Abstract

Aim: Medication-related osteonecrosis of the jaw (MRONJ) challenges clinicians with its complex pathology and high risk of complications.

Methods: We searched seven databases - PubMed, Scopus, Web of Science, Cochrane Library, Embase, CINAHL, and Google Scholar - and adapted the search strings for each database to optimize retrieval of relevant studies. We then systematically reviewed the included studies to identify the most effective treatments for promoting MRONJ healing.

Results: A total of 329 records were identified through database searches across seven electronic databases. After removal of 45 duplicates, 284 records were screened. Following title and abstract screening and full-text assessment, 13 studies met the eligibility criteria and were included in the qualitative synthesis. The included studies consisted primarily of randomized controlled trials and retrospective cohort studies investigating surgical, pharmacological, and adjunctive therapeutic strategies for MRONJ management. Risk-of-bias assessment using the RoB 2.0 and ROBINS-I (Risk of Bias in Non-randomised Studies - of Interventions) tools showed that most studies presented low to moderate risk of bias, although some methodological concerns were identified. Surgical interventions were commonly associated with improved clinical healing, while adjunctive therapies such as bone morphogenetic protein-2 and teriparatide showed promising outcomes in selected cases. Follow-up periods ranged from 1 month to 2 years, and outcome measures included clinical, radiologicalal, and histologicalal evaluations.

Conclusion: MRONJ treatment is diverse and multifaceted. Such inferences were made to varying degrees in previous investigations, illustrating the limitations for clinical use, revealing the need for further studies to clarify both the efficacy and optimal use of the interventions in diverse clinical settings.

INTRODUCTION

Medication-related osteonecrosis of the jaw (MRONJ) has recently captured interest due to its increasing prevalence as well as its poorly defined etiology. It is an extremely disabling disorder that causes severe pain and is associated with impaired oral function in affected individuals[1,2]. It is commonly characterized as the exposed or necrotic jawbone, often due to long-term treatment by bisphosphonates, other antiresorptive agents, and anti-angiogenic drugs that are usually used for osteoporosis, malignancy, or rheumatoid arthritis[3]. MRONJ pathogenesis is multifactorial and mediated through a variety of molecular, cellular, and biomechanical mechanisms that disrupt the homeostatic integrity of bone and favor the formation of osteonecrotic lesions[4,5].

The mandible is highly sensitive to the pharmacodynamic actions of these medications as bone resorption is suppressed. Nevertheless, the precise etiology of MRONJ pathways continues to be unknown[6,7]. MRONJ typically presents with pain, inflammation, and bone exposure, which significantly affects quality of life and often requires aggressive surgical interventions[8].

Certain anatomical and physiological features make the jaw particularly prone to the negative impact of these drugs. This propensity is associated with the high vascularity and frequent bone remodeling of the alveolar process and periodontium, due to the mechanical stress of chewing[2,7]. MRONJ is thought to result from disturbances in bone remodeling, impaired angiogenesis, microtrauma, impaired immune function, or the presence of inflammation or infection[9].

The American Society for Bone and Mineral Research and the American Association of Oral and Maxillofacial Surgeons define MRONJ based on the following criteria: (i) current or prior treatment with antiresorptive or antiangiogenic agents; (ii) exposed or necrotic bone in the maxillofacial region persisting for more than eight weeks; (iii) no history of radiation therapy to the jaws; and (iv) absence of metastatic disease in the jawbones[2,10]. Treatment modalities should be individualized according to the stage of MRONJ, since early lesions may be managed conservatively, whereas surgery may be required for advanced lesions[11]. The duration of drug treatment and temporary interruptions (“drug holidays”) play an essential role in lesion management and healing[12]. MRONJ has four stages based on clinical features. Stage 0 includes non-exposed, prodromal disease, while stages 1 through 3 involve exposed bone, with or without infection, and increasing severity, including pathological fractures, fistulae, and osteolysis reaching the mandibular border or sinus floor[11-13]. Despite the lack of research into the pathogenesis, there are relatively few available evidence-based therapy indications for MRONJ[11,14]. The present systematic review presents the most recent evidence-based medical treatment approaches for MRONJ, focusing on the effectiveness of strategies aimed at regenerating bone and new tissue. Data from randomized controlled trials and observational studies were compiled to assess the effectiveness of interventions for promoting MRONJ healing using the Population, Exposure, Comparison, Outcome, Study Design (PECOS) framework.

