Objective: to assess the amount of vertical and lateral gingival tissue displacement recovery obtained by aretraction cord Magic Foam® paste. Material Methods: twenty- two participants, requiring full coverageprosthesis in anterior area, were prepared using a deep subgingival chamfer finish line, then randomly allocatedto retraction group (Group RC, n = 11 teeth) or Paste FP, teeth).The was mea...

Objective: This study aimed to examine the effects of three distinct file systems with two motion types—rotary and reciprocation—on development dentinal microcracks after root canal preparation using a stereomicroscope. Methods: Sixty mandibular molars curvature 30° were decoronated divided into groups (Vortex Blue, Mtwo, ProTaper Next) subgroups (rotary reciprocating motions). The samples then...

A fluorescence stereomicroscope system was developed in order to observe in situ the distribution of nuclei in intravascular Bong-Han ducts and corpuscle tissues by injecting acridine orange, which stained specifically nuclei. Intravascular Bong-Han corpuscles, connected with Bong-Han ducts could be detected in the aortas of rats, mice, and rabbits.

In this study, a novel non-toxic, biodegradable bacteria-based healing agent known as alkanoate derivatives (AKD) derived from wastewater was investigated for its self-healing efficiency of the mortar specimens in comparison to already-developed agents made lactic acid (PLA). Mortar with different percentages inclusions (2.6% and 5% w/w cement) have been evaluated study. To assess improvements ...

Front cover: The four images (in clockwise order) illustrate biofilm development on paper machine surfaces. FESEM image of Deinococcus geothermalis cells attached to a stainless steel surface ⇒ FESEM image of interconnected cells of D. geothermalis within a cell cluster ⇒ Stereomicroscope image of biofilm microcolonies ⇒ Photograph of mature biofilms adhering to stainless steel surfaces in the ...

Ischnopelta Stål, 1868 is a Discocephalini genus with three known species, I. scutellata (Signoret, 1851), oblonga (Fieber, and luteicornis (Walker, 1867), distribution restricted to South America. The examination of 284 specimens from several localities in Venezuela, Brazil, Bolivia, Argentina, Paraguay, revealed the existence new species. Measurements 24 morphometric parameters were taken usi...

Fusion of teeth is the union of two or more tooth germs, which are usually separated. Depending upon the stage of odontogenesis, it can be complete or incomplete. The present case describes fusion between the maxillary primary right central and lateral incisor with a supernumerary tooth. Clinical and radiographic examination revealed the presence of fused triple teeth. The fused teeth were extr...

Arsenic chalcogenide microlenses (As2S3) produced by an original procedure have been used for focusing the red – infrared laser light direct through an optical fiber. The microlenses with diameter in the range 150 – 400 m were glued on the optical single-mode fiber ends by Canada balm under optical microscope. The focusing effect of the microlenses was investigated in a stereomicroscope, and th...

The embryonic changes during the development of the freshwater prawn, Macrobrachium americanum are described from observations made on live embryos based on the percentage-staging method. Eggs were observed with a stereomicroscope to obtain descriptions of embryonic periods. This prawn has an incubation time of 18 days at 24◦C. Ten periods are described and illustrated. A comparison of this dev...

Background/Aim: This study aimed to evaluate the precision of Raypex 6 apex locator in locating apical constriction (AC) and major foramen (MF) during a root canal treatment compared with microscopic evaluation. Another aim present was accuracy presence different irrigating solutions (NaOCl, saline, EDTA, etidronic acid-HEBP). Material Methods: One hundred nine patients were included this rando...
