Clinical Trial Summary

Will the addition of vitamin A (Retinol) to PRF add more periodontal regenerative value in the treatment of intra-bony defects compared to PRF alone, clinically?


Clinical Trial Description

Vitamin A has been extensively studied for its role in bone health. Vitamin A can be consumed in two forms, i.e., preformed retinol and pro-vitamin A. Preformed retinol is often found in food originated from animals, such as dairy, liver and eggs. Provitamin A, such as alpha (α)-carotene, beta (β)-carotene orβ-cryptoxanthin, are commonly found in plant-based food, such as fruits and vegetables (Toti et al., 2018). At certain concentrations, it has been proven to enhance the pluripotency of periodontal cells for regeneration (Fawzy El-Sayed, Hein and Dörfer, 2019). Yet, to the best of our knowledge no clinical trials have evaluated the effect of Vitamin A added to PRF in the regeneration of intra-bony defects. This study is to fill the gap of knowledge. ;
