Abstract
Non-secretory multiple myeloma (NSMM) is a rare cancer of plasma cells characterized by the absence of detectable monoclonal M protein in the blood or urine. A 57-year-old woman presented with mandibular pain but without intraoral swelling. Imaging studies revealed multiple osteolytic lesions in her mandible and pronounced root resorption of the left mandibular second molar. Biopsy results showed atypical plasmacytoid cells positive for anti-kappa, CD138, MUM1, and CD79a antibodies, but negative for anti-lambda and CD20. These results were indicative of a malignant plasma cell neoplasm. No abnormalities were revealed by free light chain assay or by serum or urine protein electrophoresis, leading to a diagnosis of NSMM. The patient began chemotherapy in conjunction with bisphosphonate therapy and achieved remission following treatment. This case underscores the critical role of dentists in the early detection and prevention of NSMM complications, as the disease can initially present in the oral cavity.

Abstract
This article discusses the orofacial clinicoradiographic features of systemic diseases that manifest in the orofacial region. The systemic diseases discussed are grouped into the following: autoimmune diseases, endocrine diseases, bone diseases, hematologic diseases, syndromes, and malignancies. The radiographic manifestation ranges from radiolucent bony destruction, increased bone density, calcification, thinning of cortical plate, loss of trabeculation, missing teeth, and supernumerary teeth. It is imperative for clinicians to be cognizant of these findings, as they may be the first manifestation of these systemic diseases.

Abstract
Introdução: O mieloma múltiplo e caracterizado como uma neoplasia maligna plasmocitária com a proliferação anormal de plasmócitos clonais na medula óssea de etiologia desconhecida. Objetivo: Caracterizar os pacientes com mieloma múltiplo atendidos no Setor de Estômato-Odontologia e Prótese do INCA, por meio de dados sociodemográficos, clínicos, laboratoriais e radiográficos. Método: Estudo transversal retrospectivo de pacientes com diagnostico de mieloma múltiplo, no período de 2000 a 2018, que realizaram radiografia panorâmica no período do diagnóstico da doença. Os dados sociodemográficos e clinico-radiográficos da população em estudo foram coletados nos prontuários dos pacientes, armazenados em banco de dados, analisados de forma descritiva e submetidos ao teste não paramétrico X2 (qui-quadrado). Resultados: Na amostra final, foram totalizados 163 casos. A maioria era de homens (56,4%), brancos (55,8%), com idade ≤55 anos (54%), ensino fundamental incompleto (30,7%), não fumantes (54,6%) e não bebedores (54,6%). Havia lesões líticas em 46 pacientes (28,2%) com predileção pela mandíbula (82,6%; p=0,000). Houve maior frequência de margens parcialmente definidas (50,0%), não escleróticas (78,2%) e de aspecto unilocular (43,5%). Dos 46 pacientes que apresentaram lesão lítica maxilomandibular, 27 pacientes tinham >55 anos (p=0,042). Conclusão: Ha maior ocorrência de lesões ósseas na mandíbula quando comparada a maxila.
