The purpose of this prospective observational study is to evaluate the relationship between preoperative sleep disturbances-specifically insomnia-and postoperative pain intensity following oral surgical procedures. Recent scientific literature highlights a bidirectional relationship between sleep disorders and pain in dentistry, suggesting that disturbed sleep may actively exacerbate subsequent pain perception. Although postoperative pain, swelling, and masticatory difficulties are common after dental extractions, clinical data investigating the direct impact of preoperative sleep quality on these surgical outcomes remain scarce. This study will enroll adult patients undergoing routine dental extractions and allocate them into two cohorts based on their baseline sleep quality: patients without preoperative sleep disturbances and patients with preoperative sleep disturbances. Pain levels and sleep parameters will be assessed using validated questionnaires before the surgery and at a 7-day follow-up. The primary objective is to determine whether the presence of preoperative insomnia leads to a significant increase in perceived postoperative surgical pain.

In Odense University Hospital preoperative dental screening (PDS) protocol for patients treated with surgical valve replacement was changed from mandatory to targeted PDS to from march 2024. The investigators will therefore compare the risk of IE before vs after march 2024.

Deep marginal elevation usinge a bioactive dental material in deep subgingival Class II restorations, S-PRG filler-containing materials offer significant benefits due to their bioactive properties, Their ability to release fluoride, remineralization potential and acid neutralization, reducing the risk of recurrent caries, particularly at the gingival margin(Imazato et al. 2023). The antibacterial and antifungal effects help inhibit biofilm formation, enhancing the longevity of restorations. Additionally, these materials support better marginal adaptation by reducing microleakage and improving bond durability (Imazato et al. 2023) This type of composite may improve the outcomes of deep subgingival margin elevation, benefiting both restorative success and periodontal health(Imazato et al. 2023).

Using a bioactive resin composite in subgingival Class II cavities can provide enhanced caries resistance by releasing multiple ions, including fluoride. This approach offers greater resistance to caries due to the incorporation of surface pre-reacted glass filler (S-PRG) technology (Imazato, Nakatsuka et al., 2023). This type of composite may improve the outcomes of deep subgingival margin elevation, benefiting both restorative success and periodontal health.
