The purpose of this study was to test a gallium nitrate solution, a resorption inhibitor, employed as a root canal dressing in teeth submitted to late replantation. Thirty maxillary right central incisors of rats were avulsed and kept dry for thirty minutes. The teeth were instrumented and the root surfaces were treated with 1% hypochlorite solution followed by application of 2% sodium fluoride...

The aim of the present study was to evaluate the effect of calcium hydroxide dressing on the bond strength of three commercially available endodontic sealers (MTA Fillapex, Sealapex, and AH Plus) to root canal dentin. Sixty slices of extracted human canines were obtained from cervical, middle, and apical root thirds. Root canals were standardized and specimens were filled and divided into six g...

AIM To assess the presence of Enterococcus faecalis after root canal treatment in single or multiple visits in an ex vivo model. METHODOLOGY Forty-five premolar teeth were infected ex vivo with E. faecalis for 60 days. The canals were then prepared using a crowndown technique with System GT and Gates-Glidden burs and irrigated with 2% chlorhexidine gel. The specimens were divided into five gr...

he objective of this study was to evaluate the influence of calcium hydroxide in intracanal dressing on the ability of the dyes rhodamine B and methylene blue to label the dentine. Forty extracted human mandibular premolars had their canals instrumented and were divided into four groups: in two groups, the canals were filled with a calcium hydroxide paste and the others remained in distilled wa...

AIM The purpose of this prospective clinical study was to discover clinically the influence of Pulpotec® (Produits Dentaires S.A., Switzerland) on the incidence of inter-appointment flare-up, with a view to advance the resolution of pain and/or swelling in patients presenting for emergency root canal treatment. METHOD In a prospective randomized clinical trial, pulpotec paste was used as an i...

Neuroblastoma is a nervous system malignancy. The extension of intra-abdominal neuroblastoma to the spinal canal is a rare condition. In this case report, we present a patient with monoplegia and a huge intra-abdominal mass with intra spinal extension and cord compression.

We present 2 cases of intra-arterial injection of endodontic calcium hydroxide via the root canal system of molar teeth. Nonsetting calcium hydroxide paste was used as a temporary dressing during endodontic treatment and in both cases delivered via an injectable syringe technique. Retrograde flow of the calcium hydroxide occurred along the artery until its origin where orthograde flow continued...

OBJECTIVES Patients with Type I neurofibromatosis scoliosis with intra-canal rib head protrusion are extremely rare. Current knowledge regarding the diagnosis and treatment for this situation are insufficient. The purpose of this study is to share our experience in the diagnosis and surgical treatments for such unique deformities. METHODS Six patients with Type I neurofibromatosis scoliosis w...

This study evaluated the clinical efficacy of 2% chlorhexidine (CHX) gel on intracanal bacteria reduction during root canal instrumentation. The additional antibacterial effect of an intracanal dressing (Ca[OH](2) mixed with 2% CHX gel) was also assessed. Forty-three patients with apical periodontitis were recruited. Four patients with irreversible pulpitis were included as negative controls. T...
