Mesiodistal and buccolingual
roentgenographic investigation of 7,275 root canals.
Chadwick BL, Dummer PM, van der Stelt PR The effect of alterations in horizontal X-ray beam angulation and buccolingual
cavity width on the radiographic depth of approximal cavities.
This study seeks to relate the transversal maxillomandibular discrepancy with the buccolingual
inclination of first maxillary and mandibular permanent molars in a population of patients aged 10 to 16 years, by means of CBCT.
width of the preparation was kept 3 mm and the axial wall was prepared to a depth of 1.
A pre-operative radiograph was obtained in the buccolingual
and mesiodistal directions using a digital technique to measure the root curvature according to the Schneider method (17).
expansion was reported in approximately two-third of the patients (19).
TD is an involuntary movement disorder characterized by complex repetitive neck, buccolingual
and sometimes generalized stereotypic hyperkinetic features.
Morphological Analysis on CT scan: The thickness of the regenerated bone was viewed in the buccolingual
, axial and panoramic view images and evaluated as thicker, almost the same, or thinner than the adjacent native bone in each case and also the bone density was measured in Hounsfeild units on CT-Scans at 6 months.
This difference can be explained by the difference in the buccolingual
dimension between primary and permanent canines, as exfoliation of the primary canines occurred in two patients of the EG.
Once it touched bone, it was withdrawn slightly and constantly moved vertically (apicocoronal), up and down the pocket, and side to side (either buccolingual
or mesiodistal depending on location of the pocket), with slow smooth sweeping motions.
In this study, CBCT was used to evaluate the edentulous alveolar mucosal thickness in the buccolingual
section with varying tooth positions in the mandible for analyzing the mucosal thickness distribution, and to provide an experimental basis for the biomechanical study of complete denture support system.
Digital periapical radiographs (IDA, Dabi Atlante, Ribeirao Preto, Brazil) were taken in the buccolingual
and mesiodistal directions to select only teeth with complete formation of the apex, absence of endodontic treatment and presenting single, oval-shaped root canals, with a cross-section diameter ratio of [greater than or equal to] 2.
