(ANCHORAGE, Alaska) — An Alaska dentist accused of fraud and unnecessarily sedating patients also performed a procedure while riding a wheeled, motorized vehicle known as a hoverboard, authorities said. Prosecutors charged 34-year-old Seth Lookhart with felony Medicaid fraud and reckless endangerment. A former patient testified Wednesday at his trial that she was angered when an investigator showed her an unauthorized 2016 video of Lookhart extracting one of her teeth while she was sedated and he was riding the hoverboard.
