Root resection therapy has been used in the treatment of advanced periodontal disease for nearly 100 years. The preservation of posterior abutment teeth permits oral rehabilitation with fixed bridges instead of removable prosthesis. A case of iatrogenic removable partial denture in relation to 47, causing bone loss till the apex of distal root of 46 came to the department of Periodontics, Sri S...

In this study, we hypothesized that herpes viruses, EBV and/or HCMV contribute to endodontic disease via herpes virus–bacterium–host response interactions. In our in vitro study, we investigated potential pathogenic interactions between Epstein-Barr virus (EBV) and the Gram-positive bacterium, Enterococcus faecalis. In our in vivo study, we hypothesized that individuals with symptomatic endodon...

CASE REPORT This case report describes the outcome of a number of retreatments on a failed root filling in a maxillary first molar. The patient wanted all amalgams replaced by tooth-coloured Cerec restorations, including one in a symptomless maxillary molar. This tooth had a pulpotomy or a poorly done root-canal treatment 10 years earlier. The molar was root-canal retreated before placing the C...

The present investigation was designed to evaluate the long-term effect of root-resective therapy in the treatment of furcation-involved molars. The patient sample included 72 patients, 21-62 years of age, who presented periodontal lesions in the posteriors segments of the mouth including furcation involvement of various degrees. After an initial examination, each patient was subjected to a ser...

Successful treatment of furcated molar teeth presents the periodontist and prosthodontist with a challenging dilemma. Accepted treatment modalities include chemotherapeutic maintenance, root planning, open flap debridement, modified Widman flap, bone grafting with and without guided tissue regeneration, and osseous resection with and without root removal. Determining the appropriate treatment f...

OBJECTIVES The aim of this study was to determine the apical surface characteristics and presence of dental cracks in single-rooted premolars, resected 3.0 mm from the root apex, using the Er: YAG laser, tungsten carbide bur, and diamond-coated tip, by scanning electron microscopy (SEM). EXPERIMENTAL DESIGN Thirty single-rooted premolar teeth were collected. The instrumented and obturated tee...

Introduction. Vertical root fracture (VRF) is one of the most frustrating complications of root canal treatment. The prognosis of the root with VRF is poor therefore tooth extraction and root amputation are usually the only treatment options. However, bonding of the fracture line with adhesive resin cement during the intentional replantation procedure was recently suggested as an alternative to...

OBJECTIVE This study investigates the effects of Nd:YAG laser irradiation combined with different irrigation protocols on the marginal seal of root fillings. BACKGROUND DATA Limited information exists regarding the effects of morphologic changes to root canal (RC) walls after Nd:YAG laser irradiation after smear-layer removal with EDTA on the sealing ability of root fillings. METHODS The 75...

BACKGROUND/OBJECTIVE Progress in endodontic techniques and methodological advances have altered root canal therapy over the last decades. These techniques and methods need periodical documentation. This observational study determined the current prevalence of endodontic treatments, and investigated the relationship of various factors with the periapical status in a Lower Austrian subpopulation....

OBJECTIVE To compare three various methods in the diagnosis of dentinal cracks formed in the apical third after root resection. MATERIALS AND METHODS One hundred extracted human maxillary central incisors were selected. The root canals were prepared with step-back technique. Then 3mm from the apical end of all roots was cut perpendicular to the long axis of the tooth. The apical end of each r...
