Materials and methods: Three types of endosonic enlarging files were used in this study, namely, the K-type and the Diamond coated files. Three brands and three sizes of each type were investigated. One source of vibration ‘’ultrasonic unit’’ was used with all the files studied. The study was done by means of a travelling microscope and a stereomicroscope. It resulted in 30 detailed vibration patterns ( in air and in water). Results and conclusions: Vibration pattern study is useful and convenient method for determining the potential clinical efficiency of an endosonic instrument. Files of the same design type and the same size can be ranked according to their vibration patterns. Vibration in water decreases the displacement amplitude in all sizes examined.  ISSN : 0  Journal Name : Egyptian Dental Journal  Volume : 6  Issue Number : 2  Publishing Year : 1991 AH 1991 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 Investigator Doctorate mmahamad@kau.edu.sa نجيب أبو العنين Abul Elinein, Nagueb Researcher Doctorate   إيناس سامي Samy, Inas Researcher Doctorate   محمود فرج Farag, Mahmoud Researcher Doctorate   Files File Name Type Description  Vibration Pattern of Different Endosonic Instruments.pdf pdf   Back To Researches Page
