Abstract
Liquid biopsy is a noninvasive diagnostic technique used for monitoring cancer utilizing specific genetic biomarkers present in bodily fluids, such as blood, saliva, or urine. These analyses employ multiple biomolecular sources including circulating tumor DNA (ctDNA), circulating tumor cells (CTCs), and exosomes (that contain DNA fragments) to detect genetic biomarkers that can predict, disclose, and/or monitor cancers. Levels of these biomarkers can inform on the presence of cancer, its genetic characteristics, and its potential treatment response and also provide predictive genetic predisposition information for specific cancers including oral squamous cell carcinomas (OSCC). Liquid biopsies can aid cancer management as they offer real-time dynamic information on the response to say chemotherapy or radiotherapy and recurrence following surgical excision. Unlike traditional tissue biopsies, which are invasive with a degree of morbidity and require specific tumor location sampling, liquid biopsies are noninvasive and can be repeated frequently. For oral squamous cell carcinoma, on which this review focuses, liquid biopsy of blood or saliva can be valuable in predicting susceptibility, providing early detection, and monitoring the disease's progression and response to therapy. This review gives a general narrative overview of the technology, its current medical usage, and advantages and disadvantages compared with current techniques and discusses a range of current potential biomarkers for disclosing OSCC and predicting its risk. Oral squamous cell carcinoma is all too often detected in the late stages. In future, liquid biopsy may provide an effective screening process such that cancers including OSCC will be detected in the early stages rather than later when prognosis is poor and morbidity and debilitation are greater. In this screening process, periodontists and hygienists have a critical role in that they are adept in examining mucosa, they see patients with shared risk factors for periodontitis and OSCC, namely smoking and poor oral hygiene, and they see patients frequently such that OSCC examinations should be a routine part of the recall visit. With this additional screening manpower, oral medicine and oral surgery colleagues will detect OSCC earlier and this coupled with new techniques such as liquid biopsy may greatly decrease global morbidity in OSCC.

Abstract
OBJECTIVE This study aimed to investigate miRNA expression profiles in individuals with periodontitis which is a chronic inflammatory condition affecting the integrity of the periodontal attachment. miRNAs play a crucial role in gene regulation through various mechanisms, making them potential diagnostic markers and therapeutic targets for various diseases. MATERIALS AND METHODS A total of 25 individuals with aggressive periodontitis and 25 controls were included in the study. Gingival tissues were collected for miRNA isolation and cDNA synthesis. miRNAs associated with periodontitis, including hsa-miR-185-5p, hsa-miR-17, hs-miR-146a, hs-miR-146b, hs-miR-155, hs-miR-203, hs-miR-205, hs-miR-223, and hsa-miR-21-3p, were analyzed using a combination of miRTarBase database analysis and literature mining was performed. Real-time PCR was used to assess the expression patterns of the target miRNAs, and the data were analyzed using the REST program. RESULTS The study revealed upregulated expression levels of hsa-miR-223-3p, hsa-miR-203b-5p, hsa-miR-146a-5p, hsa-miR-146b-5p, and hsa-miR-155-5p in individuals with periodontitis. Conversely, downregulated expression was observed for hsa-miR-185-5p, hsa-miR-21-3p, and hsa-miR-17-3p. CONCLUSION The findings suggest significant differences in the expression of specific miRNAs associated with inflammation in periodontitis. MZB1 acts as a hormone-regulated adipokine/pro-inflammatory cytokine, driving chronic inflammation and influencing cellular expansion. Predominantly expressed in marginal zone and B1 B cells, specialized subsets that respond rapidly to infections, MZB1 impacts immune protein synthesis and immune cell maturation, notably targeting microRNA-185 to potentially impede T cell development. Further research is needed to elucidate the functional significance and potential implications of these miRNAs. CLINICAL RELEVANCE miRNAs regulate the expression of target genes by finely tuning protein expression levels. The current findings provide compelling evidence of notable variations in the expression levels of specific miRNAs associated with inflammation in individuals affected by periodontitis; hence, miRNAs hold promise as potential therapeutic targets for periodontitis.

