This was a challenging case with the combined issues of a failed root canal therapy and an iatrogenic perforation of the floor of the pulp chamber. Though initially the prognosis could not be evaluated effectively simply because of non-availability of peer-reviewed literature of similar cases for citation, but the case was taken on owing to the patient’s desire to salvage the natural tooth. The importance of magnification and the ergonomic use of the dental operating microscope cannot be more clearly demonstrated than in this case.

The success of any endodontic therapy depends on adequate chemical and mechanical debridement of the infected root canal. This requires basic knowledge of the canal anatomy and the ability to identify any aberration in it. Studies have shown that micro-organisms in the root canal system reside in the main canal, the canal’s ramification, the accessory or lateral root canal, and even the dentinal tubules. Therefore, optimal debridement can only be achieved if the clinician is able to identify the presence of additional canals prior to or during treatment (Table 1).

Root-canal treatment has been shown to have a success rate of 92%. However, as research methodologies move towards higher levels of substantiation, clinicians must rely on the best current evidence available to gain insight into the expected outcomes of their treatment. The highest level and best current evidence we have on the clinical success of endodontic treatment comes from a meta-analysis of the literature.
