Comparison of the effect of albumin with platelet-rich fibrin (Alb-PRF) gel and hyaluronic acid gel injection on interdental papilla reconstruction: A randomized clinical trial.

Background: The interdental papilla plays a crucial role in the esthetic of the smile. Papilla reconstruction surgery is one of the most unpredictable periodontal procedures. This study compared the effect of the non-surgical application of a commercial hyaluronic acid (HA) gel with an autogenous gel named "albumin with platelet-rich fibrin" (Alb-PRF) on interdental papilla reconstruction.

Multiple Mental Foramina: A Rare Anatomical Variation Detected by Cone-Beam Computed Tomography (CBCT).

The mental foramen is a single anatomical structure that can be seen bilaterally in the body of the mandible and generally in the lower area of the premolars. Sometimes, the mental foramen can have accessory foramina that should be considered. Clinical evaluation of the accessory mental foramina is critical because of its neurovascular fibers.

Comparative Evaluation of the Effect of Two Platelet Concentrates (a-PRF and L-PRF) on the Cellular Activity of Pre-osteoblastic MG-63 Cell Line: An in vitro Study.

Statement Of The Problem: Currently, the reconstruction of bone defects with new platelet concentrates is considered a significant challenge in periodontics.

Purpose: This study aimed to evaluate advanced- platelet rich fibrin (A-PRF) and leukocyte- and platelet rich fibrin's (L-PRF) effects on the proliferation and differentiation of MG-63 cells.

Materials And Method: In this study, blood samples of five healthy non-smoking volunteers were collected and immediately centrifuged according to the two protocols of Choukroun and Ghanaati, without adding any anticoagulants, to prepare L-PRF and A-PRF.
