The purpose of this study was to investigate the effect of ultrasonic scaling on teeth restored with a light‐cured resin. Ultrasonic scaling is a very popular periodontal therapy among dentists, and used for the removal of dental plaque and calculus in order to reduce and eliminate inflammation. Given the fact that most ultrasonic devices are used at high frequencies to perform scaling, undesirable consequences, such as loss of adhesion and increase in surface roughness, may occur in teeth that have been restored with light‐cured resins. Electrochemical impedance spectroscopy ( EIS ) and scanning electron microscopy were used to investigate the effects of ultrasonic treatments at the dental material–hard dental tissue interface. After ultrasonic scaling, EIS measurements were performed on a human tooth that had been restored with a light‐cured resin filling. The data were analyzed and the influence of ultrasound was shown after visualization of the hard dental tissues and the dental material as equivalent electrical circuits. The study revealed, through EIS measurements, that ultrasonic scaling affected the resistance of the light‐cured resin filling and dentin, whereas the enamel was affected only slightly. Scanning electron microscopy revealed an increase in roughness of the dental material.
