AIM To determine if the addition of inert fillers to a bioactive dental restorative composite material affects its degree of conversion (DC), polymerization shrinkage (PS), and microhardness (HV). METHODS Three amorphous calcium phosphate (ACP)-based composite resins: without added fillers (0-ACP), with 10% of barium-glass fillers (Ba-ACP), and with 10% of silica fillers (Si-ACP), as well as ...

We describe the design and evaluation of an agent that uses the fillers um and uh in its speech. We describe an empirical study of human-human dialogue, analyzing gaze behavior during the production of fillers and use this data to develop a model of agent-based gaze behavior. We find that speakers are significantly more likely to gaze away from their dialogue partner while uttering fillers, esp...

BACKGROUND A new family of next-generation non-animal hyaluronic acid (HA) dermal fillers was approved by the FDA in June 2006. Compared with other HA fillers available in the United States at the time of writing, these new fillers have a higher concentration of HA, higher concentration of cross-linked HA, and a smooth consistency--which should promote long-lasting corrections and a smooth, nat...

Japanese has various forms of fillers. However, the characteristics of each form have yet to be well understood. We use a large corpus of spontaneous Japanese speech and conversation and focus on three frequently observed types of fillers : e-, ma-, and demonstrative-type fillers. We show that it is possible to characterize Japanese fillers from the viewpoint of how a speaker concerns himself w...

BACKGROUND As microbial agents have been associated with late adverse effects related to fillers antibiotic treatment has been envisaged. OBJECTIVE To determine whether biomaterials favor bacterial growth and/or attract bacteria. METHODS Hyaluronic acid, semi-permanent fillers, such as calcium hydroxylapatite, and permanent fillers, such as polyalkylimide/polyacrylamide, were used. Experime...

Nanotubes have been shown to possess intriguing mass transport properties, and are being incorporated into polymeric membranes for molecular separations. Although models have been developed to predict the effective permeability and selectivity of composite membranes with non-spherical fillers, they only apply to fillers with isotropic transport properties. However, molecular transport in tubula...

Hyaluronic acid (HA) dermal fillers are the most widely used injectables to augment facial volume without surgery. HA dermal fillers are popular because of their ease of administration, predictable effectiveness, good safety profile, and quick patient recovery. The most common patient complaint is pain. Our goal is to review the current literature on HA fillers and compare outcomes with and wit...

Although it has long been observed that some children incorporate unglossable syllables into their early utterances, it has been difficult to integrate these 'fillers' into theories of language acquisition. Because they straddle boundaries between phonology and morphosyntax, and between pragmatics and lexicon, they do not fit neatly into linguists' notions about 'modules' of language. Fillers h...

Functional lignin-SiO₂ hybrid fillers were prepared for potential application in binders for phenolic resins, and their chemical structure was characterized. The properties of these fillers and of composites obtained from them with phenolic resin were compared with those of systems with lignin or silica alone. The chemical structure of the materials was investigated by Fourier transform infrare...

The author recommends that, contrary to currently accepted protocol, patients undergo skin testing before receiving injectable hyaluronic acid (HA) gel fillers. The risk of hypersensitivity to HA gel fillers, although low compared with bovine collagen, is a factor to consider. As larger volumes of fillers are injected, more extensive and vigorous reactions may be seen.
