Etiology of different types of root resorption requires two phases: mechanical or chemical injury to the protective tissues and stimulation by infection or pressure. Injury can be similar in various types of root resorption. The selection of proper treatment is related to the stimulation factors. Intrapulpal infection is the stimulation factor in internal(More)
INTRODUCTION Numerous studies dealing with the outcome of surgical endodontic treatment have been published. However, study design, treatment protocols, follow-up periods, and inclusion and exclusion criteria are extremely variable. Thus, variable and confusing results have been reported. The aim of the present study was to assess the outcome of surgical(More)
OBJECTIVE To compare diagnosis of artificially induced external root resorption cavities using conventional intraoral film radiography (Kodak Insight), CCD sensor (Sopix wireless) and PSP sensor (Orex Digident). STUDY DESIGN Two mandibles were obtained from cadavers and teeth extracted from their alveolus. Artificial external root resorptions were(More)
OBJECTIVE We sought to evaluate the incidence and clinical outcome of an accidental finding of actinomycotic colonies in periapical lesions submitted for histologic examination. STUDY DESIGN The study included all periapical biopsy specimens submitted for histologic examination between 1997 and 2000. Sections of paraffin-embedded tissues, 5 microm, were(More)
INTRODUCTION Numerous studies on outcomes of surgical endodontic treatment have been published to date. However, study designs, treatment protocols, follow-up periods, and inclusion and exclusion criteria have been extremely heterogeneous. Thus, inconsistent and confounding results have been reported. The aim of this systematic review of the literature was(More)
The purpose of this retrospective study was to evaluate the 4-year outcome of endodontic microsurgery using two different magnification devices. One-hundred and two teeth in 65 patients were included according to specific selection criteria. Endodontic surgery was performed under surgical microscope as magnification device in 63 teeth in 36 patients, while(More)
INTRODUCTION The use of guided tissue regeneration (GTR) techniques has been proposed as an adjunct to endodontic surgery in order to promote bone healing. Studies assessing the added benefits of GTR for the outcome of endodontic surgery are significantly variable in their treatment protocols, follow-up periods, and inclusion criteria, thus generating(More)
OBJECTIVE To determine the prevalence,location, and distribution of sinus tracts in patients referred for endodontic consultation. METHOD AND MATERIALS This cohort study included 1,119 subjects referred for endodontic consultation, 108 of whom presented with sinus tracts. Following clinical and radiographic examination, the diameter of the rarifying(More)
INTRODUCTION This study aimed to evaluate the precision of electronic apex locators (EALs) in locating the apical constriction (AC) during a root canal treatment compared with a histologic evaluation of the AC as well as the effects of possible influencing factors by means of a systematic review of the literature and meta-analysis. METHODS A systematic(More)
The aim of this paper was to review the literature about the use of computerized tomography to evaluate the presence and characteristics of the second mesiobuccal canal in the maxillary first molar. An electronic search was performed. Frequencies of the presence of second mesiobuccal canal and root anatomy characteristics were extracted from the selected(More)
