BACKGROUND
The influence of maternal oral and dental health on the occurrence of Preterm Premature Rupture of Membranes (P-PROM) and its underlying mechanisms remain uncertain. This research seeks to investigate the impact of maternal oral and dental health on the incidence of P-PROM and its association with inflammatory markers in the blood.
METHODS
This study adopts a prospective case-control design methodology. The study involved 70 women diagnosed with P-PROM and delivered by an obstetrician and 79 women who had healthy deliveries with no prenatal complications. The values for DMFT (Number of decayed, missing and filled teeth) index, Gingival Index (GI), Plaque index (PI), Pocket depth (PD), Clinical attachment loss (CAL) and medical history were recorded. Mann-Whitney U test and hierarchical binomial logistic regression analysis were applied. It was considered statistically significant at p < 0.05.
RESULTS
The case group's DMFT, PI, GI, PD values were statistically significantly higher than the control group (p < 0.001). There was no relationship between DMFT, GI, PD, CAL and inflammatory blood markers (p > 0.05). In the regression analysis for possible risk factors that may be effective in P-PROM, oral and dental health parameters were the most effective.
CONCLUSIONS
Oral and dental health of women with P-PROM was found to be worse than that of the control group. Oral and dental health may be a potential risk factor that may contribute to adverse pregnancy outcomes associated with P-PROM.

BACKGROUND AND OBJECTIVE
Visfatin, a pleotropic mediator mostly produced by visceral fat, is crucial in controlling the immunological and defensive systems. It serves the roles of a cytokine, an enzyme involved in energy metabolism, and a growth factor. The objective of the present study was to assess the impact of non-surgical periodontal therapy (scaling and root planing) on visfatin concentrations in saliva and gingival crevicular fluid in individuals with Periodontitis (stage-II grade-A).
MATERIALS AND METHODS
54 individuals were divided into Group A (Periodontally Healthy) and Group B1(Periodontitis baseline) based on periodontal parameters including plaque index (PI), gingival index (GI), probing pocket depth (PPD), clinical attachment level (CAL), and radiographic parameters. After NSPT (SRP), Group B1 patients were recalled after 4 weeks, constituting Group B2 (post NSPT group B1). At baseline and 4 weeks after non-surgical periodontal therapy (SRP), all clinical parameters, salivary and GCF samples were recorded. An ELISA kit was used to measure the levels of visfatin. Using the paired -test, unpaired -test, and Pearson's correlation coefficient, data were analysed using SPSS 15.
RESULTS
After non-surgical periodontal treatment (SRP), the mean salivary and gingival crevicular fluid concentration of visfatin considerably decreased to a level comparable to periodontal health. In all groups, GCF visfatin concentration was higher than salivary concentration of visfatin. In periodontitis patients, visfatin concentration in GCF was 1.5 times higher than in saliva.
CONCLUSION
The results of this investigation suggest a direct correlation between salivary and gingival crevicular fluid visfatin concentration and periodontal tissue inflammation and disease activity.

BACKGROUND
Periodontal health in men with HIV remains understudied, despite suggestions of associations between HIV infection and gingival pocketing, periodontal attachment loss, and gingival inflammation. As antiretroviral therapy (ART) has improved the quality of life for people living with HIV (PLWH), aging-related risk factors and comorbidities, including periodontitis, have emerged. This study aims to assess alveolar bone height, gingival crevicular fluid (GCF) cytokines, and periodontal disease activity in men with and without HIV.
METHODS
Ninety-three men (50 HIV+, 43 HIV‒) aged 35-70 years were recruited from Columbia University Irving Medical Center clinics. Periodontal examination, GCF collection, and intraoral radiographs were conducted.
RESULTS
While no significant differences were observed in bleeding on probing, clinical attachment loss and pocket depths, men with HIV exhibited significantly greater alveolar crestal height on radiographs compared to men without HIV (HIV + 3.41+/-1.35 mm, HIV- 2.64+/-1.01 mm; p = 0.004), reflecting greater alveolar bone loss. GCF IL6 levels showed a trend towards elevation in men with HIV (HIV + 0.349+/-0.407 pg/ml, HIV- 0.220+/-0.228 pg/ml; p = 0.059).
CONCLUSIONS
Men with HIV demonstrate increased alveolar bone loss compared to those without HIV, possibly mediated by elevated IL6 levels. These results underscore the importance of comprehensive oral health management in PLWH and highlight the need for further research understanding the mechanisms linking HIV infection, cytokine dysregulation, and periodontal health.

