RESUMEN
BACKGROUND: Numerous studies support a bidirectional association between rheumatoid arthritis (RA), a chronic autoimmune degenerative inflammatory joint disease, and periodontitis, a chronic inflammatory disease caused by the immune reaction to bacteria organized in biofilms. RA and periodontitis are both multifactorial chronic inflammatory diseases that share common modifiable and non-modifiable risk factors. There is no cure for RA; treatment is based on lifestyle modifications and a variety of medications: nonsteroidal anti-inflammatory drugs (NSAID), glucocorticoids, and disease-modifying antirheumatic drugs (DMARDs, e.g., conventional synthetic DMARDs [csDMARDs]; biological DMARDs [bDMARD] and targeted synthetic DMARDs). There are molecular pathways of inflammation that are common to both RA and periodontitis. Thus, there is a potential effect of RA treatments on periodontitis. This systematic review aims to assess the impact of antirheumatic agents on periodontal conditions of patients suffering from both RA and periodontitis. METHODS: PubMed/MEDLINE, Cochrane Library, and Embase online databases were systematically explored, and a manual search was performed to identify relevant studies published until January 2023. This review is registered in the PROSPERO database (CRD42023409006). RESULTS: A total of 2827 articles were identified, and 35 fulfilled the inclusion criteria. The included studies generally show a consensus that, at normal dosage, NSAID and corticosteroids have negligible impact on periodontium. Similarly, csDMARD alone or in combination with other csDMARD demonstrated no adverse effect on periodontium. Monotherapy with bDMARD had a positive effect on periodontal pocket depths and gingival inflammation in the longitudinal studies up to 6 months but showed negligible effect on the periodontium in interventional studies with a longer follow-up (9 months and 15.1 months). However, the combination of tumor necrosis factor (TNF)-α inhibitors + methotrexate (MTX) was associated with a rise in gingival inflammation. Due to the considerable heterogeneity of the study designs, a meta-analysis could not reasonably be performed. CONCLUSION: Within the limitations of the available studies, there is evidence to suggest that bDMARD monotherapy may improve the periodontal condition of RA patients with periodontal disease to a certain extent; the concomitant medication of TNF inhibitor + MTX could worsen gingival inflammation. More data are required to understand the impact of RA therapies on periodontal health.

Epidemiological studies have identified periodontitis as a contributing factor to cardiovascular risk. Periodontitis is a chronic inflammatory disease that affects the tissues supporting the teeth. Although the nature of the association between periodontitis and cardiovascular disease (CVD) remains to be defined, the low-grade systemic inflammation and chronic bacteremia associated with periodontitis appear to be involved in the development of atherosclerosis and associated cardiovascular pathologies. Periodontal treatment has been shown to improve cardiovascular health parameters. A bidirectional preventive approach, involving the management of both periodontitis and cardiovascular risk factors, could lead to a reduction in morbidity and mortality related to cardiovascular disease.
Title: La parodontite : un risque sous-estimé des maladies cardiovasculaires. Abstract: Les études épidémiologiques identifient la parodontite, maladie inflammatoire chronique des tissus de soutien des dents, comme un facteur contribuant au risque cardiovasculaire. Bien que la nature de l'association entre parodontite et maladies cardio-vasculaires (MCV) reste à définir (causalité ou corrélation), l'inflammation systémique de bas grade et les bactériémies chroniques qui sont associées aux parodontites apparaissent impliquées dans le développement de l'athérosclérose et des maladies cardio-vasculaires associées. Le traitement parodontal semble contribuer à l'amélioration des paramètres de la santé cardiovasculaire. Dès lors, une approche de prévention bidirectionnelle, impliquant à la fois la gestion de la parodontite et des facteurs de risque cardiovasculaire, pourrait permettre une réduction de la morbidité et de la mortalité liées aux MCV.

