Histological evaluation of a biomimetic material in bone regeneration after one year from graft

The use of substitute materials is one of the solutions used in periodontology for the reconstruction of intrabony defects. Advances in scientific research gave rise to a new generation of biomaterials of synthetic origin stoichiometrically unstable and therefore really absorbable. Our research is directed precisely towards a bio-material synthesis, Engipore® (Finceramica, Faenza, Italy) which is a bone substitute of the latest hydroxyapatite-based generation, that possesses chemical and morphological properties similar to those of natural bone in the treatment of infrabony periodontal defects. Aim of this study was to evaluate the efficacy of Engipore® in the treatment of intrabony periodontal defects. The study was conducted on 100 parodontopatics patients, which had gingival pockets of at least infrabonies 8/10 mm. The histological evaluation was performed with samples after one year from the graft. The histological samples collected after one year showed an abundant new bone formation, with mature lamellar bone tissue surrounding the residual particles of Engipore® that appear completely osteointegrated. The surrounding connective tissue shows no signs of inflammation. The results obtained in our research demonstrated that, after a proper selection of patients and lesions, and applying an adequate surgical technique, this type of biomaterial in the treatment of periodontal defects acts in an optimal manner as a filler inducing the formation of new bone as evidenced by histological examinations

Effectiveness of a diode laser in addition to non-surgical periodontal therapy: study of intervention

Chronic periodontitis affects 47% of adult population over the age of 30. The first phase of periodontal treatment is always represented by scaling and root planning (SRP), that is a causal, non-surgical therapy that recognizes as primary aims the control of bacterial infection and the reduction of periodontal plaque-associated inflammation. Yet, another innovative causal therapy is represented by the irradiation of periodontal pockets with laser. To evaluate the effect of a 940-nm diode laser as an adjunct to SRP in patients affected by periodontitis. Sixty-eight adult patients with moderate-to-severe periodontitis were sequentially enrolled and undergone to periodontal examination (V1) in order to detect gingival index (GI), plaque index (PI) and probing depth (PD). The patients were randomly divided into two groups: the first (n=34) received SRP treatment alone, the control group (n=34) received SRP and 940-nm diode laser therapy. Data were analyzed by Student’s t-test, with two tails; for all clinical parameters, both groups reported statistically significant differences compared to basal values (p<0.0001). Both procedures were effective in improving GI, PI and PD, but the use of diode laser was associated with more evident results. Considered the better clinical outcomes, diode laser can be routinely associated with SRP in the treatment of periodontal pockets of patients with moderate-to-severe periodontitis
