Granulation tissue removal after extracting a lower left first premolar requires which instrument?

Granulation tissue removal after an extraction procedure is typically facilitated using a Mitchell trimmer. This particular instrument is designed with a sharp cutting edge that allows for precise and controlled removal of granulation tissue in the alveolar bone and surrounding tissues after a tooth extraction. The design of the Mitchell trimmer enables dental professionals to effectively contour soft tissue and remove the granulation without damaging adjacent structures.

Other instruments like the periosteal elevator, surgical bur and handpiece, and tissue dissection forceps have their specific uses in dental procedures but are not primarily used for the targeted task of granulation tissue removal. The periosteal elevator is mainly employed for elevating and reflecting the periosteum from the bone, while surgical burs are used for cutting hard tissue. Tissue dissection forceps can grasp and manipulate tissues but are not as effective for the specific need of cutting or trimming granulation tissue. Therefore, the Mitchell trimmer is the most suitable instrument for this task due to its specific design and intended purpose in dental procedures.
