Precise diagnosis of the teeth root canal system using 3D CT

Эндодонтия Today, 2020
The quality of root canal treatment remains an important issue largely due to the structure of the root canal system. The use of cone-beam computed tomography in the practice of a dentist simplifies endodontic treatment.

aaquetzalli is required for epithelial cell polarity and neural tissue formation in Drosophila [PDF]

PeerJ, 2018
Morphogenetic movements during embryogenesis require dynamic changes in epithelial cell polarity and cytoskeletal reorganization. Such changes involve, among others, rearrangements of cell-cell contacts and protein traffic.

Development of robust antiviral assays using relevant apical-out human airway organoids

bioRxiv
While breakthroughs with organoids have emerged as next-generation in vitro tools, standardization for drug discovery remains a challenge. This work introduces human airway organoids with reversed biopolarity (AORBs), cultured and analyzed in a high ...

The effect of timing temporary cements to treat induced pulp necrosis in the teeth of dogs Uso do "curativo de demora" em diferentes tempos no tratamento endodôntico de cães com necrose pulpar induzida

Pesquisa Veterinária Brasileira, 2007
During endodontic therapy (pulpectomy, root canal debridement and root canal filling) microbiological management is a major concern. Bacteria present in dentine tubules, apical foramina and apical delta are causally related to failure of the procedure ...

Comparação entre sessão única e a utilização do "curativo de demora" no tratamento endodôntico em cães: aspectos histopatológicos e microbiológicos Comparison of the application of temporary endodontic dressing in teeth of dogs: histopathological and microbiological aspects

Pesquisa Veterinária Brasileira, 2007
No tratamento endodôntico a presença de bactérias é a maior preocupação. A presença de bactérias nos túbulos dentinários, foraminas apicais e no delta apical é considerado como falha de procedimento.

Laser technology in endodontic treatment of chronic apical periodontitis: comparative evaluation of antibacterial efficiency

Эндодонтия Today, 2020
In a modern endodontics the disinfection of infected root canals still remains a challenging problem, because mechanical removal of organic remnants and microorganisms from lateral canals and ramifications of the apical delta is impossible.
