Title Use Of Diode Lasers in Addition to Conventional Non-Surgical Periodontal Therapy Does Not Produce a Decrease in Probing Depths or Clinical Attachment Loss (CAL)
Clinical Question For patients in the initial phase of chronic periodontal therapy, does adjunctive treatment with diode lasers result in decreased probing depth and clinical attachment loss (CAL) as compared to those treated with conventional non-surgical periodontal therapy?
Clinical Bottom Line The use of diode lasers in addition to scaling and root planing does not produce a decrease in probing depths or CAL for those undergoing the initial phase of chronic periodontal treatment. A review of 9 studies including a large number of patients indicates that the combined therapy produces results comparable with conventional debridement alone.

Key resultsMeta-analysis of probing depths and CAL showed no significant benefit from the use of diode lasers: Probing depth difference in means (DiffM) = -0.11, p = 0.68, 95% CI [-0.65, 0.43]. CAL DiffM = 0.04, p = 0.80, 95% CI [-0.26, 0.34].

The Evidence
Validity: The review included a detailed search for relevant trials with strict selection parameters. Two independent reviewers assessed all studies for methodological quality. Meta-analysis was performed using a random effects model. Perspective: The 9 studies reviewed included 247 patients who were followed for up to 6 months. This is a large patient pool, but more long-term studies are indicated. The main advantage of the diode laser is the energy absorption in the soft tissues to remove the epithelial lining of the pocket without damaging hard tissues.
Applicability Studies included patients 18 and older who were in good health. The effects of smoking and systemic disease were not analyzed. The novelty of diode lasers makes them appealing to patients and clinicians, but the cost can be prohibitive, and not all models are approved for use in the US.
