Conditions
Intervention / Treatment
Detailed Description
Design: randomized, parallel and triple blind clinical trial
Sample: Patients with periodontitis (stages III and IV) and positive to Porphyromonas gingivalis who potentially need periodontal surgery were recruited. 25 patients were randomized to the test group (periodontal surgery + azithromycin) and another 25 subjects to the control group (periodontal surgery + metronidazole).
Study visits:
- Examiner calibration
- Recruitment of patients. Screening. Data collection (clinical and microbiological variables).
Phase I.
- Non-surgical periodontal treatment (2 visits).
- Reevaluation at 6 weeks. Data collection (clinical and microbiological variables). Identification of study candidate patients (Patients with probing pocket depth > 5 mm and positive to Porphyromonas gingivalis). Randomization of study groups.
Phase II. Surgical periodontal treatment.
- Periodontal surgery sessions. In the last surgery, the antibiotic test (azithromycin) or metronidazole (control) is administered according to randomization.
- Suture removal 1 week after performing periodontal surgery. Data collection 1 week after antibiotic consumption with the last surgery (patient-centered variables on the side effects of antibiotics).
- Re-evaluation of the surgical phase at 6 weeks after the last surgery session. Data collection (clinical variables).
Phase III. Periodontal maintenance.
- Maintenance 1 (3 months post surgery). Data collection (Clinical and microbiological variables).
- Maintenance 2 (6 months post surgery). Data collection (Clinical and microbiological variables).
- Maintenance 3 (9 months post surgery). Data collection (Clinical variables).
- Maintenance 4 (12 months post surgery). Data collection (Clinical and microbiological variables).
- Maintenance 5 (4 years post surgery). Data collection (Clinical and microbiological variables).
