Background: Biopsy is a critical procedure in the diagnosis and treatment plan of surgical cases and is also highly technique-sensitive. Various biopsy techniques are conventionally used with each technique having its own pros and cons. A study was carried out to compare scalpel versus Punch for biopsy of oral lesions under various parameters vital to histopathological diagnosis. Materials and Methods: A total of 16 patients (08 in each group) satisfying the inclusion criteria were randomly allocated using odd-even scheme into scalpel and Punch groups by a operator. The patients were evaluated intraoperatively for patient comfort, bleeding, time taken for excision, and postoperatively for pain and healing. The excised samples were sent for histopathological analysis as follows: Loss of architecture in epithelium, loss of architecture in connective tissue and artifacts. Results: The mean time taken for excision was statistically similar in both the groups. Distribution of patient comfort and pain was statistically not significant. Healing was uneventful in both the groups. In the histological parameters, there was loss of architecture in epithelium in many cases in the punch group. In the same group, there was loss of architecture in the samples. Conclusion: Both techniques seem to be equally effective in performing incisional biopsies of oral lesions. Punch biopsy has the advantage of fast and avoidance of suturing as well. However, due to the Size of tissue caused, there may be minor loss of histological architecture.

Aesthetics is a major concern for dental patients and is a challenge in contemporary dental rehabilitation for clinicians and dental technicians. Discolored frontal maxillary teeth can result in excessive psychological suffering for the affected individual. Here we describe the use of zirconia CAD/CAM restorative materials for the treatment of teeth in the aesthetic zone for a 26-year-old teacher. Maxillary central and lateral individual zirconia crowns were manufactured and cemented with dual-cure resin cement. Harmony with the existing shade of all teeth was achieved. The patient reported improved self-esteem and better relationship with their students as well as social interactions.

On January 16, 2021, Free vaccination against COVID-19 get the ball rolling in India and the government is expected to be the largest vaccination lay out in the world and pleading all of its citizens to be immunized. Four of the eight COVID-19 vaccines currently undergoing clinical trials in India were created there. Covishield (the Oxford-AstraZeneca vaccine) and Covaxin, a home-grown vaccine produced by Bharat Biotech, have been licenced for limited emergency use by India's medicines authority. Manufacturers in India have said that they will be able to meet the country's future COVID-19 vaccination needs.

The subject of classification is taken into account to be monotonous by the majority. Classification systems help to assemble similar disease phenotypes in more homogeneous syndromes. Over the years, various researchers have done extensive work in the development of classification of periodontal diseases. Though we have made great strides towards the understanding of periodontitis in general, the bitter truth is that we have not hit the bull's eye on the true nature of etiopathogenesis. Until then any classification based on infectious etiology would be a misfit. A classification that is easy to understand and based on treatment needs would be more apt at this juncture. This article is aimed at discussing the American Academy of Periodontology 1999 and present 2017 the World Workshop Classification Systems to know and simplified the modifications.
