Root development: new meanings for root canals?
During Arabidopsis root development, a radial pattern of tissues is extended by the meristem. These tissues form continuous layers and recent data suggest that tissue continuity is instrumental for constraining the direction of signaling in a process termed channeling. In the ground tissue, fate-determining signals originate from contiguous cells of the same layer, possibly due to specific symp...

متن کاملCultivable Anaerobic Microbiota of Infected Root Canals
Objective. Periapical periodontitis is an infectious and inflammatory disease of the periapical tissues caused by oral bacteria invading the root canal. In the present study, profiling of the microbiota in infected root canals was performed using anaerobic culture and molecular biological techniques for bacterial identification. Methods.

متن کاملilling Root Canals in Three Dimensions
OE — Volume 32, Number 4, April 2006 he final objective of endodontic procedures should be the total obturation of the root canal space. Biologic necessity requires the elimination of the protein degradation roducts, bacteria, and bacterial toxins which emanate from necrotic and gangrenous oot canals. While these irritants may be eliminated by extraction of the tooth, the health f the dentition...
متن کاملBiofilm formation in medicated root canals.
The hypothesis that Enterococcus faecalis resists common intracanal medications by forming biofilms was tested. E. faecalis colonization of 46 extracted, medicated roots was observed with scanning electron microscopy (SEM) and scanning confocal laser microscopy. SEM detected colonization of root canals medicated with calcium hydroxide points and the positive control within 2 days. SEM detected ...
