To assess the dental caries experience, clinical consequences of untreated dental caries, and associated factors among 6-13 years school going children in Tiruvallur taluk of Tiruvallur district, Tamil Nadu.
The study population included a sample of 1,060 study subjects, aged 6-13 years from both government and private schools. The subjects were interviewed regarding oral hygiene practices, diet, dental visits, body mass index, income of the parents using a closed-ended questionnaire. Caries experience was assessed by recording the Pulpitis, Ulceration, Fistula, Abscess (DMFT)/dmft score and untreated carious lesion was assessed using Pulpitis, Ulceration, Fistula, Abscess (PUFA)/pufa index. Pearson's Chi-square test, independent sample t-test, Kendal tau correlation and binary logistic regression were performed to determine the relationship between DMFT, dmft, PUFA, pufa scores, and various independent factors.
Among the study subjects, the mean DMFT and dmft scores were 0.12 ± 0.45 and 0.79 ± 0.15, respectively. The mean PUFA and pufa scores were 0.02 ± 0.150 and 0.14 ± 0.55, respectively. Subjects who never visited the dentist and who belonged to underweight group had significantly 2.2 times and 2.3 times, respectively, increased chances for caries experience in deciduous dentition. Subjects who never visited the dentist and who belong to underweight group had significantly 1.8 times and 1.7 times respectively, increased chances for odontogenic infection in deciduous dentition.
Dental caries experience and odontogenic infections were found to be higher in the primary dentition compared to permanent dentition. The habit of not visiting the dentist had increased the chances of developing dental caries and odontogenic infection in primary dentition.
评估泰米尔纳德邦蒂鲁瓦勒尔区蒂鲁瓦勒尔镇6至13岁学龄儿童的龋齿患病情况、未经治疗的龋齿的临床后果及相关因素。
研究人群包括1060名6至13岁的研究对象，来自政府和私立学校。使用封闭式问卷就口腔卫生习惯、饮食、看牙情况、体重指数、父母收入等方面对研究对象进行访谈。通过记录牙髓炎、溃疡、瘘管、脓肿（DMFT）/dmft评分来评估龋齿患病情况，使用牙髓炎、溃疡、瘘管、脓肿（PUFA）/pufa指数评估未经治疗的龋损情况。采用Pearson卡方检验、独立样本t检验、肯德尔tau相关性分析和二元逻辑回归分析来确定DMFT、dmft、PUFA、pufa评分与各种独立因素之间的关系。
在研究对象中，平均DMFT和dmft评分分别为0.12±0.45和0.79±0.15。平均PUFA和pufa评分分别为0.02±0.150和0.14±0.55。从未看过牙医且体重过轻的研究对象乳牙列患龋的几率分别显著增加2.2倍和2.3倍。从未看过牙医且体重过轻的研究对象乳牙列发生牙源性感染的几率分别显著增加1.8倍和1.7倍。
与恒牙列相比，乳牙列的龋齿患病情况和牙源性感染更为严重。不看牙医的习惯增加了乳牙列患龋和发生牙源性感染的几率。
