Endodontic postoperative flare-up: An update

Area of Science:

• Dentistry
• Endodontics
• Oral Surgery

Background:

• Endodontic treatment aims to resolve pulpal and periradicular disease through chemical and mechanical cleaning, disinfection, and obturation.
• Inter-appointment flare-ups, characterized by pain and swelling post-root canal procedures, remain a significant clinical challenge for dentists.
• These complications can necessitate emergency unscheduled appointments, impacting patient care and practice workflow.

Purpose of the Study:

• To review the current understanding of the etiology and contributing factors of inter-appointment flare-ups in endodontic treatment.
• To identify key elements that may predispose patients to post-endodontic pain and swelling.
• To provide insights that can aid clinicians in developing preventive strategies.

Main Methods:

• This review synthesizes existing literature on endodontic flare-ups.
• It examines multifactorial causes including mechanical, chemical, and microbial influences.
• Correlations with patient-specific and treatment-related factors are analyzed.

Main Results:

• Flare-ups are multifactorial, influenced by mechanical, chemical, and microbial elements.
• Factors such as patient age, gender, preoperative pain, tooth condition, irrigation methods, visit number, and intracanal medication are correlated with flare-up incidence.
• While some medications can manage pain, definitive preventive protocols are not yet established.

Conclusions:

• A comprehensive understanding of flare-up etiology is crucial for effective prevention.
• Dentists can adapt strategies based on identified risk factors to minimize the occurrence of inter-appointment flare-ups.
• Further research may lead to standardized protocols for preventing post-endodontic complications.
