Abstract

Background: The process of wound healing is a standard
physiological reaction to injuries, often resulting in the restoration
of normal function and structure in affected tissues.
Objective: This work aimed to assess and compare the
efficiency and safety of photo-biomodulation (PBM) therapy
versus saline dressing in acute wounds.
Patients and Methods: This prospective comparative randomized
clinical work had been performed on 40 participants
aged from 16 to 40 years old, both genders, with acute wounds.
Patients were divided into two equal groups: Group A (PBM
side): Treated with diode laser and Group B (control side):
Treated with saline dressing.
Results: Wound site, infection, size of the lesion at baseline
and on 7th day were insignificantly different between
both groups. Size of the lesion on the 14th day and duration of
complete wound healing were significantly lower in group A
than group B (p < 0.05). Photographic wound assessment tool
score at 14th day was significantly varied between both groups
(p < 0.001). Patient satisfaction and visual analogue scale were
significantly varied between both groups (p < 0.001). Complication
was insignificantly different between both groups.
Semi-quantitative histological scoring system on the 14th day
was significantly different between both groups (p < 0.001).
Conclusions: PBM wounds which received low level laser
therapy exhibited advantages in various aspects, including less
time needed for complete healing, reduced wound size, lower
pain scores, along with favorable results in edges, skin color
surrounding the wound, epithelization, granulation tissue, and
overall wound assessment score compared to the control side.