Abstract
BACKGROUND Our previous study explored the molecular signatures of generalized aggressive periodontitis (GAgP) using gingival tissues through omics-based-whole-genome transcriptomic analysis. This continuation study aimed to investigate the whole protein profiling of these gingival samples through liquid chromatography-mass spectroscopy/mass spectroscopy (LC-MS/MS) analysis and to validate the identified proteins through immunohistochemistry to provide further evidence for the quality of the results. METHODS In previous study, gene expression patterns were identified in gingival tissues from 23 GAgP and 25 control individuals. In the current study, comparative proteomic analysis was performed on isolated proteins from the same study groups using LC-MS/MS analysis. The data from the transcriptomics study published before and the proteomics data were integrated to reveal any common genes and proteins. Additionally, immunohistochemical analysis was conducted to further investigate the findings. RESULTS The most upregulated proteins in patients compared to controls were ITGAM, AZU1, MMP9, BPI, UGGG1, MZB1, TRFL, PDIA6, PRDX4, and PLG. The top six pathways associated with these proteins were involved in innate immune system, post-translational protein phosphorylation, interleukin-4 and -13 signaling, toll-like receptors cascades, and extracellular matrix organization. Based on the integration and validation analysis of transcriptomics and proteomics data, as well as immunohistochemical analysis, MZB1 was identified as a shared gene and protein that were upregulated in the patients. CONCLUSIONS MZB1 is a protein that is involved in the development of B cells and the production of antibodies. Its upregulation in periodontitis suggests that there may be a dysregulation of the immune response in this condition, and MZB1 may be a potent biomarker for periodontitis.

Abstract
The aim of this study was to compare two different imaging methods by assessing changes caused by sodium bicarbonate and glycine air polishing on the tooth surfaces. Fourteen single root teeth with exposed root surfaces were included into the study. The teeth were randomly divided into two groups: sodium bicarbonate and glycine group. Samples were scanned in a micro-computed tomography (micro-CT) and CAD/CAM (computer-aided design/computer-aided manufacturing) at baseline and then after air-polishing powder applications, the defect volume values were evaluated. There was a statistically significant difference between mean defect volume values that occurred after glycine and sodium bicarbonate air polishing evaluated with micro-CT and CAD/CAM (p < 0.05). After sodium bicarbonate air polishing, defect volume on enamel surface at maximum power and defect volume on the exposed root surface at medium power values calculated with CAD/CAM were higher. After glycine air polishing, defect volume values on both surfaces at medium power setting calculated with CAD/CAM were lower. Defect volume values on enamel surface at maximum power setting calculated with CAD/CAM were higher than calculated with micro-CT. We concluded that CAD/CAM cannot provide as accurate results as micro-CT. Glycine-based powder is less abrasive than sodium bicarbonate, especially on enamel surface. Lay Description: Micro-CT is a non-destructive imaging method with high resolution and allows to examine all tooth structures individually. CAD/CAM are systems that are widely used in dentistry today. Access to the device is easier than micro-CT. Intraoral scanners in CAD/CAM systems also provide non-destructive image scanning. The aim of this study was to compare two different imaging methods by assessing changes caused by sodium bicarbonate and glycine air polishing on the tooth surfaces. The results showed that because of the analyses made with CAD/CAM, similar results could not be obtained with micro-CT and cannot be used to evaluate the changes that occur after air polishing.

