Endodontic treatment of a permanent mandibular first molar and a second molar presumably joined by cementum is presented. This case illustrates the difficulty in interpreting the vitality testing in such a situation. It also suggests possible irreversible pulp injury of a vital healthy tooth caused by extension of the inflammatory periapical pathosis of the adjacent tooth.
