BACKGROUND Contamination of dentin with hemostatic agents might exert a deleterious effect on adhesive procedures on dentin. The present study was undertaken to investigate the effect of aluminum chloride hemostatic agent on marginal gaps in Cl V giomer restorations. MATERIAL AND METHODS Fifty sound bovine permanent incisors were selected for the purpose of this in vitro study and Cl V caviti...

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:...

OBJECTIVES/HYPOTHESIS To determine the ototoxic potential of aluminum acetate (0.5%)/benzethonium chloride (0.03%) otic solution in the chinchilla animal model. STUDY DESIGN A randomized, prospective, controlled study was conducted in the chinchilla animal model. METHODS Fourteen female chinchillas were used. After an incision was made in each tympanic membrane, baseline auditory brainstem ...

The asymmetric unit of the title salt, C(7)H(9)N(2)O(2) (+)·Cl(-), contains two independent cations and anions. In the crystal, each N-methyl-4-nitro-anilinium cation is linked to two Cl(-) anions via N-H⋯Cl hydrogen bonds. π-π stacking is observed between the benzene rings of adjacent cations [centroid-to-centroid distances = 3.7684 (14) and 3.7917 (7) Å].

   The aim of the present study was to synthesis a series of phthalimides based on our previous works and examine their anxiolytic properties. Using a three steps process, phthalimides were prepared from the corresponding di-methyl phthalate derivatives. Phthalic anhydride was nitrated to produce 3-nitrophthalic acid. Ring closer of either 3-nitrophthalic acid or di-methyl phthalate with urea w...

Background: Coagulation is a treatment procedure for metalworking fluids (MWFs). This study aimed to optimize coagulation using four coagulants and compare the results. Methods: In this research, the outputs of a coagulation procedure in chemical oxygen demand (COD) removal, turbidity, and the release of oil were investigated using four coagulants, ferric chloride (FeCl3), ferric sulfate (Fe2(...

The aymmetric unit of the title compound, C(8)H(18)N(+)·Cl(-), consists of one crystallographically independent 1-methyl-1-propyl-pyrrolidinium cation and one chloride anion, both of which lie in general positions. Minor hydrogen-bonded C-H⋯Cl inter-actions occur. However, no classical hydrogen bonding is observed.
