The success of endodontic treatment is greatly affected by the location root canals. purpose this study was to evaluate and canal morphology permanent maxillary first second molars in a Polish population using cone-beam computed tomography scanning. Cone-beam (CBCT) scans maxilla were examined. number roots canals, frequency additional canals (MB2) mesiobuccal determined. results subjected statistical analysis chi-square test or with Yates' correction. A total 112 CBCT images (n = 185) 207)...

The aim of this study was to assess the radiographic features and factors affecting long-term results root canal treatment in Lódź region Poland.Three hundred fifty-five periapical radiographs previously endodontically treated teeth (282 root-filled 73 with pulpotomy) from 236 patients were evaluated study. aged 15 76 years randomly selected amongst subjects referred Institute Dentistry. Medical University two private dental practices. examined by authors according criteria proposed De Cleen...

Pulp stones (PSs) are calcified masses that can be found in the pulp cavity of any deciduous or permanent tooth.They observed healthy, diseased, and even unerupted impacted teeth.Calcifications within may lead to a poorer outcome root canal procedure, as they block access canals, hinder their subsequent cleaning shaping.The paper describes 4 clinical cases denticles located coronal radicular pulp.Therapeutic me thods PS removal with different techniques instruments discussed.Specialist...

The aim of this study was to evaluate the root and canal morphology permanent maxillary first premolars in a Polish population using cone-beam computed tomography scanning (CBCT) compare classifications by Vertucci Ahmed et al. Images 350 were analyzed. Scans obtained from 226 patients: 131 women 95 men. configurations classified according new system In addition, number roots level where bifurcated identified. results submitted statistical analysis. Most had two (69.1%). bifurcations located...

The aim was to evaluate the morphology of maxillary second premolars. root canal configurations were classified according Vertucci and a new system by Ahmed et al. based on CBCT images. In addition, number roots level where they bifurcated identified, morphological measurements performed anatomical landmarks. Single-rooted forms most common. Bifurcation occurred often in middle part root. common configuration type I code 1 SP1 classification. showing results as follows (mm): palatal...

The aim of this study was to evaluate the sealing ability three different canal filling techniques. Sixty-four roots extracted human maxillary anterior teeth were prepared using ProTaper® rotary instruments. specimens then randomly divided into 3 experimental groups (n = 16) and 2 control 8). root canals filled cold lateral compaction (CLC group), continuous wave condensation technique Elements Obturation Unit® (EOU ProTaper obturators (PT group). For negative group, 8 as in CLC covered...

Background.The nickel-titanium alloy used in the production of files contains approx.56% nickel and 44% titanium by weight.To improve properties files, manufacturers introduce some innovations process.Their purpose is primarily to decrease stiffness instruments while increasing resistance cyclic fatigue, which reduces risk file separation.One most popular processes heat treatment alloy.Objectives.The aim research was determine influence manufacturing process rotary on shaping L-shaped...

Background. Successful root canal treatment is associated with correct preparation. The quality of mechanical preparation depends on many factors. Researchers are still looking for the optimal methods and instruments this purpose.Objectives. aim research project was to analyze structure work files effect simulated a single curvature.Material Methods. study involved reciprocal files: WaveOne® (Dentsply Maillefer) Reciproc® (VDW) rotary file ProTaper Next® Maillefer). used 30 resin blocks...

Background. Microorganisms surviving in the root canal system despite chemomechanical preparation are main reason for reinfection and endodontic treatment failure. The introduction of laser-assisted endodontics resulted higher success rates less recurrent infections.Objectives. To compare antibacterial action diode laser irradiation (CV – 1500 W, IMP 3000 W), photoactivated disinfection (PAD), 5.25% sodium hypochlorite (NaOCl) on Enterococcus faecalis an infected tooth model.Material...

Purpose . To evaluate the percentage content of gutta-percha, sealer, and voids in a filled canal area following three different filling techniques, using microphotographs Nis Elements® software. Material Methods After completing chemomechanical preparation, teeth (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mi>n</mml:mi><mml:mo>=</mml:mo><mml:mn fontstyle="italic">48</mml:mn></mml:math>) were randomly divided into groups...

Background. Chemomechanical preparation of the root canal system is a key factor in endodontic therapy. It also important to maintain integrity and localization anatomical structures apical region avoid excessive weakening as result errors which occur during preparation. One challenges treatment canals with high degree curvature. Nowadays, many nickel-titanium instruments have been introduced, thereby increasing efficiency safety preparation, compared stainless steel hand files.Objectives....

Abstract Introduction Determining the length of a root canal is significant outcome predictor for endodontic treatment. The aim this retrospective, clinical study was to evaluate accuracy working (WL) determination using pre-existing conebeam computed tomography (CBCT) images and compare them with data WL determined an electronic apex locator (EAL) in treated teeth, found patient records. Materials methods Thirty five medical records patients who underwent treatment (RCT) by endodontist...
