  2. Pulp necrosis - Wikipedia

    en.wikipedia.org/wiki/Pulp_necrosis

    Pulp necrosis is a clinical diagnostic category indicating the death of cells and tissues in the pulp chamber of a tooth with or without bacterial invasion. [1] It is often the result of many cases of dental trauma, caries and irreversible pulpitis.

  3. Periapical granuloma - Wikipedia

    en.wikipedia.org/wiki/Periapical_granuloma

    Periapical granuloma, [1] also sometimes referred to as a radicular granuloma or apical granuloma, is an inflammation at the tip of a dead (nonvital) tooth. It is a lesion or mass that typically starts out as an epithelial lined cyst, and undergoes an inward curvature that results in inflammation of granulation tissue at the root tips of a dead tooth.

  4. Medication-related osteonecrosis of the jaw - Wikipedia

    en.wikipedia.org/wiki/Medication-related_osteo...

    Tooth extraction is the major risk factor for development of MRONJ. Prevention including the maintenance of good oral hygiene, comprehensive dental examination and dental treatment including extraction of teeth of poor prognosis and dentoalveolar surgery should completed prior to commencing any medication which is likely to cause osteonecrosis ...

  5. Periapical cyst - Wikipedia

    en.wikipedia.org/wiki/Periapical_cyst

    Secondary [clarification needed] symptoms of periapical cysts include inflammation and infection of the pulp causing dental caries. This infection is what causes necrosis of the pulp. [4] Larger cysts may cause bone expansion or displace roots. Discoloration of the affected tooth may also occur.

  6. Pulpitis - Wikipedia

    en.wikipedia.org/wiki/Pulpitis

    Pulpitis can often create so much pressure on the tooth nerve that the individual will have trouble locating the source of the pain, confusing it with neighboring teeth, called referred pain. The pulp cavity inherently provides the body with an immune system response challenge, which makes it very difficult for a bacterial infection to be ...

  7. Condensing osteitis - Wikipedia

    en.wikipedia.org/wiki/Condensing_osteitis

    Condensing osteitis happens when the bone around the tooth reacts to long-term inflammation. This involves excessive bone growth, leading to the formation of sclerotic bone in the jaw. Ongoing tooth infections, like pulpitis, release chemicals that attract immune cells and activate osteoblasts. Osteoblasts create extra bone in response to ...

  8. Pulp (tooth) - Wikipedia

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

    As the dental pulp is a highly vascularised and innervated region of the tooth, it is the site of origin for most pain-related sensations. [12] The dental pulp nerve is innervated by one of the trigeminal nerves, otherwise known as the fifth cranial nerve. The neurons enter the pulp cavity through the apical foramen and branch off to form the ...

  9. Neuralgia-inducing cavitational osteonecrosis - Wikipedia

    en.wikipedia.org/wiki/Neuralgia-inducing_cavitat...

    In NICO the pain is said to result from the degenerating nerve ("neuralagia"). [2] [3] [1] The condition is probably rare, if it does exist. [4] Also called Ratner's bone cavity, a neuralgia-inducing cavitational osteonecrosis was first described in dental literature by G V Black in 1920. [5]
