Association between raftlin and presepsin levels with periodontal healthy and disease conditions.

OBJECTIVE: The aim of this study was to examine the association between Raftlin and Presepsin levels in periodontal healthy/diseases, hypothesizing a change in their levels. Also, the study aimed to determine their potential role in diagnosing and predicting the prognosis of periodontal diseases. DESIGN: A cross-sectional study design was used, including 20 periodontally healthy individuals, 21 gingivitis patients, and 21 periodontitis patients. Clinical measurements and gingival crevicular fluid (GCF) sample collection were conducted, and the levels of Raftlin and Presepsin were analyzed. Statistical analysis was performed to evaluate the differences and correlations among the groups. RESULTS: Raftlin and Presepsin levels displayed significant variations among groups in both total amount (mean values for Raftlin in periodontitis, gingivitis, and healthy were 33.42, 17.45, 7.70 pg/30 s, respectively; for Presepsin, values were 3.98, 3.01, 1.92 pg/30 s, respectively) (p < 0.001) and concentration levels (pg/µl) (p = 0.007 for Raftlin, p = 0.026 for Presepsin). Particularly noteworthy were the concentration distinctions observed exclusively between the periodontitis and healthy groups. CONCLUSIONS: The present study offers preliminary insights into the presence and variations of raftlin and prepsepsin in the GCF across different periodontal conditions. While these findings hint at a potential role for these markers in periodontal disease, further research is essential to fully understand their diagnostic and prognostic capabilities.

Preventive effects of Capparis Spinose extract on experimental periodontitis in rats: a histopathological and biochemical study.

This study aimed to assess the effectiveness of Capparis Spinose (CS) in preventing the initiation and progression of experimental periodontitis and to evaluate the effect of its on systemic oxidative stress in rats by experimental periodontitis model. Twenty-four male rats were equally divided into; Ligatured (L), non-ligatured (NL), and Ligatured with CS (11 days/day per 20 mg/kg) (LC) groups. Experimental periodontitis was induced with the silk suture technic. Alveolar bone loss was examined, and total antioxidant capacity(TAOC), total oxidant status(TOS), and oxidative stress index(OSI) were analyzed in rat serum. Although; alveolar bone loss showed statistically significant lower values in the LC group compared to L (p < 0.05), not NL. In the LC group, osteoclast and osteoblast numbers were statistically significant compared to L, but there were no statistical differences between LC and NL. Serum TAOC levels were significantly lower in group L compared to others and also LC group showed significant differences from NL. TOS and OSI levels were significantly higher in group L than in other groups. Within the limitation of the present study, it can be said that the destruction via local inflammation that may occur after the experimental periodontitis can be prevented by using CS.

Effect of peri-implant disease on oral health-related quality of life in geriatric patients.

OBJECTIVE: This study aimed to evaluate the effect of peri-implant disease on the quality of life in geriatric patients using implant-supported overdentures. BACKGROUND: Peri-implant disease and bone loss are two main complications of dental implant treatment that can impact the quality of life in the geriatric population. MATERIALS AND METHODS: This cross-sectional study included 109 geriatric individuals treated in the prosthodontics and periodontology departments. On clinical examination, periodontal pocket depth, gingival index (GI) and plaque index (PIn) were measured to determine peri-implant status. Marginal bone loss was measured by radiological examination, using ImageJ software. Moreover, the Oral Healthy Impact Profile-14 (OHIP-14) questionnaire was used to evaluate participants' perceived oral health-related quality of life. RESULTS: Peri-implantitis (PI) and peri-implant mucositis (PM) prevalence were 30% and 24%, respectively. Only 44% of patients had healthy implants. Although total OHIP-14 scores were higher in the PI group than in the healthy and PM groups, this difference was not statistically significant (P = .148). Total OHIP-14 score was significantly correlated with PIn and GI. CONCLUSIONS: Within the limitations of this study, it can be said that on quality of life in patients using implant-supported overdenture related to clinical parameters such as PIn and GI. Results also indicated that geriatric patients should take action to improve their oral health. Further longitudinal studies are needed to support our results and should include control groups that use conventional removable dentures.

