Tooth extraction may be an unpleasant and painful experience for children, Post-extraction wound healing. Low-level laser therapy (LLLT) is a widely used adjuvant treatment for wound healing, resulting in both an increase in cell number and an increase in cell metabolism. HA it is an important component of the extracellular matrix and a constituent of the neural, connective, and epithelial tissues.
Children aged from six to ten years.
Children of both genders.
Children with badly decayed first permanent molar beyond repair and indicated for extraction.
Parents acceptance to participate in the study.
Medically compromised children.
Uncooperative children.
Children who will not attend the follow up visits
Parallel
Low-Level Laser Therapy
DeviceA 980 nm diode laser will be applied immediately after extraction of the first permanent molar. The laser will be used in continuous mode at 0.5 W, with a total energy of 300 J, applied for 60 seconds at three points around the extraction socket.
Hyaluronic Acid (HA)
DrugHyaluronic acid gel will be applied directly into the extraction socket immediately after tooth removal.
wound size
Wound size unit of measure : mm (millimeters) (mesiodistal and buccolingual dimension of each socket).
Tissue Color Changes
Gingival color assessed using the Landry, Turnbull, and Howley Index (normal vs inflamed). Unit of Measure: Binary (normal / inflamed)
Bleeding Upon Palpation
Presence or absence of bleeding when palpating the extraction site. Unit of Measure: Binary (yes / no)
Pus Presence
Presence or absence of pus at the extraction site. Unit of Measure: Binary (yes / no)
Pain Level During Application
Pain assessed using Wong-Baker Faces Pain Rating Scale (0 = no pain, 10 = worst pain). (0 = no pain, 10 = worst pain). Higher scores indicate worse outcomes.
