Abstract
Background Bone fracture regeneration poses significant clinical challenges due to complications such as delayed healing, nonunion, and the limitations of current treatments. Objective This study introduces a novel therapeutic approach utilizing biomimetic nanogels to silence the Ccl4 gene, aiming to promote bone repair by regulating macrophage polarization. Methods The nanogels, composed of tannic acid (TA) and small interfering RNA (siRNA), were designed for targeted gene delivery. Results In vitro findings indicate that siRNA-mediated Ccl4 reduction significantly improves M2 macrophage polarization, which, in turn, promotes osteogenic differentiation of bone marrow-derived mesenchymal stem cells. Increased expression of osteogenic markers and enhanced mineral deposition were observed. The nanogels demonstrated optimal particle size, stability, and cellular uptake, and biocompatibility assays confirmed their non-toxicity. Conclusion This study underscores the potential of targeted siRNA delivery in modulating immune responses to enhance bone regeneration, offering promising treatment options for complex bone healing scenarios.

Bennardo F, Barone S, Antonelli A, Giudice A. Autologous platelet concentrates as adjuvant in the surgical management of medication-related osteonecrosis of the jaw. Periodontol 2000 2024. [PMID: 39345044 DOI: 10.1111/prd.12608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 08/13/2024] [Accepted: 08/15/2024] [Indexed: 10/01/2024]
Abstract
Medication-related osteonecrosis of the jaw (MRONJ) is an infectious side effect associated with bisphosphonates and monoclonal antibodies (denosumab, immune modulators, and antiangiogenic medications). Adjunctive therapies for the surgical management of MRONJ include autologous platelet concentrates (APCs). These APCs serve as a source of various cells and growth factors that aid tissue healing and regeneration. This review evaluated the use of platelet-rich plasma (PRP), plasma-rich in growth factors (PRGF), and leukocyte- and platelet-rich fibrin (L-PRF) as adjuvant therapies for the surgical management of MRONJ by conducting analyses on the results of 58 articles. Compared to surgical treatment alone, the application of PRP and L-PRF after surgery appears to increase healing in the management of patients with MRONJ. No studies have reported unhealed lesions as a result of surgical treatment of MRONJ with PRGF application or compared it with surgical treatment alone. The overall results of this review have shown favorable healing rates of MRONJ lesions managed with the application of APCs after surgical treatment; however, significant methodological limitations may limit the scientific evidence supporting their use. Further randomized controlled trials with strict criteria are needed to establish the extent to which APCs can improve wound healing and quality of life in patients with MRONJ requiring surgical treatment.

Abstract
OBJECTIVES Medication-related osteonecrosis of the jaw (MRONJ) is a significant complication associated with bisphosphonates, impacting jaw osteoclasts, and causing altered bone remodelling. Prevention involves stabilizing systemic pathology, considering antiresorptive therapies, and exploring platelet-rich fibrin (PRF) for wound healing and tissue regeneration. The study aims to assess the efficacy of PRF in MRONJ treatment and highlight research gaps for more robust investigations. METHODS Following PRISMA and MOOSE guidelines, this systematic review and meta-analysis included English publications from 2013 to 2023, employing a systematic search in databases such as MEDLINE, Scopus, and Web of Science. Quality assessment used the Cochrane Collaboration's tool and the NOS, with the main meta-analysis concentrating on PRF-treated MRONJ cases, assessing resolution rates, and prioritizing healing outcomes and infection absence as primary endpoints. RESULTS The study, encompassing 11 articles and 480 participants with MRONJ, demonstrated that in stage 1 procedures, PRF significantly outperformed conventional medical treatments (OR: 2.93, 95% CI: 1.54-5.59, P=0.001), particularly at the mandible site (OR: 1.65, 95% CI: 0.86-3.17, P=0.13). PRF also exhibited significantly superior healing outcomes compared with conventional medical treatments (OR: 4.45, 95% CI: 1.58-12.53, P=0.005), supporting its consideration as a valuable alternative in specific MRONJ management scenarios. CONCLUSION This study highlights PRF's effectiveness in early MRONJ interventions and specific anatomic sites, despite acknowledged limitations, emphasizing the need for further research, and supporting its consideration in MRONJ surgical management.

