Causes and risk factors
Periodontal ligaments are the ligaments which surround the tooth and it functions in holding the tooth in its socket. It is due to this ligament that there remains a distance between the tooth and the bone. In dental ankylosis due to a bony bridge, the ligament is obliterated. As a result, the root of the tooth fuses with the alveolar bone. Dental ankylosis is commonly seen in some of the members of the same family. Studies have shown that certain genetic factors are also responsible for this condition. Trauma and infection are some of the other contributing factors.
Clinical presentation:
Dental ankylosis can affect the primary as well as permanent tooth. In cases where the primary tooth is affected, it can hamper the growth of the permanent tooth. It reduces the space needed for the permanent tooth to erupt. It also affects the development of the jaw, thus reducing the jaw height.
Investigations:
The complaints narrated by the patient are taken into consideration. Clinical examination alone is carried out by the dentist. Tapping of the root is carried out. An oral x-ray may be done.
Treatment:
The main aim of the treatment is to ensure the growth of the permanent tooth. Surgical intervention is the main line of treatment. Removal of the ankylosed tooth is recommended.
