Savran L, Sağlam M. Clinical effects of omega-3 fatty acids supplementation in the periodontal treatment of smokers and non-smokers with periodontitis: a retrospective study. Clin Oral Investig 2024; 28:437. [PMID: 39031219 PMCID: PMC11271343 DOI: 10.1007/s00784-024-05835-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 07/17/2024] [Indexed: 07/22/2024]
Abstract
OBJECTIVES Omega-3 supplementation as an adjunct to nonsurgical periodontal treatment has been reported to have a positive effect on healing in periodontitis patients. However, there is a lack of information on the effects of periodontal healing in smokers with periodontitis. The aim of this retrospective study was to investigate the effect of omega-3 supplementation given as an adjunct to nonsurgical periodontal treatment on clinical parameters in smoker and non-smoker periodontitis patients. METHODS This study included a total of 80 periodontitis patients, 40 non-smokers and 40 smokers who were systemically healthy. In this study, patients were divided into 4 groups as follows: Group 1 (Subgingival instrumentation (SI) alone/nonsmoker), Group 2 (SI alone/smoker), Group 3 (SI + Omega-3/nonsmoker) and Group 4 (SI + Omega-3/smoker). Group 3 and 4 consumed 1320 mg Omega-3 capsule (640 mg EPA, 480 mg DHA) once a day for 3 months. Probing depth (PD), clinical attachment level (CAL), gingival index (GI), plaque index (PI) and bleeding on probing (BOP %) were recorded at baseline, 1 month and 3 months after treatment. RESULTS Significant improvement of all clinical parameters at 1 and 3 months was observed in all groups. Whole mouth CAL, GI and BOP% were significantly reduced in group 4 compared to group 2 at 1 and 3 months postoperatively (p < 0.05). For moderately deep pockets (4-6 mm) and deep pockets (7 mm≤), PD and CAL reductions were significantly greater in groups taking omega - 3 (group 3 and group 4) compared to groups not taking omega-3 (group 1 and group 2) between baseline and 1 month and between baseline and 3 months (p ˂ 0.05). CONCLUSION Omega-3 supplementation given as an adjunct to nonsurgical periodontal treatment provided significant benefit in the improvement of clinical parameters (especially for CAL and PD) in the short term in smokers and non-smokers with periodontitis. CLINICAL RELEVANCE Nonsurgical periodontal treatment with omega-3 supplementation resulted in significant improvements in clinical parameters in smokers and non-smokers with periodontitis.

Abstract
Background Subgingival bacterial colonization and biofilm formation are known to be the main etiology of periodontal disease progression. This biofilm elicits host response and the interaction between host defence mechanisms with plaque microorganisms and their products results in periodontal disease. Host modulatory therapy (HMT) is a form of treatment of periodontitis that focuses on treatment of the host in the host-bacteria interaction. Omega-3 fatty acids have emerged as a potential HMT agent to treat inflammation associated with periodontal disease. Methods A total of 60 cases of chronic periodontitis were allocated into two groups; the test group (n = 30) were treated with scaling and root planing (SRP) and given a dietary supplementation of omega-3 fatty acid while the control group were treated with SRP alone. Clinical parameters carried out were plaque index (PI), gingival bleeding index (GBI), pocket probing depth (PPD) and clinical attachment level (CAL) and immunological parameter included interleukin-1β level in saliva at baseline, 3 months and 6 months after therapy. Results At 6 months, both the groups showed significant improvements with regards to all clinical and immunological parameters compared to baseline (all p < 0.05). However, test group presented with more favourable statistically significant results. Conclusion The use of omega-3 fatty acid as nutraceutical agent to conventional method acted as beneficial therapeutic measures and effective in patients with chronic periodontitis when compared with SRP alone.

