BACKGROUND The authors used an in vitro model to investigate the ability of an erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) laser with radial emitting tips to disinfect Enterococcus faecalis-infected dentin. MATERIALS AND METHODS The in vitro infected-dentin model system consisted of a dentin cylinder, prepared from a human anterior tooth root, cemented into a sealable two-ch...

Procedure related factors define the success of root canal procedures in majority of the cases. While there are several guidelines available, the compliance rate is substantially low. This study evaluates the attitudes, materials and methods preferred in root canal therapy by dentists in Palestine. An online self-administered questionnaire was sent to 200 Palestinian dentists. The questionnaire...

Aims During biomechanical preparation of the root canal system, the cutting action of instruments on dentine result in the formation of hard-tissue debris, which can be packed in some areas of the root canal system, mainly in anatomical variations as isthmus, branches and flattening (1, 2). Accumulated hard-tissue debris in the root canal system may compromise thorough disinfection and filling ...

Mucosal fenestration is a clinical condition where tooth root apices are visible in the oral cavity due to loss of overlying alveolar bone and mucosa. Mucosal fenestration mostly affect maxillary incisors. The present case series reports two cases where patient reported with complaint of unesthetic appearance because of exposed roots of maxillary anterior teeth which on radiographic examination...

This paper describes and discusses the use of the Nd:YAG and diode lasers in endodontics. Clinical studies clearly show advantages of laser treatments over currently-used conventional methods and techniques. The most important advantages are improved disinfection efficacy, more effective root canal cleaning, reduction of permeability, reduction of micro-leakage, and elimination of the need to u...

BACKGROUND Long term successful root canal treatment requires effective debridement and disinfection of root canal system. Persistent periradicular lesions are usually associated with Enterococccus faecalis. Prompt research for natural alternatives for irrigation is mainly due to the constant increase in antibiotic resistant strains and side effects caused by synthetic drugs. Sodium hypochlorit...

This review outlines the biological basis and clinical protocols currently used in regenerative endodontic procedures (REPs) and discuss future directions in pulp regeneration approaches. The treatment of immature teeth with REPs has been described as a 'paradigm shift' as there is the potential for further root maturation. Clinically, REPs involve disinfection of the root canal system without ...

Endo-perio lesions might be interdependent because of the vascular and anatomic connections between the pulp and the periodontium. The aim of this study is to emphasise that primary endodontic lesion heals after a proper instrumentation, disinfection and sealing of the endodontic space. The primary endodontic lesion with a secondary periodontal involvement first requires an endodontic therapy a...

INTRODUCTION The aim of the present in vitro study was to evaluate the disinfection ability of 980-nm diode laser in comparison with sodium hypochlorite (NaOCl) as a common root canal irrigant in canals infected with Enterococcus faecalis (E. faecalis). METHODS AND MATERIALS The root canals of 18 extracted single-rooted premolars were prepared by rotary system. After decoronation, the roots w...
