fa Optical coherence tomography for debonding evaluation: An in-vitro qualitative study ارتودنسی Orthodontics پژوهشي Research <p> <strong>Introduction</strong></p><p>  The purpose of this research was to demonstrate the potential of the optical coherence tomography technique on the evaluation of changes and damages in the enamel structure caused by debonding and cleanup procedures. </p><p> <strong>Methods</strong></p><p>  Twin metal and ceramic brackets were bonded to the labial enamel surfaces of 120 incisors the brackets were debonded 24 hours later. The anterior surfaces of the teeth were scanned, and optical coherence tomography images were captured in 2-dimensional and 3-dimensional modes before and after debonding and cleanup. A commercial spectral domain optical coherence tomography system with a 5-μm axial spatial resolution was used. The system is based on the Michelson interferometer setup. It is connected to a preconfigured personal computer, and the images are captured with a scanner probe that controls the light beam position at the sample. A total of 960 images were evaluated. </p><p> <strong>Results</strong></p><p>  The analysis of the 2-dimensional and 3-dimensional images obtained with optical coherence tomography allows observation and evaluation of adhesive remnants, enamel damage, and superficial aspects of enamel from different methods of adhesive remnant removal. The 2-dimensional optical coherence tomography analysis allows in-depth observation of the adhesive remnant layer. </p><p> <strong>Conclusions</strong></p><p>  Optical coherence tomography can be a powerful tool for academic and clinical applications for the evaluation of debonding procedures. </p><hr><p></p><p> <strong>Source: </strong>American Journal of Orthodontics & Dentofacial Orthopedics </p><p> <a href="http://www.ajodo.org/article/S0889-5406(12)00917-1/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1723&slc_lang=fa&sid=1 Jorge César Borges Leão Filho 10031947532846008116 10031947532846008116 No Dentistry Graduate Program in Orthodontics, School of Health and Biosciences, Pontifícia Universidade Católica do Paraná, Curitiba, Paraná, Brazil Ana Karla Souza Braz 10031947532846008117 10031947532846008117 No Universidade Federal de Pernambuco, Recife, Pernambuco, Brazil Thayse Rodrigues de Souza 10031947532846008118 10031947532846008118 No Graduate Program in Pediatric Dentistry, Faculdade de Odontologia de Piracicaba, Piracicaba, São Paulo, Brazil Renato Evangelista de Araujo 10031947532846008119 10031947532846008119 No Biomedical Engineering Postgraduate Program, Universidade Federal de Pernambuco, Recife, Pernambuco, Brazil Matheus Mello Pithon 10031947532846008120 10031947532846008120 No Department of Orthodontics, Southwest Bahia State University, Vitória da Conquista, Bahia, Brazil Orlando Motohiro Tanaka 10031947532846008121 10031947532846008121 Yes Graduate Dentistry Program in Orthodontics, School of Health and Biosciences, Pontifícia Universidade Católica do Paraná, Curitiba, Paraná, Brazil; postdoctoral fellow, Center for Advanced Dental Education, Saint Louis University, St Louis, Mo
