This study aims to know the effect of PRP on bone healing and regeneration after cystoectomy within studying clinical and radiological bone density changes. The research sample comprised 18 patients (14 males, 4 females) (20 cystic lesions in the upp
er jaw,1-3 cm diameter). This sample was divided into 2 similar groups :
The experimental group: Platelets-rich Plasma with Tri-Calcium Phosphate was applied.
The control group: only Tri-Calcium Phosphate, without Platelets-rich Plasma, was applied.
Both groups were observed clinically and radiologically. According to radiological observation, the digital panoramic radiographs were taken before, immediately after surgery, after 3 months, and after 6 months, respectively. Bone density measurements were done through Digora® digital program.
The present study showed that there is no statistical difference between the experimental group & the control group, regarding Pain Index and Infection Index; while there was a statistical difference between the experimental group & the control group, regarding bone density after 3 and 6 months after surgery.
Within the limitations of the present study, the application of autologous platelets-rich plasma (PRP) accelerates bone regeneration after cystoectomy.
The study aimed to Compare the effect of combination Platelet Rich
Plasma with bovine derived xenograft and bovine derived xenograft
alone in treatment of human class II furcation defects in mandibular
molars. Twenty systemically healthy patients,
aged 32 to 58 years with
chronic periodontitis participated in the study . Each patient had 2 buccal
mandibular class II furcation defects (first or second molars) were
randomizely treated either with : bovine – derived xenograft with
Platelet – Rich plasma, or with bovine - derived xenograft alone.
The aim of this study is to evaluate the clinical outcomes (pain P ,
joint sounds JS , and diversion in the mandibular movement DMM)
of treatment of anterior displacement of articular disc via injection of
PRP. The sample consisted of 40 patients
who referred to the faculty
of dentistry with unilateral anterior displacement of articular disc
with pain P , joint sounds JS , and diversion in the mandibular
movement DMM.
This study is aimed to evaluate the role of Platelet Rich Plasma PRP on osteogensis
in periosteal distraction. The sample consisted of 12 rabbits from local spices. The sample
divided equally into two groups, titanium mesh with holes was used in to
elevate the
periosteum and the space between the surface of bone and the mesh was filled with
collagen sponge, in the test group the sponge was injected with PRP. The rabbits were
killed after eight weeks after operation and the samples were prepared for histological
study. The histological study of specimens of control group showed formation of small
island of osteoid with large areas of connective tissue. While, in test group there was an
increasing in bone formation in form of wide area of woven bone and decreasing in
connective tissue. We conclude that application of Platelet Rich Plasma PRP lead to
improvement in bone formation in periosteal distraction.
The aim of this study is to evaluate the clinical outcomes of
treatment of temporomandibular joint disorders via injection HA &
PRP. The sample consisted of 24 patients with TMD.
