3-Dimensional Analysis and Systematic Review of Root Canal Morphology and Physiological Foramen Geometry of 109 Mandibular First Premolars by Micro-computed Tomography in a Mixed Swiss-German Population.

Journal of Endodontics, 2020
INTRODUCTION The aim of this study was to systematically revise the root canal configuration (RCC) literature and to investigate the root canal morphology of mandibular first premolars (Ma1Ps) of 2 populations by means of micro-computed tomographic ...

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 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 ...

Symmetry of root anatomy and root canal morphology in maxillary premolars analyzed using cone-beam computed tomography.

Archives of Oral Biology, 2018
OBJECTIVE This study aimed to use cone-beam computed tomography (CBCT) to evaluate the root anatomy and canal morphology of maxillary premolars in a Chinese population and determine their degree of bilateral symmetry.

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 ...

[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.

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 ...
