[Relationship between Occlusal Discomfort Syndrome and Occlusal Threshold].
Summary
Patients with occlusal discomfort syndrome (ODS) experience a lower threshold for discomfort when sensing occlusal changes. This simple test can help evaluate their perceptive abilities.
Area of Science:
- Dentistry
- Sensory Perception
- Biomedical Engineering
Context:
- Occlusal dysesthesia, known as "Occlusal discomfort syndrome" (ODS) in Japan, presents persistent discomfort after dental interventions without physical discrepancies.
- Current treatments for ODS often yield unsatisfactory results for both patients and dental professionals.
Purpose:
- To investigate the characteristics of ODS by examining occlusal sensory perceptive and discriminative abilities.
- To differentiate ODS patients from healthy controls using a simple occlusal sensory test.
Summary:
- A study compared 21 ODS patients with 21 controls using occlusal registration foils to determine recognition and discomfort thresholds.
- ODS patients exhibited a significantly lower discomfort threshold compared to controls, while recognition thresholds did not differ.
- Age-dependent increases in recognition thresholds were observed in controls but not in ODS patients.
Impact:
- The findings suggest that the occlusal discomfort threshold, not the recognition threshold, is a key factor in ODS.
- A simple foil grinding test can effectively evaluate occlusal perceptive and discriminative abilities in ODS patients.
- This research may lead to improved diagnostic methods and targeted treatments for ODS.

01:25Analgesia 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...

1.7K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

01:21Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

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.

01:03Olfactory Receptors: Location and Structure
13.7K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

01:29Blood 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...
