External apical root resorption in retracted incisors
(2012)
AIM: To evaluate the occurrence of external apical root resorption (EARR) in the incisors after anterior retraction in corrective orthodontic treatment with first premolar extractions and whether it was related with the ...
A split-pot experiment with sorghum to test a root water uptake partitioning model
(SPRINGER, 2010)
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 ...
Fine root isotropy in Eucalyptus grandis plantations. Towards the prediction of root length densities from root counts on trench walls
(Springer, 2010-09-01)
The objectives of the study were to assess changes in fine root anisotropy and specific root lengths throughout the development of Eucalyptus grandis ( W. Hill ex Maiden) plantations and to establish a predictive model of ...
Difference in hydroxamic acid content in roots and root exudates of wheat (Triticum aestivum L.) and rye (Secale cereale L.): Possible role in allelopathy
(Kluwer Academic Publishers-Plenum Publishers, 1991)
Hydroxamic acids (Hx) produced by some cereal crops have been associated with allelopathy. However, the release of Hx to the soil by the producing plant-an essential condition for a compound to be involved in allelopathy-has ...
Root morphology can be a risk factor for periodontal damage and root resorption in orthodontic movement
(2017-01-01)
Aim: The study evaluated, using histomorphometry, the percentage of hyaline area in periodontal ligament (PDL) and root resorption in orthodontic tooth movement (OTM). Methods: Ten rats were divided into two groups. G3 ...
Effect of intracanal dressings on repair and apical bridging of teeth with incomplete root formation
(Munksgaard Int Publ Ltd, 1993-02-01)
Periapical repair and apical bridging were studied in dog's teeth with incomplete root formation and induced chronic periapical lesions treated with different dressings. A total of 75 root canals from the upper and lower ...
Yield and nutritional requirements of cassava in response to potassium fertilizer in the second cycle
(2017-12-14)
Potassium (K) is one of the most absorbed nutrients by cassava because it acts on the synthesis and starch accumulation in the storage roots. Here, we show that K application at the beginning of the second vegetative cycle ...
Effectiveness of gutta-percha and Resilon in filling lateral root canals using the Obtura II System
(Sociedade Brasileira de Pesquisa Odontológica (SBPqO), 2011-05-01)
The aim of this study was to evaluate the effectiveness of gutta-percha and Resilon in filling lateral root canals by using the Obtura II system. Root canals of artificial teeth were prepared using a standard protocol, and ...
Effect of obturation technique using a new bioceramic sealer on the presence of voids in flattened root canals
(2021-01-01)
The aim of this study was to evaluate the filling ability of a new ready-to-use calcium silicate-based sealer using thermoplastic or single-cone technique in flattened root canals. Twenty-four flattened distal canals of ...
