PURPOSE To compare the relative plaque control efficacy of a marketed 0.454% stabilized stannous fluoride (SnF2) dentifrice relative to a triclosan/copolymer dentifrice using digital plaque imaging analysis (DPIA). METHODS This was a randomized, two-treatment, double-blind, parallel group design study that compared SnF2 and triclosan/copolymer dentifrices over a period of 3 weeks. DPIA was us...

This study quantified alterations in root dentin permeability after exposure to different acid beverages. Twenty-five third molars were sectioned below the cementoenamel junction, the root segment was collected, and the pulp tissue was removed. The root segments were connected to a hydraulic pressure apparatus to measure the permeability of root dentin after the following sequential steps, with...

The aim of this study was to determine the efficacy of rinses with slurries of a dentifrice containing triclosan (TCS), as compared with rinses with slurries from a control dentifrice, in controlling early subgingival biofilm formation. A double-blind, randomized and cross-over clinical trial was designed, and 26 dental students were included. In the first period, participants were randomized t...

The objective of this study was to evaluate in vitro the effect of a low fluoride toothpaste (450 µgF/g, NaF) combined with calcium citrate (Cacit) and sodium trimetaphosphate (TMP) on enamel remineralization. Bovine enamel blocks had the enamel surface polished sequentially to determine the surface hardness. After production of artificial carious lesions, the blocks selected by their surface h...

BACKGROUND Human endeavors to prevent dental caries have led to the use of different modalities and agents, the most commonly used of which is fluoridated dentifrice. An in situ study was carried out to evaluate the efficacy of fluoridated dentifrices in achieving remineralization of initial caries-like lesions using surface microhardness measurements and to study the qualitative changes by sca...

Plasma cell gingivitis is a rare benign condition of the gingiva of unknown etiology characterized by sharply demarcated erythematous and edematous gingiva often extending to the mucogingival junction. This is sometimes considered as a hypersensitive reaction. It presents clinically as a diffuse, erythematous and papillary lesion of the gingiva, which frequently bleeds with minimal trauma. The ...
