| Popis: | The pathogenic relationship between the oral lichenoid reaction and dental restorative materials has been confirmed many times. Lichen planus-like lesions (2) (oral lichenoid lesion,oral lichenoid reaction) can be caused by hypersensitivity to materials for dental restorations. The aim of this study is to determine the effect of restorative dental materials removal on the lichenoid reaction development. In this case report we present two male patients who were referred to the Department of Oral Diagnostics and Maxillofacial Radiology, at the Faculty of Dental Medicine, Medical University Sofia. Both patients had lesions located on the tongue and buccal mucosa. The routine examinations together with patch tests for dental allergy were used. The patients showed hypersensitivity to Nickel (Ni), Cobalt (Co), Amalgam and Mercury (Hg). Removal of the positively reacting materials followed by new hypoallergenic restorations led to spontaneous healing. The results have shown that the removal and replacement of these restorative materials do lead to remission of the symptoms and full healing of the oral lichenoid lesions. Close association between the lesion development and the dental materials which gave positive patch tests reaction was confirmed. A replacement of the problem causing restorations with hypoallergenic materials proved to be the reliable method for controlling the clinical symptoms and also led to a state of total healing of these two patients. |
