Visual Versus Digital Color Determination of 3D-Printed Teeth as an Exercise in Dental Students' Education.

Visual color determination is part of the daily routine in dental practice. However, it is not a part of dental education so far. The aim of this study was to evaluate whether visual or digital tooth color determination of 3D-printed teeth is a reliable tool for inexperienced dentistry students.

Visual Tooth Color Determination with Different Reference Scales as an Exercise in Dental Students' Education.

Visual color determination (VCD) requires color competence and individual training. The aim of this study was to evaluate the deviations in students' VCD with two different reference scales. The research hypothesis was that none of the color references would provide a better result.

Influence of tongue position on the determination of tooth shade.

Statement Of Problem: Dentists frequently use electronic devices to determine tooth color. However, neither the instructions for these devices nor the accompanying brochures refer to the environmental conditions required at the point of measurement.

Purpose: The purpose of this multicenter prospective clinical study was to reveal whether a change in the oral background influences tooth color determination.

Does gender and experience influence shade matching quality?

Objectives: To evaluate the influence of gender and level of experience on shade matching quality.

Methods: A study was simultaneously performed at 15 universities located in 9 countries. A total of 614 color normal participants completed all phases of the experiment.

Retentive characteristics of Ankylos SynCone conical crown system over long-term use in vitro.

18 Ankylos SynCone conical crowns with 4-degree angle and 18 SynCone conical crowns with 6-degree angle were tested in vitro for a total of 5,000 insertion-separation cycles to investigate their retentive characteristics. Under 20 N insertion force, the retentive force of Ankylos SynCone conical crown system was between 5 and 10 N. The rententive force kept almost constant during the entire testing cycles.
