Diabetes mellitus is a chronic disease affecting many parts of the body. A number of oral diseases have been associated with diabetes mellitus with an increased risk of dental caries and periodontal disease.
The aim of the study was to evaluate the salivary pH and incidence of dental caries and periodontal status in diabetes mellitus compared to that of the normal subjects.
The study population consisted of 40 patients divided into 2 groups with group I comprising of 20 known diabetes mellitus patients and group II comprising of 20 non diabetic subjects as control group. The pH of the saliva was determined using a digital pH meter. Dental caries and periodontal status were assessed by DMFT and PDI indices respectively.
There was a decrease in the mean salivary pH of 6.51 in the study group, compared to the normal mean salivary pH of 7.88 in the control group. The mean DMFT index was higher in the study group (8.10) when compared to that of control group (1.15). The mean PDI score was also higher in the study group (4.0) as compared to that of the control group (0.45).
The results of the present study concluded that there was a significant relationship between the diabetes mellitus and increased incidence of dental caries and periodontitis and there was also a significant reduction in the salivary pH in diabetes mellitus patients, compared to that of non diabetic subjects.
糖尿病是一种影响身体多个部位的慢性疾病。许多口腔疾病都与糖尿病相关，患龋齿和牙周疾病的风险会增加。
本研究的目的是评估糖尿病患者唾液pH值、龋齿发病率和牙周状况，并与正常受试者进行比较。
研究人群包括40名患者，分为两组，第一组由20名已知糖尿病患者组成，第二组由20名非糖尿病受试者作为对照组。使用数字pH计测定唾液pH值。分别通过DMFT和PDI指数评估龋齿和牙周状况。
研究组唾液平均pH值为6.51，低于对照组正常唾液平均pH值7.88。研究组的平均DMFT指数（8.10）高于对照组（1.15）。研究组的平均PDI评分（4.0）也高于对照组（0.45）。
本研究结果表明，糖尿病与龋齿和牙周炎发病率增加之间存在显著关系，与非糖尿病受试者相比，糖尿病患者的唾液pH值也显著降低。
