Figure 7: Clinical view at 15-year follow-up: The second molar was prosthetically treated with a zirconia crown and the distal rest of the first molar was removed. The palatal radisected root and its crown are still in place, with neither pathological pocket probing depth (<4 mm) nor lack of inflammation, pale and pink buccal tissues, and well-keratinized interdental tissues. Probably due to the distal rest removal, slight tooth mobility was present
