Benva Lazar, 56, was arrested Aug. 10 after a 14-year-old girl told police he had fondled her breasts when she was 13, authorities said.

The arrest came three months after Lazar entered no-contest pleas to six misdemeanor counts of battery for groping adult patients in his care. He has not been sentenced.

Lazar was arrested in October after a 23-year-old patient said he had touched her breasts under the guise that he was screening her for cancer.

Lazar, a married father of two children, specializes in operative and restorative dentistry and has taught at Boston University and Harvard University, according to his Web site.
