Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei)

Journal of Anatomy, EarlyView.
This article demonstrates that the teeth and rostral denticles of an extinct clade of sawfish‐like skates display an extremely derived enameloid microstructure, similar to what is known among sharks. The presence of tooth‐like enameloid microstructure in dermal denticles opens new perspectives about the origins and development of chondrichthyan ...

A Technique for Characterizing Casting Behavior of Dental Alloys

Journal of Dental Research, 1985
A technique for characterizing casting behavior of dental alloys has been developed and tested. The method employs easily reproducible specimen patterns and uses equipment and procedures generally available in dental prosthetic laboratories. A castability value is arrived at by counting complete segments of a cast alloy grid.

The Fit of Certain Dental Casting Alloys Using Different Investing Materials and Techniques

Journal of Prosthetic Dentistry, 1966
Abstract The relative fit of castings for normal tooth preparations and the Bureau of Standards MOD die were investigated. As used, the phosphate investments gave a degree of fit comparable with the thermal expansion gypsum types followed in order by ethyl silicate and hygroscopic materials.

Evaluation of split‐cast techniques for remounting casts on a dental articulator: A survey and an in vitro study

European Journal of Dental Education, 2022
AbstractIntroductionThis study aimed to investigate the difference between senior dental students and prosthodontic faculty members regarding their opinions, attitudes and adoption of six split‐cast techniques for remounting complete dentures. The accuracy of each technique for measurements of the vertical and the anteroposterior dimensions was ...
