TwinLight® Protocol and AutoSWEEPS Photoacoustic Irrigation for Periodontal Treatment – Split Mouth Case Report

Periodontal diseases remain a major challenge in modern dentistry, affecting the supporting tissues of teeth and implants.

The TwinLight® laser protocol has shown strong clinical efficacy, and recent evidence suggests that cavitation-based methods may further enhance outcomes. This case report compares the standard TwinLight® protocol to a modified approach incorporating AutoSWEEPS photoacoustic irrigation. Both sides of the mouth received identical Nd:YAG laser steps, while the left side used Er:YAG AutoSWEEPS irrigation instead of MSP direct ablation.

Results showed a reduction in the number of sites with probing depths ≥4 mm from 39 sites to 1 site and a drop in bleeding on probing from 72% to 11%, with better outcomes on the AutoSWEEPS-treated side. These findings support the added benefit of photoacoustic cavitation in periodontal therapy.

Key words: Periodontal treatment TwinLight® SWEEPS.
