Extraction of permanent teeth

29 Extraction of permanent teeth


A thorough oral and dental examination, including investigating periodontal parameters, was performed. All findings were noted on the dental record sheet.

In summary, examination under general anaesthesia identified the following list:

Careful examination with a sharp explorer did not allow communication into the pulp.


Malocclusion can result from jaw length and/or width discrepancy (skeletal malocclusion), from tooth malpositioning (dental malocclusion), or a combination of both. This case is a skeletal malocclusion and should therefore be considered as inheritable. Malocclusion causing discomfort and pathology always needs treating.

The treatment options available are orthodontics, tooth shortening or extraction. In many instances, tooth shortening or extraction are preferable to orthodontics on ethical grounds.

In human orthodontics, whether malocclusion is hereditary or acquired is not a consideration when planning treatment. This is in contrast to veterinary orthodontics, where aesthetics and ethical concerns are linked, and treatment for the sole purpose of showing dogs or cats cannot be encouraged. The aim of any treatment is primarily to make the animal comfortable; aesthetics are a secondary consideration.

It is essential to determine if the presenting malocclusion is hereditary or not. Orthodontic correction of a malocclusion is contraindicated where the malocclusion is hereditary, unless the animal is also neutered. The rationale for this is to avoid spread of inherited malocclusion within a breed.

Crown fractures are classified as complicated if the fracture line exposes the pulp to the oral environment and as uncomplicated if they do not involve pulpal exposure. Crown fractures are obvious visually. However, at times it can be difficult to determine if the pulp is exposed by the fracture line, and general anaesthesia for examination with a dental explorer and radiography are necessary.

An uncomplicated crown fracture usually requires minimal treatment, e.g. removal of sharp edges with a bur and sealing of the exposed dentine with a suitable liner or restorative material. However, such fractures do require monitoring (clinical examination and radiography) at regular intervals to ensure that the pulp remains vital. If pulp and periapical diseases develop, the tooth requires either extraction or endodontic therapy.