Bisphosphonate therapy in the management of diffuse sclerosing osteomyelitis of the mandible: a systematic review and narrative synthesis. Ann Med Surg (Lond) 2024; 86:950-957. [PMID: 38333319 PMCID: PMC10849439 DOI: 10.1097/ms9.0000000000001561] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 11/18/2023] [Indexed: 02/10/2024] Open
Abstract
Background Diffuse sclerosing osteomyelitis (DSO) affecting the mandible is an uncommon condition characterised by recurrent pain and functional disturbances. Traditional treatments involving antibiotics, steroids, and analgesics have generally yielded unsatisfactory results. Numerous articles have proposed the utilisation of bisphosphonate therapy as an alternative approach to achieve sustained symptom relief. This study aims to consolidate the available evidence on the effectiveness of bisphosphonate therapy in managing DSO. Methods A systematic review protocol was registered with PROSPERO and reported in accordance with the Preferred Reporting for Items for Systematic Reviews and Meta-Analyses. Comprehensive electronic search strategies were devised, and studies were screened based on predefined inclusion and exclusion criteria. Results Ten articles met the eligibility criteria, encompassing a total of 135 patients diagnosed with DSO who received bisphosphonate treatment. All included studies consistently reported a reduction in pain levels and swelling, along with a decrease in the cumulative use of analgesics. The majority of patients reported long-lasting symptom improvement with bisphosphonate therapy. Notably, four studies documented improvements in maximal mouth opening, with one study reporting a mean increase of 9.6mm. Furthermore, six studies observed improvements in panoramic radiographs and cone beam computed tomography scans, with one publication describing two patients exhibiting near-normal bone architecture. Importantly, all studies reported the absence of long-term complications. Conclusions Bisphosphonate therapy emerges as a promising treatment modality for DSO, exhibiting efficacy in symptom alleviation and radiological enhancement while conferring lasting benefits. Nevertheless, further prospective studies are warranted to refine treatment protocols and substantiate these findings.

Abstract
BACKGROUND Osteoporosis, as a musculoskeletal disease, is very common, especially in the era of aging society. It is described by a reduction in bone strength and increased risk of fractures, which are linked to considerable morbidity, mortality, and high healthcare burdens. Bisphosphonates are the most commonly used drugs to manage osteoporosis and they consequently reduce fracture risk. However, one of the clinical challenges is fear of side effects in patients who are using bisphosphonates as the administration of these drugs is lengthy. Ocular inflammation has been reporting as one of the potential vision-threatening side effects of bisphosphonates. PURPOSE To review previously reported ocular inflammation in patients taking bisphosphonates. METHOD A literature survey was conducted using databases in order to collect data for a narrative review of published reports regarding ocular side effects of bisphosphonates. RESULTS People taking bisphosphonates were at a relatively low risk of ocular inflammation, with the onset from a few hours after exposure up to more than 3 years. The release of inflammatory mediators mainly by activated gamma delta T cells in response to bisphosphonates was the main cause of ocular inflammation. CONCLUSION Strategies for treating patients with osteoporosis should consider the potential ocular side effects of bisphosphonates. Ocular inflammation, as one of the side effects of bisphosphonates, is a serious sight-threatening sign and should be taken seriously. Greater awareness of the association between bisphosphonate use and ocular inflammation may allow for earlier identification and timely treatment of future cases.