Abstract
PURPOSE To evaluate the inflammation-related adipokine levels in the body fluids of obese female participants with and without periodontitis using healthy participants as a control group. METHODS A cohort design study was carried out at Kocaeli University between December 2014 and June 2015. The study sample comprised 25 obese female participants with periodontitis (Group 1), 31 obese female participants without periodontitis (Group 2), and 15 lean female participants with healthy periodontium (Group 3), from whom body mass index, clinical periodontal parameters were measured, and serum, saliva, and gingival crevicular fluid (GCF) samples were collected. The three groups' periodontal parameters and adipokine levels were evaluated and compared, and the primary outcome was the difference in local and systemic adipokine levels between the study groups. RESULTS In the participants' serum samples, tumor necrosis factor-α (TNF-α) and leptin levels were lower, whereas adiponectin levels were significantly higher in Group 3 than in the obese groups (P< 0.05). In the participants' saliva samples, interleukin-1β, TNF-α, and resistin levels were lowest in Group 3, but adiponectin was lowest in Group 2 (P< 0.05). In the participants' GCF samples, interleukin-1β, resistin, and adiponectin levels were higher in Group 1 (P< 0.05). This study showed that the amounts of the adipokines could differ in serum, saliva, and GCF samples from obese female participants with and without periodontitis and from lean female participants with healthy periodontium. CLINICAL SIGNIFICANCE Periodontal diseases in different severities can affect overall health by altering the amounts of adipokines (IL-1β, TNF-α, leptin, resistin, and adiponectin) in serum, saliva, and GCF of obese female patients. Clinicians should be aware that periodontal disease can alter inflammatory adipokine levels and may affect other treatment outcomes in obese female patients.

Abstract
Background Several studies have demonstrated an association between obesity, periodontitis, and exercise. Aims This study aimed to investigate the effects of regular exercise on obese women with periodontal disease, using serum, saliva, and gingival crevicular fluid (GCF) samples. A before-after study design was adopted to evaluate the effects of 12 weeks of regular exercise on obese women grouped according to periodontal status, without a control group (no exercise). The study sample comprised of 15 patients without periodontitis (NP group) and 10 patients with chronic periodontitis (CP group), from whom periodontal parameters were measured and serum, saliva, and GCF samples were collected. Body mass index (BMI), anthropometric measurements, somatotype-motoric tests, and maximal oxygen consumption (VO2max) were recorded at baseline and after exercise. Subjects and Methods Med Calc was used for statistical analysis. Results After exercise, a significant decrease in BMI and a significant increase in VO2max were observed in both groups. A significant decrease in probing depth and clinical attachment loss, serum leptin, GCF tumor necrosis factor-α(TNF-α) and leptin, and a significant increase in GCF resistin were observed in the CP group. A significant decrease in serum TNF-α and leptin levels and a significant increase in serum resistin and GCF TNF-α, leptin, resistin, and adiponectin levels were observed in the NP group. Significant correlations between bleeding on probing and levels of interleukin-1β and leptin in GCF were observed in the CP group. Conclusions This study showed that regular exercise exerts different impacts with respect to clinical and biochemical aspects of periodontal and systemic conditions in obese women.

Abstract
BACKGROUND To elucidate molecular signatures of chronic periodontitis (CP) using gingival tissue samples through omics-based whole-genome transcriptomic and whole protein profiling. METHODS Gingival tissues from 18 CP and 25 controls were analyzed using gene expression microarrays to identify gene expression patterns and the proteins isolated from these samples were subjected to comparative proteomic analysis by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The data from transcriptomics and proteomics were integrated to reveal common shared genes and proteins. RESULTS The most upregulated genes in CP compared with controls were found as MZB1, BMS1P20, IGLL1/IGLL5, TNFRSF17, ALDH1A1, KIAA0125, MMP7, PRL, MGC16025, ADAM11, and the most upregulated proteins in CP compared with controls were BPI, ITGAM, CAP37, PCM1, MMP-9, MZB1, UGTT1, PLG, RAB1B, HSP90B1. Functions of the identified genes were involved cell death/survival, DNA replication, recombination/repair, gene expression, organismal development, cell-to-cell signaling/interaction, cellular development, cellular growth/proliferation, cellular assembly/organization, cellular function/maintenance, cellular movement, B-cell development, and identified proteins were involved in protein folding, response to stress, single-organism catabolic process, regulation of peptidase activity, and negative regulation of cell death. The integration and validation analysis of the transcriptomics and proteomics data revealed two common shared genes and proteins, MZB1 and ECH1. CONCLUSION Integrative data from transcriptomics and proteomics revealed MZB1 as a potent candidate for chronic periodontitis.

