Comparison of cell proliferation on modified dental ceramics

Abstract

The aim of this study was to investigate the in¯uence of substrate characteristics such as chemical composition and surface morphology of dental ceramics to support cell attachment and proliferation. Thus, body (B) and shoulder (S) porcelain differing on their surface morphology and composition were treated with oxides CaO or CaO and P 2 O 5 and four modi®ed ceramics BCa, BCaP, SCa, SCaP were constructed, respectively. The modi®ed ceramics differ from their controls concerning their surface morphology as evaluated by Scanning Electron Microscope (SEM), and their surface chemical composition (Na, KP and Ca) as evaluated by Energy Dispersing Spectroscopy (EDS). All modi®ed ceramics support better than the control ceramics the cell proliferation over 72 h incubation period. Furthermore, higher rates of cell proliferation was detected in shoulder modi®ed ceramics (SCa and SCaP) than in all other cases. KEYWORDS

Evaluation of Candida albicans formation on feldspathic porcelain subjected to four surface treatment methods

“…The effects of different surface treatments -namely, natural glaze, overglaze, ion exchange, and polishing -on strength have been widely mentioned in published literature [1][2][3][4][6][7][8]23,25) , but not so with their effects on Candida adhesion on porcelain surfaces 16,17) . Against this backdrop of information scarcity, this study was undertaken to investigate the effects of different surface treatments on the adhesion and formation of C. albicans.…”

“…In the evaluation of Candida formation on several non-porcelain dental materials, surface roughness and aging in saliva were considered to be pivotal factors to the long-term success of these dental materials 14,16,17,25) . However, similar research efforts pale in comparison for the porcelain surface 13,[15][16][17]22,23) .…”

“…The XTT assay monitors and measures the metabolic activity, and it has been proved to be a simple, rapid, and reliable colorimetric method for quantitative determination of C. albicans adhesion on the surfaces of diverse materials 12,[19][20][21][22][23] . Based on published literature, the porcelain surface presents the least potential for the adhesion and biofilm formation of C. albicans 2,6,16,17) . However, to the best of the authors' knowledge, no research has been conducted to endorse the preferred choice of surface treatment vis-à-vis Candida adhesion and formation.…”

“…On the adhesion mechanism of this microorganism on intraoral prosthetic materials, numerous research studies have been conducted to examine this concern and gain more insight [11][12][13][14][15][16][17][18] . Paling in comparison, on the other hand, are the investigative efforts on the effects arising from the surface variations of porcelain materials, and the related long-term alterations, on Candida adhesion.…”

Comparative Evaluation of Cellular Response to Three Types of Zolid Surface Full Contour: Glazing, Polishing, and CO2 Laser

“…On the one hand, studying the effect of glaze by the CO2 laser, based on the hardness tests shows a significant increase in the hardness and surface properties. Compared with the routine glaze methods, of course, the cellular response should be evaluated in the long term and after the aging process to examine the stability of the changed layer and the rate of abrasion and stability after a health habit such as tooth brushing (Kokoti et al, 2001). …”
