“…However, it is desirable to deposit artificial stain only on the surface of the enamel without discoloring the interior of the tooth substrate when evaluating the removal of extrinsic staining. In this study, we employed 10% citric acid / 3% ferric chloride aqueous solution (10-3 solution, as used in the pretreatment for dentin bonding of 4-META/MMA-TBB resin) ( 13 ) and tannic acid aqueous solution to generate extrinsic artificial stain for the enamel surface. Fe ions (III) combine with tannic acid to produce brown or black ferric tannate when exposed to air ( 14 ).…”

Background This study aimed to investigate the combined effect of baking soda and electric toothbrushing on the removal of artificial extrinsic stain in vitro . Material and Methods Flat enamel surfaces of 15 bovine incisors were artificially stained with 10% citric acid / 3% ferric chloride solution followed by 1% tannic acid solution. These specimens were randomly divided into three groups (n = 5) – Group S+B: brushing with an electric toothbrush and baking soda, Group S+C: brushing with an electric toothbrush and fluoride dentifrice, Group S: brushing only with an electric toothbrush. Color values (L*, a*, and b*) and surface roughness were measured before and after brushing (after 1, 2, 3, and 5 min). The data were statistically analyzed using two-way analysis of variance and Tukey’s honest significant difference test as a post hoc test ( p < 0.05). Results The L* value of Group S+B increased over time, and was significantly different between before brushing and at 5 min ( p < 0.05). A significant difference in the ΔE* value of Group S+B was found at 5 min ( p < 0.05). However, no significant difference was found in the ΔE* values of Group S+C and Group S. No significant differences in Ra were found in any of the groups. Conclusions The results of this study suggest that the combined use of baking soda and electric toothbrushing has an excellent stain-removing effect compared with electric toothbrushing with a fluoride dentifrice. Additionally, the changes in surface roughness were similar to the changes caused by the use of general dentifrices. Key words: Baking soda, dentifrice, extrinsic stain removal, color change, surface roughness.

“…However, Kameyama et al 23) reported that citric acid conditioner which contained ferric chloride was less effective for heated dentin to recover the bond strength than HEMA application. Imai et al24) insisted that ferric ions adsorbed onto dentin collagen may promote MMA polymerization initiated by TBB, thus influencing the bond strength of 4-META/MMA-TBB resin to dentin.…”

This study was conducted to examine the shear bond strengths of orthodontic brackets to ground enamel with two selfetching adhesives (Beauty Ortho Bond and Transbond XT) and two phosphoric acid-etching adhesives (Kurasper F and Orthomite Superbond). After the bonded specimens were stored in water at 37℃ for 24 hours, they were subjected to thermal cycling (TC) at 0 and 5000 cycles. Then, shear bond test was performed at a crosshead speed of 1 mm/min. Results indicated that the self-etching adhesives did not significantly differ in bond strength before and after TC (p>0.05), while the phosphoric acid-etching adhesives showed a significant reduction after TC (p<0.05). The predominant modes of bracket failure for the self-etching adhesives were at the enamel-resin interface, leaving less than 50％ of the adhesive on the enamel surface. It was concluded that the self-etching adhesives exhibited stable bond strength to ground enamel without causing decalcification nor damage to the enamel surface.
