Immunofluorescence techniques were used to investigate perlapical lesions for the presence of components indicative of hypersensitivity reactlons medlated by humoral factors. In periapical granulomas, IgG, IgA, IgM and IgE cells represented 70, 14, 4 and 10 per cent, respectively, of the immunoglobulin-containing cells (ICC) observed. Intact and apparently degranulating mast cells were seen in ...

The study the effect of chronically infected sites on the immediate placement of implants, periapical lesions were induced in the third and fourth premolars of four dogs and the contralateral teeth were used as controls. Nine months after the induction of periapical lesions, experimental and control teeth were extracted, and 28 IMZ implants were immediately placed. After a healing period of 12 ...

Background: Endodontic flare up is a common complication of endodontic treatment that results from acute exacerbation pulpal and peri-radicular pathosis; leading to unscheduled emergency visits disturbing for both clinicians patients. Flare causes are multifactorial includes microbial, host, chemical mechanical factors. Objective: The aim this retrospective study was evaluate the incidence iden...

AIM The aim of this report is to present a case of Type III dens invaginatus in a maxillary lateral incisor with a periapical lesion and its successful treatment using a combination of surgical and non-surgical therapy. BACKGROUND The morphology of the root canal system is unique for individual teeth. A precise understanding of the morphology is very important for a successful root canal trea...

BACKGROUND AND AIM: The present study aimed to assess the nature and prevalence of incidental findings in cone beam computed tomography (CBCT) images of oral and maxillofacial patients. METHODS: In this cross-sectional study, 773 CBCT samples were retrieved from archives of a private oral and maxillofacial radiology center. Any findings that were not related to the reason of CBCT request was re...

OBJECTIVE The aim of this study was to evaluate whether the gap between the post restoration and the remaining root canal filling had an impact on the periapical health of endodontically treated teeth in a Turkish subpopulation. STUDY DESIGN Digital panoramic radiographs, evaluated for this cross-sectional study, were randomly selected from files of patients who attended to Yeditepe Universit...

BACKGROUND Though success rates of endodontic initial treatment have been improving over the years, persistence of periapical disease is far from being a rare condition. The most common therapeutical options for the re-treatment of teeth with periapical pathosis are non-surgical orthograde treatment and surgical treatment. Selection between alternative treatments should be based on assessment o...
