29、and semicircular in cross-section. NOTE 2 Periodontal curettes are subdivided in universal curettes and special curettes. 3.1.2 Gr-type curette designed specifically for the treatment of root surfaces NOTE 1 The fine differentiated shape of the working end allows the treatment of specific areas of t
30、he root surface. NOTE 2 The cutting angle formed between the facial surface and the longitudinal axis of the first shank is approximately 70. The facial surface and the lateral surface are ground to form the cutting edge. 4 DIN EN ISO 13397-2:2013-01 EN ISO 13397-2:2005 + A1:2012 (E) 3.1.3 facial su
