Ultra HD Liposuction: Enhancing Abdominal Etching Using Ultrasound-Guided Rectus Abdominis Fat Transfer (UGRAFT).

Unlabelled: High-definition (HD) liposuction has allowed surgeons to sculpt the abdomen, enhancing abdominal etching. To create a more athletic abdomen, fat grafting has been used subcutaneously, and rectus abdominis fat grafting has been performed in patients undergoing lipoabdominoplasty. With the objective of increasing muscle volume to obtain a natural-looking abdomen in patients who are not suitable for abdominoplasty, we propose the use of ultrasound-guided rectus abdominis fat grafting (UGRAFT) in association with HD liposuction.

Ion release from a composite resin after exposure to different 10% carbamide peroxide bleaching agents.

Objective: This in vitro study evaluated the influence of two 10% carbamide peroxide bleaching agents - a commercial product (Opalescence PF; Ultradent Products, Inc.) and a bleaching agent prepared in a compounding pharmacy - on the chemical degradation of a light-activated composite resin by determining its release of ions before and after exposure to the agents.

Material And Methods: Thirty composite resin (Filtek Z250; 3M/ESPE) samples were divided into three groups: group I (exposed to Opalescence PF commercial bleaching agent), group II (exposed to a compounded bleaching agent) and group III (control - Milli-Q water).
