Mineralized collagen plywood contributes to bone autograft performance.

Autologous bone (AB) is the gold standard for bone-replacement surgeries, despite its limited availability and the need for an extra surgical site. Traditionally, competitive biomaterials for bone repair have focused on mimicking the mineral aspect of bone, as evidenced by the widespread clinical use of bioactive ceramics. However, AB also exhibits hierarchical organic structures that might substantially affect bone regeneration.

Non-surgical Treatment of Severe Drug-Influenced Gingival Enlargement: A Report of Two Cases.

Drug-influenced gingival enlargement (DIGE) is a well-known adverse drug reaction associated with multiple medications. Although a benign condition, DIGE can have a significant impact on patients' aesthetic comfort and function. A surgical resection approach is usually proposed to treat severe and generalized DIGE.

Perceptions regarding the use of a three-dimensionally-printed manufactured educational simulator for periodontal treatment of intraosseous and interradicular lesions.

Purpose/objectives: Treating intraosseous lesions (IOLs) and interradicular bone lesions (IRLs) is an extremely technical dental procedure in periodontics. Instrumentation of these lesions is often perceived as difficult by students and inexperienced dentists before they perform a certain number of procedures on patients in the clinic. The aim of this article is to evaluate a cost-effective three-dimensional (3D)-printed educational simulator for the periodontal treatment of IOLs/IRLs (including scaling, incisions and sutures).

Oxide nanolitisation-induced melt iron extraction causes viscosity jumps and enhanced explosivity in silicic magma.

Explosivity in erupting volcanoes is controlled by the degassing dynamics and the viscosity of the ascending magma in the conduit. Magma crystallisation enhances both heterogeneous bubble nucleation and increases in magma bulk viscosity. Nanolite crystallisation has been suggested to enhance such processes too, but in a noticeably higher extent.

Atmosphere injection of sea salts during large explosive submarine volcanic eruptions.

The 15 January 2022 submarine eruption at Hunga volcano was the most explosive volcanic eruption in 140 years. It involved exceptional magma and seawater interaction throughout the entire submarine caldera collapse. The submarine volcanic jet breached the sea surface and formed a subaerial eruptive plume that transported volcanic ash, gas, sea salts and seawater up to ~ 57 km, reaching into the mesosphere.
