Signs of Combination Syndrome and removable partial denture wearing
Introduction:Combination Syndrome (CS) is a pathological condition observed in maxillary complete denture (CD) and mandibular removable partial denture (RPD) wearers.Purpose:The aim of this study was to observe and measure the prevalence of CS signs in treatment-seeking wearers of maxillary CD associated or not with RPD (mandibular Kennedy Class I). The association between RPD wearing and the number of CS clinical signs was also evaluated.Material and method:The sample included 62 patients seen at the Department of Dentistry, Federal University of Rio Grande do Norte (UFRN). A clinical oral examination was conducted to assess the presence of specific clinical signs of CS as described by Kelly (1972): bone resorption in the maxillary anterior region, tuberosity overgrowth, palatal papillary hyperplasia, extrusion of mandibular anterior teeth and bone resorption in the mandibular posterior region. The chi-square test at the 95% level of significance was used to test the association between dependent and independent variables.Result:Mandibular resorption was the most frequent complication (93.5%). There was a statistically significant difference between RPD wearers and non-wearers with regard to extrusion of mandibular anterior teeth (p = 0.045).Conclusion:Within the limitations of the present study, a high prevalence of CS clinical signs was observed, but no association between RPD wearing and syndrome characteristics was found
Fibrolipomatous hamartoma in a patient with tuberous sclerosis: Report of a case
Tuberous sclerosis is a rare congenital disorder with an incidence of 1 in 6000 births. The classic triad is seizure, mental deficiency, and angiofibromas. Orofacial manifestations include fibrous hyperplasia, hemangioma, bifid uvula, cleft lip and palate, macroglossia, high arched palate, and enamel defects. Benign tumors of the jaws including desmoplastic fibroma, calcifying odontogenic tumor, and odontogenic myxoma have been recently reported in tuberous sclerosis. This case report adds fibrolipomatous hamartoma of the mandible to this list

Solitary Plasmacytoma of the Mandible: An Uncommon Entity
Introduction: Plasma cell dyscrasias are characterized by a monoclonal neoplastic proliferation of plasma cells. Solitary bone plasmacytoma (SBP) is a local form of the disease with the vertebrae and long bones being the most frequently encountered sites. Its prevalence in the maxillofacial area is extremely rare.
Case Presentation: A 70-year-old Caucasian male patient was referred for the extraction of his mobile premolar tooth with a poorly-defined radiolucent lesion. Histopathological analysis revealed an SBP and no distant lesion or serum M protein was noted on radiological and hematological examinations. The patient was under follow-up care with no recurrence at 2 years of follow up.
Conclusions: Diagnosis of an SBP is based on local radiological and neurological symptoms and similar systemic manifestations of multiple myeloma that are also distinctive for SBP. Skeletal radiological analysis including CT and PET-CT, bone marrow biopsy, and serum protein electrophoresis are essential for confirmation of the diagnosis. Although surgery, chemotherapy, and radiation, or a combination of these modalities, have been successfully used in the treatment of SBP, it should be managed in relation to its possible long-term evolution
