Cariology: For removing carious dentin For undermining enamel during tissue-saving preparations For the horizontal finishing of outer cavity margins Periodontics: For the removal of calculus from hard to reach areas such as the lower anterior lingual surfaces For the depuration of concave root grooves and furcations Surgery: For the removal of granulation tissue in connection with apical resections, flap operations, or extractions. Design: Round working end and curved cutting edge Shank angulations ease treatments on hard to reach buccal, distal, and lingual surfaces The triple-angled allows for “back action” functions
