摘要

Selecting adequate restorative dental materials capable of tolerating the unfavourable long-term side effects on oral health following head and neck cancer radiotherapy patients is still of concern among researchers and clinicians.

The objective of this study was to evaluate the clinical performance of multi-ion releasing composite, glass ionomer, and composite resin in erosive tooth wear on post-head and neck radiotherapy patients during a one-year follow-up.

Twelve teeth with erosive wear lesions from four head and neck cancer patients were restored, each with one of the following restorative materials: a nano-filled composite resin, an encapsulated conventional glass ionomer, or a multi-ion releasing composite. All patients had previously undergone radiotherapy. The patients' salivary flow was measured in stimulated and non-stimulated methods. Their restorative clinical performance was double-blindly and regularly evaluated for 12 months according to the international dental federation and modified United States Public Health Service criteria and then correlated with all patients' registered salivary flow.

These case reports highlight the impact of different clinical scenarios considering different salivary flows on restorative clinical performance. The multi-ion releasing composite performed more similarly to the nanofiller composite resin than the glass ionomer.
