Summary

The intervention in this study is to determine whether multiple applications of photobiostimulation with Nd-YAG laser improve wound healing following tooth extraction and alveolar ridge preservation. Investigators plan to assess the impact of laser treatment on wound healing by measuring salivary biomarkers, gingival wound size and surveying for the use of pain reduction and patient satisfaction. The intervention group will receive extraction and alveolar ridge preservation with Nd-YAG laser photobiostimulation on days 1, 3, and 7 following extraction and socket preservation, while the control group will receive the standard of care extraction and alveolar ridge preservation without the laser

Detailed description

Photobiostimulation, also known as low-level laser therapy (LLLT) or phototherapy, utilizes a low-level laser to increase cell proliferation, enhance cell stimulation, and reduce gingival inflammation. It has been reported that photobiostimulation enhances chemical and metabolic changes and alters cellular behavior in the tissue by light absorption. Photobiostimulation as an adjunct treatment modality can accelerate the healing process, improve patient comfort and satisfaction following dental surgical procedures, and benefit patients with compromised healing capacity. Alveolar ridge preservation (ARP) is a standard procedure to minimize alveolar bone and gingival soft tissue atrophy following tooth extraction and before dental implant placement. The healing of ARP is critical for the success of implant placement timely treatment. The ARP procedure is currently the standard practice for patients interested in dental implant treatment and involves bone grafting of the extracted socket. ARP techniques have been used for over 20 years to maintain a favorable soft and hard tissue morphology for dental implant-related restorations. The purpose of this study is to understand the impact of Nd-YAG laser photobiostimulation on wound healing when combined with tooth extraction and alveolar ridge preservation procedures.

Interventions

Type	Name	Description
OTHER	Low-level laser therapy	The low-level laser applications will be made on the same day as the standard of care treatment (day 1), and then day 3, and day 7 by a study team member who is trained in the use of the laser device. The laser photobiostimulation will be applied using LightWalker® laser (FOTONA), with following settings, Nd:YAG laser 1064 nm, MSP modality (pulse duration), 0.5 W (power), 10 Hz (frequency), 1 min/ 1 cm2 spot using Genova handpiece from buccal, lingual, and occlusal aspects. The Genova handpiece will be placed 1 cm away from gingival tissue. Participants and operators will wear glasses to protect their eyes from laser beam in all sessions.
