Vertical root fractures (VRF) in endodontically treated teeth have long been reported and pose diagnostic difficulties. A hemisection/root resection procedures removes the fractured fragments completely, and retains a portion of the compromized tooth offers a predictable treatment option. The key to this rests in ideal case selection involving balancing all indications and contraindications. Th...

The aim of this study was to evaluate the influence of calcium chloride (CaCl(2)) on the sealing ability of three Mineral Trioxide Aggregate (MTA) cements, ProRoot MTA, MTA-Angelus, and radiopaque White Portland cement (WPC), for retrograde root filling. Seventy roots of extracted single-rooted teeth were instrumented and obturated. After sectioning the samples at 2 mm from the apex, they recei...

Purpose: To evaluate the ability of BiodentineTM as a retrograde root-end filling in conjunction with a well-documented periapical surgery protocol in a clinical case series study. Material and Methods: Thirteen teeth in 13 patients referred for periapical surgery were included in the study. Teeth with obvious signs of root-fracture or apical-marginal communications were excluded from the study...

Research evolution regarding dental research determines the increase of patient's desire to preserve their dentition for a long time. The loss of a molar tooth as the last teeth present on the dental arch, raises issues regarding how the prosthesis should be placed, still patients are usually reluctant to use as last resort the prosthetic solution. This article describes the technique of root a...

AIM This randomized, controlled, clinical study was designed to evaluate the adjunctive effect of calcium sulphate grafts on the surgical treatment of through and through periradicular lesions. METHODOLOGY Twenty patients each with one tooth showing evidence radiologically of a periradicular lesion wider than 10 mm, with lack of both buccal and lingual cortical bony plates and an indication f...

OBJECTIVES To investigate apicectomies performed using burs, a CO2 laser or an Er:YAG laser and to evaluate the following aspects: morphology of apicectomized surfaces, presence of failures at the dentin/obturation material interface (marginal fit) of the apical portions of the root canals, and the proportions of chemical elements in the apicectomized surfaces. STUDY DESIGN Twenty-four teeth ...

INTRODUCTION In apical surgery, after apicoectomy and retro-preparation of canal, a retrofil material is applied to seal the apical region of the root canal. Mineral trioxide aggregate (MTA) is the gold standard material for this purpose. Changing water/powder ratios of MTA affects its properties. The purpose of this in vitro study was to determine the effect of liquid/powder ratio of retrofil ...

t s m r a o reservation of teeth has been the treatment of hoice and a fundamental principle of dentistry. In ontrast, the extraction of natural teeth has been onsidered undesirable because of the often limited ong-term success of the alternate prosthodontic relacements. To this end, heroic efforts have been ade to preserve teeth, ranging from advanced enddontic and periodontal therapy (includi...

This case report demonstrates an unnecessary endodontic treatment of teeth with florid cemento-osseous dysplasia (FCOD) due to a misdiagnosis as periapical pathosis and emphasizes the importance of correct diagnosis to avoid unnecessary treatment. A 30-year-old woman was referred to our institution for apicoectomies of the mandibular left canine and both the lateral incisors. The periapical les...

A variety of pain resembling the lightning pains of tabes dorsalis is described in patients suffering from persistent sciatica, following laminectomy for lumbar disc disease. It occurs in about 13% of those complaining of post-laminectomy pain and in 5% of all those having a laminectomy for disc disease. It is associated with damage to the nerve root and may be precipitated by nerve root resect...
