Toothache may be caused by dental (odontogenic) conditions (such as those involving the dentin-pulp complex or periodontium), or by non-dental (non-odontogenic) conditions (such as maxillary sinusitis or angina pectoris). There are many possible non-dental causes, but the vast majority of toothache is dental in origin. [10]
Threshold shift can also cause threshold pressure to vary. [4] Prolonged exposure to sound at levels evoking pain can cause physical damage, potentially leading to hearing impairment and tinnitus. The volume in acoustics refers to loudness. It is a common term for the amplitude of sound or the sound pressure level.
The trigeminal nerve.. ATN is usually attributed to inflammation or demyelination, with increased sensitivity of the trigeminal nerve.These effects are believed to be caused by infection, demyelinating diseases, or compression of the trigeminal nerve (by an impinging vein or artery, a tumor, dental trauma, accidents, or arteriovenous malformation) and are often confused with dental problems.
Capsaicin causes reversible degeneration of epidermal nerve fibers. [55] Notably the capsaicin used for the relief of neuropathic pain is a substantially higher concentration than capsaicin creams available over the counter, there is no evidence that over the counter capsaicin cream can improve neuropathic pain [ 56 ] and topical capsaicin can ...
Excluding an organic cause for the pain is the most important part of the diagnosis. Odontogenic pain should especially be ruled out, since this accounts for over 95% of cases of orofacial pain. [8] There is considerable symptom overlap between atypical facial pain and temporomandibular joint dysfunction. [12]
Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).
Inflammation is one common cause that results in the sensitization of nociceptors. Normally hyperalgesia ceases when inflammation goes down, however, sometimes genetic defects and/or repeated injury can result in allodynia: a completely non-noxious stimulus like light touch causes extreme pain. Allodynia can also be caused when a nociceptor is ...
Glossopharyngeal neuralgia, a rare disorder, usually begins after age 40 and occurs more often in men. Often, its cause is unknown. However, glossopharyngeal neuralgia sometimes results from an abnormally positioned artery that compresses the glossopharyngeal nerve near where it exits the brain stem. Rarely, the cause is a tumor in the brain or ...
