Interappointment emergencies in teeth with necrotic pulps.

Area of Science:

• Endodontics
• Dental Emergencies
• Pulp Biology

Background:

• Interappointment emergencies, commonly known as flare-ups, are a concern during endodontic treatment.
• Understanding the factors influencing the incidence and severity of these emergencies is crucial for patient management.
• Previous research has explored various potential contributing factors to endodontic flare-ups.

Purpose of the Study:

• To evaluate the incidence of interappointment emergencies in teeth with necrotic pulps, comparing symptomatic and asymptomatic cases.
• To quantitatively assess the severity of flare-ups using a standardized flare-up index.
• To identify specific patient or lesion characteristics associated with increased flare-up incidence or severity.

Main Methods:

• A cohort of patients with necrotic pulps undergoing endodontic treatment was prospectively evaluated.
• Interappointment emergencies were recorded and their severity quantified using a validated flare-up index.
• Statistical analysis was performed to compare flare-up incidence across different demographic, clinical, and treatment variables.

Main Results:

• No significant differences in flare-up incidence were found based on gender, age, lesion diameter, analgesic use, or placebo.
• Preoperative diagnosis (symptomatic vs. asymptomatic) did not significantly impact the occurrence of flare-ups.
• A statistically significant higher incidence of painful flare-ups was observed in mandibular teeth compared to maxillary teeth (p < 0.05).

Conclusions:

• The preoperative symptomatic status of a necrotic tooth does not appear to influence the likelihood of an interappointment emergency.
• Factors such as gender, age, and lesion size are not significant predictors of flare-up incidence in this study.
• Mandibular location is a significant factor associated with a higher occurrence of painful endodontic flare-ups.
