The objective of this study was to determine the efficacy of chemical-mechanical procedures of two endodontic protocols for septic content reduction of root canals from primary teeth with pulp necrosis and periradicular lesion. Twenty-four primary root canals with pulp necrosis and periradicular lesion were divided into two treatment groups (n=12): multiple-visit and single-visit protocols. Sam...

BACKGROUND Advances in the art and science of endodontics have facilitated better understanding of disease processes and have led to development of treatment modalities aimed to restore health to the pulp and periradicular tissues. This article presents a summary of both basic and clinical breakthroughs in endodontics. RESULTS The author indicates that, on the basis of the reviewed literature...

The number of appointments necessary to treat infected root canals is one of the most controversial issues in endodontics. This study evaluated, in dogs, the response of the periradicular tissues to the endodontic treatment of infected root canals performed in a single visit or in two visits, using different interappointment dressings. Periradicular lesions were induced by inoculating Enterococ...

One hundred seventeen patients with posterior teeth requiring endodontic treatment were studied. Specific clinical findings were recorded, including pulp, vitality, preoperative pain, sensitivity to percussion, and the presence of a periradicular radiolucency. Excluded from the study were teeth with restorations to be maintained, greater than class I mobility, pocket depths > 5 mm, endodontic r...

Periradicular surgical procedures were performed on rhesus monkeys and the wound healing responses of the tissues of the periodontium were evaluated by light microscopy. This article, Part I of the investigation, reports the mucoperiosteal tissue wound healing responses to incisional wounds of the triangular and submarginal rectangular flap designs. Little difference was found in the temporal a...

Objectives: 1.To clinically evaluate the healing process following periapical surgery with Chitra granules 2.To radiographically evaluate healing, following periapical surgery with Chitra granules. 3.To compare the bone healing in the study group, clinically and radiographically following the modalities of treatment, with that of the control group (without graft). Materials: 1.Chitra hydroxyapa...

Biopsy reports from 150 periradicular tissue specimens obtained from teeth refractory to nonsurgical endodontic therapy were reviewed. The specimens were submitted by postdoctoral dental students in the Department of Endodontics, and the biopsy reports were prepared by oral pathologists at the University of Texas Health Science Center at San Antonio. The study found that 59.3% of the periradicu...

Microorganisms play an unequivocal role in infecting root canal system. Endodontic infections are different from the other oral infections in the fact that they occur in an environment which is closed to begin with since the root canal system is an enclosed one, surrounded by hard tissues all around [1,2]. Most of the diseases of dental pulp and periradicular tissues are associated with microor...
