研究目的: |
儿童龋病对学龄前儿童的身心发育造成了严重的不良影响。目前学界认为龋病与口腔细菌紊乱有着密切关系。因此有必要比较患病与健康儿童在口腔细菌方面的差异。在此基础上,再根据患病口腔菌群特点,开发一种能够有效防治儿童龋病的新方法是十分重要的。益生菌是一类能够对人体产生有益作用的细菌,能够有效拮抗致病菌生物膜,国外已有多项临床研究表明益生菌可有效降低降低儿童口腔中的致病菌含量并且是安全有效的。本实验室在前期研究基础上,发现植物乳杆菌CCFM8724可有效缓解动物龋病模型,但其临床效果是未知的。因此我们开展了本研究。 |

Objectives of Study: |
Children with caries have a serious adverse effect on the physical and mental development of preschool children.At present, it is believed that dental caries is closely related to oral bacterial disorders, so it is necessary to compare the differences in oral bacteria between sick and healthy children.On this basis, it is very important to develop a new method to effectively prevent and treat children caries according to the characteristics of oral microbiota.Probiotics are kinds of bacteria that can have beneficial effects on the human body and can effectively antagonize the biofilm of pathogenic bacteria. A number of clinical studies abroad have shown that probiotics can effectively reduce the content of pathogenic bacteria in children's oral cavity and are safe and effective.On the basis of our previous study, we found that Lactobacillus plantarum CCFM8724 can effectively alleviate caries in animal models, but its clinical effect is unknown.So we conducted this study. |

药物成份或治疗方案详述: |
本实验采用随机双盲实验,共招募100名重度龋病儿童(3-6岁),每组50人,分为益生菌组和安慰剂组。益生菌组服用的是植物乳杆菌CCFM8724,辅料为麦芽糊精。安慰剂组服用的是麦芽糊精。植物乳杆菌CCFM8724来源于健康人体,被认为具有降低口腔内致病菌的含量,麦芽糊精被认为没有任何效果。嘱咐病人在0,14,28,42天内来院复诊并采集样品(包括唾液和龈上菌斑)。其中唾液样品利用qPCR技术,测量游离致病菌的含量,牙菌斑样品利用16S rDNA技术,测量益生菌服用前后,对口腔菌群的影响。 |

Description for medicine or protocol of treatment in detail: |
A total of 100 children (3-6 years old) with severe caries were enrolled in this randomized, double-blind trial, with 50 children in each group. They were divided into probiotics group and placebo group.The probiotics group took Lactobacillus plantarum CCFM8724 with the excipient of maltodextrin.The placebo group received maltodextrin.Lactobacillus plantarum CCFM8724, derived from healthy humans, is thought to reduce the level of oral pathogens, while maltodextrin is thought to have no effect.Inform the patient to return to the hospital within days 0, 14, 28, and 42 to collect samples (including saliva and supragingival plaque).The content of free pathogenic bacteria in saliva samples was measured by qPCR, and the influence of probiotics on oral flora was measured by 16S rDNA technology in dental plaque samples before and after probiotics administration. |

随机方法(请说明由何人用什么方法产生随机序列): |
在比较患病与健康儿童口腔菌群差异方面,由富有经验的口腔科主任依据国际龋病检测与评估系统(ICDAS-II)标准,选择健康或龋病儿童。在植物乳杆菌CCFM8724防治儿童龋病方面,由申请注册人按照随机数字表法,将患者随机分为益生菌组或安慰剂组。安慰剂组与益生菌组的区别仅在于是否添加了益生菌。其他方面,如包装,外观,气味等方面均无区别。由医生将益生菌或安慰剂交给患病儿童家长,医生和患者家属不知道自己分的是益生菌或是安慰剂。待全部实验结束后,由申请注册人公布具体分组情况。课题负责人负责整个过程的进展及监督。 |
