Description

<p>Purpose: The purpose of this study was to clarify the influence of the use of denture adhesive containing alcohol (home reliner) on breath alcohol concentration (BAC) through in vitro and in vivo experiments.</p><p>Methods: In the in vitro study, five materials—three kinds of denture adhesives and two tissue conditioners—were examined. The diffusion of alcohol odor was measured over time using a semiconductor odor sensor when each specimen was placed in a semi-closed space simulating the oral cavity. In the in vivo study, healthy young subjects were asked to wear the palatal plates lined with each denture adhesive or tissue conditioner, and the BAC was measured over time with an alcohol detector. One denture adhesive and one tissue conditioner were examined. Furthermore, the palatal plate was removed 5 minutes later after wearing and the BAC after removal was also measured.</p><p>Results: In the in vitro study, the odor intensity remained without much reduction one hour later and increased in proportion to the area exposed to the air. In the in vivo study, the BAC was the highest immediately after wearing, and exceeded 0.15 mg/L, which is the threshold for drunken driving, during 5 minutes after wearing. However, the BAC decreased with time, and was 0 mg/L 30 minutes later. The BAC in the lining with denture adhesive was significantly higher than that of tissue conditioner. Although the BAC transiently increased after removing the palatal plate, it became 0 mg/L 10 minutes later.</p><p>Conclusion: The use of denture adhesive containing alcohol influenced the BAC. It is suggested that the appropriate use and removal of the denture could reduce the increase of BAC.</p>
