摘要

介绍。关于发育年龄的唾液流量和唾液成分水平的数据很少,而且不完全一致。的目标。本研究的目的是比较5 - 18岁儿童未受刺激的混合唾液流速、pH值和总蛋白,以获得发育期间唾液腺功能成熟的信息。材料和方法。共检查了90名年龄在5至18岁之间的儿童和青少年(男女)。所有受试者均无龋齿(ICDA II评分为零)。采集所有患者未受刺激的混合唾液,评估pH值、总蛋白和流速。受试者被分为5-6岁、13-14岁和18岁年龄组。本研究已获大学生命伦理委员会批准(编号:Nr KB-335/2013)。结果。5-6岁儿童的唾液流率明显低于13-14岁和18岁儿童。相比之下,年轻组的pH值明显高于年龄较大的组。总蛋白以5 ~ 6岁最低,13 ~ 14岁最高,18岁最高(5 ~ 6、18岁年龄组间差异显著)。各年龄组间pH值呈下降趋势,蛋白质水平呈上升趋势。从整个被试组来看,年龄与唾液流速和蛋白质水平呈正相关,与pH值呈负相关。此外,pH值和蛋白质水平随唾液流量的增加而降低。结论。未受刺激的混合唾液流速和总蛋白增加,而pH值在5至18岁之间下降。

Salivary flow rate, total protein and pH in caries-free children and adolescents aged between 5 and 18 years
Introduction. Data regarding salivary flow and the levels of salivary components in developmental age are scarce and not fully consistent. Aim. The aim of the study was to compare unstimulated mixed saliva flow rate, pH and total protein in children aged between 5 and 18 years to obtain information on the functional maturation of salivary glands during the developmental period. Material and methods. A total of 90 children and adolescents (both sexes) aged between 5 and 18 years were examined. All subjects were caries-free (ICDA II score zero). Unstimulated mixed saliva was sampled from all patients to assess pH, total protein and flow rate. The subjects were divided into age groups 5-6, 13-14 and 18 years. The study was approved by the Bioethics Committee of the University (No. Nr KB-335/2013). Results. Significantly lower salivary flow rates were observed in 5-6 year olds vs. 13-14 and 18-year-olds. In contrast, pH values were significantly higher in the youngest group compared to older age groups. Total protein was the lowest in 5-6 year olds, higher in 13-14 year olds and the highest at the age of 18 years (significant difference between age groups of 5-6 and 18 years). A decreasing trend in pH values and an increasing one in protein levels were observed between the age groups. Considering the entire group of subjects, a positive correlation between age and salivary flow rate and protein levels, and a negative correlation with pH were found. Moreover, pH and protein levels decreased with increasing salivary flow. Conclusions. Unstimulated mixed saliva flow rate and total protein increase, while pH levels decrease between the ages of 5 to 18 years.
