BACKGROUND The efficacy of endodontic irrigation procedures can be compromised by the complexity of the root canal system. Delivering irrigants to the apical third of curved canals presents a particular challenge to endodontists. This study compared the effects of two ultrasonic irrigation techniques on the penetration of sodium hypochlorite into the main canal and simulated lateral canals of c...

The use of reclaimed water for agricultural irrigation is an increasingly common practice, which recently has found its own European regulatory frame. However, the partial removal organic contaminants together with other xenobiotic substances in current wastewater treatment plants leads to occurrence residues such pollutants treated effluents. Wastewater reclamation techniques are thus required...

Coffee is the most appreciated beverage in worldwide; Brazil largest producer and exporter of this commodity. Organochlorine endosulfan was banned from country 2013 due to its teratogenic agent-related features. Since then, coffee plantations have experienced increased Hypothenemus hampei infestation rates. The aim current study assess variations rates Coffea arabica fruits brocaded by H. after...

The analysis of the existing mathematical models options for operation sprinkling machines on pneumatic wheel supports shows unconditional promising their use to create optimal conditions photosynthetic and symbiotic soybean apparatus, as well increase yields. expediency design surveys has been proven when improving wheels ensure equality transporting capabilities minimize slipping driving is p...

We introduce a new procedure for generating the binomial random graph/hypergraph models, referred to as online sprinkling. As an illustrative application of this method, we show that for any fixed integer k ≥ 3, the binomial k-uniform random hypergraph H n,p contains N := (1 − o(1)) ( n−1 k−1 ) p edge-disjoint perfect matchings, provided p ≥ log C n nk−1 , where C := C(k) is an integer dependin...

Irrigation underpins agricultural productivity. The purpose of irrigation is to match water supply to crop water demand. The effectiveness of irrigation depends on the quality of the timing and duration of watering events, also called irrigation scheduling. Most farmers use heuristic rules to determine irrigation events. This often leads to over-watering which results in lower crop yields and w...

OBJECTIVE To compare the ability to eliminate debris and open dentinal tubules of different ultrasound irrigation procedures. STUDY DESIGN Forty extracted single-rooted human teeth were instrumented with mechanical rotatory instrumentation, and divided into four groups: (n=10) according to the final irrigation technique: group A (control), 2.5% NaOCl irrigation with the Miraject needle and no...

INTRODUCTION The purpose of this study was to compare the debridement efficacy of EndoVac irrigation versus conventional needle irrigation in vivo. METHODS Seven adult patients with a total of 22 matched pairs of single-canaled vital teeth with fully formed apices were recruited. Canals were instrumented to a master apical file size #40/.04 taper. One tooth from each matched pair was irrigate...
