A multicenter study of oral health behavior among adult subjects from three South American cities
(2018)The aims of this study were to describe the self-reported oral hygiene habits, dental visit frequency, and gingival bleeding perception in adult populations from three South American cities, and also to assess the ... -
Apoptosis in chronic adult periodontitis analyzed by in situ DNA breaks, electron microscopy, and immunohistochemistry
(American Academy of Periodontology, 2001-04)Background: Apoptosis is an evolutionary form of physiological cell death. Previous studies suggest that apoptosis is involved in the pathogenesis of periodontal diseases. Therefore, we studied the apoptotic events in the ... -
Asociación de mayores niveles de RANKL y linfocitos T CD4+ en periodontitis
(Escuela de Odontología. Facultad de Salud. Universidad del Valle, 2004)Propósito: La periodontitis es una enfermedad infecciosa que involucra una sobre-respuesta inmune del hospedero y se caracteriza por la destrucción de los tejidos de soporte del diente.Durante su desarrollo se establece ... -
Associations Between Matrix Metalloproteinase-8 and -14 and Myeloperoxidase in Gingival Crevicular Fluid From Subjects With Progressive Chronic Periodontitis: A Longitudinal Study
(American Academy of Periodontology, 2010-11)Background: Matrix metalloproteinase (MMP)-8 is a central mediator in chronic periodontitis. MMP-8 can be activated by the cooperative action of otherMMPs such asMMP-14, reactive oxygen species, andmicrobial proteases. ... -
Associations between matrix metalloproteinase-8 and-14 and myeloperoxidase in gingival crevicular fluid from subjects with progressive chronic periodontitis: A longitudinal study
(2010)Background: Matrix metalloproteinase (MMP)-8 is a central mediator in chronic periodontitis. MMP-8 can be activated by the cooperative action of other MMPs such as MMP-14, reactive oxygen species, and microbial proteases. ... -
Changes in lipopolysaccharide profile of Porphyromonas gingivalis clinical isolates correlate with changes in colony morphology and polymyxin B resistance
(Elsevier, 2015)Virulence factors on the surface of Porphyromonas gingivalis constitute the first line of interaction with host cells and contribute to immune modulation and periodontitis progression. In order to characterize surface ... -
Characterization of cellular infiltrate, detection of chemokine receptor CCR5 and interleukin-8 and RANTES chemokines in adult periodontitis
(Munksgaard, 2001-06)Leukocyte migration is essential for immune surveillance of tissues by focusing immune cells to sites of antigenic challenge. The control of leukocyte migration depends on the combined actions of adhesion molecules and a ... -
Characterization of progressive periodontal lesions in chronic periodontitis patients: levels of chemokines, cytokines, matrix metalloproteinase-13, periodontal pathogens and inflammatory cells
(Blackwell, 2008)Background and aims: Periodontitis is an infection with an episodic nature of tissue support destruction. The aim of this work was to determine the levels of chemokines, cytokines, matrix metalloproteinase-13, periodontal ... -
Chemokine Monocyte Chemoattractant Protein-3 in Progressive Periodontal Lesions in Patients With Chronic Periodontitis
(American Academy of Periodontology, 2010-02)Background: Chemokines are central in the activation and direction of leukocyte subsets to target tissues. However, the monocyte chemoattractant protein-3 (MCP-3) has not been associated with chronic periodontitis. Chronic ... -
Chemokine RANTES in gingival crevicular fluid of adult patients with periodontitis
(Munksgaard, 2000-09)Background, aims: This study presents the first evidence on the presence of the chemokine RANTES in the gingival fluid crevicular (GCF) of patients with periodontitis. RANTES is a chemokine that selectively attracts and ... -
Clinical Attachment Loss in Chilean Adult Population: First Chilean National Dental Examination Survey
(AMER ACAD PERIODONTOLOGY, 2010-10)Background: Data from national surveys regarding the periodontal status of the adult population in Latin America are scarce. The aim of this study assesses the prevalence and extension of clinical attachment loss (AL) in ... -
Clinical Effects of Lactobacillus rhamnosus in Non-Surgical Treatment of Chronic Periodontitis: A Randomized Placebo-Controlled Trial With 1-Year Follow-Up
(American Academy of Periodontology, 2016-08)BACKGROUND: Probiotics are living microorganisms that provide beneficial effects for the host when administered in proper quantities. The aim of this double-masked placebo-controlled parallel-arm randomized clinical trial ... -
Clinical Effects of Lactobacillus rhamnosus in Non-Surgical Treatment of Chronic Periodontitis: A Randomized Placebo-Controlled Trial With 1-Year Follow-Up
(Amer Physical Soc., 2016)Background: Probiotics are living microorganisms that provide beneficial effects for the host when administered in proper quantities. The aim of this double-masked placebo-controlled parallel-arm randomized clinical trial ... -
Collagenase-2 (MMP-8) as a point-of-care biomarker in periodontitis and cardiovascular diseases. Therapeutic response to non-antimicrobial properties of tetracyclines
(Elsevier, 2011-02)Neutrophil collagenase or collagenase-2 (matrix metalloproteinase [MMP]-8) belongs to the collagenase subgroup of the MMP superfamily of calcium- and zinc-dependent neutral proteinases. MMP-8 is catalytically the most ... -
Delayed neutrophil apoptosis in chronic periodontitis patients
(Blacwell Munksgaard, 2003-07)Background, aims: Neutrophil cells constitute the first defense barrier against the oral bacterial challenge in the periodontium. Reduction of neutrophils could impair this response against periopathogenic bacteria such ... -
Dental Caries Prevalence and Tooth Loss in Chilean Adult Population: First National Dental Examination Survey
(Hindawi Publishing Corporation, 2012)The purpose of this study was to assess the prevalence of dental caries, tooth loss, and risk factors among adult population of Chile. Furthermore, age, gender, and behavioural specific differences in caries prevalence and ... -
Detection of Porphyromonas gingivalis in the amniotic fluid in pregnant women with a diagnosis of threatened premature labor
(2007)Background: Epidemiologic and randomized controlled studies have shown that periodontal diseases may be associated with preterm labor and delivery of infants with low birth weights. The purpose of the present study was to ... -
Diagnostic accuracy for apical and chronic periodontitis biomarkers in gingival crevicular fluid: an exploratory study
(Wiley, 2016)AimThe aim of this study was to assess the levels and diagnostic accuracy of a set of potential biomarkers of periodontal tissue metabolism in gingival crevicular fluid (GCF) from patients with chronic periodontitis (CP) ... -
Disparities in aspects of oral-health-related quality of life among Chilean adults
(Willey, 2013-06)Objective: Socioeconomic disparities in oral health among adults have been observed in many countries, but it is not clear whether they exist in aspects of Oral Health-Related Quality of Life in Chile. Methods: Data ... -
