Based on natural principles, we developed a novel toothpaste, containing morphogenetically active amorphous calcium polyphosphate (polyP) microparticles which are enriched with retinyl acetate (“a-polyP/RA-MP”). The spherical microparticles (average size, 550 ± 120 nm), prepared by co-precipitating soluble Na-polyP with calcium chloride and supplemented with retinyl acetate, were incorporated i...

OBJECTIVE To estimate the effect of arginine-containing desensitizing toothpaste on dentin hypersensitivity (DH). METHODS Databases including China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, China Biology Medicine disc, Wangfang Data, PubMed, Web of Science, and Cochrane Trials Register were searched, and Google was used as a supplementary tool to searc...

OBJECTIVES To evaluate the influence of different whitening protocols on the efficacy of 35% hydrogen peroxide (HP) tooth whitening and gel pH and concentration. MATERIAL AND METHODS Eighty-four enamel/dentin discs from bovine incisors were used. The baseline color was measured with a spectrophotometer. Two sessions of in-office whitening with 35% HP were performed under different protocols: ...

OBJECTIVE This study examined whether an ultraviolet light enhanced the whitening efficacy of a peroxide gel containing a photo-Fenton activator. METHODOLOGY Fifty subjects were enrolled into the trial at two geographically separate sites. As directed by the randomization keys, teeth of half of the study subjects were concurrently exposed to the whitening lamp, while the gel was on their teet...

Convolutional autoencoders (CAEs) are unsupervised feature extractors for high-resolution images. In the preprocessing step, whitening transformation has widely been adopted to remove redundancy by making adjacent pixels less correlated. Pooling is a biologically inspired operation to reduce the resolution of feature maps and achieve spatial invariance in convolutional neural networks. Conventi...

Objective: To evaluate the remineralization effects of the casein phosphopeptide-amorphous calciumphosphate (CPP-ACP) paste on the white spot lesions (WSLs) of the primary teeth thereby to assess its caries-prevention efficacy on early childhood caries (ECC) in vivo. Methods: A total of 11 high caries risk children with 36 noncavitated caries on smooth surfaces in primary incisors and canines w...

Toothpaste is a gel dentifrice used with a toothbrush as an accessory to clean, keep and promote oral hygiene. The literature review suggests that there are many different formulations of toothpastes and that each of their individual components present specific functions. The concentration of the toothpaste ingredients must be appropriately chosen taking into account the purposes of the toothpa...

The aim of this randomised, parallel, double-blind study, in which 28 adult patients diagnosed with chronic gingivitis or early stages of chronic periodontitis were recruited, was to evaluate the efficacy of 'Gamadent' toothpaste compared to a placebo toothpaste. 'Gamadent' toothpaste has all the basic constituents of a toothpaste with the addition of a sea cucumber extract (SCE) of the species...

objective: the main purpose of this study was to develop a simple reproducible system to compare abrasive effects of three different toothpastes. materials and methods: a specific mold was used to fabricate 37 samples made of po-lymethylmethacrylate. the samples were stroke by toothbrushes connected to a v8 cross brushing machine in a solution of fluoridated toothpastes and distilled water. the...

UNLABELLED The success of an esthetic rehabilitation depends on the understanding of the patient's need and expectation. The management of patients with moderate to severe tetracycline-stained teeth is very challenging. Tooth whitening may be a valid alternative to more aggressive treatments; however, patients should be aware of the limitations of tooth whitening therapy. Clinicians may select ...
