Prevention of Mandibular Third Molar Extraction- Associated Periodontal

Status Completed

Clinical Trial Summary

The extraction of deep impacted mandibular third molar may cause periodontal defects at the distal root of the second molar. The aim of this study was to evaluate the ability of platelet-rich fibrin (PRF) in preventing periodontal complications at the distal root of the second molar adjacent to the extracted third molar.

Clinical Trial Description

Eighteen young patients with bilateral impacted mandibular third molars will be selected. All 36 cases of impactions will be selected for a split mouth study and randomly treated by using 2 different therapeutic approaches, thereby yielding 2 different study groups, each of which is composed of 18 cases: in one side the post-extraction socket is left healing spontaneously, on the other side the socket is filled with PRF.

CAL at the distal surface of the lower second molar is chosen as primary outcome.

Criteria will be the presence of a pocket distal to the mandibular second molar with a probing depth >7 mm and a probing clinical attachment level >6mm.

This study was designed as a single-blind research since subjects will be unaware of their treatment allocation. A software will be used to produce a random sequence of 18 integer numbers without duplicates generated from atmospheric noise and concealed in closed envelopes by one of the investigators. At the time of the patient's first surgery, the envelope will be opened and patient allocated either to group 1 (PRF on the right side, spontaneous healing on the left side), for allocation numbers 1-9, or group 2 (spontaneous healing on the right side, PRF on the left side), for allocation numbers 10-18.

One clinician, not involved in patient treatment and not aware of what therapeutic approach used for the different sites of treatment, will perform all clinical measurements (PD, CAL, gingival recession, plaque index and gingival bleeding index) before and after 12 and 18 weeks of surgery.

Clinical and radiographical measurements will be recorded at 12 and 18 weeks after the surgery. The Student t test will be used to compare the differences between the 2 groups. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
