ABSTRACT
Orofacial granulomatosis (OFG) is an uncommon clinicopathological condition describing patients who have oral lesions characterized by persistent labial enlargement, oral ulcers and a variety of other orofacial features. Sarcoidosis is a systemic non-caseating granulomatous disorder of unknown etiology that may affect multiple organ systems. As a systemic disease, it is well documented in existing literature. However, the rarity and its often non-specific oral manifestation emphasize the need to reinforce the literature with more clinical case examples and draw additional attention to clinical features that general practitioners may encounter. In this report, a rare case is presented with definite association of sarcoidosis and orofacial granulomatosis with two years follow up after treatment. This report aims to expand the literature surrounding orofacial sarcoidosis and support oral and general health practitioners in recognizing its orofacial manifestations along with the clinical presentations that all led to a diagnosis of sarcoidosis in this case.
ABSTRACT
BACKGROUND: The outcome of periodontal regenerative therapy depends upon the of the biocompatibility root surfaces to the regenerating periodontal tissues. This in vitro scanning electron microscopic (SEM) study was designed to evaluate and compare the demineralizing efficacy of ethylene diamine tetra acetic acid (EDTA), with that of tetracycline hydrochloride applied on to the mechanically treated root surfaces of periodontally involved tooth. METHODS: Forty specimens were prepared from teeth extracted due to advanced periodontal disease and divided into two groups. The study group was treated with an EDTA solution (pH 7.4) and the control group was treated with a tetracycline hydrochloride solution (pH 1.8). The photomicrographs obtained were assessed for presence of smear layer, number of exposed dentinal tubules, area occupied by tubule orifices along with intertubular surface appearance. The results thus obtained were analyzed statistically. RESULTS: Both EDTA and tetracycline were effective in removing the smear layer and the exposure of the number of dentinal tubules. The diameters of the tubules and thereby the surface area occupied by the tubule orifices in the EDTA treated group were significantly greater than the tetracycline HCL treated group (p < 0.05). CONCLUSION: The EDTA produced better effects than tetracycline by providing more demineralized area and collagen exposure at a neutral pH.
