该研究的目的是分析龋齿保护因素,唾液参数,唇裂和/或腭裂(CL/P)高龋齿风险儿童的微生物计数。
这是一项横断面研究。
这项研究是在新德里的三级保健教学医院进行的,印度。
这项研究是在40名儿童中进行的,20患有CL/P,20岁不在5至12岁之间。
本研究包括两组中有2个或更多龋齿病变的儿童。人口统计细节,受影响牙齿的龋齿(世界卫生组织[WHO-DMFT]和国际龋齿检测和评估系统[ICDASII]的标准),龋齿保护因素,唾液参数,和微生物计数由一名校准的研究者记录。
龋齿保护因素,唾液参数,和微生物概况。
采用卡方(χ2)检验和Pearson相关性进行统计学分析。参加这项研究的所有孩子每天只刷牙一次,每天食用甜食两次以上。没有一个孩子接受过氟化物清漆。在80%的CL/P儿童和95%的无CL/P儿童中,静息唾液的缓冲能力较低。刺激唾液的微生物评估表明,随着龋齿病变的数量(DMFT评分≥4)和严重程度(ICDAS代码从1-2到5-6)的增加,两组的链球菌和乳杆菌计数均≥105个菌落形成单位/mL唾液.
患有CL/P的儿童表现出有限的龋齿防护措施和低缓冲能力的静息唾液,随着唾液刺激中唾液链球菌和乳杆菌水平升高。
The aim of the study was to analyze the caries protective factors, salivary parameters, and microbial counts in high caries risk children with cleft lip and/or palate (CL/P).
This was a cross-sectional study.
This study was conducted in a tertiary health care teaching hospital in New Delhi, India.
The study was conducted in 40 children, 20 with CL/P and 20 without aged between 5 and 12 years.
Children with 2 or more caries lesions in both groups were included in this study. Demographic details, dental caries of affected teeth (World Health Organization criteria for Decayed Missing Filled Teeth [WHO-DMFT] and International Caries Detection and Assessment System [ICDAS II]), caries protective factors, salivary parameters, and microbial counts were recorded by one calibrated investigator.
Caries protective factors, salivary parameters, and microbial profile.
The Chi-square (χ2) test and Pearson correlation were used for statistical analysis. All the children participating in the study brushed their teeth only once in a day and consumed sweets more than twice a day. None of the children had ever received fluoride varnish. Resting saliva had a low buffering capacity in 80% of children with CL/P and 95% of children without CL/P. Microbial assessment of stimulated saliva showed that with the increases in the numbers (DMFT scores ≥4) and severity (ICDAS codes from 1-2 to 5-6) of caries lesions, both Streptococci and Lactobacilli counts were ≥105 colony-forming units/mL of saliva in the both groups.
Children with CL/P showed limited access to caries protective measures and low buffering capacity in resting saliva, along with elevated levels of salivary Streptococci and Lactobacilli in stimulated saliva.
