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

Study Overview
=================
Brief Summary
-----------------
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Patients with advanced periodontal furcation involvement<br> | Procedure: root resection<br>* It will be carried out under local anestesia. Intra-crevicular or para-marginal gingival incision will be carried out and full-tickness mucoperiostal flaps will be raised to expose the affected roots. Whit the use (if possible) of a surgical stent an incision will be performed on the root to be removed. Biodentine will be used for retrogade obturation. The flaps will be sutured.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Tooth vitality (positive response to cold test) | following the 3rd visit will be make a re-evaluation of the tooth vitality, by a positive response to cold test, every 3 month. | 3-year follow-up | 
| No periapical lesion | following the 3rd visit will be make a re-evaluation of the periapical heath condition, by a periapical rx, every year | 3-year follow-up |
