A nonsurgical technique for the removal of overextended gutta-percha.
AIM The present report describes and discusses a nonsurgical technique for the removal of overextended gutta-percha. BACKGROUND Mechanical irritation results from overextension and the overextended material used during root canal obturation could produce an inflammatory reaction with an area of rarefaction in the periapical tissues. The healing process is not affected by the presence of filli...
متن کاملThe efficacy of gutta-percha removal using ProFiles.
AIM The purpose of this study was to compare the efficacy in vitro of gutta-percha removal from obturated root canals using ProFiles. METHODOLOGY Forty-eight human root canals with curvatures ranging between 25 and 45 degrees were instrumented by a standardized method to an apical ISO size 30 and 0.04 taper. They were obturated with vertically condensed gutta-percha. Retreatment was performed...
متن کاملDeposition of calcified tissue around an overextended gutta-percha cone: case report.
CASE REPORT Root canal treatment was performed in a mandibular right second premolar with a periapical lesion and apical resorption. The root canal was prepared with K-files using the step-back technique and 3% NaOCl as an irrigant; during obturation gross overfilling of gutta-percha occurred. The tooth was permanently restored with a post and core along with a crown. Although healing of the pe...
متن کاملNonsurgical management of a large periapical lesion using aspiration in combination with a triple antibiotic paste and calcium hydroxide
Persistent microorganisms in the root canal are known to cause endodontic treatments failure. Overextended gutta-percha can also act as a periradicular tissue irritant, leading to large periapical lesions. Retrieval of overextended gutta-percha with a nonsurgical approach can prove to be a challenge. This case describes the nonsurgical management of a large periapical lesion associated with ove...
متن کاملThe thermomechanical properties of gutta-percha. I. The compressibility of gutta-percha.
Sample wafers of compounded dental gutta-percha and uncompounded dental-grade gutta-percha were compression tested to 20,000 pounds in uniaxial and triaxial systerns. Unrestrained flow in the uniaxial series prevented development of stress levels sufficient to produce molecular compression. Negligible molecular compression did occur in the triaxial series but only above a stress level of approx...
