Effect of Vitamin D Deficiency on the Structure of Titanium Platelet-Rich Fibrin

Not Applicable

Completed

• Conditions: PRF; Vitamin D Deficiency; Vitamin Deficiency

• Registration Number: NCT06870786
• Lead Sponsor: Abant Izzet Baysal University

Brief Summary

ABSTRACT The aim of the study was to compare the macroscopic properties, chemical degradation levels, and fibrin network structures of T-PRF membranes obtained from systemically healthy individuals with optimal vitamin D levels, with vitamin D-deficient individuals who reached optimal levels after three months of vitamin D supplementation.

A total of 48 participants, 24 with vitamin D deficiency and 24 with optimal vitamin D levels, were included in the study. The macroscopic properties (weight, width, length, density), chemical degradation levels and fibrin network structures of the obtained T-PRF membranes were evaluated using scanning electron microscopy (SEM) and light microscopy.

Detailed Description

Blood samples taken from individuals with the help of a 20 ml syringe were immediately transferred to 2 10 ml titanium tubes and placed opposite each other to ensure balance in the tabletop centrifuge device in order to be properly separated in the centrifuge process. To obtain T-PRF, it was centrifuged in the IntraSpin™ device at 2700 rpm centrifugal force for 12 minutes.

After centrifugation, the fibrin in the middle of the 3 layers formed in the titanium tube was held and pulled with the help of a press. Then, the red layer in the lower layer, where erythrocytes were dense, was separated from the fibrin layer with the help of scissors and the membrane was obtained by pressing for 2 minutes using the own weight of the PRF box.

Primary Outcome Measures

Name	Time	Method
microscopic analysis	From enrollment to the end of treatment at 3 months	T-PRF membranes were examined histologically using the cell block cytology method. Membranes were transferred to cassettes and fixed in formalin solution for 24 hours. At the end of 24 hours, the cassettes were subjected to dehydration with various concentrations of formalin, alcohol and xylene. The tissue was embedded in Leucher blocks using paraffin so that it could be easily cut and examined. 3 µm thick sections were taken from the embedded blocks using a microtome. Paraffin in the blocks was removed and the tissue was stained with hematoxylin-eosin L-PRF clot was analyzed microscopically on hematoxylin-eosin stained slides using the blood element adhesion index score 0: absence of fibrin network score 1: sparsely dispersed fibrin network score 2: thin fibrin network poorly interlocking score 3: dense fibrin network abundantly interconnected

Secondary Outcome Measures

Name	Time	Method
Scanning Electron Microscope (SEM) Examination	From enrollment to the end of treatment at 3 months	In order to visualize the surfaces of the samples, they were coated with 20 nm gold/palladium sputtering and photographs were taken and recorded under different magnifications.
T-PRF Degradation of Membranes	From enrollment to the end of treatment at 3 months	T-PRF membranes weighed was placed in an orbital shaking device in 7.4% PBS solution for 1 week in order to evaluate the degradation rates Degradation amounts were calculated as:% degradation=(initial weight-final weight)/initial weight x 100
