Effect of Low-Level Laser Therapy on Wound Healing and Post-extraction Pain Management of Primary Molars.

Effect of Low-Level Laser Therapy on Wound Healing and Post-extraction Pain Management of Primary Molars. (a Randomized Controlled Clinical Trial)

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 18 (actual)
• Sponsor: Alexandria University · Academic / Other
• Sex: All
• Age: 5 Years – 8 Years
• Healthy volunteers: Accepted

Summary

The goal of this clinical trial is to evaluate the effect of low-level laser therapy on wound healing of primary molar teeth extraction. in children aged 5-8 years with bilateral primary molars indicated for extraction. The main questions it aims to answer are: * does low-level laser therapy affect wound healing of primary molar teeth extraction? * does of low-level laser therapy affect post-extraction pain management of primary molar.? Researchers will compare placebo group (Sham side) to Intervention side ( split mouth design). Participants will be subjected to low level laser and post-extraction instructions in the intervention side, while the placebo side will receive post-extraction instructions only, participants will come for follow up on days 3, and 7 after extraction, they will answer self-reported questionnare related to post-extraction pain , wound healing will also be measured from photographs of the extraction site using Image J soft-ware

Detailed description

The goal of this clinical trial is to evaluate the effect of low-level laser therapy on wound healing of primary molar teeth extraction. in children aged 5-8 years with bilateral primary molars indicated for extraction. this is a split mouth randomized controlled clinical trial. Each participant will have one side randomly assigned to intervention using low level diode laser at a wavelength of 660nm aimed at the extraction site 1 cm away for 60 seconds in continuous emission mode. the other side will be placebo side with just the aiming beam, in both visits the participant will be given post-extraction instructions participants will come for follow up on days 3, and 7 after extraction, they will answer an arabic self-reported questionnaire comprising 33 items that assessed pain, discomfort, analgesic consumption, daily activities, and jaw-function impairment on the night of the extraction and after 7 days, wound healing will also be measured days 3 and 7 using of the extraction site using Wound healing index by Landry, Turnbull and Howley, and wound size will be measured using Image J soft-ware from the from photographs.

Conditions

• Post-extraction Pain (PEP)
• Wound Healing
