introduction: transportation is an important iatrogenic endodontic error which might cause failure. this study evaluated the canal transportation caused by neoniti and protaper instruments, using cone-beam computed tomography (cbct) cross sections. methods and materials: this in vitro experimental study was performed on 40 mesiobuccal roots of maxillary first molars. the teeth were scanned with...

the most difficult maxillary teeth for endodontic treatment are the maxillary first molars (mfm) due to their complex root canal anatomy. the presence of two roots and c-shaped canals in mfms has been reported in rare cases. the present case reports root canal treatment of mfm with two roots, where the palatal and buccal roots were joined together in a c-shaped configuration .

Case selection and treatment plan are important aspects of endodontic treatment. Dentists should organize the treatment plan based on their knowledge, abilities, skills and more importantly the patients' preference and dentition. Indubitably, the treatment plan for each patient is exclusive and "tailor-made" and cannot be used for all patients. Dentists' selfestimation of their abilities opens ...

introduction: bacterial infection of tooth pulp can progress into periapical diseases. root canal treatment has been established as the best treatment. in cases of failure, nonsurgical retreatment of teeth is preferred to surgical procedure and extraction. materials & methods: in this historical cohort study, 104 permanent teeth with apical lesion were treated during 2002-2008. all teeth showed...

in endodontics, severe involuntary gagging can have a severe impact on treatment procedure. there are many ways to ease the gag reflex, one of which is hypnosis. a 34-year-old male was referred for root canal treatment of a molar tooth. he had not received any dental treatments for the past nine years due to fear of severe gag reflex. three hypnotic sessions based upon eye fixation, progressive...

introduction: this study compared the root canal microbial count of necrotic teeth after irrigation with 6% sodium hypochlorite (naocl) (single session treatment) and two-session root canal treatment with two-week application of calcium hydroxide (ch) mixed with 0.2% chlorhexidine (chx) as intracanal medicament. methods and materials: in this randomized clinical trial, single-rooted necrotic te...

for management of a symptomatic maxillary lateral incisor with dull pain on chewing, suppurative sinus tract, defective metal-ceramic crown and iatrogenic internal root resorption, an interdisciplinary approach was taken. two-visit nonsurgical treatment with calcium-enriched mixture (cem) cement, replacement of metal-ceramic crown with all-ceramic crown and corrective periodontal plastic surger...

introduction: effective post-operative pain management is one of the problems following root canal treatment. nonsteroidal anti-inflammatory drugs (nsaids) are the most commonly prescribed analgesics in endodontics. the aim of this study was to evaluate the effectiveness of naproxen in controlling pain following root canal treatment in teeth with irreversible pulpitis. materials and methods: th...

root fractures are defined as fractures involving dentine, cementum, and pulpal and supportive tissues. they comprise about 0.5–7% of all dental injuries. horizontal root fractures are commonly observed in the maxillary anterior region and 75% of these fractures occur in the maxillary central incisors. case report: this case report is about a 26-year-old male referred to the endodontic departme...
