Correlation with Caries Lesion Depth of The Canary System, DIAGNOdent and ICDAS II.

Introduction: The aim of this study was to correlate lesion depth of natural caries, measured with Polarized Light Microscopy (PLM), to Canary Numbers (CN) derived from The Canary System™ (CS), numerical readings from DIAGNOdent (DD), and lesion scores from ICDAS II.

Methods: A total of 20 examination sites on extracted human molars and premolars were selected. The selected examination sites consisted of healthy and enamel caries on smooth and occlusal surfaces of each tooth.

Evaluation of nanohydroxyapatite-containing toothpaste for occluding dentin tubules.

Purpose: To compare dentin tubule occlusion by dentifrices containing either nanohydroxyapatite (10%nHAP and 15%nHAP), sodium monofluorophosphate (Na-MFP) or NovaMin (NovaMin).

Methods: All 80 participants wore four intraoral appliances bearing dentin blocks while using one of the four test dentifrices (n = 20/dentifrice) twice daily for 14 days. The four appliances were removed in pairs after 7 and 14 days.

Effect of theobromine-containing toothpaste on dentin tubule occlusion in situ.

Objectives: Dentin hypersensitivity (DH) is treated by either occlusion of dentin tubules or nerve desensitization. This in situ study compared dentin tubules occlusion by theobromine-containing dentifrices with (Theodent-classic-F®, TCF) and without (Theodent-classic®, TC) fluoride with 1,500 ppm fluoride toothpaste, Colgate®-Regular (Fluoride) and Novamin®-containing toothpaste, Sensodyne®-5000-Nupro (Novamin®).

Methods: Each subject wore four intraoral appliances bearing dentin blocks while using one of four test dentifrices (n = 20/dentifrice) twice daily for 7 days.

In situ remineralization of white-spot enamel lesions by 500 and 1,100 ppm F dentifrices.

The aim of this study was to evaluate the remineralization potential of three silica-containing NaF dentifrice systems in an intraoral model. Subjects (N = 30) in this randomized, three-phase, 28-day, crossover study served as their own control. Each participant wore a customized orthodontic appliance attached to a mandibular molar and contained one tooth block with caries-like lesion.

Remineralization of eroded enamel by a NaF rinse containing a novel calcium phosphate agent in an in situ model: a pilot study.

Purpose: An in situ study evaluated the remineralization potential of 225 ppm fluoride (F) rinses with and without a calcium phosphate agent (TCP-Si-Ur) on eroded enamel.

Methods: 20 human patients participated in this IRB approved study. Enamel blocks extracted from 20 human molars were assigned to each of the three study phases (G1, G2, G3).
