Use of 5-Nitroimidazole drugs in the treatment of periodontitis

open access: yes, 2014
Periodontal disease, a common cause of tooth loss, is an inflammatory response to the overgrowth of anaerobic and micro-aerophilic organisms in the subgingival plaque. Various 5-Nitroimidazole chemotherapeutic agents have been discussed in this review article with a special emphasis on periodontal gels because of their relatively fast rate of drug ...