BACKGROUND: We assessed the performance and patient satisfaction of a new insulin patch pump, the A7+TouchCare (Medtrum), compared with the Omnipod system. METHODS: This multicenter, randomized, open-label, controlled study enrolled 100 adult patients with type 1 or type 2 diabetes mellitus (A1C ≥ 6.5% and ≤ 9.5%, i.e., 48 to 80 mmol/mol) who were assigned with the Omnipod or with the A7+TouchCare pump for 3 months. The primary study outcome was the glucose management indicator (GMI) calculated with continuous glucose monitoring (CGM). RESULTS: Premature withdrawals occurs respectively in 2 and 9 participants in the Omnipod and TouchCare groups. In the Per Protocol analysis, the difference in GMI between groups was 0.002% (95% confidence interval -0.251; 0.255). The non-inferiority was demonstrated since the difference between treatments did not overlap the pre-defined non-inferiority margin (0.4%). There was no significant difference in CGM parameters between groups. On average, patients in both groups were satisfied/very satisfied with the insulin pump system. Patients preferred Omnipod as an insulin management system and especially the patch delivery system but preferred the A7+TouchCare personal diabetes manager to control the system. CONCLUSIONS: This study showed that the A7+TouchCare insulin pump was as efficient as the Omnipod pump in terms of performance and satisfaction. CLINICAL TRAIL REGISTRATION: The study was registered in the ClinicalTrials.gov protocol register (NCT04223973).

This systematic review aimed to investigate the impact of different psychological models, strategies, and methods to improve plaque control and/or gingival inflammation in patients with periodontal diseases. METHODS: The PubMed/MEDLINE, Cochrane Library, and Embase online databases were explored to identify relevant studies published before October 2022. Articles investigating the effects of different psychological approaches and intervention strategies on periodontitis patients' oral hygiene (OH) behavioral change were screened. RESULTS: 5460 articles were identified, and 21 fulfilled the inclusion criteria. In total, 2 studies tested audio-visual modalities, and the remaining 19 publications involved six psychological models of health-related behavioral interventions, including Social Cognitive Theory, the Theory of Planned Behavior, the Health Action Process Approach, Leventhal's self-regulatory theory, Motivational Interviewing, and Cognitive Behavioral Therapy. A meta-analysis of the results was not carried out due to the high heterogeneity among the interventions. CONCLUSIONS: Considering the limitations of the available studies, psychological interventions based on social cognitive models that combine some of the techniques of this model (goal setting, planning, self-monitoring, and feedback) may improve OH in periodontitis patients, having a positive impact on periodontal clinical outcomes. Delivering cognitive behavioral therapy in combination with motivational interviewing may result in an improvement in OH as evaluated by decreasing plaque and bleeding scores.
RESUMEN
OBJECTIVE: Multirooted teeth respond less favorably to non-surgical periodontal treatment and long-term tooth prognosis is influenced by the degree of furcation involvement (FI). Therapeutic strategy for multirooted teeth is essentially based on accurate diagnosis of the FI. The aim of this systematic review is to evaluate the accuracy of the different furcation assessment methods and to determine if radiographic help is needed to determine early stage of FI. METHODS: Electronic databases were searched up to March 2021. Comparative studies describing the reliability of different clinical and/or radiological furcation assessment methods were identified. RESULTS: A total of 22 studies comparing at least 2 furcation assessment methods, among which 15 retrospective studies, 5 prospective studies, 1 randomized controlled trial and 1 case series, were included in this review. The reliability of cone beam CT (CBCT), intraoral radiographs (IOs), orthopantomograms (OPGs) and MRI to identify FI was evaluated. Using OFS as a reference for FI detection and diagnosis, agreement ranged from 43.3 to 63% for OPG, 38.7 to 83.1% for IO and 82.4 to 84% for CBCT. The validity of the measurements was mainly influenced by the location of the furcation entrance. For radiological diagnosis, CBCT displayed the closest agreement with OFS while the accuracy of IO and OPG showed modest agreement and were influenced by the examiner's experience. CONCLUSION: Altogether, it appears that the use of IO, OPG or CBCT allows detection of FI but could not be considered as gold-standard techniques.

