The posterior intravaginal slingplasty operation: results of the Austrian registry.

Objective: We set up a registry to assess complications and short-term results of the posterior intravaginal slingplasty operation.

Study Design: A total of 14 gynecology departments in Austria completed questionnaires addressing the patient's history, the operation itself and the postoperative course. In the follow-up we asked for information on tape exposure and functional and anatomical results.

Influence of bleaching agents and desensitizing varnishes on the water content of dentin.

This in vitro study investigated the possible dehydration of dentin caused by bleaching agents. Furthermore, it tested whether protective dentin varnishes can maintain the physiological moisture of dentin during bleaching treatment. Fifty-five standardized dentin cylinders were prepared from freshly extracted bovine incisors under constant water irrigation.
