The aim of this study was to evaluate the ability of three obturation methods to seal root canals prepared using 0.06 taper rotary instruments. Forty-five extracted human single-rooted teeth were instrumented with 0.06 taper Profile nickel-titanium rotary files and randomly divided into three experimental groups containing 15 teeth each. The first group was obturated using the System B techniqu...

The purpose of this study was to evaluate the root-end sealing ability through dye leakage evaluation and the marginal adaptation through scanning electron microscopy (SEM) of some root-end filling materials. Thirty human uniradicular teeth were used. Teeth were divided into three groups: (1) retrofilled with MTA-Angelus, (2) with SuperEBA, and (3) with Vitremer. The root surfaces were isolated...

The hair samples of Ferdinand II of Aragon (1467-1496), King of Naples, whose mummy is preserved in the Basilica of San Domenico Maggiore in Naples, showed a high content of mercury, with a value of 827ppm. Furthermore, examination using a stereomicroscope and a scanning electron microscope (SEM) of head and pubic hairs of Ferdinand II, revealed a lice infestation. The reasons for the massive p...

The genus Allopachria Zimmermann, 1924 (Hydroporinae: Hyphydrini) with a rich diversity of species occurs throughout southeastern Asia. Recently eight new species were reported from China, Laos and Indonesia by Wewalka (2010) and another four new species from China were added by Bian & Ji (2010, 2012). In the most recent version of the World Catalogue of Dytiscidae, Nilsson (2013) listed 45 spe...

This study evaluated the repair bond strength of a nanohybrid resin composite to a novel CAD/CAM hybrid ceramic based on four intraoral ceramic repair systems. Vita Enamic (VE) CAD/CAM hybrid ceramic was used in this study. Specimens were divided into five test groups according to the repair method performed on the ceramic surface: Gr C (No treatment; control); Gr CZ (Cimara Zircon); Gr PR (Por...

The groundnut leafminer (Aproaerema modicella), has been reported from east African countries since 1998 and from South Africa since 2000. The study aimed at determining the biology and management of groundnut leafminer (GLM) in South Africa. In a survey, 10 parasitic Hymenoptera species were identified. Two hyperparasitoids were also recorded for the first time in South Africa. GLM flight acti...

The occurrence of feline myiasis is rare. Massive infestations of dipteran larvae can lead to death if not treated at an early stage. Auricular, anal and umbilical myiasis was detected in three neonatal kittens. The dipteran larvae were collected, fixed in 70% alcohol and clarified with 10% KOH for a few days. Later, larvae were dissected under the stereomicroscope, mounted on slides and then i...

AIM The aim of this in vitro study was to evaluate if there is any significant difference in apical leakage when gutta-percha is removed immediately after obturation for postspace preparation or after a week. MATERIALS AND METHODS Two commonly used sealers AH26 and tubliseal were used in four groups each consisting of 20 teeth each. The tooth was sectioned at the amelocemental junction to lea...

The information in the literature on effect of printing layer thickness interim 3D-printed crowns is limited. In present study, trueness and margin quality composite resin was investigated compared with milled crowns. were printed 3 different thicknesses (20, 50, 100 ?m) by using a hybrid based acrylic esters inorganic microfillers or from polymethylmethacrylate (PMMA) discs digitized an intrao...

The wild dioecious plant Corema album, endemic to the Atlantic coast of Iberian Peninsula, has potential become a new crop and integrate berry fruit market. Due its potential, aim this study was propose BBCH (Biologische Bundesanstalt, Bundessortenamt CHemical Industry) scale for species. Based on field observation, principal growth stages were described sequentially established. Photographs st...
