“…Electromotive forces of such galvanic cells depend on difference in standard potentials of metallic dental materials and oral mucosa. The consequent production of electrogalvanic currents and corrosion of dental materials is responsible for unpleasant symptoms and local lesions in the oral cavity [3].…”

“…Clinical symptoms include a discomforting sensation in the teeth or even sharp pain, when the current exceeds 20 lA [4]. The experience of acute galvanic shock is familiar to patients when new amalgam fillings contact old restorations or metallic crown [3,5]. The shock sensation is due to a transfer of electrons between metals of different standard electrochemical potential in an electrolyte (saliva).…”

“…These cases can be treated by physical separation of the restorations e.g. : by coating the entire surface of the restoration with composite resin [3].…”

“…It can be a reason of unpleasant metallic "tinfoil like" taste and burning feeling. As a consequence of exposure to metal ions such as mercury, copper and tin, some patients apart from local sensations report distant symptoms such as headache, vertigo, nausea, symptoms from stomach, eyes, throat and ears [3].…”

“…The signs associated with the phenomenon of chronic, asymptomatic, low-grade galvanism are erythema of oral mucosa, ulcerations, reddening at the apex of the tongue, geographic tongue, lichenoid reactions observed mainly in patients with amalgam fillings [3,6]. According to some reports contact allergy to mercury compounds may be responsible for inducing such lesions [7].…”

The work was aimed at studying of standard potentials of commonly used metallic dental materials and determining of the effect of saliva conductivity and reaction on value of the potentials. The following materials have been examined: gold alloy (a material used for crowns and bridgeworks), chromium-cobalt alloy (for frameworks in removable partial dentures), and silver amalgams (used for fillings) manufactured by three different companies.Taking into account that mucosa makes one of the electrodes existing in oral cavity the rest potentials of mucosa have been in vivo measured in several patients. Their values, converted with respect to NHE, oscillated within the range from þ 0.31 V to þ 0.47 V.Among metallic dental materials examined in the experiment maximal standard potential was found for the gold alloy, further materials having lower potentials, in decreasing order, were chromium-cobalt alloy, and the amalgams Amalcap Plus, ANA 2000 and Septalloy.Significant differences between standard potentials of examined materials and mucosa indicate spontaneous formation of galvanic cells of electromotive force reaching even about 0.6 V.

Background/purposeOver 250 years has been researched over the consequences of oral galvanism. Previous studies have already examined the influence on dental fixation materials. The aim of this study was to investigate the electro-chemical solubility behavior of different dental core build-up materials in a pseudo-realistic galvanic experimental setup.Materials and methodsThe composite Admira (Voco, Cuxhaven, Germany) and two glass ionomer cements, Ketac Molar and Photac (3M-Espe, Seefeld, Germany), were examined. Test specimens were exposed to electric field strengths of 10–27 V/m in 0.9% saline solution. After 1, 2, 3, and 24 h, 2 ml of the electrolyte was removed for analysis. Aluminum and calcium were selected as parameters to measure the solubility of the products. Differences between the test samples and controls were ascertained using the two sample t-test.ResultsFor all of the test groups, Admira demonstrated minimal solubility compared to Ketac and Photac. However, after 24 h in an electric field of 27 V/m, Admira demonstrated the highest increase in solubility compared to the controls (3.47 vs control at 0.76 μmol/l). The second highest increase yielded the conventional glass ionomer cement Ketac (8.62 vs control at 5.28 μmol/l), and a minor increase in solubility showed the composite-based glass ionomer material Photac (38.73 vs control at 31.78 μmol/l) compared to the controls.ConclusionThis study demonstrated that galvanic processes increase the solubility of glass ionomer and composite. Therefore, the time of storage, electric field strength, and contact of the material with the electrodes significantly influenced their solubility.
