Abstract : Purpose: The experiment was conducted to evaluate the effect of the application of low-intensity laser irradiation on the healing of distracted dog's mandibles after distraction osteogenesis was applied without a latency period. Material and Method: Eight healthy adult mongrel dogs were used and were subdivided into two C{jualgroups (A & B) that underwent distraction osteogenesis at a rate of I mm/day in two 12 hourly increments of 0.5 mm each for a period of ten days. Group A animals received 3 minutes of lowintensity laser irradiation on allernme days for the ten day period of distraction as well as for four weeks of consolidation. Group B animals received the same protocol of distraction but no laser irradiation. One animal from each group was excluded because of spontaneous premature loss of the distraction device. The animals were humanely kilIed after six weeks from the start of the experiment. Their mandibles were dissecte'd free and each half mandible was measured. examined macroscopicaUy and the distraction areas were prepared for H.&E. histologic examination. ResultS: The operated upon right sides of the mandibles were longer than the unoperated Idt sides by an average of 8.566 mm in the laser-irradiated animals and 1!.5mm in the non-irradiated animals. with resulting deviation of the midline towards the unopermed side. Histologic examination revealed bone healing in both groups. with more advanced healing and bone remodeling in the laserirradiated group. Cociusions: There was no distinct different:e in the stability of distrat:tion when no lment period was allowed in both low-intensity laser irradiated and non-laser irradiated groU)Js. Low-intensity laser irradiation following distraction with no latenl period. however. manifestly cnt'ouraged :1nd :1Ct: elerated bone healing and remodeling.
