Seven new type metallocavitand complexes 1–7 were synthesized via the self-assembly of aluminum and magnesium atrane-likes. The recognition of R-2-butanol from racemic 2-butanol can be achieved in the chiral cavity of metallocavitand complex 5. The crystal structure of complex 5 showed that the

To compare and evaluate morphological changes and bacterial deposits in primary carious molars after caries excavation with Carie-Care, erbium-doped yttrium aluminum garnet (Er:YAG) laser, and round tungsten carbide bur.
UNASSIGNED
Thirty human carious primary molars extracted for
In the present study, 2,087 fifth-graders (mean age: 12 years) from two cohorts entered a 3-year clinical toothpaste trial. The study subjects were randomly allocated to two groups: one group was a positive control using a 0.83% NaFPO3 toothpaste, while the other group brushed with a test toothpaste
OBJECTIVE
The aim of this study was to investigate dental pulp reactions after a neodynium:yttrium aluminum perovskite laser pulse on the dentinal floor of occlusal cavities in an in vitro model.
METHODS
A Lokki dt laser was used at 30 Hz, 5 W, and 160 mJ for 0.5 s. The pulp reactions were analyzed
OBJECTIVE
Topically applied aluminum (AI) reduced fissure caries in rats with indigenous microflora, but neither therapeutic activity nor concentration effects have been studied in animals infected with caries-inducing bacteria. This study investigated the effects of solutions containing various AI
OBJECTIVE
To assess the effect of the erbium:yttrium aluminum garnet (Er:YAG) laser on bond strength of a total-etch adhesive system to the caries-affected dentin on the gingival wall.
METHODS
Ten human molars with proximal carious lesions were randomly divided into two groups. In the first group,
To expand and substantiate earlier experimental studies of fluoride compounds (SnF2, NaF, Na2PO3F and amine fluoride) with animals, the effect of the compound aluminum-fluoride hydroxide AlFx(OH)y . zH2O and aluminum lactate A1 [CH3 . CH(OH) COO]3 individually, combined, and in various tooth paste
Selective production of exotic species (SPES) is an ISOL-based accelerator facility that will be built in the Legnaro INFN Laboratory (Italy), intended to provide an intense neutron-rich radioactive ion beams obtained by proton induced fission of an uranium carbide target. Beside this main target, a
SPES (Selective Production of Exotic Species) is an Isotope Separation On-Line (ISOL) based accelerator facility that will be built in the Legnaro-Istituto Nazionale di Fisica Nucleare (INFN) Laboratory (Italy), intended to provide intense neutron-rich radioactive ion beams obtained by
BACKGROUND
Incipient carious lesions are characterized by subsurface dissolution due to more fluoride ions in the 50-100 microns of the tooth's outer surface.
OBJECTIVE
To determine an optimal power setting for 810 nm aluminum gallium arsenide laser for caries inhibition.
METHODS
Fifty-four
The design of a porthole die is one of the key technologies for producing aluminum profiles. For an aluminum profile with high length⁻width ratio and small cavity, it is difficult to control the metal flow through porthole die with the same velocity to ensure the die's strength. In the present
The effects of topically applied mouthrinses containing AlCl3, or AlK(SO4)2 on dental caries and plaque were investigated in a rat model. For comparison, NaF and a two-step treatment of AlCl3 and NaF were also tested. Six groups of 20 weanling rats were inoculated with Streptococcus sobrinus 6715
BACKGROUND
In recent years, significant developments have been taking place in caries removal and cavity preparation using laser in dentistry. As laser use is considered for cavity preparation, it is necessary to determine the quality of restoration margins. Glass ionomer cements have great
From the currently available choices, esthetic restorative materials for posterior teeth are limited to composite and ceramic restoration. Ceramic inlays/onlays are reliable solutions for both of these treatments. For successful treatment planning, usable ceramic and adhesive systems should be
This in vitro study assessed the marginal microleakage on class V cavities prepared with aluminum oxide air abrasion and restored with different glass ionomer cements. The cavities were prepared on the buccal and lingual surfaces of 15 sound third molars with an air- abrasion device (Kreativ Mach
