The goal of this study was to investigate the association between tooth wear and salivary measures in a random sample of patients from practices of dentist members of a practice-based research network.
Patients completed a questionnaire on oral self-care, health, dietary habits, medications, and socio-demographic variables. Six salivary characteristics (consistency, resting salivary flow, resting salivary pH, stimulated salivary flow, stimulated salivary pH, and buffering capacity) were measured, and a dental examination included categorizing patients according to the dentist's judgment of the degree of tooth wear (i.e., none/minimal, some, or severe/extreme). Bivariate and multinomial logistic regression models were used to relate salivary characteristics and other factors to the outcome of tooth wear.
Data are reported from 1,323 patients (age range 16-97 years) from 61 practices. Patient age, gender, number of teeth, and perception of dry mouth were associated with tooth wear, but salivary and dietary factors were either weakly or not related.
The findings of this cross-sectional assessment suggest that using these salivary tests and dietary assessments in real-life clinical settings is unlikely to be useful in assessing tooth wear risk. Suggestions are offered about risk assessment for tooth wear.
Assessing a dental patient's risk of tooth wear using salivary measures and dietary assessments as described is not recommended for general dental practice until stronger evidence exists indicating its utility.
本研究的目的是在一个基于实践的研究网络中，对来自牙医成员诊所的患者随机样本进行调查，以探究牙齿磨损与唾液指标之间的关联。
患者完成了一份关于口腔自我护理、健康状况、饮食习惯、用药情况以及社会人口统计学变量的问卷。测量了六项唾液特征（黏稠度、静息唾液流量、静息唾液pH值、刺激唾液流量、刺激唾液pH值和缓冲能力），并且进行了牙科检查，包括根据牙医对牙齿磨损程度的判断对患者进行分类（即无/轻微、中度或重度/极重度）。使用二元和多项逻辑回归模型将唾液特征及其他因素与牙齿磨损结果相关联。
报告了来自61家诊所的1323名患者（年龄范围16 - 97岁）的数据。患者年龄、性别、牙齿数量和口干感知与牙齿磨损有关，但唾液和饮食因素要么关联较弱，要么无关联。
这项横断面评估的结果表明，在现实临床环境中使用这些唾液检测和饮食评估来评估牙齿磨损风险不太可能有用。针对牙齿磨损风险评估提供了相关建议。
在有更强证据表明其效用之前，不建议在一般牙科实践中使用所描述的唾液检测和饮食评估来评估牙科患者的牙齿磨损风险。
