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.