METHODS

Eligibility criteria

The PECOS framework was developed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 reporting guidelines [Figure 1][15]:

• Population (P): Patients diagnosed with MRONJ at any stage (early, moderate and advanced).

• Exposure (E): Therapeutic interventions - surgical, pharmacological, or adjunctive - intended to promote bone healing and soft tissue regeneration in MRONJ.

• Comparator (C): Standard care, placebo, or alternative interventions.

• Outcome (O): Evidence of bone and soft tissue healing assessed through clinical, radiologicalal, and histologicalal outcomes, as well as measures of pain reduction and recurrence.

• Study design (S): Randomized controlled trials, non-randomized clinical trials, cohort studies, and case series with a minimum of ten patients.

Database search plan

A thorough systematic search was undertaken on seven databases: PubMed, Scopus, Web of Science, Cochrane Library, Embase, CINAHL, and Google Scholar. Google Scholar was included to retrieve grey literature and studies not indexed in the other databases, despite its limitations regarding the quality of literature. The search strategies employed MeSH terms [Table 2]. The search was limited to English-language publications published within the last 20 years (January 2005-January 2025) to ensure contemporary relevance and feasibility of analysis. The final literature search was completed on January 5, 2025.

Although grey literature was retrieved during the search process, it was excluded during the screening phase according to the predefined exclusion criteria.

Data extraction protocol

Both authors independently extracted data using a structured extraction form. Variables included study details (author, year, geographic location), participant information (sample size, age, gender), treatment modalities, MRONJ severity, treatment and follow-up period, evaluation methods (clinical, radiological, histological), and primary outcomes. Any discrepancies were resolved through discussion or referral to a third person. Cohen’s kappa was calculated to assess inter-rater reliability for study inclusion in this systematic review.

Bias analysis strategy

Risk of bias in non-randomized studies was assessed using the ROBINS-I (Risk Of Bias In Non-randomised Studies - of Interventions) tool[16], while the Cochrane's Risk of Bias 2 Tool (RoB 2) 2.0[17] was applied to randomized controlled trials. Two reviewers independently evaluated the risk of bias; disagreements were resolved through consensus or third-party adjudication. Inter-reviewer agreement, assessed using Cohen’s kappa, was 0.87, indicating strong concordance.

RESULTS

Trial inclusion process

In total 329 records were identified from database searches, and no records from the trial registries were found. After the elimination of 45 duplicate entries, 284 records remained for screening. After title and abstract screening, 250 articles were considered eligible for full-text assessment. However, 27 full-text articles could not be retrieved, leading to 223 studies considered eligible. The primary reasons for exclusion were studies not meeting PECOS criteria (n = 47), off-topic articles (n = 39), literature reviews (n = 42), scoping reviews (n = 33), and grey literature (n = 49). After applying all exclusion criteria, 13 studies[18-30] met the eligibility requirements and were included in the final analysis.

Assessed levels of bias

Risk of bias was classified as low, moderate, or high, based on the domain-specific criteria outlined in the Cochrane RoB 2.0 tool (for randomized trials) and the ROBINS-I tool (for non-randomized studies). Each domain - such as confounding (D1) and participant selection (D2) - was independently assessed by two reviewers, with the overall risk of bias determined by the highest level of concern in any domain.

Most studies[18,20,23,24,26] were rated as having a low overall risk of bias [Figure 2], while some[19,25,30] presented moderate concerns, and one study[28] was classified as having moderate risk of bias [Figure 3]. In detail, the studies by Freiberger et al.[18], Mozzati et al.[20], Park et al.[23], Poxleitner et al.[24], and Sahin et al.[26] showed a low risk of bias across all domains. Giudice et al.[19], Ristow et al.[25], and Yüce et al.[30] demonstrated concerns in multiple domains. Soutome et al.[28] had a moderate overall risk of bias, while Mücke et al.[21] exhibited a high risk specifically in domain D4, and Ohbayashi et al.[22] showed some concern in domain D5. Sim et al.[27] and Varoni et al.[29] demonstrated low risk in most domains, although minor concerns were noted in domains D5 and D7, respectively.

