The aim of this study is to analyze and characterize the antimicrobial effect of cerium oxide nanoparticles (NP) synthesized using neem and ginger. Finely grounded neem and ginger powder were taken and mixed with distilled water. This mixture was then heated and filtered. Ammonium cerium nitrate dissolved in distilled water. Both the mixtures were mixed and stirred magnetically. A double-beam ultraviolet-visible spectrophotometer was used to monitor color changes. The extract was centrifuged at 8000 rpm for 15 min. The final pellet was powdered using a hot air oven at 70°C for 24 h. Visualization was done by transmission electron microscopy and spherical morphology was noted, with an average diameter of 5 nm, in aggregated form. The sample containing 100 mg of cerium oxide shows the most significant effect on the zone of inhibition of 11 mm of Staphylococcus aureus. The results obtained in the current study confirmed that CeO-NP possessed antioxidant and cytotoxic properties.

In countries with a high amount of geriatric patients, it is mandatory for a dental clinician to have working knowledge on complete denture (CD) procedures. The aim of this study was to troubleshoot the errors in denture fabrication by assessing the difficulties in clinical procedures. A questionnaire was distributed among dental undergraduates across the country in the present study. A total of 26 questions were included in the study. An online sharing medium was used for distribution and a total of 140 responses were received. SPSS for windows, version 20 was used for data tabulation. Descriptive statistics and Chi-square test were done. The results of this study revealed that jaw relation was the most difficult procedure followed by border molding. Multiple problems arise from the practitioner's end due to the lack of knowledge. One of the causes for these problems could be inability to learn the principles and procedures during the undergraduate program. This must be addressed at the base level so that better care can be given to patients.

The present invention relates to dental compositions that include a phosphorescent material, more particularly, adding phosphorescent material to waxes that used in dentistry. The aim of the study is to develop a wax that has innate phosphorescent properties. Three groups of samples were taken in which the phosphorescent material was added. Three groups were later compared for their phosphorescent property in the material. All the samples in the initial molten state were poured into a mold made of silicone impression material and allowed to set. The material was placed in a dark room, and visual examination was done to compare the materials. From the samples obtained, paraffin wax showed more phosphorescent property than beeswax. The least phosphorescent property was seen in marginal wax. It can be concluded from this study that paraffin wax showed the most phosphorescent property.