Abstract
The aim is to analyze the relationship and significance of the FOS, FOSB, Suppressors of cytokine signaling (SOCS), and hypoxia-inducible factor 1 (HIF1) gene loci and their polymorphisms with periodontitis and osteopenia in the Chinese population. In this case-control study, data on questionnaires, periodontal examination, bone mineral density, and FOS, FOSB, SOCS3, and HIF1 gene loci and their polymorphisms were obtained from 474 participants. The data were analyzed using the analysis of variance, Kruskal-Wallis test, χ2 test, and logistic regression. The incidence of osteopenia was significantly increased in patients with periodontitis compared to controls (58.6 vs. 34.4%, P < 0.001). Accordingly, the risk was increased 2.21-fold compared with controls (95% CI 2.09-4.95). Osteopenia patients had a significantly higher risk of periodontitis than patients with normal bone density (OR = 3.22, 95% CI 2.09-4.94). There were significant positive associations between FOSB and SOCS3 polymorphisms and periodontitis and osteopenia susceptibility. Individuals carrying the G/G genotype of the FOSB gene rs708905 locus had an increased risk of periodontitis (OR = 5.06, 95% CI 2.36-10.86) and osteopenia (OR = 3.26, 95% CI 1.34-7.96). Compared with the C/C genotype, the A/A genotype of the FOSB rs8105114 locus was associated with a significantly higher risk of periodontitis (OR = 2.14, 95% CI 1.02-4.53) and osteopenia (OR = 2.85, 95% CI 1.12-7.22). Compared with the A/A genotype, the risk of periodontitis in the G/G genotype of the SOCS3 rs7207782 locus was increased 3.10-fold (P < 0.001), and the risk of osteopenia was increased 2.01-fold (P = 0.023). There was a bidirectional relationship between periodontitis and osteopenia. The rs708905 G/G and rs8105114 A/A genotypes of FOSB and the rs7207782 G/G genotype of SOCS3 were risk factors for both periodontitis and osteopenia in the Chinese population, which could increase knowledge about disease‑specific and cross‑disease genetic pattern.

Abstract
The abnormal growth of the craniofacial bone leads to skeletal and dental defects, which result in the presence of malocclusions. Not all causes of malocclusion have been explained. In the development of skeletal abnormalities, attention is paid to general deficiencies, including of vitamin D3 (VD3), which causes rickets. Its chronic deficiency may contribute to skeletal malocclusion. The aim of the study was to assess the impact of VD3 deficiency on the development of malocclusions. The examination consisted of a medical interview, oral examination, an alginate impression and radiological imaging, orthodontic assessment, and taking a venous blood sample for VD3 level testing. In about 42.1% of patients, the presence of a skeletal defect was found, and in 46.5% of patients, dentoalveolar malocclusion. The most common defect was transverse constriction of the maxilla with a narrow upper arch (30.7%). The concentration of vitamin 25 (OH) D in the study group was on average 23.6 ± 10.5 (ng/mL). VD3 deficiency was found in 86 subjects (75.4%). Our research showed that VD3 deficiency could be one of an important factor influencing maxillary development. Patients had a greater risk of a narrowed upper arch (OR = 4.94), crowding (OR = 4.94) and crossbite (OR = 6.16). Thus, there was a link between the deficiency of this hormone and the underdevelopment of the maxilla.

Abstract
OBJECTIVES The aim of this study was to find out the prognosis of medication-related osteonecrosis of the jaws (MRONJ) in prostate cancer patients who received two different types of antiresorptive agents for bone metastasis. MATERIALS AND METHODS We retrospectively surveyed a cohort of 95 metastatic prostate cancer patients with 122 MRONJ lesions treated in a single medical center. Treatment outcomes and prognostic factors were investigated. The cumulative complete response rate was calculated with the Kaplan-Meier method, and significance was examined with the log-rank and Breslow tests. Cox regression was used for the univariate and multivariate analyses of prognostic factors. RESULTS The cumulative complete response rate of all patients at 12 months was 37.8%, and that of patients treated with zoledronic acid and denosumab was 22.9% and 70.5%, respectively. Denosumab, pretreatment C-terminal telopeptide of collagen I (CTX) level > 150 pg/ml, and anemia were identified as independent prognostic factors in a multivariate analysis with adjusted hazard ratios of 3.18 (95% confidence interval [CI], 1.24-8.11), 3.24 (95% CI, 1.39-7.53), and 0.42 (95% CI, 0.19-0.93), respectively. CONCLUSION A higher pretreatment level of CTX, using denosumab as the antiresorptive agent and without anemia, indicates a better treatment outcome of MRONJ in prostate cancer patients.