Baseline characteristics observed

Table 3 presents the trials included in this review[18-30] and their respective outcome assessments. The trials by Freiberger et al.[18] and Giudice et al.[19] had a slight majority of female participants, with 44%:56% and 42%:58%, respectively. In direct contrast, Mozzati et al.[20] reported marked imbalance, at 4%:96% and 2%:98% male:female (M:F) ratios for Protocols A and B, respectively. This marked gender imbalance could be due to the specific population sampled in that protocol (e.g., postmenopausal women with osteoporosis). Among the available data, Mücke et al.[21] included only male participants, and Ohbayashi et al.[22] included only female participants. Park et al.[23] reported an almost equal distribution: 57%:43%, and 43%:57% M:F in the Leukocyte- and Platelet-Rich Fibrin (L-PRF) and L-PRF + rhBMP-2 (recombinant human bone morphogenetic protein-2) groups, respectively. Poxleitner et al.[24] found a majority of females: 0%:100% and 3%:97% M:F in Groups A and B, respectively. The other studies presented various M:F ratios, ranging between 7:14 (reported by Sahin et al.[26]) and 53:47 (reported by Sim et al.[27]). Sample sizes differed between 13 participants in the study of Ohbayashi et al.[22] and 700 participants in the study of Mozzati et al.[20]. Most of the sample sizes included between 30 and 100 subjects.

Interventions and groups assessed

The study objectives differed: some focused on the prevention of MRONJ, including those conducted by Freiberger et al.[18], Mozzati et al.[20], Park et al.[23], Poxleitner et al.[24], and Sahin et al.[26]; whereas others - Giudice et al.[19], Mücke et al.[21], Ohbayashi et al.[22], Ristow et al.[25], Sim et al.[27], Soutome et al.[28], Varoni et al.[29], and Yüce et al.[30] - investigated treatment strategies for patients with MRONJ. With respect to study design, the majority were prospective randomized controlled trials (RCTs), including studies by Freiberger et al.[18], Mozzati et al.[20], Park et al.[23], Poxleitner et al.[24], Ristow et al.[25], and Sim et al.[27]; several were retrospective cohort studies, such as those by Giudice et al.[19], Ohbayashi et al.[22], Soutome et al.[28], and Varoni et al.[29]; and only one was a multicenter RCT, reported by Yüce et al.[30].

Interventions for MRONJ varied across studies. Hyperbaric oxygen (HBO) therapy was investigated in the study by Freiberger et al.[18], while platelet-rich fibrin (PRF) was evaluated in studies by Mozzati et al.[20], Park et al.[23], and Poxleitner et al.[24]. rhBMP-2 was also assessed in the study by Park et al.[23]. Surgical approaches were explored as well, including ultrasonic piezoelectric bone surgery, as reported by Sahin et al.[26], and segmental or marginal mandibulectomy, as in the study by Varoni et al.[29]. Control groups differed across studies: some used standard care, as reported by Freiberger et al.[18] and Mozzati et al.[20]; others employed placebo treatments, as reported by Sim et al.[27] and Yüce et al.[30]; in addition, non-PRF placement was used as a control in the study by Mozzati et al.[20], and no concentrated growth factor (CGF) placement served as the control in the work of Yüce et al.[30].

Results observed

The follow-up periods ranged from 1 month[28] to 2 years[18], with varying intervals in between. The outcome measures also differed across studies, reflecting the variations in objectives and interventions.

Freiberger et al.[18] reported a statistically significant improvement in the HBO group following treatment; 68% of patients improved, with a mean time to improvement of 39.7 weeks. Giudice et al.[19] found that the PRF group showed significant variations in mucosal integrity, absence of infection, and pain only at T1. Mozzati et al.[20] reported 100% success in both groups. Conversely, Mücke et al.[21] concluded that Group B showed a highly significant reduction in MRONJ incidence, with an observed risk of 82%.

