Anthony Richardson, a 49 year old Bronx dentist who has been charged in four rape cases, copped a plea to the latest charges yesterday and was freed after spending nearly three years in jail awaiting trial.  Richardson pleaded guilty to sexual misconduct and endangering the welfare of a child.  He allegedly placed a gas mask over the girl's face at his apartment, knocking her out, and had sex with her.  In 1995, he beat charges of raping a 16 year old girl under anesthetic in his Grand Concourse office.  He also faced similar charges in 1987 and 1989, winning acquittals in both cases.
