Evaluación del grado de queratinización y el recuento de AgNORs en citología exfoliativa de mucosa oral normal de individuos fumadores y no fumadores
2004
Objetivos. En individuos fumadores con mucosa oral clínicamente sana, se han observado cambios citológicos como una mayor queratinización, existiendo también reportes de un mayor grado de actividad nucleolar. En estos estudios, las células para frotis se han obtenido por medio de espátula de madera. Nuestro objetivo es evaluar la profundidad de muestras citológicas de mucosa oral obtenidas con cepillo para frotis (endobrush) y comparar el grado de queratinización y la actividad nucleolar en pacientes fumadores y no fumadores. Diseño del estudio. Se obtuvieron frotis de mucosa oral de borde de lengua clínicamente normal de 30 individuos fumadores y 30 no fumadores, utilizando espátula de mad…
Latex allergy in dentistry: clinical cases report
2010
Generally natural rubber latex (NRL) allergy is detected after some exposition to the material. As NRL is com- monly found in different materials used daily in dental clinic, the allergy can be manifested in the pediatric dentistry clinic. The first clinical manifestation can be smooth but also severe, therefore it is important to know different manifestations and how to prevent them. Objective: Report two clinical cases of natural rubber latex allergy in children and to present the safety measures that must be taken during clinical assistance, as using metallic saliva ejector, vinyl gloves for the treatment procedures and as an option to rubber dam. Cases Report: Case 1- Patient presented …
Usefulness of salivary alpha amylase as a biomarker of chronic stress and stress related oral mucosal changes ' a pilot study
2013
Introduction: Salivary biomarkers are suggested to provide a reliable, noninvasive and objective measurement of chronic psychosocial stress and helps in assessment of pivotal role of stress in causation or precipitation of multitude of health problems. Objectives: To evaluate the usefulness of salivary alpha amylase activity as an objective indicator of chronic stress and to find out any correlation between stress- related mucosal complaints and its levels. Study Design: Study was conducted among 50 subjects suffering from chronic stress related problems and 50 non-stressed individuals who were screened with a psychometric questionnaire. Brief case history and oral examination was carried o…
Haemostatic agents on the shear bond strength of self-adhesive resin
2015
Background Dentin surface contaminated with haemostatic agents can interfere with the bonding of self-adhesive resin cement. Therefore the purpose of this study was to evaluate the effect of various haemostatic agents such as Aluminium chloride, Ferric sulphate and Tannic acid on the shear bond strength of self-adhesive resin luting agent. Material and Methods The buccal surfaces of extracted premolars were flattened to expose the dentine. The teeth were then randomly divided into four groups. In Group I Aluminium Chloride was applied on the flattened dentinal surface, in Group II Ferric Sulphate was applied to exposed dentin surface, in Group III tannic acid was applied on to the dentinal …
Cardiopatías y enfermedades periodontales: ¿existen evidencias de asociación?
2005
Las enfermedades cardiovasculares representan una de las principales causas de muerte en las sociedades desarrolladas. Estas enfermedades no sólo son importantes por la mortalidad que generan, sino por la gran cantidad de individuos afectados y en tratamiento que han de soportar los sistemas de salud de los distintos países. De ahí que la detección precoz de los factores de riesgo conducentes a desencadenar estas enfermedades haya sido vista como el mecanismo más eficaz para prevenirlas. En los últimos tiempos se viene relacionando de una manera más o menos directa a la patología periodontal con el padecimiento de enfermedades cardiovasculares. Este hecho podría tener una gran relevancia cl…
Estudio del análisis de frecuencia de resonancia tras la colocación de 133 implantes dentales
2006
Introducción: La estabilidad primaria del implante dental está relacionada con el hueso que se encuentra en contacto con él y se puede medir mediante el análisis de frecuencia de resonancia. Material y métodos: En 133 implantes (62 en maxilar y 71 en mandíbula) se midió la frecuencia de resonancia y la fuerza de inserción para conocer la estabilidad de los implantes el día de la cirugía, y estudiar su relación con distintas variables. Resultados: El cociente de estabilidad del implante obtenido el día de la cirugía fue de 62'1 y el de la fuerza de inserción fue de 35'7 Nw. La fuerza de inserción fue proporcional al análisis de la frecuencia de resonancia, a mayor fuerza de inserción mayor c…
Salivary gland choristoma in the buccinator muscle: A case report and literature review
2015
Salivary gland choristoma (SGCh) is defined as the presence of normal salivary tissue in an abnormal location. It is a rare entity in oral and maxillofacial region and its ethiology is unknown. The typical presentation of salivary gland heterotopia is an asymptomatic mass that may or may not produce saliva. Some examples of ectopic salivary tissue in the pituitary gland, in the lymph nodes, in the middle ear, in the neck, in the jaw, in the thyroid gland, in the mediastinum and in the rectum have been documented in literature. We report the case of a 61-year-old male presented with a bilateral tumorlike mass in the cheek. The mass was painless, of fibrous consistency and had size change wit…
Alternative surgical management of oroantral fistula using auricular cartilage
2015
One of the clinical complications encountered by oral and maxillofacial surgeons is oroantral communication (OAC) with subsequent formation of oroantral fistula (OAF). Many techniques and treatment modalities have been described for the management of OAC and OAF. There are advantages and disadvantages of all these techniques. We report a 21-year-old male patient who was admitted to our department for the presence of an OAF and was treated using an auricular cartilage graft. This technique may be useful to treat OAF and to provide a solid alveolar bone site for subsequent pre-implant surgery. Key words:Auricular cartilage, implant surgery, oroantral fistula.

Dental research in Spain. A bibliometric analysis on subjects, authors and institutions (1993-2012)
2016
Background Bibliometrics is defined as the use of statistical methods in the analysis of a body of literature to reveal the historical development of subject fields and patterns of authorship, publication, and use. Our objective was to characterize Spanish scientific output in Dentistry through the analysis of Web of Science database in a 20-year period. By means of a bibliometric study documents were statistically analyzed using indicators that showed quantitative and qualitative aspects of the production. Specifically, time course of the scientific production within the time span was analysed, as were the journals where the article was published and the categories of Journal Citation Repo…
