Title: Impact of Different Dosages and Time of Administration of Metronidazole and Amoxicillin in the Treatment of Generalized Chronic Periodontitis: A Randomized Clinical Trial
Brief Summary: The aim of this study was to compare the clinical and microbiological outcomes of different dosages of metronidazole (MTZ) and of the duration of the systemic administration of MTZ and amoxicillin as adjunct to scaling and root planing (SRP) in the treatment of generalized chronic periodontitis (GChP).