Abstract
The jawbone is a peculiar type of bone tissue, unique for its histological, anatomical and physiological characteristics. Therefore, a defect in the maxilla or in the mandible, because of pathological sequelae is difficult to prevent and to restore. Several biomaterials have been and are currently being developed to respond to the demands of regenerative medicine. A specific group of biomaterials used in regenerative dentistry is represented by the autologous materials. Platelet concentrates harvested bone and dentin derivates are indeed used in an attempt to minimise the alveolar resorption or in vertical ridge augmentation procedures or in sinus lift interventions. The aim of this review is to examine the properties of the above-listed materials, to compare them and to indicate eventual clinical applications.

Abstract
The field of regeneration interventions in oral and maxillofacial surgeries still represents a challenge for researchers and clinicians. Understanding the biological and morphological behaviour of human cells towards the materials used for the regeneration surgeries is key to successfully choosing and applying the appropriate biomaterials for specific clinical situations. The aim of the study was the biological and morphological evaluation of autologous platelet concentrate materials obtained with different protocols, in culture with human periodontal ligament fibroblasts (HPLF). The study design included the evaluation of Leukocyte-Platelet-Rich-Fibrin (L-PRF), Concentrated Growth Factors (CGF) and autologous platelet gel (APG) in contact with the HPLF cell line after 24 h, 72 h and 7 days of in vitro culture. Cell proliferation and, therefore, viability were evaluated with XTT assays. The morphological response of the cells was evaluated by light microscopy, scanning electron microscopy and confocal microscopy. The XTT assay showed an interesting response in the growth curve. In particular, the material that gave the best results was the CGF. The morphological data supported the XTT assay, showing the best results for the CGF and L-PRF. In conclusion, all the platelet-derived materials stimulated the onset of the growth of the HPLF cell line, making them promising options for periodontal regeneration interventions.

Abstract
The aim of this systematic review was to answer the question: Is the application of autologous platelet concentrates (APCs) effective in the prevention and treatment of medication-related osteonecrosis of the jaw (MRONJ)? A literature search of PubMed, Scopus, and Web of Science databases (articles published until June 30, 2019) was conducted, in accordance with the PRISMA statement, using search terms related to "platelet concentrate" and "osteonecrosis". The Jadad scale was used to assess the quality of the articles. Fisher's exact test was used to evaluate eventual differences between groups. Of 594 articles, 43 were included in the review (8 for MRONJ prevention and 35 for MRONJ treatment). Out of a total of 1219 dental extractions recorded (786 with APCs), only 12 cases of MRONJ have been reported (1%), all in patients with a history of high-dose antiresorptive treatment, and regardless of the use of APCs (p = 0.7634). Regarding MRONJ treatment, there were no statistically significant differences in terms of improvement between APC application and surgical treatment alone (p = 0.0788). Results are not sufficient to establish the effectiveness of APCs in the prevention and treatment of MRONJ. Randomized controlled trials with large sample size are needed.

Abstract
Osteonecrosis of the jaw (ONJ) is a rare but serious drug induced adverse event, mainly associated with the use of antiresorptive medications, such as intravenous (IV) bisphosphonates (BPs) in cancer patients. In this review, we evaluated all the pharmacogenomic association studies for ONJ published up to December 2018. To date, two SNPs (CYP2C8 rs1934951 and RBMS3 rs17024608) were identified to be associated with ONJ by two genome-wide association studies (GWAS). However, all six subsequent candidate gene studies failed to replicate these results. In addition, six discovery candidate gene studies tried to identify the genetic markers in several genes associated with bone remodeling, bone mineral density, or osteoporosis. After evaluating the results of these 6 studies, none of the SNPs was significantly associated with ONJ. Recently, two whole-exome sequencing (WES) analysis (including one from our group) were performed to identify variants associated with ONJ. So far, only our study successfully replicated discovery result indicating SIRT1 SNP rs7896005 to be associated with ONJ. However, this SNP also did not reach genome-wide significance. The major limitations of these studies include lack of replication phases and limited sample sizes. Even though some studies had larger sample sizes, they recruited healthy individuals as controls, not subjects treated with BPs. We conclude that a GWAS with a larger sample size followed by replication phase will be needed to fully investigate the pharmacogenomic markers of ONJ.

