Introduction: This randomized clinical study compared the antibacterial effectiveness of treatment protocols using either a triple antibiotic solution (1 mg/mL) or calcium hydroxide/chlorhexidine paste as interappointment medication in infected canals of teeth with primary apical periodontitis.
Methods: The root canals of single-rooted teeth with apical periodontitis were prepared by using a reciprocating single-instrument technique with 2.5% sodium hypochlorite irrigation and then medicated for 1 week with either a triple antibiotic solution (minocycline, metronidazole, and ciprofloxacin) at 1 mg/mL (n = 24) or a calcium hydroxide paste in 2% chlorhexidine gluconate (n = 23).
Introduction: This study investigated the association of CD14 -260C>T and TLR4 +896A>G gene polymorphisms with post-treatment apical periodontitis in Brazilian individuals.
Methods: The study population consisted of 41 patients with post-treatment apical periodontitis and 42 individuals with root canal-treated teeth exhibiting healed/healing periradicular tissues (controls). All teeth had apical periodontitis lesions at the time of treatment, which was completed at least 1 year previously.
Introduction: Polymorphisms of genes encoding leukocyte surface receptors for the constant region of immunoglobulin G (FcγR) might influence the host response to infection and consequently affect the outcome of the endodontic treatment. This study investigated the association of FcγRIIIa gene (FcγRIIIA) polymorphism with post-treatment apical periodontitis in Brazilian subjects.
Methods: The study population consisted of 26 patients with post-treatment apical periodontitis and 43 subjects with root canal-treated teeth exhibiting healthy/healing periradicular tissues (controls).

Objective: Herpesvirus infection can cause immunosuppression and then act as a modifier of apical periodontitis, influencing the disease severity and response to treatment. The purpose of this study was to investigate if herpesvirus infection, as inferred by salivary carriage, may influence the endodontic treatment outcome.
Study Design: The study population included 72 patients who had root canals treated more than 1 year previously because of necrotic pulps and apical periodontitis.
