Since phase changes generally result in dimensional changes, the temperatures at which the phase changes occur in waxes and the influence of adding one wax to another are important in understanding the behavior of waxes. Differential thermal analysis (DTA) offers a useful tool in the study of phase transitions. This study examines the temperature of phase transitions for various commercial, den...

Rhesus monkeys were trained to criterion on a two-stimulus and a fivestimulus pattern discrimination task. The probabilities of response to the various stimuli throughout learning are examined for individual subjects, and it is fOlL'1d that the subjects exhibit consistency in the order and manner in which incorrect stimuli are eliminated. This suggests a simple mathematical description of the p...

Case description: The patient of this case report presented 2 pairs of equivalent cervical abfraction lesions, under occlusion. Four restorations were placed in teeth 34, 35, 44 and 45. The restorations were divided into groups (Single Bond + Filtek-Flow + Filtek Z250 or Single Bond + Filtek Z250) and the materials were applied according to the manufactures instructions. Two previously calibrat...
