Abstract

No data are available on the direct acute vascular effect of dental bond materials in the dental pulp. The purpose of the present study was to investigate the effect of composite resin bonding systems on the pulpal vascular diameter. Three groups of male Sprague-Dawley rats (weighing 300-490 g), each of 10 animals were used for this investigation. The left lower incisor of the rats was prepared for vitalmicroscopy. Changes in vessel diameter were recorded prior to; and 5, 15, 30, 60 minutes after the application of saline (control) or the bonding agents (test1: acetone containing--/Prime/Bond2.1, DeTrey/; test2: acetone free /Scotchbond Multi-Purpose Adhesive System, 3M/ bond material) on pulpal dentin as recommended by the manufacturer. In control rats, the vessel diameter was stable during the experiment. However, in the presence of bonding materials an enhancement was registered in vascular diameter (p <0.05). The bond materials applied directly onto a very thin layer of dentin show acute vasodilating effect on the rat pulpal microvessels, but no stasis or prestasis has been detected, indicating a possible reversible effect. We could not show any statistical difference between the vasodilatation caused by the acetone containing and the acetone free bonding material.
