Clinical and microbiological assessment in a subpopulation of young Argentine patients with severe periodontitis.

Unlabelled: Aggressive periodontitis (AP) is the most serious entity of periodontal disease (stage III/IV, grade C periodontitis according to the latest classification, 2017).

Aim: to enhance knowledge of periodontal microbiota in AP in native Argentine patients and describe the effect of a combined pharmacologicalmechanical periodontal treatment on clinical and microbiological parameters.

Materials And Method: The study analyzed 42 periodontal sites in 11 patients diagnosed with AP.

Microbiological study of the subgingival biofilm in HIV+/HAART patients at a specialized dental service.

The aim of this study was to describe the microbiological profile of HIV patients under highly active antiretroviral treatment (HAART). This crosssectional study comprised 32 HIV patients with periodontal disease (PD) who had been under HAART for more than 6 months. Information about the patients' medical history was obtained from clinical records.

Endodontic microorganism susceptibility by direct contact test.

The aim of this study was to evaluate in vitro the duration of the antimicrobial effect of endodontic sealers by means of the Direct Contact Test. The sealers tested were: Endomethasone - Septodont, Endomethasone C-Septodont, Endion-Voco, Diaket-ESPE, Pulp Canal Sealer-SybronEndo, and AH26-Dentsply DeTrey. The endodontopathic microorganisms (MO) confronted were: Staphylococcus aureus (Sa), Candida albicans (Ca), Enterococcus faecalis (Ef), Prevotella intermedia (Pi), Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn).

Antimicrobial effect in vitro of chlorhexidine and calcium hydroxide impregnated gutta-percha points.

Unlabelled: The aim of this study was to evaluate the antimicrobial activity of points containing antiseptics used for temporary obturation in endodontics. Points containing calcium hydroxide (Roeko and Hygienic), and chlorhexidine (Roeko) were tested and gutta-percha points served as control (Meta Dental Corp.).
