introduction: coronal anatomic variations in permanent maxillary molars are unusual; conversely variations involving the number of root canals or number of roots are more common. methods and materials: this case report presents a successful nonsurgical endodontic therapy of left maxillary first molar with three roots and seven root canals. this unusual morphology was diagnosed using a dental op...

iatrogenic perforation of the furcation area in multi-rooted molars during preparation of the access cavity can potentially lead to tooth extraction. the present case report describes the nonsurgical endodontic management of an extensive pulp chamber floor perforation in a first mandibular molar with calcium enriched mixture (cem) cement. the perforation was chemically cleaned and then physical...

introduction : to evaluate the clinical and radiographic outcomes of pulpotomy treatment with mineral trioxide aggregate (mta) in symptomatic mature permanent teeth with carious exposure. materials and methods: ten patients aged 27-54 years presented with 11 symptomatic permanent teeth ( n =11). each offending carious tooth was clinically and radiographically determined. we removed caries as co...

Introdouction: Canal length measurement is essential for proper endodontic treatment. Any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. Digital radiography has enabled accurate measurement of curved canal length. In this study, we evaluated the accuracy of calibration of a complementary m...

An accurate understanding of the morphology of the root canal system is a prerequisite for successful root canal treatment. Invaginated teeth have a complex root canal configuration that cannot be instrumented effectively and should be treated by both endodontic therapy and surgery. A case of dens invaginatus Type 3 in a maxillary lateral incisor with a periapical lesion and its successful trea...
