Shear bond strength of two adhesives to bovine dentin contaminated with various astringents.

Purpose: To investigate the in vitro shear bond strength of two adhesives to bovine dentin contaminated with various astringents.

Methods: 120 adult bovine incisors were collected and cut to obtain 240 specimens. The specimens were randomly divided into a self-etch adhesive group (N = 120) and a total-etch adhesive group (N = 120).

Psychosocial sequelae and correlates of orofacial injury.

Orofacial injury is a condition that disproportionately affects disadvantaged minorities--particularly young men--with great personal and health care consequences. Beyond the overt physical injury, a large proportion of the presenting patients manifest acute psychological sequelae. Although many patients may recover, in a sizeable proportion the symptoms may persist for extended periods of time and prove to be an obstacle to rehabilitation and reintegration.
