Dental caries is one of the commonest oral diseases that require early stages of prevention and intervention. The primary organisms related to dental caries are streptococcus mutans and lactobacilli. In the past decades, some of the non-pathogenic bacteria called probiotics have been added to the food products for the beneficial effect of human health. Intake of probiotic food products has been shown to have beneficial effects on the oral tissues. Hence the present study aimed to compare the levels of salivary pH, S. mutans, B. dentium counts in children consuming probiotic and non-probiotic curd.
40 healthy caries free children were randomly allocated into two groups. First baseline salivary samples were collected from all the participants and tested for salivary pH, salivary B. dentium and S. mutans count. After collecting the baseline values test group of children were provided with probiotic curd whereas the control group were provided with non probiotic curd for 15 days. After 15 days of consumption of these dairy products, salivary samples were collected again and tested for salivary pH, salivary B. dentium and S. mutans count.
Probiotic curd was found to be more effective in reducing the colony counts of B.dentium and S.mutans. There was a marginal decrease in pH in both the groups but was well above the critical pH.
Probiotic curd showed considerable level of decrease in colony counts of B.dentium, S.mutans and salivary pH when compared to normal curd.
龋齿是最常见的口腔疾病之一,需要早期预防和干预。与龋齿相关的主要微生物是变形链球菌和乳酸杆菌。在过去几十年中,一些被称为益生菌的非致病细菌已被添加到食品中以促进人类健康。摄入益生菌食品已被证明对口腔组织有有益影响。因此,本研究旨在比较食用益生菌凝乳和非益生菌凝乳的儿童唾液pH值、变形链球菌、龋齿放线菌的数量水平。
40名无龋齿的健康儿童被随机分为两组。从所有参与者收集第一份基线唾液样本,并检测唾液pH值、唾液中龋齿放线菌和变形链球菌数量。在收集基线值后,给试验组儿童提供益生菌凝乳,而对照组儿童提供非益生菌凝乳,为期15天。在食用这些乳制品15天后,再次收集唾液样本,并检测唾液pH值、唾液中龋齿放线菌和变形链球菌数量。
发现益生菌凝乳在降低龋齿放线菌和变形链球菌的菌落数量方面更有效。两组的pH值均略有下降,但远高于临界pH值。
与普通凝乳相比,益生菌凝乳在降低龋齿放线菌、变形链球菌的菌落数量以及唾液pH值方面有显著效果。
