Background: India Ink is the most commonly used ink in surgical pathology. The main disadvantages of India Ink are longer drying time, monochrome, toxicity and cost. Because of these disadvantages, alternative materials have been suggested to replace India ink. The aim of this study is to evaluate the effectiveness of nail enamel for inking of surgical margin and to compare it with India ink. Materials and methods: N = 20, which included 10 mucosal and 10 skin samples. Each selected margin is divided into 2 equal halves and one is inked with India ink and the other with nail enamel (Vernis A Ongles: Dark green). After routine processing and staining, the effectiveness of nail enamel and India ink were compared based on macroscopic and microscopic parameters. Results: Less drying time and visibility on paraffin wax block were excellent for nail enamel. Microscopic visibility of nail enamel was comparable with that of India ink. However, processing fluids contamination is the main drawback of nail enamel. Conclusion: Nail enamel can be used as an alternative to India ink because of its less drying time, ease of application, good visibility on wax blocks and microscopically, availability in multiple colours, cost effectiveness and non-toxicity.
Background: Mandibular projective ramus height is one of the accurate parameters in age estimation.Estimation of age by mandibular ramusheight using various digital softwares is one of the newest approach in forensic dentistry. The aim of the present study is to derive a new linear regression formula for estimating age of south Indian population using mandibular projective ramus height.
Materials and Methods: This retrospective study included OPG samples n=260 from 5 age groups between 30 to 79.9 years. Measurement of mandibular projective ramus height was done using Planmeca Romexis Viewer software and tabulated and exported to SPSS software for linear regression analysis.
Results: Mean mandibular projective ramus height value of males (28.7) is higher compared to females (27.3) in all age groups and there is also a significant decrease in mandibular projective ramus height in both gender as the age advances. The gender specific and general linear regression formula derived for estimation of age in the South Indian population.
Conclusion: Even though the current linear regression formula for estimating age carries 65% accuracy, further research with adequate sample size should be carried out across the hospitals in Chennai for more significant and region specific results.
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.
