Ergonomics can be defined as a discipline that studies workers and their relationship to their occupational environment. To prevent musculoskeletal disorders which can develop over time and can lead to long-term disability proper ergonomic design is necessary. Periodontal work covers most of the areas in the oral cavity including distal aspects of posterior teeth which are difficult to approach. Hence preventing work related strain was of greater significance in ensuring long term successful practice as a periodontists. The purpose of this survey was to assess the knowledge attitude and practice of ergonomics and musculoskeletal disorders as an occupational hazard in periodontists in India .A survey was conducted among 150 periodontists in India in which 120 periodontists responded. The survey was distributed through questionnaire printouts and electronic media. The data was collected, analysed and interpreted. The results suggested that 85% of the periodontists had adequate knowledge and attitude towards ergonomics, however the practical application was not as satisfactory. This survey concludes that the knowledge and attitude of periodontists in India regarding ergonomics and musculoskeletal disorders as an occupational hazard is good overall, but the practice is needs some improvement.

Aim of the present study is comparative evaluation of the inherent antimicrobial properties of the copper and stainless steel suction tube also evaluate bacterial adherence and reduction with time within the suction tube. Present study was performed in an in vitro setting in Saveetha dental college and hospital. Both the metals suction tubes were cut into equal lengths of 2.3 inches and dipped in a sterile container for 5 minutes which had bacterial suspension of Streptococcus Mutans. Each group included three samples of copper and stainless steel suction tubes. Control group was taken out at 0 mins post initial dipping period de-coated in a sterile container and immediately cultured on Brain heart infusion agar, followed by group 1 at 15 minutes group 2 at 60 minutes and group 3 at 180 minutes respectively. Bacterial colonies were counted after overnight incubation. Copper suction tubes demonstrated less initial adhesion of bacterial colonies than that of stainless steel suction tubes. Percentage reduction in bacterial colonies was observed more in stainless steel suction tubes with respect to time. Spite of high initial adhesion stainless steel suction tube demonstrated higher degree of percentage reduction in bacterial colonies with time hence proven better for antimicrobial properties than copper suction tube.

This article aims to present a report of an atypical clinical presentation of a plasma cell gingivitis (PCG) case with unusual skin lesions. PCG is a rare benign inflammatory condition which can be classified into Type 4 hypersensitivity reaction. It occurs due to reaction to unknown antigen, often flavoring agents or spices found in chewing gums, toothpastes and lozenges. Histologically, the lesion shows dense plasma cells infiltrate in the connective tissue. Early diagnosis of PCG is essential to differentiate from variety of conditions, namely, leukemia, HIV infection, discoid lupus erythematosus, atrophic lichen planus, desquamative gingivitis, or cicatricial pemphigoid which must be differentiated through hematologic and serologic testing. In this article, we will discuss a case of PCG with unusual skin lesions.

Aim of the study is to determine the prevalence of gingival black triangles (GBT's) and its correlations with the morphology of tooth, labial frenum and probing depth in young adults in the Chennai population. The study was carried out in a university based study setting in Saveetha dental college and hospital among the Chennai population. We have reviewed patient records and analysed the data from 86000 patient records between June 2019 and March 2020. 149 samples were randomly selected for the study (18 – 30 yrs) and photographic analysis from the patient record was carried out to determine the presence of GBT. Prevalence of GBT was found to be 20.8% in the selected population. Within the limits of the study prevalence of GBT was found to be 20.8% there should be more emphasis given on creating awareness about the condition and its possible treatment modalities.
