Dental hard tissue conditions can be of pre- or post-eruptive nature, such as enamel fluorosis and erosive tooth wear (ETW), respectively. Dental enamel fluorosis is caused by the chronic and excessiv...
Very little data are known about charcoal toothpastes. The aim of this study was to counteract the missing data by determining the relative dentin abrasivity (RDA) and relative enamel abrasivity (REA)...
Radioactively charged dentin and enamel samples were randomly divided into groups of eight specimens. Each group was brushed with two of total 12 charcoal toothpaste slurries and with a standard abras...
The RDA and REA values of the charcoal toothpastes have a broad range of 24-166 and 0-14, respectively....
The RDA and REA values do not differ significantly from previously tested commercially available toothpastes. However, the lack of fluoride compounds in many of the investigated charcoal toothpastes c...
Tooth wear is a commonly reported finding globally; however, many patients are unaware of having tooth wear. Identifying early signs of erosion, abrasion or attrition and determining the risk factors ...
This study compared the surface change on natural and polished enamel exposed to a joint mechanical and chemical wear regimen....
Human enamel samples were randomly assigned to natural (n = 30) or polished (n = 30) groups, subjected to erosion (n = 10, 0.3% citric acid, 5 min), abrasion (n = 10, 30 s), or a combination (n = 10)....
After four cycles, polished samples had mean step heights of 3.08 (0.40) μm after erosion and 4.08 (0.37) μm after erosion/abrasion. For natural samples, these measurements were 1.52 (0.22) μm and 3.6...
Natural enamel, when exposed to erosion alone, showed less wear and minimal subsurface alterations. But with added abrasion, natural enamel surfaces saw increased wear and notable subsurface changes c...
The pronounced subsurface lesions observed on eroded/abraded natural enamel surfaces highlight how combined wear challenges may accelerate tooth tissue loss....
Sodium hexametaphosphate (HMP) as toothpaste additive is claimed to reduce erosive tooth wear and to stabilize stannous ions. However, little is known about the impact of concentration and its interac...
This systematic review evaluated the efficacy of monovalent and polyvalent fluoride group compared to the non-fluoride group on the prevention of enamel erosion associated or not with abrasion in in s...
This review was registered in the PROSPERO (CRD42017071118) and followed PRISMA 2020 guidelines. A systematic and comprehensive search was performed using PUBMED, WEB OF SCIENCE, SCOPUS, EMBASE, BBO, ...
730 studies were obtained and after exclusion of duplicates, 311 were included for title and abstract reading. Two independent authors (kappa= 0.98) systematically conducted the selection phase. Consi...
Network metanalysis showed that polyvalent fluoride group, especially Sn-compounded, prevented enamel wear by erosion and erosion/abrasion compared to the non-fluoride group and monovalent fluoride gr...
This study was undertaken to estimate the prevalence and severity of tooth wear (TW), as well as to assess non-biological and biological risk indicators for TW outcomes in adults. A cross-sectional st...
The aim of this study was to analyze the anatomic crowns of the maxillary and mandibular dentition concerning the mesiodistal, buccolingual measurements which will be used to establish normative data ...
A newly developed instrument termed as CAITN probe was used to measure CA of the tooth more quantitatively. The mesiodistal and buccolingual width of all the 14 maxillary and mandibular teeth from the...
Descriptive statistics were calculated for each group independently. The statistical significance of the difference in mean in mesiodistal and buccolingual diameters between males and females was calc...
The present study was conducted as an initial step in the process of development of the novel tool or index enabling the dentists to organize the health-care needs of their patients by facilitating st...
To evaluate the influence of air-abrasion of enamel with three different desensitizing powders on the whitening effect of a bleaching gel containing 40% H...
Forty human incisors, extracted and prepared, were acquired for this study and subsequently randomized into four groups (n = 10). The control group specimens underwent no pretreatment prior to the ble...
Tooth color change outcomes revealed that there were no statistically significant results with respect to the interaction of the two criteria (treatments and time) (p = 0.990). Additionally, there wer...
The use of the tested desensitizing powders prior the bleaching procedure did not affect the tooth color change induced by the tested bleaching agent....
Tooth color change and whiteness are not affected by air-abrasion desensitizing treatments when applied prior to in-office bleaching procedures....
The aim of this research was to evaluate the abrasive dentin wear that can be induced by three commercial whitening toothpastes following a tooth-brushing simulation (TBS) corresponding to a three-mon...
