STATEMENT OF PROBLEM Streptococcus mutans can adhere at restored tooth margins to cause recurrent caries. Limited information about surface quality and bacterial adherence is available for lithium disilicate ceramic materials. PURPOSE The purpose of this in vitro study was to investigate how bacterial adherence is influenced by commercially available preparations of lithium disilicate ceramic...

statement of problem: the effect of mouth washes on discolouration of dental ceramics with different surface preparations is not well documented. objectives: this in-vitro study has been conducted to evaluate the effect of chlorhexidine (chx) mouth rinse on colour stability of overglazed (op), autoglazed, (ap) or polished porcelain (pop) specimens. materials and methods: the restorative materia...

In this paper, we addressed the chemical composition and main features of a glazed Almohad ceramic assemblage recovered from Puig de Sa Morisca, rural Islamic site located in southwest Mallorca. The glazes were analyzed by means scanning electron microscope equipped with energy-dispersive spectrometer (SEM-EDS). archaeometrical analysis conducted allowed us to characterize technological choices...

The objective of this in vitro study was to evaluate the effects finishing protocols and oral hygiene procedures on surface mechanical properties CAD/CAM ceramics. Specimens (n = 96, (15x10x2mm) leucite glass-ceramic (LGC) feldspathic ceramic (FP) received polishing or glazing. Surface roughness (Ra) microhardness (VHN) were obtained with a profilometer hardness tester, respectively, before aft...

Samples of northern porcelain wares dating to between the 6th and 13th centuries from three most important Chinese ceramic kiln sites, Gongyi, Xing Ding have been studied in this work. The Sr isotope chemical compositions glazes these determined. Based on scientific results we able suggest raw materials used make glazes. Using Strontium isotopic analysis successfully shown that earliest use lim...
