Abstract
Platelets contain a multitude of growth factors and play a crucial role in physiological processes such as thrombogenesis, tissue repair, and angiogenesis. As a result, platelet-derived products have significant potential for efficient utilization in the realm of regenerative medicine due to their therapeutic and biological attributes. Numerous studies have already substantiated the therapeutic viability of platelets in various canine ailments. The existing literature indicates a substantial surge in the clinical application of canine platelets, positioning platelet-derived products as a viable alternative to conventional therapeutic agents. Platelet concentrates, including platelet-rich plasma and platelet-rich fibrin are commonly used as a therapeutic modality in clinical cases. These therapeutic derivatives exhibit effectiveness in tissue regeneration and can serve as complementary therapies. Notably, they offer a cost-effective and easily accessible therapeutic option, which has demonstrated its benefits in chronic inflammatory disorders such as osteoarthritis and tendinitis, ophthalmic conditions, wound healing, and mandibular injuries in canine patients. The broad spectrum of therapeutic effects displayed by platelets is providing researchers with novel perspectives for crafting therapeutic models in future investigations. This review centers on exploring the therapeutic potential of canine platelets across diverse disorders. Further exploration into platelet products, encompassing their preparation and applicability in canine medicine, is imperative. These inquiries hold the promise of unveiling fresh horizons for the domain of regenerative medicine.

Comparative histological evaluation of two PRF formulations (PRF High and PRF Medium) on quality of life and healing outcome of apicomarginal defects: A randomized clinical trial. J Craniomaxillofac Surg 2023; 51:166-177. [PMID: 36894343 DOI: 10.1016/j.jcms.2023.02.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 01/28/2023] [Accepted: 02/15/2023] [Indexed: 02/25/2023] Open
Abstract
The objective of this randomized clinical trial was to investigate the effects of two PRF formulations (PRF High and PRF Medium) on quality of life and healing outcome (2D and 3D) of apicomarginal defects. Patients presenting with endodontic lesions and concomitant periodontal communication were randomly allocated to PRF High and PRF Medium groups. The treatment protocol in each group included a periapical surgical procedure with placement of PRF clot and membrane in the bony defect and on the denuded root surface, respectively. Quality of life was assessed for 1 week after surgery following a modified version of the patient's perception questionnaire. Postoperative pain was assessed using a visual analog scale. Clinical and radiographic evaluations were performed using Rud and Molven 2D criteria and Modified PENN 3D criteria. Buccal bone formation was assessed using sagittal and corresponding axial sections in CBCT. Histological analysis was performed using hematoxylin and eosin (H and E) staining and attaching primary antibodies to tissue sections. In total, 40 patients were enrolled in the trial (N = 20 per group). PRF Medium group patients reported significantly less swelling on the 1st (p = 0.036), 2nd (p = 0.034), and 3rd (p = 0.023) days, and average pain on the 2nd (p = 0.031), 3rd (p = 0.03), and 4th (p = 0.04) days postoperatively. The difference in success rate for periapical healing was non-significant between the PRF Medium group (89.5%) and PRF High group (90%), in both 2D and 3D imaging (p = 0.957). The formation of buccal bone was observed in five cases (26.3%) and four cases (20%) in the PRF Medium and PRF High groups, respectively, with a non-significant difference (p = 0.575). PRF Medium clots had a loose fibrin structure with a significantly higher number of neutrophils (473.79 ± 82.89 per mm2) than PRF High clots, which had a dense structure and fewer neutrophils (253.15 ± 63.86 per mm2) (p = 0.001). Autologous platelet concentrates (APCs) promoted satisfactory periapical healing, with no significant difference between the groups. Within the limitations of the study, it seems that PRF Medium should be preferred over PRF High when the patients' quality of life is the priority.

Abstract
INTRODUCTION Endodontic microsurgery is a treatment of last resort for preserving natural teeth. According to radiographic evaluation, the percentage of complete healing after endodontic microsurgery is only 74.3%. The use of regenerative techniques in endodontic microsurgery for large lesions (>10 mm diameter) is therefore recommended. The most frequently used bone graft in endodontic microsurgery is anorganic bovine bone mineral (ABBM) but this only has an osteoconductive effect. Thus, when platelet-rich fibrin (PRF), a reservoir of growth factors, is used together with ABBM, it increases the regenerative effect. This study is devoted to comparing the clinical outcomes of PRF with/without ABBM as grafting biomaterials in endodontic microsurgery cases with large lesion size to provide some valuable reference data for dentists. METHODS AND ANALYSIS Sixteen patients who are in need of endodontic microsurgery will be recruited. The patients will be randomly assigned to one of two groups: an experimental group, treated with PRF/ABBM complex and collagen membrane, and a control group, treated with ABBM and collagen membrane. Clinical examination including percussion, mobility testing and presence/absence of sinus will be recorded at 7 days, and at 3, 6 and 12 months after endodontic microsurgery. A Visual Analogue Scale will be used by the patients to evaluate pain at 1, 3 and 7 days after endodontic microsurgery. Routine paralleling radiographs will be obtained before and at 3, 6 and 12 months follow-up after endodontic microsurgery. Cone-beam CT (CBCT) scans will be obtained at the 12-month follow-up. Bone formation will be evaluated according to CBCT and paralleling radiographs. The study execute time including follow-ups last from 1 June 2021 to 31 December 2024. ETHICS AND DISSEMINATION This study received approval from the Ethics Committee of Peking University School and Hospital of Stomatology. The results will be disseminated through scientific journals. TRIAL REGISTRATION NUMBER Research data will be registered with the International Clinical Trials Registry Platform (ICTRP), ID: ChiCTR2100046684.

