Endo Glossary Flashcards
abscess
localised colllection of pus within a tissue space
access cavity
opening prepared in a tooth to gain access to the root canal system for the purpose of cleaning, shaping and obturating
accessory canal
any branch of the main pulp canal or chamber that communicates with the external surface of the root
acute apical abscess
inflammatory reaction to pulpal infection and necrosis characterised by rapid onset, spontaneous pain, tenderness of tooth to pressure, pus formation and swelling of associated tissues
allodynia
pain resulting form a non-noxious stimulus to normal skin or mucosa
anaesthetic test
special investigation in which a tooth suspected of being the source of referred pain is anaesthetised with LA, if the pain is alleviated the suspected tooth may be the source of the pain
anatomic apex
tip of the root as determined by morphology
apex
tip/end of root
apex locator
an electronic device used as an aid in determining the root canal working length or perforation; operates on the principles of resistance, frequency or impedance
apexification
method to induce a calcified barrier in a root with an open apex or the continued apical development of an incompletely formed root in teeth with necrotic pulps
apexogenesis
vital pulp therapy procedure performed to encourage continued physiological development and formation of the root end
apical constriction
apical portion of the root canal having narrowest diameter; position may vary but it is usually 0.5-1.0mm short of the centre of the apical foramen
apical delta
pulp canal morphology in which the main canal divides into multiple accessory canals at or near the apex
apical gauging
measurement of the terminal diameter or shape of a canal after the initial crown-down shaping
apical patency (patency filing)
technique where the apical portion of the canal is maintained free of debris by instrumentation with a small file through apical foramen
apicetomy
see root-end resection
asymptomatic apical periodontitis
inflammation and destruction of apical periodontium that is of pulpal origin, appears as an apical radiolucent area and does not produce clinical symtoms
atypical odontalgia (phantom tooth pain)
pain with all the classic features of pulpagia usually following an extraction but not appearing to be of peripheral origin
austenitic phase
crystalline unstressed phase of stainless steel and nickel titanium alloy
backfiling
injection and/or compaction of GP into canal after creation of apical seal
balanced force technique
technique for cleaning and shaping the root canal system that allows opposing physical forces to guide each preparation instrument; uses clockwise rotation to engage dentine and counter-clockwise rotation whilst maintaining apical pressure to cut dentine
baradontalgia
tooth pain caused by a change in ambient pressure, often reported whilst flying or diving
bifurcation
anatomic area where roots of 2 rooted teeth divide
bioceramic
group of bioactive ceramic materials that are biocompatible with good physical and chemical properties used in endodontics as pulp capping or root end filing materials
