Abstract
Introduction: To properly combine osteoporosis treatment with dental treatment and to prevent medication-related osteonecrosis of the jaw (MRONJI), a system of communication between health providers can be smoothly made within a short time is required. With the recent increase in the possibility of telemedicine being introduced in Korea, it is expected that the introduction of teleconsultation between health providers treating osteoporosis will reduce the discomfort of patients and health providers and improve satisfaction. In this study, a survey was conducted on the knowledge and experience of MRONJ to find out the willingness of dentists treating osteoporosis patients for teleconsultation. Methods: An online questionnaire-based survey was conducted to investigate the intention for teleconsultation for MRONJ with a total of 516 dentists between September and October 2021. Results: Two-thirds of the respondents had experience of requesting consultation other dentists or doctors for the osteoporosis or MRONJ patients. They answered that the referral letter was the most used consultation request method and that it took a long time to get a reply. As for the intention of teleconsultation, 70% of the respondents answered that they were willing. The more experienced or the higher the educational level, the higher the intention for teleconsultation. Although the intention of dentists for teleconsultation was high, satisfaction with the cost of teleconsultation was low. Discussion: Although dentists' intention to use teleconsultation was high, satisfaction with the cost of medical care for teleconsultation was low, so it seems that this should be coordinated.

Abstract
OBJECTIVES Anti-resorptive agents have been linked to the development of MRONJ in patients undergoing dental surgical procedures. This survey aims to explore the level of knowledge and experience of Italian Society of Periodontology and Implantology members in the management of patients treated with anti-resorptive agents and with the risk of developing MRONJ. MATERIALS AND METHODS An 18-item questionnaire was submitted by e-mail to the SIdP members. Statistical analyses were carried out. Continuous variables were described as mean ± standard deviation (SD) or median, and first and third quartile according to distribution's normality. Normality of data was checked with Shapiro-Wilk test. RESULTS Four hundred and fifty-one questionnaires were returned by e-mail (32%). Most of the respondents were private practitioners (81.8%). Only 47.7% declared to be highly confident in managing patients on anti-resorptive therapy while 92.5% reported to have performed tooth extractions and 52.3% implant surgery in patients under anti-resorptive therapy for osteometabolic disorders. One or more MRONJ-affected patients were encountered by 63.2% of the respondents. CONCLUSIONS This survey highlights the need to develop a "dedicated" program both for dentists and prescribers to improve the level of cooperation and to increase the level of awareness of patients treated with anti-resorptive agents.

Abstract
BACKGROUND Bisphosphonates (BPs) are often used in treating benign and malignant disorders. Medication-related osteonecrosis of the jaw (MRONJ) is a significant problem that arises from the long-term use of BPs. OBJECTIVE In this study, we assessed the knowledge of students and dentists about MRONJ in the central region of Saudi Arabia. METHODS A cross-sectional study was conducted to collect information from dental students and practitioners from the central region of Saudi Arabia. A valid, reliable, and structured questionnaire was used to gather data using a non-probability convenient sampling technique. IBM SPSS Statistics for Windows, Version 22.0 (Released 2013; IBM Corp., Armonk, New York, United States) was used to analyse the data. The descriptive data were expressed as frequencies and percentages to evaluate the association between dentists and students concerning overall knowledge related to osteonecrosis of the jaw, and a chi-squared test was applied. RESULTS In total, 250 individuals completed the questionnaire. The general knowledge of antiresorptive/antiangiogenic medications showed that most dentists (87.5%) and students (68.4%) knew about BP medications. A general lack of understanding about the therapeutic uses of antiangiogenic and antiresorptive medications was demonstrated by the participants. A significant proportion of dentists (58.8%) and students (50.9%) were not convinced that invasive dental procedures can be safely performed on patients receiving intravenous BP therapy. A significant proportion of the participants in the sample were unclear of the principal diseases that antiresorptive and antiangiogenic medications target. A mere 22% of respondents were aware of the accurate definition of medications-related MRONJ. CONCLUSION There is insufficient knowledge about MRONJ among students and practitioners. Therefore, these findings suggest increased emphasis should be placed on educating dentists and students about this condition to ensure patients receive the best possible care.

