Abstract

Background: Apart from being part of the clinical diagnostic tool various imaging techniques help in understanding the brackets and other biomaterials used in orthodontics at a microscopic level. The aim of this study was to find chair side alternative to one such imaging technique in evaluating the bracket dimensions (slot height, mesh design, torque) and Adhesive Remnant Index using stereomicroscope.  Methods and Material: Images of 10 central incisor brackets, Seven 2nd premolars buccal surfaces after debonding procedure were taken using a lens attached to Smartphone camera. The images were then calibrated and measured using ImageJ software. Results: The images of the brackets and the tooth surfaces were taken with three combinations of lenses. The clarity of the images taken was sufficient to accurately measure the slot height, torque and to estimate the Adhesive Remnant Index. The analysis of the images showed that the dimensions of slot height, torque were within the range as prescribed by MBT. Conclusions: The present method of taking the images with Smartphone offers an invaluable alternative to the images obtained from stereomicroscope to a limited magnification.