Abstract
Periodontitis is one of the most common inflammatory diseases, with a prevalence of 11% worldwide for the severe forms and an estimated heritability of 50%. The disease is characterized by destruction of the alveolar bone due to an aberrant host inflammatory response to a dysbiotic oral microbiome. Previous genome-wide association studies (GWAS) have reported several suggestive susceptibility loci. Here, we conducted a GWAS using a German and Dutch case-control sample of aggressive periodontitis (AgP, 896 cases, 7,104 controls), a rare but highly severe and early-onset form of periodontitis, validated the associations in a German sample of severe forms of the more moderate phenotype chronic periodontitis (CP) (993 cases, 1,419 controls). Positive findings were replicated in a Turkish sample of AgP (223 cases, 564 controls). A locus at SIGLEC5 (sialic acid binding Ig-like lectin 5) and a chromosomal region downstream of the DEFA1A3 locus (defensin alpha 1-3) showed association with both disease phenotypes and were associated with periodontitis at a genome-wide significance level in the pooled samples, with P = 1.09E-08 (rs4284742,-G; OR = 1.34, 95% CI = 1.21-1.48) and P = 5.48E-10 (rs2738058,-T; OR = 1.28, 95% CI = 1.18-1.38), respectively. SIGLEC5 is expressed in various myeloid immune cells and classified as an inhibitory receptor with the potential to mediate tyrosine phosphatases SHP-1/-2 dependent signaling. Alpha defensins are antimicrobial peptides with expression in neutrophils and mucosal surfaces and a role in phagocyte-mediated host defense. This study identifies the first shared genetic risk loci of AgP and CP with genome-wide significance and highlights the role of innate and adaptive immunity in the etiology of periodontitis.

Abstract
BACKGROUND In this study, molecular biomarkers that play a role in the development of generalized aggressive periodontitis (GAgP) are investigated using gingival tissue samples through omics-based whole-genome transcriptomics while using healthy individuals as background controls. METHODS Gingival tissue biopsies from 23 patients with GAgP and 25 healthy individuals were analyzed using gene-expression microarrays with network and pathway analyses to identify gene-expression patterns. To substantiate the results of the microarray studies, real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was performed to assess the messenger RNA (mRNA) expression of MZB1 and DSC1. The microarrays and qRT-PCR resulted in similar gene-expression changes, confirming the reliability of the microarray results at the mRNA level. RESULTS As a result of the gene-expression microarray studies, four significant gene networks were identified. The most upregulated genes were found as MZB1, TNFRSF17, PNOC, FCRL5, LAX1, BMS1P20, IGLL5, MMP7, SPAG4, and MEI1; the most downregulated genes were found as LOR, LAMB4, AADACL2, MAPT, ARG1, NPR3, AADAC, DSC1, LRRC4, and CHP2. CONCLUSIONS Functions of the identified genes that were involved in gene networks were cellular development, cell growth and proliferation, cellular movement, cell-cell signaling and interaction, humoral immune response, protein synthesis, cell death and survival, cell population and organization, organismal injury and abnormalities, molecular transport, and small-molecule biochemistry. The data suggest new networks that have important functions as humoral immune response and organismal injury/abnormalities. Future analyses may facilitate proteomic profiling analyses to identify gene-expression patterns related to clinical outcome.

