Impact Absorption Power of Polyolefin Fused Filament Fabrication 3D-Printed Sports Mouthguards: In Vitro Study.

Background/aim: This study aims to evaluate and compare the impact absorption capacities of thermoformed ethylene vinyl acetate (EVA) mouthguards and 3D-printed polyolefin mouthguards used in sports dentistry applications. The objective is to determine whether 3D-printed polyolefin mouthguards offer superior impact toughness compared to traditional EVA mouthguards commonly used in sports settings.

Materials And Methods: Six material samples were assessed: five pressure-formed EVA mouthguards (PolyShok, Buffalo Dental, Erkoflex, Proform, and Drufosoft) and one 3D-printed synthetic polymer (polyolefin).

Assessment of learning outcomes of first year dental students using an interactive Nearpod educational platform.

Purpose: The impact of COVID-19 required revisions in curricula, especially among professional programs that have traditionally required hands-on learning of content. This study endeavored to assess the level of effectiveness of the online presentation of material both qualitatively and quantitatively in a 5-week module on cariology for first-year dental students. Quantitative analysis of the assessment data was required to determine if an interactive engagement platform increased student outcomes.