Abstract
Periodontitis is an oral-cavity inflammatory disease and is the principal cause associated with tooth loss. Matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9) are important proteases involved in periodontal tissue destruction. The omega-3 polyunsaturated fatty acids (ω-3 PUFA) have been demonstrated to possess immunoregulatory properties in periodontitis. The aim of the study was to investigate the effects of ω-3 PUFA on inflammation and on the expression of MMP-2 and -9 in a murine periodontitis model. Twenty-four male C57BL/6 mice were divided into control mice (Control), control mice treated with ω-3 PUFA (O3), mice with periodontitis (P), and mice with periodontitis treated with ω-3 PUFA (P + O3). ω-3 PUFA were administered orally once a day for 70 days. Periodontitis in mice was induced by Porphyromonas gingivalis-infected ligature placement around the second maxillary molar. The mice were sacrificed, and blood and maxillary samples were collected. Flow cytometry was used to quantify tumor necrosis factor-alpha (TNFα), interleukin (IL)-2, IL-4, IL-5, and interferon-gamma. Histologic analysis and immunohistochemistry for MMP-2 and -9 were performed. The data were statistically evaluated using analysis of variance (ANOVA) and the Tukey post hoc test. Histological analysis showed that ω-3 PUFA supplementation prevented inflammation and tissue destruction and revealed that bone destruction was more extensive in the P group than in the P + O3 group (p < 0.05). Also, it decreased the serum expressions of TNFα and IL-2 and the tissue expression of MMP-2 and -9 in the periodontitis-induced model (p < 0.05). ω-3 PUFA supplementation prevented alveolar bone loss and periodontal destruction, probably by decreasing the expression of MMP-2 and MMP-9 and its immunoregulatory properties.

Abstract
Periodontitis is one of the most common dental diseases with a range of treatment approaches, including pathogenetically reasonable use of various host immune modulators. One such approach is the use of omega-3 polyunsaturated fatty acids (PUFAs) in combination with low-dose aspirin. This systematic review and meta-analysis were performed to compare the standard treatment alone and adjunctive use of omega-3 PUFAs in combination with low-dose aspirin with or without standard treatment in patients with periodontitis. A systematic review of the literature was performed using MEDLINE/PubMed, Cochrane Central and Google Scholar databases. Selection criteria included the following: randomized controlled trials in subjects with periodontitis in the age group above 18 years old, with follow-up periods ranging from 6 weeks to 6 months. The meta-analysis was performed using standard methodological procedures according to Cochrane recommendations, including assessment of risk-of-bias and level of evidence (GRADE). Meta-analysis was performed for such clinical outcomes as plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment loss (CAL), bleeding on probing (BOP) and bleeding index (BI) based on data from seven randomized clinical trials conducted between 2010 and 2020. It was shown that adjunctive use of omega-3 PUFAs in combination with low-dose aspirin results in significant clinical improvement in PD, CAL and GI during both short and prolonged follow-up periods. The use of omega-3 PUFAs and low-dose aspirin in periodontitis patients may be promising as an adjunct therapy, however, due to a limited number of patients and significant heterogeneity, further studies need to be conducted.

Abstract
Periodontal disease is an oral disorder with high prevalence in cats from 2 years of age, resulting from an inflammatory response against bacterial plaque. Treatment depends on the stage of the disease and may include dental scaling, local application of perioceutics, tissue regeneration and/or even tooth extraction and periodontal surgery. As multimodal therapy is often required, new strategies have been developed to improve the therapeutic response in these patients. Adjuvant use of omega-3 fatty acids has been reported in humans with periodontal disease, but the current evidence of its effect in companion animals, especially cats, is still considered to be scarce and conflicting. This review describes the state of the art regarding feline periodontal disease and seeks to clarify the potential effect of omega-3 fatty acids on its clinical management in light of the evidence available in the current literature.

Abstract
OBJECTIVE To determine whether Bifidobacterium animalis subspecies lactis HN019 (B. lactis HN019) can reduce the sequelae of experimental periodontitis (EP) in rats modulating systemic parameters. BACKGROUND This study evaluated the effects of probiotic therapy (PROB) in the prevention of local and systemic damage resulting from EP. METHODS Forty-eight rats were allocated into four groups: C (control), PROB, EP, and EP-PROB. PROB (1 × 1010 CFU/mL) administration lasted 8 weeks and PE was induced on the 7th week by placing ligature on the animals' lower first molars. All animals were euthanized in the 9th week of the experiment. Biomolecular analyses, RT-PCR, and histomorphometric analyses were performed. The data obtained were analyzed statistically (ANOVA, Tukey, p < .05). RESULTS The EP group had higher dyslipidemia when compared to the C group, as well as higher levels of insulin resistance, proteinuria levels, percentages of systolic blood pressure, percentage of fatty hepatocytes in the liver, and expression of adipokines was up-regulated (LEPR, NAMPT, and FABP4). All these parameters (except insulin resistance, systolic blood pressure, LEPR and FABP4 gene expression) were reduced in the EP-PROB group when compared to the EP group. The EP group had lower villus height and crypt depth, as well as a greater reduction in Bacteroidetes and a greater increase in Firmicutes when compared to the EP-PROB group. Greater alveolar bone loss was observed in the EP group when compared to the EP-PROB group. CONCLUSION Bifidobacterium lactis HN019 can reduce the sequelae of EP in rats modulating intestinal parameters, attenuating expression of lipogenic genes and hepatic steatosis.

