Validation of the chinese version of the oral health impact profile for TMDs (OHIP- TMDs-C)
2015
Objectives: The aim of this study was to evaluate the reliability and validity of the the Chinese version of the Oral Health Impact Profile for TMDs (OHIP-TMDs-C). Study Design: The OHIP-TMDs was initially translated and cross-culturally adapted to Chinese following international guidelines; then subsequently validated for the psychometric characteristics of reliability and validity. In total, 156 participants with temporomandibular disorders (TMDs) were recruited to complete the questionnaire. The reliability of the OHIP-TMDs-C was evaluated using internal consistency and test-retest methods. The validity of the OHIP-TMDs-C was analysed by construct validity and convergent validity. Constr…
Dental considerations in patients with heart disease
2011
Summary: Cardiovascular diseases are one of the main causes of death in the developed world, and represent the first cause of mortality in Spain. In addition to their associated morbidity, such disorders are important due to the number of affected individuals and the many patients subjected to treatment because of them. Objective: An update is provided on the oral manifestations seen in patients with arterial hypertension, ischemic heart disease, arrhythmias and heart failure, and on the dental management of such patients. Material and methods: A Medline-PubMed search was conducted of the literature over the last 10 years using the keywords: “cardiopathy”, “dental management”, “endocarditis…
Prospective study of a group of pre-university students evaluating anxiety and depression relationships with temporomandibular disorders
2012
Objectives: The aim of this prospective longitudinal study was to evaluate the relationships between anxiety, depression, and temporomandibular disorders (TMD) in a sample of pre-university students submitted to a stressful event. Study design: 153 students from a pre-university course (82 females and 71 males between 16 and 31 years old) were given a survey about TMD symptoms and a survey about anxiety and depression scale at the beginning and the end of the preparatory course (August 2009-T1, and November 2009-T2). Results: Results were analyzed using a chi-square test and Odds Ratio (OR), significance level of á = 0.05. Statistical significance were found to depression rates in students …
Health-related quality of life after mandibular resection for oral cancer: reconstruction with free fibula flap
2014
Objectives: Mandibular resection for oral cancer is often necessary to achieve an adequate margin of tumor clear - ance. Mandibular resection has been associated with a poor health-related quality of life (HRQOL), particularly before free fibula flap to reconstruct the defect. The aim of this study was to evaluate health-related quality of life in patients who have had mandibular resections of oral cancer and reconstruction with free fibula flap. Study D esigns: There were 115 consecutive patients between 2008 and 2011 who were treated by primary surgery for oral squamous cell carcinoma, 34 patients had a mandibular resection. HRQOL was assessed by means of the 14-item Oral Health Impact Pr…
A large ameloblastic fibro-odontoma of the right mandible
2007
The ameloblastic fibro-odontoma is a rare mixed odontogenic tumor. It occurs predominantly in children and young adults with no sex predilection and locates most often in the posterior segment of the mandible. A painless swelling is the most common clinical sign. Radiologically, ameloblastic fibro-odontoma shows a circumscribed radiolucency, which contains radio-opaque foci of various sizes and shapes. Histological examination reveals a fibrous soft tissue, islands of odontogenic epithelium and a disordered mixture of dental tissues. The tumor produces enamel or enamel matrix, dentin and cementum. The treatment of ameloblastic fibro-odontomas usually consists of enucleation or surgical cure…
Evolución del germen dental trasplantado heterotópicamente en la dermis: un estudio histológico en la rata
2004
En este estudio hemos analizado la potencialidad de desarrollo del germen dental en fase de corona. Para ello, los gérmenes dentales de rata recién nacida fueron trasplantados en las bolsas dérmicas de la oreja de ratas isogénicas. Siete y catorce días después del trasplante, se desarrollaron las estructuras morfológicas dentales típicas, con ameloblastos y odontoblastos bien diferenciados. Ulteriormente, los procesos de reacción inflamatoria del tejido huésped con infiltración celular abocaron a la desaparición de los tejidos dentales. Desde el primer momento de nuestro análisis, los trasplantes desarrollaron una dentina anómala u osteoide cuyo tamaño fue paulatinamente incrementando con e…
Asociación entre alteraciones psicológicas y la presencia de Liquen plano oral, Síndrome boca urente y Estomatitis aftosa recividante
2004
OBJETIVO: El propósito de este estudio fue determinar la relación existente entre el Liquen Plano Oral (LPO),Estomatitis Aftosa Recividante (EAR), Síndrome de Boca Urente (SBU) y las alteraciones psicológicas del paciente, tales como el estrés, la ansiedad y la depresión. DISEÑO DEL ESTUDIO : Fueron estudiados 18 pacientes con EAR , 9 pacientes con LPO y 7 pacientes con SBU, que presentaron la lesión en el momento del examen, más un grupo control de 20 pacientes sanos. Ambos grupos fueron extraídos de centros hospitalarios y docentes, donde el diagnóstico clínico fue realizado por un equipo de patólogos orales. A los pacientes se les aplicó dos instrumentos de medición del estado psicológic…
Manifestaciones orales de la infección por VIH en la infancia: artículo de revisión
2004
La gran mayoría de niños con infección por VIH presentan, dentro de sus primeros signos de enfermedad, manifestaciones orales. Estas lesiones orales no están producidas directamente por dicho virus, son manifestaciones asociadas a la infección por VIH, ya que no son patognomónicas de la infección. Algunas de estas lesiones orales tienen un valor pronóstico de cara a la evolución de la infección y la aparición de SIDA, independientemente de otros marcadores de uso más común. Los factores de riesgo esenciales que predisponen al desarrollo de dichas manifestaciones orales son el bajo número de linfocitos T CD4+, xerostomía y la ausencia de tratamiento antiretroviral. Infecciones oportunistas c…

Dental problems are frequent and include: ogival palate, micrognathia, dental malalignment, delayed teething, microdontic teeth, periodontal disease and dental erosion produced by gastric reflux. Discussed is the case of a 29 year old patient affected by the syndrome in question, which presents the principal clinical characteristics. The patient?s general state of health is acceptable, without car…
