The case histories of two patients are presented to demonstrate use of soft mouthguard appliances as carriers for desensitizing dentifrice when restoration of the teeth or application of desensitizing agents is clinically impractical. Potassium nitrate in dentifrice form was a readily available source of potassium ions for altering pulpal nerve sensitivity. Both patients had factitious habits that exacerbated dentinal hypersensitivity and required acute care.
本文介绍了两名患者的病历，以证明当牙齿修复或应用脱敏剂在临床上不切实际时，使用软质护齿器作为脱敏牙膏的载体。牙膏形式的硝酸钾是改变牙髓神经敏感性的钾离子的现成来源。两名患者都有做作习惯，这加剧了牙本质过敏，需要紧急护理。
