Following death various changes occur in the human body known as postmortem changes. These postmortem changes begin at molecular level which can be noted microscopically and finally grossly. Postmortem interval (PMI) is the time elapsed since death. Estimation of time since death is still a difficult task even for an experienced forensic pathologist. Gross changes within human body which occur following death during the postmortem interval have been routinely used to estimate the time of death considering different conditions. However, histological changes of skin and oral mucosa which occur during the postmortem interval have occasionally been used to estimate the time of death under different conditions. Objective: This study is done to study the histological features of decomposition at cellular level in postmortem oral mucosal tissue, skin and its appendages. Method: Electronic and hard data is searched and studied to understand the postmortem changes of oral mucosal tissue and skin and its appendages. (regarding cases studied number have placed in discussion). Results: Studies conducted for morphological changes of skin and its appendages showed focal dermal-epidermal separation, eccrine duct necrosis, and dermal degeneration. Oral mucosal different cellular changes like homogenization and eosinopilia, cytoplasmic and nuclear vacuolation, chromatin clumping, pyknosis of nuclei was noted at different time intervals. Conclusion: PMI determination is essential for narrowing the fields of suspects or possible missing persons. Histological examination of oral mucosa may be helpful in establishing the Postmortem interval more precisely. PMI determination is essential for narrowing the fields of suspects or possible missing persons. © 2014, Indian Journal of Forensic Medicine and Toxicology. All rights reserved. Source

Preventive dentistry is the area of dentistry that focuses on those procedures and life practices that help people to prevent the beginning or progression of oral disease. It includes at-home dental care performed by patients, as well as dental care and education by professional dental staff in the office or clinic. To assess the knowledge & utilization of preventive dentistry procedures among parents. A household survey was conducted on mothers of school children belonging to 6 to 10 year's age. A multistage sampling is used to include 800 in the study. Results: 91.13% of subjects are aware of importance of primary dentition and permanent dentition but not aware about preventive dentistry procedures to maintain the oral health. The information about the self utilizable preventive measures was obtained mainly by the media. Knowledge of preventive dentistry procedures and utilization rate among parents is very less. Less than 30% of the parents know about Preventive dentistry procedures. Source

Oral Cavity within the humans is beginning of digestive system which plays a significant role in communication. Since, of many chromogenic microorganism teeth that are enclosed within the oral cavity is subjected to various means of exogenous and endogenous substances which can stain the teeth. Appearance of pink teeth is commonly noted after death has occurred. This phenomenon is commonly noted by forensic dentists who usually visit for exhumation. Application of pink teeth in forensics as a possible means for evaluating the cause of death is limited. With the recent advancement in science and technique many research have been carried to know the etiology, biochemicals and also mechanism behind the appearance of pink color. These paper review the literature regarding the postmortem “Pink Teeth Phenomenon” and provides an insight into ante mortem staining of teeth which enables the forensic dentists to differentiates between Pink teeth Phenomenon and Antemortem Teeth Staining. © 2015, Indian Journal of Forensic Medicine and Toxicology.

Infection control is the discipline concerned with preventing nosocomial or healthcare-associated infection, a practical sub-discipline of epidemiology. It is an essential, though often under recognized and under supported, part of the infrastructure of health care. Hence the objective of the present study was to assess perception & practice of infection control measures among healthcare workers in district government hospital of Tumkur. Methodology: A cross sectional study was conducted among hospital employees using a pretested questionnaire which had four domains. Results: 78.5% of health care workers had knowledge about sterilization procedures for infection control and regarding the sterilization procedures used. When observed for practice had many lacunae's. Conclusion: Knowledge towards infection control procedures was goo but attitude as well as practice was very poor indicating the need for motivation & training. © 2016, Indian Journal of Public Health Research and Development.

Hard tissue of human dentition like enamel, dentin and cementum has been used as an essential tool in establishing the age of an individual. Recent studies show tooth-cemental annulations as a reliable tool in establishing the age of an individual. Counting the cemental annulations using phase contrast microscopy is found to be more reliable for age determination in the field of forensic medicine. Objective: Purpose of study to know the reliability of cementum annulations and phasecontrast microscopy method in establishing the age of the human being. Material and methods: 30 mandibular first premolar teeth were obtained from 30 deceased individuals (15 were unidentified & 15 were known age group) at autopsy. Consent was obtained from medical officer, kith and kin of deceased. All the 30 teeth were washed in running tap water and stored in 10% formalin. Cross sections were prepared manually from middle third of the root. These sections were mounted on a slide using DPX mountant and then viewed under a phase-contrast microscope. Results: The data obtained was analyzed using Z-test and Karl-Pearson coefficient which showed no statistical significant difference between calculated age and actual age and there was a strong correlation between estimated age and calculated age. Conclusion: Present study showed cemental annulation with phase contrast microscopy to be highly significant method in establishing the age of the individual. © 2014 South India Medico-Legal Association.
