Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Bone Remodeling01:40

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Peptic Ulcer Disease III: Clinical Manifestations and Complications

Duodenal UlcersDuodenal ulcers are the most common form of peptic ulcer disease, presenting with chronic, intermittent epigastric pain. Pain typically appears 2–3 hours after meals, especially when the stomach is empty, often waking patients at night. It is characteristically relieved by food or antacids (“pain–food–relief”). Some patients remain asymptomatic until complications like bleeding or perforation emerge, particularly with NSAID or anticoagulant use.Gastric UlcersGastric ulcers share...

Summary

Patients with multiple systemic conditions taking bisphosphonates face increased risks of complications, including osteonecrosis of the jaw (ONJ). Careful management by a specialist team is crucial for these patients undergoing dental procedures.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Oncology
  • Internal Medicine

Background:

  • Bisphosphonate-associated osteonecrosis of the jaw (ONJ) is a serious complication.
  • Multiple systemic conditions can exacerbate ONJ risks and complications.

Purpose of the Study:

  • To highlight the increased risk of complications in patients with systemic diseases and ONJ.
  • To emphasize the need for specialized dental management in these complex cases.

Main Methods:

  • A case report detailing mandibular necrosis in a patient with complex systemic conditions on oral bisphosphonates.

Main Results:

  • Systemic conditions and multiple medications (e.g., bisphosphonates, antithrombotics) can impair tissue healing.
  • Bisphosphonate use exceeding three years correlates with increased ONJ risk in complex systemic situations.

Conclusions:

  • Oral surgery can be contraindicated or require significant modification in patients with certain systemic diseases.
  • Multidisciplinary specialist collaboration is essential for managing patients on bisphosphonates with complex systemic conditions during all surgical phases.
