INTRODUCTION
Salivary substitutes are gaining popularity these days because of the increase in patients with dry mouth. These substitutes must satisfy certain criteria to fulfill the patient's needs. One of these is wettability.
MATERIALS AND METHODS
One hundred fifty rectangular specimens of heat-cured denture base acrylic resin were prepared. A drop of test liquids (human saliva, distilled water, aqwet, saleva, and wet mouth) was placed over the test specimen and right and left contact angles were measured using optical contact angle machine.
RESULTS
All test liquids performed better than distilled water. Human saliva has the least contact angle followed by aqwet.
CONCLUSION
Carboxymethyl cellulose base aqwet saliva substitute was found to be best having similar contact angle values to human saliva.
引言
由于口干患者数量的增加，唾液替代品近来越来越受欢迎。这些替代品必须满足某些标准才能满足患者的需求。其中之一就是润湿性。
材料与方法
制备了150个热固化义齿基托丙烯酸树脂矩形试件。将一滴测试液体（人唾液、蒸馏水、aqwet、saleva和湿口）置于测试试件上，使用光学接触角测量仪测量左右接触角。
结果
所有测试液体的表现均优于蒸馏水。人唾液的接触角最小，其次是aqwet。
结论
发现羧甲基纤维素基aqwet唾液替代品最佳，其接触角值与人类唾液相似。
