Orthodontic pain control following arch wire placement; a comparison between pre-emptive tenoxicam and chewing gum: a randomized clinical trial.

Background: Pain during fixed orthodontic treatment can have a detrimental effect on patient treatment compliance. To overcome this, there is a definite need to establish the best pain-relieving methods suitable for orthodontic patients in terms of efficacy and use. The objective of this study was to compare the effect of chewing gum and pre-emptive tenoxicam on pain after initial archwire placement and to evaluate the pain perceptions of orthodontic patients in the two groups while performing various functions at specific time intervals.

Comparison of stress distribution in teeth restored with fiber post and dentin post by applying orthotropic properties: A three-dimensional finite element analysis.

Aim Of The Study: We aimed to compare stress distribution in a tooth restored with fiber post and dentin post after applying the orthotropic properties using three-dimensional finite element analysis (3D-FEA).

Materials And Methods: Two 3D-FEA models were constructed. The material properties were assigned, and a load of 100 N was applied at 45° to the long axis of the model onto the lingual surface incisal to the cingulum.

Rehabilitation of a mutilated maxillary central incisor using autogenous dentin post.

Ideal coronal restoration that provides satisfactory esthetic and functional outcome for endodontically treated and extensively damaged teeth is still an arduous task for restorative dentistry. None of the available post systems have all the ideal biological and mechanical properties. Biological dentin posts are considered as a good alternative to conventional post systems as they preserve dentin walls, which results in better distribution of forces along the root surfaces in the compromised tooth.
