Consensus statement on antimicrobial treatment of odontogenic bacterial infections.

The infection of the oral cavity is a common public health problem and constant cause for antibiotic prescription, with 10% of antibiotics used to treat this problem. However, few studies have so far aimed to determine its incidence. Added to this, its relationship with certain sytemic diseases (cardiac, endocrine, etc) confers this pathology vital importance. In spite of the frequency and importance of odontogenic infection, the current dispersion in criteria regarding key aspects in classification, terminology and therapeutic recommendations is noticeable. The main objective of this document, compiled as a consensus statement by specialists in microbiology and odontology, is to establish useful recommendations for all of those involved in the clinical management of this pathology. Special attention has been placed on the rise in bacterial resistance observed over the last years, specifically the proliferation of betalactamase producing strains. Another important factor causing the resistance to appear is lack of therapeutic compliance, specially what regards dosage and treatment duration. Therefore, this pathology constitutes a complex problem which requires the instauration of broad spectrum antimicrobials, well tolerated and a convenient posology so that patients receive the adequate dose over the necessary period. High doses of amoxicillin/clavulanate (2000 mg/125 mg) have showed good results and power to overcome resistance. Other agents such as metronidazole and clindamycin, followed by de claritromycin and azithromycin have also proved to be active against most of microorganisms responsible for odontogenic infection.

Documento de consenso sobre el tratamiento antimicrobiano de las infecciones bacterianas odontogénicas / Consensus statement on antimicrobial treatment of odontogenic bacterial infections

Las infecciones de la cavidad bucal son un problema de salud pública frecuente y motivo constante de prescripción antibiótica; el 10% de los antibióticos se emplean para tratar este problema. Sin embargo, hasta la fecha son pocos los estudios realizados para determinar su incidencia. Asímismo, su relación con ciertas enfermedades sistémicas (cardiacas, endocrinas, etc...) confiere a estas patologías una importancia vital. A pesar de la reconocida frecuencia e importancia de las infecciones odontogénicas, llama la atención la actual dispersión de criterio en varios aspectos referentes a su clasificación, terminología y recomendaciones terapéuticas. El objetivo principal de este documento, realizado con el consenso de especialistas en microbiología y odontología, es establecer unas recomendaciones útiles para todos los profesionales implicados en el manejo clínico de estas patologías. Recibe especial atención el aumento de la prevalencia de resistencias bacterianas observado durante los últimos años y, en concreto, la proliferación de cepas productoras de betalactamasas. Otro factor causal importante de la aparición de resistencias es la falta de cumplimiento terapéutico, en especial en lo que respecta a la dosis y a la duración del tratamiento. Así pues, estas patologías constituyen un problema complejo cuyo abordaje requiere la instauración de antimicrobianos de amplio espectro, con adecuados parámetros farmacocinéticos, con buena tolerancia y una posología cómoda que permita que el paciente reciba la dosis adecuada durante el tiempo necesario. Amoxicilina/ácido clavulánico a dosis altas (2000mg/ 125mg) ha demostrado buenos resultados y capacidad para superar resistencias. Otros agentes como metronidazol y clindamicina, seguidos de claritromicina y azitromicina han demostrado también ser activos frente a la mayoría de los microorganismos responsables de las infecciones odontogénicas (AU)

Infecciones orofaciales de origen odontogénico / Orofacial infections of odontogenic origin

La naturaleza polimicrobiana de las infecciones odontógenas así como la heterogeneidad de los cuadros clínicos asociados son consecuencia de la diversidad de la microbiota bucal y de la complejidad anatómica y funcional de la cavidad oral. Así mismo, estos procesos pueden dar lugar a múltiples complicaciones que pueden limitarse a afecciones locales o derivar hasta compromisos sistémicos. En el tratamiento farmacológico de estas infecciones es crucial la elección del antibiótico y la pauta posológica más eficaces. La farmacodinamia proporciona los parámetros que hacen posible valorar como varía la actividad de los antibióticos en función del tiempo. Como norma general, en el manejo inicial de las infecciones orofaciales en el adulto, incluidas las infecciones odontógenas, se utilizará amoxicilina/ac. Clavulánico en dosis de 875 mg de amoxicilina y 125 mg de ac. clavulánico pautado cada 8 horas. El cumplimiento terapéutico es clave para evitar la aparición de resistencias, por lo que se ha de maximizar la aceptación por parte de los pacientes. En este sentido se ha demostrado que la nueva presentación de 2000/125 mg de Augmentine Plus pautado cada 12 horas tanto en profilaxis como tratamiento disminuye significativamente la tasa de complicaciones infecciosas derivada de la extracción del tercer molar (AU)

The polymicrobial nature of the odontogenic infections as well as the variety of associated conditions are a consequence of the diversity of the buccal microbiota and the anatomical and functional complexity of the oral cavity. In addition to this, all these processes can give way to multiple complications which range from the local to the systemic level. The appropriate choice of antibiotic and posology is crucial in the successful management of these infections. Pharmacodyna-mics provides those parameters that make it possible to assess how antibiotics activity varies in time. As a general rule, the first step in the initial management of orofacial infections in adults, included odontogenic infections, will be the administration of 875 mg of amoxicillin and 125 mg of clavulanic every 8 hours. Therapeutic compliance is paramount to avoid resistance, therefore patient's acceptance must be sought. In this sense, it has been proved that Augmentine Plus (2000/125) every twelve hours both as profylaxis and as treatment significantly decreases the rate of infective complications associated to extraction of the third molar (AU)
