English to Portuguese Medical Medical: Dentistry sorriso

Digital video and computer technology enables the clinician to record anterior tooth display during speech and smiling at the equivalent of 30 frames per second. We typically take 5 seconds of video for each patient, yielding 150 frames for comparison. The videos are recorded in standardized fashion with the camera at a fixed distance from the subject. One segment of video is taken in the frontal dimension (Fig 3), and another segment of video is taken from the oblique view. These clips, taken before and after treatment for all patients, allow us to use matched frames to analyze changes in smile characteristics. The patient’s head is placed in a cephalometric head holder to obtain natural head position, and the patient is asked to rehearse the phrase “Chelsea eats cheesecake on the Chesapeake,” and then to smile. The video is downloaded to the computer, and the video clip is compressed. Each clip is approximately 4 MB. The video clip is reviewed, and the frame that best represents the patient’s natural unstrained social smile is selected
