BACKGROUND AND AIMS Root diameter, especially apical diameter, plays an important role in root development and function. The variation in diameter between roots, and along roots, affects root structure and thus the root system's overall foraging performance. However, the effect of diameter variation on root elongation, branching and topological connections has not been examined systematically i...

Root diameter, a critical indicator of root physiological function, varies greatly among tree species, but the underlying mechanism of this high variability is unclear. Here, we sampled 50 tree species across tropical and temperate zones in China, and measured root morphological and anatomical traits along the first five branch orders in each species. Our objectives were (i) to reveal the relat...

statement of problem: root surface contamination or infection can potentially change the consequences of regenerative periodontal therapies and therefore the modification and disinfection of the contaminated root surfaces are necessary. objectives: this study aimed to compare the surface characteristics of the extracted human teeth after exposure to four root conditioners in different time peri...

introduction: the antimicrobial efficacy of root canal irrigant plays an important role in increasing the success of root canal treatment (rct). the aim of the present experimental study was to compare the antimicrobial activity of triphala (a plant-derived solution) with 0.5, 1, 2.5 and 5% concentrations of sodium hypochlorite (naocl), against enterococcus faecalis ( e. faecalis ). methods and...

Fine root respiration is a significant component of carbon cycling in forest ecosystems. Although fine roots differ functionally from coarse roots, these root types have been distinguished based on arbitrary diameter cut-offs (e.g., 2 or 5 mm). Fine root morphology is directly related to physiological function, but few attempts have been made to understand the relationships between morphology a...

in order to study the mode of genetic control and heritability of morphological characteristics important for the improvement of root weight, sugar yield and white sugar yield in tropical beet, griffing's diallel cross method along with the biplot display of diallel data were applied. nine sugar beet lines including 7112-36, 7173, 474, 452, 261, 436-104, sb-firoz, rr607 and 436 were crosse...

AIM To compare the apical fit in two dimensions of the first K-file versus the first Lightspeed LSX instrument binding at working length after an initial crown-down preparation. METHODOLOGY Twenty maxillary molars with fully developed roots and four separate root canals were selected. Canals were pre-flared with ProFile.04 taper instruments to three quarters of estimated working length. Worki...
