Polishing-Paste-Induced Silica Granuloma of the Gingiva

Abstract

Polishing-paste-induced silica granuloma of the gingiva, an uncommon condition, may mimic various local or systemic pathological entities. A 33-year-old woman and a 42-year-old man were referred for a localised refractory gingival inflammation. Clinical diagnoses included allergy, lichen planus and herpes. Biopsy showed well-demarcated non-caseating granulomas, associating epithelioid and Langhans giant cells. Special bacterial and mycological stains were negative. Systemic examination and laboratory tests ruled out sarcoidosis and Crohn’s disease. Polarised light revealed birefringent crystalline foreign material. A diagnosis of silica granuloma was made. Both patients had frequent dental hygiene treatment including polishing with abrasive paste, suggesting an iatrogenic implantation of the foreign bodies. Gingival damage can result from the use of some dental materials containing silica. Often asymptomatic, sometimes producing visible lesions, granulomatous gingivitis may mislead into wrong diagnosis and treatment. Old silica granulomas may become symptomatic if the patient contracts sarcoidosis.

Orofacial granulomas after injection of cosmetic fillers. Histopathologic and clinical study of 11 cases

“…This latter lesion often results from a past accidental inclusion of soil particles in a wound, in which case the granulomatous reaction around birefringent crystals is embedded in scar tissue (15, 25±27). A more rare possibility is the accidental inclusion of silica or silicate-containing dental products in oral tissues during dental care (28). The clear vacuolated macrophages of Liquid silicone granuloma in case of scarce microcysts might be overlooked and easily mistaken as adipocytes, and at casual examination, the lesion might be misdiagnosed as sclerosing lipogranuloma (11).…”

A case of implantation dermatosis that formed a tumor

“…In 66 papers, the lesions were iatrogenic (including both medical and non‐medical procedures) foreign body reactions. Another 44 cases in nine papers 11–19 were reported as ID cases. The foreign materials discovered in the cases were a wood fragment, 11 sea urchin, 12 silica, 14,16 pencil‐core, 18 oil 19 and others 13,15,17 .…”

Rebuilding Anterior Dental Esthetics: Interdisciplinary Treatment of an Iatrogenically Induced Marginal Tissue Recession

“…Clinical dental experience plays a pivotal role in improving the quality of patient care and satisfaction. However, iatrogenic injuries during dental treatments may occur in daily practice 1‐7 . Root canal perforation during endodontic therapy is one of the most commonly encountered clinical situations that necessitates an interdisciplinary therapy in some severe cases.…”

“…However, iatrogenic injuries during dental treatments may occur in daily practice. [1][2][3][4][5][6][7] Root canal perforation during endodontic therapy is one of the most commonly encountered clinical situations that necessitates an interdisciplinary therapy in some severe cases. Although size and location of the perforation, its immediate sealing, and prevention of infection are the main factors that affect the success of endodontic therapy, 8 the biotype of the gingiva, the amount of exposed root surface, and the material used for sealing the perforation are additional critical determinants that need to be considered from a periodontal point of view.…”
