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 .
Pulp necrosis usually occurs either as ischaemic necrosis (infarction) caused by disruption to the blood supply at the apical foramen or as an infection-related liquefactive necrosis following dental trauma (2). Signs of pulpal necrosis include [42] Persistent grey colour to tooth that does not fade; Radiographic signs of periapical ...
Necrotizing sialometaplasia (NS) is a benign, ulcerative lesion, usually located towards the back of the hard palate.It is thought to be caused by ischemic necrosis (death of tissue due to lack of blood supply) of minor salivary glands in response to trauma.
b) Pulp Necrosis: The pulp tissue dies as a result of untreated pulpitis or direct trauma. Tooth discoloration; Infection: If bacteria penetrate the dentin and reach the pulp, it can lead to abscess formation or other periapical (around the root tip) infections. This can result in swelling, pain, and possible tooth loss if left untreated.
The pulp is still alive, but the introduction of bacteria into the pulp will not allow the pulp to heal and it will ultimately result in necrosis, or death, of the pulp tissue. [ 11 ] Symptoms associated with irreversible pulpitis may include dull aching, pain from hot or cold (though cold may actually provide relief) lingering pain after ...
Inflammation therefore increases pressure in the pulp system, potentially compressing the blood vessels which supply the pulp. This may lead to ischemia (lack of oxygen) and necrosis (tissue death). Pulpitis is termed reversible when the inflamed pulp is capable of returning to a state of health, and irreversible when pulp necrosis is inevitable.
What they look like: Chiggers, a type of small mite, typically leave clusters of bites that are often very itchy. In many cases, chigger bites appear as small, red and itchy bumps. Sometimes, they ...
Cracked tooth syndrome could be considered a type of dental trauma and also one of the possible causes of dental pain.One definition of cracked tooth syndrome is "a fracture plane of unknown depth and direction passing through tooth structure that, if not already involving, may progress to communicate with the pulp and/or periodontal ligament."
