Introduction: With the availability of different post systems and various studies on the strength of teeth restored with posts, the controversy as to which post systems provide better stress distribution of post and longevity of tooth has not been resolved. The purpose of this study was to compare the stress distribution of three different post materials using finite element analysis. Materials and nethod: Three dimensional finite element models of central incisor, three posts with crown were constructed on computer with software. Posts of three different materials (Ni-Cr post, Glass fiber post, and Zirconia post)with zirconia crown were virtually generated and a force of 100 N was applied at an angle of 450 on the palatal surface of the crown. Von Mises stresses were evaluated on the cervical, middle and apical third of the root. Results: The maximum stresses were seen on the cervical one-third in each post material indicating that this region is more prone to fracture in tooth restored with posts. Among the three materials tested, Ni-Cr post showed maximum stress generation followed by Zirconia post and glass fiber post. The maximum stresses generated by the posts were 11.4 MPa, 10.58 MPa and 4.11 MPa respectively. Conclusion: The less rigid post material like glass fiber post can be used in an endodontically treated anterior teeth.

Comparison of Efficacy and Safety of Hydroxychloroquine and Teneligliptin in Type 2 Diabetes Patients who are Inadequately Controlled with Glimepiride, Metformin and Insulin therapy: A Randomized Controlled Trial with Parallel Group Design

Aim: The aim of the present study is to assess the efficacy and safety of Hydroxychloroquine in comparison with Teneligliptin in type 2 diabetes patients whose blood glucose levels were inadequately controlled with metformin, Glimepiride and insulin therapy. Methods: This was a randomized, prospective, parallel-group, experimental trial done in 300 Type 2 Diabetes patients who were uncontrolled (HbA1c=7.5–10%) with metformin, Glimepiride and insulin therapy. Patients were randomly divided into two groups one received Teneligliptin 20 mg (n=152) and other received Hydroxychloroquine 400 mg (n=148) while continuing insulin therapy with other 2 OHA. Insulin doses were adjusted to maintain normal blood glucose levels. Result: The adjusted mean change from baseline to endpoint in HbA1c was −1.2±0.5% in patient group receiving Hydroxychloroquine and −0.9±0.5% in patients group receiving Teneligliptin, respectively, with a significant between-treatment difference (p<0.001). The incidence of adverse events was similar in the Hydroxychloroquine (72%) and Teneligliptin (77%) groups. However, hypoglycaemic events were less common (p<0.001) and less severe (p<0.05) in patients receiving Hydroxychloroquine than in those receiving Teneligliptin. Conclusion: Hydroxychloroquine decreases HbA1c in patients whose type 2 diabetes is poorly controlled with high doses of insulin as compare to Teneligliptin. Addition of hydroxychloroquine to insulin therapy is also associated with reduced incidence of confirmed and severe hypoglycaemia.
