    Abstract Background: The aim of the present study was to evaluate the subgingival microbiome in patients with grade C molar-incisor pattern periodontitis (C-MIP) affecting the primary or permanent dentitions.
    Methods: DNA was isolated from subgingival biofilm samples from diseased and healthy sites from 45 C-MIP patients and subjected to phylogenetic microarray analysis. C-MIP sites were compared between children affected in the primary to those affected in the permanent dentitions. Within-subject differences between C-MIP-affected sites and dentition-matched healthy sites were also evaluated.
    Results: C-MIP sites of subjects affected in the primary dentition showed partially overlapping but distinct microbial communities from C-MIP permanent dentition sites (p < 0.05). Differences were due to increased levels in primary C-MIP sites of certain species of the genera Capnocytophaga and Leptotrichia, while C-MIP permanent dentition sites showed higher prevalence of Filifactor alocis. Aggregatibacter actinomycetemcomitans (Aa) was among species seen in high prevalence and levels in both primary and permanent C-MIP sites. Moreover, both permanent and primary C-MIP sites showed distinct microbial communities when compared to dentition-matched healthy sites in the same subject (p < 0.01).
    Conclusions: Primary and permanent teeth with C-MIP showed a dysbiotic microbiome, with children affected in the primary dentition showing a distinct profile from those affected in the permanent dentition. However, Aa was enriched in both primary and permanent diseased sites, confirming that this microorganism is implicated in C-MIP in both dentitions.

    Abstract The biological mechanisms underlying the pathogenesis of type 2 diabetes (T2DM)-related periodontitis remain unclear. This cross-sectional study evaluated the distinctive transcriptomic changes between tissues with periodontal health and with periodontitis in patients with T2DM. In this cross-sectional study, whole transcriptome sequencing was performed on gingival biopsies from non-periodontitis and periodontitis tissues from non-diabetic and diabetic patients. A differentially expressed gene (DEG) analysis and Ingenuity Pathway Analysis (IPA) assessed the genes and signaling pathways associated with T2DM-related periodontitis. Immunohistochemistry was performed to validate selected DEGs possibly involved in T2DM-related periodontitis. Four hundred and twenty and one thousand five hundred and sixty-three DEGs (fold change ≥ 2) were uniquely identified in the diseased tissues of non-diabetic and diabetic patients, respectively. The IPA predicted the activation of Phagosome Formation, Cardiac β-adrenergic, tRNA Splicing, and PI3K/AKT pathways. The IPA also predicted the inhibition of Cholesterol Biosynthesis, Adrenomedullin, and Inositol Phosphate Compounds pathways in T2DM-related periodontitis. Validation of DEGs confirmed changes in protein expression of PTPN2, PTPN13, DHCR24, PIK3R2, CALCRL, IL1RN, IL-6R and ITGA4 in diseased tissues in diabetic subjects. Thus, these preliminary findings indicate that there are specific genes and functional pathways that may be involved in the pathogenesis of T2DM-related periodontitis.

