Presentación del tumor de Pindborg de forma mandibular doble. A propósito de un caso

El tumor odontogénico epitelial calcificante (TOEC) es una rara lesión de los maxilares. Este artículo describe un caso singular en un varón de 22 años. Presenta dos TOEC, uno en el lado derecho de la mandíbula y otro en el izquierdo, con los tres elementos típicos del TOEC: células epiteliales con citoplasma eosinófilo, sustancia eosinófila homogénea y depósito de calcio

Fisiopatología de la luxación del cóndilo mandibular

Se analizan las características fisiopatológicas de la subluxación y luxación de la articulación temporomandibular. Se revisan las distintas variedades de luxación del cóndilo mandibular, así como las causas más frecuentes que determinan la aparición de esta patología. Ciertas condiciones anatómicas, tales como roturas ligamentosas, alteraciones capsulares y del menisco favorecen la luxación recidivante bloqueada. La incoordinación de los músculos de la masticación y el mioespasmo pueden ser factores determinantes de la luxación anterior

Techniques for early diagnosis of oral squamous cell carcinoma: systematic review

Background and objectives: The diagnosis of early oral potentially malignant disorders (OPMD) and oral squamous cell carcinoma (OSCC) is of paramount clinical importance given the mortality rate of late stage disease. The aim of this study is to review the literature to assess the current situation and progress in this area. Material and Methods: A search in Cochrane and PubMed (January 2006 to December 2013) has been used with the key words “squamous cell carcinoma”, “early diagnosis” “oral cavity”, “Potentially Malignant Disorders” y “premalignant lesions”. The inclusion criteria were the use of techniques for early diagnosis of OSCC and OPMD, 7 years aged articles and publications written in English, French or Spanish. The exclusion criteria were case reports and studies in other languages. Results: Out of the 89 studies obtained initially from the search 60 articles were selected to be included in the systematic review: 1 metaanalysis, 17 systematic reviews, 35 prospective studies, 5 retrospective studies, 1 consensus and 1 semi-structured interviews. Conclusions: The best diagnostic technique is that which we have sufficient experience and training. Definitely tissue biopsy and histopathological examination should remain the gold standard for oral cancer diagnose. In this systematic review it has not been found sufficient scientific evidence on the majority of proposed techniques for early diagnosis of OSCC, therefore more extensive and exhaustive studies are needed

Osteoma de la escotadura sigmoidea mandibular. Descripción de un caso

Se describe un caso de osteoma periférico del maxilar inferior de localización excepcional en la escotadura sigmoidea. Se trataba de un paciente de 73 años, con dolor a nivel de la articulación temporomaxilar izquierda, limitación de la apertura bucal y que referia la percepción de un roce al masticar. La radiografia lateral, tomografia y ortopantomografia confirmaron la presencia de un tumor bilobulado en la escotadura sigmoidea mandibular. Tras la exéresis quirúrgica por vía preauricular, el estudio histológico confirmó el diagnóstico de osteoma al observarse tejido óseo muy denso formado por trabéculas amplias e irregulares con escaso tejido intertrabecular. La evolución ha sido favorable con apertura y cierre bucal correctos y recuperación progresiva del funcionalismo articular

Scientific evidence on the usefulness of intraarticular hyaluronic acid injection in the management of temporomandibular dysfunction

Hyaluronic acid (HA) is found in high concentrations in cartilage and synovial fluid, and is an important component of the extracellular matrixes- exerting joint lubrication and buffering actions thanks to its viscoelastic properties. The present study examines the scientific evidence found in the current literature on the usefulness of the intraarticular injection of HA in patients with temporomandibular dysfunction. A literature search was made up until May 2008 in the following databases: PubMed / MEDLINE. Of the articles found in the literature, the present review included 18 relevant studies on the application of HA in the temporomandibular joint (TMJ). The quality, level of evidence and strength of recommendation of the articles was evaluated based on the"Strength of Recommendation Taxonomy" criteria. It is concluded that type A level of recommendation exists in favor of the intraarticular injection of HA in dysfunction of the TMJ. However, further studies are needed to establish the true therapeutic effects and to identify the best dosing regimen

Mediastinitis odontogénicas

Las mediastinitis secundarias a infecciones dentarias ocurren raramente. El diagnóstico es difícil y a menudo se retrasa provocando la muerte del enfermo. A los datos tradicionales de edema y crepitación de cuello y tórax como signos de alarma, hemos sumado el de tos no productiva, obtenido de nuestra propia experiencia. Hemos revisado un total de 25 casos publicados. resaltando el dato de que 22 fueron varones

Compliance of postoperative instructions following the surgical extraction of impacted lower third molars: a randomized clinical trial

Objectives: The understanding and adherence to postoperative care instructions are factors that influence the recuperation process after any surgical procedure. The aim of this study was to determine the percentage of patients who strictly follow the postoperative instructions after the extraction of an impacted lower third molar in relation to sociocultural level, preoperative anxiety scores and how postoperative information is provided to the patient. Study Design: Patients were randomly assigned to one of three different test groups according to how the postoperative instructions were presented: verbal, written and a group that received additional information. Before surgery, patients were required to complete the Corah Dental Anxiety Scale and personal information (age, gender and educational level) was also collected. P <0.05 was considered significant. Patients were surveyed a week after surgery regarding their adherence to postoperative instructions. Results: 84 patients (45 women and 39 men with an average of 28.23 ± 7.41 years) completed the study. There were no statistically significant differences regarding adherence of postoperative care instructions depending on the manner of instruction presentation, preoperative anxiety level and sociocultural level ( p > 0.05). Quitting smoking or drinking of alcoholic/carbonated beverages were the main influential factors for the lack of adherence to postoperative care instructions during the week after surgery. Conclusions: Presentation of postoperative instructions, preoperative anxiety scores and sociocultural level do not appear to be key factors that promote the adherence to postoperative instructions

Sensory disturbances of buccal and lingual nerve by muscle compression: a case report and review of the literature

Introduction: several studies on cadavers dissection have shown that collateral branches of the trigeminal nerve cross muscle bundles on their way, being a possible etiological factor of some nerve disturbances. Case Report: a 45-year-old man attended to the Temporomandibular Joint and Orofacial Pain Unit of the Master of Oral Surgery and Implantology in Hospital Odontològic of Barcelona University, referring tingling in the left hemifacial región and ipsilateral lingual side for one year, with discomfort when shaving or skin compression. Discussion: several branches of the trigeminal nerve follow a path through the masticatory muscles, being the lingual nerve and buccal nerve the most involved. The hyperactivity of the muscle bundles that are crossed by nerve structures generates a compression that could explain certain orofacial neuropathies (numbness and / or pain) in which a clear etiologic factor can not be identified
