Medication-related osteonecrosis of the jaw (MRONJ) is a rare but severe complication of anti-resorptive drugs. This review explores why the jawbone is uniquely susceptible to MRONJ, unlike other skeletal sites.
Area of Science:
- Oral and Maxillofacial Surgery
- Pharmacology
- Bone Biology
Background:
- Medication-related osteonecrosis of the jaw (MRONJ) is a serious adverse effect of anti-resorptive medications.
- Despite systemic drug effects, MRONJ predominantly affects the jawbones.
- Current understanding of MRONJ pathogenesis and prevention strategies remains limited.
Purpose of the Study:
- To investigate the unique susceptibility of the jawbone to MRONJ.
- To explore the multifactorial pathogenesis of MRONJ.
- To identify potential new directions for MRONJ prevention and treatment.
Main Methods:
- Literature review and synthesis of existing research on MRONJ.
- Analysis of the unique characteristics of the oral microenvironment.
- Comparative study of bone metabolism in the jaw versus other skeletal sites.
Main Results:
- The jawbone's unique anatomical and physiological features may predispose it to MRONJ.
- Specific factors within the oral microenvironment contribute to MRONJ development.
- Understanding these unique factors is crucial for targeted prevention and management.
Conclusions:
- The jawbone's distinct susceptibility to MRONJ warrants further investigation.
- Targeting the oral microenvironment may offer novel strategies for MRONJ prevention.
- Further research into the multifactorial pathogenesis of MRONJ is essential.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
