ABSTRACT
Foreign body impactions can be frequently seen in childhood as children have a habit of putting different objects in the mouth. These impacted foreign bodies if not removed timely, at times can lead to severe reactions leading to granuloma formation. A simple injury, if ignored, can result in severe damage to oral tissue and even loss of the permanent tooth. Therefore, all penetrating injuries should be carefully assessed and treated timely. This study describes a rarest intraoral case of pencil core granuloma with retained graphite lead inside it that led to severe tissue reactions. Pencil core granuloma has been reported extra orally and on limbs. This case report describes the rarest case reported intraorally.
ABSTRACT
Plasma cell granuloma is a rare benign lesion characterized by the infiltration of plasma cells; primarily occurring in the lungs. It is also seen to occur in the brain, kidney stomach, heart, and so on but its intraoral occurrence is a rarity. This case report represents one of the uncommon locations in the oral cavity affected by plasma cell granuloma, its clinical and histological features, and establishes the differential diagnosis with other malignant or benign disease entities and planning the treatment accordingly. This report discusses the diagnostic enigma and the associated terminology of plasma cell granulomas and reinforces the need for performing biopsy and a histopathological or immune histochemical study, irrespective of the clinical features and clinical diagnosis of the lesion. In this case a 52-year-old female, presented with gingival enlargement in the mandibular anterior region, treated by excisional biopsy. Histological evaluation revealed plasma cell infiltrates in the connective tissue. The immune-histochemistry revealed kappa and lambda light chains with a polyclonal staining pattern, which confirmed the diagnosis of plasma cell granuloma.
ABSTRACT
BACKGROUND AND OBJECTIVES: The pathogenesis of inflammatory periodontal diseases essentially involves degradation of extracellular matrix molecules, and collagen breakdown and matrix metalloproteinases (MMPs) are proteinases primarily involved in this process. It is known that doxycycline downregulates MMP activity. Curcumin has anti-inflammatory effect and also downregulates MMP activity. Thus, a study was conducted to evaluate the anti-inflammatory effect of curcumin by its inhibition of MMP-9 activity and compare the same with doxcycline, which has known anticollagenase activity. SUBJECTS AND METHODS: Gingival tissue samples were obtained from thirty patients diagnosed with chronic periodontitis. The tissue extracts were treated with Curcumin and doxycycline and inhibition of MMP-9 analyzed by gelatinzymography. Gels obtained were stained with Coomassie Brilliant Blue, and enzymatic activities detected as bands of gelatinlysis against blue background. Relative MMP-9 levels were measured by scanning the clear zones and analyzing the percentage inhibition. RESULTS: Results showed that MMP-9 activity was significantly decreased by both the drugs. Curcumin showed 61.01% reduction in the MMP-9 activity at 1500 µg/ml concentration and doxycycline showed 59.58% reduction in the MMP-9 activity at 300 µg/ml concentration. CONCLUSION: The current study showed that curcumin has inhibitory effect on polymorphonuclear leukocyte-type MMP-9 involved in matrix degradation in periodontitis. Since Curcumin has a potent anti-inflammatory effect, it may have therapeutic potential as a host modulation agent in periodontal diseases.
