An erosion test for dental cements.

A new method for the in vitro measurement of the erosion of dental cements is described which allows repeated, gentle removal of loose surface debris and provides a direct quantitative measurement of material lost. A linear relationship for erosion against time is demonstrated for a glass polyalkenoate material under mildly acidic conditions. This test method is applicable to all acid/base-type cements and gives results comparable to those from in vivo tests.

The bond strength of composite laminate veneers.

An in vitro model has been developed simulating a composite laminate veneer restoration, along with methods to mimic the environmental conditions to which these restorations are subjected in vivo. Fifty composite laminate specimens were prepared: Ten were left untreated as controls, and 40 were exposed to simulated environmental conditioning. The tensile bond strength of the veneer-to-composite interface was significantly reduced by both thermal and humidity cycling, which may explain the increasing prevalence of marginal failure and staining which occurs as these restorations age in vivo.
