The contribution of tephra constituents during biogenic silica determination: implications for soil and palaeoecological studies

Biogenic silica (BSi) is used as a proxy by soil scientists to identify biological effects on the Si cycle and by palaeoecologists to study environmental changes.Alkaline extractions are typically used to measure BSi in both terrestrial and aquatic environments.The dissolution properties of volcanic glass in tephra deposits and their nanocrystallin

CO2 and Diode Lasers vs. Conventional Surgery in the Disinclusion of Palatally Impacted Canines: A Randomized Controlled Trial

Background: The aim of this RCT is to show the effectiveness of laser technology for the exposure of palatally impacted canines, using a CO2 or diode laser, and to evaluate the possible bio-stimulation effect of the laser on the spontaneous eruption of the canine.Methods: This study was carried out on a sample of 27 patients, divided randomly into
