Abstrakt: Background: To evaluate the effect of modifying conventional glass ionomer (CGIC) and resin-modified glass ionomer (RMGIC) with nano-hydroxyapatite (Nano-HA) on their clinical performance as restorations for class V cavities. Methods: The wet-chemical precipitation method was utilized to prepare the nano-hydroxyapatite particles. Nano-HA was then characterized using Scanning Electron Microscopy, Elemental Dispersive X-ray and thermal gravimetric analysis. Five wt% of the nano-hydroxyapatite (Nano-HA) was then incorporated into the powder portion of the CGIC and RMGIC. Sixty Class V cavities were prepared in thirty patients with at least two cervical caries lesions. Prepared cavities were restored using the tested materials. Modified United States Public Health Service (USPHS) criteria were used to evaluate the restorations at base line, after three, six and nine months. Results: Regarding the investigated modified USPHS criteria, the tested restorative materials showed no statistically significant difference throughout the study period. While color match, surface texture and marginal integrity criteria showed a statistically significant change in nano-HA-GIC. Surface texture and marginal integrity showed a significant change with CGIC. A significant change in surface texture was only found with nano-HA-RMGIC. Conclusions: The investigated restorative materials showed an equivalent clinical performance at the nine months follow-up. [ABSTRACT FROM AUTHOR]
