2018年9月26日 · Coronoid notch: Also known as sigmoid notch, is a radiolucent concavity located distal to the coronoid process on the superior border of the ramus. Coronoid process: It is a triangular shaped radiopacity seen as extension of the anterior border of the mandible.

2024年5月21日 · This study aims to determine whether and how the data of the medial sigmoid depression (MSD) area via cone beam computed tomography (CBCT) differs from panoramic radiography. This study also...

2021年4月17日 · On a dental panoramic radiograph, the medial sigmoid depression may present as a radiolucent lesion inferior to the sigmoid notch that may or may not be connected to the latter (Figure 1 A). The radiolucency is caused by reduced absorption of radiation due to the thinning of the bone on the lingual side of the sigmoid notch [ 5 ] ( Figure 1 B,C).

2024年5月21日 · This study aims to determine whether and how the data of the medial sigmoid depression (MSD) area via cone beam computed tomography (CBCT) differs from panoramic radiography. This study also aims to evaluate various sigmoid notch types and assess the relationship between sigmoid depression and notch morphology.

2016年6月1日 · The results elucidated in our study suggest that various shapes of the coronoid process, condyle and sigmoid notch depicted by means of panoramic images can thus be used as a quite easier and quicker method for identification of an individual especially in cases of mass disasters, provided when the ante-mortem records are preserved.

Several structures are superimposed on this radiograph. In addition, the ghost images create another layer of complexity. Since panoramic radiography is a frequent imaging technique in the dental office, every dental student must exert sufficient efforts to understand the anatomy.

In both panoramic and CBCT, we found a high and similar prevalence of MSD. While the MSD prevalence was 66.7% for CBCT, it was 58.1% for panoramic. The shape or prevalence of MSDs in either...

In the present study, we accessed the morphological parameters of the shape of condyle, coronoid, and the intervening sigmoid notch as evolutionary markers to establish its efficiency in individual identification. Five hundred radiographs of panoramic view were obtained from the Department of Oral Medicine and Radiology.

1983年6月1日 · Bilateral medial sigmoid depressions in upper ramus region on panoramic film of skull and mandible. This pseudoforamen corresponds to a marked depression which was seen in some specimens in the medial aspect of the upper ramus just below and anterior to the most inferior aspect of the sigmoid notch.

In a panoramic image, different shapes of the coronoid process, condyle and sigmoid notch can often be appreciated and thus this radiographic data when available as ante mortem records and correlated with the post-mortem records can thereby aid in the identification of a …
