RESUMEN
AIM: To identify Pseudomonas aeruginosa and Staphylococcus aureus in oral biofilms of intubated and non-intubated patients admitted to an Intensive Care Unit (ICU). METHODS: This was a cross-sectional study, with 30 biofilm sites sampled. S. aureus and P. aeruginosa were identified by conventional biochemical assays. Antimicrobial susceptibility was tested by disk-diffusion. RESULTS: Of 30 sites, 50% contained P. aeruginosa and 3.33% S. aureus. P. aeruginosa was detected in similar amounts in all 3 sample sites, with 5 colonized sites (50%). S. aureus colonized a single supragingival site (3.33%). There was resistance to multiple antimicrobial agents of P. aeruginosa in 7 sites (100%) and S. aureus in 1 (100%). CONCLUSIONS: This study revealed an important relationship between P. aeruginosa and S. aureus colonization at supragingival, subgingival and lingual sites and intubation, thus revealing antimicrobial resistant bacteria colonization of medical interest, which may contribute to the therapy choice directed to these microorganisms.

Our study aimed to study the efficacy of ILIB on periodontal parameters and glycemic control in patients with periodontitis and type II diabetes. Twenty-one patients in a randomized clinical trial were divided into 2 groups: control group (CG), conventional periodontal therapy, and test group (TG), conventional periodontal treatment associated with 10 laser applications by the ILIB-Modified (ILIB-M) technique. Fasting blood glucose levels and glycated hemoglobin (HbA1c), visible plaque index (VPI), gingival bleeding index (GBI), and periodontal clinical parameters were evaluated at baseline and after 4 months (T4). Regarding periodontal parameters, the intragroup analysis showed a statistically significant reduction (p < 0.05) between baseline and T4, for the VPI, GBI, BOP, PD, and CAL indexes. However, in the intergroup analysis, no statistically significant improvements (p > 0.05) were observed between the TG and CG for the VPI, GBI, BOP, PD, and CAL indexes. Regarding HbA1C and fasting blood glucose values, no statistically significant improvements were observed in intergroup and intragroup analyses (p > 0.05). The Modified ILIB did not improve the periodontal clinical parameters and glycemic control in patients with type II diabetes.
