Abstract: Bicuspidization is a surgical procedure performed on the mandibular molars for the separation of the mesial and distal roots with their respective crown portions; this separation eliminates the existence of a furcation and facilitates effective oral hygiene practice. This case report aims at highlighting the conservative management of a grade III furcation-involved molar by bicuspidisation procedure and use of the treated tooth as an abutment for fixed prosthesis.