    Abstract Introduction: Cognitive impairment and frailty are prevalent in older persons. Physical frailty is associated with cognitive decline; however, the role of effect modifiers such as age, sex, race/ethnicity, and cognitive reserve is not well understood.
    Methods: Cross-sectional data from the National Health and Nutrition Examination Survey (2011-2014) were obtained for participants aged ≥60 years. Complete availability of cognitive scores was an inclusion criterion. Physical frailty was defined by the presence of exhaustion, weakness, low body mass, and/or low physical activity, and categorized into three groups: robust (0 present), pre-frail (1-2 present), or frail (3-4 present). Four cognitive test scores were converted to z-scores, and global cognition (composite z-score) was calculated by averaging the four-individual z-scores. Multivariable linear regression models were fit to estimate the associations between frailty and cognitive function. Frailty was also evaluated as a risk factor for self-reported subjective memory complaint (SMC) using logistic regression. All models were adjusted for age, sex, race/ethnicity, education, alcohol use, income, marital status, diabetes, hypertension, and history of stroke. Effect measure modification analyses were conducted by age, sex, race/ethnicity, education, and occupational cognitive demand.
    Results: The study population comprised 2,863 participants aged ≥60 years. 50.6% of the participants were categorized into robust, 43.2% pre-frail, and 6.2% frail. After adjusting for covariates, compared to robust participants, frail and prefrail participants had lower adjusted mean global cognitive z-scores, <inline-formula><mml:math id="m1" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mover accent="true"><mml:mi>β</mml:mi><mml:mo>^</mml:mo></mml:mover></mml:mrow></mml:math></inline-formula> = -0.61, 95% CI: -0.83, -0.38 and <inline-formula><mml:math id="m2" xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mover accent="true"><mml:mi>β</mml:mi><mml:mo>^</mml:mo></mml:mover></mml:mrow></mml:math></inline-formula> = -0.21, 95% CI: -0.30, -0.12, respectively. Both prefrail and frail participants had higher odds of SMC compared to the robust participants. We did not see strong evidence that the association between frailty and cognition was modified by the factors we studied.
    Discussion/conclusion: Both pre-frailty and frailty were associated with lower cognitive performance and were more likely to report subjective memory complaints relative to persons without frailty. These findings provide additional evidence that physical frailty may serve as a prognostic factor for cognitive deterioration or dementia, and prevention of frailty may be an important public health strategy.

    Abstract FBXO11 is the substrate-recognition component of a ubiquitin ligase complex called SKP1-cullin-F-boxes. The role of FBXO11 in bone development is unexplored. In this study, we reported a novel mechanism of how bone development is regulated by FBXO11. FBXO11 gene knockdown by lentiviral transduction in mouse pre-osteoblast MC3T3-E1 cells leads to reduced osteogenic differentiation, while overexpressing FBXO11 accelerates their osteogenic differentiation in vitro. Furthermore, we generated two osteoblastic-specific FBXO11 conditional knockout mouse models, Col1a1-ERT2-FBXO11KO and Bglap2-FBXO11KO mice. In both conditional FBXO11KO mouse models, we found FBXO11 deficiency inhibits normal bone growth, in which the osteogenic activity in FBXO11cKO mice is reduced, while osteoclastic activity is not significantly changed. Mechanistically, we found FBXO11 deficiency leads to Snail1 protein accumulation in osteoblasts, leading to suppression of osteogenic activity and inhibition of bone matrix mineralization. FBXO11 knockdown in MC3T3-E1 cells reduced Snail1 protein ubiquitination and increased Snail1 protein accumulation in the cells, which eventually inhibited osteogenic differentiation. In conclusion, FBXO11 deficiency in osteoblasts inhibits bone formation through Snail1 accumulation, inhibiting osteogenic activity and bone mineralization.

    Abstract Background: The aim of this study was to determine the clinical and inflammatory response patterns for individual siblings diagnosed with grade C molar-incisor pattern periodontitis (C-MIP) and between the related siblings within families.
    Methods: Sixty-nine siblings within 28 families with moderate-to-severe C-MIP were included. Clinical parameters were evaluated for symmetry regarding the affected type of teeth, side and/or arch, and bone loss pattern. The protein concentrations from in vitro whole blood cultures for 14 different lipopolysaccharide-stimulated inflammatory markers were correlated with the extent and severity of disease, within an individual sibling and among siblings within a family.
    Results: A similar disease pattern was observed among all siblings and within families. The most common teeth affected were first molars and incisors or first molars only within the permanent dentition and only molars within the primary dentition (p < 0.001). Symmetry involving molars was higher than in incisors in siblings, regardless of arch or side affected (p = 0.020). Arc-shape/vertical bone defects were the most common (p = 0.006) and higher symmetry was found for these defects in the permanent dentition (p = 0.005). Positive correlations were found between age, clinical attachment loss, and percent affected sites with several inflammatory markers. The inflammatory responses for several inflammatory markers were correlated within and among families (p < 0.050). Specifically, the intraclass correlation coefficient within families was highest (>0.5) for interleukin (IL)-8, IL-6, and IL-10.
    Conclusions: Families with C-MIP presented similar patterns of disease. The level of an inflammatory response to bacteria seemed to play a role in the extent and severity of this disease, exemplified by the high degree of correlation in these families.

