Descrizione dettagliata
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.

Armi e interventi
Gruppo di partecipanti / Arm |
Intervento / Trattamento |
|---|---|
|
Sperimentale: PRF (platelet-rich fibrin)
PRF will be used after the extraction of the third molar to prevent periodontal defects to second molar
|
After loco-regional anesthesia was administered, a full-thickness mucoperiosteal flap was raised.
The flap incision was extended from the vestibular side of the retromolar trigon to the second molar, corresponding to its distolingual cusp.
The incision continued intrasulcular at the second molar and proceeded with a release incision distally to the papilla between the first and second molars, on a 45° angle.
An osteotomy using a Lindemann burr under constant irrigation, followed by an odontotomy using a diamond burr was performed, if necessary

Comparatore attivo: spontaneous healing
after the extraction of the third molar the socket will be left to heal spontaneously

|
Clinical attachment level change
Lasso di tempo: 12 and 18 weeks
|
the clinical attachment level is the distance between the gingival margin to the cemento-enamel junction. the measurement is made by using a Williams periodontal probe. Differences in changes are measured from baseline to 12 and 18 weeks. |

probing depth change
Lasso di tempo: 12 and 18 weeks
|
The probing depth is the distance from the free end of the gingival margin to the bottom of the periodontal pocket.
The measurement is made by using a Williams periodontal probe.
Differences in changes are measured from baseline to 12 and 18 weeks.

gingival recession change
Lasso di tempo: 12 and 18 weeks
|
The distance between the cemento-enamel junction and gingival margin gives the level of recession. The measurement is made by using a Williams periodontal probe. Differences in changes are measured from baseline to 12 and 18 weeks. |
