For each groups, correlation between coronal movement of thePTG and AF was investigated by using reference points of root apex of primarytooth, AF and crown apex of the PTG.Results: InGroup 2, where the PTG was located at the apical third of the roots of primarytooth, the correlation was found between the coronal movement of the PTG and AF.However, this correlation was not found in Group 1 and 3, where the PTG was atbelow the roots of primary molar and middle third, respectively.Conclusion: Itwas concluded that the crown apex of the PTG could be used as a reference pointin determining the canal working lenght in the case where the PTG was locatedin the apical third.
