OBJECTIVE In this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers. MATERIALS AND METHODS Part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. The teeth were imbedded in autopolimerize acry...

The genus Dolomedes Latreille, 1804 present a very wide range of distribution on every continent except Antarctica (Platnick 2013) However, only one species has been reported from Madagascar, Dolomedes saccalavus Strand, 1907, which is unfortunately based on a juvenile specimen and was destroyed in wartime. We consider this a nomen dubium. In this work, one new species of Dolomedes Latreille, 1...

The lycosid spider genus Lysania Thorell, 1890 contains just three species found in Borneo, China and Malaysia (World Spider Catalog 2014), which build small, horizontal, sheet-like webs (Lehtinen & Hippa 1979; Li et al. 2013). Members of the genus are characterised by having a male pedipalp without an articulated median apophysis, a beak-like lateral apophysis and wider conductor and female ge...

GIC, microleakage, Miracle Mix, MTA, root-end filling. Abstract The main objective of a root end filling material is to provide an apical seal that prevents the movement of bacteria and the diffusion of bacterial products from the root canal system into periapical tissues. The aim of this study was to compare the microleakage of three root end filling materials Mineral trioxide aggregate (MTA),...

Proboscis structure and sensilla types are important morphological characters for the systematic analysis of Lepidoptera families. There is no study on proboscis Aporia crataegi (Linnaeus, 1758) (Lepidoptera: Pieridae) despite fact that it an pest. For this purpose, A. were investigated by using stereomicroscope scanning electron microscope in detail. The results show has three sensillum (sensi...

This study aimed to compare the effect of four irrigation solutions for post space cleaning on bond strength between glass fiber and root dentine. Forty bovine roots were root-filled randomly divided into groups (n=10), according solution: CG (Control Group): saline solution; SH (Sodium Hypochlorite Group); CLX (Chlorhexidine group) EDTA (ethylenediaminetetraacetic acid group). Specimens submit...

The genus Modisimus Simon 1893 (Pholcidae) is distributed across the Americas from Venezuela to the USA, including the Caribbean Antilles, with an endemic species in the Galapagos Islands and one cosmopolitan species (World Spider Catalog 2015). Until now, 81 species of Modisimus have been described, of which 17 species are found in Mexico (World Spider Catalog 2015). In this paper, a new Mexic...

OBJECTIVE To evaluate the push-out bond strength of Biodentine (BD) in comparison with two available calcium silicate based materials, bioaggregate (BA) and ProRoot MTA (WMTA). MATERIALS AND METHODS One hundred and twenty-three Root dentin slices of freshly extracted single Rooted human teeth were randomly divided into three groups (n = 41) according to the used test material: WMTA, BA, BD. A...

The present paper aims to study the occurrence of monogenean species infecting gills wild Hemichromis elongatus (Pisces). Fish specimens were caught with nets, fixed in 10% formalin and then dissected. Monogenean found removed under a stereomicroscope needle, mounted between slide cover slip drop hematoxylin eosin. Among five parasite found, only O. voltaensis C. euzeti infesting their host alo...
