Obturated teeth were then divided into five groups according to the method of guttapercha removal in preparation for post receiving. Specimens were submerged in radioactive isotope solution of 137Cs chloride for 48 hours, rinsed under running water for three hours then sectioned longuitudinally and washed again and dried. Sectioned roots were placed with their canals downm on an ultraspeed Kodak x-ray films to quatify leakage. Results and conclusions: results showed that, the least leakage was found with hot pluggers while the maximum leakage was detected when rotary instruments were used for post space preparation.  ISSN : 0  Journal Name : Egyptian Dental Journal  Volume : 36  Issue Number : 3  Publishing Year : 1990 AH 1990 AD  Article Type : Article  Added Date : Tuesday, May 20, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email مديحة جمعة Gomaa, Madiha Researcher Doctorate mmahamad@kau.edu.sa Files File Name Type Description  Radioisotope Determination of Apical Seal Following Dowel Preparation.pdf pdf   Back To Researches Page
