To evaluate the salivary flow rate (SFR), pH, and buffer capacity (BC) among healthy shammah users (SU) in comparison with healthy non-shammah users (NSU). Methods: This case-control study was conducted at the College of Dentistry, Jazan University, Jazan, Kingdom of Saudi Arabia between March 2016 and May 2017. A sample of 27 SU and 30 NSU were recruited. Unstimulated saliva was collected and SFR, pH, and BC were determined. Dental health was assessed using the decay-missing-filled teeth (DMFT) index. Results: Shammah users were slightly older than NSU (28.9±6.9 versus 24.9±4.3 years). Salivary flow rate was not significantly different, but pH (6.68±0.46) and BC (5.7±2.07) were significantly lower in SU users than in NSU (7±0.37; p=0.002 versus 8.1±1.47; p less than 0.001). Conversely, the DMFT in SU users was significantly higher (7.96±5.17) compared to that of NSU (4.53±3.46; p=0.007). Salivary pH and BC were significantly and directly correlated (rs= 0.576). The former was significantly and directly correlated with SFR (rs= 0.404), but the latter was not. In contrast, BC inversely correlated with decay (rs= -0.385) and DMFT (rs= -0.399). Conclusions: Shammah use is associated with alterations in saliva quality (pH and BC). It is also associated with poor dental health either through a direct effect or mediation by altered salivary parameters.
为了评估健康的水烟使用者（SU）与健康的非水烟使用者（NSU）之间的唾液流速（SFR）、pH值和缓冲能力（BC）。方法：本病例对照研究于2016年3月至2017年5月在沙特阿拉伯王国吉赞市吉赞大学牙科学院进行。招募了27名SU和30名NSU作为样本。收集非刺激性唾液并测定SFR、pH值和BC。使用龋失补牙（DMFT）指数评估牙齿健康状况。结果：水烟使用者比非水烟使用者年龄稍大（28.9±6.9岁对24.9±4.3岁）。唾液流速无显著差异，但SU使用者的pH值（6.68±0.46）和BC（5.7±2.07）显著低于NSU使用者（7±0.37；p = 0.002对8.1±1.47；p小于0.001）。相反，SU使用者的DMFT显著高于NSU使用者（7.96±5.17对4.53±3.46；p = 0.007）。唾液pH值和BC显著正相关（rs = 0.576）。前者与SFR显著正相关（rs = 0.404），但后者无此相关性。相比之下，BC与龋齿（rs = -0.385）和DMFT（rs = -0.399）呈负相关。结论：使用水烟与唾液质量（pH值和BC）的改变有关。它还通过直接影响或唾液参数改变的介导与牙齿健康不良有关。