Ohbayashi et al.[22] reported significant improvement in MRONJ stage for the daily teriparatide (TPTD) group. Park et al.[23] observed a significantly higher complete resolution rate in the L-PRF + rhBMP-2 group compared to the L-PRF group (75.2% vs. 48%, P = 0.028). Poxleitner et al.[24] reported no statistically significant between-group differences. Ristow et al.[25] reported successful healing in 100% of cases; however, two patients showed delayed healing.

Sahin et al.[26] demonstrated that a combined approach of surgical debridement and adjunctive teriparatide significantly improved bone healing in patients with MRONJ. Sim et al.[27] reported a complete healing rate of 55.3%, with poor outcomes influenced by platelet reactivity (PR) patterns. Soutome et al.[28] reported a long-term healing rate of 92%, though the recurrence rate was 30.4%. Varoni et al.[29] found no significant differences in postoperative healing between groups. For Yüce et al.[30], specific outcome measures were not clearly extractable.

DISCUSSION

Converging and diverging findings on MRONJ treatment strategies were observed during comparison with the included studies. As we see, surgical procedures are effective therapeutic approaches to MRONJ in numerous studies. Mozzati et al.[20] and Ristow et al.[25] presented consistent results, with Mozzati et al.[20] preferring Protocol B for less trauma to soft and hard tissues. Similarly, Sahin et al.[26] showed success using the surgical protocol for advanced MRONJ. Collectively, this would indicate that surgery may prove to be particularly beneficial in patients with high-stage MRONJ. Nevertheless, the modest sample sizes in these analyses limit the available evidence, and the need for larger, well-powered clinical trials is identified.

Another group of studies supports the use of adjunctive therapies to enhance MRONJ treatment outcomes. Park et al.[23] demonstrated an enhanced healing in the presence of bone morphogenetic protein 2 (BMP-2) and Sim et al.[27] also proposed that teriparatide, possibly used as an effective therapeutic agent, may be potentially useful in MRONJ treatment. These findings imply that adjunctive therapy with adjuvant therapies such as BMP-2 and teriparatide can also be effective in increasing success rates in the treatment of MRONJ. However, Yüce et al.[30] identified no benefit from CGF, thus, the effect of adjunctive treatments may be based on patient characteristics, disease stage or treatment protocol.

In contrast, in numerous studies, outcomes suggested findings that varied from most others. Freiberger et al.[18] suggested that HBO treatment could serve as a promising adjunct to, or alternative for, surgical approaches in MRONJ. Giudice et al.[19] stated that PRF enhanced immediate healing while long-term efficacy of PRF compared to other treatments has not yet been established. Finally, Mücke et al.[21] demonstrated that antibiotic prophylaxis combined with tension-free wound closure significantly decreased MRONJ incidence. Similar preventive approaches were also investigated in studies by Poxleitner et al.[24] and Yüce et al.[30], although their results were more heterogeneous.

Notably, Yüce et al.[30] found that CGF did not significantly improve soft tissue repair in MRONJ, a result that contradicts the findings from other adjunctive therapies. These results may have limited generalizability, as they are specific to the patient population and clinical setting of the study. Ohbayashi et al.[22] and Varoni et al.[29] presented results which are difficult to directly compare, and looked at novel treatments including daily teriparatide treatment, with combined pharmacological-surgical protocols, respectively. Several non-randomized studies showed moderate to high risk of bias, leading to caution in translation to clinical practice.

Studies by Mozzati et al.[20], Ristow et al.[25], and Sahin et al.[26] share a common focus on evaluating the effectiveness of surgical interventions in treating MRONJ. Similarly, Park et al.[23] and Sim et al.[27] both investigated the role of adjuvant therapies - BMP-2 and teriparatide, respectively - in MRONJ treatment. The remaining studies varied considerably in design and focus, examining diverse methods for both prevention and treatment of MRONJ.

