Root Canal Morphology of Permanent Three-rooted Mandibular First Molars: Part II—Measurement of Root Canal Curvatures

Journal of Endodontics, 2010
The distolingual (DL) roots of three-rooted mandibular molars often challenge clinicians during root canal therapy. This study investigated canal curvatures in permanent three-rooted mandibular first molars by using micro-computed tomography (micro-CT) scans.Twenty three-rooted (group 1) and twenty-five two-rooted mandibular first molars (group 2) were

Root and canal morphology of Indian maxillary premolars by a modified root canal staining technique

Odontology, 2011
The aim of this study was to investigate the root and canal morphology of maxillary first and second premolars in Indians by a modified canal staining and tooth clearing technique. Maxillary first (350) and second (350) premolars were collected, and the morphology and number of roots analyzed.

Anatomy and Root Canal Morphology

2015
The majority of endodontic failures can often be attributed to the inability of localising and treating all the canals of the root canal system. Root canal systems are commonly complex with the teeth often having lateral ramifications, extra roots or additional canals.

[Root canal morphology of deciduous tooth].

Hua xi kou qiang yi xue za zhi = Huaxi kouqiang yixue zazhi = West China journal of stomatology, 2015
To find out the morphological regularity of root canal in the primary tooth.Through transparent specimen of a set of deciduous teeth, the shape of root canal was observed under stereomicroscope.Among the deciduous anterior teeth, 92% were single canal except for one single-double mixed canal.

Root Canal Morphology of Permanent Three-rooted Mandibular First Molars—Part I: Pulp Floor and Root Canal System

Journal of Endodontics, 2010
Racial variations in root form and canal anatomy present endodontic challenges for clinicians. This study examined root canal morphology of three-rooted mandibular first molars by micro-computed tomography scans.A total of 122 extracted mandibular first molars were collected from a native Chinese population.

Root canal morphology of the human mandibular first molar

Oral Surgery, Oral Medicine, Oral Pathology, 1971
Abstract Forty-five plastic casts of the root canals of extracted human mandibular first molars were fabricated and studied. In approximately one third of the teeth, there were four root canals. When a root contained two root canals, they either remained two distinct canals with separate apical foramina, united to form a common apical foramen, or ...

Root canal morphology of the human maxillary second premolar

Oral Surgery, Oral Medicine, Oral Pathology, 1974
Abstract Two hundred human maxillary second premolars were decalcified, injected with dye, and cleared in order to determine the number of root canals and their different types, the curvature of the roots and root canals in all directions, the ramifications of the main root canals, the location of the apical foramina and transverse anastomoses, and ...

Root canal morphology of mandibular first and second premolars

Oral Surgery, Oral Medicine, Oral Pathology, 1973
Abstract A total of 1,393 first and 938 second mandibular premolars were radiographically examined and mechanically probed to determine the percentage of these teeth which had more than one root canal. A second or third canal existed in at least 23.1 per cent of the first mandibular premolars and in at least 12.1 per cent of the second mandibular ...

Aberrant root canal morphology in a maxillary second molar

Australian Dental Journal, 1983
Abstract— Abberations in root canal morphology of maxillary permanent molars often occur as collateral mesio‐buccal canals and, less commonly, as separate root canals in divergent palatal roots. This case report describes a right maxillary second molar with both types of anomaly common to the maxillary first molar and a collateral disto‐palatal canal ...
