Root Canal System

We aimed to analyze the morpho-geometric changes of the root canal system created by two rotary systems (TF Adaptive and BioRace) using micro-CT technology. Two concepts of rotary file system kinematics, continuous rotation and adaptive kinematics, were used in root canal preparation. Twenty mandibular molars (n = 20) were selected with the following criteria: the teeth have mesial roots with a single and continuous isthmus connecting the mesiobuccal and mesiolingual canals (Vertucci’s Type I configuration) and distal roots with independent canals. Teeth were scanned at a resolution of 14 μm. Canals were divided equally into two groups and then enlarged sequentially using the BioRace system and TF Adaptive system according to manufacturer protocol. Co-registered images, before and after preparation, were evaluated for morphometric measurements of canal surface area, volume, structure model index, thickness, straightening, and un-instrumented surface area. Before and after preparation, data were statistically analyzed using a paired sample t-test. After preparation, data were analyzed using an unpaired sample test. The preparation by both systems significantly changed canal surface area, volume, structure model index, and thickness in both systems. There were no significant differences between instrument types with respect to these parameters (p > 0.05). TF Adaptive was associated with less straightening (8% compared with 17% for BioRace in the mesial canal, p > 0.05). Both instrumentation systems produced canal preparations with adequate geometrical changes. BioRace straightened the mesial canals more than TF Adaptive.

The purpose of this study was to evaluate biocompatibility of a new injectable root canal sealer. The cytotoxicity of zinc oxide-eugenol cements, CCQ and the new injectable root canal sealer were assessed by the MTT assays. These materials were filled into the root canals of the dog. One month later, the dog was sacrificed and the X-ray photos were taken. The histological response was observed through the microscope. The results show the new injectable root canal sealer showed better biocompatibility than the other two materials.

Aim. To compare digital images of conventional radiographs with the original radiographs for perceived clarity of periapical lesions and the quality of root canal treatment. Materials and Methods. One hundred and four intraoral periapical radiographs of patients with endodontically treated teeth were randomly selected. The radiographs were digitized using an MD300 USB X-ray Reader. The digital images were transferred to an HP laptop. Three evaluators compared each conventional radiograph with the matching digital image. The images were ranked for clarity and assessed for diagnostic quality; data were analyzed using the Reliability Calculation “ReCal.” Results. Both the digital images and conventional films had comparable clarity and diagnostic quality. Results indicated a moderate agreement between the evaluators. Conclusions. Conventional radiographs digitized using an MD300 USB X-ray Reader have similar clarity and diagnostic quality in comparison to the original radiographs.

Abstract A progressive bacteria invasion on tooth tissues leads to pulp inflammation, microabscesses of the pulp, destruction and in consequence inflammation of periapical tissues. Therefore the aim of endodontic treatment is three dimensional debridement of a root canal from the vent in pulp chamber to the physiological narrowing. Therefore the aim of the study is analysis of root canal configuration, number of canals, presence of lateral canals and canal delta with the group of first permanent molars. At the same time the accuracy of the radiological examination (x-ray images) is estimated due to comprehension of X-ray images performed before teeth preparation with root canal system and after observation of transversal cuts by means of light microscopy and microtomography. This establishment is presented through the differences in conventional radiological image and clinical assessment.
