Within six months of opening of the new Dublin Dental Hospital in September 1998, areas of corrosion were observed on many of the baseplates of the hospital's 103 dental chair units (DCUs) at the site of attachment of the suction hoses. The corroded areas were heavily contaminated with Pseudomonas spp.

Two new local exhaust systems, intended primarily to control patient mouth emissions of N2O, were installed in a dental operatory, and resulting exposure concentrations to dental personnel were observed. The exposures were found to be typically unaffected by the presence and operation of these new controls.

Detecting margin leakage of dental composite restorations
Journal of Biomedical Materials Research, 1983AbstractThe degree of microleakage between a restoration and the cavity wall is difficult to quantify objectively. A silver‐staining method is used and compared to the radioisotope method with results that indicate a superior definition and more accurate evaluation of microleakage.

Marginal leakage of dental restorations subjected to thermal stress
The Journal of Prosthetic Dentistry, 1969Abstract The effects of thermal stress on the microleakage of dental restorations of varying ages were measured with radioisotope. Microleakage around one-week amalgam restorations was increased when the restorations were subjected to 500 temperature cycles.

Experimental Marginal Leakage Around Dental Amalgams Placed in Artificial Cavities
Journal of Dental Research, 1984Experimental marginal leakage of high- and low-Cu amalgam restorations placed in acrylic teeth, where the cavities were untreated or painted with denatured collagen and/or a CaP slurry, was assessed after specimens were stored in a 1% NaCl solution for ten days and for one yr. All specimens stored for ten days showed severe marginal leakage.

Background: Bisphenol A (BPA) derivatives monomers as resins are common components in dental restorative materials and materials used for orthodontic treatment. However, they are a source for BP-A leakage, which can affect adult and child health as an endocrine disruptor.
