The purpose of this study was to investigate the clinical effects of dentifrices containing TNA, ε-ACA, ALCA and α-Tocopherol, on periodontal heath. 54 female workers living in a dormitory(mean age: 22.2 years) were divided into 4 groups. Before the beginning of experimental periods scaling was performed on all subjects, and test and control dentifrices were supplied. The plaque index and gingival index were analysed after 1 week, 1 month and 3 months, respectively. The results were as follows: 1. Significant difference in plaque index between three test dentifrices and placebo dentifrice was not observed. 2. Gingival index reducing effects against control dentifrice of TNA, ε-ACA, ALCA, α-tocopherol and SMFP containing dentifrice, ε-ACA and ALCA containing dentifrice and TNA, ALCA, α-tocopherol and SMFP containing dentifrice were 22.4, 39.3 and 21.5% after 1 month. 3. Gingival index reducing effects against control dentifrice of TNA, ε-ACA, ALCA, α-tocopherol and SMFP containing dentifrice, ε-ACA and ALGA containing dentifrice and TNA, ALCA, α-tocopherol and SMFP containing dentifrice were 27.6, 59.2 and 52.4% after 3 month. 4. The clinical effects of three test dentifrices showed no statistical differences.
