Evaluation of the Efficacy of Diode Laser in Maturogenesis of Immature Teeth with Necrotic Pulps: An in Vivo Study “Part One”.

Abstract

Context: The present study was performed to evaluate the Efficacy of Diode Laser in maturogenesis of
Immature Teeth with Necrotic Pulps in comparison to conventional technique of revascularization using triple
antibiotic mix. Immature necrotic permanent maxillary anterior teeth of medically free patients 8-16years
old were used to perform regenerative endodontic procedures (revascularization) and divided into 3 groups
(n = 10) : group I: Ten teeth were disinfected by triple antibiotic paste then Revascularization was done
using the standard method. Group II: Ten teeth were Laser disinfected; Revascularization was done using the
standard method. Group III: Ten teeth were disinfected by triple antibiotic paste then Revascularization was
done using the standard method followed by diode laser bio-stimulation. Follow-up was done at 3, 6, 9 and
12 months intervals and included clinical examination for signs and symptoms and radiographic evaluation
for increase in root length, increase in root thickness, a decrease in apical diameter, and a decrease in lesion
size, and the antibacterial efficacy of the Diode laser (980) nm and triple antibiotic disinfection method
on the colony forming units.It was resulted that, the colony forming unit’s results reveled non-significant
difference in percent change after treatment between triple antibiotic paste and laser disinfection. It was
concluded that: Diode laser irradiation seems to be a valuable tool in the eradication of polymicrobial nature
of root canal infection. Diode laser could be used instead of triple antibiotic paste for disinfection of root
canals in revascularization. Diode laser decontamination showed no teeth discoloration as opposed by the
triple antibiotic paste.
