“…Varnish is easy to apply, safe and well tolerated by babies; young children and individuals who require assistance for disabilities, besides, the formation of a mechanical barrier, in comparison with other fluoride vehicles (17). In the present study, the varnishes had the same fluoride concentration, were applied only once and completely removed after 6h (11,12,17,18) in order to simulate the clinical situation, which the varnishes might be removed through tooth brushing and chewing, focusing on the chemical effect rather than on the mechanical protection. This is the first study to assess the effect of varnishes containing fluoride with or without calcium or xylitol to reduce enamel erosion and progression of erosion.…”

Evaluated the effect of CPP-ACP/NaF and xylitol/NaF varnishes in reduce erosion and progression of erosion. Forty enamel blocks were divided into four groups (n=10): G1=CPP-ACP/NaF varnish (MI varnishTM); G2=xylitol/NaF varnish (Profluorid®); G3=NaF varnish (Duraphat®, positive control) and G4=deionized water (MilliQ®, negative control). Samples were immersed in Sprite ZeroTM (pH 2.58, 4x/day, 3 days), in between immersions, the specimens stayed in artificial saliva. After 3 days of erosion, the eroded area was divided in two (half of one received an additional varnish layer while the other half repeated the same 3-day erosion cycle). The 3D, non-contact profilometry technique was used to determinate tooth structure loss (TSL) and surface roughness (SR). Scanning electron microscopy (SEM) and 3D images were utilized to evaluate the topography of the samples. Mann-Whitney, one-way ANOVA and Tukey tests were used (significance level of 0.05%). SEM and 3D images were descriptively evaluated. After 3 or 6 days of erosion, all tested varnishes were better than G4 (p<0.05) for TSL and SR. In addition, G1 had lower values for TSL than G3 (p<0.05) after 3 days of erosion. Under SEM and 3D images observation, all groups presented porosity, irregularities and depressions on the surface enamel after 3 and 6 days of erosion, more pronounced in G4. An application of topical NaF varnishes was effective in reducing TSL and enamel roughness after erosion challenges, being the CCP-ACP/NaF varnish more effective than NaF varnish and water after 3 days of erosion.

“…The usage of topical fluoride varnishes and chewing gums to increase salivary flow may have some beneficial effects in reducing the dental erosion. Topical fluoride varnishes form a protective layer on the surface of the tooth thus reducing the contact of acid with enamel and also helping in enamel demineralization (3,23).…”

A time based objective evaluation of the erosive effects of various beverages on enamel and cementum of deciduous and permanent teeth

2020

Background: Erosion of the teeth is a chronic irreversible process leading to loss of surface enamel and even the dentin, in turn causing sensitivity and pain. Increased consumption of carbonated beverages remains a major cause for dental erosion. However, many of the so called safe beverages that are consumed may also have sufficiently low pH to cause dental erosion. One of the parameters to measure the dental erosion is estimation of hardness and surface roughness. Thus, this study aims to evaluate the difference in hardness and surface roughness of enamel and cementum using three beverages namely (carbonated drink, lime soda, lime juice) in deciduous and permanent teeth. Material and Methods: Ten permanent and three deciduous teeth samples each were kept in lime juice, lime soda, carbonated beverage and tap water. The VHN using Vickers hardness tester and Ra value using surface profilometer were assessed at baseline, 1 day and 10 days. Results: At the end of 10 days the decrease in hardness of enamel of permanent teeth was maximum for teeth immersed in carbonated beverage followed by lime soda and lime juice. However, in the deciduous teeth it was observed that the VHN drop was maximum at 1 day in relation to teeth immersed in carbonated beverage followed by lime juice and lime soda. The hardness of cementum decreased significantly at the end of ten days both in deciduous as well as permanent teeth. Conclusions: The present study shows that many of the most commonly used beverages like lime juice and lime soda have a sufficiently low pH to cause erosion of the enamel surface as well as that of cementum of both deciduous and permanent teeth. Though protective mechanisms do exist in the oral cavity to neutralize the acids present in these beverages, continuous usage of these beverages leads to irreversible damage to the tooth structure.

“…The choice of 10 blocks per group was made after performing a sample calculation to detect a significant 50% difference in mean mineral loss in each treatment group as compared with the negative control group while considering a statistical power of 80%, a unilateral test, and a significance level of 5%. 14 The BioEstat 5.3 statistical analysis software program (Institute of Sustainable Development Mamirauá, Tefé, Amazonas, Brazil) was used to successfully detect a significant 50% difference in mean mineral loss in each treatment group in comparison with in the control group, considering a statistical power of 80%, a unilateral test, and a significance level of 5%. The blocks were exposed to an erosive challenge via immersion in a low-pH solution followed by immersion in another solution with neutral pH and a single application of the following products: (1) Ca 2 -MSN solution; (2) CPP-ACP slurry (CG America, Alsip, IL, USA); (3) CPP-ACP/F − slurry (CPP-ACP + 900-ppm concentration of F − from GC Corp., Tokyo, Japan); (4) TiF 4 solution (1%); or (5) sodium fluoride solution (NaF 1.36%); or (6) Milli-Q ® water (Millipore Corp., Burlington, MA, USA) as a negative control.…”

The use of a new calcium mesoporous silica nanoparticle versus calcium and/or fluoride products in reducing the progression of dental erosion Objective: There is increasingly common the consumption more times a day of foods and acidic drinks in the diet of the population. The present study aimed to evaluate and compare the effects of a calcium mesoporous silica nanoparticle single application of other calcium and/or fluoride products in reducing the progression of dental erosion. Methodology: Half of the eroded area was covered of 60 blocks of enamel, after which the block was submitted to the following treatments: (Ca 2+-MSN), casein phosphopeptideamorphous calcium phosphate (CPP-ACP); CPP-ACP/F-(900 ppm F−); titanium tetrafluoride (TiF 4 1%) (positive control); sodium fluoride (NaF 1.36%) (positive control); and Milli-Q ® water (negative control) before being submitted to a second erosive challenge. A surface analysis was performed via a three-dimensional (3D) noncontact optical profilometry to assess the volumetric roughness (Sa) and tooth structure loss (TSL) and and through scanning electron microscopy (MEV). An analysis of variance (ANOVA) and Tukey's test were performed. Results: Regarding Sa, all experimental groups exhibited less roughness than the control (p<0.05). The TSL analysis revealed that the Ca 2+-MSN and NaF groups were similar (p>0.05) and more effective in minimizing tooth loss compared with the other groups (p<0.05). Conclusions: The Ca 2+-MSN and NaF treatments were superior compared with the others and the negative control.
