D IAGNOSIS of periapical areas of rarefaction has always been a problem to the oral surgeon and general practitioner. A review of the literature reveals few studieF of apical roentgenolucent areas in the last 10 years. These investigations have concerned themselves mainly with teeth that have had extensive restorative and endodontic treatment. A study was undertaken to (I) evaluate, roentgenogr...

BACKGROUND Apical periodontitis includes periapical granulomas and radicular cysts, which are histologically distinguished by the absence and the presence of an epithelial lining, respectively. The main cause of apical periodontitis is the bacterial colonization of the root canal space. This research aimed at assessing whether and how periapical granulomas and radicular cysts differ in terms of...

BACKGROUND Efforts to select the appropriate number of implants in adolescent idiopathic scoliosis (AIS) instrumentation are hampered by a lack of biomechanical studies. The objective was to biomechanically evaluate screw density at different regions in the curve for AIS correction to test the hypothesis that alternative screw patterns do not compromise anticipated correction in AIS when using ...

INTRODUCTION Accurate and confident treatment planning is an essential part of endodontic practice. Periapical radiographs have been used to aid in the diagnosis of pathology and to help establish an appropriate treatment strategy. Recently, a new imaging modality, cone-beam volumetric tomographic (CBVT) imaging, has been shown to be a useful tool in a number of endodontic applications. The aim...

AIM To investigate the quality of root fillings and coronal restorations and their association with periapical status in an adult Spanish population. METHODOLOGY A total of 180 subjects, aged 37.1 +/- 15.7 years, who presented as new patients at the Faculty of Dentistry, Seville, Spain, were examined. All participants underwent a full-mouth radiographic survey incorporating 14 periapical radi...

AIM To present an additional case of intraosseous schwannoma involving the apical area in the mandibular alveolar bone mimicking an inflammatory periapical lesion. SUMMARY This article describes a case of schwannoma periapically located mimicking an inflammatory periapical lesion in the mandible of a 34-year-old female. Diagnostic and therapeutic problems can occur when this lesion is misinte...

The purpose of this case report is to describe the successful endodontic treatment and surgical management of a unesthetic geminated permanent maxillary lateral incisor tooth. Geminated maxillary incisor clinically revealed bifid crown with coronal groove and intraoral periapical radiograph showing radiolucent lesion with sclerotic border. orthograde root canal treatment was performed. surgery ...

A major paraclinical diagnostic method for the early and late follow-up of the healing process in chronic periapical lesions is the two-dimensional radiographic technique. About 32% of the periapical lesions are detected during a routine radiographic examination of neighboring teeth. Most of the periapical lesions are classified as granulomas, cysts and abscesses. The radiographic images of the...

The aim of this study was the radiographic evaluation of the apical and periapical region of dog teeth submitted to intracanal bacterial endotoxin (lipopolysaccharide, LPS), associated or not with calcium hydroxide. After removal of the pulp, 60 premolars were divided into four groups and were filled with bacterial endotoxin (group 1), bacterial endotoxin plus calcium hydroxide (group 2), salin...

The purpose of this study was to evaluate the effects of aminoguanidine (AG) as a selective inhibitor of inducible nitric oxide synthase (iNOS) on the degree of inflammatory response in periapical lesions in the canine teeth of cats. Root canals from 52 cat canine teeth were exposed to the oral cavity and sealed after 7 days. One day before pulp exposure, cats were administered either AG (exper...
