¶1. Brian C. Painter, D.D.S., appeals from a circuit court order affirming a decision of the Dentistry Examining Board. The Board determined that Painter, a dentist, engaged in unprofessional conduct on two occasions in violation of Wis. Stat. § 453.07 (2001-02)*fn1 and Wis. Admin. Code § DE 5.02(5) by treating dental caries on minor patients without informing their parents of the viable options for the administration of anesthesia.*fn2 Painter contends that the Board's decision was based on insufficient evidence and an erroneous interpretation of the law. We conclude that the Board's interpretation of § DE 5.02(5) is reasonable and that there is substantial evidence to support its conclusion that Painter engaged in unprofessional conduct. We therefore affirm the circuit court's order upholding the Board's decision.
