Chemometrics-Assisted Raman Spectroscopy Characterization of Tunable Polymer-Peptide Hybrids for Dental Tissue Repair.

The interfaces that biological tissues form with biomaterials are invariably defective and frequently the location where failure initiates. Characterizing the phenomena that lead to failure is confounded by several factors including heterogeneous material/tissue interfaces. To seamlessly analyze across these diverse structures presents a wealth of analytical challenges.

Using learning management software data to compare students' actual and self-reported viewing of video lectures.

Purpose: Student engagement is typically measured by class attendance and questionnaires. Learning management systems (LMS) provide additional sources of objective data that can evaluate student performance. This study compared dental students' self-report of course video viewing with LMS data.

Dental Students' Study Habits in Flipped/Blended Classrooms and Their Association with Active Learning Practices.

In recognition of the importance for dental education programs to take a student-centered approach in which students are encouraged to take responsibility for their learning, a pediatric dentistry course redesign aimed at promoting greater active and self-directed learning was implemented at one U.S. dental school.

Flipping the Classroom: Assessment of Strategies to Promote Student-Centered, Self-Directed Learning in a Dental School Course in Pediatric Dentistry.

The aim of this study was to explore student and course director experiences with the redesign of a traditional lecture-based course into a flipped classroom for teaching didactic content in pediatric dentistry to second-year dental students. The study assessed student satisfaction, extent of student engagement, overall course grades, and course director satisfaction. The students enrolled in a flipped classroom pediatric dentistry course (spring semester 2014; SP14) were asked to complete pre- and post-course questionnaires to assess their perceptions of active learning, knowledge acquisition, and course satisfaction.

Posterior composite restoration update: focus on factors influencing form and function.

Restoring posterior teeth with resin-based composite materials continues to gain popularity among clinicians, and the demand for such aesthetic restorations is increasing. Indeed, the most common aesthetic alternative to dental amalgam is resin composite. Moderate to large posterior composite restorations, however, have higher failure rates, more recurrent caries, and increased frequency of replacement.

Durable bonds at the adhesive/dentin interface: an impossible mission or simply a moving target?

Composite restorations have higher failure rates, more recurrent caries and increased frequency of replacement as compared to dental amalgam. Penetration of bacterial enzymes, oral fluids, and bacteria into the crevices between the tooth and composite undermines the restoration and leads to recurrent decay and failure. The gingival margin of composite restora tions is particularly vulnerable to decay and at this margin, the adhesive and its seal to dentin provides the primary barrier between the prepared tooth and the environment.

Adhesive/Dentin interface: the weak link in the composite restoration.

Results from clinical studies suggest that more than half of the 166 million dental restorations that were placed in the United States in 2005 were replacements for failed restorations. This emphasis on replacement therapy is expected to grow as dentists use composite as opposed to dental amalgam to restore moderate to large posterior lesions. Composite restorations have higher failure rates, more recurrent caries, and increased frequency of replacement as compared to amalgam.
