Evaluation of microleakage of RSA Roekoseal Automix root canal sealer
The sealing ability of RSA Roekoseal Automix root canal sealer using ThermaFil Plus and cold lateral condensation was compared to Roth's 801 root canal sealer. Fifty-two single canaled roots of extracted teeth were divided into four groups of twelve and instrumented to size 6 with .06 taper series …

Microleakage in new resin-modified glass ionomer cements using new no-rinse conditioners : an in-vitro study
… release and uptake, excellent seal against microleakage, and biocompatibility. The main objective of this study was to compare the microleakage of two new paste-paste glass ionomer systems to their traditional RMGIC counterparts when conditioning the dentin with newly developed no-rinse …

Μελέτη in vitro της οριακής μικροδιείσδυσης υαλοιονομερών κονίων και σύνθετων ρητινών με τη χρήση συγκολλητικών παραγόντων σε κοιλότητες Vης ομάδος
… STUDY SHOWED THAT ALL MATERIALS RESISTER MORE TO MICROLEAKAGE IN THE OCCLUSAL. THE OSTEINE-DENTIN CERVICAL MARGIN IS THE WEAK LOCATION TO THE MICROLEAKAGE OF THE RESTORATION. THE DENTIN BONDING AGENTS USED IN COMBINATION WITH THE COMPOSITES TENT TO REDUCE THE MICROLEAKAGE BUT DO NOT TO ELIMINATE …

An In-Vitro Comparison of Microleakage With E. faecalis In Teeth With Root-End Fillings of Proroot MTA and Brasseler's EndoSequence Root Repair Putty
… this investigation was to compare the bacterial microleakage of these two root-end filling materials exists. Sixty-two human, single-rooted, mandibular premolars in which extraction was indicated were accessed and instrumented in an orthograde fashion with hand and rotary files. Root resection of …

Influência da irradiação com lasers de alta potência na microinfiltração bacteriana e fúngica em dentes humanos retrobturados com MTA
This in vitro experimental study evaluated lhe microleakage of E. faecalis and C. albicans in roots whose ressected apical surfaces and retrocavities had suffered irradiation from Nd:YAG, Diode 810 nm and Er,Cr:YSGG lasers, and later retrofiled with MTA. Seventy roots had been prepared, obturated, …

Debonding and adhesive remnant cleanup: an in vitro comparison of bond quality, adhesive remnant cleanup, and orthodontic acceptance of a flash-free product
… selected and scanned using microCT to analyze microleakage into the adhesive layer. Twenty orthodontists debonded twenty mounted dental arches. The adhesive remnant on the bovine incisors was quantified. The orthodontists then removed the remaining adhesive. The time required for complete …

An InVitro Leakage and Viscosity Analysis of Root End Filling Materials
… lower than the other two materials tested. Microleakage of root end fillings was assessed in a passive diffusion model. Leakage groups were compared with a one-way ANOVA (p < 0.05). No significant difference was found. Particle size and shape were evaluated with the SEM. MTA Angelus Fluid …

Development of methodologies for the assessment of oral prostheses.
… Appraisal of the system was then achieved using microleakage examination. The material used as a substitute for dentine was beechwood which has mechanical and granular properties similar to dentine. The mode of fatigue loading has been combined direct shear, torsion and bending. Finite clement …

Influence of process parameters and manufacturing defects on the properties of thermoplastic composite pipes.
… coefficients, which can lead to debonding and microleakage in composite structures. Despite the expected increase in thermal conductivity with viscosity reduction, there is contradictions that increase in fibre fraction raise the conductivity. Hence, this thesis presents findings of in-situ …
