The aim of this clinical trial was to assess the performance of a full-mouth ultrasonic debridement protocol in the treatment of severe chronic periodontitis in comparison with scaling and root planing in a quadrant-wise procedure in smokers.
The trial consisted of 30 participants presenting with periodontitis divided into 3 groups: Group FMUD - full-mouth ultrasonic debridement, i.e., one session of 45 minutes of ultrasonic instrumentation for smokers (n = 10), Group SRP- scaling and root planing performed in a quadrant-wise manner for smokers (n = 10), and Group Control - SRP for nonsmokers (n = 10), treated following the same protocol as the SRP group. The parameters evaluated were: plaque/bleeding on probing indices, probing pocket depth, relative recession, and relative probing attachment level at baseline, 45, 90 and 180 days after therapy.
Full-mouth ultrasonic debridement and scaling and root planing resulted in comparable gain of attachment 6 months after therapy. Both groups exhibited probing pocket depth reduction at all experimental periods as compared to baseline. Smokers, however, had less probing pocket depth reduction and relative probing attachment level gain compared to non-smokers, despite the mechanical protocol used (p < 0.05). Moreover, at 180 days, nonsmokers presented with fewer sites requiring re-treatment (probing pocket depth > 5 mm and bleeding on probing) than smokers (p < 0.05).
Full-mouth ultrasonic debridement and scaling and root planing result in comparable clinical outcomes for the treatment of smokers with severe chronic periodontitis. Despite the non-surgical technique used, smokers had a less favorable clinical response than non-smokers.
本临床试验旨在评估全口超声清创方案与象限式龈下刮治及根面平整术相比，在治疗重度慢性牙周炎吸烟者中的效果。
该试验纳入30名牙周炎患者，分为3组：全口超声清创组（FMUD组）——对吸烟者进行一次45分钟的超声器械治疗（n = 10）；象限式龈下刮治及根面平整组（SRP组）——对吸烟者进行象限式龈下刮治及根面平整（n = 10）；对照组——对非吸烟者进行与SRP组相同方案的龈下刮治及根面平整（n = 10）。评估的参数包括：基线、治疗后45天、90天和180天时的探诊出血/菌斑指数、探诊深度、相对退缩和相对探诊附着水平。
治疗6个月后，全口超声清创组和龈下刮治及根面平整组的附着获得情况相当。与基线相比，两组在所有实验阶段的探诊深度均降低。然而，尽管采用了机械治疗方案，但吸烟者的探诊深度降低幅度和相对探诊附着水平增加幅度均低于非吸烟者（p < 0.05）。此外，在180天时，非吸烟者需要再次治疗（探诊深度> 5 mm且探诊出血）的部位比吸烟者少（p < 0.05）。
全口超声清创和龈下刮治及根面平整在治疗重度慢性牙周炎吸烟者时临床效果相当。尽管采用了非手术技术，但吸烟者的临床反应不如非吸烟者理想。
