چکیده
Within the limitations of this study, our results indicate that microtomography, with proposed semi-automatic algorithm, is a useful tools for three-dimensional quantitative evaluation of dental root canal fillings. In canals filled with thermoplastic gutta-percha and Tubli-Seal, voids at the interface between the filling and canal dentine deserve special attention due to of their periapical location, which might promote apical microleakage. Further studies might help to elucidate the clinical relevance of these results.

The quality of Thermafil obturations with different final apical tapers: a three-dimensional microcomputed tomographic comparative study.
AIM The aim of this study is to evaluate the influence of final canal taper on the sealing ability of Thermafil by using microcomputed tomography (micro-CT). MATERIALS AND METHODS Fifty-four single-rooted teeth were instrumented to apical size 40 taper 4, 6 and 8%. Teeth were divided into three groups. All teeth were filled with Thermafil (Dentsply,Tulsa Dental Products). Using micro-CT, root...

متن کاملRoot Canal Transportation in Canals Joining together: Assessed by Cone-Beam Computed Tomography
Introduction: Statement of the Problem: Cleaning and shaping are regarded as the most important aspects of root canal therapy and prerequisite for the success of endodontic treatment. Apical transportations can jeopardize the outcome of treatment due to the significant decrease in the sealing ability of root filling material. The purpose of this study was to evaluate transportation in type II c...
متن کاملApplication of the Curvature Scale Space Descriptor to the Problem of General Shape Analysis
In the paper the problem of General Shape Analysis (GSA) is investigated. It is similar to the recognition and retrieval of shapes. However, the analysed shape does not have to belong to any of the template classes. It is only similar to some of them. It may be said that the most general information about a shape is here concluded, namely how round, triangular, elliptical, etc. it is. This appr...
متن کاملComparison of transportation and centering ability using RECIPROC and iRace: A cone-beam computed tomography study
BACKGROUND AND AIM: Root canal treatment, especially in curved and constricted root canals, can be very difficult and time consuming. Several investigations have compared the reciprocating and full sequence motions in terms of shaping ability. The purpose of the present study was to compare the root canal transportation and centering ability of RECIPROC and iRace using cone-beam computed tomogr...
