What is a common cause of injury during tooth preparation?

In the context of tooth preparation, the use of coolant during the drilling process is crucial to prevent injury to both the tooth and the surrounding periodontal tissues. When coolant is not utilized, the heat generated from the friction of the drill can lead to thermal injury. This elevated temperature can damage the pulp of the tooth and potentially cause irreversible pulpitis or necrosis. Additionally, it may also lead to discomfort for the patient and affect the quality of the tooth preparation.

Using adequate coolant helps in maintaining a suitable temperature, ensuring a smooth and safe preparation process. It minimizes the risk of complications related to heat, supporting the health and integrity of the tooth being treated. Inadequate coolant usage is, therefore, a significant risk factor associated with injuries during tooth preparation.
