What is Dental Avulsion?
Dental avulsion is a common dental emergency that can happen as a result of trauma or impact to the mouth. If left untreated, avulsed teeth can cause severe damage to the roots and nerves within the socket.
Treatment for avulsed teeth depends on several factors, including the age at the time of injury and the degree of jaw growth. The longer the avulsed tooth has been out of the mouth, the worse the prognosis.
Knocked Out Tooth
A knocked out tooth is an avulsed tooth (meaning the root of the tooth has been dislodged). Knocked out teeth often happen during sports injuries and fights.
The tooth may fall out completely, or the roots can be crushed or scraped away from the socket. This can damage the root surface or cause infection of the socket, which can lead to loss of the tooth if not treated. This is why it is important to act immediately and replant the tooth into the socket. Knocked out teeth often happen during sports injuries and fights.
Trauma
Avulsed teeth are a common dental emergency and should be treated as quickly as possible. To remove nerve tissue from the tooth, and to avoid infection.
The International Association of Dental Traumatology (IADT) has developed guidelines to help healthcare providers provide the best possible care in a timely manner. The guidelines are based on the latest literature research and professional opinion.
The avulsed tooth should be stored in a physiologic storage medium with osmolality balanced. Examples of osmolality-balanced media are milk or Hanks’ Balanced Salt Solution (HBSS). The avulsed tooth should be agitated in the storage medium to remove gross debris from its surface.
Replanting the Tooth
Accidents, altercations and contact sports are the most common sources of traumatic dental injuries (TDIs). These injuries include avulsed teeth, which are completely dislodged from their sockets. A tooth that is replanted within 30 minutes to an hour has the highest chance of survival.
The prognosis of avulsed permanent teeth depends on the time between injury and treatment. A tooth that is replanted within 30 minutes to an hour has the highest chance of survival.
Treatment Options
Dental avulsion is one of the most common traumatic injuries to the permanent dentition, with incidences ranging from 1-16% of all traumatic injuries. Failure to wear a mouthguard during sporting activities. Replantation also prevents ankylosis of the alveolar bone and increases the chance of maintaining the height of the alveolar bone ridge.
It has been shown that immediate replantation of an avulsed tooth is the best treatment option. As well as the patient’s rate of alveolar growth. Failure to wear a mouthguard during sporting activities (Hedegard et al, 1973). As well as the patient’s rate of alveolar growth.
Dry storage of avulsed teeth results in death of PDL cells, which can lead to root resorption and ankylosis. Replantation with an appropriate storage medium (Hanks’ balanced salt solution, saline or milk) re-establishes viable periodontal ligament cells. As well as the patient’s rate of alveolar growth.
Replantation also prevents ankylosis of the alveolar bone and increases the chance of maintaining the height of the alveolar bone ridge. Which allows for a more esthetically pleasing prosthetic rehabilitation in the future. The prognosis depends on the initial condition of the avulsed tooth. As well as the patient’s rate of alveolar growth.
