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

Patient following or having followed a drug treatment (cyclosporine and other anti-rejection drugs, antiepileptic, calcium inhibitor) influencing periodontal status
Patient with pathologies influencing periodontal status and/or systemic or local inflammatory response, such as diabetes, infectious stomatitis or not, diseases inflammatory and autoimmune, immuno-depression
Patient with prolonged oral hygiene disability (physical/psychic impossibility of brushing teeth)
Patient with impaired oral condition (untreated cavities, non-dental teeth rehabilitated), dental infections whose management requires antibiotic treatment within 6 months
Patient having specialized periodontal treatment, root planning, or a periodontal surgical treatment in the year prior to the examination
Pregnant woman or breastfeeding
Patient with repeated chronic infections (more than 3 times per year) requiring antibiotic treatment
Patient who had oral antiseptic treatment in the previous month
Patient included in another intervention research protocol or in periods of exclusion (participation in an observational study remains possible)
