Abstract:
Introduction. Platelet-rich plasma (PRP) is an autologous blood-derived product that
contains a high concentration of platelets in plasma. It is derived from whole
blood by centrifugation. Activated platelets in PRPstimulates bone
regeneration, enhances regenerative processes and postoperative wound
healing, thus simplifying future implant-prosthetic rehabilitation. PRP
promotes re-epithelialization by regulating the biological function of
epidermal stem cells (ESCs) and significantly promotes angiogenesis of
wound tissue. PRP promotes wound contraction and stabilizes the collagen
arrangement.. Because of its simple preparation, high growth factor content
and low immunogenicity, PRP has been widely used in various surgical
operations and clinical treatments and has shown promising experimental
and clinical effects in wound healing.
Purpose. Evaluation of Platelet-rich plasma properties in postextractional
wound regeneration.
Material and methods.
The anamnestic data were collected for a
39-year-old patient, accusing throbbing pain at the level of tooth
3.8. The clinical examination- inspection and palpation and paraclinical
examination-panoramic radiography and VAS test were performed. The
diagnosis and treatment plan were established, as follows: extraction
associated with PRP injection.
The determination of PRP injection efficacy will be performed based on
the following values:
• Facial edema
• Pain / comfort score based on VAS test
•Tissue regeneration.
Results. The study of clinical and paraclinical data of patients indicates that the use of PRF in postextractional wound stimulates bone and tissue regeneration, shortens the
duration of osteogenesis and prevents post-extraction complications.At the
postoperative evaluation of the patient after 7 days of treatment, the intensity of pain
according to the modified VAS method showed decreased values- from 4 to 1, the
postextractional wound was completely healed, the level of regeneration was
attested by the absence of dehiscence, presence of the pale pink epithelium, absence
of the postoperative facial edema according to the craniometric points, the Celsius
signs also were absent.
Conclusions. The angiogenesis and local immune function, so platelets play an important role in hemostasis and healing processes. It greatly enhances reepithelialization, induces
angiogenesis and is also involved in wound contraction and collagen deposition.The
use of PRP biomaterial use of platelet-enriched fibrin autologous biomaterial brings
positive results in improving in wisdom tooth extraction is a minimally invasive
method of tissue regeneration that reduces the rehabilitation period and prevents
the occurrence of post-extraction complications.
