Abstract

Objectives

The aims of this study were to report the prevalence of inter-appointment flare-ups following adequate root canal disinfection and to investigate the host factors contributing to its occurrence.

Materials and methods

One thousand five hundred patient records were reviewed and the prevalence of flare-up was recorded. Patients’ root canal space status (vital, non-vital or retreatment), medical condition and demographics (age, gender, tooth type and position) were recorded from their dental records. Statistical analyses were performed to determine the impact of the recorded factors on flare-up occurrence.

Results

Nine hundred fifty-one patient records met the inclusion criteria. The prevalence of flare-up was 2.3 %. There was a correlation between the canal space status and patient’s age with flare-up development (P < 0.05). There was no association between flare-up occurrence and tooth type, location, gender or medical condition (P > 0.5).

Conclusion

The root canal space status was the primary factor affecting flare-up occurrence. Patients >50 years had the highest risk in developing flare-ups.

Clinical relevance

This article provides evidence that patients suffering from inflamed pulp will not develop flare-up if adequate cleaning and shaping of the root canal space was performed. It also shows that patients above the age of 50 are a high-risk group that is prone to flare-up development.
