Peridontal prognosis refers to the prediction of outcome or future of the tooth once the periodontal disease sets in. The primary goal of periodontal therapy is the long term retention of teeth in a state that is healthy, painless, esthetically pleasing and functional. At the end of active therapy, the tooth could be lost or could still survive and be stable. Survival of the teeth depends on several local and general factors. Considering that periodontal disease is episodic, observation of stability is dynamic and must be evaluated periodically. When, then, should a periodontally involved tooth should be kept?
