Characteristics and dimensions of the infraorbital canal: a radiographic analysis using cone beam computed tomography (CBCT).

Purpose: To analyze morphological characteristics and dimensions of the infraorbital canal-groove complex using cone beam computed tomography (CBCT), and to evaluate its relationship with adjacent anatomical structures.

Methods: This retrospective study included CBCT scans of 100 patients taken between January and May 2014. Linear measurements of the infraorbital canal (IOC), the infraorbital groove (IOG) and the infraorbital canal-groove complex (IOC/G) were performed.

Validation of a purpose-built chewing gum and smartphone application to evaluate chewing efficiency.

Objectives: To validate a purpose-built two-coloured chewing gum (Hue-Check Gum ), and to test the accuracy of a custom-built smartphone application for a colour-mixing ability test to assess chewing function.

Methods: Fully dentate participants (28D-group) and edentulous participants with implant overdentures (IOD-group) were recruited. They chewed a Hue-Check Gum for 5, 10, 20, 30 and 50 chewing cycles, respectively.
