What type of polishing is used for root surfaces exposed during periodontal surgery?

Therapeutic polishing is specifically designed to be used on root surfaces that have been exposed during periodontal surgery. This method focuses on smoothing and cleaning the roots to promote healing and reduce the potential for bacteria to accumulate, which can contribute to infection or further periodontal issues. The polishing helps in removing any surface irregularities and deposits on the root surfaces, which is crucial for the successful healing of the gum tissues around the teeth.

Preventive polishing typically aims to maintain oral health and prevent disease by cleaning and polishing teeth with no specific therapeutic intent, while cosmetic polishing is more concerned with enhancing the aesthetic appearance of the teeth rather than addressing underlying health issues. Electro-polishing, though a method of polishing, is not commonly used in dental practices and is not particularly suited for the delicate needs of root surfaces exposed in periodontal surgery.

Therefore, therapeutic polishing is the most appropriate choice for caring for exposed root surfaces post-surgery, emphasizing healing and health over aesthetics or routine maintenance.
