OBJECTIVE
This study aimed to determine the relative amounts of Streptococcus mutans (SM) and lactobacilli (LBs) and their relationship with dental caries among a Yemeni adult population.
RESULTS
A positive correlation appeared between SM and LB counts from saliva and caries tissue samples and the decayed, missing and filled teeth (DMFT) score (p < 0.05). There was a significant correlation between SM and LBs in caries tissue (p < 0.05). However, there was no significant difference between SM and LBs isolated from saliva samples (p > 0.05). The number of SM and LBs in subjects with active caries was significantly higher than that in those without active caries (p < 0.05). There was no significant difference between the daily habits and SM and LB or DMFT scores (p > 0.05), except for a significant difference between brushing frequency and DMFT score (p < 0.05).
目的
本研究旨在确定也门成年人群中变形链球菌（SM）和乳酸杆菌（LBs）的相对数量及其与龋齿的关系。
结果
唾液和龋组织样本中的SM和LB计数与龋失补牙（DMFT）评分之间呈正相关（p < 0.05）。龋组织中SM和LBs之间存在显著相关性（p < 0.05）。然而，从唾液样本中分离出的SM和LBs之间无显著差异（p > 0.05）。有活动性龋齿的受试者中SM和LBs的数量显著高于无活动性龋齿的受试者（p < 0.05）。日常习惯与SM、LB或DMFT评分之间无显著差异（p > 0.05），但刷牙频率与DMFT评分之间存在显著差异（p < 0.05）。
