A western Pennsylvania dentist was scheduled to see a full slate of 14 patients. There was just one problem, according to police in Butler County, Pa.

The dentist, identified by police as Dr. Gregory Bellotti, later allegedly admitted drinking a bottle of vodka before those patients arrived to his Mars, Pa., office for their dental work.

All this, according to WPXI-TV in Pittsburgh, which reports:

In the end, the dentist, who would later show a blood alcohol level of .418 percent -- more than five times the legal driving limit - ended up working on eight of his 14 patients during the incident earlier this year.

But at some point, the dentist's staff became so concerned about his "altered level of consciousness" they called 911.

Responding police officers said Bellotti appeared to be confused and was unable to do simple tasks or answer questions.

Since then, police charged Bellotti in late July for reckless conduct that placed or may have placed the patients in danger of death.

He also had his dentist's license temporarily suspended.

He faces formal arraignment in early September.
