“…9 It has been shown that enamel treated with AlCl 3 solution for 20 minutes could uptake aluminum (Al) from the solution, especially within the first 20 µm of enamel. 20 Moreover, this AlCl 3 treated enamel revealed inhibition of the demineralization process of hydroxyapatite (HAP), which was exposed to a demineralizing solution, [21][22] even though the Al concentration was as low as 0.1 µmol/l. 23 This mechanism has been explained by displacement of calcium in the HAP by Al, which results in the very insoluble Al (OH) 2 H 2 PO 4 compound.…”

A self-etching adhesive exhibited significantly lower bond strength to dentin contaminated with 25% aluminum chloride solution compared to normal dentin, but a total-etching adhesive exhibited no difference in bond strength to either contaminated or normal dentin. Longer primer application of the self-etching adhesive significantly increased the dentin bond strength of the contaminated group. SUMMARYThis study evaluated the bond strength of a totaletch and a self-etch adhesive to dentin contaminated with a hemostatic agent containing aluminum chloride (AlCl 3 ). Eighteen occlusal dentin discs were prepared from human molars. Each disc was ground and sectioned into two halves, one for normal dentin and the other for contaminated dentin. The specimens of both normal and contaminated dentin were randomly divided into three groups and treated with the following materials: 1) Excite (EX); 2) Clearfil SE Bond with 20-second primer application time (CB 20) and 3) Clearfil SE Bond with 40-second primer application time (CB 40). The microshear bond strength specimens were prepared using the resin composite Clearfil APX. The bond strengths were evaluated on a universal testing machine. Statistical analysis was performed at α=0.05. The surface micromorphology and aluminum content of the different dentin conditions were also examined. In EX, no significant difference was found between the bond strengths of normal dentin and contaminated dentin. The bond strength of CB20 to contaminated dentin was significantly lower than that to normal dentin. The

Aim: This study evaluated the effect of three different contamination removal methods on bond strength of one-step self-etching adhesive to dentin contaminated with an aluminum chloride hemostatic agent. Materials and methods:One hundred noncarious adult molars were used in this study; 2-mm-thick dentin disks were prepared and randomly assigned to 5 groups (n = 20). Group I: control; group II: hemostatic agent-contaminated; group III: hemostatic agent-contaminated and rinsing with water; group IV: hemostatic agent-contaminated and ethylene diamine tetraacetic acid (EDTA) application; and group V: hemostatic agent-contaminated and phosphoric acid application. Clearfil S3 Bond was used to bond composite to dentin surfaces. Subsequent to adding composite cylinders the shear bond strength test was performed. Data were analyzed by one-way ANOVA and Tukey test. Two additional specimens from each group were prepared and evaluated under scanning electron microscope (SEM).Results: There were statistically significant differences in bond strength among the groups (p < 0.001). In two-by-two comparisons statistically significant differences were observed in bond strength values between all the groups (p < 0.001) except for groups I and IV (p = 0.933). Conclusion:Aluminum chloride hemostatic agent adversely affected the bond strength of self-etch adhesive to dentin. However, application of EDTA increased the bond strength to the level of normal dentin.Clinical significance: EDTA and phosphoric acid removed aluminum chloride hemostatic agent contamination of dentin surfaces. However, unlike EDTA phosphoric acid failed to increase the bond strength of self-etch adhesive to dentin to the level of the control group.

“…Investigations into the cariostatic mechanism for Al have demonstrated that topical treatment with Al solutions in creased the resistance of enamel to acid dissolution [Adler and Csoban, 1948;Manly and Bibby, 1949;Putt and Kleber, 1985;Matsuo et al, 1987] and deposited Al in the surface enamel [Clarkson, 1976;Kleber and Putt. 1985].…”

“…Inves tigations with F indicate that repeated applications with low concentrations of F are more beneficial than single treat ments with high F concentrations [Poulsen and Larsen, 1975;Ericsson, 1977;Fejerskov et al, 1981;Wei, 1985;Bel tran and Burt, 1988]. Also, Kleber and Putt [1985] showed that 4 consecutive 5-min applications with a 'suboptimum ' Al concentration, similar to dietary exposure and accumu lation, resulted in more uptake of Al by enamel than a single 20-min exposure with a 7-fold greater Al concentration.…”

The effects of sequentially applied solutions containing aluminum (Al) on enamel uptake and inhibition of acid dissolution were investigated. Following 10 consecutive 5-min treatments with seven Al solutions varying in concentration from 0.15 to 2.0 mmol/l, the subsequent acid dissolution of enamel was progressively reduced from 0 to over 70%. Teeth treated with 1.5 mmol/l Al from 1 to 30 consecutive 5-min periods demonstrated a stepwise increase in the reduction of enamel acid dissolution ranging from about 10 to 90%. Following the same treatment regimen, the amount of Al deposited in the enamel varied from 2,500 ppm after a single 5-min application to approximately 9,000 ppm after 20 or 30 consecutive treatments. These experiments showed that teeth repeatedly exposed to low concentrations of Al solutions (i.e. < 2 mmol/l) progressively accumulated significant amounts of Al in the surface enamel, which was associated with a concomitant decrease in the acid dissolution rate of enamel.
