The prognosis for a cracked tooth following endodontic treatment can be guarded depending on several factors. Factors affecting the prognosis of a cracked tooth after endodontic treatment are not well known and there is limited evidence upon which to make treatment recommendations. The purpose of this study was to determine the factors that most influence practicing endodontists in their decision to provide endodontic treatment or recommend extraction of a cracked tooth. An invitation for a questionnaire on Survey Monkey was sent via email to 4,110 active and international members of the American Association of Endodontists. Respondents were given multiple hypothetical scenarios and asked to assess how these different situations would affect their decision to treat or extract a cracked mandibular molar. Odds ratio, chi-squared, and ANOVA were used to evaluate the data. A total of 523 individuals completed the questionnaire for a response rate of 12.7%. On a scale of 1-5 in significance, periodontal probing depths adjacent to the crack (96%), apical extent of the crack (91%), and presence/absence of lateral or furcal radiolucency (80%) were rated as the most significant clinical factors in the respondents’ decision followed by need for a post (44%) (p<.0001). In conclusion, better evidence is needed to assist endodontists in the decision to treat or extract a tooth diagnosed with a crack. Periodontal probing depths adjacent to the fracture and apical extent of the crack clinically appeared to be most influential in the clinical treatment decision.
