Enamel Composition May Help Predict Tooth Health

An interesting article titled “Mesoscale structural gradients in human tooth enamel” appears in the Proceedings of the National Academy of Sciences written by Robert Free and et. al. (vol. 119, no. 52, pp. e2211285119, December 19, 2022). The article explores the hierarchical architecture of human enamel which is integral to the function of human teeth. In the article, discussion is made of how tooth decay has lead to many dental visits due to cavities. There is not much known about how or why many people experience tooth enamel decay or congenital conditions. In the article, the authors used synchrotron X-ray diffraction at submicrometer resolution technology, to observe tiny differences on the order of picometers in the crystallographic parameters of enamel crystallites, which they linked to the presence of ions such as magnesium and sodium or carbonate. Features of enamel at length scales smaller … Read more

Using the sedative Remimazolam for oral surgery

An interesting article titled “Can Remimazolam Be a New Sedative Option for Outpatients Undergoing Ambulatory Oral and Maxillofacial Surgery?” appears in the Journal of Oral and Maxillofacial Surgery written by Zijian Guo and et. al. (Available online 16 September 2022). The article discusses the sedative remimazolam and its possibility to sedate in oral surgery as effectively as midazolam. In the article the authors discuss how patients can receive dental treatment with more comfort using sedation. Midazolam is widely used in oral and maxillofacial surgery but has side effects of increased accumulation and respiratory depression. Remimazolam has similar pharmacological effects to midazolam but has rapid onset, fast metabolism, less potential adverse effects. Remimazolam has a a mean half-life of between 0.5 and two minutes and a terminal half-life in plasma of 37 to 53 minutes.  The authors conducted the first ever … Read more

World record set by nine year old’s wisdom tooth extraction

Recently, a nine year old in Virginia has become the youngest person according to Guinness World Records to have a wisdom tooth extracted. The nine year old boy was 9 years and 327 days old when he had the wisdom tooth extracted. The boy learned that he needed the extraction when his orthondontist in Virginia noticed on a 3D x-ray that he had a wisdom tooth and a molar growing on top of each other. This was in the upper left area of his mouth. The boy said he could not feel the tooth growing but his orthodontist wanted it removed so that the molar could drop in his mouth properly. The boy was referred to an oral surgeon in Virginia. The oral surgeon confirmed wha the orthondotist had said, the wisdom tooth needed to be removed in order to … Read more

Dentists Find Additional Bacteria Species Involved with Tooth Decay

An interesting article titled “Selenomonas sputigena acts as a pathobiont mediating spatial structure and biofilm virulence in early childhood caries,” written by Hunyong Cho and et. al. appears in Nature Communications (vol. 14, no. 1, 2023). The article seeks to study if other bacteria besides Streptococcus mutans are involved with tooth decay and cavities in children, also known as dental caries. Prior to the study it was believed that S. mutans and other acid-making bacteria are adequately removed by teeth-brushing and oral care, and this creates a protective biofilm, or plaque, on teeth. If the plaque is left in place for too long, bacteria consumes sugars from food and drinks and coverts them to acidsm which erode the enamel of affected teeth, in time creating cavities. The article investigated the role of Selenomonas sputigena (S. sputigena) in early cavities in children. S. … Read more

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
