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 NdYAG 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.
