目的：分析探讨唾液pH值及个人生活行为习惯对患龋的影响。方法筛选2013年1月—2014年1月于该院就诊的普通患者266例，作为研究对象。采集所有患者的唾液并测量其pH指标，调查患者的个人生活行为习惯，其中包括日常饮食、个人卫生及生活状态。并分析唾液pH值及个人生活行为习惯对龋齿发病的影响。结果 pH值由8下降到5时，患龋均数分别为（1.1±0.2）、（3.0±0.7）、（5.5±1.2）、（8.9±1.5），表示患者唾液pH值越高则其龋齿发生数目、发生率越低；调查结果显示零食食用频率、刷牙次数、个人卫生习惯等均为龋齿发生的相对相关影响因素，在患龋发生率上比较存在显著差异。结论个人生活行为习惯是影响儿童或成年人患龋发生的主要因素，同时唾液pH值可作为龋齿发病的独立危险因素，针对纠正患者唾液pH及改善个人生活行为习惯可有效预防及控制龋齿的发生。

Objective To analyze and investigate the influence of salivary pH and personal living habits on caries. Methods 266 patients visited our hospital from January 2013 to January 2014 were selected as the subjects. The saliva of all the patients was collected and its pH indexes were measured. The personal living habits of the patients including diet, personal health and state of life were investigated. And the influence of salivary pH and personal living habits on the incidence of dental caries was analyzed. Results The pH value decreased from 8 to 5, the number of mean decayed teeth was respectively 1.1±0.2, 3.0±0.7, 5.5±1.2, 8.9± 1.5, indicating that more higher salivary pH, more lower the number of dental caries and occurrence rate. The survey proved that snacks consumption frequency, frequency of tooth brushing and personal hygiene habits were the relative factors influencing the occurrence of dental caries, caries incidence was significant difference in comparison existence rate. Conclusion The personal liv-ing habits are the main factors affecting children or adults suffering from caries, and salivary pH value can be used as an indepen-dent risk factor for the incidence of dental caries. Correcting the pH of saliva of patients and improving their living habits can ef-fectively prevent and control the occurrence of dental caries.
