Comparison of the Effect of ProTaper and Gates-Glidden Drills On the Remaining Root Dentin Thickness at the Coronal Region of the Root
Background and Aim: The purpose of this study was to evaluate residual dentin thickness of the root and the area of the canal lumen in the coronal region of the mesiobuccal and mesiolingual canals of the lower first molars after canal preparation with the common method of using hand files and Gates Glidden drills or ProTaper rotary files, by Spiral Ct-Scan. Materials and Methods: In this exp...
متن کاملDentine microhardness after different methods for detection and removal of carious dentine tissue
UNLABELLED There are several methods for identifying carious dentinal tissue aiming to avoid removal of healthy dentinal tissue. OBJECTIVES The purpose of this study was to test different methods for the detection of carious dentinal tissue regarding the amount of carious tissue removed and the remaining dentin microhardness after caries removal. MATERIAL AND METHODS The dentin surfaces of ...
متن کامل[The development of ultrasonic diagnostic equipment for dental use].
When a dentist prepares a vital tooth, it is very important to know the distance between the prepared surface and the pulp chamber wall, and now we have developed ultrasonic diagnostic equipment which can indicate the nearness of these two boundaries by measuring the thickness of the remaining dentin. This equipment can be used to measure the thickness of the remaining dentin between the prepar...
متن کاملComparative evaluation of canal transportation, centering ability, and remaining dentin thickness between WaveOne and ProTaper rotary by using cone beam computed tomography: An in vitro study
AIMS To compare the canal transportation, centering ability, and remaining dentin thickness of WaveOne and ProTaper systems using cone beam computed tomography. SUBJECTS AND METHODS Forty extracted human single-rooted premolars were used in the present study. Preinstrumentation scanning of all teeth was taken; canal curvatures were calculated, and the samples were randomly divided into two gr...
متن کاملEffect of remaining dentin thickness on bond strength of various adhesive systems to dentin.
The aim of this study was to evaluate the effect of remaining dentin thickness (RDT) on resin composite bond strength to dentin surfaces when using various adhesive systems. One of three adhesives, Clearfil SE Bond, Single Bond or Clearfil Tri-S Bond, followed by Z100 resin composite were built up on flat dentin surfaces of human molars. The teeth were sectioned obtaining beams with crosssectio...
