What risk is associated with excessive heat generated during coronal polishing?

Excessive heat generated during coronal polishing poses a significant risk of damage to pulpal tissue or enamel. During the polishing process, if the instruments are improperly used or if excessive pressure is applied, it can create heat. This heat can elevate the temperature of the tooth structure to a point where it can lead to thermal injury. Enamel, while strong, can be compromised if subjected to high temperatures, potentially resulting in cracks, fractures, or even irreversible damage to the underlying dentin and pulp tissue. The pulp, being highly sensitive, is particularly vulnerable to heat, which can lead to inflammation or necrosis if the temperature exceeds safe levels. It’s essential for practitioners to apply appropriate techniques, ensuring that excessive heat is minimized during the procedure to prevent such damaging effects.
