This July, at a dental clinic in Sakai City, Osaka, a 17-year-old male scholar attending a particular wants faculty suffered from hypoxia throughout a tooth extraction process below basic anesthesia, and died a few month later.

Police are investigating the circumstances on the time as it’s suspected that the tube that sends oxygen to the lungs could have by chance entered the esophagus.
