Anestésicos locales en odontoestomatología

El motivo del presente trabajo es hacer una revisión bibliográfica sobre los anestésicos locales (AL) que son las drogas de más uso en Odontoestomatología y que, merced a su perfeccionamiento, en los últimos años han significado un enorme avance, tanto en los tratamientos odontológicos, para mejorar de forma determinante la operatoria dental, como el confort del paciente en estos procederes. Además al haber añadido a estos anestésicos locales un vasoconstrictor se ha conseguido que se puedan usar dosis menores de anestésico y a la vez que con menos dosis se puede actuar más tiempo y en buenas condiciones para el paciente y el dentista. Se realiza al mismo tiempo un estudio de las posibles interacciones medicamentosas, contraindicaciones, etc. de los distintos componentes de la solución anestésica, así como las posibles reacciones de alergia o de hipersensibilidad a la que puedan dar lugar y que se han de tener muy en cuenta a la hora de su utilización en la cavidad oral.The purpose of the present paper is to carry out a review of the literature on local anesthetics (LAs), which are the most commonly used drugs in dentistry. Thanks to their improvement over the last few years, they have constituted an enormous advance in both odontological treatment - improving the dental operation in a determinant manner, and the comfort of the patient during these procedures. Furthermore, the addition of a blood vessel constrictor to these local anesthetics has meant that a lower dose of anesthetic can be used, which at the same time acts for longer, providing better conditions for both the patient and dentist. In addition, a study is made of the possible drug interactions, contraindications etc. of the different components in the anesthetic solution, and likewise the possible allergic hypersensitive reactions which can take place and which must be taken closely into consideration when used in the oral cavity

The development of proliferative verrucous leukoplakia in oral lichen planus: a preliminary study

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 forms (n=4; 28.5%). Clinically it spread towards attached gingival mucosa and the hard palate. In the histopathologic study, there were a predominance of hyperkeratosis and verrucous epithelial hyperplasia. Three of the cases progressed to a squamous cell carcinoma, and one patient developed two verrucous carcinoma. Conclusions: Further research is needed to demonstrate if proliferative multifocal oral lichen planus and proliferative multifocal oral leukoplakia are the same disorder but have different behaviour of malignancy for reasons of origin
