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. It is often the end result of many cases of dental trauma, caries and irreversible pulpitis. In the initial stage of the infection, the pulp chamber is partially necrosed for a period of time and if left untreated, the area of cell death expands until the entire pulp necroses. The most common clinical signs present in a tooth with a necrosed pulp would be a grey discoloration of the crown and/or periapical radiolucency.

This procedure is required if there is a damage to the bone chain of the middle ear. Commonly affected bone is the long process of incus, where it gets necrosed. The bone chain can be repaired using autograft of incus or cartilage. Prosthetic implants made of titanium, hydroxyapatite or teflon are also used.

Definitive surgical treatment involves anatomical repositioning of the stomach and spleen followed by a right-sided gastropexy. Depending on the severity, partial gastrectomy and/or splenectomy may be indicated if the relevant tissues have necrosed due to ischemia caused by torsion/avulsion of the supplying vasculature. 72-hour post-operative supportive care, fluid therapy and ECG monitoring for cardiac arrhythmias is highly recommended.

Radiographically a radiolucent area within the root canal may be visible and/or the canal may appear sclerosed. Chronic pulpal inflammation is thought to be a cause of internal resorption. The pulp must be vital below the area of resorption to provide osteoclasts with nutrients. If the pulp becomes totally necrosed the resorption will cease unless lateral canals are present to supply osteoclasts with nutrients.

Riggs was an opponent of periodontal surgery, which at the time consisted of gingival resection. He promoted the concept of proper oral hygiene and prevention. Riggs first demonstrated his method of conventional periodontal therapy in 1856: he removed salivary and serumal deposits and necrosed bone from the teeth with scrapers that he designed. He then applied a tincture of powdered myrrh and polished the teeth.

The pain associated with pulp necrosis is often described as spontaneous. Hot temperatures are reported to have exacerbating factors, and cold temperatures are said to soothe this pain. In some cases, the pain presents as a long dull ache as this is due to necrosis of the apical nerves being the last part of the pulp to necrose. Therefore the pain is from the apical nerves, which have residual vitality remaining when the majority of the pulp is necrosed due to the supply of blood to the more medial parts of the apical nerve.

The pulse oximeter test is a more accurate way to test for necrotic pulps as it primarily tests for vascular health of the pulp as compared to its nervous response. This method involves taking measurements of blood oxygen saturation levels, making it non-invasive and an objective way to record patient response regarding pulpal diagnosis. In a study conducted in primary and immature permanent teeth, results clearly reflected that pulse oximetry can readily differentiate between vital and non-vital, necrosed teeth. The pulse oximeter consists of a probe containing 2 light-emitting diodes, one of which transmits red light to measure the absorption of oxygenated haemoglobin, and the other transmitting infrared light, measuring the absorption of deoxygenated haemoglobin.
