Hou and Tsai introduced a grading system for IBRs using an electronic digital caliper to calculate dimensions as less than 1 × 1 mm, between 1 × 1 mm and 2 × 2 mm, and 2 × 2 mm or greater as Grades I, II, and III, respectively.⁵⁵ It is important to bear in mind that when IBRs are present in furcation defects, these may predispose to further attachment loss by hindering the patient’s plaque control and the clinician’s ability for proper mechanical instrumentation during active and/or supportive therapy.
