Periapical lesions of endodontic origin may develop asymptomatically and become extensive. Treatment options to manage such lesions range from non-surgical root canal treatment and/or apical surgery to extraction. A high percentage of complete and partial healing of extensive perapical lesions following conventional endodontic therapy has been reported. The case reports in this article describe...

Apical periodontitis is a chronic inflammatory disorder of periradicular tissues caused by aetiological agents of endodontic origin. Persistent apical periodontitis occurs when root canal treatment of apical periodontitis has not adequately eliminated intraradicular infection. Problems that lead to persistent apical periodontitis include: inadequate aseptic control, poor access cavity design, m...

OBJECTIVES The main disadvantage of fiber posts is their low bond strength to root canal wall. The aim of the present study was to assess the effect of different root canal post space treatments on push-out bond strength of fiber posts to root canal dentin. MATERIALS AND METHODS After post space preparation in 40 endodontically treated human premolars, the teeth were randomly divided into fou...

BACKGROUND Previous reports indicate that worldwide, the technical quality of root canal fillings is poor. There are few reports from sub-Saharan Africa and none yet from Nigeria where most patients access treatment from non-specialists especially at general dental clinics. The aim of this study was to evaluate the technical quality of root canal fillings done in a general dental clinic with em...

Method Only single-rooted teeth from the anterior maxillary and mandibular sextants were included within this audit. All treatment cases included within these audit cycles were assessed, treatment-planned and treated in accordance within the guidelines set by the strict surgical protocol determined in Part One of this series. Exclusion factors from the audit were: posterior teeth, those whose t...

INTRODUCTION Bacteria and their byproducts are major etiologic factors in endodontic diseases. Prevention or reduction of root canal bacterial contamination is the main aim of endodontic treatment. The purpose of this in vitro study was to evaluate the effect of size and taper of master apical file (MAF) in reducing bacteria from the apical third of the curved canals using a quantitative scanni...

Abstract Objective: Endodontically treated teeth with inadequate crown structure need a radicular post to help restore the tooth to proper function. Therefore, finding an efficient and timely method for preparing the post space in a way that causes less change in the amount of apical flood of the canal, has been the subject of various discussions and researches for many years. In this study, ...

BACKGROUND Root canal preparation using rotary nickel-titanium instruments has been reported to be superior to hand instrumentation in terms of root canal shape, centring and frequency of procedural errors. The purpose of this study was to evaluate canal preparations using a sequential silicone impression technique to assess root canal morphology. METHODS Pre-operative canal impressions were ...
