The investigator recruited patients who are found eligible to the criteria then randomly allocated into three groups (n=13)~Group I: thirteen teeth were disinfected by triple antibiotic paste then revascularization was done using the blood clot method.~Group II: thirteen teeth were Laser disinfected; revascularization was done using the the blood clot method.~Group III: thirteen teeth were disinfected by triple antibiotic paste then revascularization was done using the the blood clot method followed by diode laser bio-stimulation.~periapical x rays was taken at baseline, 3, 6, 9, and 12 months after treatment for the increase in root length and thickness, decrease in apical diameter evaluation
Recruited patients with immature permanent maxillary anterior teeth with non-vital pulp, and periapical radiolucency, age ranging from 8 to16 years old were randomly allocated into three groups (n=13): Group I, disinfected using the triple antibiotic paste, Group II, disinfection was done using diode laser, and Group III, were disinfected using the triple antibiotic paste, diode laser was used for biostimulation. All groups were evaluated for the increase in root length and thickness and decrease in apical diameter at baseline, 3, 6, 9, and 12 months after treatment
