A Silver Spring dental assistant convicted of sexually assaulting a 17-year old girl in 2017 was ordered Friday to serve seven years in prison. The rest of the sentence was suspended.

Mervin Alexander Rivas-Chang, 20, of Germantown, was found guilty in May of inappropriately touching the victim, a patient, while she was having surgery at Maryland Oral Surgery Associates on Sept. 1, 2017.

Ramon Korionoff, a spokesman for the state’s attorney’s office, wrote in an email Friday that in addition to Judge John Maloney’s sentence, Rivas-Chang must register as a sex offender for life.

Rivas-Chang faced the possibility of a prison term between 10 and 25 years.

According to court documents, the teen was having her wisdom teeth removed and went to sleep during the procedure. When she woke up, she stated, a blanket was being placed over her and Rivas-Chang sexually abused her.

The girl eventually saw that the man who abused her was wearing blue surgical scrubs. Staff members later confirmed Rivas-Chang was an assistant in the room during the surgery.

Rivas-Chang was found guilty of sex abuse of a minor, second-degree sex offense and third-degree sex offense, following a four-day trial that concluded with five hours of jury deliberations.

Korionoff wrote that the sentence “holds the defendant accountable.”

Defense attorney Stephen Mercer had little to say in a phone interview following the sentencing.

“I can’t comment. I hope you can appreciate that these types of sentencing events are very difficult on everybody. As a policy matter, we have a no press policy with respect to our cases,” he said.
