Abstract

Purpose: This study was conducted to evaluate the correlation of taste threshold with chewing patterns and condition of dentition in healthy adults in their 20s and 30s.
Materials and Methods: The subjects for this study consisted of 65 adults (43 males, 22 females; average age, 30.5±3.2 years). Upon receiving informed consent, all patients underwent oral examination to determine their dentition condition. In addition, chewing patterns were surveyed and a taste threshold test was administered using an electrogustometer (Model EG-IIB; Nagashima Medical Instrument Co., Tokyo, Japan).
Results: Taste threshold values differed significantly between the bilateral and unilateral chewing groups, as well as between the bilateral and right side chewing groups. The number of restorations on the right side was correlated with taste threshold on the right and left posterior area of the tongue. There was also a correlation between the number of restorations on the left side and taste threshold on the right posterior area of the tongue.
Conclusion: Bilateral mastication is desirable to prevent weakening of gustation; however, additional studies involving all age groups are required to provide more detailed classifications of the conditions of missing teeth or dental restorations and their relationship with taste.
