When a tooth has necrosis octopus His color changes from white to dark. necrosis usually has two causes: first and most common is infectious (caries), second is traumatic.
The tooth inside contains a neurovascular package located at a root duct that leads to a chamber (pulp) in the crown. If the neurovascular package suffers a necrosy assault and this necrosis results from dark tooth color That can range from dark yellowish to brown or even grey.
The treatment of the black tooth starts with a careful clinical and radiographic examination. It's necessary to determine if the tooth's replaceable and that's why the root should be complete.
If the cause of the discolouration is a profound caries It's necessary to look at the depth of the caries and to determine if it's compromising the root. If the root is complete or if the caries aren't situated under the level of the bone under the gums, the tooth will be restored. The first step will be the elimination of an infectious lesion by a endodontics That's the cleanup of the root duct and the polished chamber and its subsequent hermetic shutting. Following an anti-infectious phase, an aesthetic restorative phase should be performed with a Porcelain carilla or crown Depending on the degree of destruction of the dental crown.
On the other hand if the origin of the discolouration is a trauma dental carewe have to investigate the presence of a radicular fracture or fissure. If the root is integrated, the same endodontics and restoration protocol as described above should be followed.
If there are either of these (radicular fracture or fissure) the tooth isn't replaceable. It should be noted that a microphysiure is a space that will always be colonized by microorganisms and will always give signs and symptoms of infection (pain, fistula, abscesses) and so treatment should be required in this case to remove and replace the dental part with a prothesis that can be supported (Porcelain fixed bridge) or supported implant (dental implant).
