Abstract

Background: Most of root canal preparation use step back technique which form the root canal. The
cool lateral condensation technique is a standard technique taught to students, which has the highest
cure rate between 87% - 94% and a root canal filling was ended by 0-2 mm from the radiographic apex,
which the underfilling cure rate between 68% - 77% and the overfilling cure rate between 75% -76%.
Some research suggests that the molars teeth had the highest frequency of failure in root canal filling.
Objective: To identify the frequency of failure in root canal filling with preparation step back techniques
on a double-rooted teeth Dental Hospital of the University of Jember from 2011 until 2016. Methods: The
design of this study is a descriptive by gathering medical records. The radiograph pictures of doublerooted
teeth which underfilling and overfilling were evaluated by researcher, data was calculated with
manual furthermore data was displayed in tables and graphics. Results and Conclusions: Teeth with
underfilling of 68 teeth larger than teeth that overfilled a total of 18 teeth. The maxillary teeth with the
most underfilling are the teeth 14 and the tooth mandibular 46 where as the most overfilled teeth in the
maxilla are the teeth 26 and the mandibular is the tooth 46. The percentage of root canal treatment
underfilling and overfilling is 27.3% Overall number of patients with multiple root canal treatment.
