Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Taste Buds and Receptors01:20

Taste Buds and Receptors

Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia

Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
Tooth Anatomy01:21

Tooth 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 grinding food.
Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation01:21

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Summary

Occlusal dysesthesia (OD) is poorly understood, often misdiagnosed. Research suggests it involves altered central processing, not just teeth issues, highlighting the need for better diagnosis and management strategies.

Area of Science:

  • Dental Research
  • Neurology
  • Psychology

Background:

  • Occlusal dysesthesia (OD) presents as persistent discomfort without clear dental causes.
  • This condition is poorly understood, leading to frequent misdiagnosis and inconsistent treatment.
  • Despite clinical recognition, the underlying mechanisms of OD remain elusive.

Purpose of the Study:

  • To comprehensively review the literature on occlusal dysesthesia.
  • Identify existing knowledge gaps in its conceptualization and mechanisms.
  • Propose research priorities for improved understanding and clinical care.

Main Methods:

  • A scoping review adhering to Joanna Briggs Institute guidelines.
  • Searched seven databases for English-language publications from 1976 to 2026.
  • Included diverse sources like clinical studies, case reports, and reviews; two reviewers screened all records.

Main Results:

  • Forty-six articles were included, predominantly non-empirical reports, with most clinical studies from Japan.
  • Psychophysical tests showed no altered occlusal discrimination, but psychological distress and depression were common.
  • Limited neuroimaging indicated altered central processing, especially in prefrontal areas; no validated diagnostic criteria or management strategies exist.

Conclusions:

  • OD is likely a heterogeneous condition involving central processing and perception alterations, not solely occlusal abnormalities.
  • Urgent need for multidisciplinary research integrating psychophysics, psychological assessment, and neuroimaging.
  • Future research should inform evidence-based diagnosis and management for occlusal dysesthesia.
