Root morphology--clinical significance in pathogenesis and treatment of periodontal disease.

Root morphology is a seldom considered yet extremely important factor in the treatment of periodontal disease. The shape of the roots may contribute to development of periodontal defects by providing an environment favorable to the retention of plaque. The practitioner should periodically review root morphology and give it appropriate importance during planning and treatment. In this study, teeth with representative root anatomy were sectioned and photographed. The photographs are intended as a visual presentation of various root morphologies and their potential implications in the practice of periodontics.