Periodontitis is a common chronic infection and is associated with cardiovascular disease. This study evaluated whether basic oral care for periodontal disease could improve endothelial function in patients with acute coronary syndrome (ACS).This study enrolled 54 patients with acute coronary syndrome admitted to Kagoshima City Hospital and who had undergone percutaneous coronary intervention. Flow-mediated endothelium-dependent dilatation (FMD) was measured before discharge (initial FMD) and at 8 months after percutaneous coronary intervention (follow-up FMD). The following periodontal characteristics were measured: periodontal pocket depth (PPD, mm), plaque control record (%), and bleeding on probing (%). All patients received basic oral care instructions from dentists. The oral health condition was generally poor in the participants and there were 24 patients (44.4%) who had severe PPD. Despite the intervention of basic oral care, the periodontal characteristics did not improve during the study period; initial FMD and follow-up FMD did not significantly differ (4.38 ± 2.74% versus 4.56 ± 2.51%, P = 0.562). However, the follow-up FMD was significantly lower in patients with severe PPD (≥ 6.0 mm, n = 24) than in patients without severe PPD (≤ 5.0 mm, n = 30) (FMD: 3.58 ± 1.91% versus 5.37 ± 2.67%, P = 0.007). FMD tended to be worse in patients with severe PPD than in patients without severe PPD (ΔFMD: -0.55 ± 2.12 versus 0.81 ± 2.77 %, P = 0.055). In conclusion, during the use of basic oral care, endothelial function improved in patients without severe PPD, while it worsened in patients with severe PPD.

Review
OBJECTIVE
This study investigated the effect of photodynamic therapy on chronic periodontitis patients and then evaluated the microbial, immunological, periodontal, and clinical outcomes. The significant effects of photodynamic therapy obtained by and studies have made it a popular treatment for periodontal diseases in recent years. Photodynamic therapy is a novel bactericidal strategy that is stronger, faster, and less expensive than scaling and root planing.
METHOD
This study registered on PROSPERO (CRD42021267008) and retrieved fifty-three randomized controlled trials by searching nine databases (Medline, Embase, Scopus, Open Gray, Google Scholar, ProQuest, the Cochrane Library, Web of Science, and ClinicalTrials.gov) from 2008 to 2023. Of 721 records identified through database searches following title and full-text analysis, and excluding duplicate and irrelevant publications, 53 articles were included in this systematic review. Fifty of the 53 eligible studies fulfilled all the criteria in the Joanna Briggs Institute's (JBI's) Checklist for RCTs; the remaining articles met 9-12 criteria and were considered high quality.
RESULTS
The present study showed that photodynamic therapy in adjunct to scaling and root planing has the potential to improve periodontal parameters such as clinical attachment loss or gain, decrease in bleeding on probing, and probing pocket depth. In addition, photodynamic therapy decreases the rate of periodontal pathogens and inflammation markers, which, in turn, reduces the progression of periodontitis.
CONCLUSION
Photodynamic therapy is considered a promising, adjunctive, and low-cost therapeutic method that is effective in tissue repair, reducing chronic periodontitis, reducing inflammation, and well-tolerated by patients.

Periodontitis is an infection-driven inflammatory condition of the periodontium. Neutrophils are one of the most important first-line immune cells that protect against pathogen microorganisms in the saliva, but they may also mediate tissue death in inflammatory disorders. The aim of our study was to estimate salivary levels of azurocidin and extracellular azurophilic granules cluster of differentiation (CD63) as biomarkers of neutrophil activation in patients with periodontal diseases and to study the correlation between the levels of these two biomarkers and clinical periodontal parameters. The study included 60 patients with periodontal disease (30 patients with periodontitis and 30 with gingivitis) and 25 healthy controls. The assessed parameters were bleeding on probing, the plaque index, clinical attachment loss, and probing pocket depth. Saliva samples were taken from each study participant, and azurocidin and CD63 levels were measured using ELISA. Azurocidin and CD63 levels were significantly higher in patients with periodontitis and patients with gingivitis than in controls ( < 0.05), and significantly higher in patients with periodontitis than in patients with gingivitis ( < 0.05). Moreover, we found a significant positive correlation between the two biomarkers with clinical attachment loss in the periodontitis group. This study has shown that increased salivary azurocidin and extracellular CD63 levels are associated with enhanced innate response in periodontal disease and can be considered biomarkers of neutrophil activation.

Numerous studies have established a link between gene variants within the inflammasome complex and the incidence of periodontitis and cardiovascular illness across various ethnic groups. This study investigated the association between gene polymorphism and susceptibility to periodontal disease and coronary heart disease (CHD) and their correlation with clinical periodontal indices. A total of 120 participants were enrolled, categorized into four groups: 30 healthy controls (C), 30 patients with generalized periodontitis (P), 30 patients with atherosclerotic CHD but clinically healthy periodontium (AS-C), and 30 patients with both atherosclerotic CHD and generalized periodontitis (AS-P). We recorded demographic data, collected blood samples, and measured periodontal indices, including plaque index, clinical attachment loss, bleeding on probing, and pocket depth. The genomic variant of the gene was analyzed using a conventional polymerase reaction. A significant prevalence of T and G allele mutations and a higher distribution of CT and TT genotypes in C/T (rs8056505) and the AG genotype in A/G (rs372507365) were observed in groups P, AS-P, and AS-C. These single nucleotide polymorphisms (SNPs) were also positively correlated with the severity of clinical periodontitis indices. Our findings suggest that the increased frequency of T and G alleles and the distribution of CT, TT, and AG genotypes in SNPs are significantly associated with an elevated risk for periodontal disease and CHD. These SNPs may participate in the pathogenesis of these conditions. The study reinforces the potential role of these genetic markers as risk factors for both diseases in the Iraqi population.

