Entry for:2019 Pitch it Clever
Dental practitioners select tooth-coloured adhesive materials (TCAM) based on procedural simplicity, versatility and clinical research outcomes. However, TCAMs placed in teeth located in the back of the mouth fail earlier, compared with traditional restorations. TCAM failure may occur when teeth are restored without accounting for variable adhesive mechanisms and tooth properties. TCAMs such as Glass Ionomer (GIs) Cements, Self-etch Adhesives (SE) and Etch and Rinse (E&R) products adapt variably to the second layer of tooth, dentine. Dentine collagen and mineral properties can vary with patient age, depth and site. Therefore, an understanding of age and site-specific dentine mineral and collagen variation is fundamental to adapt TCAMs successfully. However, changes to dentine properties and the consequent effects on TCAM-tooth micro-interactions remain relatively unexplored. Therefore, the aims of my project are to
1. Determine the effect of tooth site and patient age on dentine collagen and mineral characteristics.
2. Determine the effect of cavity location and depth on dentine bonding.
