Objectives:The objective of this study was to evaluate stress distribution in the dentin and alveolar bone created by load application on simulated endodontically treated teeth with two different esthetic posts.Materials and Methods:A finite element model was made and elastic moduli and poissons ratio of all the materials fed to the software. For both the models, a 100N force was applied on the lingual surface of the tooth at an angle of 45°. Stress concentration and distribution were evaluated and noted down for both the posts.Results:Finite element method revealed that Glass fibre post had homogenous distribution of stress whereas in zirconia post the stress was concentrated in the post.Conclusion:The present findings suggest that glass fibre post should be used in well-conserved radicular tooth structure and Zirconia post is indicated in weakened and grossly destructed tooth structure.

Purpose:To determine the efficacy of hard, liquid, and soft splints in the management of myofascial pain dysfunction syndrome.Materials and Methods:In this randomized clinical trial, 45 patients with myofascial pain were diagnosed and were randomly assigned into three groups of 15 patients each. Group 1 - subjects were given hard splint, Group 2 - soft splint, and Group 3 - liquid oral splint for 3 months. Subjective pain analysis using Modified Symptom Severity Index (Mod-SSI) and objective pain analysis muscle palpation was performed at 7 days, 1 month, 2 months, and 3 months after splint insertion. The changes in mean pain value by both methods, in all three groups, were analyzed with Tukey test and Kruskal–Wallis H-test, respectively (P < 0.05).Results:Both Mod-SSI and palpation scores showed statistically significant reduction in pain for all three groups at the end of 3 months. However, the hard splints proved to be very effective in a shorter period of time, followed by liquid splints and finally soft splints.Conclusion:The result of this study advocates the use of any one of the three types of the occlusal splints in the therapeutic management of myofascial pain due to temporomandibular disorders.
