Title The Adjunct Use of Azithromycin with Nonsurgical Periodontal Therapy Produces Probing Depth Reductions Similar to Metronidazole-Amoxicillin in Patients with Generalized Aggressive Periodontitis
Clinical Question For patients with generalized aggressive periodontitis treated with nonsurgical periodontal therapy, will the use of adjunct systemic azithromycin compared to the use of metronidazole-amoxicillin in combination result in greater probing depth reduction?
Clinical Bottom Line For patients with generalized aggressive periodontitis, nonsurgical periodontal therapy treatment in conjunction with systemic azithromycin produced similar probing depth reduction as metronidazole-amoxicillin and greater probing depth reduction compared to nonsurgical periodontal therapy without systemic antibiotic use.

#1) 25966723Ercan/201545 patients -15: SCRP alone (Control) -15: SCRP + azithromycin - 15 SCRP + metronidazole & amoxicillin (M + A)Controlled Trial
Key resultsAll 3 groups of patients experienced probing depth reduction, but patients in the experimental groups showed greater probing depth reduction than patients in the control group (SCRP + azithromycin: -1.29 ± 1.39, SCRP + (M+A): -1.27 ± 0.51, control -0.79 ± 0.55). However, these differences were not statistically significant.

The Evidence
Validity: The sample size of this randomized controlled trial was small with a short follow-up time. Additionally, no immunological or microbiological parameters were considered in this study model. The experimental and control groups were similar in terms of age, gender and clinical parameters.
Applicability This information can benefit clinicians considering the use of systemic antibiotics as an adjunct to nonsurgical periodontal therapy. Patients prescribed azithromycin may be more compliant in following the antibiotic regimen because it is often easier to follow (AZT 500mg tablet once day for 3 days vs. M+A 500mg each 3 times/day).
