NCT03132714

Brief Summary

The aim of this project is to compare the efficacy and the local effect of the association of single or repeated application of photodynamic therapy (PDT) with antibiotic agents using Amoxicillin + Metronidazole or Clarithromycin in the treatment of patients with Generalized Aggressive Periodontitis (GAgP).
