Selective endodontic retreatment of mandibular molar with apical periodontitis ...

Objective: This paper aims to report a clinical case diagnosed with asymptomatic apical periodontitis at the clinic of the Specialization Course in Endodontics at Universidade São Paulo, addressing the indications and techniques performed, as well as clinical and radiographic aspects. Indications for selective retreatment include cases in which the treatment was carried out for more than 1 year, teeth with sati...

Penetration of bioceramic and epoxy-resin endodontic cements into lateral canals

The aim of the present study was to assess the penetration capacity of two endodontic cements, Endosequence BC Sealer and AH Plus, in artificial lateral canals. Twenty-six two-rooted, maxillary first premolars were instrumented to size 40.06 using K3 files. In each root, six lateral canals of two diameters (0.06 and 0.10 mm) were created with a working length of 2, 4, and 6 mm. The specimens were randomly divid...

The objective of the present study was to assess the effectiveness of reciprocating instrumentation in disinfecting oval-shaped root canals infected with Enterococcus faecalis. Forty-five human lower premolars were infected with a culture of E. faecalis (ATCC 29212) for 28 days. Five other teeth that were neither contaminated nor instrumented were used as controls. The 45 specimens were divided into three exper...