Abstract
BACKGROUND Medication-related osteonecrosis of the jaw (MRONJ) is a condition that affects the jaws and is characterized by exposed bone in the oral cavity that persists for more than eight weeks despite treatment. Additional criteria include that the patient should have a current or past history of antiresorptive drugs and/or in combination with antiangiogenic drugs, absence of metastasis, and no previous radiotherapy to the affected area. The radiographic features of MRONJ in most instances do not have any specific radiographic features. This is because standard radiographs usually show no stark abnormalities in the early stages of the disease. OBJECTIVE The study aimed to evaluate if any specific radiographic patterns are associated with primary cancers and between medications. MATERIALS AND METHODS The study is an observational case series. A total of 50 cases of possible osteonecrosis from June 2010 to June 2013 archives of the Department of Oral and Maxillofacial Radiology were assessed. Based on the history, 12 cases that had a history of medication use that could lead to medication-related osteonecrosis of the jaw (MRONJ) were selected. Cone beam computed tomography (CBCT) scans of these 12 cases were evaluated using the CBCT reconstruction program InVivo Dental version 6 (Anatomage Inc., San Jose, CA, USA). The number of areas showing sequestration, the pattern of osteonecrosis, and the extent were assessed. Primary cancer and the type of medication were also assessed to identify if certain cancers or drugs showed any distinctive pattern of osteonecrosis. Reconstructed panoramic images and true three-dimensional (3D) multi-planar images were assessed to study the condition. An oral and maxillofacial radiology resident in training and a board-certified oral and maxillofacial radiologist assessed the images. RESULTS Radiographic findings varied among the 12 cases and included generalized sclerosis, osteosclerosis with widened periodontal ligament (PDL) space, bony sequestra, and bony necrosis. However, no specific or distinctive radiographic patterns were observed in any of the cases, regardless of the type of primary cancer or medication used. CONCLUSION It is challenging to radiographically distinguish between MRONJ cases with different primary cancer and/or medication. FUTURE DIRECTIONS Future studies should include evaluating larger samples with varying primary cancers and medications and combination drug therapies. Cases in an advanced stage of MRONJ do not have distinctive features due to extensive destruction and superimposed infection; it may be valuable to evaluate patients in the early stages of MRONJ to better understand distinguishing radiographic patterns specific to certain primary cancers or medications.

Abstract
Aim: The purpose of the study was to analyze the knowledge of dentists in Belo Horizonte, Brazil, about bisphosphonates and their clinical implications. Methods: A cross-sectional questionnaire-based study was conducted with a convenience sample of dentists in Belo Horizonte, in a period of 8 weeks. The questionnaire was self-applied and was structured with 10 items about the dentists’ demographic characteristics, professional profile, and knowledge about bisphosphonates. Associations in the data were analyzed by with the Fischer’s exact test with a significance level of 5%. Results: Of the 214 participating dentists, 163 (76.17%) were women, and 51 (23.83%) were men, with age ranged for 21 to 73 years (mean of 30 years) and mean of 6 years of professional activity. Nearly half (106/49.53%) reported having knowledge about bisphosphonates, and undergraduate courses were the primary source of such information (73/34.11%). Osteoporosis was the most identified indication for use (75/35.04%), although no participants correctly identified all indications. Regarding the drugs’ side effects, only three dentists (1.40%) could correctly identify all responses, with bone necrosis being recognized by the majority (88/41.12%). Sodium alendronate (54/25.23%) and sodium ibandronate (15/7.01%) were the most identified examples of bisphosphonates. Last, only nine dentists (4.20%) could identify all examples of the drugs, and their capacity was associated with self-reported knowledge (p<0.05). Conclusions: More information about bisphosphonates should be disseminated in Belo Horizonte, ideally via better approaches in local undergraduate and postgraduate courses. Until then, knowledge of the basic aspects of bisphosphonates will remain limited.

