title: LASER curettage as adjunct to SRP, compared to SRP alone, in patients with periodontitis and controlled type 2 diabetes mellitus: A comparative clinical study.
abstract: OBJECTIVE
  To compare the effect of scaling and root planning (SRP) alone, and laser curettage as an adjunct to SRP, on the clinical parameters of patients with periodontitis and controlled type 2 diabetes mellitus.
  
  
  METHODS
  Ten patients were divided into two equal groups in a split-mouth design - Group I: SRP alone, Group II: SRP + laser curettage. The following clinical parameters were recorded: (i) Gingival index (ii) plaque index (iii) sulcular bleeding index (iv) probing depth (PD) and (v) clinical attachment level (CAL). SRP was done in one quadrant using Gracey curettes and in another quadrant SRP plus laser curettage was done. Three weeks after the therapy, the clinical parameters were recorded and the results were analyzed and the percentage of improvement were evaluated.
  
  
  RESULTS
  The results of this study indicated that both SRP and SRP + laser curettage were efficient for reducing gingival inflammation and PD. Group II showed more reduction in PD and more gain in CAL than Group I. Mean reduction in PD was 20.22% in Group I and 26.76% in Group II. Mean CAL gain is 32.5% in Group II and 22.34% in Group I.
  
  
  CONCLUSIONS
  In both the groups, gingival inflammation was reduced. When laser curettage was used as adjunct to SRP more reduction in PD and CAL was seen.
