ProFile .04 Taper with or without chloroform
seemed to be a viable alternative retreatment technique for guttapercha-obturated root canals.
Sae-Lim V, et al, 2000
The rotary methods were considerably faster in removing gutta-percha from obturated root than the hand methods, and the time for the ProFiles alone was less than that for Profiles with chloroform
Pitt Ford ,etal2001
tamse & kafine 1980 :
zygomatic arch interferes with the apical third of the roots of the first and second upper molars. The number of interferences around the second molar apices was much larger (42 percent average) than those around the first molar apices (20 percent average). For endodontic radiographic diagnosis of the upper two molars, the bisecting-angle technique has proved to be unreliable. Need to shift x-ray beam to move arch off of the root.
when using the bisecting angle technique, superimposition of the zygomatic process of the maxilla over the root apices of molar teeth will occur. Modification of the bisecting angle technique by reducing vertical angulation will decreases the incidence of superimposition of the zygomatic process . Fava & Dummer 1997
Decrease in vertical angle produces cause an elongated tooth and may increase the size of the radiolucent area,Huumonen & Ørstavik 2002
