The aim of this work is to enhance the mechanical properties of the glass ionomer cement GIC (dental materials) by adding Zirconium Oxide ZrO2 in both micro and nano particles. GIC were mixed with (3, 5 and 7) wt% of both ZrO2 micro and nanoparticles separately. Compressive strength (CS), biaxial flexural strength (BFS), Vickers Microhardness (VH) and wear rate losses (WR) were investigated. The maximum compression strength was 122.31 MPa with 5 wt. % ZrO2 micro particle, while 3wt% nanoparticles give highest Microhardness and biaxial flexural strength of 88.8 VHN and 35.79 MPa respectively. The minimum wear rate losses were 3.776µg/m with 7 wt. % ZrO2 nanoparticle. GIC-containing ZrO2 micro and nanoparticles is a promising restorative material with improved mechanical properties expect wear rate losses.

BACKGROUND Marginal integrity of glass ionomer as a restorative material is an important factor for the longevity of the restoration. Class V and cervical abrasions are the most critical and challenging lesions for restorations. The choice of material for restoring class V and cervical abrasions is glass ionomer cement (GIC). Sensitivity to moisture contact during the early setting stages is the drawback of GIC. To overcome the drawback, modifications of glass ionomer cement were made by the addition of chitosan. Chitosan (CH) is a natural linear polysaccharide obtained partially and fully by deacetylated chitin compounds, which are found in crab and shrimp shells, with properties like nontoxicity, biodegradability, bioadhesive, biocompatibility, and biorenewabilty which has led to its use in various fields. Thus, this study intended to evaluate the microleakage of conventional glass ionomer cement and chitosan modified glass ionomer cement using a spectrophotometer. METHODS 60 teeth extracted for orthodontic propose were selected for the study and randomly divided into two groups, class V cavities were prepared on the buccal surface and samples were restored with conventional glass ionomer cement and chitosan modified glass ionomer cement respectively, teeth were immersed in 0.5 % methylene blue for 24 hours and assessed using a spectrophotometer. RESULTS The data were analysed using the Unpaired T - test, and with statistical package for social sciences (SPSS) for Windows, version 25.0 (IBM Corp., Armonk, N.Y., USA). The confidence interval was set at 95 % and values of P < 0.05 were interpreted as statistically significant. CONCLUSIONS The study concluded that the addition of chitosan improves the mechanical properties of conventional glass ionomer cement, and a spectrophotometer can be used as a better evaluation tool in assessing microleakage.