The Effect of Periodontal and Peri-Implanter Health on IL-1 and TNF- Levels in Gingival Crevicular and Peri-Implanter Sulcus Fluid: a Cross-Sectional Study / El efecto de la salud periodontal y peri-implantar en niveles de IL-1ß y TNF-α en el fluido crevicular y sulcus peri-implantador: un estudio transversal

Abstract: It is stated that peri-implanter diseases have destructive effects similar to periodontal diseases. This study aims to compare IL-1β and TNF-α levels in healthy and diseased areas. Forty non-smokers systemically health individuals (40 implants/40 teeth) (age:38-67) were included in the study. In clinical and radiographic examinations; plaque index (PIn), gingival index (GI), periodontal pocket depth (PPD), clinical attachment level (CAL) and marginal bone loss (MBL) values were recorded. The gingival crevicular fluid (GCF) and peri-implanter sulcus fluids (PISF) of the patients were collected, and IL-1β and TNF-α levels were measured by ELISA in the samples. The collected data were analyzed with the help of SPSS v.22 package program. Sample PPD score showed a statistically significant difference between the diseased and healthy groups and also sample CAL showed statistically significant higher in Periodontitis(P) compared to periodontally heathy(H) and Gingivitis(G) (p>0.05). IL-1beta and TNF-α levels in GCF/PISF; In the P and Peri-implantitis (PI) group, it was found statistically significantly higher than the H, Healthy-Implant (HI), besides P showed higher levels compared to G (p<0.05). Within the limitations of our study, it can be said that IL-1β and TNF-α among inflammatory cytokines in GCF/PISF will increase in periodontal and peri-implanter diseases, it can also be said that this increase in cytokines may indicate that periodontal and peri-implanter diseases have similar immunological structure. Peri-implant mucositis without periodontitis history has similarity to peri-implantitis and periodontitis in terms of IL-1β and TNF-α levels in GCF/PISF.

Resumen: Se afirma que las enfermedades peri-implantarias tienen efectos destructivos similares a los de las enfermedades periodontales. Este estudio tiene como objetivo comparar los niveles de IL-1β y TNF-α en zonas sanas y enfermas. Cuarenta individuos no fumadores con salud sistémica (40 implantes/40 dientes) (edad:38-67) fueron incluidos en el estudio. En los exámenes clínicos y radiográficos se registraron los valores de índice de placa (PIn), índice gingival (GI), profundidad de la bolsa periodontal (PPD), nivel de fijación clínica (CAL) y pérdida de hueso marginal (MBL). Se recogieron los fluidos creviculares gingivales (GCF) y los fluidos del surco peri-implantario (PISF) de los pacientes, y se midieron los niveles de IL-1β y TNF-α mediante ELISA en las muestras. Los datos recogidos fueron analizados con la ayuda del programa de paquete SPSS v.22. La puntuación PPD de la muestra mostró una diferencia estadísticamente significativa entre los grupos enfermos y sanos y también la muestra CAL mostró estadísticamente significativa más alta en la Periodontitis (P) en comparación con la salud periodontal (H) y la Gingivitis (G) (p>0.05). Los niveles de IL-1beta y TNF-α en GCF/PISF. En el grupo de P y Peri-implantitis (PI), se encontró estadísticamente significativo más alto que el H, implante sano (HI), además P mostró niveles más altos en comparación con G (p<0.05). Dentro de las limitaciones de nuestro estudio, se puede decir que IL-1β y TNF-α entre las citoquinas inflamatorias en GCF/PISF aumentarán en las enfermedades periodontales y peri-implantarias. También se puede decir que este aumento de citoquinas puede indicar que las enfermedades periodontales y peri-implantarias tienen una estructura inmunológica similar. La mucositis peri-implantaria sin antecedentes de periodontitis tiene similitudes con la peri-implantitis y la periodontitis en cuanto a los niveles de IL-1β y TNF-α en la GCF/PISF.

Photobiomodulation Therapy by 820 nm Diode Laser on Nonsurgical Periodontal Treatment of Smoker and Nonsmoker Patients: A Single-Blind Parallel Randomized Clinical Trial.

The effect of smoking on nonsurgical periodontal treatment (SRP) is known, but the adjunct use of photobiomodulation (PBMT) to SRP has not been fully investigated in smokers. This study aimed to assess the effect of 820 nm diode laser on SRP in smoker/nonsmoker. Sixty patients (smokers/n = 30, nonsmokers/n = 30) were enrolled in this parallel-arm clinical study. All patients were divided into two main groups: SRP and PBMT + SRP. In PMBT + SRP groups, 7.96 J cm-2 energy was applied by 820nm diode laser at baseline and first, second and third weeks after SRP. Periodontal pocket depth (PPD), gingival index (GI), plaque index (PI) and clinical attachment level (CAL) were recorded, and also gingival crevicular fluid (GCF) samples were collected at baseline and 6w after SRP. Total antioxidant capacity (TAOC) and total oxidative status (TOS) in GCF were analyzed. PBMT + SRP groups showed a statistically significant decrease in PPD and CAL, not in GI and PI compared with SRP alone. There were no statistically significant differences between smokers and nonsmokers in clinical data at six weeks after treatment. Although TAOC levels were increased in PMBT groups, TOS levels were decreased in all groups at the comparison of baseline and 6w after SRP. Adjunct use of 820 nm diode laser on SRP may improve the clinical parameters in smoker or nonsmoker patient with periodontitis.

