It is an established assumption that eroded dental hard tissues are particularly prone to toothbrush abrasion. Only a few studies have aimed to show this for dentine and, if so, disregarded the complex histological structure of this tissue. Therefore, the present study sought (i) to investigate the effects of toothbrushing on eroded dentine and (ii) to analyze how the organic matrix influences ...

PURPOSE This study was aimed to evaluate effect of the desensitizing pretreatments on the micro-tensile bond strengths (µTBS) to eroded dentin and sound dentin. MATERIALS AND METHODS Forty-two extracted molars were prepared to form a flat dentin surface, and then they were divided into two groups. Group I was stored in distilled water while group II was subjected to a pH cycling. Each group w...

Soil carbon (C) losses and soil translocation from tillage operations have been identified as causes of soil degradation and soil erosion. The objective of this work was to quantify the variability in tillage-induced carbon dioxide (CO2) loss by moldboard (MP) and chisel (CP) plowing across an eroded landscape and relate the C loss to soil properties. The study site was a 4 ha wheat (Triticum a...

Slaking is a rapid wetting of soil aggregates that affects their stability in the face effects water. The aggregate’s has an indirect influence on functioning through its minimising erosion. Testing slaking very simple, does not need additional complicated equipment and could be done for any point. was performed natural air-dry (7–10 mm) sampled from arable layers four different types soils wit...

Heavy metals and other trace elements that are not subject to degradation among the priority pollutants. Significant amounts of heavy related with variable valence deposited on soil surface as part aerosols. Accumulating in soil, they very slowly removed from it, only changing level content or state during migration, turning over time into a source secondary pollution. In this regard, an extrem...

Experimental studies provide a basis for understanding the mechanisms of rill erosion and can provide estimates for parameter values in physical models simulating the erosion process. In this study, we investigated sediment delivery during rill erosion in purple soil. We used the volume-replacement method to measure the volume of eroded soil and hence estimate the mass of eroded soil. A 12 m ar...
