Cinematic and Volume Rendering of the Facial Skeleton CT can aid Visualization

An interesting article titled “Three-dimensional perception of cinematic rendering versus conventional volume rendering using CT and CBCT data of the facial skeleton,” written by Tobias Steffen and et al. appears in the April 2022 edition of the Annals of Anatomy (151905). The article sought to explore if three-dimensional cinematic rendering image re-constructions offer advantages over conventional volume rendering to visualize cone beam computed tomography (CBCT) and computed tomography (CT) images of the facial skeleton. In the study, ten dentists reviewed 10 different patient cases of CT or CBCT exams of reconstructed cinematic rendering or volume rendering of the orofacial skeleton. The dentists were given a questionnaire to assess objective and subjective criteria of image perception. To assess objective criteria, predefined questions on the visual perception of anatomical image characteristics, were given to the denists. To assess subjective criteria, a visual … Read more

What Dentists Should Say to Patients when Something Doesn’t Go Right

Unfortunately dentists and oral surgeons don’t always have all procedures go as planned for their patients. For example, when it comes to wisdom tooth surgery, it is possible for the wrong set of wisdom teeth to be removed as is discussed on the wisdom teeth complications page, see https://www.teethremoval.com/complications.html. Since procedures don’t always go as planned, on this site before guidance for patients who want to be very defensive has been provided, see the post The Defensive Patients Guide to Wisdom Teeth Removal. While patients can sometimes be bad actors and deny that certain information was provided to them prior to a procedure (see the post Patient Recall During Informed Consent for Wisdom Teeth Surgery), dentists and oral surgeons also can behavior badly such as by telling patient’s after their procedure that their condition that resulted could not have possibly … Read more

Horizontally Impacted Wisdom Teeth on Both Sides

An interesting article titled “Impacted Third Molars, A Rare Occurrence of Identical Bilateral Impacted Mandibular Third Molars in Linguo-Buccal Location: A Case Report” written by Shaul Hameed Kolarkodi and et al. appears in Cureus (vol. 13, no. 12, e20858). The article describes the case of a 20 year old man who had bilateral horizontally impacted lower wisdom teeth which found on a panoramic radiograph and also later confirmed with cone beam computed tomography (CBCT) imaging. In the article the authors described how impacted wisdom teeth are when they cannot erupt into the proper position. They mention how doctors encounter many types of impaction of wisdom teeth teeth and mention how having horizontally impacted lower wisdom teeth on both sides is rare. Impacted wisdom teeth can happen due to a lack of space or a pathological change that can disrupt the … Read more

Illinois Man Dies From Too Much Anesthesia While Having Teeth Extracted

A 51 year old man from Illinois died after having five teeth extacted in July 2021. He had has teeth extracted by an oral surgeon in Lake County which is North of Chicago. During the procedure he was given as given a single dose of 200 milligrams propofol. There was no anesthesiologist present and the oral surgeon was the one also administrating the anesthesia. During the tooth extractions, the man stopped breathing and went into cardiac arrest. Emergency responders were called and when they arrived took the man to a hospital where he died the next day. According to statements from the Lake County Coroner there was too high of a dose of propofol given and this dose would cause a person to not breathe. Further, the oral surgeon did not supply supplemental oxygen until the tooth extractions were already … Read more

Does a Parasite in the Mouth Contribute to Periodontitis?

An interesting article titled “Entamoeba gingivalis Causes Oral Inflammation and Tissue Destruction,” appears in the Journal of Dental Research written by X. Bao and et al. (vol. 99, no. 5, pp. 561–567, 2020). The article seeks to explore the protozoan Entamoeba gingivalis (E. gingivalis) in inflamed periodontal pockets. In the article, the authors sought to validate the frequency of the Entamoeba gingivalis by analyzing the gums of 158 people with periodontitis and healthy controls using polymerase chain reaction and microscopy tests. A total of 107 of the people in the study were healthy controls while 51 had periodontitis. For those healthy control patients, E. gingivalis was detected in oral cavities in 15% of these patients. For those with periodontitis, E. gingivalis was detected in 77% of inflamed periodontal sites and 22% of healthy sites. The authors state “In conjunction with abundant … Read more
