Clinical Trial Summary

The purpose of this study is to compare the clinical and radiographic effectiveness of Leukocyte-Platelet Rich Fibrin (L-PRF) and L-PRF combined with dental pulp stem cell (DPSC) application to the extraction socket of mandibular third molars.


Description:

Patients aged between 18 and 30 years, seeking for bilateral impacted LM3 extraction surgeries and meeting eligibility criteria were included to the study. At baseline right and left impacted third molars (LM3s) were randomly assigned to one of the treatment group (L-PRF and L-PRF + DPSC). Baseline and 6th month clinical and radiographic measurements were compared.

Procedure:
L-PRF + DPSC
After surgical removal of impacted mandibular third molars, extraction sockets were filled with L-PRF membranes + DPSCs.
L-PRF
After surgical removal of impacted contralateral mandibular third molars, each extraction sockets were only filled with L-PRF membranes.

Outcome

Type Measure Description Time frame Safety issue
Primary Probing pocket Depth (PPD) Probing pocket Depth (PPD) is the distance between gingival margin and bottom of the periodontal pocket in mm. 6 months
Primary Clinical attachment level (CAL) Clinical attachment level (CAL) is the distance between cemento-enamel junction and bottom of the periodontal pocket in mm. 6 months
Secondary Radiographic vertical distance The cementoenamel junction (CEJ) and the most coronal point of the alveolar bone were identified (AC) on the mesial and distal of lower second molars on digital panoramic radiographs. The vertical ruler on each digital image was used to calibrate the image and to convert measurements from pixels to millimeters with ImageJ. The vertical distance (VD) between cemento-enamel junction and alveolar crest of the lower second molar was than measured with "straight line" tool of the software. In order to calculate the real distance; ertical distance was divided to the magnification factor for panoramic image (1.2). 6 months
Secondary Relative bone density (rBD) For every extraction socket, a region of interest (ROI) is created for the socket region and one for the surrounding bone using the "Freehand Selection" tool of ImageJ software on panoramic radiographs. Mean grey values were recorded for each group and relative bone density (rBD) was calculated. 6 months
Secondary Post-operative pain as assessed by visual analogue scale (VAS) Self-reported pain measured in a 100 mm visual analogue scale (VAS) in which (0) denoted "no pain" and 100 meant "severe pain" was recorded at the end of the surgery and 7 days after extraction. 7 days
Secondary Assessment of analgesic usage The patients were asked to note the amount of analgesics within the post-operative 7 days. 7 days
