Impact of Chronic Kidney Disease Mineral and Bone Disorder on Jaw and Alveolar Bone Metabolism: A Narrative Review.

Chronic kidney disease (CKD) has become a worldwide public health problem. It is estimated that nearly 90% of patients with chronic renal failure manifest some symptoms of oral disease. With advances in medical treatment, CKD patients are living longer and require oral care. Chronic kidney disease is often accompanied by disturbances in mineral metabolism which are classified as their own clinical entity known as CKD-mineral and bone disorder (CKD-MBD). CKD-MBD affects all aspects of bone physiology: bone volume, bone turnover and bone mineralization. Jaw bones affected with CKD-MBD can have important clinical implications for the survival and osseointegration of dental implants, success of bone regeneration therapy, and increased risk of bone loss in patients with periodontitis or risk of bone fracture. Assessment of bone turnover is the most important diagnostic tool to monitor progression of CKD-MBD. Bone biomarkers and radiographical examination of bone density may be particularly useful to both, diagnosis and monitoring of bone turnover. Cone beam computed tomography (CBCT) as a reliable method with many advantages over other radiographic methods can be used for analysis of jaw bone micro-architectural changes and may be of a great help in bone quality determination in CKD-MBD.
