Three-Dimensional printed model for preclinical training in oral radiology.

Introduction: 3D printing is experiencing significant growth in the teaching and learning process. This study aims to present a 3D printed skull model for preclinical intraoral radiographic practice.

Materials And Methods: Two 3D printed mannequins were created.

Smartphone use as an aid in evaluating conventional radiographs.

This study aimed to evaluate the accuracy of smartphones for digitizing, sharing, and viewing conventional radiographic images. Eighty conventional radiographs of 40 teeth with metallic mesio-occlusodistal restorations (40 radiographs showing perfectly adapted restorations and 40 showing restorations with a 0.4-mm proximal gap) were digitized using a smartphone and then evaluated using 2 viewing methods: a light box (LB) and a smartphone screen (SS).

The use of smartphones in radiographic diagnosis: accuracy on the detection of marginal gaps.

Objective: To compare the accuracy of computer monitor and smartphone screen for radiographic diagnosis of marginal gap.

Materials And Methods: Forty teeth with mesial-occlusal-distal inlays (each tooth with a perfect fit and a 0.4-mm marginal gap restoration) were imaged with a phosphor plate system.