Randomized Controlled Trial
Adjunctive use of laser biostimulation with nonsurgical periodontal therapy: a split-mouth, randomized, case-control study in diabetic and nondiabetic periodontitis patients.
BACKGROUND/AIM
Laser biostimulation therapy (LBT) is suggested to have positive effects on periodontal healing. This study evaluated LBT with nonsurgical periodontal therapy (NSPT) in diabetes mellitus (DM) and systemic health (SH) conditions.
MATERIALS AND METHODS
Thirty periodontitis patients (15 with DM and 15 with SH) were included in the study, which had a split-mouth design, by applying LBT in the mouth of the same systemic condition. Thus, 4 study groups were formed, as 1) NSPT - DM: NSPT alone in DM, 2) NSPT + LBT - DM: NSPT + LBT application in DM, 3) NSPT - SH: NSPT alone in SH, and 4) NSPT + LBT - SH: NSPT + LBT application in SH. NSPT was performed on days 15, 30, 37, 44, 51, 58, and 65. LBT was performed 6 times on days 30, 37, 44, 51, 58, and 65 with an Nd:YAG laser. The plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing pocket depth (PPD), and clinical attachment level (CAL) were assessed as the clinical parameters and recorded at baseline and days 30, 37, and 72. Gingival crevicular fluid levels of interleukin 1 beta (IL-1β) and IL-10 were evaluated by ELISA as the biochemical parameters at baseline and on days 30, 37, and 72.
RESULTS
Clinical parameters had improved in all of the groups on day 72 (p < 0.01). PPD and CAL improved more in the DM group with NSPT and LBT group than in the DM group with NSPT without LBT on day 37 (p < 0.05). IL-1β decreased and IL-10 increased in all of the groups on day 72 (p < 0.01). This change was more evident in the DM group with NSPT and LBT than in the DM group with NSPT without LBT on day 7 (p < 0.05).
CONCLUSION
These results revealed the short-term impacts of LBT on periodontal healing, which return to ineffectiveness with repeated irradiation. Therefore, it may be speculated that LBT via the protocol herein may have a short-term antiinflammatory contribution to NSPT, only in impaired healing conditions such as DM.

Randomized Controlled Trial
BACKGROUND/AIM
Scaling and root planing remain inadequate in periodontitis treatment caused by dysbiotic microbial dental plaque. The aim of this clinical trial is to evaluate the effects of probiotics and kefir consumption in initial periodontal therapy (IPT) on oral microbiota composition and treatment outcomes in patients with periodontitis.
MATERIALS AND METHODS
The study was carried out in the Gazi University Department of Periodontology, including a sample size of 36 individuals and utilizing a randomized controlled design. Thirty-six patients with periodontitis were randomly allocated to three groups: one receiving probiotic treatment, another receiving kefir, and a third serving as the control group. Obtaining subgingival microbial samples, we recorded plaque, gingival index, bleeding on probing, periodontal pocket depth, and clinical attachment level (periodontal clinical indices) and then performed IPT. For 14 days, patients took either probiotics, kefir, or no supplements. Data for the first and third months were collected using periodontal clinical indices. DNA sequencing was performed to detect , , and in subgingival plaque samples collected at baseline and three months.
RESULTS
Significant differences were observed regarding periodontal clinical indices among groups in the intragroup comparisons. Moreover, levels of were significantly decreased in all groups.
CONCLUSION
Kefir can be administered in addition to IPT, providing results similar to those observed with probiotics.

The study aimed to evaluate the periodontal disease status in different age groups and clarify the relationship between aging and the severity of periodontal disease. The test animals were cynomolgus monkeys that were born and raised at the Tsukuba Primate Research Center of the National Institutes of Biomedical Innovation, Health, and Nutrition. The participants were divided into three groups: young (5-10 years old), middle (10-19 years old), and old (≥20 years old). The plaque Index (PLI), Gingival Index (GI), probing pocket depth (PPD), and Bleeding on probing (BOP) were used for the periodontal examination. Representative teeth were also examined. Polymerase chain reaction (PCR) was used to identify Porphyromonas macacae in dental plaque. Multiple comparisons and regression analyses were used to analyze the relationship between each age group and each oral examination index. Statistically significant differences were found between the age groups and periodontal examination index. Multiple regression analysis revealed that age was strongly correlated with each oral examination index. Based on these results, oral examinations of cynomolgus monkeys kept in the same environment confirmed an association between aging and periodontal disease severity. Monkeys at this facility are expected to serve as new experimental models for elucidating the mechanisms underlying the progression of age-related periodontal disease.
