Treatment outcome in endodontics: the Toronto study phase 4: initial treatment. Its important to take tooth pain seriously. When bacteria are present at the time of obturation, studies show there is an inverse correlation between the quality of obturation and probability of healing. A basic objective of cleaning and shaping a root canal is to allow disinfecting irrigants access to the apical one-third of the root canal. Even though these broad categories exist, endodontic disease is a progression of a single disease one that progresses in a coronal to apical direction over time. If the patient has more sensitivity to horizontal percussion than vertical, and in the absence of other signs or symptoms that would indicate endodontic disease, the issue may be periodontal in origin.26.
