title: Differential Diagnosis and Treatment Proposal for Acute Endodontic Infection.
abstract: The objective of this study was to describe the main lesions that simulate clinically and propose a treatment protocol for acute endodontic infection. Signs and clinical symptoms of periodontal abscess, gingival abscess, odontoma, herpes simplex, pericoronitis, acute pulpitis and necrotizing ulcerative gingivitis/periodontitis (NUG/NUP) were described and compared with acute endodontic infections. A treatment protocol was described by optimizing the procedures in access cavity, microbial decontamination and detoxification of the root canal, apical debridement, intracanal and systemic medication and surgical drainage procedures. The convenience of the use of 5.25% sodium hypochlorite, root canal instrumentation using a crown-down technique, intracanal medication with 2% chlorhexidine or triple antibiotic paste and the convenience of the use of antibiotics, analgesics, and surgical drainage to solve cases of acute dentoalveolar abscess was discussed.
