This clinical trial focused on collating the instrumentation time and quality of root canal obturation in primary molars treated with three techniques: adaptive, rotary, manual. A triple-armed, randomized controlled was performed 75 requiring pulpectomy treatment, divided into groups (n = 25 per group). The teeth Group 1 were instrumented an adaptive technique (XP-endo Shaper, FKG Dentaire, La ...

conclusions regarding the study limitations, dentinal cracks were observed in all files and distances from the apex. although there was more crack incidence in protaper files, no significant differences were noted regarding the studied systems and sections from the apex. materials and methods in an experimental in vitro trial, 80 maxillary and mandibular first molars were selected and their cro...

Using the Clark predictable representation formula, we give a proof of the FKG inequality on the Wiener space. Solutions of stochastic differential equations are treated as applications and we recover by a simple argument the covariance inequalities obtained for diffusions processes by several authors.

We investigate the maximal non-critical cluster in a big box in various percolation-type models. We investigate its typical size, and the fluctuations around this typical size. The limit law of these fluctuations are related to maxima of independent random variable with law described by a single cluster. Key-words: Maximal clusters, exponential law, Gumbel distribution, FKG inequality, second m...
