“…Tap water was used by LeFevre and Manly (45), Rautiola and Craig (39), distilled water by Mahoney et al (46), Addy and Mostafa (47), Aquilino et al (48), de‐ionized water by Poolthong (37) and distilled water with thymol by White et al (49). Saline with some modifications was used by a number of researchers; this included aqueous sodium chloride (48), and saline solutions including Krebs–Ringer phosphate buffer (50, 51), phosphate‐buffered saline (42, 49, 52), phosphate‐buffered saline with sodium azide (51, 53) or thymol (54, 55), physiologic saline (43, 56, 59), formal‐saline (43), isotonic saline with sodium azide (57–60) and HEPES (N‐2‐hydroxyethylpiperazine‐N′‐2‐ethanesulfonic acid) saline (61). Other investigators have tested specimens after storing in formalin (49, 56), ethanol (49, 56), and saliva (62).…”

The application of light and heavy forces did not show any statistically significant differences in hardness and elastic modulus when compared with untreated teeth. The inconsistent increase or decrease of Ca, P and F contents between control and experimental teeth at sites of compression and tension were difficult to explain. There was more resorption by volume in the heavy force group as compared with the light group and controls. Our data also suggested that the high-pressure zones might be more susceptible to resorption after 28 days of force application.

This study quantified in vitro the root dentin moisture when 10% formalin (Group A), 3% sodium azide (Group B), and distilled water (Group C) were used as teeth storage media. The root dentin moisture of 66 extracted human mandibular single-rooted teeth was measured at baseline (day 0) and at 1, 3, 7, and 14 days using a digital grain moisture meter. The baseline dentin moisture value was used as a covariate in the generalized estimating equation (GEE) analysis. The mean dentin moisture values (%) ± standard deviation on days 0, 1, 3, 7, and 14 were 10.6±0.64, 14.3±0.71, 14.6±0.84, 14.4±0.64, and 14.7±0.75 (Group A); 11.4±0.94, 14.6±0.95, 14.6±0.76, 14.6±0.93, and 14.8±0.81 (Group B); and 10.2±0.95, 12.8±0.90, 13.3±0.95, 13.0±0.91, and 13.2±0.89 (Group C), respectively. The dentin moisture increased in all three groups; however, there was no overall significant difference in moisture between the formalin and sodium azide groups.

“…15 There are other examples of dental products that seal dentin very well but have low bond strengths. 19 EIS may be useful in following slow water sorption of nonionic dental resin-dentin bonds over many months. Theoretically, if any debonding begins to develop, the microscopic gap should be filled with water, which should create a double-layer capacitance and a second time constant that increases the capacitance of the bonded assembly even before a critical size defect develops.…”

Electrochemical impedance spectroscopy (EIS) offers a potentially nondestructive quantitative method for measuring the stability of resin films and or resin-bonded dentin over time. The purpose of this study was to measure the electrical impedance of five experimental dental adhesives of increasing hydrophicities as 30-microm films and as resin-bonded coatings on acid-etched dentin. Resin films or resin-coated dentin disks were placed in U-shaped chambers containing pairs of Ag-AgCl electrodes in 0.1M KCl. Electrical impedance spectra were run at day 0, 1, 7, 14, and 21 days. All resin films and resin-bonded dentin showed increases in capacitance during the first day of storage in electrolyte. This was usually associated with an increase in the pore resistance of the resins. Generally, resin-bonded dentin gave lower impedance values than their respective resins (resins 1-4) but solvated resin 5 bonded to water-saturated dentin gave higher capacitance and impedance values than resin 5 films. However, solvated resin 5 films gave higher impedance values than resin 5-bonded dentin. This behavior was confirmed by TEM examinations of silver uptake into films of neat resin 5 vs. ethanol-solvated resin 5, where water tree-like structures seen in the former were not seen in the latter. EIS is useful in examining changes in the capacitance and electrical impedance of very hydrophilic, ionic methacrylate resins. Its utility in detecting degradation in resin-bonded dentin interfaces remains to be determined in longer term studies.
