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 ...

HEIDI KOHLTFARBER, DDS: A Comparison of 2D versus 3D Radiography in the Diagnosis and Treatment Planning of Root Canal Treated Teeth with Periapical Lesions (Under the direction of Donald Tyndall) Objectives: The aims of the study were to assess diagnostic efficacy in lesion detection, evaluate the effect of cone beam CT on treatment planning and clinician confidence. Methods: Forty digital per...

Periapical lesions develop as sequelae to pulp disease. Periapical radiolucent areas are generally diagnosed either during routine dental radiographic examination or following acute toothache. Various methods can be used in the nonsurgical management of periapical lesions: the conservative root canal treatment, decompression technique, active nonsurgical decompression technique, aspiration-irri...

Long-term success of endodontic treatment is dependent on adequate and appropriate cleaning and shaping of the root canal along with proper and correct obturation of the entire prepared space. This article aims to report an exceptional non-surgical and orthograde endodontic treatment of maxillary right central incisor with an extensive radiolucent lesion in a 17-year-old male. Six and 20-month ...

The case reports describes non surgical healing in periradicular lesions.A conservative approach with 5.25% sodium hypochlorite was used for irrigation, and calcium hydroxide was used for the intra-canal dressing and 2% chlorohexidine as a final irrigant. Periapical healing was observed 1 month after obturation and continued in the 12-month recall. This report confirms that the large size of a ...

Quantitation of circulating immune complexes (CIC) was done in 45 patients with chronic periapical lesions. The levels were compared with those of age-matched healthy individuals. Both patients with chronic periapical granuloma and periapical cysts showed significantly higher levels of CIC than the controls. This observation indicates that the continuous presence of root canal antigens may caus...

With dawn of era of minimal intervention in dentistry, surgical management of periapical lesions become controversial. Non-surgical or conservative management of periapical lesions not only cause less trauma to the tissues, but also promote faster and less eventful healing. This paper presents successful management of a periapical lesion in a 14 year old male child with calcium hydroxide paste ...

Implant periapical lesions are infectious-inflammatory alterations surrounding an implant apex, and can be caused by a number of situations--including contamination at instrumentation, overheating of bone, and the prior existence of bone pathology. The diagnosis is based on the clinical manifestations and radiological findings, where a radiotransparency can be seen at periapical level. The lesi...

The aim of this study was to compare potential aspects of periapical lesion formation in hypertensive and normotensive conditions using hypertensive (BPH/2J) and wild-type control (BPN/3J) mice. The mandibular first molars of both strains had their dental pulp exposed. At day 21 the mice were euthanized and right mandibular molars were used to evaluate the size and phenotype of apical periodont...
