记录龋齿情况。使用SPSS 21.0版软件对数据进行分析，并进行了包括百分比、均值和频率在内的描述性统计。应用学生t检验和方差分析来发现各组间平均DMFT的显著差异。分类数据通过卡方检验分析组间差异。使用Pearson相关系数来发现龋齿与身高和体重指数（BMI）之间的相关性。P值设定为统计学显著性水平0.05。
研究人群中龋齿患病率为36.3%，女孩患病率高于男孩。发现龋齿与社会经济地位、家庭结构、出生顺序、口腔卫生辅助用品的使用、漱口水使用、上次看牙就诊、体重和BMI显著相关。身高和BMI与龋齿呈强负相关。
本研究表明身高与龋齿之间存在显著的负相关。然而，由于龋齿和身高都是动态现象，因此应考虑进行一项纵向研究来探索可能的关系。
