Surface treatment of implant materials with antimicrobial nanoparticulates.

This study analyzed nanostructured silver vanadate (AgVO3) films on certain substrate surfaces found in dental implant devices in order to see if these films promote antimicrobial activity. Enamel and glaze vehicles were used to apply the nanomaterial (0.0% [control], 2.

Effect of highly active antiretroviral therapy use on oral manifestations in pediatric patients infected with HIV.

Aims: The aim was to assess the prevalence of oral lesions in HIV-infected children undergoing highly active anti-retroviral therapy (HAART), and the association between the duration of HAART usage and oral lesions.

Subjects And Methods: Totally, 111 medical and dental records of HIV-infected children, aged from 2 to 16 years old were reviewed for medical data, presence of oral lesions, and caries prevalence. According to the type of medication, the children were grouped as follows: 51 were under HAART (G1), 46 were using anti-retroviral medication (G2), and 14 were using no medication (G3).

Influence of the ultimate torsion on the geometry of dental implants.

This study evaluated the profile of implants subjected to torsion test. Four types of implants (Conexão®) were analyzed: Master Porous (MP - external hexagon, cylindrical, double-porous surface implants; 11.5 X 3.

Analysis of primary stability of dental implants inserted in different substrates using the pullout test and insertion torque.

The aim of the study was to evaluate mechanical behavior of implants inserted in three substrates, by measuring the pullout strength and the relative stiffness. 32 implants (Master Porous-Conexao, cylindrical, external hexagon, and surface treatment) were divided into 4 groups (n = 8): pig rib bone, polyurethane Synbone, polyurethane Nacional 40 PCF, and pinus wood. Implants were installed with the exact distance of 5 mm of another implant.
