Vital Root Amputation in Molars With Advanced Periodontal Furcation Involvement: a Preliminary Study

The goal of this clinical trial is to test in 10 patients with advanced furcation involvement on molars. The main question[s] it aims to answer are:• Is it possible to carry out root resection without endodontic treatment on molars? Tooth vitality will be checked (positive response to cold test). Root resection will be carried out under local anestesia.Following visits will be carried out for re-evaluation/maintenance according to clinical care every 3 mounths until 3 years follow-up.