Evaluation of Medication-Related Osteonecrosis of the Jaw (MRONJ) in Terms of Staging and Treatment Strategies by Dental Students at Different Educational Levels. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59020252. [PMID: 36837455 PMCID: PMC9962432 DOI: 10.3390/medicina59020252] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Revised: 01/15/2023] [Accepted: 01/23/2023] [Indexed: 02/03/2023]
Abstract
Background: The role of medication-related osteonecrosis of the jaw (MRONJ) as a dento-maxillo-facial pathology is becoming increasingly important due to its growing prevalence. The success of preventive and therapeutic measures relies mainly on the dentist's ability to correctly diagnose the disease. Methods: The aim of this study was to evaluate the skills of dental students of different educational levels in choosing the correct stage, diagnostics, and treatment option for MRONJ based on clinical and radiographic imaging (panoramic radiograph, CBCT). The study was designed as a cross-sectional cohort study. Twenty dental students were asked to complete a questionnaire in their third and fifth year of studies in which they had to correctly stage the disease, choose the radiological diagnostics and recommend the treatment. The control group contained experienced oral and maxillofacial surgeons. Results: With an overall performance of 59% (third year: 145.2/248 points; fifth year: 145.3/248 points), no statistically significant difference between the educational levels could be observed. The classification based on CBCT imaging was significantly more often correct compared to panoramic radiographs (p < 0.001). Conclusions: This study highlights students' lack of knowledge in staging, diagnostics, and treatment of MRONJ, even though the CBCT positively affected decision-making. No significant increase in knowledge could be confirmed through clinical education. This study highlights the need for students to catch up on MRONJ diagnostics and treatment planning. Further expansion of teaching in this disease's context and X-ray diagnostics is needed.

Abstract
Objectives To assess the knowledge of medical doctors about osteonecrosis who prescribe radiotherapy and bisphosphonates and dentists who receive these patients with such risk factors. Methods This cross sectional multicenter study was carried out from 15th October 2021 to 20th November 2021 in different set-ups of Pakistan. A validated and piloted questionnaire was sent to dental and non-dental doctors working in different set-ups of Pakistan through email. All data was analyzed in SPSS version 22 with p value <0.05 being significant. Results A total of 400 completed responses were received. Only 58% and 67% of the participants were actively educating their patients regarding the hazards of bisphosphonate and radiotherapy, respectively whereas only 45% of the medical doctors referred their patients to dentists before prescribing bisphosphonates and/or radiotherapy. Although the medical doctors had a statistically better knowledge of the definition of osteonecrosis, overall both the dental and non-dental doctors performed poorly regarding answering the questions pertaining to definition, clinical features and risk factors. The dental doctors also showed a poor performance for more technical and in depth questions that was statistically related to lesser work experience, working in a tertiary care facility and previous exposure to such patients. Conclusion The inadequate awareness of dentists and physicians about the prevention and management of osteonecrosis of jaw is alarming. Efforts should be undertaken to raise the knowledge of dentists and physicians in this regard.

Abstract
Bone modifying agents (BMA) like bisphosphonates, antiangiogenic, and antiresorptive agents are widely used to manage bone diseases and cancer. Medication-related osteonecrosis of the jaw (MRONJ) is a potentially serious complication seen in patients on BMA therapy. Dental infection is one of the primary risk factors for MRONJ manifestation; hence its complete removal before initiation of BMA is significant. This can be achieved when a medical professional understands MRONJ and its risk factors and implements timely and regular dental referrals. This multicentre study was performed to assess the knowledge about MRONJ and awareness about the implementation of dental referrals among medical professionals. A custom-designed questionnaire tool was designed and validated by a pilot study. 450 practitioners from 6 medical schools and private practitioners in and around the district were surveyed. The results were analyzed using descriptive statistics. 63.5% (n=80) of the respondents prescribed bisphosphonates at a frequency of 0–5 times in a month. However, 62% (n=78) of the practitioners could correctly indicate the most appropriate definition of MRONJ. Only 49.2% (n=62) of them considered dental consultation mandatory. 73% (n=92) of the practitioners were unaware of management guidelines. There exists a significant gap in the knowledge-based applications in the management of MRONJ. Lack of referrals to dentists before BMA therapy can be a pivotal factor in patient morbidity. Practitioners prescribing BMA should advise patients about regular dental visits and monitor for symptoms of MRONJ.

