What is the primary function of the #301 root elevator during tooth extraction?

The primary function of the #301 root elevator during tooth extraction is to expand the alveolus and sever the periodontal ligament. This instrument is specifically designed to aid in the process of tooth extraction by exerting leverage on the tooth. By expanding the alveolar bone, the elevator facilitates the loosening of the tooth from its socket, making it easier to remove. Severing the periodontal ligament, which attaches the tooth to the bone, is a critical step in ensuring that the tooth is detached properly for extraction.

Understanding the role of the #301 root elevator emphasizes its importance in the extraction procedure. This tool allows the dentist to perform the procedure with precision, minimizing trauma to the surrounding tissue and improving efficacy in removing the tooth without unnecessary complications.
