Summary
The prevalence of torus mandibularis in hemodialysis patients is 7.8%. Younger age and higher blood phosphate levels are significant predictors for torus mandibularis in this population.
Area of Science:
- Oral Medicine
- Nephrology
- Public Health
Background:
- Limited data exists on torus mandibularis prevalence in dialysis patients.
- Oral manifestations are common in hyperparathyroidism and uremia.
- Uremia may influence facial bone structure changes.
Purpose of the Study:
- To determine the prevalence of torus mandibularis in hemodialysis patients.
- To identify risk factors associated with torus mandibularis in this cohort.
Main Methods:
- Prospective observational study of 322 hemodialysis patients.
- Clinical oral examinations including inspection and palpation.
- Multivariate logistic regression analysis to identify predictors.
Main Results:
- Prevalence of torus mandibularis was 7.8%.
- Mandibular tori were typically symmetric, nodular, <2cm, and in the premolar area.
- Higher blood phosphate and younger age were significant predictors (p<0.05).
Conclusions:
- Torus mandibularis affects a notable percentage of hemodialysis patients.
- Blood phosphate levels and patient age are key factors associated with its occurrence.
- Further research into the oral health of dialysis patients is warranted.

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

288
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

01:25Hemodialysis I: Introduction
449
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

919
Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
