Regeneración periodontal en defectos intraóseos de 2-3 paredes con tres membranas diferentes: Un ensayo clínico randomizado
Enrile de Rojas,Francisco J.; Buitrago-Vera,Pedro J.; Sicilia-Felechosa,Alberto; Tejerina-Lobo,José Ma;
RCOE , 2006, DOI: 10.4321/S1138-123X2006000100002
Abstract: background: a study is made to evaluate the clinical efficacy, in terms of clinical attachment gained, of two resorbable membranes versus a positive control (non-resorbable membrane), in the treatment of two-three wall intrabony defects. patients and method: we selected 36 patients in whom 43 two-three wall intrabony lesions were detected. prior to surgery we recorded pocket depth and gingival recession (clinical attachment level). after a full thickness flap approach, debridement and measurement of the defects, and instrumentation of the root wall, the membrane was placed. clinical follow-up was carried out after 1, 2, 4, 6 and 8 weeks, and 3, 6 and 12 months, with radiological controls after 6 and 12 months. results: a total of 36 defects completed the study, corresponding to 30 patients. after one year a mean reduction in pocket depth of 3.98 mm was recorded, with a 0.17 mm recession increment and a clinical attachment gain (nci) of 3.97 mm. no significant differences were observed between the different membranes used.
Tomografía computerizada: introducción a las aplicaciones dentales
Arana-Fernández de Moya,Estanislao; Buitrago-Vera,Pedro; Benet-Iranzo,Francisco; Tobarra-Pérez,Eva;
RCOE , 2006, DOI: 10.4321/S1138-123X2006000300003
Abstract: introduction and goals: the increasing complexity of dental techniques has been correlated with increased diagnostic accuracy. dental implantology development has placed computed tomography (ct) as the first diagnostic tool in treatment planning. our aim is to explain the capabilities and features of ct imaging in order to allow dentists to take informed decisions and integrate this technique into their work.. also, they must know ct diagnostic capabilities in their referrals. objectives: the aim of this paper is to show the surgical technique used. besides, the indications, contraindications and complications are described. material and method: by means of a review of the most updated and didactic literature, we describe the current indications of ct in the field of dentistry. finally, we will explain ct technology and the different kind of images obtained. the article is structured as follows: indications, ct technology, geometric considerations and image reconstruction techniques. this comprises surface rendering, maximum intensity, volume rendering and multiplanar reformatting. results: detailed exposition by means of pictures of the different kind of images obtained by ct, according to the reconstruction techniques used.
Regeneración periodontal en la practica clínica

Abstract: the regeneration or restitution of lost supporting tissue has always been considered the ideal objective of periodontal therapy. however, attempts to convert this intention into solid clinical practice can become tremendously complex, the results of which are very different from the original intention. the aim of this article is to offer an up-to-date, general perspective on periodontal regeneration, orienting the clinician within the global strategy for oral treatment. to this end, we revise the healing process of periodontal injury, the different therapeutic approaches, the interpretation of the results, and finally, limiting factors in periodontal regeneration.
Electromagnetic Force as consequence of the Geometry of Minkowskian Spacetime
J. Buitrago
Physics , 2009,
Abstract: By describing the dynamical evolution of a test charged particle in the presence of an electromagnetic field as a succession of infinitesimal Lorentz boosts and rotations it is possible to obtain the Lorentz Force of Electrodynamics. A consequence of this derivation at the classical level is that, given the existence of electric and magnetic fields, the form of the electromagnetic force acting on the particle can be regarded as arising from the geometry of Minkowskian spacetime.
LA POLíTICA DE SEGURIDAD DEMOCRáTICA 2002-2005
Leal Buitrago,Francisco;
Análisis Político , 2006,
Abstract: this article shows the evolution of security -related policies formulated during alvaro uribe's presidency (2002-2006) through the end of 2005. the policy of democratic security was implemented along three lines. first, the continuation of the military offensive against the farc which was started by the previous government. this offensive has been possible thanks to u.s. aid and was revamped with the more sophisticated plan patriota, operating mainly in the southern part of the country where the strategic rearguard of the farc is located. second, a "policy of peace" with the paramilitary, which has been complex due to the difficulties of promoting a law that permits minor punishments for the authors of war crimes and international humanitarian law violations. and third, a series of specific measures -such as peasant soldiers, desertion incentives, and informant networks- destined to strengthen the other two. these policies have had ambivalent results, just as the entire security policy more generally. the chapter ends with the uncertainty generated by the informal beginnings of the electoral process at the end of 2005, which incorporate security concerns and conditions security policies in the future.
