The development of proliferative verrucous leukoplakia in oral lichen planus: a preliminary study
2016
Background: Was to describe 14 cases of a proliferative verrucous leukoplakia as a clinical evolution of oral lichen planus. Material and Methods: The clinical and histopathological characteristics of 14 cases of OLP that progress towards a plaque-like and verrucous form were indicated, with monitoring over a period of six to 24.3 years. Results: The female/male ratio was 11/3, (78.6 and 21.4%). The mean age when the first biopsy was undertaken was 56.4 years old. None of the patients smoked during the study. As bilateral reticular was clinically diagnostic criterion, the second most frequent clinical form was the plaque form (n=10; 71.4%), followed by the atrophic (n=6; 42.8%), and erosive…
Taurodontism: a review on its etiology, prevalence and clinical considerations
2010
Taurodontism can be defined as a change in tooth shape caused by the failure of Hertwig’s epithelial sheath diaphragm to invaginate at the proper horizontal level. An enlarged pulp chamber, apical displacement of the pulpal floor, and no constriction at the level of the cemento-enamel junction are the characteristic features. Although permanent molar teeth are most commonly affected, this change can also be seen in both the permanent and deciduous dentition, unilaterally or bilaterally, and in any combination of teeth or quadrants. Whilst it appears most frequently as an isolated anomaly, its association with several syndromes and abnormalities has also been reported. Despite the clinical c…
Reacción liquenoide oral en relación con una restauración de amalgama de plata

La amalgama de plata es uno de los materiales de uso odontológico, frente al que se pueden producir reacciones de hipersensibilidad. La forma más frecuente es la aparición de una reacción liquenoide, que afecta a la mucosa oral en contacto directo con la restauración de amalgama y que está producida por una reacción de hipersensibilidad retardada tipo IV, como respuesta inmune mediada por células frente al mercurio o a algún otro componente de la amalgama dental. En este trabajo presentamos un caso de reacción liquenoide oral (RLO) asociada a una restauración de amalgama de plata.

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…

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.

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.

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.

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 …
