The effective and safe method for preventing and treating bacteria-induced dental diseases by herbal plants and a recombinant peptide
Background This study was conducted aimed at evaluating the antibacterial property of the recombinant peptide of bacteriocin entrocin P (EnP), the essential oil of Cuminum cyminum, and the extract of Ferulago angulata on some oral pathogens. Besides, the cytotoxicity of EnP was evaluated. Material and methods The antimicrobial property was tested on streptococcus mutans (ATCC 35668), streptococcus salivarius (ATCC 9222), streptococcus oralis (ATCC 35037), and Enterococcus faecalis (ATCC 29212), using the microbroth dilution method. The 0.2% Chlorhexidin (CHX) mouthwash was used as the control group. Besides, the cytotoxicity analysis was done on gingival fibroblasts by the MTT colorimetric …
The Micro-Shear bond strength of different cements to commercially pure titanium
Background The most appropriate luting agent for attaching the prefabricated Ti-based insert of hybrid abutments to its ceramic component has not yet been determined. This study was done aimed at examining the micro-shear bond strength (μSBS) of different cements to commercially pure titanium (Cp Ti). Material and Methods A total of 100 milled cubes of Cp Ti was airborne-particle abraded using 250 μm aluminum oxide particles. Specimens were then divided into 5 groups (n=20) according to the type of resin cement used: (1) Panavia F.2, (2) Rely X U200, (3) Panavia SA LUTING Plus, (4) GC Fuji I, and (5) GC FujiCEM 2. After 24h storage, half of the samples were subjected to 5000 cycles of therm…
