Here we report multiple lamniform shark teeth recovered from fluvial sediments in the (Campanian-Maastrichtian) Cerro Fortaleza Formation, Santa Cruz Province, Argentina. This small tooth assemblage is compared to various ...
IgG4-positive plasma cells are more often detected in chronic periapical lesions arising from permanent rather than primary teeth
(2021-05-01)
Aim: To characterize plasma cell subsets in chronic periapical lesions affecting permanent and primary teeth. Methodology: Only chronic periapical lesions without root canal treatment were selected. Twenty-one radicular ...
Effect of reducing acid etching time on bond strength to noncarious and caries-affected primary and permanent dentin
(2013)
The purpose was to evaluate the effect of acid etching time on the bond strength of a simplified etch-and-rinse adhesive system to noncarious and caries-affected dentin of primary and permanent teeth. Methods: Twenty-four ...
Colour stability of acrylic resin denture teeth after immersion in different beverages
(2014)
The colour stability of acrylic resin denture teeth in beverages was investigated. A spectrophotometer measured the colour (CIE-L*a*b* system) of all specimens after storage in distilled water for 24 h at 37°C (T0). Specimens ...
Structural resistance in immature teeth using root reinforcements in vitro
(Blackwell Munksgaard, 2005-06-01)
The purpose of this study was to evaluate in vitro the efficacy of root reinforcements by light-cured composite resin or zirconium fiber post in simulated immature non-vital teeth. Fifty-six bovine incisors teeth were used ...
Histological evaluation of dog permanent teeth after traumatic intrusion of their primary predecessors
(Blackwell Publishing, 2006-08-01)
The aims of this study were to analyze the histomorphology of developing permanent teeth whose primary teeth had suffered traumatic intrusion, as well as to compare the influence of immediate extraction of the intruded ...
In vitro evaluation of the influence of air abrasion on detection of occlusal caries lesions in primary teeth
(Amer Acad Pediatric Dentistry, 2008-01-01)
Purpose: The purpose of this study was to assess the influence of cleaning pits and fissures with on aluminum oxide air abrasion system on the detection of occlusal caries in primary teeth using laser fluorescence (LF) and ...
Natal and neonatal teeth: Review of the literature
(2001-12-01)
