1. 1. Shear Bond Strength of Composite to Dentine with Various Adhesive Systems

   University essay from Umeå universitet/Institutionen för odontologi

   Author : Edvin Besic; Simon Norstedt; [2023]
   Keywords : ;

   Abstract : ABSTRACT  Background Different dental adhesive systems are used in modern restorative dentistry. Older adhesive systems such as etch and rinse systems of generation 4 have been extensively tested and proven reliable, newer adhesive systems such as self-etch systems of generation 7 and 8 have been developed with the aim of improving bonding performance, durability and to be less technique sensitive.

4. 3. Exploring the physiological variables of oxygen isotope composition in chondrychthyan teeth

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för organismbiologi; Uppsala universitet/Evolutionsbiologi

   Author : Carlos Oliveira; [2019]
   Keywords : chondrichthyan; oxygen; isotope; fractionation; teeth; enameloid; dentine;

   Abstract : Since the discoveries of vertebrate bioapatite’s ability to record oxygen isotopecomposition of ambient seawater were made (Kolodny, 1983), oxygen isotopes have beenwidely used as a climatic and oceanographic proxy. The δ18OP aquatic vertebrate apatite isa function of the δ18Ow value of the ambient water, yet “vital effects” on the δ18OP compositionhave been reported previously (Venneman et al. READ MORE
