Initial periodontal therapy may be helpful for diminishing oxidative stress in periodontitis.

The use of T-PRF alone in sinus-lifting operations has successful clinical and histomorphometric results. Bone formation in the T-PRF group was accelerated to 4 months compared to allografts according to the histological results.

Aim: To evaluate clinical and biochemical effects of adjunctive systemic folic acid (FA) intake with scaling and root planing (SRP) in periodontitis treatment. Materials and methods: Sixty periodontitis subjects (30 per group) were randomly assigned into study groups and treated with either SRP + placebo (SRP + P) or SRP + folic acid (SRP + F). In addition to clinical parameters (plaque index [PI], gingival index [GI], probing pocket depth [PPD], clinical attachment level [CAL] and gingival recession [GR]), gingival crevicular fluid (GCF) samples were obtained at baseline and post-treatment (PT) periods (one (PT-1), three (PT-3) and six (PT-6) months) for C-reactive protein (CRP) and homocysteine (Hcy) evaluation.Results: Significant time-dependent reduction was detected at all clinical parameters for both groups (p < .001). Compared to SRP + P, CAL was lower in SRP + F at PT-1 (p = .004) and PT-3 (p = .035), whereas GR was lower at only PT-1 (p = .015). GCF volume and CRP did not show inter-group differences, whereas Hcy was higher in SRP + F at PT-3 (p = .044) and PT-6 (p = .041). GCF volume and Hcy showed reduction after treatment in both groups (p < .001). Conclusion: Both modalities exhibited clinical improvement and change in biochemical parameters. Adjunctive systemic FA intake may be recommended adjunctive to periodontitis treatment to reveal better outcomes. However, its impact mechanisms should be further enlightened.

Objective:In general, chemical plaque agents have been used in mouthwashes, gels, and dentifrices. In some situations, application of mouthwashes and dentifrices can be difficult. Therefore, different approaches for oral health-care have been needed. The aim of this study was to evaluate the effect of propolis chewing-gum compared to propolis-containing mouthwash on gingival inflammation and plaque accumulation on patients that refrained from daily oral hygiene procedures for 5 days.Materials and Methods:10 college students with systemically healthy and very good oral hygiene and gingival health were included in this randomized, single-blind, crossover 5-day plaque regrowth with a 3-day washout period clinical study. After plaque scores were reduced to zero, participants were asked to refrain from oral hygiene procedures and allocated to either propolis mouthwash or chewing-gum group. Chewing-gum was performed after meals 3 times a day for 20 min mouthwash group was instructed to rinse mouthwash 2 times a day for 1 min. On day 5, the clinical periodontal measurements containing plaque and gingival indexes were taken from the participants.Results:The both plaque and gingival indexes of propolis mouthwash group were significantly lower than that of the propolis chewing-gum group (P = 0.005).Conclusion:It was demonstrated that the propolis mouthwash was more effective than the propolis chewing gum on the plaque inhibition and the gingival inflammation.

Background There are limited studies to date investigating vitamin D and fibroblast growth factor (FGF)‐23 in different peri‐implant conditions. Purpose To evaluate the peri‐implant sulcus fluid (PISF) FGF‐23 and 25‐hydroxy‐vitamin D3 (25(OH)D3) levels in peri‐implant health and diseases. Materials and Methods A total of 90 dental implant sites (peri‐implant healthy group [n = 30], peri‐implant mucositis group [n = 30], and peri‐implantitis group [n = 30]) in 53 participants were included in the study. Probing depth (PD), clinical attachment level (CAL), suppuration (S), modified plaque index (mPI), gingival index (GI), modified sulcus bleeding index (mSBI), and keratinized mucosa width (KMW) were recorded as clinical parameters, and PISF samples were obtained. FGF‐23 and 25(OH)D3 levels were analyzed by enzyme‐linked immunosorbent assay. Results There were no statistically significant differences in FGF‐23 concentrations among the groups (P > .05). The 25(OH)D3 concentration was significantly lower in peri‐implantitis group compared with the other two groups (P < .05). The mean total amount of FGF‐23 in the peri‐implantitis group was significantly higher than the peri‐implant healthy group whereas 25(OH)D3 total amount was significantly lower in the peri‐implantitis group than the peri‐implant healthy group. The 25(OH)D3 concentration was significantly negatively correlated with CAL, PD, mPI, S, GI, and mSBI and statistically significant relationship was found between FGF‐23 total amount and these clinical parameters (P < .05). There was a negligible positive correlation between 25(OH)D3 and FGF‐23 concentrations (τ = 0.169; P = .018). Conclusion Within the limitations of this study, it can be concluded that FGF‐23 and vitamin D seems to affect peri‐implant bone health, and further studies are needed to explain the association between FGF‐23 and 25(OH)D3 in peri‐implant conditions.
