Comparative Evaluation of Microleakage of Fiber-reinforced Glass Ionomer Cement and Conventional Glass Ionomer Cement Restorations Immersed in Three Different Beverages: In Vitro Study.

AIM: The aim of the study was to compare and evaluate the microleakage of fiber-reinforced glass ionomer cement (GIC) and conventional glass ionomer cement restorations immersed in three different beverages. MATERIALS AND METHODS: A total of 96 human exfoliating deciduous molars were selected which were cleaned and disinfected. Standardized Class V cavity preparations were done and buccal surface were restored with experimental fiber-reinforced glass ionomer cement (Exp-FRGIC), lingual surface were restored with Type II conventional GIC. They were divided into four groups according to the test beverage. The samples were subjected to various immersion regimes and evaluated for microleakage under stereomicroscope. RESULTS: Intragroup comparison for (Exp-FRGIC) showed significant microleakage when immersed in fresh fruit juice at high immersion whereas intragroup comparison in conventional GIC, showed highest microleakage with soft drink. Intergroup comparison of (Exp-FRGIC) in high immersion regime, showed more microleakage with specimen immersed in soft drink followed by fresh fruit juice. CONCLUSION: It can thus be concluded that the three beverages used in the study affected the microleakage of both restorative materials significantly. CLINICAL SIGNIFICANCE: Increasing usage of fruit juices in the pediatric diet has a definite impact on the progression of caries and it directly or indirectly affects the quality of restorations placed in the oral cavity.

Effect of Child Health Drinks on Color Stability of Various Aesthetic Restorative Materials - An In Vitro Study.

Introduction: In pediatric dentistry, the esthetically pleasing materials have tremendously changed the concept of restorative practice. Aim and Objectives: 1. The aim of the study is to evaluate the effect of child health drinks on color stability of various esthetic restorative materials via spectrophotometric analysis and to identify the esthetic restorative material that is color-stable against child health drinks. Materials and Methods: A total of 120 disk-shaped specimens with a diameter of 12 mm and a thickness of 2 mm were made from a composite (Dyract), giomer (Shofu), and composite (GC). Each group of 40 specimens of each material was divided into four sub-groups. Each sub-group was stored in different solutions, distilled water, Bournvita, Horlicks, and Pediasure, for 60 days. The color change measurement was done using a spectrophotometer both before and after staining. Result: One-way analysis of variance depicted that when the ΔE values of the restorative material were tested against each of the child health drink, there was a statistically significant difference between all child health drinks (P < 0.00001). When restorative materials were compared with the staining agent on 60 days duration, except Pediasure and Control, others (i.e. Horlicks and Bournvita) showed a statistically high significance (P < 0.05). Conclusion: Bournvita caused the highest color changes in 60 days time interval, followed by Horlicks and Pediasure. When the discoloration of several materials is studied, the highest level of discoloration was observed in the compomer, followed by the giomer, and the lowest level in the composite.

Comparative Evaluation of Antimicrobial Efficacy of Zinc Oxide Eugenol with Zinc Oxide Mixed with Three Herbal Products to be Used as Root Canal Filling Material: An In Vitro Study.

Introduction: Primary teeth with pulpal involvement and those having periapical issues should be retained until their normal exfoliation because their premature loss may lead to adverse aberrations in the future dentition. Root canals harbor different types of microorganisms and root canal infections generally are polymicrobial in nature. One of the most common and preferred root canal filling material which is commonly used for primary teeth is zinc oxide eugenol (ZOE) cement. Aims and objectives: To evaluate and compare the antimicrobial efficacy of ZOE with zinc oxide powder mixed with Morinda citrifolia extract, Aloe vera extract, and neem extract against Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. Materials and methods: The material used in the study were zinc oxide powder, eugenol liquid, M. citrifolia extract, A. vera extract, neem extract, petroleum jelly (Vaseline). The zinc oxide powder was mixed with minimum inhibitory concentration (MIC) percentage value of herbal extract. Result: Zinc oxide eugenol showed strong inhibitory effect against S. aureus and C. albicans. For P. aeruginosa, zinc oxide+M. citrifolia showed strong inhibitory. Petroleum jelly (Vaseline) was used as control agent which showed no inhibitory effect. Conclusion: The test root canal filling materials, i.e., ZOE, zinc oxide powder mixed with M. citrifolia extract, A. vera extract, and neem extract, respectively showed varied antimicrobial activity against the microorganisms tested, i.e., S. aureus, P. aeruginosa, and C. albicans.
