Title: Effect of Three Periodontal Therapies in Current Smokers and Non-Smokers
Brief Summary: The purpose of this study is to determine in current and non-smokers the clinical and microbiological effects of 3 therapies: scaling and root planing (SRP) alone; SRP in combination with the orally administered antibiotic metronidazole; and SRP with the orally administered antibiotics metronidazole and amoxicillin along with the locally delivered antibiotic doxycycline at periodontal pockets \>= 4 mm.
