PURPOSE To assess whether the amount of residual coronal dentin and the placement of a prefabricated (DT Light Post) (LP) or a customized fiber post (Ever Stick Post) (ES) have a significant influence on the 3-year survival of endodontically treated premolars. METHODS A sample of 345 patients provided six groups of 60 premolars in need of endodontic treatment. Groups were defined based on the...

Background: Biological width is a natural defensive space for periodontal tissue which important maintaining healthy so that it can support the success of dental restoration treatment. The localized alveolar bone loss, gingival recession, hyperplasia or combination all three be caused by poor biological restoration. obtained through crown lengthening when teeth have caries subgingival fractures...

introduction: prefabricated metal and ceramic posts can be used with different kinds of core materials as an alternative to the conventional casting post and cores. it is unclear how these post and core systems can withstand different kind of forces in the mouth. the purpose of this study was to compare the fracture strength of endodontically treated, crowned maxillary incisors restored with ca...

Silica fibers are nowadays cornerstones in several technological implementations from long-distance communication, to sensing applications many scenarios. To further enlarge the functionalities, compactness, and performances of fiber-based devices, one needs reliably integrate small-footprint components such as sensors, light sources, detectors onto single optical fiber substrates. Here, a nove...
