Surface energy and wettability of polymers light-cured by two different systems.

Objective: This study evaluated the surface energy and wettability of composite resins polymerized by different light-curing units to ascertain the good wetting of tooth surfaces to achieve adhesion.

Material And Method: Filtek Z350 (3M ESPE), Admira (VOCO) and Grandio (VOCO) resins were selected for the testing procedures. The resins were light cured using LED and Halogen devices.

[Reflections on the education of health professionals].

The objective of the present article is primordially to rise controversies about the education as a whole and the scientific knowledge as important foundations in the academic formation. Believing that the incessant search of the masters degree courses should not limit to the theories as a mere academic education. The methodological dynamics of the knowledge is questioned, as well as truth and knowledge.

[Oral infection control in hospitalized patients: an approach to cardiologist and intensive care units doctors].

This paper aims to find the current level of periodontal med-care knowledge, as well as the possible existence of some oral infection control protocol regarding hospitalized patients. Our sample gathered 110 cardiologists and intensive care units doctors selected from medical teams of five Rio de Janeiro hospitals. Preliminary numbers: 75.

[Evaluating the existence of oral infection control in patients admitted in state hospitals in Rio de Janeiro].

The aim of the present study is to ascertain whether an oral infection control protocol is being used in Rio de Janeiro State hospitals. Sixty two hospitals, both public and private have been surveyed. When asked whether any procedure was being adopted with admitted patients (in case of ICU patients), 39% of the hospitals responded positively.

Wettability of some packable resin-based composites. An in vitro study.

The purpose of this research was to measure the contact angles of some packable resin-based composites in order to determine their wettability related to the surface energy. Materials were manipulated according to the manufacturer's instructions and were inserted in a circular metallic matrix and photo cured for 40 seconds on both sides. The specimens were removed and finished with silicon carbide metallurgical finishing paper (800 gifts).
