摘要
目的评价半导体激光辅助治疗中重度慢性牙周炎的临床疗效。方法采用随机、自身对照、单盲法。将10位中重度慢性牙周炎患者的左右侧牙列随机分为实验组和对照组,每个象限选取探诊深度(Probing depth,PD)≥6 mm的两个位点,共80个位点。初诊时进行龈上洁治,2周后,实验组龈下刮治(Scaling and root planing,SRP)+半导体激光(980 nm,2 W)照射30 s,对照组只进行SRP,比较治疗前及治疗后3个月PD、临床附着丧失(Clinical attachment loss,CAL)和探诊出血(Bleeding on probing,BOP)的变化。结果治疗前,两组各临床指标均无明显差异(P>0.05)。治疗后3个月,两组各临床指标均较治疗前明显降低(P<0.05),实验组PD(4.15±0.24)mm,CAL(5.45±0.28)mm,BOP阳性率20%,对照组PD(4.13±0.28)mm,CAL(5.15±0.30)mm,BOP阳性率42.5%。其中,实验组BOP阳性率明显低于对照组(P<0.05),两组PD和CAL的变化值无明显差别(P>0.05)。结论半导体激光辅助治疗中重度慢性牙周炎可以有效改善牙龈炎症,其长期疗效有待进一步研究。
Objective To evaluate the curative effects of diode laser on the treatment for moderate to severe chronic periodontitis.Methods This is a randomized,single blind clinical trial. Dentitions of 10 severe chronic periodontitis patients were randomly divided into experiment group and control group. There were two sites with probing depth( PD) ≥6 mm in each quadrant and 80 in all. At the first visit,supragingival scaling was performed. Two weeks later,each site in experimental group was treated with scaling and root planing( SRP) and diode laser( 980 nm 2 W) irradiation for 30s,while those in control group were treated with SRP only. The changes of PD,clinical attachment loss( CAL) and bleeding on probing( BOP) were recorded and compared before treatment and 3 months after treatment. Results Before treatment,there were no significant differences in clinical indicators between two groups( P > 0. 05). 3months later,all clinical indexes decreased significantly in both groups( P < 0. 05) compared with those before treatment. In experimental group,PD was( 4. 15 ± 0. 24) mm,CAL was( 5. 45 ± 0. 28) mm,and positive rate of BOP was 20% while in control group,PD was( 4.13 ±0.28) mm,CAL was( 5.15 ±0.30) mm,and positive rate of BOP was 42.5%. In addition,in experimental group,positive rate of BOP decreased significantly compared with that in control group( P < 0. 05),but at the levels of PD and CAL,there were no significant differences between these two groups( P > 0. 05). Conclusions Diode laser is an effective adjuvant treatment for moderate to severe chronic periodontitis in short term,and its long-term efficacy needs further study.
