Title 980 NM Diode Laser Adjunct To Scaling And Root Planing (SRP) Does Not Significantly Reduce Pocket Depth In Periodontal Patients As Compared With SRP Alone
Clinical Question In a patient with chronic periodontitis, does SRP with 980 nm adjunct reduce pocket depth better than SRP alone?
Clinical Bottom Line No evidence shows 980 NM Diode Adjunct to SRP reduces pocket depth more than SRP alone. (See Comments on the CAT below)

(level of evidence)
19123307Caruso/2008Periodontally involved patientsRandomized Clinical Trial
Key resultsSlight initial improvement was noted with use of 980 NM Diode adjunct therapy, but at six months, pocket depth was the same between SRP (gold standard) patients and SRP+980 nm diode laser treatment.

Comments on
The Evidence
Drop out rates, whether the study was single blind or double blind or neither were not reported. Follow-up period was adequate yet short; a longer follow-up would be preferred.
Applicability The study can be applied to patients with chronic periodontitis who have more than 5 mm pockets.

“Clinical and microbiological evaluation of high intensity diode laser adjutant to non-surgical periodontal treatment: a 6-month clinical trial” investigates impact of laser therapy in traditional non-surgical periodontal therapy in randomized split clinical trial. This supports the author’s conclusion on no benefits of diode laser in non-surgical periodontics maintenance therapy.
