BACKGROUND The relationship between impacted mandibular third molar and mandibular canal is important for removal of this tooth. Panoramic radiography is one of the commonly used diagnostic tools for evaluating the relationship of these two structures. OBJECTIVES To evaluate the accuracy of panoramic radiographic findings in predicting direct contact between mandibular canal and impacted thir...

INTRODUCTION This in vivo study assessed accuracy and reliability of tooth length measurements obtained from conventional panoramic radiographs and CBCT panoramic reconstructions to that of a digital caliper (gold standard). METHODS The sample consisted of subjects who had CBCT and conventional panoramic radiographic imaging and who required maxillary premolar extraction for routine orthodont...

Background and Aims: Overlapping of the proximal surfaces of posterior teeth in the panoramic radiography is a major concern. Therefore, an option has been developed in the panoramic unit of Planmeca Promax, namely improved interproximal mode. This mode causes lower horizental angle with the teeth contact region during the unit rotation decreasing overlapping of the panoramic images of the post...

Given panoramic video taken along a self-intersecting path, we present a method for detecting the intersection points. This allows “virtual tours” to be synthesized by splicing the panoramic video at the intersection points. Spatial intersections are detected by finding the bestmatching panoramic images from a number of nearby candidates. Each panoramic image is segmented into horizontal strips...

In this paper, we propose an image rectification method to generate panoramic views from stereoscopic images. Due to different intrinsic and extrinsic characteristics of stereoscopic cameras, there are some mismatches in the vertical direction of the stereo images and they become major obstacles to make a panoramic image. Therefore, we need to reduce mismatches to generate more natural panorami...

AIM To compare digital panoramic images acquired for the presurgical assessment of third molars captured with a storage phosphor-based system with conventional film panoramic radiographs. METHODS AND MATERIALS A total of 51 pairs of digital and conventional panoramic images, made simultaneously, were included in this study. The images were evaluated for diagnostic quality prior to third molar...

The panorama-based annotation method described in this paper uses a panoramic image as the source of information about the positions of the annotations. It nds image alignment parameters between an input frame and the panoramic image and then maps the positions of annotations from the panoramic image to the input frame and displays the input frame overlaid with those annotations. Camera movemen...
