“…19,20 Van der Graaf and ten Bosch 19 reported that mineralized dentin shrank 1.7% to 2.0% in the plane perpendicular to the tubules and 1.4% to 1.7% in the directions of the tubules (the direction measured in the current study). Although we used adjacent normal dentin as intraspecimen controls, that dentin may have been altered by the carious process.…”

Caries-affected dentin contains less mineral and more water than surrounding normal dentin. Such dentin should be less stiff and should shrink more than normal dentin when dried. The purpose of this study was to test the relationships between the stiffness, shrinkage, and water content of caries-affected versus normal dentin. Extracted human carious third molars were stained with caries-detector dye and the occlusal surfaces ground down until only caries-affected dentin remained, surrounded by normal dentin. Dentin disks were prepared from these crowns placed in a aluminum well positioned under a modified thermal mechanical analyzer. Changes in specimen height and stiffness were measured following drying or static loading in both caries-affected and surrounding normal dentin. Core samples of these two types of dentin were used to gravimetrically measure water content. Two-way ANOVA and regression analysis was used to test the relationship between shrinkage versus water content, stiffness versus water content, and stiffness versus shrinkage. Cariesaffected dentin was found to be less stiff and contained more water than normal dentin (p < 0.05). Regression analysis revealed highly significant inverse relationships between stiffness and water content, and stiffness and shrinkage (p < 0.0005).

“…1). During rehydration, air-dried human dentin regains its original dimensions when wet again due to water uptake 14,15) . Therefore, it appeared that water sorption by dry dentin caused an expansion of the dentin substrate, and then further caused debonding between the tooth and the resin composite.…”

Effect of Water on Bonding of One-bottle Self-etching Adhesives

et al. 2008

This study evaluated the effect of water on dentin substrate bonding of one-bottle self-etching adhesives. Dentin substrates were divided into two groups: wet and dry dentin. Wet dentin is the normal substrate for bond testing whereas dry dentin was dehydrated in a desiccator for 24 hours. Bonded dehydrated teeth were then divided into two subgroups: stored in water or in desiccator for 24 hours. Microtensile bond strength of resin to dentin was measured using three one-bottle self-etching adhesives. In addition, nanoleakage evaluation was performed through the analyses of SEM and TEM micrographs. The bond strength of dry-dentin group was significantly greater than that of wet-dentin. Further, the amount of nanoleakage within the adhesive interface of dry-dentin group was less than that of wet-dentin. Results showed that bond strength and nanoleakage formation depended on the bonding substrate (wet versus dry dentin) before bonding. One-bottle self-etching adhesives might suck the water from dentinal tubules during bonding by osmosis, leading to nanoleakage formation and thus a decline in bond strength.

“…In this case, water is actively pulled from the underlying hydrated dentine to the adhesive by osmotically induced forces, due to the high osmolality of the primers or adhesives employed [13][14][15][16]. It is not surprising, therefore, to find silver-stained pathways of water within the adhesive originating from the tubule orifice towards the adhesive.…”
