AIM The aim of this study was to assess the apical sealing ability of Resilon obturation material. METHODS AND MATERIALS Forty-two single rooted extracted human teeth were selected and randomly divided into three groups. They were obturated using lateral condensation with gutta-percha and AH 26/AH plus and Resilon; also, 12 root canals were used as control groups. The apical leakage was measu...

Background: Chronic apical periodontitis is potential infection with poor symptoms that are easily overlooked. Disease progession can lead to cellulitis, osteomyelitis, sinusitis, endocarditis, nephritis, arthritis, persistent fever and sepsis. In recent times, thanks advances in endodontic improving instruments, root canal antiseptics, techniques for shaping, obturation canals, treatment has a...

AIM To ascertain the adoption of new endodontic technology in general dental practice in India in 2011. METHODOLOGY A postal questionnaire survey comprising 26 questions was sent to 700 general dental practitioners. The questions covered professional activity, root canal preparation and instrumentation, choice of irrigants and intracanal medicaments, choice of obturation techniques and other ...

Sudden occlusion of the left anterior descending branch approximately 2 cm. below the ostium of the left circumflex coronary artery in the dog's heart produces a mortality rate of approximately 50 per cent. In dogs weighing approximately 15 kilos surviving more than 24 hours (average 1 week), an infarction is produced which almost invariably measures 5 x 5 cm. on surface. Following coronary sin...

introduction: the purpose of this study was to compare first accessory gutta-percha penetration after the use of nickel-titanium (ni-ti) or stainless-steel spreaders in curved resin blocks. materials and methods: forty resin blocks with 30º and 45º curvatures (20 blocks for each) were prepared and #30 master cones were placed in canals. in part one, under 20 newton pressure, ni-ti or stainless-...

background and aims. the single-cone technique has gained some popularity in some european countries. the aim of the present study was to compare the push-out bond strength of gutta-percha to root canal dentin with the single-cone and cold lateral compaction canal obturation techniques. materials and methods. the root canals of 58 human mandibular premolars were prepared using modified crown-do...

background: the incidence of dentinal defects may infl uence the outcome of root canal treatment. the aims of this study were to evaluate and compare the incidence of dentinal defects following root canal obturation with two different techniques. materials and methods: a total of 110 mesial roots of human mandibular fi rst molars were selected. twenty-seven roots were left unprepared as negativ...

Background:One of the main reasons for extraction of endodontically treated teeth is vertical root fracture (VRF). Some factors such as root canal treatment are involved in vertical root fracture because of their potential to weaken the tooth structure. Therefore, this study aimed to investigate the effect of combining different obturation materials and rotary systems on the fr...
