A comparative study of apical leakage of Endomethasone, Top Seal, and Roeko Seal sealer cements.

abstract：INTRODUCTION:Previous studies have suggested that masticatory forces are associated with cracked teeth, but it is not clear which specific poor oral masticatory habits may be more likely to cause cracks. The aim of this study was to quantitatively assess risk factors for cracked teeth among poor oral masticatory habits...
