Endodontic Disease
Conditions
Brief summary
This study was conducted to evaluate clinical and radiographical outcome of using a standardized platelet-rich plasma (PRP) biomembrane following endodontic surgery and its correlation with the growth factors content in this concentrate.
Detailed description
15 healthy patients of both genders, between 20 and 45 years of age, presenting with 22 anterior/premolar teeth in need of endodontic surgery were recruited. Teeth presented with failed non-surgical root canal therapy and periapical radiolucency of ≥ 1cm in size. Patients were randomly divided following surgery into two groups, with 11 teeth each.
Interventions
PROCEDUREosteotomy filled with PRP-gel and covered with PRP-biomembrane
PROCEDUREosteotomy site following the surgical intervention was left empty

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| degree of periapical inflammation using periapical index (PAI) | baseline | The PAI is a 5-point scale radiographic interpretation designed to determine the absence, presence, or transformation of a disease state. Each of the roots was categorized as: (1) Normal periapical structure; (2) small changes in bone structure; (3) changes in bone structure with some mineral loss; (4) periodontitis with well-defined radiolucent area; and (5) severe periodontitis with exacerbating features. Each category used in the PAI represents a step on an ordinal scale of registration of periapical infection. |
| degree of periapical inflammation using CBCT periapical index (CBCTPAI) | baseline | CBCTPAI is a 6-point (0 -5) scoring system .The scores were calculated by analysis of the lesion in 3 dimensions, with CT slices being obtained in mesiodistal, buccopalatal, and diagonal directions. The score was determined by the largest extension of the lesion. The measurement of lesion depth in a CBCT image added the variables expansion of cortical bone (E) and destruction of cortical bone (D) usually detected starting from score 2. |
| changes in bone mineral density of lesions in CBCT images | baseline | region of interest measurements were made by the same operator in the sagittal view to provide consistency throughout the study protocol (baseline and at a 12 to 18 months post-operative interval). ROI was selected through drawing a polyline pattern that enabled us to include all the confines of the lesion (On Demand 3D® viewing software was used to obtain a mean grey level using the region of interest (ROI) polyline tool in sagittal plane images. The images of each CBCT scan were captured using the print screen button and exported into a Microsoft Word document as a record. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| concentration of Platelet-derived growth factor (PDGF) in the prepared PRP | baseline | concentration of Platelet-derived growth factor (PDGF) in the prepared PRP was quantified using ELISA methods (R&D Center, Tokyo, Japan). The analyses were then performed as instructed by manufacturer |
| concentration of vascular endothelial growth factors (VEGF) in the prepared PRP | baseline | Concentrations of VEGF growth factors in PRP was quantified using ELISA methods (R&D Center, Tokyo, Japan). The analyses were then performed as instructed by manufacturer |
| Platelet count in whole blood sample and in platelet rich plasma concentrate | baseline | Platelet count in whole blood sample and in platelet rich plasma concentrate is assessed to detect fold increase in platelet count |
