This study elucidates the role of interleukin-1 (IL-1) in developing periradicular lesions in immunocompetent and immunocompromised (human immunodeficiency virus/acquired immune deficiency syndrome) hosts. Eight cats were immunosuppressed with steroids before infection with feline immunodeficiency virus (FIV). Eight uninoculated cats served as controls. Periradicular lesions were induced around...

AIM To examine the clinical and radiographic appearance of teeth that suffered premature interruption of root development and were treated by an mineral trioxide aggregate (MTA) apical plug technique. SUMMARY Eleven teeth with immature root apices in 11 patients were treated nonsurgically by the manual application of MTA in the apical portion of the root canal under microscopic vision. Follow...

Objective: A review was made of the current literature on hemostatic agents used in apical surgery in order to determine their effectiveness and adverse effects. Material and methods: The main search terms used were: endodontic surgery, apicoectomy, apical surgery, periradicular surgery, hemostasis, hemostatic agents, and bleeding control. The authors searched the Medline database for articles ...

dens invaginatus is a rare developmental anomaly of teeth with complex root canal system morphology. the present case describes a peg shape maxillary lateral incisor with dens invaginatus (oehlers type ii), necrotic pulp, and an associated large periradicular lesion. nonsurgical endodontic treatment was performed with the aim of removing the blind sac with diamond bur under the use of operating...

The purpose of this study was to evaluate in vivo the response of the periradicular tissues after endodontic treatment and root filling with Epiphany/Resilon (Penntron Clinical Technologies, LLC, Wallingford, CT) or gutta percha and new Sealapex (SybronEndo, Glendora, CA) in dogs' teeth with or without coronal restoration. Teeth without coronal restorations were used to assess the influence of ...

The purpose of a root-end filling is to establish a seal between the root canal space and the periradicular tissues. As root-end filling materials come into contact with periradicular tissues, knowledge of the tissue response is crucial. Almost every available dental restorative material has been suggested as the root-end material of choice at a certain point in the past. This literature review...

Excisional wounds were made in the maxillas and mandibles of rhesus monkeys, and the osseous wound-healing responses at postsurgical intervals ranging from 1 to 28 days were evaluated by light microscopy. The excisional defects were initially filled with a coagulum which was subsequently replaced by granulation tissue emanating from the endosteal tissues. Cortical and trabecular bone forming th...

AIM To evaluate the haemostatic efficacy and the histologic tissue responses after the application of different haemostatic agents used in periradicular surgery. METHODOLOGY The study was conducted in the calvarium of six rabbits. Standardized bone defects (diameter 4 mm) were trephined, and different haemostatic agents were applied and compared with control defects: bone wax (left for 10 min...

Introduction: The attempt to contain microbial proliferation does not prove be viable or solvable through coronary access, periapical parendodontic surgery is indicated as a therapeutic complement. Periapical intended provide healing periradicular tissues, generating rehabilitation of dental function, which in cases such retro filling and tissue repair. Objective: It was carry out systematic re...
