Pautas de conducta frente a los pacientes bajo tratamiento anticoagulante en la clínica dental.

Nuestro trabajo pretende dar unas ideas básicas para el manejo de pacientes sometidos a tratamiento anticoagulante dando a conocer las posibles pautas a seguir respecto a su medicación: mantener intacta la terapia anticoagulante, modificar la terapia anticoagulante o realizar tratamiento combinado de heparina con anticoagulantes orales. La decisión deberá tomarse conjuntamente con el hematólogo responsable del paciente valorando cada caso según la morbilidad intrínseca de la intervención, el riesgo de tromboembolismo en función de la patología de base que presente el paciente y el grado de coagulación determinado mediante estudios de laboratorio (tiempo de protrombina e índice de trombotest).

Liberación de mercurio por parte de las obturaciones de amalgama dental: tipo, cantidad, método de determinación y posibles efectos adversos

Las obturaciones dentales de amalgama constituyen la fuente principal de exposición permanente de bajo nivel al vapor de mercurio (Hg°) y al mercurio inorgánico (Hg(II)) para la población general. La dosis de mercurio absorbido procedente de la amalgama es de 2.7 ¿g/día/persona para una cantidad promedio de 7.4 obturaciones. Si esta cantidad consistiera enteramente en mercurio inorgánico (Hg(II)), estaría muy por debajo de la cifra de 15 ¿g/día para una persona de 65 kg que la OMS considera como ingesta tolerable de mercurio inorgánico. En el caso de una exposición permanente a la misma cantidad, pero de vapor de mercurio (Hg0), se obtendría una concentración de 0.18 mg/m3 que puede compararse con la concentración de referencia de la EPA de 0.3 mg/m3 o con el nivel de riesgo mínimo de la ATSDR de 0.2 mg/m3. Varios estudios clínicos longitudinales y aleatorizados han evaluado la relación entre la concentración urinaria de mercurio y la exposición al mercurio procedente de las obturaciones dentales de amalgama en niños, particularmente vulnerables al Hg0, así como los posibles efectos neurológicos de tal exposición. La concentración promedio de mercurio en orina en los niños tratados con amalgama, con un promedio de 18,7 superficies obturadas, aumentó hasta un pico de 3.2 ¿g/L a los 2 años de iniciado el tratamiento y a los 7 años de seguimiento había descendido hasta los niveles basales y no se detectó ninguna alteración en las distintas exploraciones de monitorización neuropsicológica. De la misma manera, diversas investigaciones epidemiológicas no han aportado ninguna evidencia del papel de la amalgama en la posible causa o exacerbación de trastornos degenerativos como la esclerosis lateral amiotrófica, la enfermedad de Alzheimer, la esclerosis múltiple o el Parkinson. La extracción de las obturaciones de amalgama produce un aumento transitorio de los niveles de mercurio en sangre inmediatamente después de extraer las obturaciones de amalgama, pero de pequeña magnitud y que se normaliza a los 100 días, por lo que el efecto del dique de goma tiene una relevancia toxicológica menor. La conclusión de esta revisión es que la amalgama dental continúa siendo un excelente material de obturación.

Riesgo de transmisión de enfermedades infecciosas en la clínica dental

Se presenta en este artículo una revisión del riesgo de transmisión de enfermedades infecciosas en la clínica dental. Las hepatitis víricas, en especial la hepatitis B y la C, la infección por el virus de la inmunodeficiencia humana, la tuberculosis, y otras enfermedades infecciosas pueden ser potencialmente transmitidas en el ejercicio de la profesión, tanto a los pacientes como a los profesionales. El conocimiento de la probabilidad de transmisión y sus características son la base sobre la que desarrollarán las medidas preventivas de control de infección que intentan evitar o por lo menos minimizar la probabilidad de adquirir estas enfermedades en el ámbito laboral.

Utilité de la prophylaxie antibiotique avant un geste dentaire pour tes porteurs de prothèses totales du genou ou de la hanche [Antibiotic prophylaxis before dental procedures in arthroplasty patients]

Antibiotic prophylaxis is commonly prescribed to patients with total arthroplasties before a dental intervention. This attitude is not evidence-based for several reasons: 1) the usual pathogens of prosthetic joint infections are not of oral origin; 2) even if given, systemic antibiotic do not completely suppress the occult bacteraemia occurring during dental intervention and 3) humans may have up to twelve episodes of occult bacteraemia of dental origin per day. Routine antibiotic prophylaxis should be clearly distinguished from the antibiotic treatment required in case of established oral cavity infection. A constant optimal oral and dental hygiene is more important in terms of prevention and should be routinely recommended to every patient carrying a joint arthroplasty.

Rehabilitation of orbital cavity after total orbital exenteration using oculofacial prostheses anchored by osseointegrated dental implants posed as a one-step surgical procedure

BACKGROUND: Total orbital exenteration is a radical surgical procedure, which typically involves the removal of the entire contents of the orbit including the periorbita, leaving the patient with a deep orbital deformity and results in devastating cosmetic, functional, and psychological consequences requiring difficult and challenging procedures for oculoplastic surgeons. Oculofacial prostheses retained by endosseous dental implants present an attractive and viable alternative when aesthetic and functional demands are beyond the capacity of local reconstructive efforts. PATIENTS AND METHODS: A 72-year-old woman presenting a malignant melanoma of the right eyelids and a 77-year-old man presenting a sebaceous carcinoma of the left upper eyelid underwent a total exenteration followed by positioning of endosseous implants (Straumann system Dental implants) as an integrated one-step combined surgical procedure. The oculofacial prosthesis was placed after epithelialization of the orbital cavity. RESULTS: The implants were perfectly osseointegrated without any complications, providing sufficient retention of the prostheses. A satisfactory aesthetic outcome has been achieved for both patients. CONCLUSIONS: Oculofacial prostheses anchored by osseointegrated dental implants placed as one-step surgical procedure ensure an adequate aesthetic result as well as a considerably decreased rehabilitation time and present a satisfactory solution when reconstruction is not a suitable option.

An epidemiological study of dental agenesis in a primary health area in Spain: estimated prevalence and associated factors

Objectives: To evaluate the prevalence of dental agenesis and its possible association with other developmental dental anomalies and systemic entities. Setting and Sample Population: Descriptive transversal study, for which 1518 clinical records, of patients visited by the Odontological Service of the Primary Health Centre of Cassà de la Selva (Girona-Spain) between December 2002 and February 2006 were reviewed. The data were recorded in relation to the oral and dental anomalies and the associated systemic entities, between the ones referred as concomitant in literature. Results: Values of 9.48% (7.25% excluding the third molars) for dental agenesis and 0.39% for oligodontia were obtained. The presence of dental agenesis concomitant with some other forms of oral and dental anomalies was observed. Attention must be drawn to the fact that a greater number of concomitant systemic entities were observed in those patients that presented a severe phenotypical pattern of dental agenesis. Conclusions: The results of the present study do not differ from the ones reported in studies of similar characteristics among Occidental and Spanish populations. The relationship observed between certain systemic entities and developmental dental anomalies suggest a possible common genetic etiology
