Prescribe med- ications for home use. Patients were given the TwinLight® dual Nd:YAG/ Er:YAG laser periodontal treatment using a LightWalker/ Powerlase laser (manufactured by Fotona). Results The TwinLight® procedure consists of the following three steps: 1st step: De-epithelialization and decontamination Perform Nd:YAG laser sulcular debridement. Initi- ate Nd:YAG laser treatment of the inner pocket wall to remove the pocket epithelium around the entire tooth (2–4 Watts to the tissue, SP or MSP mode, 10–20 Hz). Nd:YAG handpiece strokes from side to side. Denature the inner pocket epithelium to the depth of the probe readings. Remove the denatured tissue as it collects on the fiber ending. 2nd step: Calculus removal (debriding refinishing) Perform Er:YAG laser root debridement (removal of the subgingival calculi) with a 600 µm VARIAN tip, 100–200 mJ, 10–20 Hz, QSP, SSP or MSP pulse du- ration. Handpiece strokes are up and down. Perform mechanical scaling and root planning with a piezoelec- tric or ultrasonic scaler. Biofilm removal with Er:YAG laser using an XPulse, PIPS or VARIAN 400–600 µm fiber tip, 20–50 mJ, 20–40 Hz, SSP or MSP pulse dura- tion. Handpiece surface movement. 3rd step: Clot formation Lase the pocket contents of the teeth (3–4 Watts to the tissue, VLP mode, 20 Hz) to help coagulate any blood present and to form a pocket seal. Activate the Nd:YAG laser on the out-stroke only. Approximate the wound edges. Compress the tissue with wet gauze against the tooth from both a facial and lingual direc- Four private dental practices were involved in the retro- spective collection and analysis of before and after radio- graphic images of their patients receiving the TwinLight® periodontal treatments, as collected during the period of approximately the past six years.

Discussion Due to the complementary effects of the near-infra- red (Nd:YAG: 1,064 nm) and medium-infrared (Er:YAG: Fig. 5a Fig. 5b Figs. 5a & b: Patient #5 before (a) and 22 months following TwinLight® treatment (b).
