Objective. Evaluate the levels of inflammatory chemical mediators such as interleukin- 1α(IL-1α), interleukin-1β (IL-1β), tumorosis factor-α (TNF-α) and clinical parameters in patients diagnosed with chronic or aggressive periodontitis, before and after non-surgical periodontal therapy (NSPT). Methods. Crevicular gingival fluid (CGF) samples were taken in 11 patients diagnosed with periodontitis and 11healthy controls for evaluating levels of IL-1α, IL-1β, TNF-α before and after the NSPT, using the ELISA technique (Immunosorbent Assay Linked to enzymes). Results. In the group with periodontitis the decrease of the clinical parameters after the treatment is also observed (p <0.05). In FGC, IL-1β had the highest levels, followed by IL-1α and TNF-α. After NSPT, IL-1β decreased 17 times its concentration and IL-1α 4 times in relation to the initial values, however, only a st...

Objetivo. Evaluar los niveles de mediadores químicos inflamatorios como la interleucina- 1α (IL-1α), interleucina-1β (IL-1β), factor de necrosis tumoral-α (TNF-α) y los parámetros clínicos en pacientes diagnosticados con periodontitis crónica o agresiva, antes y después de la terapia periodontal no quirúrgica (TPNQ). Métodos. Se tomaron muestras de fluido gingival crevicular (FGC) en 11 pacientes diagnosticados con periodontitis y 11 controles sanos para evaluar niveles de IL-1α, IL-1β, TNF-α antes y después de la TPNQ, mediante la técnica de ELISA (Enzyme-Linked Immuno Sorbent Assay). Resultados. En el grupo con periodontitis se observó disminución significativa de los parámetros clínicos después del tratamiento (p<0,05). En FGC, IL-1β presentó los niveles más elevados, seguido de IL-1α y TNF-α. Posterior a la TPNQ, IL-1β disminuyó 17 veces su concentrac...

Objective. Perform human papilomavirus (HPV) detection and typing in the oral cavity in a group of HIV positive patients, treated at the Center for Care of Patients with Infectious Diseases (CAPEI) of the Faculty of Dentistry-Central University of Venezuela. Methods. Thirty-one oral swabs from HIV-positive patients were evaluated to detect HPV infection using the INNO-LiPA Reverse Hybridization System that detects 28 HPV genotypes of high and low oncogenic risk. Results. The 61.0% of the evaluated samples had an HPV infection. The low risk genotype 6 was the most frequent (73.68%), followed by genotypes 18, 11 and 16 with 63.16%, 37.0%, and 32.0%, respectively. Seventy-four percent of HPV positive samples had multiple infections, being the more frequent the mixed coinfection (35.70%), with HPV genotypes 6/18 of low and high oncogenic risk, 21.40% with genotypes 11/6/18 and 6/11, each one...