Osteoclastogenesis Behavior of Zirconia for Dental Implant. MATERIALS 2019; 12:ma12050732. [PMID: 30836587 PMCID: PMC6427278 DOI: 10.3390/ma12050732] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/28/2019] [Revised: 02/20/2019] [Accepted: 02/26/2019] [Indexed: 01/18/2023]
Abstract
Zirconia is worth studying as an alternative to dental titanium implants to overcome the disadvantages of titanium. This study investigated the surface characteristics of the zirconia implant material and osteoclastogenesis responses on the surface compared with titanium. Yttrium oxide-stabilized 5% tetragonal zirconia polycrystalline specimens were manufactured, and osteoclast-precursor cells were cultured and differentiated into osteoclasts on the specimens. Surface shape, roughness, and chemical composition were evaluated. After culturing, cell morphologies and differentiation capacity were analyzed using tartrate-resistant acid phosphatase activity (TRACP). mRNA of two critical transcription factors, nuclear factor of activated T-cells 1 (NFATc1) and c-Fos were measured, and protein levels of NFATc1 and c-Fos were investigated. The zirconia specimens had rhomboid-like shapes with smooth surfaces and exhibited no difference in surface roughness compared to the titanium specimens. Morphologies of differentiated osteoclasts on both materials were similar. TRACP activity on the zirconia showed comparable results to that on the titanium. The mRNA value of NFATc1 on the zirconia was higher than that on the titanium at day four. The protein level of c-Fos was expressed thicker on the zirconia when compared to the titanium at day two. The results of this study suggest that zirconia material provides adequate osteoclastogenesis behaviors for dental implant use.

Sturrock A, Preshaw PM, Hayes C, Wilkes S. Perceptions and attitudes of patients towards medication-related osteonecrosis of the jaw (MRONJ): a qualitative study in England. BMJ Open 2019; 9:e024376. [PMID: 30833319 PMCID: PMC6443056 DOI: 10.1136/bmjopen-2018-024376] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Revised: 12/15/2018] [Accepted: 01/08/2019] [Indexed: 12/26/2022] Open
Abstract
OBJECTIVE To explore the impact of medication-related osteonecrosis of the jaw (MRONJ) on quality of life and to explore the attitudes and perceptions of patients towards the multidisciplinary approach to the prevention of the condition. DESIGN Interpretivist methodology using qualitative semistructured interviews. SETTING Primary care general medical practices and secondary care dental services in England. PARTICIPANTS 23 patients; 6 with MRONJ, 13 prescribed bisphosphonates, 4 with osteoporosis not currently prescribed any medication. RESULTS Patients felt that MRONJ had a significant negative impact on their quality of life and had poor knowledge of the preventive strategies recommended in the literature. Patients demonstrated positive attitudes towards a multidisciplinary approach to care; however, they perceived prescribers as having the key role in articulating risk. Four salient and inter-related themes emerged from the interviews: (1) perception of knowledge, indicating limited awareness of the condition, risk factors and preventive strategies; (2) quality of life, indicating the lived experiences of patients and the physical, psychological and social impacts of MRONJ; (3) interprofessional management, indicating a perceived organisational hierarchy, professional roles and responsibilities, prioritising aspects of care, articulation of risk and communication and (4) wider context, indicating demands on National Health Service resources and barriers to dental care. CONCLUSIONS MRONJ has a significant detrimental impact on quality of life, yet appropriate preventative education is not apparent. Effective interprofessional patient education and prevention to mitigate against the risk of developing MRONJ is required.
