Stress Propagation in the Craniofacial Skeleton on Frontal Impact-A Virtual Simulation Study.

Background: The research paper emphasizes on virtual simulation of craniofacial skeleton to understand its Biomechanics.

Methods: In this study, a 3D finite element model of the skull was created using CT scan data. All complexities of the skull geometry are simulated using ABAQUS software.

A comparative evaluation: Oral leukoplakia surgical management using diode laser, CO2 laser, and cryosurgery.

Background: The comparatively evaluate the three surgical treatment modalities namely cryosurgery, diode and CO2 laser surgery in terms of healing outcomes on the day of surgery, first and second week post operatively and recurrence at the end of 18 months was assessed.

Material And Methods: Thirty selected patients were divided randomly into three groups. Each group comprising of ten patients were subjected to one of the three modalities of treatment namely cryosurgery, diode laser or CO2 laser surgery for ablation of OL.

A Comparative Study of Post-traumatic Stress Disorder, Anxiety, Depression and Change in Sexual Functioning of Patients with Facial Injuries and Patients with Extremity Injuries.

Background: This study was performed to identify and compare the presence of and the levels of post-traumatic stress disorder (PTSD), anxiety, depression and if any change in sexual functioning is present in patients with disfiguring facial injuries, nondisfiguring facial injuries and visible extremity injuries.

Materials And Methods: A total of 378 patients from multi modal trauma centers in Bengaluru city were included for the study. A total of 153 patients were those who had disfiguring facial injuries, 111 patients with nondisfiguring facial injuries and 114 patients had sustained a visible extremity injury that was not covered by clothing (disfigurement /scarring).

An Analysis of the Stress induced in the Periodontal Ligament during Extrusion and Rotation Movements- Part II: A Comparison of Linear vs Nonlinear FEM Study.

Background: Optimal orthodontic forces are those which stimulate tooth movement with minimal biological trauma to the tooth, periodontal ligament (PDL) during and alveolar bone. Among various types of tooth movements, extrusion and rotational movements are seen to be associated with the least amount of root resorption and have not been studied in detail. The mechanical behavior of the PDL is known to be nonlinear elastic and thus a nonlinear simulation of the PDL provides precision to the calculated stress values.
