Abstract
BACKGROUND The study aimed to analyze cytokine levels, including interleukin (IL)-1β, IL-10, and IL-36γ, to investigate the link between pro- and anti-inflammatory responses in periodontal conditions and assess their potential as diagnostic biomarkers for distinguishing between different types of periodontal conditions. METHODS 80 systemically healthy non-smokers (25 periodontally healthy, 25 with gingivitis, 30 with periodontitis) were included. Clinical periodontal parameters were recorded, and gingival crevicular fluid (GCF) samples were obtained. Receiver operating characteristic (ROC) curve analysis was applied to determine the diagnostic value of cytokines. RESULTS IL-36γ had the highest sensitivity for diagnosing periodontitis, although its specificity for identifying those without periodontitis was relatively low. The combination of IL-1β and IL-36γ was the most effective in differentiating periodontitis from periodontal health. IL-10 was found to be an acceptable discriminator for distinguishing gingivitis from healthy conditions. However, its sensitivity and specificity for identifying gingivitis were lower. The combination of the three cytokines showed the highest ability to distinguish between periodontitis and gingivitis. CONCLUSION The levels of IL-1β, IL-10, and IL-36γ in GCF may provide insights into periodontal health and disease status. Further studies are needed to validate these results and explore the potential of these cytokines in periodontal disease management.

Abstract
OBJECTIVE The compatibility of digital and analog methods assessing the positions of gingival zenith (GZ) points has not been evaluated before. Therefore, the aim of this study was to investigate the accuracy of a digital scanner and a three-dimensional (3D) measuring tool in specifying positions of GZs by comparing it to the conventional method, an analog plaster cast and a caliper. MATERIALS AND METHODS Both analog and digital impressions were obtained from 32 individuals. Following measurements were conducted in the anterior maxillary region from canine to canine on both the plaster casts and 3D images: (1) The distance from GZ to the corresponding vertical midline in each tooth (GZVM), (2) The distance from GZ of lateral incisor to the corresponding tangent that connects GZs of central incisor and canine (GZLI). RESULTS The intraclass correlation coefficients (ICC) of GZVM in each tooth varied between 0.366 and 0.755, demonstrating moderate to good compatibility between the two methods. The ICC of analog and digital GZLI for the right and left lateral incisors was 0.788 and 0.395, respectively. CONCLUSION The digital and analog methods used in this study are compatible in determining the positions of GZs. Therefore, within the limitations of the present study, the choice of method can be based on the available equipment, time, comfort, and personal preference of the researcher. CLINICAL SIGNIFICANCE Both digital and analog methods have the capability of determining the positions of GZs in compatible way.

Abstract
ABSTRACTObjectives: Lactoferrin (LF) is an iron binding protein and stored in the specific granules of granulocytes. It is released by degranulation following granulocyte activation. A positive correlation was previously reported between periodontitis and LF titers of gingival crevicular fluid (GCF) and blood. The purpose of this study was to examine alterations of GCF and blood levels of LF (LF-GCF and LF-BL, respectively), employing the experimental gingivitis model.Methods: Twelve systemically healthy volunteers, aged 19-21, were selected. Pre-experimental phase of hygiene was followed by a 14-day experimental gingivitis phase in which subjects refrained from all oral hygiene procedures. After that subjects resumed optimal plaque control for 21 days of recovery period. At days 0 (baseline), 14 and 35 gingival crevicular fluid (GCF) and blood samples were collected and plaque index (PI), gingival index (GI), bleeding on probing (BOP) and probing pocket depth scores were recorded. LF levels were measured with commercial enzyme-linked immunosorbent assay (ELISA) kit.Results: PI, GI, BOP and LF-GCF increased significantly after 14 days of experimental gingivitis period and decreased significantly after reinstitution of oral hygiene measures (P<.05). LF-BL appeared to follow the same pattern. Significant negative correlation was detected between the level of LF-BL and BOP at day 14 (P<.05), whereas significant positive correlation was noticed between LFBL and clinical scores PI, GI and BOP at day 35 (P<.05).Conclusions: LF-BL followed the same pattern with LF-GCF and clinical scores during the experimental gingivitis and recovery periods, although alterations of the LF-BL appeared statistically insignificant.

Abstract
Background/purpose The application of ozone as an adjunctive treatment represents a new approach in the management of chronic periodontitis. The purpose of this study was to evaluate the clinical, biochemical and microbiological efficacy of ozone treatment as an adjunct to scaling and root planing (SRP) in generalized chronic periodontitis (GCP) patients. Materials and methods Eighteen patients (9 males and 9 females; aged from 28 to 47 years, mean age of 40 ± 6.51 years) with GCP were recruited in the study. In a split mouth design, two quadrants in each patient were randomly allocated to SRP-alone or SRP-ozone therapy (SRP + OT) groups by coin toss method. Subgingival plaque and gingival crevicular fluid (GCF) samples were collected at baseline, following 1st and 3rd months. The clinical parameters were monitored at baseline and after 3 months. Microbiological parameters were analyzed by quantitative-PCR and GCF biomarkers were determined by ELISA. Results were analyzed statistically. Results Statistically significant improvements in all clinical parameters were accompanied by a reduction in microbiological and biochemical parameters in both treatment groups. SRP treatment resulted in a significant reduction of Porphyromonas gingivalis (Pg) at 1st month and Tannerella forsythia (Tf) and Prevotella intermedia (Pi) at 3 months. Following SRP treatment the interleukin (IL)-8 levels were significantly reduced at month 1. There were no significant differences between two treatments for any of the parameters. Conclusion Within the limitations of this study, adjunctive ozone therapy did not provide additional benefits to clinical, microbiological and biochemical parameters over SRP in chronic periodontitis patients.