BACKGROUND: Porphyromonas gingivalis exacerbates tissue hypoxia and worsens periodontal inflammation. This study investigated the effect of a therapeutic oxygen carrier (M101), derived from Arenicola marina, on hypoxia and associated inflammation in the context of periodontitis. METHODS: The effect of M101 on GLUT-1, GLUT-3, HIF-1α, and MMP-9 expression, hypoxia, and antioxidant status in oral epithelial cells (EC) exposed to CoCl2 (1000 µM), P. gingivalis (MOI 100), and CoCl2 + P. gingivalis was evaluated through hypoxia detection fluorescence assay, antioxidant concentration colorimetric assay, and RTqPCR. Evaluation of M101 on EC proliferation was evaluated in an in vitro wound assay. In experimental periodontitis, periodontal wound healing and osteoclastic activity were compared among natural wound healing, placebo, and gels containing M101 (1 and 2 g/L) groups through histomorphometry and TRAP (tartrate-resistant acid phosphatase activity assay) assay respectively. The expression of HIF-1α, MMP-9, and NFκB in periodontal tissues was also evaluated through immunofluorescence studies. RESULTS: M101 downregulated GLUT-1, GLUT-3, HIF-1α, and MMP-9 levels in EC exposed to CoCl2 , P. gingivalis, and CoCl2 + P. gingivalis (p < 0.05). Fluorescence and colorimetric analyses confirmed hypoxia reduction and antioxidant capacity improvement in such EC upon M101 treatment. Moreover, M101 improved significantly the in vitro wound closure. In vivo, the attachment level was significantly improved, and osteoclastic activity was reduced in mice treated with M101 gels compared to placebo and natural wound healing groups (p < 0.05). HIF-1α, MMP-9, and NFκB expression in periodontal tissues was reduced in M101 gels treated mice compared to the controls. CONCLUSION: M101 showed promise in resolving hypoxia and associated inflammation-mediated tissue degradation. Its potential in the clinical management of periodontitis must be further investigated.

PURPOSES: The aim of this sytematic review was to evaluate the potential association of COVID-19 infection with oral health. MATERIALS AND METHODS: Screening in different databases (PubMed/MEDLINE, Google Scholar, and Embase databases) was performed to identify relevant articles, focusing on the oral health of patients with COVID-19, and published up to November 2021. 5194 articles were identified, and 29 fulfilled the inclusion criteria. RESULTS: Patients presenting more severe periodontal or dental diseases were at an increased risk of developing COVID-19 complications and being admitted to intensive care units. According to the included articles, U-shaped lingual papillitis and aphthous-like ulcers on the tongue are the most frequent lesions assessed in the oral cavity of COVID-19 patients, while xerostomia seems to be an early COVID-19 diagnostic symptom. Apart from the presence of the virus, the global lockdown had a detrimental impact on oral health. The occurrence of dental emergencies was augmented during this time due to the postponement of numerous non-emergency dental procedures. CONCLUSIONS: The presence of SARS-CoV-2 in periodontal tissues and salivary fractions may explain the presence of oral lesions during the infection. However, the virus's direct or indirect effect on oral mucosa is unclear. It is important to consider that these manifestations might be attributed to underlying comorbidities, or co-existing or subsequent lesions produced by local irritants.

