Effect of photodynamic therapy and laser alone as adjunct to scaling and root planing on gingival crevicular fluid inflammatory proteins in periodontal disease: A systematic review

These findings should be considered preliminary and further studies with long-term follow up and standardized laser parameters are recommended.