    Abstract Objective: Our study aimed to determine the relationship of antidepressant medicine use with periodontal diseases, exploring the association of different pharmacological classes of antidepressant with observations of clinical attachment loss (CAL) and alveolar bone level (BL) in patients with periodontitis.
    Background: Existing evidence on the impact of antidepressant medication on periodontal tissues has focused on some classes only and is still unclear. Therefore, this retrospective study evaluated the association of different antidepressant classes with clinical attachment loss (CAL) and alveolar bone level (BL).
    Methods: This study was carried out in a population of patients aged ≥ 30 years old with periodontitis who sought treatment at the University of Florida from 2014 to 2018. The following variables were obtained from patients' records; usage of antidepressant medications and their pharmacological classes (selective serotonin reuptake inhibitors [SSRI], serotonin-norepinephrine reuptake inhibitors [SNRI], tricyclic, atypical, and monoamine oxidase inhibitors [MAO]), age, gender, smoking habit, mild systemic diseases, CAL, and cement-enamel junction (CEJ) and alveolar bone crest (BC) distance, defined as BL, in the Ramfjord index teeth.
    Results: Five hundred and eighty-two periodontitis patients were evaluated, of which 113 (19.4%) were antidepressant users. Antidepressant users exhibited significantly lower BL and fewer sites with severe CAL (≥5 mm), than non-users (p < .05). Among all single-class antidepressant users, the SSRI users showed significantly less CAL and lower BL than non-users (p < .05). Patients taking combinations of the different classes of antidepressants also showed better CAL and BL than non-users. Generalized linear models, including variables such as gender, age, systemic diseases, and smoking, demonstrated that antidepressant users were more likely to have lower mean BL and fewer sites with severe bone loss (i.e. BL > 3 and >5 mm) than non-users (p < .05).
    Conclusions: Antidepressant medications were associated with higher alveolar bone level and less clinical attachment loss in patients with periodontitis. When the different classes of antidepressants were analyzed individually, only the SSRI class users and the multiple-class users showed significantly less periodontal breakdown than non-users.

    Abstract Background: This single-center, randomized controlled trial aimed to determine the effectiveness of a novel, biofilm-disrupting, mouth rinse that combines Cetylpyridinium chloride (CPC) and essential oils in preventing re-accumulation of supragingival plaque and supragingival microbiome in patients with gingivitis after dental prophylaxis.
    Methods: One hundred eighteen participants were randomly assigned in a 1:1 ratio to receive twice-daily test mouth rinse (59) or carrier rinse control (59) for 12 weeks after dental prophylaxis.
    Results: In a per-protocol analysis that included patients who completed the intervention, the treatment group (39) had significantly lower supragingival plaque scores at 6 and 12 weeks compared to the control group (41; p = 0.022). Both groups showed similar improvement in gingivitis score, but neither group had improvement in bleeding score or probing depth. Thirty-eight (29%) patients did not complete the study due to loss of follow-up (17) or early discontinuation of the assigned intervention (21). Microbiome sequencing showed that the treatment rinse significantly depleted abundant and prevalent members of the supragingival plaque microbiome consortium.
    Conclusions: Among patients with gingivitis, the novel mouth rinse significantly reduced re-accumulation of supragingival plaque following dental prophylaxis by depleting supragingival plaque microbiome. However, long-term adherence to the rinse may be limited by adverse effects ( ClinicalTrials.gov number, NCT03154021).