Gingival crevicular fluid levels of cytokine, chemokine, and growth factors in patients with periodontitis or gingivitis and periodontally healthy subjects: a cross-sectional multiplex study.

INTRODUCTION: Gingival crevicular fluid (GCF) is an important resource for detecting inflammatory biomarkers related to periodontal disease. The purpose of this research was to identify the possible relation between cytokine levels and periodontal status. MATERIAL AND METHODS: GCF samples collected from 25 periodontally healthy individuals, 24 with gingivitis, and 24 with periodontitis were analyzed using the MAGPIX system with a Bio-Plex Pro Human Cytokine 27-plex kit. Gingival index (GI), periodontal pocket depth (PPD), plaque index (PI), and clinical attachment level (CAL) were measured from each tooth to determine each patient's periodontal status. RESULTS: All clinical parameters showed statistically significant differences between groups. While interleukin (IL)-1ß, IL-6, macrophage chemotactic protein 1 (MCP-1), interferon γ-induced protein 10 (IP-10) and vascular endothelial growth factor (VEGF) levels were statistically significantly higher in patients with periodontitis compared to periodontally healthy subjects, IL-15 levels were found to be statistically significantly higher in periodontally healthy individuals compared to periodontitis (p < 0.05). Also, IL-1ß and IP-10 showed positive correlations with PPD, CAL, GI and bleeding on probing (BOP). CONCLUSIONS: It is considered that IL-1ß, IL-6, IL-15, MCP-1, VEGF and IP-10 could be related to periodontal disease and health and can be used as an adjunct to clinical examination in future research design. Scanning cytokines in GCF with a multiplex immunoassay technique is consequential, especially because many cytokine types are found in one sample.

The effect of photobiomodulation therapy on nonsurgical periodontal treatment in patients with type 2 diabetes mellitus: a randomized controlled, single-blind, split-mouth clinical trial.

Photobiomodulation therapy (PBMT) is a method currently used in the treatment of hard and soft tissue injuries due to its accelerating and enhancing effects on healing. In this study, we aimed to evaluate the possible additional benefits of applying PBMT with nonsurgical periodontal treatment in type 2 diabetes mellitus (DM) patients with chronic periodontitis (CP). Twenty-two type 2 DM patients with CP were enrolled in this clinical split-mouth study. Probing pocket depth (PPD), gingival index (GI), plaque index (PI), and clinical attachment level (CAL) were measured by intracaliber clinician (H.G.) at baseline and at 1 m, 3 m, and 6 m after treatment. Gingival crevicular fluid (GCF) samples were collected at baseline and at 1 week and 1 m, 3 m, and 6 m after treatment. According to split-mouth design, one randomly selected quadrant was treated with PBMT + nonsurgical periodontal treatment (NSPT) and the other quadrant was treated only non-surgical periodontal treatment. PBMT was applied the test quadrant on NSPT day and first, third, and seventh day after treatment at an energy density of 7.64 J/cm2. Repeated measures analysis of variance test was used for the intragroup comparison and a "paired t test" in the intergroup comparison of the clinical and laboratory findings. Comparing the test and control quadrant after treatment, the test quadrant showed significant decrease in PPD at 1 month, 3 months, and 6 months; in GI at 3 months and 6 months; in CAL at month 6; in GCF at 1 week, 1 month, 3 months, and 6 months; and in IL-1ß data at 3 months in comparison to the control quadrant. In contrast, there was no statistically significant difference in PI data at all times. Within the limitation of this study, adjunct use of PBMT on NSPT in patient with DM may positively affect the clinical and biochemical parameters.

Adjunct Use of Low-Level Laser Therapy on the Treatment of Necrotizing Ulcerative Gingivitis: A Case Report.

