ABSTRACT

Introducción: La osteonecrosis en los maxilares por medicación es una afección asociada al tratamiento con bifosfonatos, antireabsortivos y antiangiogénicos. Objetivo: Caracterizar clínica y terapéuticamente los pacientes diagnosticados de Osteonecrosis en los Maxilares relacionada con medicación. Material y Método: Se realizó una serie de casos de 19 pacientes, la totalidad de los diagnosticados con la entidad en el Servicio de Cirugía Maxilofacial. Facultad de Estomatología Raúl González Sánchez, enero 2018-enero 2019. Se identificó severidad, factores de riesgo y se estandarizó tratamiento que incluyó la curación con aceite ozonizado y la aplicación de láser infrarrojo. Se evaluó el tratamiento a los 90 días. Se operacionalizaron las variables: sexo, tipo de medicación, vía y tiempo de administración, localización y evaluación al tratamiento. Resultados: La edad promedio de los pacientes fue 69±8,5 años, un 52,63 por ciento fueron masculinos, el zolendronato fue el agente mas asociado en el 78,95 por ciento de los casos, la enfermedad periodontal fue el factor local preponderante (57,89 por ciento), la localización mandibular postero lateral y el estadio evolutivo 2 predominaron en el 63,16 por ciento y 52,63 por ciento de las lesiones. El 78,94 por ciento de los casos presentó evolución satisfactoria a los 90 días. Conclusiones: La medicación con bifosfosfonatos parenterales predominantemente con el zolendronato, fue la causa principal de las osteonecrosis, las cuales prevalecieron en el sector postero lateral de mandíbula y con el estadio 2. La variante de tratamiento de curación con aceite ozonizado e irradiación con láser fue la más implementada. Los valores de lesiones resueltas y mejoradas a los 90 días fueron satisfactorios(AU)


Introduction: Medication-related osteonecrosis of the jaws is an affection associated with the treatment with bisphosphonates, antiresorptive agents or antiangiogenic medications. Objective: To perform a clinical and therapeutic characterization of patients with the diagnosis of medication-related osteonecrosis of the jaws. Material and Method: A case series of a total of 19 patients with the diagnosis of medication-related osteonecrosis of the jaws was carried out in the Department of Dental and Maxillofacial Surgery of ¨Raúl González Sánchez¨ Dental School of Havana from January 2018 to January 2019. The severity and risk factors were identified and the treatment including the healing with ozone oil and the application of infrared laser was standardized. The patients were evaluated in the 90 days after treatment. The operationalization of variables included: sex, type of medications, ways and time of administration, localization, and evaluation of treatment. Results: The average age of patients was 69±8,5 years and 52,63 percent of them were male. Zolendronate was the most associated agent in 78,95 percent of cases. Periodontal disease was the most identified local factor (57, 89 percent). The posterolateral area of the mandible and stage 2 disease evolution predominated in 63,16 percent and 52, 63 percent of lesions, respectively. Also 78, 94 percent of cases had a satisfactory evolution in the 90 days after treatment. Conclusions: The administration of intravenous bisphosphonates, particularly Zolendronate, was the main cause of osteonecrosis. These lesions were mainly located in the posterior lateral area of the mandible and presented stage 2 disease evolution. Healing with ozone oil and application of infrared laser was the most implemented alternative treatment. The values of resolved and improved lesions were satisfactory in the 90 days after treatment(AU)

ABSTRACT

The morbidity rate of medication-related osteonecrosis of the jaws (MRONJ) increased rapidly in recent years. Thusfar, the mechanism of MRONJ has no consensus. The possible mechanisms may include bone remodeling inhibition theory, angiogenesis inhibition theory, oral microorganism infection theory, immunosuppression theory, cytotoxicity-targeted oral epithelial cells, microcrack formation of maxillary or mandibular bone, and single nucleotide polymorphism. However, the efficacy of prevention and treatment based on a single mechanism is not ideal. Routine oral examination before MRONJ-related drug treatment, treatment of related dental diseases, and regular oral follow-up during drug treatment are of great significance for the prevention of MRONJ. During the treatment of MRONJ, the stage of MRONJ must be determined accurately, treatment must be standardized in accordance with the guidelines, and personalized adjustments must be made considering the specific conditions of patients. This review aimed to combine the latest research and guidelines for MRONJ and the experiences on the treatment of MRONJ in the Maxillofacial Surgery Department of West China Hospital of Stomatology, Sichuan University, and discuss the strategies to improve the clinical process.

ABSTRACT

La acción terapéutica favorable que los antirresortivos (bifosfonatos BPs, denosumab DS) y drogas antiangiogénicas ocasionan en el tejido óseo en aquellos pacientes que presentan como causa etiológica cáncer o discrasias óseas incluyen hipercalcemias malignas o ­si requieren el consumo de dicha droga a baja concentración­ como ser: osteoporosis, osteopenia, enfermedad de Paget, displasia fibrosa, Osteogénesis Imperfecta. (1) La presente actualización pretende relacionar el tratamiento odontológico con prescripción crónica y drogas antirresortivas, para lo cual American Association of Oral and Maxillofacial Surgeons AAOMS: define el concepto de Osteonecrosis Maxilar Asociada a drogas Antirresortivas (MRONJ) como: «Área ósea necrótica expuesta al medio bucal con más de ocho semanas de permanencia, en presencia de tratamiento crónico con bifosfonatos en ausencia de radioterapia en cabeza y cuello¼. La AAOMS estableció los siguientes grupos de acuerdo con sus características clínicas en 4 estadios (0, 1 ,2 y 3) de acuerdo con el aspecto clínico y radiológico de la lesión osteonecrótica. Estadío 0: lesión osteonecrótica sin evidencia de hueso necrótico en pacientes bajo consumo de drogas antirresortivas. Estadío 1: lesión osteonecrótica con signos clínicos y ausencia de sintomatología clínica. Estadío 2: lesión osteonecrótica con signo y sintomatología clínica evidente. Estadío 3: lesión osteonecrótica con signo y sintomatología evidente que compromete a estructuras nobles: fracturas patológicas, anestesia del nervio dentario inferior, comunicación buco-nasal, comunicación buco-sinusal, fístulas cutáneas (2) (AU)


It is known the favourable action which antiresorptive (Bisphosphonates BPs, Denosumab: DS) and Antiangiogenic drugs produce in bone tissue. High concentrations are primarily used as an effective treatment in the management of cancer-related disorders, including hypercalcemia of malignant. Besides, low concentrations are used for other metabolic bone diseases including Osteoporosis, Osteopenia, Paget's Disease, Fibrous Dysplasia, Imperfect Osteogenesis. (1) The update relate relationship between dentistry and chronic treatment with antiresorptive drugs. According to the American Association of Oral and Maxillofacial Surgeons (AAOMS), MRONJ is defined as exposed or necrotic bone in the maxillofacial region that has persisted for more than 8 weeks in association with current or previous BPs or DS therapy and with a lack of head and neck radiotherapy. AAOMS divided the MRONJ into 4 stages (0,1, 2 and 3) according to the clinical and radiological aspect of the osteonecrotic lesion: Stage 0: osteonecrotic lesion without sign-pathognomonic evidence of osteonecrosis. Stage 1: osteonecrotic lesion with clinical signs and absence of clinical symptoms. Stage 2: osteonecrotic lesion with sign and evident clinical symptoms. Stage 3: osteonecrotic lesion with signs and evident symptoms that involve noble structures: pathological fractures, anaesthesia of the lower dental nerve, oral-nasal communication, oral-sinus communication, skin fistulas (2) (AU)
