INTRODUCTION The aim of this study was to analyze and characterize root canal morphology of mandibular molars of the Brazilian population by using cone-beam computed tomography (CBCT). METHODS Patients who required CBCT radiographic examinations as part of their routine examination, diagnosis, and treatment planning were enrolled in the study. A total of 460 healthy, untreated, fully develope...
A case of unusual root morphology is presented to demonstrate anatomic variations in mandibular second molars. The most common configuration of mandibular second molar is to have two roots with three root canals; however mandibular molars may have many different combinations. Endodontic therapy was performed in a mandibular second molar with 3 separate roots 2 located mesially and one distally....
Hairy and adventitious roots are efficient systems for expressing recombinant proteins. In the present study, the amount of DrsB1-CBDAvr4 recombinant protein in hairy and adventitious root systems was compared. To this end, the effect of different factors on the optimization of culture conditions to obtain adventitious and hairy roots was evaluated in three separate experiments by assessment of...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
Treating Arabidopsis roots with exogenous auxin results in dramatic changes in cellular processes including de novo induction of lateral roots which later emerge through the overlying cells. Microarray experiments reveal approximately 80 genes that are substantially up-regulated in the root over the first 12 h following auxin treatment. We hypothesize that the observed increase in expression of...
The diversity of arbuscular mycorrhizal fungi (AMF) in 10 Oregon vineyards was assessed by examining spores in soil and amplifying mycorrhizal DNA from roots. Seventeen spore morphotypes were found in soil, including seven species in the Acaulosporaceae. Eighteen phylotypes were amplified from grape roots with AM1 and NS31 primers, and clones were dominated by Glomus spp. (> 99%). A few clones ...
Objectives. The aim of this study was to investigate the number of roots and root canals in the maxillary second premolar in a group of Jordanian population. Materials and Methods. A total of 217 patients, 100 female (46%) and 117 male (54%), received root canal treatment of maxillary second premolar from January 2012 to January 2014. The mean age of the patients was 32.7, ranging from 18 to 60...