Abstract
Periodontal disease is an inflammatory and destructive disease of tissues supporting the tooth. A large number of studies have confirmed that periodontal pathogens and their metabolites can lead to adverse pregnancy outcomes in direct or indirect ways. Adverse pregnancy outcomes, such as preterm birth, low birth weight, and pre-eclampsia, have a serious impact on human reproductive health. In recent years, although the level of global medical technology has gradually improved, the incidence of adverse pregnancy outcomes has not declined and is still a global public health problem. The purpose of this review is to summarize the current data on periodontal disease in pregnancy and adverse pregnancy outcomes, including the association between periodontal disease and adverse pregnancy outcomes, the pathogenic mechanism related to this association, the efficacy of different nutrition supplements for both periodontal disease and adverse pregnancy outcomes and the effect of providing periodontal treatment on the occurrence of adverse pregnancy outcomes, to provide guidance for the prevention and treatment of adverse pregnancy outcomes in clinical practice.

Abstract
Background: This controlled clinical trial evaluated the impact of a specific collagen peptide food supplement on parameters of periodontal inflammation in aftercare patients. Methods: A total of 39 study patients were enrolled. At baseline, bleeding on probing (BoP; primary outcome), gingival index (GI), plaque control record (PCR), recession (REC) and probing pocket depth (PPD) for the calculation of the periodontal inflamed surface area (PISA) were documented. After subsequent professional mechanical plaque removal (PMPR), participants were randomly provided with a supply of sachets containing either a specific collagen peptide preparation (test group; n = 20) or a placebo (placebo group; n = 19) to be consumed dissolved in liquid once daily until reevaluation at day 90. Results: PMPR supplemented with the consumption of the specific collagen peptides resulted in a significantly lower mean percentage of persisting BoP-positive sites than PMPR plus placebo (test: 10.4% baseline vs. 3.0% reevaluation; placebo: 14.2% baseline vs. 9.4% reevaluation; effect size: 0.86). Mean PISA and GI values were also reduced compared to baseline, with a significant difference in favor of the test group (PISA test: 170.6 mm2 baseline vs. 53.7 mm2 reevaluation; PISA placebo: 229.4 mm2 baseline vs. 184.3 mm2 reevaluation; GI test: 0.5 baseline vs. 0.1 reevaluation; GI placebo: 0.4 baseline vs. 0.3 reevaluation). PCR was also significantly decreased in both experimental groups at revaluation, but the difference between the groups did not reach the level of significance. Conclusions: The supplementary intake of specific collagen peptides may further enhance the anti-inflammatory effect of PMPR in periodontal recall patients.

Abstract
AIM "Host modulatory therapy" (HMT) with ω-3 fatty acids aims at reducing inflammation. With HMT as an adjunct, a better result of periodontal therapy is expected. The aim of this systematic review and meta-analysis (MA) was to examine the additional effect of ω-3 fatty acids to non-surgical periodontal therapy (SRP) on the probing pocket depth (PPD) and the clinical attachment level (CAL). MATERIALS AND METHODS MEDLINE-PubMed and Cochrane-CENTRAL libraries were searched up to January 2021 for randomized controlled trials in patients with chronic periodontitis, treated with SRP/placebo as controls and SRP/ω-3 fatty acids as the test group. RESULTS The search identified 173 unique abstracts, and screening resulted in 10 eligible publications. Descriptive analysis showed a significant effect on the PPD and CAL in favour of the groups with ω-3 fatty acids in the majority of comparisons. MA revealed that adjunctive use of ω-3 fatty acids to SRP resulted in 0.39 mm more PPD reduction (95% CI: -0.58; -0.21) and 0.41 mm more CAL gain (95% CI: -0.63; -0.19) than SRP alone. CONCLUSIONS In patients with periodontitis, dietary supplementation with ω-3 fatty acids as an adjunct to SRP is more effective in reducing the PPD and improving the CAL than SRP alone. If SRP is indicated, the use of ω-3 fatty acids can be considered for a moderate extra added effect on PPD reduction and CAL gain. The strength of this recommendation is moderate.

