Clinical and Microbiological Evaluation of Laser Therapy in the Treatment of Periodontal Disease in Stages III and IV

Conventional periodontal treatment, scaling and root planning, will be performed with ultrasound (Dabi Atlante, Rio de Janeiro, RJ, Brazil) complemented with Gracey curettes (Golgran, São Caetano do Sul, SP, Brazil) on each patient under local anesthesia. The maintenance therapy will include professional plaque control and scaling and root planning in recurrent periodontal pockets, every 30 days, until 3 months, when the periodontal parameters will be reassessed.
