ABSTRACT

Objectives:

This study evaluated the action of low level laser therapy (LLLT) on the percentage of newly formed bone in rabbit mandibles that underwent distraction osteogenesis (DO).Study

design:

Ten rabbits underwent bone lengthening according to the following protocol Latency – 3 days;Activation – 7 days 0.7 mm/d; and Consolidation – 10 days. The control group was composed of 4 rabbits. The experimental group, composed of 6 rabbits, received infrared GaAlAs LLLT (ë=830 nm, P=40 mW) according to the following protocol point dose of 10 J/cm2 applied directly on the bone site that underwent DO during boneconsolidation at 48-hour intervals.

Results:

The percentage of newly formed bone was greater in the LLLT group (57.89%) than in the control group (46.75%) (p=0.006).

Conclusion:

The results suggest that LLLT had a positive effect on the percentage of newly formed bone. Better quality bone sites may allow early removal of the osteogenic distractors, thus shortening total treatment time (AU)
