Exploration Of Materials Used In 3-Dimensional Printing For The Dental Industry, Holly Chang Hayden
Scripps Senior Theses
A limiting factor in the digitization of dental devices is the availability of materials suitable for use in both dentistry and the new digital technologies. As a rapidly growing industry, three-dimensional printing (3DP) has the potential to disrupt traditional manufacturing and prototyping methods. A review of both restorative materials and the current 3DP materials has lead to a focus on fiber- reinforced composites in the exploration for a new 3DP material. In addition, another area worth exploring and investing in would be 3D bioprinting as it opens up the possibility of regenerative dentistry.

The Prevalence, Predictive Factors, And Classification Of Intrapulpal Cracks In Maxillary Premolars Requiring Endodontic Treatment, Sarah Krygowski
The Prevalence, Predictive Factors, And Classification Of Intrapulpal Cracks In Maxillary Premolars Requiring Endodontic Treatment, Sarah Krygowski
Theses and Dissertations
Cracked teeth may be difficult to diagnose. Craze lines rarely become symptomatic or require treatment. Cracks in the enamel and dentin alone may or may not become symptomatic and require restorative treatment. However, cracks extending into the enamel, dentin, and pulp chamber provide an avenue for bacteria to establish infection and this commonly results in symptoms and the need for endodontic and restorative treatment. The published endodontic literature has limited information regarding the prevalence or predictive factors for cracks extending into the pulp chamber of teeth. The purpose of this study was to determine the prevalence and classification of intrapulpal …
