Accuracy in the Diagnosis of the Mental Nerve Loop: A Comparative Study Between Panoramic Radiography and Cone Beam Computed Tomography International Journal of Morphology
Couto-Filho,Carlos Eduardo Gomes do; Moraes,Paulo Hemerson de; Alonso,Maria Beatriz Carrazzone; Haiter-Neto,Francisco; Olate,Sergio; Albergaria-Barbosa,José Ricardo de.
Dental implant and chin osteotomy are executed on the mandible body and the mental nerve is an important anatomical limit. The aim of this research was to know the position of the mental nerve loop comparing result in panoramic radiography and cone beam computed tomography. We analyzed 94 hemimandibles and the patient sample comprised female and male subjects of ages ranging from 18 to 52 years (mean age, 35 years) selected randomly from the database of patients at the Division of Oral Radiology at Piracicaba Dental School State University of Campinas; the anterior loop (AL) of the mental nerve was evaluated regarding the presence or absence, which was classified as rectilinear or curvilinear and measurement of its length was obtained. The observations...

Evaluation and New Classification of Alveolar Bone Dehiscences Using Cone-beam Computed Tomography in vivo International Journal of Morphology
Yang,Yan; Yang,Hui; Pan,Hongyin; Xu,Jue; Hu,Tao.
Alveolar bone dehiscences, which were "V" shaped defects related the margin of the alveolar bone, were common findings in different populations and decreased bony support of teeth. It was difficult to detect dehiscence during direct clinical examination. All of the previous studies on the prevalence of dehiscences were based on dry human skulls. In the current article, we evaluated the prevalence of dehiscences occurring naturally in a Chinese subpopulation, and prepared a classification of dehiscences using cone-beam computed tomography (CBCT). The high prevalence rate of dehiscences and different characteristics of each category suggest that it would be helpful for clinicians who perform periodontal surgery, endodontic surgery, implant surgery or...
