Chelation in root canal therapy reconsidered.
TLDR
Assessment of interactions of EDTA and citric acid (CA) with sodium hypochlorite (NaOCl), the indispensable endodontic irrigant, indicated that NaOCl had no negative effect on calcium-complexing ability of chelators, and STP was too weak a complexing agent to warrant further studies.
Effects of ethylenediaminetetraacetic, etidronic and peracetic acid irrigation on human root dentine and the smear layer.
TLDR
The statistical comparison of the protocols regarding calcium elution revealed that protocol (1) yielded less calcium than (3), which yielded less than protocols (2) and (4).
Polyetheretherketone-a suitable material for fixed dental prostheses?
TLDR
Acid etching should be applied when PEEK is used as substructure material and composite veneering material is applied and in this combination, PEEK might be a suitable material for FDPs, especially in load-bearing areas.
Interactions of ethylenediamine tetraacetic acid with sodium hypochlorite in aqueous solutions.
TLDR
Ethylenediamine tetraacetic acid retained its calcium-complexing ability when mixed with NaOCl, but EDTA caused NaO Cl to lose its tissue-dissolving capacity and virtually no free chlorine was detected in the combinations.
Tissue-dissolving capacity and antibacterial effect of buffered and unbuffered hypochlorite solutions.
TLDR
Results of this study do not demonstrate any benefit from buffering sodium hypochlorite with sodium bicarbonate according to Dakin's method, and an irrigation solution with less dissolving potential may be obtained by simply diluting stock solutions of NaOCl with water.
Chemical and antimicrobial properties of calcium hydroxide mixed with irrigating solutions.
TLDR
Ca(OH)2 is a strong alkali, whose pH is not changed when adding weak acids or alkalis in aqueous suspensions, whose antimicrobial properties are similar to equivalent mixtures with saline.
Impact of toothpaste slurry abrasivity and toothbrush filament stiffness on abrasion of eroded enamel – an in vitro study
TLDR
Toothbrush abrasion of eroded enamel is influenced mainly by the abrasivity of the toothpaste slurry, but is also modified by toothbrush filament stiffness.
Discoloration of manually fabricated resins and industrially fabricated CAD/CAM blocks versus glass-ceramic: effect of storage media, duration, and subsequent polishing.
TLDR
The discoloration was extrinsic and decreased after polishing for the majority of the tested materials, and all CAD/CAM resins showed similar color stability compared to the control group.
Comparison of the Effects of TiF4 and NaF Solutions at pH 1.2 and 3.5 on Enamel Erosion in vitro
TLDR
TiF4 at pH 1.2 was more effective in protecting against enamel erosion than NaF, and the Ti and F surface composition was analysed by one-way ANOVA separately for each element.