The aim of this study was to evaluate the potential anti-inflammatory and anti-resorptive effects of lenabasum in the context of Porphyromonas gingivalis (Pg)-induced inflammation. Lenabasum or ajulemic acid (1',1'-dimethylheptyl-THC-11-oic-acid), a synthetic analog of THC-11-oic acid, has already demonstrated anti-inflammatory properties for the treatment of several inflammatory diseases. In vitro, the cytocompatibility of lenabasum was evaluated in human oral epithelial cells (EC), oral fibroblasts and osteoblasts by metabolic activity assay. The effect of lenabasum (5 µM) treatment of Pg-LPS- and P. gingivalis-infected EC on the pro- and anti-inflammatory markers was studied through RTqPCR. In vivo, lenabasum was injected subcutaneously in a P. gingivalis-induced calvarial abscess mouse model to assess its pro-healing effect. Concentrations of lenabasum up to 5 µM were cytocompatible in all cell types. Treatment of Pg-LPS and Pg-infected EC with lenabasum (5 µM; 6 h) reduced the gene expression of TNF-α, COX-2, NF-κB, and RANKL, whereas it increased the expression of IL-10 and resolvin E1 receptor respectively (p < 0.05). In vivo, the Pg-elicited inflammatory lesions' clinical size was significantly reduced by lenabasum injection (30 µM) vs untreated controls (45%) (p < 0.05). Histomorphometric analysis exhibited improved quantity and quality of bone (with reduced lacunae) and significantly reduced calvarial soft tissue inflammatory score in mice treated with lenabasum (p < 0.05). Tartrate-resistant acid phosphatase activity assay (TRAP) also demonstrated decreased osteoclastic activity in the treatment group compared to that in the controls. Lenabasum showed promising anti-inflammatory and pro-resolutive properties in the management of Pg-elicited inflammation, and thus, its potential as adjuvant periodontal treatment should be further investigated.

Current periodontal treatments aim to control bacterial infection and decrease inflammation. To optimize contemporary conventional treatments that present limitations owing to an inability to reach the lesion site, new methods are based on nanomedicine. Nanomedecine allows delivery of host-modulatory drugs or antibacterial molecules at the lesion site in an optimal concentration with decreased toxicity and risk of systemic side effects. Chitosan and polylactic-co-glycolic acid-loaded nanoparticles, carbon quantum dots, and mesoporous silicates open new perspectives in periodontitis management. The potential therapeutic impact of the main nanocarriers is discussed.

Control of inflammation is indispensable for optimal oral wound healing and tissue regeneration. Several biomaterials have been used to enhance the regenerative outcomes; however, the biomaterial implantation can ensure an immune-inflammatory response. The interface between the cells and the biomaterial surface plays a critical role in determining the success of soft and hard tissue regeneration. The initial inflammatory response upon biomaterial implantation helps in tissue repair and regeneration, however, persistant inflammation impairs the wound healing response. The cells interact with the biomaterials through extracellular matrix proteins leading to protein adsorption followed by recruitment, attachment, migration, and proliferation of several immune-inflammatory cells. Physical nanotopography of biomaterials, such as surface proteins, roughness, and porosity, is crucial for driving cellular attachment and migration. Similarly, modification of scaffold surface chemistry by adapting hydrophilicity, surface charge, surface coatings, can down-regulate the initiation of pro-inflammatory cascades. Besides, functionalization of scaffold surfaces with active biological molecules can down-regulate pro-inflammatory and pro-resorptive mediators' release as well as actively up-regulate anti-inflammatory markers. This review encompasses various strategies for the optimization of physical, chemical, and biological properties of biomaterial and the underlying mechanisms to modulate the immune-inflammatory response, thereby, promoting the tissue integration and subsequent soft and hard tissue regeneration potential of the administered biomaterial.
RESUMEN
Periodontal treatment could be worsened by risk factors. Depression and anxiety have been suggested as potentially influencing periodontal treatment outcomes. The aim of this study was to determine their association with non-surgical periodontal treatment outcomes in patients with generalized severe periodontitis (stage III/IV generalized periodontitis) at 6 months. A total of 68 patients diagnosed with generalized severe periodontitis were treated with scaling and root planing (SRP) and were followed at 3 and 6 months. The data of the 54 patients that followed the entire protocol were considered for analysis. Depression and anxiety levels were determined at baseline by the Beck Depression Inventory (BDI) and State-Trait Inventory (STAI) questionnaires. The association between psychological scores and periodontal parameters was evaluated by multivariate analysis. At 3 and 6 months, SRP induced an improvement for all periodontal parameters (plaque index (PI), bleeding on probing (BOP), periodontal probing depth (PPD) and clinical attachment loss (CAL)). BDI and STAI scores were associated with the evolution of PI, BOP, mean PPD and number of sites with PPD > 3 mm and with CAL > 3 mm. Depression and anxiety should be considered as risk factors for SRP and the identification of at-risk patients should be performed using well-established tools.

