When inverting the Dental Dam, how should the inverter be positioned relative to the tooth?

When inverting the Dental Dam, positioning the inverter perpendicular to the tooth is essential for achieving an effective seal. This vertical orientation allows the dam to tuck into the sulcus properly, creating a barrier that prevents moisture from contaminating the working area. A perpendicular approach facilitates better access and manipulation, ensuring that the material is adequately forced into the crevices without risking damage to the tooth structure or surrounding tissues.

Other orientations, such as parallel or diagonal, do not provide the same level of effectiveness in sealing. A horizontal approach also fails to ensure the dam is secured tightly against the tooth, making it less effective at moisture control. Proper technique during the inversion process is critical for maintaining a dry operating field and achieving successful dental procedures.
