Abstract

Intra-radicular rehabilitation is a procedure in which the ischolar_main canals with very little remaining dentin thickness are strengthened by the use of such material that bonds and reinforces the ischolar_main structure. In this case report, intra radicular rehabilitation with the use of seventh generation bonding agent and flowable composite is described and discussed as a treatment approach for the restoration of a thin fragile ischolar_main. The procedure provides for an extended clinical application of the all-in-one bonding agent resulting in conservative, reliable treatment approach for the treatment of compromised ischolar_main canals due to variety of reasons.

Keywords

Abstract

Aim: The aim of this study was to evaluate the apical transportation, centering ability and cyclic fatigue resistance of Hero shaper, Twisted file, Hyflex file and RACE rotary file systems. Methods: Mesiobuccal ischolar_mains of eighty maxillary molars were divided into four groups and instrumented with Hero shaper, Twisted file, Hyflex file and RACE rotary file systems with a final apical size being 25/.04. Apical deviation was assessed by the radiographic platform method that enables obtaining superimposed images of the first and last instrument used in ischolar_main canal preparation in the same radiograph. Apical transportation was measured in millimeters with the aid of theAUTOCAD2008 software. Forty canals were sectioned at 7mm from the apex and stereomicroscopic Images were taken at 6x magnification before and after instrumentation for evaluation of centering ability. The cyclic fatigue testing was conducted with the instrument rotating freely at angles of curvature of 45 degree. Total 10 instruments were tested in each group. The instruments were rotated at 400 rpm using the X-smart motor (Dentsply, Maillefer) until fracture occurred. Results: There was no statistically significant difference between the four groups in apical transportation and centering ability whereas twisted files showed the maximum cyclic fatigue resistance. Conclusion: The different rotary file systems provided minimum canal transportation and the twisted file performed significantly better in terms of cyclic fatigue resistance.

Abstract

In case of failed ischolar_main canal treatment endodontic retreatment of the ischolar_main canal system is necessary. The aim of the present study was to compare the gutta-percha removal with Protaper retreatment files (Dentsply Maillefer, Ballaigues, Switzerland), K3 (SybronEndo) and Hero Shapers (MicroMega, Besancon, France). Method: Thirty freshly extracted human single ischolar_mained teeth were prepared with ProTaper rotary instruments up to file F3 andfilled with 30 # GP cones and AH plus sealer. The teeth were then stored for 1 week. The teeth were divide into 3 retreatment groups (n=10). The gutta-percha was removed using Protaper retreatment files, K3 and Hero Shapers. Teeth were then evaluated using radiographs. Results: Comparing the ratio between clean canals Protaper and K3 showed better debris removal as compared to Hero shaper. But no significance difference was found.

Abstract

External invasive ischolar_main resorption may occur as a consequence of trauma, orthodontic treatment, intracoronal bleaching and surgical procedures and may lead to the progressive and destructive loss of tooth structure. Depending on the extent of the resorptive process, different treatment regimens have been proposed. A 20-year-old female patient presented with tooth showing signs and symptoms of pain in 21 with extensive invasive resorption in middle third of ischolar_main canal. After ischolar_main canal treatment, The resorption area was chemomechanically debrided using ultrasonic tips and irrigant solution. MTA was used to fill the resorptive defect and the coronal access was temporarily sealed. Radiographs at 3 and 12 months showed adequate repair of the resorption and endodontic success. Clinically, the tooth was asymptomatic and found to be functioning well.

Abstract

From the past several years, there have been numerous studies that describe the morphology of teeth, including mandibular first molars. This tooth presents a high rate of intercanals and anastomosis, mainly in the apical 5 mm, which presents a clinical challenge in terms of cleaning and disinfection. A missed canal can lead to failure of endodontic therapy. Therefore every effort must be made to locate additional canals if any. This case report shows a variation in conventional anatomy in mandibular first molars.