Abstract
Background The objective of this randomized clinical study was to evaluate the effect of systemic administration of moxifloxacin compared to amoxicillin and metronidazole, combined with non-surgical treatment in patients with generalized aggressive periodontitis (GAgP) in a 6-month follow-up. Material and Methods A total of 39 systemically healthy patients with GAgP were evaluated in this randomized clinical trial. Periodontal parameters were recorded at the baseline during the 1st, 3rd and 6th month. Patients received either 400 mg of moxifloxacin per os once daily or 500 mg of metronidazole and 500 mg amoxicillin per os three times daily for 7 days consecutively. Results No significant differences between groups were found in any parameters at the baseline. Both groups led to a statistically significant decrease in all clinical periodontal parameters compared to the baseline (PI, p<0.001 and GI, PD, BOP, CAL, p<0.01). There were no differences between the 1st and 3rd months or the 3rd and 6th months for clinical parameters in the groups. Also, no intergroup difference was observed in any parameters at any time, except the gingival index at 6th months. Conclusions Systemic administration of moxifloxacin as an adjunct to non-surgical treatment significantly improves clinical outcomes and provides comparable clinical improvement with less adverse events to that of combination of amoxicillin and metronidazole in the treatment of GAgP. Key words:
Aggressive periodontitis, amoxicillin, metronidazole, moxifloxacin, nonsurgical periodontal debridement.

Abstract
Peripheral giant cell reparative granuloma is a reactive and rare lesion of oral cavity with unknown etiology which is derived from periosteum and periodontal ligament and occurs frequently in young adults. Inflammation or trauma is underlying causative factor of reactive proliferation. In the present case report, a 35 year-old male with aggressive periodontitis and peripheral giant cell reparative granuloma is presented. The patient applied to our clinic with a complaining about a big nodule at his palate. The lesion was pedunculated and localized at his right maxilla between #16 and #17 which arose from distal aspect of #16, and the surface of the lesion was hyperkeratotic and the lesion was measured 22 x 30 mm at the largest diameter. He also had severe generalized aggressive periodontitis and hypertension. Amoxicillin clavulanate 625 mg, three times a day, metronidazole 500 mg three times a day and 0.2% chlorhexidine digluconate oral rinse, twice a day for a week, were prescribed to the patient. Then, scaling and root planing were performed along with systemic antibiotic treatment and he scheduled for surgery. The lesion was excised completely and #16 was extracted. After the healing period, periodontal surgery was planned for the treatment of aggressive periodontitis. Obtained tissue specimen was sent for histopathological examination. The diagnosis of peripheral giant cell reparative granuloma was confirmed with histopathological examination. No intra- and post-operative complications were seen.

Abstract
AIM Many studies investigated the role of genetic variants in periodontitis, but few were established as risk factors. We aimed to validate the associations of recent candidate genes in aggressive periodontitis (AgP). MATERIAL AND METHODS We analysed 23 genes in 600 German AgP patients and 1441 controls on the Illumina custom genotyping array Immunochip. We tested a suggestive association in a Dutch and German/Austrian AgP case-control sample, and a German chronic periodontitis (CP) case-control sample using Sequenom iPlex assays. We additionally tested the common known risk variant rs1333048 of the gene ANRIL for its association in a Turkish and Italian population. RESULTS None of the analysed genes gave statistical evidence for association. Upon covariate adjustment for smoking and gender, in the pooled German-Austrian AgP sample, IL10 SNP rs6667202 was associated with p = 0.016, OR = 0.77 (95% CI = 0.6-0.95), and in the Dutch AgP sample, adjacent IL10 SNP rs61815643 was associated with p = 0.0009, OR = 2.31 (95% CI = 1.4-3.8). At rs61815643, binding of the transcription factor PPARG was predicted. ANRIL rs1333048 was associated in the Turkish sample (pallelic = 0.026, OR = 1.67 [95% CI = 1.11-2.60]). CONCLUSIONS Previous candidate genes carry no susceptibility factors for AgP. Association of IL-10 rs61815643 with AgP is suggested. ANRIL is associated with periodontitis across different populations.
