(2004-04-01)
The dentifrices currently available in the marketplace contain many anticariogenic substances, fluoride and abrasives aimed to better clean the dental surface, remove dental plaque, improve salivary flow and its buffer ...
Blood cell attachment to root surfaces treated with EDTA gel.
(2005-04-01)
Root debridement generates a smear layer which contains microorganisms and toxins that could interfere in periodontal healing. For this reason, different substances have been used to remove it and to expose collagen fibers ...
Fracture resistance of composite resin cores with or without prefabricated posts over different substrates
(2011-09-01)
The fracture resistance of endodontically treated teeth has been an obstacle to the durability of the remaining teeth and restorations. The aim of this study was to evaluate the fracture resistance of endodontically treated ...
A comparison of molar root canal preparation using stainless-steel and nickel-titanium instruments
(1999-12-01)
Fifty-four extracted human mandibular molars were embedded and sectioned at two levels. The reassembled mesial root canals were prepared with stainless-steel hand K-files (Flexofiles) and either Nitiflex or Mity nickel-titanium ...
Microleakage evaluation of pit and fissure sealants done with different procedures, materials, and laser after invasive technique
(1999-09-01)
This study evaluated the microleakage of pit and fissure sealants after different surface preparation (invasive technique and laser irradiation) and the use of different materials (fluoride resin-filled sealant, resin-modified ...
Biomarkers of fluoride in children exposed to different sources of systemic fluoride
(SAGE Publications, 2011)
There has been no comparison between fluoride concentrations in urine and nails of children exposed to different sources of systemic fluoride. The aim of this study was to compare the relationship between fluoride intake ...
Argyrophilic nucleolar organizer regions (AgNORs) in odontogenic myxoma (OM) and ameloblastic fibroma (AF)
(2001-08-29)
Ten cases of odontogenic myxoma (OM) and six cases of ameloblastic fibroma (AF) were subjected to comparative analysis by the AgNOR technique, in order to determine a possible difference in cell proliferation index between ...
A Bayesian nonparametric multiple testing procedure for comparing several treatments against a control
(2019)
We propose a Bayesian nonparametric strategy to test for differences between a control group and several treatment regimes. Most of the existing tests for this type of comparison are based on the differences between location ...
