Abstract
Introduction The outcomes of oral health conditions and therapy for those conditions are described
by the term “oral health-related quality of life.” Oral health-related quality of
life is recognized by the World Health Organization as an important part of the Global
Oral Health Program. The study aims to compare the impact of three root canal preparation
systems on patients’ quality of life and correlate postoperative pain with the impact
on the quality of life.
Materials and Methods A survey was performed in which 90 patients were randomly assigned to three groups
based on the root canal preparation system: (1) ProTaper Gold (Dentsply, Tulsa Dental
Specialties, Tulsa, Oklahoma, United States), (2) Neoendo flex (Neoendo, India),
and (3) Hyflex EDM/CM (Coltene Whaledent) that included 30 participants in each group.
Data collection included the implementation of a demographic data questionnaire, Oral
Health Impact Profile 14 (quality of life), and visual analogue scale(pain). The questionnaire
was given after root canal treatment in the first 24 hours. The data obtained were
statistically analyzed.
Results No significant differences were found in the quality of life among study groups.
Group 1 demonstrated a highly significant difference in the postoperative pain with
p value of 2.67.
Conclusion Within the limitations of the present study, Protaper Gold showed a highly significant
difference in postoperative pain when compared with other file systems. No significant
differences were found in the quality of life among the study groups.
