Aims To compare a monotherapy of Er:YAG laser debridement (ERL), wavelength 2940 nm, with mechanical scaling and root planing (SRP) for the treatment of chronic periodontitis using clinical and patient-centred outcomes. Methods Twenty-eight participants had two randomly assigned quadrants treated with ERL and two with SRP. Full-mouth plaque index, probing depth, bleeding on probing, clinical attachment level and gingival recession were recorded at baseline and 6- and 12-weeks post therapy. A questionnaire was used to assess pain, discomfort and satisfaction during and after treatment. Results Twenty-two participants completed treatment and had 6- and 12-week clinical re-evaluations. SRP provided greater mean pocket depth reduction at 6- and 12-weeks (p similar to 0.01 and p similar to 0.003 respectively), and a greater reduction in pockets similar to 4 similar to mm at 6 similar to weeks only (p similar to 0.03) compared with ERL. SRP also resulted in a significant reduction in bleeding on probing (BOP) sites at 12 similar to weeks compared with ERL and a statistically significant greater reduction in mean clinical attachment level (CAL) at 6- (p similar to 0.02) and 12-weeks (p similar to 0.03). Patients expressed greater satisfaction with SRP on the day of treatment but were equally satisfied subsequently. Conclusion SRP resulted in a statistically significant greater short-term improvement in clinical parameters and patient satisfaction compared with ERL.
