The correct approach when placing a rubber dam clamp is to seat the lingual jaws of the clamp first. This method is essential for ensuring that the clamp is positioned securely and effectively. By starting with the lingual jaws, the assistant can better control the placement, as this allows for a stable foundation before the facial jaws are seated.

Seating the lingual jaws first helps to establish proper alignment with the tooth and reduces the likelihood of the clamp slipping or causing discomfort to the patient. This approach also enables the assistant to monitor the clamp’s position relative to the tooth, which is crucial for maintaining optimal isolation of the working area during procedures.

In contrast, focusing on the facial jaws first could lead to complications such as misalignment or inadequate retention of the clamp. Additionally, aligning the clamp with the occlusal plane and applying the rubber dam before the clamp are steps that can either follow or be integrated into the process but are secondary to securing the positioning of the clamp itself.
