  2. Pulp necrosis - Wikipedia

    en.wikipedia.org/wiki/Pulp_necrosis

    Pulpitis is stated to be one of the stages of disease progression which leads to pulpal necrosis. This inflammation can be reversible or irreversible. Due to the enclosed nature of the pulp chamber - unlike normal inflammation - when inflamed, the increased pressure cannot be displaced to other tissues, resulting in pressure on the nerve of ...

  3. Pulpitis - Wikipedia

    en.wikipedia.org/wiki/Pulpitis

    With a reversible pulpitis, sleep is usually not affected and no analgesics are necessary. Usually, no atypical change is evident on the radiograph. [4] Pulp vitality tests are positive and it is possible to preserve a healthy vital pulp. Irreversible pulpitis, in contrast, is characterised by a constant severe pain that arises without provocation.

  4. Pulp (tooth) - Wikipedia

    en.wikipedia.org/wiki/Pulp_(tooth)

    Pulpitis is established when the pulp chamber is compromised by bacterial infection. Irreversible pulpitis is diagnosed when the pulp is inflamed and infected beyond healing. Removal of the aetiological agent does not permit healing, and a root canal is often indicated. Irreversible pulpitis follows reversible pulpitis absent early intervention.

  5. Toothache - Wikipedia

    en.wikipedia.org/wiki/Toothache

    Pulpitis is reversible when the pain is mild to moderate and lasts for a short time after a stimulus (for instance cold); or irreversible when the pain is severe, spontaneous, and lasts a long time after a stimulus. Left untreated, pulpitis may become irreversible, then progress to pulp necrosis (death of the pulp) and apical periodontitis ...

  6. Second law of thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Second_law_of_thermodynamics

    For any irreversible process, since entropy is a state function, we can always connect the initial and terminal states with an imaginary reversible process and integrating on that path to calculate the difference in entropy. Now reverse the reversible process and combine it with the said irreversible process.

  7. Irreversible process - Wikipedia

    en.wikipedia.org/wiki/Irreversible_process

    An irreversible process increases the total entropy of the system and its surroundings. The second law of thermodynamics can be used to determine whether a hypothetical process is reversible or not. Intuitively, a process is reversible if there is no dissipation. For example, Joule expansion is irreversible because initially the system is not ...

  8. Pulp capping - Wikipedia

    en.wikipedia.org/wiki/Pulp_capping

    Exposure of the pulp causes pulpitis (an inflammation which can become irreversible, leading to pain and pulp necrosis, and necessitating either root canal treatment or extraction). [1] The ultimate goal of pulp capping or stepwise caries removal is to protect a healthy (or reversibly inflammed) dental pulp, and avoid the need for root canal ...

  9. Dental pulp test - Wikipedia

    en.wikipedia.org/wiki/Dental_pulp_test

    Dental pulpal testing is a clinical and diagnostic aid used in dentistry to help establish the health of the dental pulp within the pulp chamber and root canals of a tooth. . Such investigations are important in aiding dentists in devising a treatment plan for the tooth being test
