Clinical Trial Summary

Primary purpose: Evaluate the effect of azithromycin on failure proportion of severe chronic periodontitis non-surgical treatment; failure characterized by the persistence of at least one periodontal pocket> 5mm at 6 months Secondary purpose: - Evaluate the effect of azithromycin on the persistence of pathological periodontal pockets > 5mm during non-surgical treatment of severe chronic periodontitis at 3 months and 6 months - Evaluate the effect of azithromycin on the changes of clinical signs, periopathogen levels, expression of macrolides resistance genes, and expression of antimicrobial peptides (PAMs) during treatment of severe chronic periodontitis at 3 months and 6 months - Assess therapeutic observance and side effects of antibiotic treatment - Assess at 3 and 6 months the potential interactions of local, bacterial (periopathogen and resistance gene) clinical factors, and host defense (PAMs) with the effect of azithromycin, on failure proportion of severe chronic periodontitis non-surgical treatment
