ABSTRACT
What I have tried to do is to provide a way that we can look at overall recruitment and retention of our minority students. As you can see from the results of the survey, some of us are doing a lot, some not so much. About 10% of the colleges have many of the components of retention suggested within this schema. Some of us are seeing results of our efforts--with many of us reporting that the attrition of minority students is equal to less than that of majority students--yet many of us feel that much more can be done to improve the total environment for our minority students. You will recall the word used the most in your responses, "more", more of nearly everything. I am sure you join with me in looking forward to the presentations during our conference so that we may find ways to increase our efforts. We do not want in the future for either us or our students to again sound like Oliver Twist when he pleaded "Please Sir, I want some more".

The bond strength of visible light-activated composites to etched enamel was measured as a function of exposure time. Studies have shown that the bottom surface may not be as hard as the top after customary cure times. Therefore this study also measured hardness and related it to enamel bonding. Plexiglas molds were used to simulate extracoronal applications where light is not attenuated by enamel. Bond strength and hardness of the bottom surfaces reached maximum values after the same exposure times with two of the three composites. More exposure time than normally recommended by manufacturers was needed to obtain maximum bond strength to enamel.

A method has been described in which light-activated resins are incorporated into the dental anatomy laboratory. This procedure is a valuable addition to the anatomy course because students (1) work with a restorative material appropriate for anterior teeth, (2) learn the unique properties of the light-activated resins, and (3) apply the principles of dental anatomy to a clinically relevant task.

The strength of bonding of dental composites to enamel was measured in shear. The compressive strength, proportional limit, elastic modulus, and tensile strength of the composites were measured for correlation with the bond strength. Conventional and microfilled composites with a range of filler concentrations were studied. The densities of the composites and their fillers and the concentrations of the fillers were determined. The mechanical properties that were most highly correlated with bond strength to enamel were proportional limit and elastic modulus. Tensile strength and filler concentration had lower correlation coefficients, and compressive strength was not correlated with bond strength. Using unfilled resins as bonding agents between the composites and enamel resulted in increased bond strength with half of the composites.

Laminate denture teeth that effectively cover stained anterior teeth must be placed carefully so that bond strength is optimal, gingival tissues are healthy, and major problems are avoided. A method of placement is described step by step.
