Efficacy of High-Level Laser Therapy in Managing Oral Mucositis Among Pediatric Patients Undergoing Hematopoietic Stem Cell Transplantation: A Randomized Controlled Clinical Trial

The goal of this clinical trial is to learn if high-level laser therapy can manage oral mucositis in pediatric patients undergoing hematopoietic bone marrow transplantation. The main question it aims to answer is :

Is high-level laser therapy effective as a treatment for oral mucositis in pediatric hemopoietic stem cell transplant patients? Researchers will compare patients receiving basic oral care to see the effect on the WHO oral mucositis scale.

Participants will be subjected to high level laser on lesion sites .

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: High power laser therapy group
Pediatric bone marrow transplantation patients with oral mucositis will receive high-power laser therapy once daily for four consecutive days. The laser parameters will be a wavelength of 660 to 970 nm, of power 3.2 w, pulsed at 50% duty cycle, spot size of 1 cm2, for 230 sec, defocused mode.
high power laser therapy once daily for four consecutive days with wavelength 660 to 970 nm, power 3.2 w, and duration of 230 seconds at 50% duty cycle
Other Names:
  • Photobiomodulation therapy
  • Laser biostimulation
Active Comparator: Basic oral care group
Pediatric bone marrow transplantation patients with oral mucositis will receive standard basic oral care. Local methods: mouth rinse chlorohexidine three times a day, sodium bicarbonate mouthwash.
patients will receive local methods: cholorohexidine mouthwash as well sodium bicarbonate mouthwash
Other Names:
  • conventional therapy

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Oral mucositis score
Time Frame: at baseline (day 1), day 7, and day 11 from the start of treatment
World Health Organization (WHO) scale of oral mucositis will be used to describe the lesions at baseline, day 7 and day 11, lesions are given grades from 1 to 4, with 4 being a worse outcome
at baseline (day 1), day 7, and day 11 from the start of treatment

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain score
Time Frame: at baseline (day 1), day 7, and day 11 from the start of treatment
Pain visual analogue scale will be used to measure pain level, where the patient will be given a diagram representing pain levels from 1 to 10, 10 being the highest level of pain
at baseline (day 1), day 7, and day 11 from the start of treatment
