OBJECTIVE The purpose of this study was to evaluate the pulp healing process and the dentin-cementum complex in 51 endodontically treated human teeth after long observation periods and to correlate histologic observations with conventional periapical radiographic findings. STUDY DESIGN Specimens were obtained from the extraction of 77 treated teeth, which were deemed to be unrestorable, with ...

OBJECTIVES The purpose of the study was to evaluate human dental pulp response to pulpotomy with calcium hydroxide (CH), mineral trioxide aggregate (MTA), and calcium enriched mixture (CEM) cement. MATERIALS AND METHODS A total of nine erupted third molars were randomly assigned to each pulpotomy group. The same clinician performed full pulpotomies and coronal restorations. The patients were ...

Knowledge of the size, morphology, and variation of the root canals of a primary tooth is useful in visualizing the pulp cavity during treatment. The roots of the primary teeth are formed completely approximately 16 to 20 months following eruption.1 In approximately three years the roots begin to resorb at the apex or on a lateral surface near the apex.2 The form and shape of the root canals ro...

Tissue engineering is a growing field. In the near future, it will probably be possible to generate a complete vital tooth from a single stem cell. Pulp revascularization is dependent on the ability of residual pulp and apical and periodontal stem cells to differentiate. These cells have the ability to generate a highly vascularized and a conjunctive rich living tissue. This one is able to colo...

Apical periodontitis is an inflammatory lesion in the periodontal tissues that is caused mostly by bacterial elements derived from the infected root canal system of teeth (Core concept 7.1). In non-treated teeth apical periodontitis represents a defensive response to a primary infection in a necrotic pulp. Apical periodontitis may also develop due to a secondary infection subsequent to endodont...

PULPECTOMY – Treatment Considerations Anesthesia It is essential to eliminate any sensation from the tooth being treated prior to endodontic therapy. While it is true that some necrotic teeth can be treated without anesthesia, placement of rubber dam clamps and instrumentation beyond the apex (patency filing) normally make the use of local anesthetic desirable. This is typically achieved throug...

Endodontic management of the teeth with immature apices and necrotic pulps has always been challenging. Therefore fabrication of an artificial hard tissue barrier with a biomaterial has indicated as an alternative to more traditional apexification procedure. Successful endodontic treatment needs to prevent leakage of intracanal irritants into the peri radicular tissues. On the other hand, achie...

Root-end resected teeth with persistent apical periodontitis are usually retreated surgically or a combination of non-surgical and surgical retreatment is employed. However, patients are sometimes unwilling to be subjected to a second surgical procedure. The apical barrier technique that is used for apical closure of immature teeth with necrotic pulps may be an alternative to non-surgically ret...

OBJECTIVE The purpose of this study was to evaluate the efficacy of erbium lasers for retrograde endodontic treatment, in terms of clinical outcome and therapeutic success. BACKGROUND DATA Apicoectomy with retrograde filling is a well-established surgical procedure to treat teeth affected by persistent periapical lesions. The apical root end is generally removed with burs, and the adjacent pe...

INTRODUCTION Pulp sensitivity testing, even with its limitations and shortcomings, has been and still remains a very helpful aid in endodontic diagnosis. Pulp sensitivity tests extrapolate pulpal health from the sensory response. The aim of the present study was to identify the sensitivity, specificity, positive and negative predictive values (NPVs) of thermal and electrical tests of pulp sensi...
