This study shows that CPP-ACPF varnish is effective in preventing demineralization as well as promoting remineralization of enamel. Thus, it can be used as an effective preventive measure for pediatric patients where compliance with the use of tooth mousse may be questionable.

Grossing and microscopic examination of the received specimens in a histopathological laboratory is a routine procedure for achieving a fi nal diagnosis. Errors in either of the steps may lead to an inaccurate diagnosis since wrong orientation of the specimen may either cause diagnostic delays or pose a diagnostic dilemma. Stereomicroscope is an important accessory instrument which can be used to study a variety of specimens. It not only enables us to study the surface details but also aids in minute work including dissection and microsurgery to name a few.Aim:To assess the effectiveness of stereomicroscope in routine grossing and its role in arriving at a final diagnosis.Materials and Methods:Cases from the archives of the department for which stereomicroscopic evaluation was done were retrieved and reviewed.Results and Conclusion:Stereomicroscopic images aided not only in the proper orientation of the specimen but also in the diagnosis.

Objective: Oral exfoliative cytology is a sensitive and reliable diagnostic tool for the early diagnosis of oral cancer. Traditional exfoliative cytology, though popular, has limitations which could be overcome using cytocentrifuge preparations. The purpose of this study was to compare the efficacy of cytocentrifuged specimens with that of conventionally prepared smears in the diagnosis of oral premalignancy and malignancy. Study Design: Exfoliative cytology was performed on 30 patients with oral premalignant and malignant lesions. The yield was smeared immediately onto a slide for conventional exfoliative cytology (group A). The lesion was then scraped again and the yield was suspended in a bottle containing a fixative solution for cytocentrifuge apparatus-assisted smearing (group B). Both smears were stained with rapid Papanicolaou stain and assessed for cellularity, cellular and nuclear morphology, evaluation of mitosis and background. Result: All the criteria assessed were statistically significant (p value of <0.001) in group B except for mitosis, which was significant in group A. Conclusion: Cytocentrifuge preparations can preserve the cellular details and reduce the overlapping of cells, enabling precise interpretation and thus aiding in the diagnosis of premalignant and malignant lesions of the oral cavity.

1.5% of ethanolic husk extract of C. nucifera has a significant antibacterial action against polymicrobial dental biofilm and its activity is comparable to that of 2% CHX which validates its use as a future irrigating solution for overcoming bacterial resistance with synthetic agents.
