Final answer:
Rosin is used in periodontal dressing to increase adherence, which helps the dressing stay in place, protecting the wound and aiding in healing after periodontal surgery.
Step-by-step explanation:
The purpose of using rosin in periodontal dressing is to increase the dressing's adherence and thus stabilize the dressing. Rosin is a natural resin that provides stickiness to the dressing, ensuring it stays in place after periodontal surgery. It helps maintain the dressing's position over the wound, protecting it from external irritants and reducing postoperative discomfort.
Rosin in the periodontal dressing plays a crucial role by acting as a physical barrier, and its adhesive properties maintain the dressing's position to aid in healing. It also provides support for the newly formed tissue and shields it against trauma during the initial healing phase. Using rosin in dental dressings is a standard practice for improving patient outcomes after periodontal interventions.
