Abstract:

Objectives: 1. Speed of removing pigmentation from the pigmented tissues that was measured by a stop watch 2. Controllability of stopping applying the laser when desired, that was measured by numbers 3. Amount of carbonized area 4. The best power setting for depigmentation depending on the results of the previous four objectives 5. Pain 6. Bleeding 7. Healing Materials and Methods: Four pulse durations VLP, LP, SP, and MSP ?that already exist in the AT FidalisFotona laser machine? were the basic for applying six power settings measured by J/cm2 for each pulse duration in the animal study. Choosing of the power settings depended on trying the lowest setting available in the laser machine and increasing the power gradually up to 6J/cm2 ?below the ablation threshold of dentin, cementum and enamel. The animal is a sheep sacrificed less than 6 hours before the experiment. As a result, four power settings were suggested to be applied on human. Then, they were studied. Results: The objective were answered by tables include numbers and cumulative results were concluded. Conclusion: It seems that power settings range from 2J/cm2 to 4J/cm2 for VLP, LP, and SP are suitable to use in humans, considering some differences between them.
