The paper introduces a coverture based on a special compound resin, with a specifically treated filling as additive. The coverture can be applied for the treatment of pigmental tooth,for example, tetracycline tooth and fluorinated tooth. The coverture has such merits as good sticking and bio-inertia. The coverture applied to tooth is smooth, its colour artistic. Clinical application to some thousands of cases reveals satisfactory result.
