ABSTRACT

Introduction: The apical constriction where the pulp is linked to the apical periodontal tissue referred to as the minor diameter is recommended by many as the appropriate landmark where root canal preparation and obturation should terminate. The traditional method used to determine working length (WL) is based on the radiographic visualization of an instrument placed in the canal. These electronic apex locators can be affected by electromagnetic interference by the cell phones radiation. Hence, the present study was conducted to check the effect of cell phone radiation on electronic apex locator.
Aim and Objectives: To evaluate the interference of active cellphones during electronic working length (EWL) determination of a root canal.
Materials and Methods: forty patients requiring root canal treatment in the anterior teeth or premolars having single canal and mature apices were selected for this study. Working length determination was done using no. 15 K‑file. Electronic apex locators Raypex 6 and Root ZX mini were used for working length determination. Cellphones iPhone 6s was evaluated for their interference. The experiment was conducted in a closed room (9 feet × 9 feet). Stability of the readings was also determined for every condition.
Statistical Analysis: The data were statistically analyzed using one‑way ANOVA and paired t‑test at 0.05 level of significance.
Results: Results were not statistically significant.
Conclusion: cellphones do not interfere with the EWL determination under all four experimental conditions.
