The marginal leakage of some dental cements in humans: a PIXE-microbeam approach
AIP Conference Proceedings, 1999The marginal leakage and water absorption of dental cements and restorative materials has been investigated by many authors with several techniques, some of which led to valid results. However, no technique could give, by itself, information both on leakage and water absorption, as these measurements usually need different investigations.

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.

[Damage to the dental pulp by composite bonding systems: leakage or toxicity].
Nederlands tijdschrift voor tandheelkunde, 2002The fourth generation bonding systems demonstrate an excellent adhesion to the dental hard tissues. The marginal seal along the composite-resin restoration does, however, not totally prevent microleakage and, moreover, the bonding system may deteriorate with time.

The marginal leakage at the dentine/composite interface in Class II composite restorations subjected to thermal cycling has been effectively evaluated using the silver staining technique. The presence of a bonding agent at the dentine/composite interface is found to improve adhesion.

It was the purpose of this in vitro investigation to evaluate the effectiveness of several brands of sealed, reusable prophylaxis angles to keep internal materials within the internal portions of the head of the prophylaxis angle, and not allowing contaminates to leak out.

The use of silver amalgam as a tooth filler is under constant critical review because of its mercury content. After a review of the literature on this subject, in vitro spectrophotometry was used to assay the release of mercury by these amalgams in basal conditions.The experiment was conducted in two phases using standard doses of amalgam.

The purpose of this study was to evaluate whether manipulation or position change of the head during dental procedures for handicapped patients (mentally retarded) using a reinforced laryngeal mask airway for ventilation would lead to air leak.All patients had a reinforced laryngeal mask airway inserted after induction of anesthesia; anesthesia was ...

One of the main origins of unsuccesful endodontic treatment is coronal leakage. In the prevention of coronal leakage a good sealing restoration seems mandatory. The effect of 2 types lining cement used as coronal barrier on filled root canals was studied over time.
