“…Reports of tannic acid use in dentistry as a desensitizing agent, astringent, and surface treatment for smear layer removal have been previously described (Bitter, 1989;Prati et al, 1992;Sabbak and Hassanin, 1998;Natsir et al, 1999;Okamoto et al, 1991;Tomiyama et al, 2004), but no information exists regarding its effect on the mechanical properties of dentin and adhesive-dentin interfaces. The present study showed that tannic acid significantly affected dentin matrix properties and resin-dentin bond strength; therefore, the null hypotheses must be rejected.…”

Dentin collagen is a major component of the hybrid layer, and its stability may have a great impact on the properties of adhesive interfaces. We tested the hypothesis that the use of tannic acid (TA), a collagen cross-linking agent, may affect the mechanical properties and stability of the dentin matrix. The present study evaluated the effects of different concentrations of TA on the modulus of elasticity and enzymatic degradation of dentin matrix. Hence, the effect of TA pre-treatment on resin-dentin bond strength was assessed with the use of two bonding systems. Sound human molars were used and prepared according to each experimental design. The use of TA affected the properties of demineralized dentin by increasing its stiffness. TA treatment inhi bited the effect of collagenase digestion on dentin matrix, particularly for 10%TA and 20%TA. The TA-dentin matrix complex resulted in improved bond strength for both adhesive systems.

“…Only the former method was employed in this study. Several previous studies have used dentin discs for the SEM testing [24][25][26][27]. Many hypersensitivity studies [25,[28][29][30] relied on subjective evaluation of the images, where the examiners compared the resultant images before and after treatment and ranked the treatments in terms of the Bbest to worst^coverage of the tubules.…”

“…APF treatment of dentin has been well studied; Vale et al have reported that the acid resistance of dentin was improved by APF treatment 17) , and Saunders et al have elucidated that root dentin was effectively protected by 1.23% APF gels 18) . In addition, studies have suggested that APF treatment might have an inhibiting effect on hypersensitive dentin 19,20) . However, dentin is less resistant to acid than enamel, and therefore when treated with the same level of acidity, carries a risk of dissolving and thus weakening the dentin.…”

Acidulated phosphate-fluoride (APF) is widely used for the prevention of enamel caries. The topical application of fluoride is a promising treatment for improving the acid-resistance of tooth, promoting its remineralization, and improving its crystallinity. APF contains a high concentration of fluorine ions (9,000 ppm); it first decalcifies the apatite in dentin, generating calcium and phosphate ions, which bind to fluoride ions, thus precipitating calcium fluoride. APF is prepared as an acidic solution (pH 3.5) and is used to reinforce the enamel. However, dentin is less resistant to acid than enamel. As such, APF treatment at the same acidity carries a risk of weakening the dentin after application. In many cases, wedge-shaped defect (WSD), root caries, and attrition can cause dentin exposure, to which the APF can attach. Therefore, in this study, we analyzed the effect of APF treatment on dentin by measuring Vickers hardness, making observations with scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM), and measuring average surface roughness (Ra). The findings of this study suggested that an acidulated phosphate fluoride (APF) treatment of 3 min or longer caused marked dissolution of dentin and posed the risk of deterioration of its initial strength. Therefore, careful management is required to preclude dentin dissolution when performing APF treatment for preventing dental caries. Knutson et al. 7) later proposed applying sodium fluoride solution. In the 1950s, Howell et al. 8) proposed the use of stannous fluoride solutions, and in the 1960s, Brudevold et al. 9,10) proposed the use of acid phosphate-fluoride (APF) solutions. These topical fluoride application methods are still commonly used today. These methods have many benefits, including formation of fluoroapatite, improvement of the crystallinity of the enamel, promotion of remineralization, and antimicrobial activity 11-14) , and are thus considered an effective means of preventing dental caries. APF is prepared as an acidic solution (pH 3.5) with a high concentration of fluorine ions (9,000 ppm). Once applied to a tooth, it initially decalcifies the surface. Calcium ions and phosphate ions are then generated; calcium ions bind to fluoride ions, and this leads to the precipitation of calcium
