This study analyzed the antimicrobial effect of photodynamic therapy (PDT) in association with endodontic treatment. Twenty patients were selected. Microbiological samples were taken after accessing the canal, endodontic therapy, and PDT. At the end of the first session, the root canal was filled with Ca(OH)(2), and after 1 week, a second session of the therapies was performed. Endodontic thera...

Photodynamic therapy (PDT) is presented as a promising antimicrobial therapy that can eliminate microorganisms present in endodontic infections. This treatment is based on the use of a nontoxic photosensitizing agent followed by irradiation of a resonant light source being capable of generating highly reactive species that are harmful to microorganisms. The purpose of this paper is to review th...

AIM To report a case of conservative nonsurgical management of periapical lesions. BACKGROUND Small periapical lesions of endodontic origin usually heal by conventional endodontic therapy alone. Larger periapical lesions presumed to be cystic may require additional treatment protocols to aid in regression. Conservative nonsurgical management of such lesions eliminates the possible complicatio...

Successful root canal therapy requires a thorough knowledge of root anatomy and root canal morphology which may be quiet variable. The significance of internal root canal morphology has been emphasized by studies demonstrating that variations in canal morphology may affect the endodontic outcome. Consequently, in treating each tooth the clinician must assume that complex anatomy occurs often en...

BACKGROUND Aim of this study is to compare the clinical and radiographic success of non-surgical endodontic therapy in patients receiving intravenous zolendronate less than 1 year and more than 1 year. METHODS The clinical and radiographic follow-up data of 24 patients who were receiving IV zolendronate with 37 teeth were retrieved from the archives to evaluate clinical and radiographic heali...

There are numerous examples reported in the literature that cite and document many disabling complications to the alveolar bone, neurovascular anatomy and maxillary sinus following overextension of root canal filling materials. Neural complications as a consequences of endodontic obturation as well as other server outcomes to overfill are a serious problem. These injuries require a thoughful st...

UNLABELLED The radicular groove is a developmental anomaly that predisposes the tooth to periodontal break-down. Sometimes the situation becomes more complicated by pulp necrosis and development of a combined endodontic-periodontal lesion which is a diagnostic and treatment challenge for the clinician. This report presents the successful management of an endodontic-periodontal lesion in a maxil...

Recent advances in endodontic instrumentation have simplified the treatment process and improved long-term success. Ten years ago the vast majority of endodontic instrumentation was being performed with hand files and reamers. Today, most practitioners providing endodontic therapy are utilizing rotary instrumentation.

The aim of this report is to describe the treatment of two mandibular incisors of the same patient with apical periodontitis following dental trauma. Tooth 31 was treated by single-visit endodontic therapy while tooth 41 was treated by multiple-visit endodontic therapy. A 16-month postoperative radiograph was taken and showed repair.

BACKGROUND AND OBJECTIVE To compare the effectiveness of antimicrobial photodynamic therapy (PDT), standard endodontic treatment and the combined treatment to eliminate bacterial biofilms present in infected root canals. STUDY DESIGN/MATERIALS AND METHODS Ten single-rooted freshly extracted human teeth were inoculated with stable bioluminescent Gram-negative bacteria, Proteus mirabilis and Ps...
