1. Purpose and references 1.1 Purpose of study
This study is planned for the selection of biocompatibility test for Core it Dual. The purpose of this assessment is to ensure that no undue risks arise from biological hazards associated with materials of manufacture and final devices.
Most of the contents are prepared by being referenced the following standards.
1) Guidance on biocompatibility assessment - The medical device agency on 1997 2) ISO 10993-1 : 2003 Biological evaluation of medical devices - Part 1 : Evaluation and testing 3) ISO 10993-4 Part 4: Selection of tests for interactions with blood
4) ISO 10993-5 Part 5: Test for in vitro cytotoxicity
5) ISO 10993-10 Part 10: Tests for irritation and delayed-type hypersensitivity
6) ISO 10993-11 Part 11: Test for systemic toxicity
Core it Dual is dual-cured composite resin designed for the fabrication of all kinds of core build-ups & build-up fillings. It has the characteristics of good depth of polymerization, high compressive strength, and radiopaque. Core•it has various shades (Blue, yellow).
1) Common name : Core Build up Resin 2) Proprietry name: Core it Dual
