RESUMO
To evaluate and compare the marginal leakage in class V cavities restored with three different tooth colored restorative materials using dye penetration system. Materials and methods: Thirty extracted premolars were randomly selected for this study. Standardized classV cavities were prepared and then divided into three equal groups. Group I was restored with nano filled composite, Group II was restored with hybrid composite and group III with polyacid modified composite. They were then subjected to thermo cycling, immersed in 2% methylene blue dye, sectioned and examined under stereomicroscope. Dye penetration for each section was recorded and data was analyzed. Results: Lowest micrileakage was recorded in group I and highest leakage recorded in Group III.Conclusion: Nanofilled composite resins provide a better sealing than hybrid and polyacid modified composites.
RESUMO
Medicinal plants play a key role in human life as they are helpful in curing several diseases. They not only support health by the pharmacological nature but also utilizable as contraceptive options. The present study reveals that the medicinal plants Melia azedarach and Dodonaea viscosa leaf extracts showing antifertility activity. The decreased sperm count and reproductive organ weights including the necrotic changes in the seminiferous tubules of testis suggesting the antifertility activity of the plants. Serum glutamic oxaloacetic transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT) and other serological studies were also carried out to know whether side-effects of the extracts.
