Context: Lichen planus is an idiopathic chronic inflammatory mucocutaneous disease that frequently involves the oral mucosa and skin. It has been proposed that psychological factors like high stress and anxiety levels have a strong association with lichen planus. Estimation of the stress level in patients with oral lichen planus. Aims: To estimate the stress in patients with Oral Lichen Planus by Hospital Anxiety and Depression Questionnaire, Depression Anxiety Stress Scale 21, and State-trait anxiety inventory and compare these with normal healthy individuals. Methods and Material: Twenty oral lichen planus patients and twenty normal subjects were included in the study. Every individual gave the hospital Anxiety and Depression Questionnaire, Depression Anxiety Stress Scale 21, and State-trait anxiety inventory. Statistical Analysis Used: Data obtained were analyzed with SPSS software 26. The findings of various parameters were evaluated and analyzed statistically using Mann Whitney U test. Results: Hospital Anxiety and Depression Questionnaire, State-trait anxiety inventory, Depression Anxiety Stress Scale 21 scores were significantly higher in the oral lichen planus group than in normal individuals. Conclusions: Psychological factors like anxiety and depression play a major role in the pathogenesis of OLP, and non-invasive procedures like the Hospital Anxiety, and Depression Questionnaire, Depression Anxiety Stress Scale 21, and State-trait anxiety inventory scores can be used as a useful indicator to estimate stress levels in OLP patients.

Introduction: The importance of Cone Beam Computed Tomography (CBCT) in the field of Implant Planning is a rapidly emerging imaging modality for the purpose of implant planning. Having the obvious benefits over the conventional methods of radiography, CBCT by far is the most promising aid in the efficient implant-supported prosthetic field. Aim: The present study aimed to evaluate the bone density and the height and width around dental implants and compare it to that of the edentulous space before placing the implant. Materials and Methods: A longitudinal study was conducted in the Department of Oral Medicine and Radiology of Kalinga Institute of Dental Sciences, Bhubaneswar. A total of 20 subjects from the CBCT database of the department with a single posterior edentulous space indicated for implant-supported dental prosthesis were selected. Approval of the Ethical Committee was taken. A pre-implant radiographic assessment was done with the help of CBCT, to evaluate the crestal height, crestal width and bone density, followed by surgical placement of the implant. After 6 months of implant placement, a post-operative radiographic assessment was done to evaluate the same parameters.  Results: The mean difference of pre- and post-implant crestal width was 0.57 (p<0.001), crestal height was 0.5 (p<0.001) and bone density was 58.2 (p<0.001). It was observed that the mean crestal height, width and bone density was higher in the post-operative radiographic assessment compared to the pre-operative radiographic assessment and the difference was statistically significant. Conclusion: From the given results, it can be concluded that alveolar bone width, height and bone density were significantly improved after implant placement and the osseointegration occurring after implant prosthesis greatly improves the periodontal status of the peri-implant tissues.
