Investigating Waterlogging: Optical Micromorphological Examination of Surface Moisture on Acid-Conditioned Resin-Dentin

Summary: Waterlogging is a phenomenon in which the acid-etched dentin surface loses its moisture content when it is exposed to excess water. This study was conducted to examine the micromorphology of acid-etched dentin surfaces under water-logging conditions. Dentin samples were etched with 37% phosphoric acid for 15 seconds and then rinsed with water for 15 seconds. The samples were then either air dried or rehydrated by immersion in water for 15 seconds. The surfaces of the samples were examined using scanning electron microscopy (SEM). The results showed that the acid-etched dentin surface under water-logged conditions had a smoother and more uniform morphology than the acid-etched air-dried dentin surface. In addition, acid-etched dentin surfaces under waterlogged conditions had fewer open dentinal tubules than air-dried acid-etched dentin surfaces. These results suggest that waterlogging may result in a more uniform and dense acid-etched dentin surface, which may improve adhesion between resin and dentin.

Introduction: Waterlogging is a phenomenon in which the acid-etched dentin surface loses its moisture content when it is exposed to excess water. This can occur when acid-etched dentin is rinsed with water for too long or when acid-etched dentin is immersed in water before applying the adhesive. Over-watering can lead to decreased adhesion between resin and dentin.The exact mechanism by which waterlogging leads to decreased adhesion between resin and dentin is unknown. However, it is believed that overwatering may result in the formation of a layer of water on the surface of acid-etched dentin, which may prevent the adhesive from penetrating the dentin. In addition, overwatering can lead to the collapse of collagen fibers in dentin, which can also reduce adhesion between resin and dentin. Several studies have examined the effect of waterlogging on resin-dentin adhesion. These studies showed that waterlogging can lead to a significant reduction in adhesion between resin and dentin. However, the mechanism by which waterlogging leads to decreased adhesion between resin and dentin is still not fully understood.The purpose of this study was to study the micromorphology of acid-etched dentin surfaces under water-logging conditions. The hypothesis of the study was that waterlogging would result in a smoother, more uniform acid-etched dentin surface with fewer exposed dentinal tubules.Materials and methods

Dentin samples: Dentin samples were obtained from recently extracted human wisdom teeth. The teeth were cleared of soft tissue and cut into 2 mm thick plates. The plates were then embedded in acrylic resin and polished to a flat surface.

Acid etching: Dentin samples were etched with 37% phosphoric acid for 15 seconds. The samples were then rinsed with water for 15 seconds. OvermoisteningSamples were either air dried or rehydrated by immersion in water for 15 seconds. Scanning electron microscopy (SEM) The surfaces of the samples were examined using scanning electron microscopy(SEM).

Results: The results showed that the acid-etched dentin surface under water-logged conditions had a smoother and more uniform morphology than the acid-etched air-dried dentin surface. In addition, acid-etched dentin surfaces under waterlogged conditions had fewer open dentinal tubules than acid-etched dentin surfaces air-dried.

Discussion: The results of this study suggest that waterlogging may result in a more uniform and dense acid-etched dentin surface. This may be due to the fact that waterlogging results in the formation of a layer of water on the surface of acid-etched dentin, which can prevent the collapse of collagen fibers in dentin. More uniform and dense dentin surface.
