This study was conducted to examine the oral condition and the salivary and microbiological parameters associated with dental caries in 62 children with cerebral palsy, who came from households of low socioeconomic status (Study Group). This group had mixed (6 to 11 years old) and permanent (11 to 16 years old) dentition. Dental examinations were performed to measure dental caries, plaque index, salivary levels of mutans streptococci and lactobacilli, salivary flow rate, pH of stimulated saliva, and buffer capacity of saliva. A group of 67 non-handicapped children from similar socioeconomic backgrounds also were examined using these parameters (Control Group). Data were analyzed statistically by non-parametric tests and by correlation. The results showed that children with cerebral palsy who had permanent dentitions had a higher mean decayed, missing and filled surfaces index, as well as a higher plaque index for both sexes. Microbiological examination revealed higher levels of mutans streptococci among Study Group subjects with mixed dentition than in the Control Group. Also, lactobacillus counts were higher in the Study Group, regardless of sex or dentition. With respect to salivary flow rate, pH and buffering capacity, lower mean values were obtained for the Study Group.
本研究旨在调查62名来自社会经济地位较低家庭的脑瘫儿童（研究组）的口腔状况以及与龋齿相关的唾液和微生物学参数。该组儿童处于混合牙列期（6至11岁）和恒牙列期（11至16岁）。进行了口腔检查，以测量龋齿、菌斑指数、变形链球菌和乳酸菌的唾液水平、唾液流速、刺激唾液的pH值以及唾液的缓冲能力。还使用这些参数对一组来自相似社会经济背景的67名非残疾儿童进行了检查（对照组）。通过非参数检验和相关性分析对数据进行统计分析。结果显示，恒牙列期的脑瘫儿童的平均龋失补牙面指数较高，且男女的菌斑指数均较高。微生物学检查显示，混合牙列期的研究组受试者中的变形链球菌水平高于对照组。此外，无论性别或牙列情况如何，研究组中的乳酸菌计数均较高。关于唾液流速、pH值和缓冲能力，研究组的平均值较低。
