Abstract：
Minimally invasive nonsurgical treatment (MINST) aims to remove an etiology with minimal damage to the healthy periodontium and provide the ideal healing environment. This case series introduces the novel protocol of laser-assisted MINST (LAMINST), combining minimally invasive surgery with a dental laser. A total of 25 patients (32 teeth) with advanced periodontal disease were enrolled and received periodontal treatment by following the LAMINST protocol. Probing depth (PD), recession, clinical attachment level (CAL), bleeding on probing (BOP), plaque presence, and site mobility were evaluated preoperatively and at 6 months. Based on the periodontal evaluations, all cases were diagnosed as stage III grade C periodontitis. Six months after LAMINST, the average PD reduction was 4.44 mm and CAL improved by 4.38 mm. Baseline mobility scores of 1 (6 teeth), 2 (9 teeth), and 3 (3 teeth) decreased to 1 (5 teeth) or 0 (13 teeth). The initial prognoses of 5 (hopeless; 15 teeth), 4 (questionable; 13 teeth), and 3 (poor; 4 teeth), improved to 4 (5 teeth), 3 (12 teeth), 2 (fair; 13 teeth), and 1 (good; 2 teeth). The number of BOP sites reduced from 179 to 12, and the number of plaque sites reduced from 173 to 9. All clinical parameters were improved after LAMINST. The application of LAMINST may overcome the traditional limitations of nonsurgical treatment, such as poor accessibility.
摘要：
微创非手术治疗（MINST）旨在消除病因，对健康牙周组织的损害最小，并提供理想的愈合环境。本案例系列介绍了激光辅助MINST（LAMINST）的新协议，将微创手术与牙科激光相结合。共纳入25例（32颗牙齿）晚期牙周病患者，并按照LAMINST方案接受牙周治疗。探测深度(PD),经济衰退,临床依恋水平(CAL)，探查出血(BOP),斑块的存在，在术前和6个月时评估了站点活动性。根据牙周评估，所有病例均诊断为III期C级牙周炎.LAMINST六个月后,平均PD减少4.44mm，CAL改善4.38mm。基线活动评分为1（6颗牙齿），2（9齿）和3（3齿）减少到1（5齿）或0（13齿）。最初的预后为5（绝望；15颗牙齿），4（可疑；13颗牙齿），和3（差；4颗牙齿），提高到4（5齿），3（12齿）2（公平；13齿），和1（好；2齿）。BOP位点从179个减少到12个，斑块位点从173个减少到9个。LAMINST术后所有临床参数均得到改善。LAMINST的应用可以克服传统的非手术治疗的局限性，比如可达性差。
