The Effect of a Mediterranean Diet on the Incidence of Cataract Surgery
2017
Background: Cataract is a leading cause of vision impairment worldwide, and surgery is the only available treatment. The process that initiates lens opacification is dependent on the oxidative stress experienced by the lens components. A healthy overall dietary pattern, with the potential to reduce oxidative stress, has been suggested as a means to decrease the risk of developing cataract. We aimed to investigate the hypothesis that an intervention with a Mediterranean diet (MedDiet) rather than a low-fat diet could decrease the incidence of cataract surgery in elderly subjects. Methods: We included 5802 men and women (age range: 55-80 years) from the Prevencion con Dieta Mediterronea study…
Endoluminal sclerosis with diode laser in the treatment of orofacial venous malformations
2012
Introduction: The appearance of vascular anomalies in the orofacial area is a common condition, which represents about 50% of these malformations. Traditional treatment approach, such as surgery and chemical sclerosis has been given way to a few less-invasive options, as the use of the 810nm diode laser to induce the sclerosis of the venous malformation by intralesional photocoagulation. Objectives: The objective of this study was to determine the efficacy of the diode laser in the intralesional treatment of the orofacial venous malformations (OFVM), describing the recommended surgical approach, as well as to report the main associated complications. Patients and Methods: 10 cases of OFVM, …
Severe scleral dellen as an early complication of pterygium excision with simple conjunctival closure and review of the literature
2014
Descrevemos um paciente com "dellen" escleral agudo (SD) após excisão de pterígio com fechamento conjuntival simples. Uma revisão adicional da literatura médica sobre SD precoce após a cirurgia de pterígio também é realizada. Este caso descreve um homem de 45 anos de idade, que apresentou SD grave, sete dias após a cirurgia de pterígio com cauterização mínima de vasos episclerais e fechamento conjuntival simples. Nenhuma outra terapia adjuvante foi utilizada no intraoperatório. O paciente recusou-se à cobertura de retalho conjuntival da lesão. Portanto, o tratamento médico consistiu em pomada antibiótica, oclusão e acompanhamento diário. Após sete dias, a oclusão foi mudada para a lubrifica…
Complications of guided surgery and immediate loading in oral implantology: a report of 12 cases.
2011
Objectives: The growing interest in minimally invasive surgery, together with the possibility of fitting prostheses with immediate function, have led to the development of software capable of planning and manufacturing a surgical guide and prosthesis that can be placed upon conclusion of the implant surgery step. The present study evaluates the surgical and prosthetic complications of implant treatment with the guided surgery technique, together with patient comfort during and after treatment. Patients and methods: A retrospective observational study was made of 19 patients with partially or totally edentulous upper and/or lower maxillae, involving the placement of a total of 122 implants. …
Development and viability of biofilms grown on experimental abutments mimicking dental implants: an in vivo model
2019
Background To determine whether an experimental abutment mimicking the macro- and microstructure of a dental implant is a suitable method for recovering biofilm, and to describe the features of biofilms formed around such abutments on healthy implants. Material and Methods Experimental abutments were used in 15 patients without peri-implant diseases. After 14 days’ absence of dental hygiene in this area, the abutments were retrieved and analyzed through confocal laser scanning microscopy and scanning electron microscopy. The biofilm formation on the surface of the first 5 abutments was determined by a fluorescence-staining method using SYTO9 nucleic acid stain. In order to study the biofilm…
Estudio del efecto de los bifosfonatos (zoledronato) sobre la consolidación de las fracturas
2011
INTRODUCCIÓN La osteoporosis es una enfermedad sistémica crónica y progresiva que se caracteriza por una densidad ósea baja y por un deterioro de la micro-arquitectura del tejido óseo, que aumenta la probabilidad de sufrir una fractura ante mínimos traumatismos171. La incidencia de este tipo de fracturas es muy alta y además está en aumento151 debido al envejecimiento de la población. Dentro del tratamiento de la osteoporosis los bifosfonatos son los fármacos más utilizados al ser los que han demostrado mayor efectividad en la prevención de fracturas vertebrales, de cadera y periféricas19,87. Su principal efecto es la inhibición de la reabsorción ósea mediada por osteoclastos179. Dentro del…
Clinician-related factors behind the decision to extract an asymptomatic lower third molar. A cross-sectional study based on Spanish and Portuguese d…
2017
Background: Scientific literature estimates that around 18 to 40 % of asymptomatic third molars are extracted. The aims of the present study were to determine the indications for extraction of asymptomatic lower third molars in a sample of Spanish and Portuguese dentists, and to relate these indications to the clinicians’ training and professional experience. Material and Methods: A survey consisting of 15 cases of asymptomatic lower third molars was emailed to Portuguese and Spanish dentists. The clinicians were asked to assess the level of difficulty of the extractions and to make a reasoned recommendation based on the panoramic radiographs, gender and age of the patients. Results: 381 cl…
Predictive factors of difficulty in lower third molar extraction : a prospective cohort study
2017
Background Several publications have measured the difficulty of third molar removal, trying to establish the main risk factors, however several important preoperative and intraoperative variables are overlooked. Material and Methods A prospective cohort study comprising a total of 130 consecutive lower third molar extractions was performed. The outcome variables used to measure the difficulty of the extraction were operation time and a 100mm visual analogue scale filled by the surgeon at the end of the surgical procedure. The predictors were divided into 4 different groups (demographic, anatomic, radiographic and operative variables). A descriptive, bivariate and multivariate analysis of th…
Impacted lower third molars and distal caries in the mandibular second molar. Is prophylactic removal of lower third molars justified?
2017
Background The objective of this study was to evaluate the association between the presence of mandibular third molars and the occurrence of carious lesions in the distal aspect of the mandibular second molar. Material and methods A retrospective cohort study comprising 327 lower third molars extracted in the Oral Surgery and Implantology Master's Degree program of the School of Dentistry of the University of Barcelona (Barcelona, Spain) was carried out. A descriptive and bivariate analysis was made. The diagnosis of caries in the second molar and the position of the mandibular third molar were evaluated through panoramic radiographies. Results The sample included 203 patients, 94 males (46…
Antibacterial suture vs silk for the surgical removal of impacted lower third molars. A randomized clinical study.
2015
Background The aim of this study was to evaluate the clinical and microbiological impact of an antibacterial suture (Monocryl® Plus) in the surgical removal of I3M. Material and Methods A “split-mouth”, prospective pilot clinical study was designed involving 20 patients programmed for the surgical removal of I3M. Each side was randomly sutured with Monocryl® Plus or silk suture and removed for microbiological study 72 hours and 7 days after surgery. Presence of SSI, wound bleeding and the degree of discomfort associated with each type of suture material (scored by means of a visual analog scale) were evaluated. The level of contamination of each material was observed under the scanning elec…
