AIM To monitor ex vivo intra-canal irrigation with three endodontic needles (25, 27 and 30 gauge) and compare them in terms of irrigant flow rate, intra-barrel pressure, duration of irrigation and volume of irrigant delivered. METHODOLOGY A testing system was constructed to allow measurement of selected variables with pressure and displacement transducers during ex vivo intra-canal irrigation...

OBJECTIVE To compare the consistency rates of pre- and intra-operative radiological findings in patients with chronic suppurative otitis media (CSOM). METHODS In a cross-sectional study, 80 patients with CSOM underwent pre-operative CT scanning and we compared the results with intra-operative clinical findings during mastoidectomy from 2000-2004 in the Otology Department, Amiralmomenin Hospit...

dental trauma generally requires multidisciplinary planning and treatment for good prognosis. when immature teeth are traumatized to a degree where pulp necrosis ensues, the objective of root canal treatment should be apexogenesis and root maturation. apexification of the root is the conventional choice, which involves cleaning the canal and filling it with a temporary medication that stimulate...

this case report describes a 59-year-old woman with a giant basal cell carcinoma on the face neglected for 11 years. surgical resection of the lesion resulted in a 13 × 11 cm defect. issues regarding the adequately safe surgical margins and the management of the resultant defect through modern wound dressing technologies are discussed. keywords : giant basal cell carcinoma, modern dressing, gel...

microorganisms play a major role in initiation and perpetuation of pulpal and periapical diseases. therefore, elimination of the microorganisms present in the root canal system is the fundamental objective of endodontic treatment. the use of mechanical debridement, chemical irrigation or other antimicrobial protocols and intra-canal medicaments are critical to attain this goal. the aim of this ...

Tissue repair is an essential process that reestablishes tissue integrity and regular function. Nevertheless, different therapeutic factors and clinical conditions may interfere in this process of periapical healing. This review aims to discuss the important therapeutic factors associated with the clinical protocol used during root canal treatment and to highlight the systemic conditions associ...

This prospective randomized, double-blind factorial study aimed to compare the efficacy of three different intracanal medicaments with the placebo in controlling the postoperative pain after complete root canal preparation. The study was performed on 64 mandibular molars of 64 patients with diagnosis of pulp necrosis and acute apical periodontitis. After chemomechanical procedures using the ste...

This case report describes the non - surgical management of a large periapical lesion using Metapex as intracanal dressing and root canal therapy. Periapical lesions usually develop in non-vital teeth result chronic aggression by pathogenic microorganisms into which may appear radiolucent radiographs. Treatment such varies from non-surgical means depending on individual. In era minimally invasi...
