Study Notes

Pulpal Diseases and Their Characteristics

Inflammation will reverse and the pulp will return to its normal state if the cause is eliminated
Pathogenesis of acute pulpitis involves vascular dilation leading to increased vascular permeability and fluid exudate
Examination and diagnosis of acute pulpitis involves visual signs like caries or recent trauma, as well as specific symptoms and sensitivity tests
Treatment for acute pulpitis includes root canal treatment (RCT) in advanced stages
Differential diagnosis between reversible and irreversible pulpitis involves the presence and depth of caries, as well as the nature of pain
Chronic pulpitis is an inflammatory response of the pulp resulting from long-term, low-grade injury
Chronic closed pulpitis presents with intermittent dull aching pain and less sensitivity to heat and cold
Chronic open ulcerative pulpitis symptoms range from non-existent to minimal, with dull pain exacerbated by thermal changes
Chronic open hyperplastic pulpitis (pulp polyp) occurs in molar teeth of children and young adults, presenting as a painless red or pinkish soft nodule
Additional pulpal diseases include hyperemia, necrosis, retrogressive pulp changes, internal resorption, and previously treated tooth
Necrosis is the death of the pulp and can be classified as liquefactive or coagulative, with different pathogenesis and examination findings
Retrogressive pulp changes include atrophy, defined as a decrease in size, and typically requires root canal treatment

Pulpoperiapical Pathosis Classification and Treatment

Overinstrumentation can lead to inaccurate measurement of the R.C length
Improper manipulation includes pushing chemicals or toxic material into the surrounding periapical tissue
Incomplete removal of pulp tissue can result in infected remnants extending to the periapical area
Pulpoperiapical pathosis is classified into symptomatic and asymptomatic categories
Symptomatic pulpoperiapical disease is characterized by an inflammatory response of the periapical C.T.
Acute apical periodontitis (incipient stage) presents with moderate to severe pain, localized pain, and increased pain on percussion
Treatment for acute apical periodontitis (incipient stage) involves root canal treatment
Acute apical periodontitis (advanced stage) includes features such as throbbing pain and acute periapical abscess
Acute periapical abscess is an advanced exudative and severe symptomatic inflammatory response of periapical C.T.
Recrudescent abscess (Phoenix abscess) is an acute exacerbation of a chronic lesion
Subacute periapical abscess is a painful phase of a chronic periapical abscess cycle
Asymptomatic pulpoperiapical pathosis is characterized by a chronic apical periodontitis, which may result from pulp necrosis or an acute apical periodontitis that has dissipated
