PURPOSE
The aim of the study was to estimate the salivary levels of Streptococcus mutans, Lactobacilli and Actinomyces and to correlate it with dental caries experience in mixed and permanent dentition.
MATERIALS AND METHODS
The sample size comprised 110 subjects. The decayed, missing and filled teeth (DMFT) index of all the individuals participating in the study was calculated. Saliva samples were collected from patients and samples were inoculated on specific culture media and incubated for a period of 48 h. Based on colony characteristics, S. mutans, Lactobacilli and Actinomyces were identified.
RESULTS
A positive correlation exists between DMFT and S. mutans, Lactobacilli and Actinomyces in mixed dentition and permanent dentition group samples (P < 0.001).
CONCLUSION
The conclusion from the results obtained was that S. Mutans, lactobacilli and Actinomyces which are the components of the normal microbial flora of the oral cavity play an important role in the pathogenesis of dental caries and increased number of microorganisms is associated with an increased caries frequency.
目的
本研究旨在评估变形链球菌、乳酸杆菌和放线菌的唾液水平，并将其与混合牙列和恒牙列中的龋齿经验相关联。
材料与方法
样本量包括110名受试者。计算参与研究的所有个体的龋失补牙（DMFT）指数。从患者处收集唾液样本，并将样本接种在特定培养基上，培养48小时。根据菌落特征鉴定变形链球菌、乳酸杆菌和放线菌。
结果
在混合牙列和恒牙列组样本中，DMFT与变形链球菌、乳酸杆菌和放线菌之间存在正相关（P < 0.001）。
结论
所得结果的结论是，作为口腔正常微生物群组成部分的变形链球菌、乳酸杆菌和放线菌在龋齿发病机制中起重要作用，微生物数量增加与龋齿频率增加相关。