Abstract
Objective This web-based survey, as a tool of teledentistry, is aimed at assessing the level of knowledge, attitudes, and awareness regarding MRONJ among dental professionals in Northern Cyprus. Methods An online self-administered questionnaire about MRONJ was sent to all dentists in Northern Cyprus through Google Forms. The first part of the questionnaire consists of demographic and professional information, and the second part included questions about knowledge and awareness questions about MRONJ. The SPSS software was used for statistical data analysis. A Chi-square test was performed to compare between the groups. The significance level was set at p < 0.05. Results A total of 112 dentists participated in this survey. The participants showed an insufficient level of knowledge regarding MRONJ, as only 56.6% of the participants stated that they had general knowledge about MRONJ. Regarding the practical questions of the survey, the participants showed poor knowledge about implant and tooth extraction procedures while a patient is using antiresorptive or antiangiogenic drugs, particularly the usage of oral antiresorptive or antiangiogenic drugs for less than 3 years. Participants showed adequate knowledge in terms of usage area of medications and administration of them. Conclusion Teledentistry can be used as a supportive tool for dentists in diagnosing MRONJ. Similar to previous studies, the knowledge and awareness of MRONJ of dentists in Northern Cyprus were found to be inadequate. There is a significant need to provide more professional information as part of undergraduate programs so that the next generation of dentists can practice more confidently.

Abstract
Medication-related osteonecrosis of the jaw (MRONJ) is a side effect of antiresorptive drugs. In this online survey, the awareness and knowledge of dentists regarding MRONJ was evaluated, and potential implications for oncologists are discussed. Questionnaires were emailed to dentists from Germany, Austria, Switzerland, and South Tyrol to evaluate disease-related knowledge and management. In addition to the overall score, a separate score was calculated for knowledge (maximum score: 15 points) and management (maximum score: 6 points) questions, and 1197 valid replies with completed questionnaires were received. The mean overall score was 10.45 ± 3.97 points, the mean knowledge score was 7.68 ± 3.05 points, and the mean management score was 2.76 ± 1.77 points. Factors influencing the outcome of the overall score were age, specialization, continuous professional education, and the number of dental screening exams in patients before antiresorptive therapy. Due to the considerable lack of knowledge regarding MRONJ among dentists, MRONJ patients and subjects at risk should be guided towards specialists for dental screening, treatment, and follow-up. This is important from an oncologic point of view to avoid any delay for treatment start of antiresorptives, and to reveal a potentially emerging osteonecrosis at an early stage, thus, avoiding the need for interruption or even cancellation of antiresorptive therapy.

Abstract
BACKGROUND Medication-related osteonecrosis of the jaw (MRONJ) is a severe side effect of bisphosphonates and anti-resorptive drugs prescribed for treatment of severe osteoporosis, Paget's disease, and bone malignancies. The aim of this study was to evaluate the clinical outcome of a combined pharmacological and surgical management strategy on patients affected by MRONJ. MATERIALS AND METHODS Medical records of patients with MRONJ were retrospectively examined to collect clinical history data. Conservative management included an initial pharmacological phase with antibiotics and antiseptic agents, followed by surgical intervention to remove bone sequestrum. Primary outcomes were healing from MRONJ at short term (1 month after surgery) and at longer term (3 months after surgery). Secondary outcome was assessment of recurrences at longer-term follow-up. RESULTS Thirty-five patients were included in the study with mean follow-up of 23.86 ± 18.14 months. Seven cases showed spontaneous exfoliation of necrotic bone during pharmacological therapy, which in one case did not require any further intervention. At 1-month posttreatment, 31 out of 35 (88.5%) patients showed complete healing. The 25 patients who were followed for at least 3 months revealed a healing rate of 92% (23/25). Recurrences occurred in 7 patients out 23 who showed the long-term healing, after a mean period of 7.29 ± 3.45 months. The prognostic score (University of Connecticut Osteonecrosis Numerical Scale-UCONNS) was significantly higher (p = 0.01) in patients with poor healing as compared to complete healing, both at 1 and 3 months posttreatment. CONCLUSIONS A MRONJ treatment approach based on a combined pharmacological and surgical treatment strategy showed a high rate of healing and few recurrences.
