Analgesia and Pain Management01:25

Analgesia and Pain Management

2.7K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Nociception01:44

Nociception

34.0K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

14.5K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Summary
This summary is machine-generated.

Directly extracting third molars with acute pulpitis causes more postoperative pain than delayed extraction or removing healthy third molars. Managing pulpitis before extraction reduces pain.

Area of Science:

  • Dentistry
  • Oral Surgery

Background:

  • Third molar extraction is common.
  • Acute pulpitis can complicate third molar removal.
  • Postoperative pain is a significant concern.

Purpose of the Study:

  • To investigate the relationship between acute pulpitis and postoperative pain following third molar extraction.
  • To compare pain levels after direct extraction versus delayed extraction (following endodontic treatment) of third molars with acute pulpitis.
  • To compare pain levels with the extraction of third molars without pulpitis.

Main Methods:

  • Randomized controlled trial involving 90 patients requiring maxillary third molar extraction.
  • Group A (n=30): Direct extraction of third molars with acute pulpitis.
  • Group B (n=30): Endodontic therapy followed by extraction 24 hours later.
  • Group C (n=30): Direct extraction of third molars without caries or acute pulpitis.

Main Results:

  • Significant pain difference between direct extraction of inflamed molars (Group A) and delayed extraction (Group B) on days 1-3 post-surgery.
  • Significant pain difference between direct extraction of inflamed molars (Group A) and extraction of healthy molars (Group C) on days 1-3 post-surgery.
  • No significant pain difference between delayed extraction of inflamed molars (Group B) and extraction of healthy molars (Group C) on days 1-3 post-surgery.

Conclusions:

  • Directly extracting third molars with acute pulpitis results in higher postoperative pain.
  • Endodontic treatment prior to extraction can mitigate postoperative pain associated with acute pulpitis.
  • Managing pulpitis before third molar extraction is recommended to reduce patient discomfort.
