What shape should the end of the Coe-Pak strip be bent into for proper placement?

The end of the Coe-Pak strip should be bent into a hook shape for proper placement. This design allows the strip to be effectively manipulated and positioned during periodontal procedures, such as in the reinforcement and stabilization of periodontal dressings.

The hook shape facilitates the secure attachment to soft tissues, providing better retention and support to the area being treated. This configuration helps in anchoring the dressing effectively, which is crucial in maintaining the operative site, minimizing displacement, and promoting healing.

In contrast, other shapes like a circle, loop, or triangle may not provide the same level of stability or may be challenging to apply, leading to potential issues with dressing retention and effectiveness. The hook allows for a practical and functional approach in the dental surgical context where precision and stability are paramount for successful outcomes.
