Objective: The objective of study was to explore the relationship of breathing and pain during endodontic

therapy.

Materials and methods: 500 patients who presented in the department of operative dentistry were included in

the study. Numeric pain scale was used to document the pain perceived during endodontic therapy. Results were

analysed using SPSS version 23.

Results: Among the 500 cases, 250 cases presented with mild pain, 158 presented with moderate pain while 92

presented with severe pain. 55.4% cases were of nasal breathers while 44.6% cases were of oral breathers.

Conclusion: Patients presenting with nasal breathing pattern reported with mild pain perception during

endodontic therapy when compared to patients who were oral breathers. Considering life style modifications like

breathing patterns, body hydration and sleep impact the patient’s life and pain management during endodontic

therapy. Educating patients on proper breathing and its benefits will have positive outcome on endodontic
