Across-sectional survey on medication-related osteonecrosis of the jaws' knowledge and awareness in a sample of dental society

Anti-resorptive therapy and MRONJ. A survey of the Italian Society of Periodontology and Implantology

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.

Teledentistry as a Supportive Tool for Dentists in Diagnosing MRONJ in Northern Cyprus

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.

Knowledge, Attitude, and Management of General Dentist toward Medication-related Osteonecrosis of the Jaws

Background:

Medication-related osteonecrosis of the jaw (MRONJ) is an intense negative drug response causing increasing bone destruction in the maxillofacial area of patients.

Aims and Objectives:

To evaluate the knowledge and attitude of dental practitioner regarding risk factors of MRONJ in Saudi Arabia.

Materials and Methods:

A cross-sectional, questionnaire survey was carried out in King Khalid Hospital, Al-Kharj among dental practioners.

Results:

Approximately 60% of the practioners had a poor knowledge and there was a weak positive correlation with work experience.

Conclusion:

Poor knowledge regarding the MRONJ invites a continuing dental education specially to focus on general practioners.

Awareness of the risk of developing medication-related osteonecrosis of the jaw among bisphosphonate users

Objective

In this retrospective observational study, we evaluated awareness among patients using bisphosphonates (BPs) regarding the risk of developing medication-related osteonecrosis of the jaw (MRONJ) and whether they received appropriate dental screening and treatment prior to commencing medication.

Methods

Patients using BPs who attended the endodontics clinic at Jordan University Hospital in 2019 were interviewed using a pre-designed questionnaire. Data were analysed using descriptive statistics and chi-squared tests.

Results

In total, 110 patients were interviewed (84 women, 26 men; age 40–78 years). A total of 94 patients were using oral BP and 16 received intravenous (IV) BP. We found that only 12.4% of participants were aware about the risk of MRONJ following BP use, and only one third of them has received information from their prescribing physicians. In total, 5% of participants were referred to a dentist for screening prior to initiating BP treatment. Patients receiving IV BP and those with a university-level education had better awareness about the risk of MRONJ than oral BP users and those with a high school education level.

Conclusion

Patients’ awareness about MRONJ risk was low in our population. Better patient education and collaboration among physicians and dentists are needed prior to starting BP treatment.

Current knowledge regarding medication-related osteonecrosis of the jaw among different health professionals

PURPOSE

To assess the current knowledge regarding medication-related osteonecrosis of the jaw (MRONJ); the adverse effects of anti-resorptive (AR) and anti-angiogenic (AA) drugs; strategies for MRONJ prevention and treatment; and perception of the dentist's role in assisting patients who use these drugs among physicians, dentists, and nurses.

METHODS

Using questionnaires, the current knowledge of MRONJ was assessed among dentists, physicians, and nurses, who were divided into group I, which included specialties that directly assist cancer patients, and group II, which included other specialties. The questionnaires assessed the characteristics of the health professionals, training time, and specialties; their knowledge of AR and AA drugs; and their knowledge of MRONJ.

RESULTS

A total of 1370 health professionals participated in the study, including 1032 dentists, 239 physicians, and 99 nurses. Among dentists and physicians, the training time (p = 0.036 and p < 0.001, respectively) and specialization in group I domains (p < 0.001 and p < 0.001, respectively) had a significant impact on MRONJ knowledge, while nurses showed no significant impact regardless of the training time and specialty. Less than 10% of the physicians and dentists could correlate the signs and symptoms of all stages of MRONJ.

CONCLUSION

The findings indicated a notable lack of knowledge regarding MRONJ among dental surgeons and physicians, and especially among nurses. More experienced professionals and specialists in the areas that assist cancer patients usually have a greater understanding of the dentist's role in MRONJ prevention, diagnosis, treatment, and patient care and will introduce or are already using AR and AA drugs.

Medical students' knowledge of medication related osteonecrosis of the jaw

INTRODUCTION

The objective of this study was to assess medical students' knowledge of "medication related osteonecrosis of the jaws" (MRONJ).

METHODS

A questionnaire survey was administered to all the medical students in the last two years of school of medicine at the University of Eastern Piedmont between January 2019 and March 2019. The questionnaire contained a first section regarding demographic and personal data of the student and a second section regarding the knowledge on MRONJ.

RESULTS

On the whole, 72 medical students agreed to participate to this study and filled in the questionnaire. As for indications for the use of bisphosphonates 45 students correctly answered "osteoporosis, osteogenesis imperfecta, multiple myeloma, or metastasis of some malignant tumors". Almost all students (71 out of 72) answered that a thorough examination of oral cavity and a dentist screening is needed and fundamental before starting bisphosphonate assumption. As for drugs responsible for MRONJ, only 12 students out of 72 correctly answered "bisphosphonates, denosumab, and antiangiogenic drugs".

DISCUSSION

A better level of knowledge and awareness by medical doctors and young physicians may lead, in future, to minimize incidence of MRONJ as well as to a better resolution of ONJ cases. Theoretical and practical initiatives could be promoted to improve and consolidate the knowledge of future physicians about this important issue.
