تاثیر افزایش طول ریشه دندان بر بروز آلودینی سرمایی ناشی از فشار بر عصب دندانی و درجه‌بندی مقایسه‌ای آن با بهره‌گیری از تکنیک چاپ سه بعدی سی‌تی اسکن و رادیوگرافی در خرگوش,‮‭Effect of dental root elongation on dental nerve compression induced cold allodynia and its comparative grading by ۳d computed tomography printing and radiography in rabbit‬

Text of Note

Objective: . The aim of this study is to compare the results of grading by radiography, CT and 3D printing and also evaluation of Effect of dental root elongation on dental nerve compression induced cold allodynia Methods: Eight adult domestic rabbits with dental disease used for this study. At first,cold allodyna test was performed on rabbits with soaked in cold spray swab. After radiographic examination, rabbits were anesthethised and then ct was performed and finally 3D printing obtained from StereoLithography(STL) format. The Kruskal-Wallis nonparametric method was used to investigate the grading methodes using the R 3.5.2 software. Results: The cold allodynia test was negative for all rabbits. CT grading with the highest degree of detection (3.375) had a significant difference and a higher accuracy than radiographc grading(2.75), and 3D printing grading(3). (p <0.05). The results of the Kruskal-Wallis test showed that despite the higher diagnosis degree in the 3D printing compared with the radiography, the significant didnt exist. Conclusion: This study showed that CT is a more accurate method than radiography and 3D printing to grading the dental disease in rabbits Also, CT could provide more details about the extent of the disease However radiography and 3D printing provided good information also cold allodyna test was not a good test to diagnose pain in rabbit incisor teeth
