The trial of Seth Lookhart, the Anchorage dentist accused of dozens of charges ranging Medicaid fraud, reckless endangerment and unlawful dental acts continued Tuesday.

While a video showing Lookhart extracting a tooth from a sedated patient while riding a hoverboard highlights the prosecutions claims of unlawful dental acts, the most serious penalties Lookhart could face if convicted are tied to felony fraud, scheme to defraud and theft charges.

On Tuesday four witnesses called by the prosecution testified. Two were former patients, both of whom were on Medicaid at the time. The other two witnesses were former employees of Lookhart.

The prosecution used the witnesses to try and form a narrative showing that Lookhart intentionally performed unnecessary procedures on Medicaid patients and billed Medicaid higher rates than patients with private insurance.

The defense's questioning of the witnesses attempted to demonstrate that Lookhart's practices were not unusual for the profession and characterized repeated procedures on patients as attempts to provide the best care.

The video of Lookhart operating while riding a hoverboard was not discussed Tuesday.

The trial is scheduled to continue Wednesday morning.
