Technical Quality of Root Fillings Performed by Undergraduate Dental Students in Single-Canal Teeth: A 10-Year Retrospective Study.

Objective: This study assessed the radiographic technical quality of root fillings in single-canal teeth performed over a decade (June 2013 to June 2023) by undergraduate dental students of the Federal University of Campina Grande.

Methods: All teeth underwent chemomechanical preparation using Gates-Glidden drills and hand instrumentation with stainless steel files up to 1 mm short of the root apex. Apical expansion was performed with up to two or three instruments above the initial anatomical apical diameter.

Strategies for partner notification for sexually transmitted infections, including HIV.

Background: Partner notification (PN) is the process whereby sexual partners of an index patient are informed of their exposure to a sexually transmitted infection (STI) and the need to obtain treatment. For the person (index patient) with a curable STI, PN aims to eradicate infection and prevent re-infection. For sexual partners, PN aims to identify and treat undiagnosed STIs.
