The present study showed a rate of 48% of positivity in nasal biopsy of untreated patients, correlating well with skin biopsy and skin smear. Thus, the method in leprosy diagnosis and clinical form classification has shown great reliability.

were proposed to characterize the surface energy of real implants: a qualitative method related to the phenomenon of capillarity and a quantitative method with different liquids of known surface tension. It was found that the topography of the thread flanks is considerably different from the topography of the discs and it is believed that the geometry of the implant influences the surface treatment. The proposed quantitative methodology to analyze the surface energy allowed to detect differences between two commercial implants tested.

The aim of this study was to analyze the effect of the separation of prosthetic crowns from fixed partial dentures by means of stress gradient evaluation. Three photoelastic models were created to examine contiguous implants with varying contact between the crowns (contact point [CP], contact surface [CS], splinted [SP]). The SP group presented the best results, followed by the CS group, indicating that the use of splinted prosthetic crowns and crowns with broad surface contacts is viable when considering the stress values.
