Apical leakage after root canal filling with an experimental calcium hydroxide gutta-percha point
This study was an in vitro analysis of the apical seal of root canals filled with an experimental calcium hydroxide gutta-percha point. One hundred and ten recently extracted human permanent teeth with a single root were ...
A method for plotting the complementary root locus using the root-locus (positive gain) rules
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Mechanical and biological approaches to alleviate soil compaction in tropical soils: assessed by root growth and activity (Rb uptake) of soybean and maize grown in rotation with cover crops
Chiselling has been used to alleviate soil compaction but cover crops with deep, vigorous roots can improve root growth and activity of the cash crop for a longer time. The determination of root activity in addition to ...
Differences between root traits of early- and late-successional trees influence below-ground competition and seedling establishment.
(Journal of Tropical Ecology, v. 32, n. 4, p. 300-313, Jul. 2016., 2016)
Root canal treatment of three-rooted maxillary second premolars: Report of four cases
(Wiley-Blackwell Publishing, Inc, 2009-08-01)
The aim of this report is to contribute to a better understanding of the radiographic, clinical and anatomic findings in maxillary second premolars. This paper reports the endodontic treatment of two cases of three-rooted ...
A microscopic analysis of the effects of root surface scaling with different power parameters of er,cr: YSGG laser
The aim of this study was to evaluate the effects of different power parameters of an Erbium, Cromium: Yttrium, Scandium, Gallium, Garnet laser (Er,Cr:YSGG laser) on the morphology, attachment of blood components (ABC), ...
Repair characteristics of horizontal root fracture: a case report
(Blackwell Munksgaard, 2002-04-01)
Radicular fractures in permanent teeth are uncommon injuries among dental traumas, comprising 0.5-7% of the cases. Fracture occurs most often in the middle-third of the root and rarely at the apical-third. The present paper ...
Root-system of peanuts as affected by phosphorus fertilization
(Empresa Brasileira de Pesquisa Agropecuária (EMBRAPA), 1994-11-01)
There have been some responses of peanut roots to phosphorus. An experiment was carried out to study peanut root growth and distribution as related to P in the soil. The cultivars Tatu, Oira and Tup4 and the lines FCA 170 ...
A split-pot experiment with sorghum to test a root water uptake partitioning model
Correct modeling of root water uptake partitioning over depth is an important issue in hydrological and crop growth models. Recently a physically based model to describe root water uptake was developed at single root scale ...
