Considerations for proper selection of dental cements.

Selecting the proper cement for sufficient bond strength has become progressively complicated as the number of different materials for indirect restorations has increased. The success of any restoration is highly dependent on the proper cement being chosen and used. The function of the cement is not only to seal the restoration on the tooth but also, in some cases, to support the retention of the restoration.

Computer assisted learning: a new paradigm in dental education.

Computer assisted simulation is an important teaching modality in the preclinical training of students. In order to maximize the potential of this learning tool, the University of Tennessee's College of Dentistry has successfully incorporated DentSim technology into the restorative curriculum and has recently acquired the technology to make image guided implantology available to students, residents and faculty. This article describes the university's history and experience with simulation as a learning tool.

Variations in the mechanical properties of Alouatta palliata molar enamel.

Teeth have provided insights into many topics including primate diet, paleobiology, and evolution, due to the fact that they are largely composed of inorganic materials and may remain intact long after an animal is deceased. Previous studies have reported that the mechanical properties, chemistry, and microstructure of human enamel vary with location. This study uses nanoindentation to map out the mechanical properties of Alouatta palliata molar enamel on an axial cross-section of an unworn permanent third molar, a worn permanent first molar, and a worn deciduous first molar.

Comparison of centering pregnancy to traditional care in Hispanic mothers.

Objective: To compare maternal and infant outcomes in Hispanic women participating in the Centering Pregnancy Model (CPM) to those receiving prenatal care via the traditional model and determine acceptability of the CPM.

Methods: Forty-nine women (n = 24 CPM; n = 25 traditional) participated in this quasi-experimental prospective comparative design. Participants self selected the model of care delivery.
