Introduction: Dens invaginatus is an extremely rare developmental disturbance that can occur in primary, permanent, or supernumerary teeth due to invagination of the enamel organ into dental papilla during tooth development. The clinical recognition radicular variant dens dente challenging as it mostly asymptomatic with a normal-appearing crown and incidentally discovered radiographs. Case pres...

Context: The accurate determination of working length (WL) has a major impact on the outcome root canal treatment. Aim: aim present clinical study was to compare accuracy using Cone Beam Computed Tomography (CBCT), Periapical radiograph and Electronic apex locator in teeth with periapical lesion. Settings Design: Randomised control trial. Materials Method: This conducted 30 patients an initial ...

The present study aimed to assess the prevalence of apical periodontitis (AP) in an urban Brazilian population according to gender, age group and tooth type. Data were collected from clinical files containing the medical and dental histories and periapical radiographs of 1,126 patients treated at the School of Dentistry at Universidade do Estado do Rio de Janeiro between March 2000 and December...

A 19-year-old female patient reported to the Department of Conservative Dentistry and Endodontics, with the chief complaint of food lodgment in her upper right and lower left back tooth. There was associated history of mild pain while bitting. Her medical and family history was noncontributory. Intra oral examination revealed a deep carious lesion with respect to the mandibular right second pre...

OBJECTIVES The aim was to determine the success rate of single visit root canal treatment (RCT) and thus encourage clinicians to offer this treatment option appropriately. MATERIALS AND METHODS This was a longitudinal clinical study involving all teeth of the secondary dentition except third molars in the upper and lower jaws. Teeth having irreversible pulpitis, pulp necrosis or periapical pe...

This study assessed the 4to 6-yr outcome of initial endodontic treatment during Phase 1 of the “Toronto Study” project. A total of 450 teeth were treated, alternating the “Schilder” technique and step-back with lateral condensation, and examined clinically and radiographically by an independent examiner. Apical periodontitis was recorded as absent (periapical index < 3) or present (periapical i...

The presence of Enterococcus faecalis in root canal teeth affected by primary and secondary periapical lesions was studied using polymerase chain reaction (PCR) assays. The association between presence of E. faecalis with clinical signs of apical lesions was assessed to evaluate a possible relationship between clinical findings. Microbial samples were obtained from healthy patients affected by ...

Objectives. To compare the ability of endodontists to determine the size of apical pathological lesions and select the most appropriate choice of treatment based on lesions' projected image characteristics using 2 D and 3 D images. Study Design. Twenty-four subjects were selected. Radiographic examination of symptomatic study teeth with an intraoral periapical radiograph revealed periapical les...

Calcium hydroxide [Ca(OH)2] has been widely used as short- or long-term intracanal antibacterial dressing material after endodontic treatment. In general when used in endodontics, Ca(OH)2 paste is composed of the powder, a vehicle, and a radiopacifier. To provide radiopacity, barium sulfate (BaSO4) powder is usually added to the paste. In this case report, BaSO4:Ca(OH)2 powders (ratio 1:8) and ...
