Pathophysiology theories

Hey Lesion, received a response back from an endo colleague regarding the etiology of the pain after asking if it was a mild pulpitis,

“

No ! Dentinal sensitivity is the branstrom theory of fluid movement inside the Dentinal tubules and that causes firing if the nerves ending in the outer layer of the pulp. Theoricly[sic] pulp is healthy. Now repetitive and constant stimulus can be etiology for a future pulpitis. Check.[sic] Bramstron

”

With that info, I found a review at pubmed pmid 22238734. Will also post to talk:Toothache Ian Furst (talk) 11:31, 21 December 2013 (UTC)[reply]

Yes, this is what I was finding in the sources too. E.g.:

“

Majority of literature reviews dealing with this clinical condition [...] consider that the sharp pain is actually the normal pulpal response to the exposed dentine.[1]

”

Therefore, I disagree with placing content about dentin hypersensitivity in a section called "pulpitis". If all pulpal causes of toothache to be merged into one section, it cannot be called "pulpitis" for accuracy... suggest "pulpal" instead. Lesion (talk) 12:15, 21 December 2013 (UTC)[reply]

Regarding reference 10 ( Schmidlin, Patrick R.; Sahrmann, Phlipp (30 December 2012). "Current management of dentin hypersensitivity". Clinical Oral Investigations 17 (S1): 55–59. doi:10.1007/s00784-012-0912-0.), I don't see how that article shows abrasive toothpaste contributes to the problem. — Preceding unsigned comment added by 32.217.10.85 (talk) 16:48, 29 August 2014 (UTC)[reply]

Not looked at the source in question, but abrasive toothpastes are a recognized cause of sensitvity. They cause tooth wear (technically, abrasion) with loss of tooth substance and resultant loss of thickness of enamel which "insulates" the dentin-pulp complex against stimulae. 92.40.94.197 (talk) 18:33, 29 August 2014 (UTC)[reply]
