Adhesive protocols may influence the success of resin composite restorations in CAD; this is important because failure can lead to caries, re-incidence, and/or clinical re-work.

Considering that the ability of DCs to regulate immunity is dependent on DC maturation, results suggest that predominance of imDCs appears to be involved in AgP pathogenesis, probably due to lack of ability to induce immune cell activation. Further studies are necessary to elucidate the role of DC maturation in regulating immune responses in periodontal disease.

NSPT had a beneficial impact on clinical and immunological parameters of CP, reduction of oral Candida counts, and improvement of HIV-infection status.

Background and Objective Some studies suggest that regulatory T cells (Tregs) have suppressive effects on inflammatory osteolysis. The aim of this study was to evaluate Treg immunomarkers in periodontitis‐affected tissues from patients with periodontitis and clinically healthy gingiva (control). Material and Methods The presence and distribution of positive cells for CD4, CD25 and FOXP3 (Treg immunomarkers) in periodontitis‐affected tissues (epithelium and lamina propria) of 30 patients (ten per group) with a diagnosis of stage IV, grade C periodontitis (IV‐C), stage III, grade B periodontitis (III‐B) and the control were evaluated. A two‐way ANOVA followed by Fisher's LSD test was used to demonstrate differences between the groups and immunomarkers; Student's t test was used to demonstrate differences between the epithelium and the lamina propria. Results Both IV‐C and III‐B periodontitis presented a significantly high proportion of immune‐stained cells for all immunomarkers when compared to the control group. Notably, CD25+ and FOXP3+ cells were detected in a significantly higher number in III‐B than IV‐C periodontitis (P < .05). Conclusion Our results suggest the participation of Tregs on the osteoimmunological mechanisms in IV‐C and III‐B periodontitis patients, notably contributing to strategies for alveolar bone regeneration in clinical treatment decisions.
