ABSTRACT
Aim The aim is to evaluate the degree of dye penetration between a dual-cure and conventional resin cement on its application on the root surface indirect restorations to provide a reference for clinical choice. Materials and methods Ten freshly extracted human maxillary central anteriors were selected and randomly divided into two groups of five each. Teeth were prepared for veneer restoration, and veneers were luted using two groups of cements Calibra veneer cement and Fusion Ultra D/C cement. After they were immersed in methylene blue dye solution for 24 h, the specimens were then sectioned buccolingual into three halves in a parallel vertical plane and measured dye penetration using a stereomicroscope (Zeiss). The data collected was recorded by the dye penetration index (0-4) and statistically analyzed using the IBM SPSS Statistics for Windows, Version 24 (Released 2016; IBM Corp., Armonk, New York, United States). Results It is evident that group 1 (Calibra veneer cement) showed the lowest mean score of 0.43 mm and group 2 (Fusion Ultra D/C) showed a highest mean score of 0.72 mm. Overall, when the two groups were compared for microleakage using SPSS, there was a significant difference among the groups. Conclusion It was determined that both the resin cements evaluated in this study showed microleakage to some level given the limits of the investigation and the findings. To evaluate the dye penetration of microleakage, the Calibra veneer resin cement showed a better marginal adaptability for veneer restoration. Further investigations with broader methodology and more clinical simulation are needed to evaluate other resin cements available for root surface indirect restorations to be analyzed for prospective clinical outcomes.
ABSTRACT
Pleomorphic adenoma (PA) is one of the most common benign lesions of the salivary glands, with a majority of them occurring in the parotid gland. PA has origin from the epithelial and mesenchymal elements and can arise from both major and minor salivary glands. Among minor salivary glands, the palate is the most commonly affected site, followed by lips, cheeks, gingiva, the floor of the mouth, and tongue. PA of the upper lip without intraoral mucosal involvement is a rare entity. In this article, we report a case of PA of the upper lip in a middle-aged female patient and its surgical management with a novel technique. During six months' postoperative review, the patient showed excellent wound healing with very minimal scar formation.
ABSTRACT
A Vitamin or mineral supplement is a kind of adjunct that aims to supplement the diet and it comprises a wide range of Vitamins, minerals, herbs, etc., that amplifies different nutrient levels. People intake such supplements for protection against health illnesses such as stress, cold, flu, osteoporosis, heart attacks, tooth decay, cancer, and neural tube defects in infants, etc. Anyhow, intake of large amounts without proper medical consideration can have severe negative consequences. This study aimed to assess the awareness on Vitamin and mineral supplements among College students. An online cross-sectional questionnaire was made using Google Forms and distributed among 100 College students. The data collected were analyzed using SPSS software. Descriptive analysis and Chi-square tests were done. Results showed that the majority of 63.43% of UG students and 21.64% of PG students believed that its consumption was beneficial and in general awareness was more among UG students. When asked about the Vitamin that should be avoided during pregnancy, a majority of 20.30% of UG students opted for Vitamin E and 7.52% of PG students opted for Vitamin A which shows that both were feasible options as they were fat-soluble vitamins capable of causing congenital defects. The most probable issue related with the use of dietary supplements is that the people who include them in their diet might see it as a substitute, in lieu of a supplement, thus, more people should be made aware of the proper consumption and side effects of Vitamin and mineral supplements.