Abstract
The aim of this study was to determine gingival crevicular fluid (GCF) expressions of tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), and tartrate-resistant acid phosphatase (TRAP) 5b in the mechanism of orthodontic tooth movement. Nine adolescents requiring canine distalization participated in the study. A canine undergoing distal movement served as the test tooth, and the contra-lateral canine served as the control. The clinical parameters were recorded and GCF samples were collected from the mesial and distal gingival crevices of teeth at baseline, 1 h, 24 h, 7 days, and 28 days following force application. GCF samples were analyzed using ELISA. The data were analyzed using three-way repeated measures analysis of variance. TNF-α and TRAP5b levels in distal and mesial sites of the test teeth were significantly higher than that at both sites of the controls. When compared with baseline values, increase was prominent at 1 h and 24 h. The IL-10 concentration decreased during experimental period at both sites of the control and test teeth. The results demonstrated that orthodontic forces evoke changes in the levels of TNF-α, IL-10, and TRAP5b during the initial stages of force application. The changes in local host response in periodontal tissues may be one of the triggers in regulating alveolar bone resorption during orthodontic tooth movement.

Abstract
OBJECTIVE The objective of this study was to histologically and histomorphometrically evaluate the efficacy of the new formulations of eggshell-derived calcium carbonate in rats. STUDY DESIGN The study was conducted on 30 adult male rats. Four standardized and circular intrabony defects were created in the both maxilla and mandibula of each animal. Three different graft materials were prepared as follows: 1) Material A: Eggshell-derived calcium carbonate combined with carrageenan gel, 2) Material B: Eggshell-derived calcium carbonate combined with xanthan gum gel, and 3) Material C: Eggshell-derived calcium carbonate powder. The right mandibular defect sites were grafted with Material A in all animals, and defects on the left were grafted with Material B. Defects on the right side of maxilla were received Material C in all animals, and all left maxillary defects were remained untreated as controls. The animals were sacrificed either postoperatively on the 15th day, postoperatively on the 30th day or postoperatively on the 45th day. Histomorphometric measurements were made of the areas of newly formed bone, necrotic bone, fibrous tissue and residual graft material. RESULTS Material A exhibited the highest level of osteoid formation followed by Material B and Material C on the 45th day. In terms of osteoid formation, statistically significant differences were observed between graft materials and controls at 45th day compared to 15th and 30th day (p<0.05). CONCLUSIONS Eggshell-derived graft substitutes in both gel and powder forms are biocompatible materials which may have the potential to enhance the new bone formation.

Abstract
BACKGROUND Smoking causes an increase in the thickness of gingival epithelium, which is the outcome of increased keratinocyte proliferation or loss. Smoking-related changes in the proliferative activity of the gingival epithelium are largely uncharacterized for periodontal diseases. The aim of the present study was to determine the effects of smoking on the proliferation of the epithelium in periodontally diseased marginal gingiva by comparing the expression patterns of two different proliferation markers. METHODS Gingival biopsies (N=60) were obtained from smokers who had clinically healthy gingiva (n=10), smokers with gingivitis (n=10), smokers with periodontitis (n=10), non-smokers with clinically healthy gingiva (n=10), non-smokers with gingivitis (n=10), and non-smokers with periodontitis (n=10). The quantitative measurement of maximum epithelial thickness was performed on hematoxylin and eosin-stained sections. The expression patterns for proliferating cell nuclear antigen (PCNA) and Ki67 were evaluated immunohistochemically. RESULTS The percentage of PCNA-positive cells was higher than the percentage of Ki67-positive cells in all groups (P<0.001). When the mean values of PCNA and Ki67 were compared in each group, a statistically significant difference was observed only in the healthy smoker group (P=0.003). Significant differences in PCNA proliferation indices were only found between the smoker group and the non-smoker healthy group (P=0.015). CONCLUSIONS Smoking had an affect on the proliferation of cells in the oral gingival epithelium, regardless of periodontal status. The increase in thickness of the epithelium was not associated with smoking; periodontal status and inflammation seemed to be more important factors. Smoking induced the replication activity of gingival epithelium and induced DNA repair.

Abstract
OBJECTIVES The aim of this study was to evaluate the effects of phase I periodontal treatment on gingival crevicular fluid (GCF) levels of matrix metalloproteinase (MMP)-3 and tissue inhibitors of metalloproteinase (TIMP)-1. METHODS Plaque index, gingival index, pocket depth and clinical attachment loss were recorded and GCF samples were collected from 20 chronic periodontitis (CP) patients and 20 periodontally healthy controls (C) before treatment. CP patients received phase I periodontal treatment and all clinical parameters were recorded and GCF samples were collected once more after treatment. Assays were performed by an enzyme-linked immunosorbent assay. RESULTS All of the clinical parameters improved significantly after the therapy (p<0.05). Baseline GCF levels of MMP-3 were significantly higher than C and that level was reduced significantly by treatment compared with baseline levels (p<0.05). Baseline GCF levels of TIMP-1 were lower than post-treatment levels and C (p<0.05). GCF levels of TIMP-1 increased significantly by treatment compared with baseline levels (p<0.05). CONCLUSION This study shows that the clinical improvements after phase I periodontal therapy are accompanied by reduction in MMP-3 and increasing in TIMP-1 GCF levels.
