The use of tricyclic antidepressants in the treatment of temporomandibular joint disorders: systematic review of the literature of the last 20 years

2009

Many therapies have been proposed for the management of temporomandibular disorders, including the use of different drugs. However, lack of knowledge about the mechanisms behind the pain associated with this pathology, and the fact that the studies carried out so far use highly disparate patient selection criteria, mean that results on the effectiveness of the different medications are inconclusive. This study makes a systematic review of the literature published on the use of tricyclic antidepressants for the treatment of temporomandibular disorders, using the SORT criteria (Strength of recommendation taxonomy) to consider the level of scientific evidence of the different studies. Followin…

Tratamiento de la anquilosis de la articulación temporomandibular por artroplastia simple

2006

Objetivo: El propósito de este trabajo es mostrar que la artroplastia simple mejora la apertura bucal al tratar la anquilosis temporomandibular. Pacientes y métodos: Fueron tratados ocho pacientes con anquilosis de la articulación temporomandibular por medio de artroplastia simple. Los pacientes fueron evaluados en el postoperatorio por un periodo por lo menos de veinticuatro meses (mínimo 24 y máximo 48 meses). Resultados: De los ocho pacientes (once articulaciones), cinco (62,5%) presentaron afectación unilateral y tres pacientes (37.5%) afectación bilateral de la ATM. La edad media fue de 20 años ± 9 (rango de 3 a 30 años). La máxima apertura bucal en el período preoperatorio fue de 9,25…

The Relationship Between Tooth Size Discrepancy and Archform Classification in Orthodontic Patients

2015

Background: To determine the relationship between clinically significant tooth size discrepancies (TSD) and archform classification in orthodontic patients. Material and Methods: Two hundred and forty consecutive sets of pre-treatment orthodontic study models were scanned and landmarked. All models had permanent teeth erupted from first molar to first molar in both arches. Sixty sets of images were classified into two groups of 30 according to the presence (group 1) or absence (group 2) of a clinically significant overall or anterior TSD (>2 SD from Bolton’s original means). Mean upper and lower archforms were created for each group using a fourth degree polynomial curve. Upper and lower ar…

Risk Factors Associated with Carious Lesions in Permanent First Molars in Children: A Seven-Year Retrospective Cohort Study

2020

The aim of this study was to evaluate the risk factors associated with the occurrence of caries in permanent teeth (PT) and in the permanent first molar (PFM) seven years after their eruption. Children born in 2005 who were enrolled in a Community Dental Program were included. A total of 278 children were enrolled. Evaluated risk factors were parental caries experience, educational level of the mother, routine medications, systemic diseases, dietary habits, toothbrushing frequency, existence of molar incisor hypomineralization (MIH) in the PT, and caries in the temporary teeth (TT). Associations between independent variables and the DMF-T (decayed, missing, and filled teeth in PT) and DMF-M…

Cranial circulation of the pen-tailed tree shrewPtilocercus lowii and relationships of Scandentia

1994

The major cranial arteries and veins are described for a 30-mm crown-rump length fetus of the pen-tailed tree shrewPtilocercus lowii, and comparisons are made with cranial vessels reported in the tree shrewTupaia and with the vascular pattern reconstructed for primitive eutherians.Ptilocercus shares a number of derived features of the cranial circulation withTupaia, which, therefore, represent synapomorphies of tree shrews (Tupaiidae, Scandentia). Included are (1) the enclosure of the intratympanic portion of the internal carotid artery in a bony canal that is floored proximally and distally by the entotympanic and by the petrosal in between, (2) the enclosure of the intratympanic portion o…

Estudio anatómico del tercer molar mandibular incluido

2015

Los terceros molares son los últimos dientes en erupcionar, debido a ello no encuentran suficiente espacio para establecerse en el arco dentario, por lo que fácilmente pueden quedar retenidos. El diagnóstico inadecuado del tercer molar inferior incluido puede ser causa de numerosas complicaciones como infecciones odontogénicas, tumores benignos, malignos, caries dental entre otros. Por ello el objetivo de este estudio es conocer el desarrollo del tercer molar mandibular, analizar los cambios que se producen en su desarrollo y el espacio disponible para su erupción, relacionándolo con la edad, sexo y localización del tercer molar en la arcada. La población de estudio fue de 300 pacientes con…

Enfermedad de Jacob asociada con el síndrome de disfunción de la articulación temporomandibular: presentación de un caso

2005

La enfermedad de Jacob se describe como una entidad infrecuente en la cual se establece una formación articular sinovial entre una apófisis coronoide mandibular elongada y el hueso malar homolateral. El Síndrome de disfunción de la articulación temporomandibular (ATM) ha sido postulado como posible factor etiológico del alargamiento este proceso coronoideo. Presentamos el caso de una mujer de 23 años con un desplazamiento discal de ATM de larga evolución y limitación de la apertura oral, que desarrolló una asimetría malar progresiva. La paciente fue sometida a tratamiento quirúrgico mediante una coronoidectomía intraoral y una artroscopia de la ATM homolateral en el mismo acto operatorio. E…

Spontaneous fracture of the mandibular genial tubercles: A case report

2007

Fracture of the mandibular genial tubercles is an uncommon pathology affecting edentulous patients with severe maxillary atrophy. Usually occurs spontaneously which complicates the diagnosis. Their importance lies in the functional alterations, which occur as a consequence of the disinsertion of the genihyoid and genioglossus muscles. The treatment of fracture of the genial tubercles is controversial, including no surgical intervention, excision of the avulsed bone fragments, and muscular repositioning. There have been only 11 cases reported in the literature of this fracture, most of them spontaneous. We present a difficult diagnosis situation of spontaneous fracture of the genial tubercle…

Anatomía de la sínfisis mandibular según la clase esquelética y el patrón facial

2015

El objetivo de la tesis doctoral es estudiar la relación entre el tejido duro y blando de la sínfisis mandibular en los distintos patrones faciales y clases esqueléticas de los pacientes mediante un analisis cefalométrico diseñado expresamente para el estudio con un software digital. Para el estudio se seleccionaron 385 radiografías laterales pertenecientes a pacientes mayores de 22 años del máster de ortodoncia de la Facultad de Odontología de Valencia. Los pacientes se dividieron en grupos según la clase esquelética (Cl I, II y III esquelética) mediante el Witts Apraisal y según el patrón facial (dolicofacial, medofacial y braquifacial ) mediante el eje facial de Ricketts, obteniendo una …
