Abstract: 【Objective】 To evaluate the efficacy of Nd: YAG laser therapy adjunct to subgingival scaling and root planning (SRP) for treating severe chronic periodontitis. 【Methods】 We selected patients with severe chronic periodontitis whose teeth were distributed in 4 quadrants of the mouth, with probing depth (PD) of 5-8 mm, attachment loss (AL)≥5 mm and bleeding on probing (BOP). These teeth were randomly divided into three groups: SRP group, SRP+L group (Nd: YAG laser after SRP treatment), and L+SRP group (SRP after Nd: YAG laser treatment). We recorded parameters including BOP, PD and AL of the three groups at baseline and 8 weeks after treatment and made statistical analysis. 【Results】 At 8 weeks after treatment, BOP, PD and AL of the three groups were improved than those in the baseline (P<0.05). BOP positive percentage of SRP+L group and L+SRP group significantly reduced compared with SRP group (P<0.05). PD of SRP+L group significantly decreased compared with SRP group and L+SRP group (P<0.05), for sites with PD=7 mm, SRP+L group was significantly decreased compared with SRP and L+SRP groups (P<0.05). AL of SRP group significantly decreased compared with SRP+L group and L+SRP group (P<0.05). 【Conclusion】 Severe periodontal treatment with Nd:YAG laser adjunct to SRP is more effective in reducing BOP and PD, and for deeper pockets PD is significantly decreased in SRP+L group, but there is no advantage in the improvement of AL.
