The present study was conducted to determine the number of roots and morphology of the root canal system of permanent mandibular first molars (M1) in a Sri Lankan population. Sample of 529 M1 teeth was used. The number of roots was examined and the lengths of the mesial and distal roots were measured to the nearest 0.01 mm. Vacuum injection protocol was used to inject China ink into the root ca...

AIM To analyse the regenerative potential of leucocyte- and platelet-rich fibrin (L-PRF) during periodontal surgery. MATERIALS AND METHODS An electronic and hand search were conducted in three databases. Only randomized clinical trials were selected and no follow-up limitation was applied. Pocket depth (PD), clinical attachment level (CAL), bone fill, keratinized tissue width (KTW), recession...

OBJECTIVE The aim of this study was to evaluate the minimum residual root thickness (MRRT) of the danger zone after preflaring of the mesio-buccal (MB) canal of mandibular first molars using ProTaper, RaCe and Gates-Glidden (GG) drills as coronal shapers by cone beam computerized tomography (CBCT). MATERIALS AND METHODS In this experimental study, the initial CBCT scans of 75 MB canals of man...

AIM The aim of this pilot study was to analyze the interfurcal bone height in relation to the possible need for subsequent sinus floor elevation in patients with advanced periodontitis and furcation involvement of first and/or second maxillary molars. MATERIAL AND METHODS Seventeen dentate patients, who received cone beam computed tomography (CBCT) for detailed preoperative diagnosis and plan...

Polymethyl methacrylate (PMMA), commonly known as bone cement, is widely used in orthopaedic surgery, mainly for prosthesis fixation, stabilizing compressive vertebral fracture or filling defects. Bone cement a potentially new repair material that has been investigated recently dentistry because of its properties like low cytotoxicity, excellent biocompatibility and resistance to moist environm...

One of the significant iatrogenic complications during endodontic treatment is Furcal perforations which may lead to failure. Mineral trioxide aggregate (MTA) has been regarded as an ideal material for perforation repair. This case report describes repair furcal in a young permanent mandibular molar 10year-old male patient using MTA. The tooth was treated endodontically followed by placement zi...

BACKGROUND Many clinical studies have demonstrated that guided tissue regeneration (GTR) is a successful treatment modality of periodontal reconstructive surgery and it has become an accepted procedure in most periodontal practices. RATIONALE The purpose of this structured review was to assess the efficacy of guided tissue regeneration (GTR) procedures in patients with periodontal osseous def...
