A Dutchman dubbed the "dentist of horror" has been sentenced to eight years in jail in France for mutilating the mouths of some 120 patients, reports the BBC.
Jacobus van Nierop, 51, "took pleasure" in causing horrific injuries to patients in the small central town of Château-Chinon, prosecutors said.
He was banned from practising dentistry and fined €10,500 (£8,140; $11,900).
Van Nierop fled to Canada when suspicions arose and strongly fought extradition to France in 2014.
The court in the central French town of Nevers heard that patients had suffered broken jaws, recurrent abscesses and septicaemia from van Nierop's work. He had drugged patients then mutilated them as they slept in his dentist's chair.
Prosecutor Lucile Jaillon-Bru said van Nierop had carried out "useless and painful procedures".
She said his aim had been to earn money through claiming on patients' medical insurance schemes and to take "pleasure at causing pain".
