“…Computed tomography (CT) and cone-beam computed tomography (CBCT) allow us to handle images three-dimensionally, and are now widely used for planning and evaluating various dental treatments, [1][2][3][4] such as orthognathic surgery [5][6][7][8] and orthodontic treatment. [9][10][11][12] Some procedures have been proposed for three-dimensional (3D) measurements and are also applied to cephalometric analysis, which has the potential to replace traditional two-dimensional (2D) cephalometric evaluation.…”

Objective: To compare the reproducibility of landmark identification on three-dimensional (3D) conebeam computed tomography (CBCT) images between procedures based on traditional cephalometric definitions (procedure 1) and those tentatively proposed for 3D images (procedure 2). Materials and Methods: A phantom with embedded dried human skull was scanned using CBCT. The acquired volume data were transferred to a personal computer, and 3D images were reconstructed. Eighteen dentists plotted nine landmarks related to the jaws and teeth four times: menton (Me), pogonion (Po), upper-1 (U1), lower-1 (L1), left upper-6 (U6), left lower-6 (L6), gonion (Go), condyle (Cd), and coronoid process (Cp). The plotting reliabilities of the two procedures were compared by calculating standard deviations (SDs) in three components (x, y, and z) of coordinates and volumes of 95% confidence ellipsoid. Results: All 27 SDs for procedure 2 were less than 1 mm, and only five of them exceeded 0.5 mm. The variations were significantly different between the two procedures, and the SDs of procedure 2 were smaller than those of procedure 1 in 21 components of coordinates. The ellipsoid volumes were also smaller for procedure 2 than procedure 1, although a significant difference was not found. Conclusions: Definitions determined strictly on each three sectional images, such as for procedure 2, were required for sufficient reliability in identifying the landmark related to the jaws and teeth.

“…Coronectomy or intentional root retention is associated with chances of infection due to retained pulp tissue [2,3,10] and is a controversial issue [10]. Also, the concept is relatively new, has no long term studies supporting it [10] and seems too conservative to the authors because of the concept of retaining a tissue which is indicated for removal.…”

“…Also, the concept is relatively new, has no long term studies supporting it [10] and seems too conservative to the authors because of the concept of retaining a tissue which is indicated for removal. This paper stands against the concept of doing a coronectomy for all cases showing radiographic proximity to the IAC, due to above mentioned reasons and proposes that, only those cases where intraoperatively severe bleeding is encountered be taken up for root retention if complete removal is found to be impossible without further damaging the nerve.…”

Introduction The safe removal of third molars involved with the inferior alveolar canal (IAC) has been an area of concern since long. Many times we hesitate for the removal of third molars, fearing injury to the inferior alveolar nerve. Materials and Methods The authors here describe a simple technique which can be used to remove third molars showing evidence of proximity to IAC on presurgical radiographic evaluation, as well as those root tips which, during removal, accidentally enter the IAC space. Conclusion A step-by-step protocol is presented along with necessary precautions during the operative procedure.

“…A indicação desta técnica é justificada pelos riscos em potencial que uma extração pode gerar, tais como lesão ao nervo, infecção, dor e alveolite (RENTON, et al, 2005;HATANO et al, 2009;CHEUNG, 2009;CILASUN et al, 2011).…”
