title: Ultrastructure of gingival sulcus mucosa after application of hybrid heliocomposites.
abstract: Hybrid heliocomposites were used for repair of the carious tooth crown. Ultrastructural study of mucosa biopsy specimens from sites adjacent to the filling 3 weeks after treatment showed that Charisma, Herculite, and Esterfil Ca filling materials led to degenerative changes in the mucosa, while Filtek Z-250 heliocomposite caused no pathological changes in the gingiva at the site of contact.
