Research Paper (postgraduate) from the year 2007 in the subject Medicine - Dentistry, University of Mosul (Dental college), language: English, abstract: Aims: To evaluate the effects of the micro-etching procedure on the bracket's slot and base parametersand on the tensile bond strength of the recycled brackets. Materials and Methods: The sample was 20stainless brackets grouped into; control brackets group(10) and de bonded brackets group(10). The de bonded brackets reconditioned with micro etcher. the data subjected to the statistical analysis at = 0.05significant level. Results: demonstrated that the use of micro etcher for recycling the de bonded bracketsdo not affect the bracket s slot and base parameters whereas affected the bond strength of the recycledbrackets. Conclusion: The micro etcher (sand basting) is recommended for recycling the de bondedstainless steal brackets and reuse them in orthodontic treatmentsKey words: Orthodontic brackets; micro-ether; recycling.
