New Proposal for Classifying Root and Root Canal Morphology

, 2018
Understanding the anatomy of roots and root canals is fundamental for successful root canal treatment and endodontic surgery. There are numerous reports on anatomical variations of teeth, and several classifications of canal configurations have been ...

Root canal morphology of mandibular incisors

Journal of Endodontics, 1992
In this study, 100 mandibular central and lateral incisors were used to determine the number of root canals and their types, the ramifications of the root canal, the location of apical foramina, and the frequency of apical deltas. The teeth were immersed in India ink, decalcified, and cleared.

Root Canal Morphology of Mandibular Incisors with Double Root Canals in a Chinese Population.

The Chinese journal of dental research, 2020
To investigate the bilateral symmetry of double root canals, variation in root canal bifurcation and position of canal orifices in mandibular incisors in a Chinese population.A total of 149 subjects with mandibular incisors with two canals were selected from 866 patients based on CBCT images and divided into three groups: group 1 (< 21 years), group 2 (

Root canal morphology of maxillary premolars

Journal of Endodontics, 1998
The objective of this study was to investigate further internal anatomy of maxillary premolars. Six hundred recently extracted maxillary first and second premolar teeth were used in this study. One-half of the teeth were maxillary first premolars, the other half were maxillary second premolars.

Root and canal morphology of maxillary premolars and their relationship with the crown morphology

Journal of Oral Biosciences, 2022
To investigate the relationship between crown/root size and root/canal morphology of maxillary premolars.One hundred and thirty-three first (P1) and 110 second (P2) maxillary premolars were used. Mesiodistal and buccolingual diameters and root heights of P1 and P2 were recorded to the nearest 0.01 mm. The number of single and multi-rooted premolars was

A computerized method for the evaluation of root canal morphology

International Endodontic Journal, 1995
SummaryThe objective of this research was to develop a technique that would allow three‐dimensional imaging of root canals utilizing computer image processing. Ten single‐rooted permanent human teeth with mature apices were analysed. The teeth were decoronated and fixed on boards with the long axis of the root perpendicular to the board.

A computerized method for evaluating root canal morphology

Journal of Endodontics, 1986
Access was performed on nine extracted single-rooted permanent human premolars. Complete debridement of the root canal system was accomplished by running high volumes of NaOCl through them for 90 min. Volumes of the root canal system and access preparation were calculated for each specimen by weighing the teeth, filling them with contrast medium at a ...
