The purpose of this study was to compare the clinical efficacy of nonsurgical periodontal treatment with and without Nd:YAG laser (NDL) applications in smoking and nonsmoking patients with moderate chronic periodontitis (CP).
The study population consisted of 52 patients with generalized moderate CP. The study compared the clinical effects of scaling and root planing (SRP) and SRP plus NDL in periodontal pockets measuring between 4 and 6 mm of smoking and nonsmoking patients with CP. The study patients were divided into four groups: Group 1: test teeth in smoker patients (ST; n=52 teeth); Group 2: placebo teeth in smoker patients (SP; n=52 teeth); Group 3: test teeth in nonsmoker patients (NST; n=52 teeth); and Group 4: placebo teeth in nonsmoker patients (NSP; n=52 teeth). Clinical examinations were performed immediately before SRP (the baseline) as well as 1 month (R1) and 6 months (R2) after treatment.
The recovery for pocket depth (PD), gingival index (GI), and gingival crevicular fluid (GCF) volume in the NST group was higher than in both smoker groups (p<0.05). Additionally, the changes for each of these parameters in the NSP group were higher than for the SP group (p<0.05) at R1 and R2. SRP plus NDL application versus SRP application alone did not lead to significant differences in any clinical parameters or in GCF volume between the two groups of patients who smoked (p>0.05), whereas statistically significant differences existed for PD between nonsmoker groups at R1 and R2 (p<0.05).
Our results supported the idea that NDL applications provide additional benefits in the periodontal treatment of smokers.
本研究旨在比较在患有中度慢性牙周炎（CP）的吸烟和不吸烟患者中，非手术牙周治疗联合与不联合钕钇铝石榴石激光（NDL）应用的临床疗效。
研究人群包括52例患有广泛性中度CP的患者。该研究比较了在患有CP的吸烟和不吸烟患者中，深度为4至6毫米的牙周袋内进行龈下刮治和根面平整（SRP）以及SRP联合NDL的临床效果。研究患者被分为四组：第1组：吸烟患者的试验牙（ST；n = 52颗牙）；第2组：吸烟患者的对照牙（SP；n = 52颗牙）；第3组：不吸烟患者的试验牙（NST；n = 52颗牙）；第4组：不吸烟患者的对照牙（NSP；n = 52颗牙）。在SRP治疗前（基线）以及治疗后1个月（R1）和6个月（R2）进行临床检查。
NST组的牙周袋深度（PD）、牙龈指数（GI）和龈沟液（GCF）量的恢复情况高于两个吸烟组（p < 0.05）。此外，在R1和R2时，NSP组中这些参数的变化高于SP组（p < 0.05）。在两组吸烟患者中，SRP联合NDL应用与单独应用SRP相比，在任何临床参数或GCF量方面均未导致显著差异（p > 0.05），而在R1和R2时，不吸烟组之间的PD存在统计学显著差异（p < 0.05）。
我们的结果支持以下观点，即NDL应用在吸烟患者的牙周治疗中提供了额外的益处。
