A 32-year-old female patient presented at our dental practice complaining of painful sensitivity in certain teeth after these teeth had been treated with composite restorations. Clinical and radiological examinations and the vitality test reported some composite and amalgam restorations which were visibly not sealed and displayed secondary caries. The decision was taken to renew these fillings. However, as it is not possible to make a conclusive assessment of the pulp in the case of teeth with pain symptoms, we decided on a temporary restoration of the cavity with the glass ionomer restorative IonoStar Molar (VOCO) followed by a 40-day monitoring period.
