Prevalence, etiology, diagnosis, treatment and complications of supernumerary teeth
2014
The aim of this article was to review the literature on supernumerary teeth, analyzing their prevalence, etiology, diagnosis, treatment and possible complications. An electronic search was made in the Pubmed-Medline database up to January 2014 using the key search terms "multiple supernumerary teeth" (n=279), "prevalence supernume rary teeth" (n=361), and "supernumerary teeth" (n=2412). In addition to the articles initially identified, others were included in the review proceeding from a manual search and from any references considered of relevance. Supernumerary teeth are those that exceed the normal dental formula. They are more common in men, more common in the upper maxilla, and more pr…
Consensus Report of the XI Congress of the Spanish Society of Odontology for the Handicapped and Special Patients
2014
This article summarizes the findings of consensus of the XI congress of the SEOEME. All of these conclusions are referring to the review articles responsible to the general rapporteurs in order to bringing up to date knowledge with regard to the use of implants in patients medically compromised and with special needs and, in the dental management of autism and cerebral palsy, in the dental treatment of patients with genetic and adquired haemato - logical disorders, the dental implications of cardiovascular disease and hospital dentistry.
Clinical features and histological description of tongue lesions in a lar ge Northern Italian population
2015
Background: Only few studies on tongue lesions considered sizable populations, and contemporary literature does not provide a valid report regarding the epidemiology of tongue lesions within the Italian population. In this report, the histopathological and clinical appearance of 1.106 tongue lesions from northern Italians are described and discussed. Material and Methods: The case records of patients referred for the diagnosis and management of tongue lesions, from October 1993 to October 2013, were reviewed. Histological data were also obtained and blindly reexamined. Results: For instance, a biopsy performed on a lingual ulcer has a strong predicting association with a carcinoma, whereas …
Management of tooth discoloration in non-vital endodontically treated tooth: a report of 6 year follow-up
2011
Discoloration of teeth, especially the anteriors, can result in considerably cosmetic impairment in young children. It is the pediatric dentist’s responsibility to supervise those children who seek to undergo a whitening treatment to ensure the maximum cosmetic benefit within the boundaries of oral and systematic health. Among bleaching techniques, the walking bleach technique with sodium perborate and distilled water stands out because of its superior esthetic results with no side effects. This paper presents a case of tooth discoloration in non-vital tooth which was successfully bleached using walking bleach method. After 6 year follow up the prognosis was good with no reversal of tooth d…
Fibroma óseo juvenil: a propósito de un caso clínico
2004
Se presenta el caso clínico de un paciente de 8 años de edad con un fibroma osificante juvenil en el ángulo mandibular derecho y un quiste radicular en el ángulo mandibular izquierdo, los cuales producían un importante abombamiento a nivel de los ángulos mandibulares e impedían la correcta erupción de los primeros molares inferiores. Tras el estudio clínico y radiológico ( Ortopantomografía y Scan dental del maxilar inferior), se llevó a cabo el correspondiente tratamiento quirúrgico (quistectomía y remodelación de los mismos) y el estudio histopatológico. Aunque el fibroma óseo juvenil es una entidad clínica poco frecuente, debido al comportamiento local agresivo y a la recidiva que tiene,…
Florid cemento-osseous dysplasia: report of a case documented with clinical,radiographic, biochemical and histological findings
2013
Florid cemento-osseous dysplasia (FCOD) has been described as a condition that characteristically affects the jaws of middle-aged black women. This condition has also been classified as gigantiform cementoma, chronic sclerosing osteomyelitis, sclerosing osteitis, multiple estenosis and sclerotic cemental masses. It usually exhibits as multiple radiopaque cementum-like masses distributed throughout the jaws. Radiographically, FCOD appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. Computed tomography, because of its ability to give axial, sagittal, and frontal views, is useful in the evaluation of these lesions. This article reports the case of a …
An observational study of the frequency of supernumerary teeth in a population of 2000 patients
2007
An evaluation is made of the epidemiological characteristics of supernumerary teeth, with an analysis of the associated clinical-eruptive complications. A longitudinal observational study was made of 2000 patients, with the documentation of demographic data, the presence of supernumerary teeth, their location, mechanical accidents and the presence of associated pathology. The presence of supernumerary teeth was recorded in 1.05% of the study subjects (mean age 20.2 years), with a greater frequency in males. The most frequent location was in the upper maxilla (79.2%), fundamentally in the retromolar zone and at premaxillary level. The presence of mechanical accidents was the most frequent co…
Injerto óseo simultáneo a la colocación de implantes: a propósito de un caso
2005
Los defectos óseos a nivel de la cresta alveolar mandibular dificultan la colocación de los implantes dentales en el lugar idóneo. La reconstrucción quirúrgica mediante injertos de hueso autólogo es una opción que permite la fijación de los implantes de manera estética y funcional. Presentamos un paciente con grandes pérdidas óseas mandibulares, secundarias a procesos inflamatorios periodontales. Se realizó la reconstrucción del proceso alveolar mandibular, empleando injertos en bloque, tipo onlay, tomados de la mandíbula. Los injertos fueron estabilizados al colocar los implantes a través de ellos, consiguiéndose además una buena fijación primaria de los mismos. Tras dos años de seguimient…
Use of bone plates and screws to manage chronic mandibular dislocation
2010
Different treatment modalities are described in literature to treat mandibular recurrent dislocation, including intra- capsular esclerosant injections, articular eminence reduction, soft tissues suture to limit condilar movement, and grafts or implants to create mechanical interference, like zygomatic arch down fracture or articular eminence in- crease by bone plates. In this paper, a patient with mandibular recurrent dislocation episodes were eliminated after bilateral fixation of bone plates to the lateral sur-face of the zygomatic arch to restrict mandibular movements. One arm of the plate was extended me-dially just below the articular eminence and fixed at lateral zygomatic arch portio…
Patient-specific factors in the proximity of the inferior alveolar nerve to the tooth apex
2012
Objectives: To evaluate whether age and gender differences are predictive factors for inferior alveolar nerve position with respect to mandibular first molar roots. Study Design: Cone-beam computed tomography scans [0.2-mm 3 voxel size; n = 200 (100 males, 100 females)] of patients aged 15-65 years showing mandibular first and second molars were included in this study. Patients with pathoses that might affect inferior alveolar nerve position, including second molar and/or first premolar extraction, were excluded. Fourteen measurements (mm) were taken from the inferior alveolar nerve to the mesial and distal root apices. Subjects were grouped by age and gender. Data were analysed using two-w…
