Title Er:YAG Lasers Provide Little to No Improvement in Pocket Depth of Peri-implantitis
Clinical Question In an adult patient with peri-implantitis, does the use of Er:YAG lasers in conjunction with non-surgical therapy reduce pocket depth to a greater extent than non-surgical therapy alone?
Clinical Bottom Line There is insufficient evidence to determine whether ER:YAG lasers have a clinical effect in reducing pocket depth in conjunction with non-surgical therapy. Laser therapy has been compared to non-surgical therapy with equivocal results.

Key resultsWhen comparing the a six month follow-up of treatment with Er:YAG lasers and subgingival mechanical debribement, laser treatment presented a significant reduction of pocket depth (p=0.018) with no significant differences in clinical attachment loss.

Key resultsPocket depth reduction of 0.00mm (CI=95%; -0.18 to 0.19; P=0.98) was shown between surface detoxification treatment groups and laser treatment.

Comments on
The Evidence
Validity Yan: In this meta-analysis of randomized controlled trials, the number of trials, patients and individual follow-up after a selected amount of time remains unclear. Mailoa: In this systematic review, seven clinical trials and two animal studies were involved. Follow-up was conducted beyond six months of treatment in a minimum of ten patients involved. Meta-analysis was conducted.
Applicability Although ER:YAG laser treatment has been shown to reduce pocket depth compared to to non-surgical therapy, there is insufficient evidence to determine its benefit in conjunction with non-surgical therapy.
