LA Times said:
VACAVILLE, Calif. — His jaw clenched beneath a blue surgeon's mask, Opanin Gyaami jerks his right arm and pulls out a prize: the decayed tooth of patient Larry Butler, also known as state prison inmate J22312
By the time he is done, Gyaami's smock and mask are spotted with the inmate's blood. He gently pats Butler on the shoulder and wishes him well.
The 71-year-old dentist reports to the state prison in Vacaville day after day, long past retirement age. He wishes he could have hung up his drill and forceps years ago, but he's still paying off a student loan.
