Which clamp is identified as the right maxillary and left mandibular molar clamp?

The clamp identified as the right maxillary and left mandibular molar clamp is the 13A. This clamp is specifically designed to accommodate the anatomy of the molars in these positions, providing optimal retraction and stability during dental procedures.

The 13A clamp features specific angulations and sizes that allow it to fit securely around the maxillary right molar and the mandibular left molar, making it suitable for various restorative and endodontic treatments in these areas. Understanding the function and placement of this clamp is crucial for effective moisture control in dental work, ensuring that the operational field remains dry and accessible.

The other options, while they may refer to different clamps, do not provide the same anatomical fitting needed for this specific area of the mouth. Each clamp in dental practice has a unique design suited for certain teeth and jobs, and the 13A is particularly adapted for the needs of the specified molars.
