Background:Personal identification plays an inevitable role in forensic investigation. Lip print is one of the evidences that can be left in the crime scene, which helps in identification purpose. Hence, the present study was undertaken to provide deeper inside view of use of cheiloscopy in personal identification, focusing on sex and age variability of lip print patterns in the population of Rajnandgaon city, Chhattisgarh, India.Materials and Methods:The cross-sectional study was conducted among 200 (100 males and 100 females) subjects of age 15-55 years, residing in different areas of Rajnandgaon city. The sex of the individual was determined as per the description given by Vahanwala et al. Frequency distribution and Chi-square test were used for data analysis by SPSS 16.0 V software.Results:The most common lip print pattern in entire population was Type I (27.5%). Very highly significant difference was found in the distribution of lip print patterns among males and females in the entire population, group I, and group III, respectively (P < 0.0001). The overall accuracy of cheiloscopy in sex determination was (high) 87.95%, 87.65%, 90.5%, and 80% in group 1, 2, 3, and 4, respectively.Conclusion:Thus, it can be concluded that lip prints can be used as one of the important forensic tools for personal identification on the basis of their age and gender variability among the populations.
Aim: There is growing evidence that periodontitis may affect general health. This study was assigned to explore changes in cholesterol levels following nonsurgical periodontal therapy in patients with chronic periodontitis.
Materials and methods:Periodontal parameters and lipid profile (total cholesterol, high-density lipoprotein, low-density lipoprotein, triglycerides and very low-density lipoprotein) were evaluated in 50 subjects suffering from moderate to severe generalized chronic periodontitis.Results: At third month, there was significant reduction in total cholesterol, low density lipoprotein, very low density lipoprotein, triglyceride and increase in high density lipoprotein after nonsurgical periodontal therapy (NSPT). Also, the reduction in bleeding on probing, pocket depth and attachment level were statistically significant in the treatment group.
Conclusion:The results of our study showed that periodontal destruction and serum lipid levels are positively correlated and nonsurgical periodontal treatment in chronic periodontitis patients resulted in significant changes in the concentration of total cholesterol, triglycerides, HDL, LDL levels in blood serum.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
