@article{Budiman_2016, title={Comparing Methods for Dental Casts Measurement}, volume={4}, url={https://ajouronline.com/index.php/AJAS/article/view/3693}, abstractNote={<p>Traditionally, conventional dividers and sliding calipers, analog or digital, have been used to measure dental casts manually. Today, several digital methods are available for measuring tooth size. The digital methods of measurements were gathered by transforming the 3D dental plaster casts into 2D form. Scanners, Photocopy machine, Digital camera are means to make this transformation. OBJECTIVE: This research was to find out which method of dental casts measurement is the best accuracy and reliability. METHOD: Mandibular dental casts of 10 patients, mixed gender, taken after finishing orthodontic treatment were formed by using 3 different dental stones color. The variables (tooth size, intercanine width, intercanine depth, intermolar width, intermolar depth) were measured using 7 methods. All data were analyzed statistically. Anova, followed by independent t-test, were applied to test the difference of variables measured in sexes, colors and methods. Alpha Cronbach was used to test the reliability among methods. To compare the accuracy among methods, we applied sensitivity, specificity and ROC test of variables among methods. Regression analysis was applied for several variables that showed significantly different (p<0.05) as a result of different measurement methods compared to gold standard. RESULT: Colors did not play important role for the result of measurement gathered from different methods. Sexes should be considered taking part for different value of measurement. CONCLUSION: 3D measurement still gave the best measurement result, despite the difficulties in handling the dental casts. With some mathematical equations derived from regression analyses, 2D measurement could give almost the same result as 3D measurement.</p>}, number={2}, journal={Asian Journal of Applied Sciences}, author={Budiman, Johan Arief}, year={2016}, month={Apr.} }
