Length and Geometric Patterns of the Greater Palatine Canal Observed in Cone Beam Computed Tomography
greater palatine canal
2014/11/6
The greater palatine canal is an important anatomical structure that is often utilized as a pathway for infiltration of local anesthesia to affect sensation and hemostasis. Increased awareness of the ...
Facial Soft-Tissue Asymmetry in 3D Cone Beam Computed Tomography Images of Children with Surgically Corrected Unilateral Clefts
soft-tissue depth facial reconstruction cleft lip with or without cleft palate
2014/11/6
Cleft lip with or without cleft palate (CL/P) is a relatively common craniofacial malformation involving bony and soft-tissue disruptions of the nasolabial and dentoalveolar regions. The combination o...

Computed tomography is the choice technique to assess oral and maxillofacial osseous lesions because it provides hard and soft tissues visualization in one examination without superimposition of surro...
Analysis of Internal Defects in All-ceramic Crowns Using Micro-focus X-ray Computed Tomography
MicroCT All-ceramic crown Internal defect
2009/9/14
The purpose of this study was to examine all-ceramic crowns for internal defects using micro-focus X-ray computed tomography (microCT). Mono-ceramic CAD/CAM crowns, ceramic-core CAD/CAM crowns, and he...
Three-dimensional Changes of the Mandible and Alveolar Bone in the Ovariectomized Rat Examined by Micro-focus Computed Tomography
alveolar bone micro-focus computed tomography (μCT) three dimension (3D) osteoporosis ovariectomy
2009/5/27
To clarify the changes of the mandible and alveolar bone in postmenopausal osteoporosis, we examined the changes of structure in mandible and alveolar bone of ovariectomized (OVX) rats. Twelve female ...
Relationship between the Bone Mineral Density of Mandible by Quantitative Computed Tomography and Lumbar Spine by Dual Energy X-ray Absorptiometry
quantitative computed tomography (QCT) mandible bone mineral density (BMD) osteoporosis periodontal disease
2009/5/27
Osteoporosis is a systemic skeletal disorder characterized by low bone mass. Periodontitis is an inflammation of the supporting tissues of the teeth, usually leading to loss of alveolar bone. The purp...
