Optical microscopy and morphometric analysis were used in this study to evaluate, in vitro, the cleaning of the apical region in root canals with mild or moderate curvatures subjected to biomechanical preparation with a rotary system, as well as to assess the amount of extruded material to the periapical area. Lateral incisors (n = 32), 16 with curvature angles smaller or equal to 10º (GI) and ...

We examined the influence of aluminum and calcium (and certain other cations) on hormone transport in corn roots. When aluminum was applied unilaterally to the caps of 15 mm apical root sections the roots curved strongly away from the aluminum. When aluminum was applied unilaterally to the cap and 3H-indole-3-acetic acid was applied to the basal cut surface twice as much radioactivity (assume...

An essential prerequisite to perform any dental procedure is a clear understanding and knowledge of anatomy its possible variations. The root canal system characterized for complex morphology, which varies among populations, individuals in the same population even person. aim this study was evaluate by CBCT number, curvature, length roots first second maxillary premolars Mexican population. In ...

Measuring the dynamics of plant growth is fundamental to the understanding of plant development processes. This paper describes a high-throughput, automatic method to trace Arabidopsis (Arabidopsis thaliana) seedling roots grown on agarose plates. From the trace, additional software can quantify length, curvature, and stimulus response parameters such as onset of gravitropism. The method combin...

GASTRIC DIVERTICULA ON THE GREATER CURVATURE (Abstract): Gastric diverticula are extremely rare in the surgical pathology and is usually asymptomatic. Their discovery is in most cases incidentally, on radiographic examination or autopsy. The most frequent localization is on the posterior wall of the cardia and on the lesser curvature of the stomach. Symptomatic gastric diverticula are rare, mai...

Article history: Received 1 December 2015 Received in revised form 19 January 2016 Accepted 20 January 2016 Available online 22 January 2016 The design and fabrication of large radii of curvature micro-lenses in single crystal chemical vapour deposition diamond is described.

The aim of this study was to evaluate the technical quality of root canal treatment carried out by house surgeons at a dental teaching hospital in Islamabad. Radiographic records of the 64 root canal treated teeth of patients were analyzed to find the adequacy of treatment they received. The final sample consisted of 60 teeth. Root treatment was considered adequate if the apical length of obtur...

to evaluate differences in the root and canal configurations of mandibular permanent anterior incisors and canines in an iranian population by means of cone beam ct (cbct) images.four hundred cbct images of mandibular permanent incisors and canines that met the inclusion criteria were evaluated. vertucci's classification was used to evaluate the number of roots, number of root canals, root leng...