Abstract
Platelet concentrates have been widely used in regenerative medicine, including endodontics. The aim of this manuscript was to assess critically the efficacy of PRF in the treatment of endodontic periapical lesions in adult patients on the basis of the literature. The PICO approach was used to properly develop literature search strategies. The PubMed database was analyzed with the keywords: "((PRP) OR (PRF) OR (PRGF) OR (CGF)) AND (endodontic) AND ((treatment) OR (therapy))". After screening of 155 results, 14 articles were included in this review. Different types of platelet concentrates are able to stimulate the processes of proliferation and differentiation of mesenchymal stem cells. Platelet rich fibrin (PRF) releases growth factors for at least 7 days at the application site. Growth factors and released cytokines stimulate the activity of osteoblasts. Moreover, the release of growth factors accelerates tissue regeneration by increasing the migration of fibroblasts. It was not possible to assess the efficacy of PRF supplementation in the treatment of endodontic periapical lesions in permanent, mature teeth with closed apexes, due to the lack of well-designed scientific research. Further studies are needed to analyze the effect of PRF on the healing processes in the periapical region.

Abstract
Platelet-rich fibrin (PRF) is an autologous blood concentrate obtained without anticoagulants by centrifugation of patients’ peripheral venous blood. PRF is considered to enhance the formation of new bone. The aim of this manuscript was to present two case reports of permanent teeth with closed apexes with periapical lesions, treated endodontically with the use of PRF. The root canals were mechanically cleaned and shaped with NiTi files and irrigated with 5.25% sodium hypochlorite (NaOCl), 40% citric acid (CA), and triple distillated water. Before the canal systems were obturated, A-PRF was used as a scaffold and was placed below the cementodentinal junction with hand pluggers. Cone beam computerized tomography (CBCT) was used to assess the resolutions of periapical radiolucencies. After 6 months, the measurements of both periapical lesions were significantly reduced. Although the performed root canal treatments (RCTs) can definitely be recognized as successful, it must be emphasized that mechanical shaping and cleaning of the root canals with special disinfecting solutions significantly affect the clinical efficacy of RCT. It seems impossible to state that PRF played a leading role in the healing process of the presented periapical lesions. Further studies must be performed to assess whether RCT of mature teeth with an additional PRF application is superior to RCT performed alone.

Abstract
AIM To compare the diagnostic accuracy of periapical radiography (PR) and cone-beam computed tomography (CBCT) for detecting pathoses of endodontic origin using the gold standard of direct surgical visualization. METHODOLOGY Seventy-four patients (112 teeth) underwent radiographic examination by periapical radiography and CBCT. The presence of periapical lesions, root perforations and their locations, root fractures, different types of external root resorptive defects, apicomarginal bone defects, through and through bone defects, buccal bone status and proximity of root apices and lesions to vital anatomical structures were assessed. These same parameters were assessed intraoperatively by direct surgical visualization which served as the gold standard reference for the radiographic assessments. Sensitivity, specificity, positive predictive values, negative predictive values were determined for comparison of diagnostic accuracy between two modalities. RESULTS There were no significant differences between the two imaging modalities for root resorptive defects and root fractures. However, CBCT accurately detected periapical lesions, root perforations, apicomarginal bone defects and through and through bone defects. The overall accuracy of CBCT varied from 91% to 96% in detecting dehiscence and fenestration of buccal cortical plates. CONCLUSION Overall, CBCT had a higher diagnostic accuracy in complex endodontic pathoses compared to PR. Nevertheless, CBCT failed to diagnose apicomarginal bone defects in 33% teeth. In evaluating the status of buccal cortical plate from CBCT images, observers could detect absence of bone better than its presence. Thus, limited FOV CBCT should be considered for selective cases where periapical radiography has diagnostic ambiguity.

