Evaluation of the therapeutic effects of Er:YAG laser with different parameters on peri-implantitis

This study evaluates the therapeutic effects of erbium-doped yttrium aluminum garnet (Er:YAG) laser treatment at different energy settings on peri-implantitis in a randomized clinical setting. Forty patients diagnosed with permanent molar fissure caries were randomly assigned to 5 treatment groups, each receiving a distinct treatment protocol. The effectiveness of these interventions was evaluated by comparing restoration dislodgement rates, caries recurrence, and patient-reported oral comfort. Treatment groups subjected to higher energy settings (60 mJ and 80 mJ) of Er:YAG laser exhibited significant reductions in PD and bleeding index compared to the control group. The 80 mJ group demonstrated the most notable improvements, including the lowest PD and bleeding index values and the greatest reduction in postoperative pain. In contrast, the control group showed only marginal changes, with no significant variations in plaque index or pain levels. Er:YAG laser therapy, particularly at higher energy levels (80 mJ), enhances clinical outcomes in peri-implantitis treatment by effectively reducing plaque biofilm, inflammation, and pain. These findings underscore the importance of optimizing laser energy parameters for improved peri-implantitis management.