Periodontitis is an inflammatory disease associated with anaerobic bacteria leading to the destruction of tooth-supporting tissues. Porphyromonas gingivalis is a keystone anaerobic pathogen involved in the development of severe lesions. Periodontal treatment aims to suppress subgingival biofilms and to restore tissue homeostasis. However, hypoxia impairs wound healing and promotes bacterial growth within periodontal pocket. This study aimed to evaluate the potential of local oxygen delivery through the local application of a hydrogel containing Arenicola marina's hemoglobin (M101). To this end, a hydrogel (xanthan (2%), hyaluronic acid (1%)) containing M101 (1-2 g/L) (Xn(2%)-HA(1%)-M101) was prepared and characterized. Rheological tests revealed the occurrence of high deformation without the loss of elastic properties. Dialysis experiment revealed that incorporation of M101 within the gel did not modify its oxygen transportation properties. Samples of release media of the gels (1 g/L (10%) and 2 g/L (10%) M101) decreased significantly the growth of P. gingivalis after 24 h validating its antibacterial effect. Metabolic activity measurement confirmed the cytocompatibility of Xn(2%)-HA(1%)-M101. This study suggests the therapeutic interest of Xn(2%)-HA(1%)-M101 gel to optimize treatment of periodontitis with a non-invasive approach.

Periodontal Ehlers-Danlos syndrome (pEDS) is a rare condition caused by pathogenic variants in the C1R and C1S genes, encoding subunits C1r and C1s of the first component of the classical complement pathway. It is characterized by early-onset periodontitis with premature tooth loss, pretibial hyperpigmentation and skin fragility. Rare arterial complications have been reported, but venous insufficiency is rarely described. Here we report 13 novel patients carrying heterozygous pathogenic variants in C1R and C1S including three novel C1S variants (c.962G > C, c.961 T > G and c.961 T > A). In addition to the pEDS phenotype, three patients and one relative displayed widespread venous insufficiency leading to persistent varicose leg ulcers. One patient suffered an intracranial aneurysm with familial vascular complications including thoracic and abdominal aortic aneurysm and dissection and intracranial aneurysm rupture. This work confirms that vascular complications can occur, although they are not frequent, which leads us to propose to carry out a first complete non-invasive vascular evaluation at the time of the diagnosis in pEDS patients. However, larger case series are needed to improve our understanding of the link between complement pathway activation and connective tissue alterations observed in these patients, and to better assess the frequency, type and consequences of the vascular complications.

Purpose: Several studies demonstrated compromised oral health and periodontal diseases as risk factors for adverse pregnancy outcomes. However, consideration of oral health by pregnant women remains elusive. The aim of this study was to evaluate knowledge and behaviour of French pregnant women towards relationship between oral conditions and pregnancy outcomes and to evaluate influencing factors. Materials and Methods: A self-reported questionnaire was given to women between 1 and 3â¯days after delivery in three specialised clinics in France. The questionnaire aimed to evaluate demographic characteristics, self-perceived oral health, type of pregnancy follow-up and knowledge regarding oral conditions during pregnancy and risk of adverse pregnancy outcomes. A multivariate analysis was performed to evaluate correlation between knowledge and behaviour. Results: The questionnaire was completed by 212â¯women. Among them, 92% considered prevention of oral diseases during pregnancy important. Despite knowledge of potential negative influence of periodontal diseases on pregnancy outcomes, only 47% of pregnant women received dental diagnosis or treatment during pregnancy. Only 18% of the women discussed oral health consideration during pregnancy with health professional in charge of pregnancy follow-up. Interestingly, absence of dental consultation during pregnancy was associated with low rate of dental consultation prior to pregnancy (pâ¯<â¯0.01). Conclusions: Pregnant women were aware of the association between oral health and pregnancy and of need of prevention. However, consideration of importance of oral health was not adequate to the rate of dental consultation and seems to be influenced by individual dental follow-up habits prior to pregnancy. Clinical Relevance: Dental evaluation should be considered systematically during pregnancy follow-up.