Abstract
The role of platelet-rich plasma (PRP) in promoting the healing of bone fractures has not yet been clearly stated. The aim of this prospective clinical study was to evaluate the effectiveness of plasma rich in growth factors (PRGF, a PRP derivate) in the treatment of naturally-occurring bone fractures in dogs. With this objective, sixty-five dogs with radius/ulna or tibia/fibula bone fractures were randomly divided into two groups (PRGF and saline solution (SS) groups) and checked at days 0, 7, 14, 21, 28, 35, 42, 49, 56, 60, 63, 70, 120, and 180. All the fractures were treated with an external skeletal fixation, and pain was controlled with Carprofen. Healing was evaluated by physical examination, limb function, radiography, and by a Likert-type owner satisfaction questionnaire. A faster fracture healing was observed in the PRGF group, with statistically significant differences with respect to the SS group. Swelling at the fracture site was significantly greater at day 14 and 28 in animals injected with PRGF, and more pain on palpation was found in the area at day 28. The injection of PRGF in acute bone fractures accelerates bone healing.

Abstract
PURPOSE To evaluate the histologic and histomorphometric data 10 years after grafting of maxillary sinus in a case using anorganic bovine bone matrix (ABBM) and plasma rich in growth factors (PRGF). MATERIALS AND METHODS Histomorphometric measures were performed for newly formed bone, ABBM particles remnants, marrow spaces, and the presence of osteoblastic and osteoclastic activity. RESULTS Histologic analysis showed ABBM particles surrounded by new compact and mature vital bone. Osteocytes were noted within lacunae. Some osteoblastic and osteoclastic activity could be identified. The histomorphometric results were 21.7% of newly formed bone, 33.9% of ABBM, and 44% was composed of marrow spaces. CONCLUSIONS After 10 years postoperatively, the histologic evaluation of this case report demonstrated slow replacement of the ABBM particles by newly formed bone, even with the addition of PRGF. The residual ABBM particles were found in close contact to the newly formed bone.

Abstract
The current literature was reviewed to determine the impact of autologous platelet concentrates (APCs) on endodontic healing. All types of clinical study designs concerning any kind of endodontic treatment involving the application of APCs were included. Two independent reviewers searched three databases (PubMed, Embase, and Cochrane Library) for studies, complemented by hand search, until 16/1/2016. From the 423 identified records, 48 articles met the inclusion criteria. Selected randomized controlled clinical trials (RCTs) underwent Cochrane Collaboration's risk-of-bias assessment and data extraction. Only two RCTs showed low risk of bias. There was considerable heterogeneity between the RCTs with regard to the type of therapy, type of APCs, assessment method, and study quality, and therefore the data could not be analyzed quantitatively. The included case reports/series and non-randomized comparative studies underwent qualitative analysis with the revised Methodological Index for Non-Randomized Studies (MINORS) and data extraction. The two comparative non-randomized studies scored qualitatively high, though the MINORS-scores of the case series and reports were dispersed. APCs were involved in five endodontic treatment modalities, namely apexification, regenerative endodontic procedures, pulpotomy, apical surgery, and treatment of endo-perio/perio-endo lesions. APCs seem to accelerate postoperative bone healing, augment the patients' postoperative quality of life, aid further root development, and support maintenance/regaining of pulp vitality. No adverse events were reported. APCs in endodontic treatments seem to contribute to the healing of soft and hard tissues, though there is a lack of long-term high quality clinical trials and standardized treatment protocols.

Abstract
Tooth related factors such as palatoradicular groove can be one of the causes for localized periodontal destruction. Such pathological process may result in apicomarginal defect along with inflammation of pulp. This creates challenging situation which clinician must be capable of performing advanced periodontal regenerative procedures for the successful management. This case report discusses clinical management of apicomarginal defect associated with extensive periradicular destruction in a maxillary lateral incisor, along with histopathologic aspect of the lesion.

A new bone substitute in the definitive management of furcation involvement: a case report. W INDIAN MED J 2014; 63:197-200. [PMID: 25303262 DOI: 10.7727/wimj.2012.321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2012] [Revised: 02/28/2013] [Accepted: 03/01/2013] [Indexed: 11/18/2022]
Abstract
Bone xenografts are used for reconstructive surgery in medicine and dentistry. The grafts are osteoconductive, serving as a matrix in bone regeneration. Furcation involvements are one of the most challenging clinical problems in periodontics. Unilab Surgibone is a bone xenograft and has been investigated in many clinical and experimental studies. In this case report, a 50-year old male patient was diagnosed with a Class III furcation problem in his upper right first molar. The tooth was surgically treated by resection of the distobuccal root after the flap elevation. The extraction defect was grafted with the Unilab Surgibone. After nine months, the patient was evaluated clinically and radiographically. The healing was uneventful. The clinical and radiographic data suggest that Unilab Surgibone supports bone regeneration.

