Erbium Chromium: YSGG Laser Effect on Surgical Treatment of Chronic Periodontitis

Microbiological and Clinical Assessments of Erbium Chromium: YSGG Laser as an Adjunctive to Surgical Treatment of Chronic Periodontitis (Randomized Clinical Trial)

Microbiological and Clinical assessment of Er,Cr:YSGG laser in conjunction to open flap debridement (OFD) in treatment of chronic periodontitis through real time PCR assay for quantification of total bacterial load.

Two groups are randomly allocated (random number generation) by Microsoft excel into two groups :

1. Group (1) Open Flap debridement (OFD) surgery after conventional periodontal therapy (Scaling &Curettage and root planing) combined by Er,Cr:YSGG Laser assisted pocket therapy (ELAPT) which will be applied to pocket epithelial lining and root surface.
2. Group (2) Open Flap debridement (OFD) surgery after conventional periodontal therapy (Scaling &Curettage and root planing) will be performed.
