Abstract:
We report the case of a patient presenting with severe headache and progressive aphasia due to a large brain abscess. End-stage peri-implantitis on a dental implant in the upper jaw with contact to the maxillary sinus floor causing maxillary and frontal sinusitis could be identified as the source of infection. Multidisciplinary treatment included broad-spectrum antibiotics, craniotomy for abscess drainage, sinus surgery, and the removal of the implant. Despite all the care taken, the patient died, underlining the importance of oral hygiene and a frequent recall in patients with dental implants. To the best of our knowledge, this is the first report of a brain abscess caused by peri-implantitis in the literature.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
