The purpose of this study was to evaluate the effectiveness of new commercially available glass ionomer cement (Fuji ionomer cement, type II) in treatment of cervical hypersensitive dentin and to estimate in vitro fluoride uptake in bovine dentin from the cement. The results obtained were as follows: 1. The cured cement discs released fluoride contained in the cement powder. 2. Freshly exposed bovine dentin applied with the cement for seven days in water, uptook more fluoride than dentin applied with carboxylate cement or intact dentin. 3. Application of the cement led to considerable reduction in hypersensitivity of dentin to cold, sweet and tactile stimuli over a month. Retention of the cement to the root surface is essential for successful treatment of hypersensitivity, because removal of the cement from root surfaces one month after application, resulted in recurrence of hypersensitivity. 4. The cement supplemented with aluminium fluoride or paraformaldehyde and non-supplemented one were similar both in clinical effectiveness in the treatment of hypersensitive dentin and in fluoride uptake in bovine dentin.
