For easy removal, the diagonal slot of the Tofflemire should be directed towards which area?

The diagonal slot of the Tofflemire retainer should be directed towards the gingival area to facilitate the easy removal of the matrix band after the restoration process. When placed this way, the orientation allows for better access to the matrix band during removal without disturbing the restoration or the surrounding dental structures.

Positioning the diagonal slot towards the gingival area minimizes the chance of tearing or damaging the band when it is removed. The gingival direction provides the best leverage for pulling the band out smoothly, ensuring a clean removal that does not disrupt the dental work just completed.

Choosing locations such as the buccal, incisal, or lingual would hinder proper removal, potentially complicating the process by making it more difficult to access the band and risking damage to the restoration and surrounding tissues.
