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 The incidence of post-operative pain was compared following single-visit canal treatment in single- and multi-rooted teeth, with and without periapical radiolucency. The article also reviews the issues of postoperative pain and healing, following single-visit and multi-visit endodontic therapy. Single-visit endodontic therapy (SVE) was performed in 50 single-rooted teeth and 60 multi...

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 ...

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...

Periapical lesions are among the most frequent periodontal pathologies in human teeth, generally called apical periodontitis. Apical periodontitis is a continuation of the endodontic space infection and it is manifested as a response of the host defense against the microbial action. It may determine local inflammation, hard tissue resorption, destruction of other periapical tissues. The prelimi...

AIM To study the prevalence of AP in patients with and without type 2 diabetes mellitus. METHODOLOGY In a retrospective cohort study, the records of 38 subjects with diabetes and 32 control subjects were examined. All participants underwent a full-mouth radiographic survey incorporating 14 periapical radiographs. The periapical region of all teeth, excluding third molars, was examined. Periap...