Necrotizing ulcerative gingivitis (NUG) is a microbial disease of the gingiva in the context of an impaired host response. This form of gingivitis is relatively rare. NUG is an infection characterized by gingival necrosis presenting as "punched-out" papillae, spontaneous bleeding, pain, oral malodor, and pseudomembrane formation. The primary predisposing factors are bacterial plaque and an inadequate diet, but smoking and psychological stress may also affect the disease severity. NUG is associated with a characteristic bacterial flora, which includes fusiform bacteria, spirochetes, and Prevotella intermedia. Conventional treatment includes control of both the bacterial plaque and the secondary factors, as well as topical or systemic treatment biostimulative effect on wound healing, pain control, and inflammatory processes. Patients with NUG were treated using adjunct use of a diode laser (980 nm) for the control of pain and to accelerate the wound healing at day 2. 3. 5. 9, energy density was 9 J/cm2 . After treatment, the patients' quality of life improved faster than with conventional treatment. These results suggest that low-level laser therapy (LLLT) is an effective treatment for the reduction of pain levels and healing times. As a result, our case report shows that LLTT has a positive effect in relieving the symptoms of NUG.

Water pipe (Shisha, Hookah, Arghile) Smoking and Secondhand Tobacco Smoke Effects on CYP1A2 and CYP2A6 Phenotypes as Measured by Caffeine Urine Test.

Public policies to stop or reduce cigarette smoking and exposure to secondhand smoke and associated diseases have yielded successful results over the past decade. Yet, the growing worldwide popularity of another form of tobacco consumption, water pipe smoking, has received relatively less attention. To the best of our knowledge, no study to date has evaluated the effects of water pipe smoking on cytochrome P450 (CYP450) activities and drug interaction potential in humans, whereas only limited information is available on the impact of secondhand smoke on drug metabolism. In a sample of 99 healthy volunteers (28 water pipe smokers, 30 secondhand tobacco smoke exposed persons, and 41 controls), we systematically compared CYP1A2 and CYP2A6 enzyme activities in vivo using caffeine urine test. The median self-reported duration of water pipe smoking was 7.5 h/week and 3 years of exposure in total. The secondhand smoke group had a median of 14 h of self-reported weekly exposure to tobacco smoke indoor where a minimum of five cigarettes were smoked/hour for a total of 3.5 years (median). Analysis of variance did not find a significant difference in CYP1A2 and CYP2A6 activities among the three study groups (p > 0.05). Nor was there a significant association between the extent of water pipe or secondhand smoke exposure and the CYP1A2 and CYP2A6 activities (p > 0.05). Further analysis in a subsample with smoke exposure more than the median values also did not reveal a significant difference from the controls. Although we do not rule out an appreciable possible impact of water pipe smoke and secondhand smoke on in vivo activities of these two drug metabolism pathways, variability in smoke constituents from different tobacco consumption methods (e.g., water pipe) might affect drug metabolism in ways that might differ from that of cigarette smoke. Further studies in larger prospective samples are recommended to evaluate water pipe and secondhand tobacco smoke effects on CYP450 function, particularly at higher smoke exposure conditions.

The effect of low-level laser therapy on non-surgical periodontal treatment: a randomized controlled, single-blind, split-mouth clinical trial.

The purpose of this split-mouth, single-blind, controlled clinical study was to evaluate the impact of low-level laser therapy (LLLT) as an adjunct to non-surgical treatment of chronic periodontitis. Twenty-five systemically healthy and non-smoking adults with chronic periodontitis who had at least two bilateral premolar teeth with probing pocket depth (PPD) of 7 ≥ x ≥ 5 mm were included in the study. In the periodontal examination of these patients, PPD, gingival index (GI), plaque index (PI), clinical attachment level (CAL), and bleeding on probing (BOP) were recorded at the baseline, first, third, and sixth months after treatment. Gingival crevicular fluid (GCF) samples were taken at the baseline, first week, and first month after treatment. The collected GCF samples were analyzed using the MAGPIX™ system with a Bio-Plex Pro™ Human Cytokine 27-plex kit. After non-surgical periodontal treatment, LLLT with an energy density of 7.64 J/cm2 was performed four times: immediately after scaling and root planning (SRP) and on the first, third, and seventh day after treatment. In the first month, PPD levels were significantly (p < 0.05) lower in the SRP + LLLT group than in the SRP group. At the third and sixth months, CAL, PPD, and GI were significantly (p < 0.05) lower in the SRP + LLLT group than in the SRP group. Differences in GCF cytokines levels among the group were not statistically significant. Within the limitations of this study, it is indicated that LLLT as an adjunct to non-surgical periodontal treatment has a positive impact on clinical parameters.

Effect of Chronic Periodontitis on Oxidative Status in Patients With Psoriasis and Psoriatic Arthritis.

