Fluid migration and distribution are important aspects of the evolution of sedimentary basins. An essential parameter affecting fluid flow is permeability. Even mm thick fractures have permeabilit ies many orders of magnitude above surrounding sediments, and thus have the potential of focusing fluid flow. It is a major task to establish the importance of these fractures as fluid conduits. One a...

Beach rock has only rarely been observed in the coasts. It is a hard costal sedimentary formations consisting of various beach sediments, lithified through the precipitation of carbonate cements. One such formation is noted on the South East Coast of Tamilnadu, India. The objective of this contribution is to collect and review information on reported occurrences, characteristics and formation m...

Ideal coronal reconstruction of endodontically treated tooth is still a challenge for restorative dentistry. Despite having varied types of commercially available posts, none of them meet all the ideal biological and mechanical properties. In this context a "Biological Post" serves as a homologous recipe for intraradicular rehabilitation of a fractured endodontically treated tooth by virtue of ...

Abstract The aesthetic result in the ceramic restoration of anterior teeth has always been a challenge clinical practice and, these cases, success depends on skills both clinician and dental technician. In current dentistry, main objective is to pursue results while preserving biological structures. Among various conservative techniques available for restorations, veneers are most advantageous,...

Thin ridges often pose hindrance in oral implant placement. Inadequate width of ridge requires Innovative techniques in placing implants. One of such techniques is ridge splitting technique, Which helps expansion of the ridge with or without fracture of cortical plates. This technique has the advantage of immediate implant loading, in comparison with other ridge widening techniques. This articl...

Abstract Soft or loose sandy soils, particularly in ground slopes and high rainfall zones, are potentially dangerous have caused many problems such as damage, landfall, even erosion. Bio-cementation through bacterial mineralization can be considered a “green” “eco-friendly” solution toward sustainable development. Urelytical bacteria that decompose urea for calcium carbonate precipitation were ...

Little data exists regarding outcomes following TKA performed with surface-cementation for the fixation of modular tibial baseplates with press-fit keels. Thus, we retrospectively reviewed the clinical and radiographic outcomes of 439 consecutive primary TKAs performed with surface cemented tibial components. There were 290 female patients and 149 male patients with average age of 62 years (ran...

The purpose of this study was to investigate the shear bond strength of metal discs luted to dentine using Resin Coating Technique. In this study the adhesives used were dentine bonding agents, namely, Clearfil SE Bond and Syntac Sprint which were applied one week prior to cementation of Cobalt Chromium (Co-Cr) alloy discs to determine if there was any increase in the bond strengths when later ...

PURPOSE The aim of this study was to evaluate the effect of tooth surface pre-treatment steps on shear bond strength, which is essential for understanding the adhesive cementation process. MATERIALS AND METHODS Shear bond strengths of different cements with various tooth surface treatments (none, etching, priming, or etching and priming) on enamel and dentin of human teeth were measured using...
