We used a special-purpose glass microfiber sample, Johns-Manville Code 100/475, to study the effects of various acid and alkali treatments on biological activity as assessed by inflammation in the mouse peritoneal cavity, the leaching of Si, and the phase contrast optical microscopy (PCOM) fiber
Oxalic acid and its metal oxalate salts have been used extensively in dentistry in a range of applications: as desensitisers, in cavity preparation, and as bonding agents. This study investigated the influence of oxalic acid upon the working time, initial setting time, 24-h hardness and compressive
BACKGROUND
Non-carious cervical lesions are usually associated with dentin hypersensitivity. The use of oxalic acid in restorations of these lesions could be beneficial in relieving pain.
OBJECTIVE
To evaluate the use of oxalic acid in restorations of non-carious cervical lesions.
METHODS
A
OBJECTIVE
To evaluate the use of oxalic acid in restorations of noncarious cervical lesions.
METHODS
Twenty volunteers of both sexes between 24 and 55 years old, with at least two lesions that were restored with the techniques to be evaluated, were selected. Ninety teeth were randomly divided into
An oxalic acid solution has been proposed as a conditioning agent for resin composite restorations in two commercial adhesive systems. The durability of 163 class III restorations, including 12 class IV restorations, in cavities pre-treated with an oxalic acid total etch technique or an enamel etch
BACKGROUND
New acids such as oxalic acid have been introduced as a conditioning agent in the total-etch technique. There is concern about long-term retention of the acid on enamel in relation to the superficial etch effect.
OBJECTIVE
This in vivo study evaluated the marginal adaptation to enamel
The present study investigated the compounds present in the low molecular mass fraction of Lentinus edodes mushroom (shiitake) extract and their anti-virulence activity against oral pathogens (reference and clinical Streptococcus mutans, Actinomyces naeslundii, and Prevotella intermedia strains).
Metabolic products of Aspergillus species may play a significant role in the pulmonary destructive process. We describe a patient who died of respiratory failure, in whom postmortem examination revealed aspergilloma and numerous calcium oxalate crystals around the aspergilloma, as well as extensive
The keeper and cast dowel-coping, as a primary component for a magnetic attachment, is easily subjected to corrosion in a wet environment, such as the oral cavity, which contains electrolyte-rich saliva, complex microflora and chewing behaviour and so on. The objective of this in vitro study was to
Nine noncarious human molars were extracted and stored in saline solution. Three standard occlusal cavities with beveled enamel margins were prepared on each tooth and etched with the etching solutions of three dentinal adhesive systems: (1) 37% phosphoric acid solution, (2) 4.3% oxalic acid and
Several new bonding systems have been reported that promote strong adhesion. This in vivo study involves treatment with two experimental bonding systems of Class V cavity preparations in the teeth of three Macaca fascicularis primates and reports the pulpal responses and degree of micro-organism
Several microbes were isolated from the contaminated fuel-oil in Taiwan and the microbial corrosion of aluminum alloy A356-T6 was tested by MIL-STD-810E test method. Penicillium sp. AM-F5 and Cladosporium resinac ATCC 22712 had significant adsorption and pitting on the surface of aluminum alloy,
OBJECTIVE
To investigate bone-to-implant bonding for some novel surface modifications with a hierarchic structure and to correlate the in vivo results with surface roughness parameters.
METHODS
Newly developed implants surfaces were tested in rabbits and compared with the commercially available
Graphene-carbon nanotube nanocomposites that contain multitubular co-axial and hollow cavity microstructures are prepared. Nanometer-scale graphene sheets are anchored with oxalic acid and consequently linked to each other via oxalyl bonding, thereby self-assembling into numerous outer tubes with
The host-guest interaction between four hexaaza macrocyclic ligands (3,6,9,17,20,23-hexaazatricyclo[23.3.1.1]triaconta-1(29),11,13,15 (30),25(27)-hexaene (Bd), 3,6,9,16,19,22-hexaazatricyclo[22.2.2.2]triaconta-1(27),11(30),12,14(29),24(28),25-hexaene (P2),
