Penetration of resin into experimentally formed infractions in porcine tooth crowns
Lamella Resin Tooth infractions Trauma
2008/11/11
Tooth infractions are regarded as possible pathways for microorganisms and other pulpal irritants in gaining access to the dental pulp; hence, these defects must be sealed to prevent subsequent pulpal...

2008/4/16
Five cases of delayed eruption of the first molars due to immature tooth formation are presented. Three cases involved a teeth in a single quadrant, two of which were the maxillary left region while t...
Measurement of bone conduction characteristics for transmitted vibration sounds of tooth drilling
Air turbine handpiece Audition characteristic Bone conduction Frequency characteristics Micro motor handpiece
2008/4/16
PURPOSE: In this study, we measured the vibration caused during dental treatment by an air turbine handpiece and a micro motor handpiece. We then analyzed the obtained data to develop a method for noi...
Research on the remineralization of partially decalcified enamel surfaces using extracted tooth with calcifying solution
Apatite FT-Raman Remineralization Tooth enamel X-ray diffraction
2008/4/16
OBJECTIVE: The recovery of tooth enamel after acid etching was examined in vitro using enamel powder in order to maximize the contact surface area. METHODS: The weight of the powder decreased due to a...

The effect of xylitol and fluoride on remineralization for primary tooth enamel caries in vitro
Fluoride Primary tooth Remineralization Xylitol
2008/4/16
The effect of fluoride and xylitol on remineralization at the early stage of the enamel caries in primary tooth was studied. The samples were divided into four groups (control, 10% xylitol, 950 ppm Na...
