This research was carried out in order to investigate the effects of temperature and relative humidity on the crack of restoration of glass ionomer cement. When the glass ionomer cement was restored to a human tooth cavity, the cracks were found on the surface of its restoration. These cracks on the surface of restoration disappeared by polishing, but in a few days, they appeared again on the polished surface. The effect of varnishing on the cracks of restoration was not recognized in this research. When the temperature and relative humidity of cement filled into polyvinylchloride (PVC) resin mould did not vary, the surface cracks of restoration did not appear. And they did not occur either with an increase in relative humidity or with constant relative humidity, regardless of temperature changes. But they occurred with a swift decrease of relative humidity.
