摘要
目的:通过Greene和Vermillion提出的简化口腔卫生指数(OHI-S)来量化口腔生物膜,并将其与无口腔健康问题的儿童进行比较。材料和方法:该研究包括48名在南克鲁塞罗大学儿科牙科诊所接受治疗的4-9岁儿童,由一名经过培训和校准的检查员根据O'Brien指数诊断牙齿侵蚀进行检查,其中24名儿童有牙齿侵蚀病变,24名儿童没有这种口腔健康问题。随后,儿童接受了ohi评估的指导和标准化。数据采用泊松单变量logistic回归分析。计算患病率(PR)值和95%置信区间(CI 95%)。结果:有牙蚀组儿童的ohs平均值(标准差)为1.19(0.38),低于无牙蚀组儿童的1.73(0.44)。牙齿上生物膜的数量与牙齿侵蚀的存在相关(OR 95% CI = 0.393;0188-0822), p值= 0.013。在WSL维度降低方面,两组间差异无统计学意义(p = 0.931)。结论:与没有口腔健康问题的儿童相比,有牙齿侵蚀的儿童的生物膜数量明显减少,牙齿生物膜可能是防止酸攻击和牙齿侵蚀发展的一个可能的保护因素。
Quantification of Dental Biofilm in Children with Dental Erosion
Objective: To quantify dental biofilm through the simplified oral hygiene index (OHI-S) proposed by Greene and Vermillion in children with dental erosion comparing them to children without this oral health problem. Material and Methods: The study included 48 children aged 4-9 years treated at the Clinic of Pediatric Dentistry of the Cruzeiro do Sul University, examined by a single trained and calibrated examiner according to O'Brien index for the diagnosis of dental erosion, in which 24 children had erosion lesions in teeth and 24 children did not have this oral health problem. Later, children received guidance and standardization for the OHI-S evaluation. Data were analyzed by the Poisson univariate logistic regression. Prevalence ratio (PR) values and 95% confidence intervals (CI 95%) were calculated. Results: The mean (standard deviation) of the OHI-S of children who had dental erosion was 1.19 (0.38), lower than children in the group without dental erosion 1.73 (0.44). The amount of biofilm on teeth was associated with the presence of dental erosion (OR 95% CI = 0.393; 0188-0822) and p-value = 0.013. Regarding the reduction in the WSL dimension, no significant difference between groups was observed (p = 0.931). Conclusion: Children with dental erosion showed a significantly lower amount of biofilm compared to children without this oral health problem, and dental biofilm can be a possible protective factor against acid attacks and development of dental erosion.
