Purpose Quantitative ultrasound (QUS) and resonance frequency analyses (RFA) are promising methods to assess the stability of dental implants. The aim this in vivo preclinical study is compare results obtained with these two techniques bone-implant contact (BIC) ratio, which gold standard implant stability.

Abstract Background Excessive cadmium can damage cell structure, inhibit enzyme activity, and affect metabolic process, thus, leading to decline of rice yield quality. Root is an important organ crops, the detection in root essential for limitation grains. Results In this study, laser-induced breakdown spectroscopy (LIBS) was applied quantitative analysis. Pretreatment methods, including median...
