In a sample of 2,096 randomly selected individuals of both sexes (male, 1,097., female, 999) in Gulbarga, Karnataka, dental caries was observed in about 20% individuals. The inter-sex difference in the prevalence of caries was statistically insignificant. People of the upper income group (23.2%) were affected more than the middle (20.0%) and lower income groups (17.0%). Christians (23.4%) were affected more than Hindus (20.0%) and Muslims (15.8%). Nearly one-third affected cases were in the age group 20-24 years. First molars of either jaw were more often affected than second and third molars. Mandibular first molars were affected maximum, followed by mandibular second, maxillary first and maxillary second molars. A toothwise study of caries-attack, by age, revealed increase in the frequency of carious teeth with increasing age.
在卡纳塔克邦古尔伯加随机抽取的2096名男女样本（男性1097名，女性999名）中，约20%的人观察到龋齿。龋齿患病率的性别差异在统计学上不显著。高收入群体（23.2%）比中等收入群体（20.0%）和低收入群体（17.0%）受影响更大。基督教徒（23.4%）比印度教徒（20.0%）和穆斯林（15.8%）受影响更大。近三分之一的受影响病例在20 - 24岁年龄组。上下颌的第一磨牙比第二和第三磨牙更常受到影响。下颌第一磨牙受影响最大，其次是下颌第二磨牙、上颌第一磨牙和上颌第二磨牙。按年龄对龋齿发病情况进行的逐颗牙齿研究表明，龋齿的发生频率随年龄增长而增加。
