AIM The aim of the study was to assess the prevalence of apical periodontitis (AP) and quality of root canal fillings in an adult Moroccan subpopulation. METHODS In the study 508 patients were included, attending the Conservative Dentistry Clinic at the Faculty of Dentistry of Casablanca. 508 panoramic and 709 periapical radiographs were observed. The periapical status of all teeth (with the ...

UNLABELLED The aim of this study was to investigate the technical quality of root fillings in root filled teeth, their association with periapical status and prevalence of apical periodontitis. MATERIAL AND METHODS The sample consisted of 83 subjects, presenting consecutively as new patients seeking dental care (prosthetic, endodontic and cariologic treatment) in the years 2005/2006. Clinical...

introduction: there is substantial evidence that the technical quality of root canalfilling has a significant effect on the outcome of root canal treatment. theaim of this study was to evaluate the technical quality of root canal fillingsperformed by dental students. methods: the records of 325 teethradiographs, treated by dental students in 2008-2009 in babol dental school,were selected and ev...

AIM To compare the long-term apical sealing ability of gutta-percha/AH Plus and Resilon/Epiphany. METHODOLOGY The root canals of 90 single-rooted human mandibular premolars with single narrow root canals were prepared with ProFile 0.4 taper instruments to apical size 40. After each instrument, the canals were irrigated with 1% sodium hypochlorite. Subsequently, the teeth were randomly divided...

This paper describes an operated oblique facial cleft case with external inflammatory root resorption (EIRR) of the permanent maxillary left incisors and canine in a 12-year old patient. Due to the facial oblique cleft, the plastic surgery department operated on the patient five times and placed her on fixed orthodontic therapy. EIRR treatment of the maxillary left incisors and canine was perfo...

PURPOSE The aim of this audit was to evaluate the technical quality of undergraduate de novo endodontic competence cases in the Dublin Dental University Hospital (DDUH) compared to European standards. MATERIALS AND METHODS A radiographic analysis of the number of canals in student 'competence' cases (completed 2009-2010) that met the accepted technical criteria for an ideal root canal treatme...

The effect of different storage solutions on surface topography of mineral trioxide aggregate (MTA) and new experimental cement (NEC) as root-end fillings was investigated. Twenty-four single-rooted teeth were cleaned, shaped and obturated in a same manner. After root-end resection, 3-mm deep root-end cavities were ultrasonically prepared. Samples were randomly divided into four test groups (A1...

OBJECTIVES The purpose of this in vitro study was to assess the effect of root canal preparation size and taper on the amounts of glucose penetration. MATERIAL AND METHODS For conducting this experimental study, eighty mandibular premolars with single straight canals were divided randomly into 2 experimental groups of 30 samples each and 2 control groups. Using K-files and the balance force t...

OBJECTIVE This study compared the influence of three epoxy resin-based sealers with distinct radiopacities on the observers' ability to detect root canal filling voids during radiographic analysis. MATERIAL AND METHODS The root canals of 48 extracted maxillary canines were prepared and divided into three groups. Each group was laterally condensed with one sealer (AH Plus®, Acroseal® or a non-...
