Teeth Problems are a Result of our Jaws Changing

An interesting article titled “Why We Have So Many Problems with Our Teeth” appeared in Scientific America written by By Peter S. Ungar (paleontologist and dental anthropologist) on April 1, 2020 (322, 4, 44-49). The article discusses how human jaws today are very different than that of our ancestors. In fact today our jaws can be consider underdeveloped due to less chewing that occurs and has kept our teeth from fitting properly into our mouths. The author states ” Nine in 10 people have teeth that are at least slightly misaligned, or maloccluded, and three quarters of us have wisdom teeth that do not have enough room to emerge properly. Simply put, our teeth do not fit in our jaws.” The author says that teeth no longer fit into jaws because human diets have changed over the years to use softer more processed foods … Read more

Cinematic rendering to visualize teeth segmentation

An interesting article titled “Cinematic rendering to improve visualization of supplementary and ectopic teeth using CT datasets” written by Ines Willershausen and et. al. appears in Dentomaxillofacial Radiology in 2023 (no. 51, 20230058). The article discusses cinematic rendering (CR) which is a visualization technique that uses physically based volume rendering to create photorealistic images from Digital Imaging and Communications in Medicine (DICOM) data. Specifically the article attempts to tailor pre-existing CR reconstruction parameters for use in dental imaging to create 3D visualization of ectopic, impacted, and supplementary teeth. This image is from Ines Willershausen and et. al., “Cinematic rendering to improve visualization of supplementary and ectopic teeth using CT datasets,” Dentomaxillofacial Radiology, 2023, no. 51, 20230058 and has a Creative Commons license. 7-year-old girl with a horizontally impacted canine (a) A panoramic radiograph.

Lemierre’s Syndrome After Wisdom Teeth Extraction

One possible complicaton after wisdom teeth extraction is known as Lemierre’s Syndrome. Lemierre’s Syndrome is a rare complication with limited cases being reported that can happen after having wisdom teeth extracted. Since antibiotics have been introduced it is also referred to as “the forgotten disease.” It has been covered on this site before, and is listed as a complication of wisdom teeth removal at http://www.teethremoval.com/complications.html. Lemierre’s Syndrome starts with an infection in the head and neck region and presents with swelling, a high fever, neck pain, and a sore throat. It has a high mortality rate of 18% and thus imaging and antibiotic treatment are of the upmost importance if it presents. Diagnosis involves laboratory results including blood cultures and radiological scans such as CT imaging. Particularly, a CT scan with contrast can identify a thrombosed vein, such as the … Read more

Shared Medical Appointments for Wisdom Teeth Informed Consent

In the past informed consent for wisdom teeth surgery has been discussed on this site, see for example the post Informed Consent in Dentistry: Can Change Impact Personal Injury Cases? Often when it comes to have wisdom teeth surgery patients are shown a video discussing risks and benefits and treatment options related to wisdom teeth, then have an opportunity to discuss with their surgeon and ask any questions, and then sign a document acknowledging that they understand the risks and benefits. Such interaction typically places in a one on one setting with just the patient and the doctor. The patient is of course then billed for this appointment and must either pay out of pocket or pay what is remaining from their insurance plan and after meeting any insurance plan deductibles. There are some ways to possibly decrease the cost … Read more

Incorrect Tooth Extraction Protocol

An interesting article titled “Incorrect tooth extraction – Never say never?” written by McKernon et al. appears in Oral Surgery in 2017 (vol. 10, pp. 30-35). The article discusses development of a protocol for dealing with cases of extracting the wrong tooth. Extracting the wrong wisdom tooth is a possible complication of removal and has occurred before, see http://www.teethremoval.com/complications.html. In the article the authors discuss how checklists are now used during surgery in an attempt to decrease medical errors. Even with these checklists reports of wrong tooth extraction still occur. The authors state that cases of wrong tooth extraction occur about once a week among all dentists in the U.K. The most common reasons for extracting the wrong tooth include cognitive failure and miscommunication. The authors state “We suggest…as human error can never be completely eradicated, a protocol must be … Read more
