ABSTRACT

Objective: The aim of this study is to compare the mean time of postoperative pain dissipation between working length measurement methods by using an electronic apex locator and digital radiography

Study Design: Randomized clinical trial

Place and Duration of Study: Study was conducted at Punjab Dental Hospital, Lahore for duration of one year, from 1st June 2019 to 30th May 2020.

Patients and Methods: Eighty patients fulfilling the selection criteria were selected. Patient’s detailed demographics age, gender and tooth being treated was recorded. Patients were divided into two groups. Thorough medical and dental history of each patient was recorded and pulpal and periapical status of the tooth to be treated was evaluated with the help of periapical radiograph, periodontal probing, palpation, percussion, electric pulp tester and thermal tests.

Results: Among 80 patients, those having age 14–37 years, mean time (hours) of postoperative pain dissipation between working length measurement methods by using an electronic apex locator and digital radiography was 18.97±19.63 and 21.02+5.53 respectively which was statistically not significant. In male patients, mean time (hours) of postoperative pain dissipation between working length measurement methods by using an electronic apex locator and digital radiography was 27.11±08.14 and 26.34±6.55 respectively which was statistically not significant (p-value 0.431).

Conclusion: There was no difference among mean post-operative pain dissipation time by taking working length from electronic apex locater and digital radiography
