Perception of esthetic orthodontic appliances: .

Objective: To evaluate the perception of esthetic orthodontic appliances by means of eye-tracking measurements and survey investigation.

Materials And Methods: En face and close-up images with different orthodontic appliances (aligner appliance [a], aligner appliance and attachments [b], lingual appliance [c], ceramic brackets [d], no appliance [e; control]) were shown to 140 participants. Eye movement and gaze direction was recorded by eye-tracking system.

A new flash-free orthodontic adhesive system: A first clinical and stereomicroscopic study.

Objective: To analyze the clinical and laboratory properties of the recently introduced APC flash-free orthodontic adhesive.

Material And Methods: After bonding of 80 brackets on human teeth (group A: APC flash-free adhesive n  =  40, group B: APC Plus adhesive n  =  40), the following measurements were recorded: time for bonding, stereomicroscopic evaluation of excess adhesive, color penetration (methylene blue, 0.5%/24 h), and Adhesive Remnant Index (ARI) score after debonding.
