The BES EndoApp is a web-based case difficulty assessment tool designed to help assess the risks and difficulties of a particular case that requires non-surgical endodontic treatment.

It was developed from the original version of EndoApp*.

The algorithm takes into account various tooth and patient factors relevant to the complexity of a case. A score is generated which suggests the most appropriate management route. The user can then decide as to whether to manage the case or refer onwards.

The BES EndoApp is compatible on both desktop and mobile devices. Please follow the link below ‘BES EndoApp’ or QR code and choose to ‘Bookmark’ or ‘Add to Home screen’ for easier access.