Abstract
BACKGROUND Omega-6 and omega-3 polyunsaturated fatty acids (PUFAs) are precursors of pro- and anti-inflammatory lipid mediators. Serum PUFA levels could influence the severity of inflammatory oral diseases, such as gingivitis. OBJECTIVE The study analyzed serum PUFA levels in a six-week randomized controlled trial in individuals on the Mediterranean diet (MedD), associations with the intake of specific foods, and possible correlations with oral inflammatory parameters. METHODS Data from 37 study participants on either a MedD (MedDG; n = 18) or a "Western diet" in the control group (CG, n = 19) were analyzed. Dental examinations and serum analyses were performed at two time points, T1 (baseline) and T2 (week 6). Serum PUFA status, adherence to the MedD, and data from a Food Frequency Questionnaire were analyzed. RESULTS Within the MedDG omega-6 fatty acid levels decreased significantly. In the overall sample, the proportional decrease in sites with bleeding on probing correlated weakly to moderately with the decrease in total omega-6 fatty acid level (Spearman's ρ = 0.274) and the decrease in gingival index correlated moderately with the decrease in linoleic acid level (Spearman's ρ = 0.351). Meat and fast-food consumption correlated positively with levels of various omega-6 fatty acids, whereas nut, fish, and dairy product consumption correlated positively with omega-3 levels. CONCLUSION Adherence to a MedD was associated with a decrease in serum omega-6 levels, which positively affected the omega-6/omega-3 ratio. The MedD associated reduction in serum omega-6 levels may be a mechanism that favorably affects gingival inflammatory parameters.

Abstract
AIM This systematic review examined the additional effect of taking omega-3 supplements on periodontal therapy. METHODS The focused question was "What is the possible effect of omega-3 supplementation concomitant to non-surgical periodontal therapy on clinical periodontal parameters?" Databases Cochrane, Embase, Google Scholar, PubMed, and Web of Science (January-July 2021) were searched to identify appropriate studies. Randomized clinical trials (RCT) about non-surgical therapy with omega-3 supplementation, with at least 3 months of supplementation period were included. Cochrane risk of bias tool version 2 and Grading of Recommendations Assessment, Development, and Evaluation were used. RESULTS A total of 1556 studies were found, of which eight studies met the inclusion criteria. All eight studies evaluated periodontal probing depth and clinical attachment loss; plaque and gingival inflammation were evaluated in seven studies. High variety of omega-3 dosage, different study lengths, questionable results from periodontal therapy (including test and control groups), high risk of bias and moderate quality of evidence prevented a satisfactory conclusion regarding the benefits of omega-3 supplementation. The studies' high heterogeneity avoided meta-analysis. CONCLUSION Notwithstanding all limitations, the promising effects of omega-3 supplementation presented in two six-month studies encourage performing RCT with better-defined treatment protocols and greater methodological rigor.

Abstract
Specialized pro-resolving mediators (SPMs) are endogenous small molecules produced mainly from dietary omega-3 polyunsaturated fatty acids by both structural cells and cells of the active and innate immune systems. Specialized pro-resolving mediators have been shown to both limit acute inflammation and promote resolution and return to homeostasis following infection or injury. There is growing evidence that chronic immune disorders are characterized by deficiencies in resolution and SPMs have significant potential as novel therapeutics to prevent and treat chronic inflammation and immune system disorders. This review focuses on important breakthroughs in understanding how SPMs are produced by, and act on, cells of the adaptive immune system, specifically macrophages, B cells and T cells. We also highlight recent evidence demonstrating the potential of SPMs as novel therapeutic agents in topics including immunization, autoimmune disease and transplantation.
