RESUMO
Lead is a dangerous element that exists naturally in the Earth's crust. Any kind of lead causes a detrimental response in the human body. It is discharged into the environment during the manufacturing of batteries, foundries, ammunition, lead paint, water pipes, and other manufactured goods. It can enter the body through a variety of pathways, including those in the air, water, soil, food, and dust. Concern is raised since there is no amount of lead that is safe for the human body. The problem persists despite several prevention measures that the state and the federal governments have put in place. This review assesses the effects of lead exposure on children as well as suggested solutions to the issue.
RESUMO
Background- The malignancy of the oral cavity constitutes the most important group of malignancies in South and Southeast Asia.The risk increases with the use of tobacco products. Materials & Methods- Micronuclei frequency scoring was used as a biomarker to identify different potentially malignant disorders. Results- Mean micronuclei index was found higher using Hematoxylin and Eosin stain than Papanicolaou's stainand May Grunwald's stain. Conclusion- We concluded that the micronuclei frequencies in oral exfoliated epithelial cells using three different stains- Hematoxylin and Eosin stain, Papanicolaou's stain, May Grunwald's stain may be useful in predicting the malignant potential of premalignant lesions.
