Endodontic management of taurodontic teeth

Taurodontism is a morpho-anatomical change in the shape of the tooth in which the body of the tooth is enlarged and the roots are reduced in size. Although taurodontism is a dental rarity, this unusual radicular form should merit circumspect considerations in planning and treatment. Endodontic management in taurodont teeth has been described as complex and difficult. The present paper describes the successful completion of endodontic treatment in three taurodontic teeth with appropriate use of instruments and techniques and also emphasizes the need for post endodontic rehabilitation.

Endodontic treatment of the young permanent teeth

Pulp treatment in the young permanent teeth represents significant problem in peadiatric dentistry. The aim of this paper was to present the course of endodontic treatment of a young permanent tooth and success after 26 years. Upper right central incisor remained functional following thorough endodontic therapy, temporary root canal filling with calciumhydroxide and final root obturation. After 26 years from the beginning and completion of endodontic treatment, the tooth is still in normal funciton.

Fracture strength and survival rate of endodontically treated maxillary incisors with approximal cavities after restoration with different post and core systems: an in-vitro study

Objectives: This study compared the fracture strength and survival rate of endodontically treated crowned maxillary incisors with approximal class III cavities and different core build-ups. Methods: Sixty-four caries free human maxillary central incisors were selected for standardized size and quality, endodontically treated and prepared with approximal cavities 3 mm in diameter. Group 1 was restored with titanium posts, group 2 received zirconia posts, in group 3 the root canal was partially filled with a hybrid composite. In the control group, only the access opening was restored. All teeth were prepared for and restored with full cast metal alloy crowns and subsequently exposed to 1.2 million cycles in a computer-controlled chewing simulator with simultaneous thermocycling. In addition, the samples were loaded until fracture in a static testing device. Results: One specimen with composite reinforced root canal did not survive the dynamic load test. The following median fracture strengths in Newtons for the different groups were: titanium post 1038, zirconia 1057, composite resin 750, control (no post) 1171. The fracture load in group 3 (composite resin) was significantly lower ( P<0.05) than in the other groups. Conclusions: The reconstruction of endodontically treated single rooted teeth with approximal cavities can be successfully performed by closure of the endodontic and additional cavities with composite. Cementation of endodontic posts offers comparable but no advantageous fracture resistance. Enlargement of the root canal space after completion of endodontic treatment should be avoided and cannot be compensated for by injection of composite resin. Less catastrophic failures were observed without post reconstruction.

Endodontic Considerations in Restoration of Partial Overdenture Abutments

Overdenture abutment teeth often require endodontic treatment. Various factors, such as status of the pulp, periodontal state of the tooth, and the sequence of overdenture treatment, influence endodontic management of the patient. After completion of endodontic treatment, the coronal part of the root filling is removed, leaving an adequate amount of the root filling in the apical part of the root canal undisturbed. The abutment tooth is then permanently restored with a filling material, or is prepared for a cast restoration.

Electric pulp testing as an aid in endodontic diagnosis

History and examination. A 21year-old whiteowoman was referred for treatment by her dentist. She had consulted the dentist a week earlier because of pain and swelling in the maxillary right anterior region. The dentist administered local anesthetic, and opened the pulp chamber of the maxillary right lateral incisor. The tooth was left open, and the patient was given an appointment to return in eight days for completion of endodontic treatment. Three days later, her condition had not improved; therefore, the dentist administered local anesthetic, opened the pulp chamber of the maxillary left central incisor, and left it open. The patient returned two days later ~and reported that the pain and swelling had not changed. The dentist then referred the patient, and she was seen immediately. The gingiva over her maxillary right lateral incisor was swollen (Fig 1). There were access openings into the pulp chambers of the maxillary right lateral and left central incisors (Fig 2). The maxillary right central incisor was tender to light percussion and was slightly mobile. A radiograph (Fig 2) was taken, which showed an apical lesion apparently associated with the apexes of the maxillary right central and lateral incisors. On examination with the electric pulp tester, however, a normal response was obtained from all maxillary teeth from canine to canine, except for the maxillary right central incisor, which gave no response, despite the fact that the root canals of two of these teeth had been opened five and three days earlier, respectively. The patient said that no electric pulp testing had been done during the three visits before her referra l .

Managing the abscessed tooth: instrument and close?

Two hundred seventy-one patients whose abscessed teeth were left open for drainage were evaluated for a minimum period of 18 months after completion of endodontic treatment. The abscessed teeth were instrumented and closed at the same appointment, followed by a dressing change within 24 hours. It was found that this method of treatment caused a minimal number of exacerbations and resulted in a high rate of success. The study also revealed that teeth with periapical radiolucent areas are more prone to have exacerbations, require a greater amount of surgical intervention, and have a higher rate of failure than teeth without such areas.