BACKGROUND: Psoriasis (PS), psoriatic arthritis (PsA), and chronic periodontitis (CP) are the most common chronic inflammatory diseases and have remarkable pathologic similarities. The aim of this study is to investigate the effect of periodontal inflammation on oxidative stress in patients with PS and PsA by evaluating serum total antioxidant status, total oxidant status, oxidative stress index, levels of lipid hydroperoxides, and the activities of paraoxonase, arylesterase, and ceruloplasmin. Also measured were the levels of prolidase and total sulfhydryl groups. METHODS: A total of 120 participants were divided into six groups of 20 participants: 1) PS with CP (PS-CP); 2) PS-periodontally healthy (PS-C); 3) PsA with CP (PsA-CP); 4) PsA-periodontally healthy (PsA-C); 5) systemically healthy with CP (CP); and 6) both systemically and periodontally healthy (C). Demographic, periodontal, and serum oxidative parameters were evaluated. RESULTS: Oxidative stress index values of PS-C, PS-CP, PsA-C, and PsA-CP groups were approximately twice as high as those of C and CP groups, and there were no differences between any of the PS (PS-C and PS-CP), and PsA (PsA-C and PsA-CP) groups. Total antioxidant status levels of the C group were higher by 27% compared with those of the PS-C and the PsA-CP groups (P <0.05). Total oxidant status levels of both PsA-C and PsA-CP groups were approximately twice as high as those of the C (P <0.05) and CP (P <0.05, P <0.001 respectively) groups. CONCLUSIONS: The contribution of CP on systemic oxidative levels in patients with PS and PsA or systemically healthy individuals seems limited. PS and PsA did not show any additional detrimental effect on clinical parameters in patients with CP.

Clinical and biochemical effects of 810 nm diode laser as an adjunct to periodontal therapy: a randomized split-mouth clinical trial.

OBJECTIVE: The aim of this clinical trial was to determine the clinical and biochemical efficacy of an 810 nm diode laser as an adjunct to scaling and root planing (SRP). BACKGROUND DATA: Lasers can achieve excellent tissue ablation with strong bactericidal and detoxification effects. The use of lasers is one of the most promising new technical modalities for nonsurgical periodontal treatment. However, the most effective wavelength and parameters for their use are still under investigation. METHODS: This study was designed as a single-blinded, randomized-controlled, split-mouth clinical trial. Twenty-one patients (12 females and 9 males between 26 and 55 years of age), diagnosed with generalized chronic periodontitis, were included in the study. After initial periodontal therapy, which consisted of oral hygiene instructions and scaling, patients underwent two different treatment modalities. Test and control sites were chosen with coin toss randomization. At the test site, patients received SRP and laser treatment; at the contralateral control site, they received SRP treatment alone. RESULTS: Both treatment modalities resulted in significant improvements in all clinical and biochemical parameters. Sites irradiated with an 810 nm diode laser using the "hot tip" (∼ 760 °C) technique showed enhanced healing in all the registered periodontal variables and interleukin (IL)-1ß levels, compared with SRP alone. CONCLUSIONS: Within the limitations of this study, the use of diode lasers as an adjunct to SRP produced significant improvements in clinical parameters as well as gingival crevicular fluid (GCF) IL-1ß levels in the 6 month study period.

Host modulation in rheumatoid arthritis patients with TNF blockers significantly decreases biochemical parameters in periodontitis.

The aim of this study was to evaluate the effects of host modulation therapy on periodontal and biochemical parameters. Sixteen rheumatoid arthritis patients newly scheduled for anti-tumour necrosis factor (TNF) therapy were screened for 30 days. Periodontal parameters (clinical attachment level, probing pocket depth, bleeding on probing, plaque index and gingival index) as well as salivary and gingival crevicular fluid (GCF), interleukin (IL)-1ß, IL-8 and monocyte chemoattractant protein-1 (MCP-1) levels of the patients were evaluated at baseline and on the 30th day of therapy. GCF volume, IL-1ß and IL-8 levels (p = 0.007, p = 0.017 and p = 0.009, respectively) of the periodontitis patients significantly decreased. Although there was a decrease in all these parameters in healthy patients, it was below statistical significance. Salivary IL-8 and MCP-1 levels significantly decreased in periodontitis patients (p = 0.028 and p = 0.013, respectively), but IL-1ß levels remained unchanged. These results suggest that TNF blockers may significantly modify host response in terms of biochemical parameters of the periodontium and may mask significant associations such as those reported between periodontitis and rheumatoid arthritis.