Systemic lupus erythematosus (SLE) is an autoimmune multisystem disease with numerous clinical manifestations. There is no consensus about the ideal oral management for this group of patients to date. This review aimed to describe the broad spectrum of orofacial and clinical manifestations and their therapeutic approaches. Studies concerning orofacial manifestations of SLE and dental treatment modalities were selected by a literature search (1978-2019) using Google Scholar, PubMed/MEDLINE electronic databases. The initial search strategy provided a total of 129 articles, and of these, 30 were included for qualitative synthesis. The reviewed studies revealed that SLE patients are more at risk of compromised oral and dental health exhibiting increased risk of periodontal diseases and temporomandibular joint disorders. The use of systemic drugs especially immunosuppressive and anticoagulants in SLE patients may also influence their oral management. Results emphasize the need to carry out, at an early stage of the disease, an appropriate oral management of these patients to improve oral health-related quality of life and to prevent the need of more invasive therapeutics. A multidisciplinary approach is needed for dental and medical management of such patients.

BACKGROUND: The aim of this study was to evaluate the influence of psychological stress on non-surgical periodontal treatment (SRP) outcomes in patients with severe chronic periodontitis (stage 3/4 generalized periodontitis) at 6 months in the French population. METHODS: Patients diagnosed with severe generalized chronic periodontitis (periodontitis stage 3/4) were included in this study. At baseline, psychological status was evaluated by self-administered questionnaire (Depression Anxiety Stress Scale 42 [DASS-42] and Toulouse coping scale [TCS]). Plasma levels of cortisol and chromogranin-A were determined. Patients were then managed by oral hygiene instructions, scaling and root planing of sites with PD >3 mm and followed at 3 and 6 months. Quantitative and qualitative variables were described and interactions were determined by linear and logistic regressions. RESULTS: Seventy-one patients were included in this study and 54 were followed up to 6 months. An average probing depth (PD) reduction of 0.73 ± 0.11 mm and decrease of diseased sites (PD >3 mm) were measured at 6 months illustrating SRP efficacy. Multivariable analysis showed that increased DASS-stress score was associated to worsened SRP outcomes in terms of bleeding on probing (BOP) (OR = 1.02, P <0.05) and mean PD (P <0.05) reduction. An increase of DASS-depression score negatively influenced PD >5 mm (OR = 1.06, P <0.05), PD >7 mm (OR = 1.17, P <0.01), CAL >5 mm (OR = 1.03, P <0.05), and CAL >7 mm (OR = 1.07, P <0.05) reduction. Negative coping strategies were also associated with worsened SRP outcomes. CONCLUSIONS: Patients with increased stress, anxiety, and depression scores as well as those exhibiting negative coping strategies demonstrate worsened SRP outcomes. DASS-42 and TCS were useful to determine psychological status and their use could be incorporated to assess treatment prognosis.

Periodontitis is an infectious inflammatory disease characterized by clinical attachment loss and tooth supporting tissue destruction. As exosomes demonstrated pro-regenerative ability, their use in periodontal treatment has been suggested. The aim of this systematic review is to gather and summarize the most recent data regarding exosomes to determine their potential impact in bone and periodontal regeneration. Electronic databases (Pubmed, Web of Science) were searched up to February 2020. Studies assessing the impact of exosomes administration in experimental bone and periodontal defects have been identified according to PRISMA guidelines. Among the 183 identified articles, 16 met the inclusion criteria and were included in this systematic review. Experimental bone defects were mainly surgically induced with a dental bur or distraction tools. All studies considered bone healing after exosomes administration as the primary outcome. Results showed that mesenchymal stem cells derived exosomes administration promoted bone healing and neovascularization. Nevertheless, a dose-effect relationship was observed. Exosomes administration appears to promote significantly the bone healing and periodontal regeneration. However, only a limited number of studies have been carried out so far and the optimized protocols in this context need to be evaluated.

