Factors associated with edentulousness in an elderly population in Valencia (Spain) Factores asociados con el edentulismo en población anciana de Val…

2013

Objective: To determine the prevalence of edentulism and its association with various socioeconomic factors and oral health habits in the population aged 65-74 years old in the region of Valencia. Methods: A cross sectional study was designed. Thirty-four primary health centers and five nursing homes were chosen at random in the region of Valencia (10-15 voluntary participants per sampling point). Clinical examinations were carried out by three calibrated dentists (kappa>0.85) in the same centers. The total sample consisted of 531 individuals (235 men and 296 women). Results: The percentage of toothlessness was 20.7% and the mean number of natural teeth present was 14.92. The prevalence of …

Frequencies of pseudocholinesterase variants in Icelanders, Greeks and Pakistanis.

1968

THE formation of the human pseudocholinesterase variants is controlled by at least four alleles at one autosomal locus termed E1 (ref. 1). The four alleles are , , and (refs. 2–5). The heterozygotes have been found in remarkably uniform frequencies, about 3 to 6 per cent, in Caucasians from Europe and North America3,8–11, and also in Australian aborigines12 and Mexican Indians13, but are relatively rare among Negroes11 and Mongoloids10,11,14.

Oral health care activities performed by caregivers for institutionalized elderly in Barcelona-Spain

2013

Objectives: To describe the frequency of brushing teeth and cleaning of dentures, performed by caregivers, for institutionalized elderly people. Methods: A cross-sectional study in a sample of 196 caregivers of 31 health centers in Barcelona. The dependent variables were frequency of dental brushing and frequency of cleaning of dentures of the elderly by caregivers. The independent variables were characteristics of caregivers and institutions. We performed bivariate and multivariate descriptive analyses. Robust Poisson regression models were fitted to determine factors associated with the dependent variables and to assess the strength of the association. Results: 83% of caregivers were wome…

A lytic mechanism based on soluble phospholypases A2 (sPLA2) and b-galactoside specific lectins is exerted by Ciona intestinalis (ascidian) unilocula…

2011

Abstract Hemocytes from the ascidian Ciona intestinalis exert in vitro Ca 2+ -dependent cytotoxic activity toward mammalian erythrocytes and K562 cells. To examine the lytic mechanism, hemocyte populations were separated (B1–B6 bands) through a Percoll discontinuous density gradient, the hemocyte cytotoxic activity (HCA) and the lytic activity of the hemocyte lysate supernatant (HLS) were assayed. In addition the separated hemocytes were cultured and the cell-free culture medium (CFM) assayed after 3 h culture. Results support that unilocular refractile hemocytes (URGs), enriched in B5, are cytotoxic. The B5-HLS contains lysins and the activity of B5-CFM shows that lysins can be released in…

Relación entre la hepatitis crónica vírica B y/o C y el liquen plano bucal

2004

Introducción: La hepatopatía crónica es una patología producida, principalmente, por la ingesta alcohólica y por la infección de los virus de la hepatitis B y/o C. En los últimos años se ha discutido ampliamente la posible asociación entre la hepatopatía crónica y el liquen plano bucal. Recientemente, se ha especulado que la asociación entre liquen plano bucal y la enfermedad hepática tiene una base de origen vírica. Material y método: El objetivo de este estudio transversal emparejado es conocer si existe relación entre las hepatitis víricas B y/o C crónicas y el liquen plano bucal. Para ello, se seleccionaron dos grupos de 100 individuos cada uno: un grupo de casos, formado por pacientes …

TLR4 expression in ex-Lichenoid lesions—oral squamous cell carcinomas and its surrounding epithelium: the role of tumor inflammatory microenvironment

2022

Toll-like receptors (TLRs) regulate innate and adaptive immune responses. Moreover, TLRs can induce a pro-survival and pro-proliferation response in tumor cells. This study aims to investigate the expression of TLR4 in the epithelium surrounding oral squamous cell carcinomas (OSCC) in relation to its inflammatory microenvironment. This study included 150 human samples: 30 normal oral control (NOC), 38 non-lichenoid epithelium surrounding OSCC (NLE-OSCC), 28 lichenoid epithelium surrounding OSCC (LE-OSCC), 30 OSCC ex-non oral lichenoid lesion (OSCC Ex-NOLL), and 24 OSCC ex-oral lichenoid lesion (OSCC Ex-OLL). TLR4 expression was investigated by immunohistochemistry and the percentage of posi…

A preliminary study of hardness and modulus of elasticity in sheep mandibles submitted to distraction osteogenesis and low-level laser therapy

2011

Objectives: To investigate the quality of newly formed bone in sheep mandibles submitted to distraction osteogenesis and low-level laser therapy (LLLT), based on hardness and modulus of elasticity values. The ideal moment for laser application (during the latency/activation period vs. during the bone consolidation period) was also evaluated. Computed tomography imaging was used to assess relapse as a result of early device removal. Study design: Extraoral distraction devices were placed in five sheep so as to achieve 1.5 cm of lengthened bone in 60 days. Distraction devices were removed 50, 40, and 33 days after surgery. Four animals were treated with LLLT, at different times, and one was u…

Exéresis de las lesiones hiperplásicas de la cavidad bucal: estudio retrospectivo de 128 casos

2005

Objetivos: Este trabajo pretende, en base a nuestra experiencia, valorar y discutir las indicaciones, ventajas e inconvenientes de la exéresis de los épulis de la cavidad bucal con el láser de dióxido de carbono (CO2) respecto al láser de Erbio:YAG (Er: YAG), el láser de diodo y el bisturí frío. Material y método: Se ha realizado un estudio retrospectivo de un grupo de 120 pacientes en los que se extirparon 128 épulis con el láser de CO2, láser de Er:YAG, láser de diodo y bisturí frío. Se realizaron controles postoperatorios a los 7, 15 y 30 días para comprobar la cicatrización y la evolución de la herida y a los 3, 6 y 12 meses verificando si se había producido o no la recidiva de la lesió…
