Keys to Bonding Esthetic, Durable Zirconia Restorations: Two Case Reports.

Polycrystalline metal oxide-based ceramics, typically referred to as zirconium dioxide (or zirconia), have advanced greatly in the past two decades, becoming a popular cosmetic restorative material. Although contrary to common belief, adhesive bonding to zirconia is not only possible but quite effective using the right materials with proper technique. This article discusses keys to bonding to zirconia, presenting two case reports in which adhesion and cementation are demonstrated.

Optimizing shade match using all-ceramic and composite materials.

Aesthetic management of the anterior dentition often requires the restorative team to use materials of varying color properties. The utilization of shade-selection devices to assist in color interpretation along with dental photography can improve communication between dentist and technician. Additionally, a shade guide system that addresses the four components of color in both ceramics and composites can have a profound impact on the predictability of matching different restorative materials.

Use of a numeric visual analog anxiety scale among patients undergoing colorectal surgery.

The aim of this study was to evaluate the utility of a Numeric Visual Analog Anxiety Scale (NVAAS) as a potentially accurate and efficient way to determine presurgery anxiety among patients undergoing colorectal surgery. A secondary aim was to determine the relationship between NVAAS ratings of anxiety and postsurgery pain. Thirty-six patients scheduled for colorectal surgery were asked to rate their state anxiety on the NVAAS and to complete the State-Trait Anxiety Inventory (STAI).
