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 parameters and on the tensile bond strength of the recycled brackets. Materials and Methods: The sample was 20 stainless 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 = 0.05 significant level. Results: demonstrated that the use of micro-etcher for recycling the de-bonded brackets do not affect the bracket's slot and base parameters whereas affected the bond strength of the recycled brackets. Conclusion: The micro-etcher (sand basting) is recommended for recycling the de-bonded stainless steal brackets and reuse them in orthodontic treatments Key words: Orthodontic brackets; micro-ether; recycling.
