This study aimed at providing a gauge device (Ekontak et al Gauge K-Device) in order to analyze the forces applied to teeth and periodontal tissues during dental practices in vitro. This force gauge device can be used in the investigation of the possible defect generation to tooth structures when overloaded forces are applied during dental procedures in vitro. Ekontak et al Gauge K-Device consi...

PURPOSE This retrospective study evaluated the clinical and radiographic status of nonsurgical endodontic treatment (ET) of anterior and posterior teeth in HIV-seropositive patients. METHODS ET was analyzed in 26 anterior and 34 posterior teeth from 54 consecutive HIV patients (gender ratio 3 Male : 1 Female, mean age 40.2 years, mean CD4 240, CD4<500 in 88%, 12 with AIDS) over a six year per...

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-d...

OE — Volume 32, Number 4, April 2006 he final objective of endodontic procedures should be the total obturation of the root canal space. Biologic necessity requires the elimination of the protein degradation roducts, bacteria, and bacterial toxins which emanate from necrotic and gangrenous oot canals. While these irritants may be eliminated by extraction of the tooth, the health f the dentition...

The aim of this study was to assess the effect of three root canal irrigation solutions on the apical sealing ability of three root canal obturation materials: gutta-percha/AH plus or MM-seal and Resilon/Epiphany SE. A total of 100 teeth with single straight root canals were randomly divided into three equal groups of 30 samples each, with the other 10 teeth (5 positive and 5 negative) used as ...

This study compares the effectiveness of ProTaper rotary files with ProTaper retreatment and K-files in the removal of Resilon or gutta percha (GP) from canals filled either by cold lateral condensation or thermal obturation using micro-CT. Ninety-six teeth were prepared using ProTaper files and allocated into four groups (n=24): Group-1 was filled with GP/AH-Plus and Group-2 with Resilon/RealS...

The aim of this study was to compare the volume of voids in a resin-based root canal filling (Resilon) with gutta percha using either cold lateral condensation or continuous wave of compaction filling techniques using computed X-ray micro-tomography (micro-CT). A total of 56 extracted upper anterior human teeth were decoronated, the canals shaped using rotary ProTaper files to a final size of F...
