Algorithmically Detecting Brain Abscess Caused by Dental Infection

by

An interesting article titled “Dental focal infection-induced ventricular and spinal canalempyema: A case report” appears in the World Journal of Clinical Cases written by Hang Xue an et al. (vol. 8, no. 14, pp. 3114-3121, July 26, 2020). A discussion is made of a case report of a 53 year old woman who developed a brain abscess caused by a dental infection and how an algorithm pathogenic sequencing technique was used for diagnosis. In the article, the authors discuss the 53 year old woman from China who presented to a hopsital in 2019. She had high blood pressure for 10 years that was not well controlled even though she was taking medication and also had dental cavities for the prior three years. When she arrived at the hospital she was in narcosis and had no autonomous respiration. She had Cerebrospinal … Read more

Wisdom Teeth Removal Leads to Persistent Headache and Viral Encephalitis

by

A person in Scotland had wisdom teeth removed that resulted in an infection. This lead to a persistent headache that was later diagnosed as viral encephalitis but initially missed. The person who had wisdom teeth removed did not have the proper diagnosis made by both oral and maxillofacial surgeons and when admitted to a hopsital, medics from NHS Fife at the Victoria Hospital in Kirkcaldy, Scotland. None of the people who treated the person suspected an infection and the person was not given an MRI scan. This lead to encephalitis which is an inflammation of the brain typically caused by an infection. A complaint was submitted to the Scottish Public Services Ombudsman for this case and they came out with a decison report that contained a summary of the case and recommendations. The board of NHS Fife where the person was … Read more

Wisdom teeth and periodontal damage of second molars

by

An interesting article titled “Third molars and periodontal damage of second molars in the general population,” written by Kindler et al. appears in the Journal of Clinical Periodontology, (vol. 45, pp. 1365-1374, 2018). The article explores the association between impacted or erupted wisdom teeth and periodontal pathology using probing depth and clinical attachment levels. Additional information on periodontal probing depth and a wisdom tooth’s effect on adjacent second molars can be found on the Risks of Keeping Wisdom Teeth page on this website. In previous works impacted wisdom teeth have been identified as a risk factor for developing tumors, dental cysts, and other pathology in adjacent second molars. Even without periodontal symptoms, periodontal damage on the distal aspect of second molars can be present. In the article the authors looked at data from a population-based Study of Health in Pomerania (specifically West Pomerania, … Read more

Dental Age Estimation Using MRI of Wisdom Teeth

by

Recently, three articles have been published on this site regarding using wisdom teeth to estimate age: 1) forensic age estimation using wisdom teeth, 2) using panoramic x-rays of lower wisdom teeth to legally prove if someone is older than 18 years and 21 years , and 3) Using lower wisdom teeth developmental stages determined from panoramic x-rays to calculate age. All such articles use panoramic x-rays of wisdom teeth in order to attempt to estimate the age of the person they came from. However, recently there has also been articles describing using Magnetic Resonance Imaging (MRI) of wisdom teeth to predict age. One article is by Baumann et al. “Dental age estimation of living persons: Comparison of MRI with OPG,” Forensic Science International, vol. 253, pp. 76–80, 2015. Another article is by Guo et al. “Dental age estimation in living individuals using … Read more

Migraine Associated with Changes in Structure of Arteries

by

A recent study by researchers from the Perelman School of Medicine at the University of Pennsylvania has shown the arteries supplying blood flow to the brain is more likely to be incomplete in people who experience migraine. The arterial supply of blood to the brain is protected by numerous connections between the major arteries which is known as the circle of Willis. Those who experience migraine and especially migraine with aura are more likely than those without migraine to be missing some components of the circle of Willis. These structural changes in the circle of Willis are something people are born with. In this study, which appeared in PLOS ONE, the researchers suggest that these structural alterations of the blood supply to the brain may increase susceptibility to changes in cerebral blood flow, which may contribute to abnormal neuronal activity … Read more
