The study was undertaken at Kesariyaji, located in Udaipur district of Rajasthan. There are about 3 million workers who marble mine at Rajasthan. Living conditions of these workers are substandard and most of them are immigrant workers living in tiny shacks. Majority of them belong to lower socioeconomic status with poor educational background. The present study was carried out to estimate dental caries prevalence and treatment needs of laborers working in the green marble mines of Udaipur district.
The data was collected using the methods and standards recommended by the WHO. Dentition status and treatment needs along with decayed, missing, and filled teeth (DMFT) index, and decayed, missing, and filled surfaces score were recorded. Standard error of mean was calculated for all the mean values of treatment needs. There were three examiners, who were trained before the survey for inter-examiner variability, and the reliability was tested by means of weighted kappa statistics, which was 90%.
The study population comprised 513 men in four age groups of 18-25, 26-34, 35-44, and 45-54 years, respectively.
The mean DMFT for all age groups was 3.13 with highest mean of 4.0 for the age group of 45-54 years. Mean decayed teeth were 2.60, 3.33, 1.46, and 1.5 for the age groups 15-24, 25-34, 35-44, and 45-54 years, respectively. Filled component was nil for all age groups. Most of the subjects required one surface filling with a very less proportion needing pulp care.
The missing component constituted the major part of DMFT index in the 45-54 years age group and the absence of filled component in the whole study population implies that the treatment needs of the study population are unmet. Thus, intervention in the form of oral health promotion and curative services are the need of the hour.
该研究在拉贾斯坦邦乌代浦尔区的凯萨里亚吉进行。拉贾斯坦邦约有300万从事大理石开采的工人。这些工人的生活条件不达标准，他们大多是移民工人，居住在狭小的棚屋里。他们中的大多数人社会经济地位较低，教育背景差。本研究旨在评估乌代浦尔区绿色大理石矿工人的龋齿患病率和治疗需求。
数据收集采用世界卫生组织推荐的方法和标准。记录牙列状况、治疗需求以及龋、失、补牙（DMFT）指数和龋、失、补牙面得分。计算所有治疗需求平均值的标准误。有三名检查者，在调查前接受了检查者间变异性的培训，并通过加权kappa统计检验可靠性，可靠性为90%。
研究人群包括513名男性，分别处于18 - 25岁、26 - 34岁、35 - 44岁和45 - 54岁四个年龄组。
所有年龄组的平均DMFT为3.13，45 - 54岁年龄组的平均值最高，为4.0。15 - 24岁、25 - 34岁、35 - 44岁和45 - 54岁年龄组的平均龋牙数分别为2.60、3.33、1.46和1.
