To evaluate the microhardness of type II glass-ionomer cement (GIC) (restorative) and zirconia based glass –ionomer cement.

Twenty cylindrical samples measuring 5mm (diameter) and 5mm in length were prepared with type II glass-ionomer cement that is restorative (n=10) and zirconia based glass-ionomer-cement (n=10). Finishing and polishing was made with coarse grit to fine grit. Then samples were subjected to Vickers hardness tester by using digital micro hardness tester (Zwick/Roell) under a load of 300 grams for 15 seconds. The data obtained was subjected to statistical analysis and unpaired‘t’ test was used to compare the micro hardness between two groups.

Zirconia based glass-ionomer cements showed better micro hardness values as compared to that of type II glass-ionomer cement (restorative).

Better material with increased hardness like zirconia based GIC should be used in today's clinical practice. Further studies should be carried out to check other physical properties of zirconia based GIC.

Chlorhexidine mouth wash has been used for decades, however, it remains contraindicated in children and teenagers. On the other hand, the anti-microbial properties of plant derived compounds are well documented.

To compare, in vivo the efficacy and effectiveness of aqueous fruit extract of Terminalia chebula and Chlorhexidine oral rinse as an anti caries agent in children.

30 children in the age groups of 13 - 19 years were randomly selected for the study. The efficacy of the two agents (Terminalia Chebula and Chlorhexidine) as anti caries agents was assessed by evaluating the salivary pH and the salivary buffering capacity. The values obtained were subjected to statistical analysis.

A percentage improvement in buffering capacity was noted with Terminalia chebula when compared to Chlorhexidine mouthwash which indicated potential long term effects. The pH of both Terminalia chebula and Chlorhexidine did not show any significant difference.

Terminalia chebula can suitably be used as an anti-carious oral rinse and does not have any side effects such as erosion and staining.