Chrcanovic BR. Open versus closed reduction: comminuted mandibular fractures. Oral Maxillofac Surg 2013; 17:95-104. [PMID: 22842858 DOI: 10.1007/s10006-012-0349-2] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2012] [Accepted: 07/18/2012] [Indexed: 06/01/2023]
Abstract
PURPOSE The purpose of the study was to review the literature regarding the evolution of current thoughts on management of comminuted mandibular fractures (CMFs). METHODS An electronic search in PubMed was undertaken in May 2012. The titles and abstracts from these results were read to identify studies within the selection criteria. Eligibility criteria included studies published in English or German reporting clinical series of CMFs. RESULTS The search strategy initially identified 409 studies. Fifteen studies were identified without repetition within the selection criteria. One case report article showing significance in the development of treatment techniques was included. Additional hand-searching yielded five additional papers. Thus, a total of 21 studies were included. CONCLUSIONS Open reduction and internal fixation (ORIF) in cases of CMFs are indicated in (a) severe injuries with significant displacement to allow restoration of pretraumatic anatomic relationships, (b) in the edentulous and semi-dentate patient, who may benefit from ORIF of CMFs when stable occlusal relationships are absent, and (c) in cases with multiple fractures of the midface, in which the mandible has to serve as a guide to reposition the midfacial bones. However, there is still a place for closed reduction/conservative treatment (CTR). ORIF in CMFs is not indicated in cases of minimally displaced comminuted fractures that could easily and adequately be treated with CTR. If the surgical team is not well versed in the nuances of rigid internal fixation, or the necessary equipment is not available, it is far better to do simple CTR. However, it would be more reasonable to refer the patient to a hospital that can provide means of ORIF in cases of clear indication of its use in CMFs. In cases where ORIF is indicated, stabilization by compression or any other form of load-sharing osteosynthesis is obviously contraindicated because small fragments cannot be compressed and are not capable of sharing loads. Thus, the ORIF of CMFs is best performed using load-bearing osteosynthesis; most experience has been gained with 2.7-mm reconstruction plates. External pin fixation could be used in cases when there is so much comminution, soft tissue disruption (mostly gunshot wounds), and there are inadequate teeth on either side of the comminuted fracture to control the spatial relationship of the remaining mandibular fragments with maxillomandibular fixation (MMF).

Abstract
INTRODUCTION The aim of this retrospective investigation was to evaluate the postoperative quality of life after endodontic surgery in maxillary molars when a sinus membrane perforation occurred and platelet concentrates were used. MATERIALS AND METHODS Included patients were treated by microsurgical endodontic treatment in molar and premolar maxillary regions between 2007 and 2010. Patients who fulfilled the inclusion criteria were screened. Data from the quality of life questionnaire were analyzed. The use of plasma rich in growth factors (PRGF) (test group) was compared with a control group when a Schneiderian membrane perforation occurred during endodontic surgery performed with a modern technique in maxillary molars and premolars. RESULTS A total of 20 patients (12 in the control group and eight in the test group) fulfilled the inclusion criteria. No differences were evaluated at baseline for clinical parameters. Significantly improved patients' quality of life was observed in the test group considering symptoms as swelling, bad breath or taste, and pain. Functional activities were less impaired in the test group and swelling was significantly higher in the control group. In the test group, pain was significantly lower than the control group during the first 6 days after surgery and also, the consumption of painkillers was lower for patients belonging to the test group even if it was not statistically significant. DISCUSSION In general, a small sinus membrane perforation (less than 6 mm) during endodontic surgery did not cause severe complications. The use of platelet concentrates could be effective in reducing the impact on patients' quality of life, decreasing pain and surgery side effects as well as swelling.

Abstract
INTRODUCTION Control of postoperative discomfort might enhance the patient's quality of life and treatment acceptance. The aim of the present randomized single-blind study was to evaluate whether the use of platelet concentrate during endodontic surgery might have a favorable impact on pain and other factors related to patient's quality of life during the first week after surgery. METHODS Eighteen patients with periapical lesion were treated with modern endodontic surgical procedure (control group). In another 18 patients, in adjunct to surgical procedure, platelet concentrate was applied on the root end in liquid form, within the bone defect in clot form, and over the suture in liquid form (test group). All patients completed a questionnaire for evaluation of main symptoms and daily activities during the first week after surgery. The outcomes of the questionnaires of the 2 groups were statistically compared. RESULTS The test group showed significantly less pain and swelling, fewer analgesics taken, and improved functional activities as compared with the control group. CONCLUSIONS The adjunct of platelet concentrate to the endodontic surgical procedure produced significant beneficial effect to patients' quality of life during the early postoperative stage.
