Effects Of Different Tooth-Conditioning Agents On Bond Strength Of A Resin-Modified Glass-Ionomer Cement To Enamel, Ahmed Alammary
Al-Azhar Journal of Dentistry
The purpose of this study was directed to evaluate the effects of different toothconditioning agents on shear bond strength of resin-modified glass– ionomer cement(Fuji III LC) to enamel as well as on dissolution of calcium ions from the enamel surfaces.Methods. The enamel surfaces of lower incisors were treated with 10 and 20%polyacrylic acid, 12% citric acid and 35% phosphoric acid for 20s. Fuji III LC wasapplied to the etched enamel surfaces, and the shear bond strength of each specimenwas measured using an Instron Universal Testing Instrument. The amounts of calciumions dissolved from the treated enamel surfaces were also measured using …

Relationship Of Facial Measurement For Determining The Vertical Dimension In Young Adult Saudi Students, Nehad Harby
Relationship Of Facial Measurement For Determining The Vertical Dimension In Young Adult Saudi Students, Nehad Harby
Al-Azhar Journal of Dentistry
There is no specific scientific method for determining the correct edentulous occlusal vertical dimension. In this study, the establishment of the proportion between the ear-eye to chin-nose distance to determine occlusal vertical dimension.200 dentulous Saudi students participated in this study. The chin-nose and eareye (right & left) distances were measured; the results showed that there is a correlation between these measurements; also this study showed that this facialmeasurement may be used to predict chin-nose distance and determining occlusal vertical dimension in edentulous patients of the Saudi population in combination with some other methods, which have proved to be helpful
