OBJECTIVES There is currently no standardised technique to measure the amount of coronal dentine remaining in a root-treated tooth after crown preparation. The aim of this study was to develop a method of measuring remaining coronal dentine in root-treated teeth and to propose an index for grading tooth restorability. METHODS The study recruited 20 patients who had completed molar endodontic ...

Rhizoctonia solani is an important soil-borne pathogen which has a broad host range and cause damping-off or rottenness of root and crown of cultivated plants. The combined use of different control methods in IPM programs is an effective strategy against pathogens and is useful especially in resistance management programs. In this study, EC50 and EC25 values of three conventional chemical fungi...
