LGBTQIA+ vs the Brazilian Unified Health System: Basic Health Unit Use and Associated Factors.

The Brazilian Unified Health System provides universal health care access without regard to sexual orientation and gender identity. We conducted a nationwide study with a cross-sectional design and intentional sampling methods to investigate factors associated with Basic Health Unit (BHU) use by the LGBTQIA+ community. Data were collected via a questionnaire available through social networks.

Influence of rotary and reciprocating kinematics on the accuracy of an integrated apex locator.

We evaluated in vitro the influence of nickel-titanium instruments kinematics on the accuracy and variation of root canal working length measurements, performed with an integrated apex locator, at glide path and at the end of shaping. Forty-four mandibular incisors, included in an alginate model, were allocated at random to two groups: reciprocating and rotary. Working length was determined at glide path stage and at the end of shaping.