In cases of early-stage MRONJ, patients are often asymptomatic with minimal bone exposure and conservative/noninvasive treatment protocols have been proposed as a reasonable alternative[2]. The problem is that these patients are often poor candidates for long-term antibiotic use due to advanced age, previous prolonged chemotherapy regimens, or metastatic bone disease. While local or systemic antibiotic therapy may alleviate symptoms, this relief is often short-lived; recurrences occur on average every three weeks[31], leading researchers to seek alternative treatment modalities. Conservative management might alleviate the symptoms and infections in the short run, but one must not forget that osteonecrosis is not going to be cured by these methods[32]. However, if there is exposed necrotic bone, then conservative management fails because the bone tissue is dead and therefore can never be restored to its former state.

The decision to discontinue medications prior to surgical intervention for MRONJ remains a topic of debate[33]. A recent systematic review and meta-analysis found that patients with multiple myeloma or osteoporosis who underwent a "drug holiday" from alendronate, ibandronate, or zoledronate exhibited a higher prevalence of complete recovery[34]. On the other hand, some researchers argue that withdrawal of these drugs is unnecessary due to the long half-life of bisphosphonates (approximately 11 years), which are sequestered in bone hydroxyapatite crystals. There is also a concern that drug discontinuation may exacerbate underlying conditions, such as bone pain or skeletal weakness.

Similar to our findings, Beth-Tasdogan et al.[35] conducted a systematic review to assess interventions for the prophylaxis and treatment of MRONJ. Including only RCTs, however, they made the conclusion that the certainty of existing evidence was low or very low. Our review demonstrated this and found that evidence for MRONJ interventions remains limited and of low quality. Similarly, Kawahara et al.[36] described a systematic literature review to produce updated recommendations for dental treatment which would be directed to avoid the onset of MRONJ. Their findings emphasized the importance of producing clinical guidelines from scientific evidence; they mirrored our own findings that high-quality evidence is a requisite for clinical practice.

Kuroshima et al.[37] conducted this review to summarize the current knowledge and theories on MRONJ from clinical perspective and basic science perspective. The study included MRONJ definition, epidemiology, causative drugs, histopathology, and pathophysiology. Likewise, our work explored MRONJ epidemiology, pathophysiology and risk factors. Similarly, AlRowis et al.[38] performed a review of the literature to identify diagnostic criteria and risk factors of MRONJ. They also discussed its pathophysiology, preventive methods, and treatments. Their review had covered the commonality across epidemiology, diagnostic criteria, risk factors, pathogenesis and therapeutic management. As there is high heterogeneity in interventions and outcome measures as well as follow-up periods across the included studies, a meta-analysis was not possible and a qualitative assessment was thus conducted solely.

Limitations

Our results should be interpreted in the context of several limitations. Variability in study design and population may have contributed to heterogeneity in the findings, limiting the ability to perform a meta-analysis. Moreover, only a few studies were available investigating specific interventions such as add-on therapies, which could limit the extent to which the findings can be generalized. Publication bias is also a consideration as this review is based entirely on published literature. Similarly, there were limitations with respect to differences in follow-up periods and outcome measures, but both were included to prevent a significant loss of the body of available literature.

Clinical recommendations

Based on our findings, several recommendations were made for managing MRONJ. Oral surgeons, oncologists and other health professionals must take a comprehensive multidisciplinary approach to ensure optimal treatment outcomes. For the more advanced stages of MRONJ, surgical procedures such as debridement and resection are indicated. Prophylactic measures should be properly defined, with tension-free wound closure. Adjuvants are shown to possess promising therapeutic potential, especially bone morphogenetic protein-2 and teriparatide. Care must be tailored to patients' individual disease stage and history. Finally, future research will need to determine more definitively the degree to which these interventions are both effective and best implemented depending on the clinical case and also to formulate evidence-based guidelines in managing MRONJ.

CONCLUSION

Based on this review, surgical interventions appear most successful for advanced-stage MRONJ, while BMP-2 and teriparatide have shown efficacy in promoting healing in some cases. Prophylactic measures, such as antibiotics and tension-free wound closure, may reduce the risk of MRONJ in high-risk populations. However, well-designed, multicenter studies are needed to establish optimal treatment protocols for the various stages of MRONJ.
