Abstract

The present invention discloses a pediatric endodontic rotary file, which comprises: a cutting region (2), shank region (6) having a shear region, (7) and a head region above shank region. Cutting region (2) comprises a cervical region (5) and upper region (4). The cervical region is provided with 4% taper for about 7mm to form cervical enlargement (22) which facilitates to fill the apical level (31) comfortably in the prepared root canal space (18). The upper region (4) of 7mm has 2% taper inclusive of, apical region (4a) of at least 4.6 mm, which comprises safe end tip (1), to avoid perforations (21) occurring in the middle level (32) of the root canals (12) in primary teeth (A). The shear region (7) facilitates the file to break above the orifice of the root canal and prevents the apical region (4a) from becoming irreversibly embedded in primary tooth (A) after file breakage.
