BACKGROUND/AIM There is a controversial opinion among implantologists on the method of dental implantation that provides more favourable response of soft and bone tissues. The aim of this study was to pathohistologicaly compare the influences of one- and two-phase implant surgical methods on the periimplant epithelial tissues. METHODS The experiment was performed on 10 dogs. Eight weeks follo...

One of the primary flaws with current digital signature technology is that a digital signature does not “feel” or resemble a traditional seal or personal signature to the human observer; lacking a sense of visualisation and changing each time it is applied. This paper reviews the historical value of seals in Eastern and Western cultures to provide a basis to enhance global acceptability of exis...

OBJECTIVE The aim of this study was to the determine impact of severe esophageal anastomotic leak (SEAL) upon long-term survival and locoregional cancer recurrence. BACKGROUND The impact of SEAL upon long-term survival after esophageal resection remains inconclusive with a number of studies demonstrating conflicting results. METHODS A multicenter database for the surgical treatment of esoph...

OBJECTIVES To evaluate in vitro the effect of cavity preparation with microburs and diamond-coated ultrasonic tips on the microleakage and marginal fit of six end-root filling materials. STUDY DESIGN. The following materials were assessed: amalgam (Amalcap), zinc oxide eugenol (IRM), glass ionomer (Vitrebond), compomer (Cavalite), mineral particle aggregate (MTA) and composite (Clearfil). Cavit...

An ultrasonic testing method employing the pulse-echo inspection technique was developed to assess the integrity of annular seals surrounding casings (i.e.. instrument tubes or well casings). This nondestructive testing method permits testing aseal from inside acasing without disturbing the casing, seal. or formation. Seals constructed with cement-based and bentonite-based sealants surrounding ...

The carrying capacity of the French Frigate Shoals (FFS) region for the endangered Hawaiian monk seal was appraised using an updated version of the original FFS Ecopath model (Polovina 1984). Model parameters were updated using recent literature, and data from surveys of the seal population and its bottom-associated prey. Together they produced a static mass balance model for 1998 when the prey...

Security and reliability are the main focus of annular metal seal assembly. It is concluded that the factors influence sealing performance of annular metal seal assembly most in view of working conditions of annular metal seal assembly. Taking major influencing factors with response surface method (RSM) analysis, and determining coefficient of regression analysis with finite element method (ANS...

Root canal treatment quality has a direct bearing on healing in the periradicular area. There are various methods to assess the quality of root canal treatment. Radiographic assessment in conjunction with clinical assessment remains one of the most commonly employed methods to predict the prognosis of endodontically treated teeth. The objective of this study was to assess the quality of root ca...

Abstract Titanium (Ti) and its alloys are widely used as dental implant materials because of their high mechanical properties, biocompatibility, corrosion resistance. This research was undertaken to study the effect polymethyl-methacrylate (PMMA) sealing layer on performance plasma electrolytic oxidation (PEO)-coated titanium-based implants in pure saliva fluoride-containing solutions. The phas...
