This study sought to characterize the incidence and clinical progression of dentinal hypersensitivity after periodontal surgery. Fourteen patients scheduled for open-flap periodontal debridement participated in the study. Ten subjects completed the study and were evaluated for six consecutive weeks after periodontal surgery. Tactile hypersensitivity was assessed using the Yeaple probe; thermal hypersensitivity measurements were obtained using a blast of air from the air/water syringe; and subjective hypersensitivity measurements were obtained using a visual analog scale (VAS). Measurements were taken preoperatively, one week postoperatively, and once a week for the next five consecutive weeks, for a total of six measurements after periodontal surgery. Depending on the stimuli used, dentinal hypersensitivity at one week after periodontal surgery ranged from 67 to 76%. Preoperative tactile and thermal hypersensitivity incidence combined was 30% at baseline. One week after periodontal surgery, the combined incidence had increased to 79%; at six weeks postsurgery, it had decreased to 45%. This study shows that postoperative dentinal hypersensitivity increases at one and three weeks after open-flap periodontal debridement before spontaneously and gradually decreasing to levels similar to those presurgery, even in the absence of desensitizing therapy.
本研究旨在描述牙周手术后牙本质敏感的发生率及临床进展情况。14例计划接受翻瓣牙周清创术的患者参与了本研究。10名受试者完成了研究，并在牙周手术后连续六周接受评估。使用耶普尔探针评估触觉敏感性；使用空气/水注射器喷出的气流进行热敏感性测量；使用视觉模拟量表（VAS）进行主观敏感性测量。测量在术前、术后一周以及接下来连续五周每周进行一次，牙周手术后共进行六次测量。根据所使用的刺激方式，牙周手术后一周牙本质敏感率在67%至76%之间。术前触觉和热敏感性发生率在基线时合并为30%。牙周手术后一周，合并发生率增至79%；术后六周，降至45%。本研究表明，即使在未进行脱敏治疗的情况下，翻瓣牙周清创术后1周和3周牙本质敏感会增加，之后会自发逐渐降至术前水平。