OBJECTIVES: The purpose of this systematic review was to determine the potential interest of parathyroid hormone (PTH) as an adjunct to periodontal treatment based on studies performed in rodents. MATERIALS & METHODS: Electronic databases (MEDLINE, Web of Science) were searched up to December 2019. Studies assessing the impact of PTH administration in experimental periodontitis in rodents have been identified. RESULTS: Amongst the 247 identified articles, 10 met the inclusion criteria and were included in this systematic review. Experimental periodontitis was mainly induced by ligature placement or surgically with a dental bur. All studies considered bone healing after PTH administration at different frequencies as primary outcome. Results showed that an intermittent administration of PTH promoted bone healing and neovascularization. Nevertheless, a decrease of soft tissue inflammation was also observed. CONCLUSION: Intermittent administration of PTH appears to enhance significantly periodontal healing and to promote alveolar bone regeneration. However, due to the risk of side effects, the development of scaffolds allowing its local and time-controlled delivery is of importance.

The control of inflammation and infection is crucial for periodontal wound healing and regeneration. M101, an oxygen carrier derived from Arenicola marina, was tested for its anti-inflammatory and anti-infectious potential based on its anti-oxidative and tissue oxygenation properties. In vitro, no cytotoxicity was observed in oral epithelial cells (EC) treated with M101. M101 (1 g/L) reduced significantly the gene expression of pro-inflammatory markers such as TNF-α, NF-κΒ and RANKL in P. gingivalis-LPS stimulated and P. gingivalis-infected EC. The proteome array revealed significant down-regulation of pro-inflammatory cytokines (IL-1ß and IL-8) and chemokine ligands (RANTES and IP-10), and upregulation of pro-healing mediators (PDGF-BB, TGF-ß1, IL-10, IL-2, IL-4, IL-11 and IL-15) and, extracellular and immune modulators (TIMP-2, M-CSF and ICAM-1). M101 significantly increased the gene expression of Resolvin-E1 receptor. Furthermore, M101 treatment reduced P. gingivalis biofilm growth over glass surface, observed with live/dead analysis and by decreased P. gingivalis 16 s rRNA expression (51.7%) (p < 0.05). In mice, M101 reduced the clinical abscess size (50.2%) in P. gingivalis-induced calvarial lesion concomitant with a decreased inflammatory score evaluated through histomorphometric analysis, thus, improving soft tissue and bone healing response. Therefore, M101 may be a novel therapeutic agent that could be beneficial in the management of P. gingivalis associated diseases.

The effectiveness of adjunctive photodynamic treatment (PDT) to non-surgical periodontal therapy has been shown to depend on initial periodontal status. As molar furcation involvement impairs healing response to non-surgical periodontal therapy, the aim of this study was to evaluate the impact of furcation involvement on PDT outcomes. Thirty-six patients suffering from severe chronic periodontitis were included in a 6-month split-mouth randomized clinical trial. PDT applications used the toluidine blue O and a light-emitting diode (LED) with a red spectrum. Repeated PDT applications were performed in addition to non-surgical periodontal treatment at baseline and at 3-months. Pocket probing depth (PPD), plaque index, bleeding on probing, and clinical attachment level were recorded at baseline, and again at 3- and 6-months. Furcation sites of molars were compared to other sites of molars and non-molars. Multilevel analysis showed no PDT effect in molar furcation sites while an additional significant reduction (odds ratio = 0.67) of pockets with PPD > 5 mm in other sites at 3-months was measured. PPD reduction appeared delayed in molar furcation sites treated with PDT. There is no additional apparent benefit to use PDT in molar furcation sites for the reduction of pockets with PPD > 5 mm contrary to other sites.
