ABSTRACT


Aim

This study was performed to evaluate the effect of a glucose rinse and of plaque accumulation on pH of tooth
surface in healthy adolescents with a device used in gastroenterology and never tested in the oral cavity. MATERIALS AND

Methods

Values of pH were monitored in 12 adolescents using a portable device (pH-day 2 Menfis, bioMedica S.r.l.,
Bologna, Italy) with a disposable antimonium electrode kept in contact with the interproximal surface of the upper molars for
40 minutes respectively before and after a one-minute rinse with 10 ml of a 10 glucose solution. The same procedure
was repeated in the same subjects after 72 hours of plaque accumulation.

Results

The device tested resulted difficult to
use on the tooth surface because of the size of the active part of the probe. The glucose rinse caused a statistically significant
decrease of the mean pH, restrained in basal conditions (d -0.16, p <0.05), clinically relevant after plaque accumulation (d -1.24, p <0.05). Time in minutes of pH < 6 grew considerably only in case of combination of plaque accumulation and glucose rinse (d 20.90, p <0.05). A Stephan's curve of drop and recover of the pH values was not recorded. CONCLUSIONS: The continuous recording of pH of natural plaque present on the tooth could represent an alternative to other techniques found in literature. More studies are necessary to verify the suitability of this new device for the monitoring of pH in the oral cavity.
