Periodontal implications of argyrophilic nucleolar organizer region: A mini reviewPeriodontal implications of argyrophilic nucleolar organizer region: A mini review

The periodontal lesions with cellular proliferation can be assessed by various methods. One of the methods to determine the proliferative activity is silver-staining argyrophilic nucleolar organizer region (AgNOR) staining. AgNOR can be used as diagnostic and prognostic tool for many of periodontal lesions which are proliferative in nature and may be quantitative marker of incipient cellular alterations before the histologic hallmarks appear. Hence, this paper reviewed about the periodontal applications of AgNOR staining
