Comparison of GTR, T-PRF and open-flap debridement in the treatment of intrabony defects with endo-perio lesions : a randomized controlled trial
2019
Background Titanium- prepared platelet rich fibrin (T-PRF) is an autologous hemo-component with a high concentration of platelets that also incorporates leukocytes, and growth factors into the dense fibrin matrix and can be used as a healing biomaterial. This study assesses the adjunctive use of T-PRF in intrabony defects (IBDs) with open flap debridement (OFD) in comparison with guided tissue regeneration (GTR) as a gold standard and OFD alone as a control. Material and Methods A total of 45 patients (15 per group) were randomized as either T-PRF (test group), GTR (test group), or OFD alone (control group) sites. Probing depth (PD), clinical attachment level (CAL), and IBD were recorded. T…
Comparison of the detection of periodontal pathogens in bacteraemia after tooth brushing by culture and molecular techniques
2016
Background: The prevalence and amounts of periodontal pathogens detected in bacteraemia samples after tooth brushing-induced by means of four diagnostic technique, three based on culture and one in a molecular-based technique, have been compared in this study. Material and Methods: Blood samples were collected from thirty-six subjects with different periodontal status (17 were healthy, 10 with gingivitis and 9 with periodontitis) at baseline and 2 minutes after tooth brushing. Each sample was analyzed by three culture-based methods [direct anaerobic culturing (DAC), hemo-culture (BACTEC), and lysis-centrifugation (LC)] and one molecular-based technique [quantitative polymerase chain reactio…
Estudio clínico de la asociación entre enfermedad periodontal y obesidad en pacientes con Síndrome de Down
2015
Los pacientes con Síndrome de Down (SD) presentan una serie de características orales y dentales como la macroglosia, alteraciones dentarias en calidad y cantidad, retraso en la erupción, disminución en el número de caries, problemas oclusales y un aumento de la prevalencia de periodontitis. La periodontitis es una enfermedad inflamatoria que afecta a los tejidos de soporte del diente, la encía, el hueso y el ligamento periodontal. Se considera el resultado del desequilibrio entre la interacción inmunológica del huésped y la flora de la placa dental marginal que coloniza el surco gingival. Es una enfermedad de origen multifactorial, originada por las bacterias presentes en la placa bacteria…
Estudio longitudinal de la relación entre presencia de bacterias periodontopatógenas y estado de salud periodontal.
2015
La periodontits crónica en una enfermedad que afecta a los tejidos periodontales y conlleva la destrucción de los mismos. En la cavidad oral se han identificado aproximadamente 500 especies de bacterias, de las cuales 415 están presentes en la placa subgingival pero no todas desempeñan el mismo papel en la etiopatogenia de la periodontitis crónica. A. Actinomycetemcomitans ha sido asociada a periodontitis agresiva, mientras que Porphyromonas gingivalis, A. actinomycetemcomitans, Tannerella forsythia, Treponema denticola y Eikenella corrodens se han asociado con periodontitis crónica. En 1998 Socransky et al, describieron el Complejo Rojo, formado por la asociación de Bacteroides forsythus (…
Periodontal disease associated to systemic genetic disorders
2007
A number of systemic disorders increase patient susceptibility to periodontal disease, which moreover evolves more rapidly and more aggressively. The underlying factors are mainly related to alterations in immune, endocrine and connective tissue status. These alterations are associated with different pathologies and syndromes that generate periodontal disease either as a primary manifestation or by aggravating a pre-existing condition attributable to local factors. This is where the role of bacterial plaque is subject to debate. In the presence of qualitative or quantitative cellular immune alterations, periodontal disease may manifest early on a severe localized or generalized basis - in s…
Prevalence of endodontic infection in patients with Crohn ́s disease and ulcerative colitis
2021
[Background] Previous studies have linked apical periodontitis (AP) to inflammatory bowel disease (IBD). The aim of this study was to compare the prevalence of AP and root canal treatment (RCT) in patients with ulcerative colitis (UC) and Crohn ́s disease (CD).

Evaluación de la capacidad de un nuevo colutorio de inhibir la formación del cálculo dental supragingival
2014
Introducción: El cálculo dental supone un problema para la salud oral ya que incrementa la acumulación de placa y toxinas bacterianas e impide su adecuada eliminación debido a la rugosidad de su superficie favoreciendo de esta manera a la evolución de la enfermedad periodontal. Objetivos: Este trabajo pretende estudiar la magnitud de cálculo formado tras el empleo de un colutorio antisarro a base de pirofosfatos para analizar así su eficacia y los efectos adversos sobre diversos aspectos de la cavidad oral. Material y método: Se realizó un ensayo clínico aleatorizado, cruzado y a doble ciego. Todos los individuos utilizaron un colutorio B (pirofosfatos) y un colutorio A (placebo) con las mi…
Racial disparity and prognosis in patients with mouth and oropharynx cancer in Brazil.
2022
Oral and oropharyngeal cancer (OPC) is an important cause of morbidity and mortality worldwide. Populations in situations of social vulnerability tend to have higher incidences of cancer, a higher proportion of late diagnosis, greater difficulties in accessing health services, and, consequently, worse prognosis. The aim of this study was to evaluate the relationship between race/skin color and OPC prognosis in Brazil. This is a cross-sectional epidemiological study using OPC data from the National Cancer Institute between the years 2000 and 2019. The selected variables were: gender, race/skin color, age, education, smoking and alcohol consumption, stage of the disease and disease status at …
