Abstract
BACKGROUND Periodontal diseases can negatively impact the oral health-related quality of life (OHRQoL) of pregnant women. This study investigates the association between maternal oral inflammatory load (OIL), sociodemographic characteristics, and the OHRQoL in postpartum women. METHODS In this cross-sectional study, breastfeeding mothers were recruited from St. Michael's Hospital, Toronto within 2-4 weeks postpartum. Mothers were categorized into "Normal/low" and "High" OIL groups based on the absolute counts of oral polymorphonuclear neutrophils (oPMNs). The Oral Health Impact Profile-14 questionnaire was used to assess the impact of the maternal OIL on the OHRQoL. Multiple linear regression analyses were performed to examine the association between maternal sociodemographic factors including age, marital status, education level, employment status, parity, and their OHRQoL. RESULTS Forty-seven mothers were included in this study. Mothers with high OIL reported higher impact on their OHRQoL (30%) than mothers with normal/low OIL (21%), but these differences were not statistically different. There was a negative relationship between the mother's education level and the extent of impact of OHRQoL on the "physical pain" dimension (p < 0.05), and between the mothers' age and employment status and the "physical disability" dimension (p < 0.05). A positive correlation was noted between multi-parity and the extent of impact of OHRQoL on the "physical disability" dimension (p = 0.009), and between the marital status and the "psychological disability" dimension (p < 0.05). CONCLUSION This study highlighted the significant impact of sociodemographic characteristics on the OHRQoL of mothers, showcasing the importance of considering these factors when implementing targeted preventive dental care programs for mothers.

The association between oral inflammatory load and semen and sperm functional analysis: A cross-sectional study. J Dent Res Dent Clin Dent Prospects 2023; 17:188-195. [PMID: 38023802 PMCID: PMC10676540 DOI: 10.34172/joddd.2023.37106] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2023] [Accepted: 08/15/2023] [Indexed: 12/01/2023] Open
Abstract
Background Studies have suggested a correlation between periodontitis and reduced male fertility. Inflammation has been described as the link between these ailments. Oral inflammatory load (OIL) can be measured through oral polymorphonuclear neutrophil (oPMN) count, which is associated with periodontal diseases. This cross-sectional study assessed the possible correlation between OIL and the functional parameters of sperm cells. Methods In 229 volunteers, oral rinse and semen samples were assessed for oPMN, semen polymorphonuclears (sPMNs), sperm concentration, total sperm count, motility, morphology, and sperm DNA fragmentation index (SDFi). A multiple linear regression model was conducted to evaluate the relationships between oPMN and semen parameters. Results The effect of elevated oPMN counts on total motility rate, progressive rate, and percentage of sperm cells with normal morphology was significant (P<0.001), with an inverse relationship, i.e., with every unit increase in oPMN count, the mentioned parameters would decline by 0.573, 0.367, and 0.407 units, respectively. oPMN counts also correlated positively with sPMN counts and SDFi (P<0.001), i.e., with every unit increase in the oPMN measures, sPMN counts would increase by 0.126 million/mL, with an 0.733% increase in SDFi. However, there was no significant association between oPMN counts and sperm concentration. Conclusion OIL, as represented by oPMN counts, might affect male fertility as there is a positive correlation between the levels of these inflammatory cells and decreased sperm motility, abnormal morphological changes, increased sPMN counts, and increased SDFi.

Abstract
Background The periodontium is a highly vascularized area of the mouth, and periodontitis initiates negative functional and structural changes in the vasculature. However, mild oral inflammation, including levels experienced by many apparently healthy individuals, has an unclear impact on cardiovascular function. The purpose of this pilot study is to investigate the effects of objectively measured whole mouth oral inflammatory load (OIL) on vascular function in apparently healthy individuals. Methods In this cross-sectional and correlational analysis, we recruited 28 young (18-30 years) and systemically healthy participants (16 male, 12 female). Using oral neutrophil counts, a validated measure for OIL, we collected participant's mouth rinse samples and quantified OIL. Blood pressure, arterial stiffness (pulse-wave velocity) and endothelial function (brachial artery flow-mediated dilation) were also measured. Results Only oral neutrophil count significantly predicted flow-mediated dilation % (p = 0.04; R2 = 0.16, β = - 1.05) and those with OIL levels associated with >2.5 × 105 neutrophil counts (n = 8) had a lower flow-mediated dilation % (6.0 ± 2.3%) than those with counts associated with gingival health with less than 2.5 × 105 neutrophil counts (10.0 ± 5.2%, p = 0.05). There were no significant predictors for arterial stiffness. Conclusion We found that OIL was a predictor of reduced flow-mediated dilation. An impairment in flow-mediated dilation is an indicator of future possible risk of cardiovascular disease-one of the leading causes of death in North America. Therefore, this study provides evidence for the importance of oral health and that OIL may impact endothelial function.

Abstract
BACKGROUND Periodontal disease and pregnancy outcomes have been claimed to be associated with conflicting reports. The purpose of this study was to prospectively examine the association between maternal periodontal status, oral inflammatory load and serum C- reactive protein (CRP) level, and infant birth weight. METHODS A total of 156 pregnant women (age 26.62 ± 3.93 years) within the gestational age group of 13 to 32 weeks participated in this cross-sectional study. Oral inflammatory load (OIL) was assessed in a salivary rinse sample using fluorescence microscopy. Clinical periodontal parameters were recorded and serum C-reactive protein level (CRP) was assessed. Participants were followed till delivery, details of parturition and infant birth weight (IBW) was recorded. RESULTS OIL was significantly more in participants with mild and moderate periodontitis as compared to those with gingivitis in mid and late stages of pregnancy. Periodontal and systemic inflammatory parameters were positively correlated. A significant negative correlation was found between IBW and OIL (P = 0.006) and serum CRP (P < 0.001). The GI score (P = 0.039), BOP% (P = 0.023), serum CRP level (P < 0.001) and oral polymorphonuclear neutrophil (oPMN) count (P < 0.001) was significantly more in mothers delivering babies with low IBW. A multiple linear regression analysis showed that only oPMN (β = - 0.244, P = 0.021) and serum CRP (β = - 0.226, P = 0.019) were included in the best model (R2 = 0.12, F(3,152) = 7.15, P < 0.001) for significantly predicting the infant birth weight. CONCLUSIONS Poor maternal periodontal status, increased oral inflammatory load and increased systemic inflammation have an adverse effect on infant birth weight.

Abstract
Periodontal diseases present a significant challenge to our healthcare system in terms of morbidity from the disease itself as well as their putative and deleterious effects on systemic health. The current method of diagnosing periodontal disease utilizes clinical criteria solely. These are imprecise and are somewhat invasive. There is thus significant benefit to creating a non-invasive test as a method of screening for and monitoring of periodontal diseases, and, in particular, chronic periodontitis. Oral polymorphonuclear neutrophil (oPMN) counts have been found to correlate with extent of oral inflammation and the presence and severity of periodontal diseases. Potentially then, quantification of oPMNs might be used to identify and measure the severity of oral inflammation (oral inflammatory load; OIL) in subjects with healthy and inflamed periodontal tissues, demonstrating a positive correlation between higher oPMN counts and the extent/severity of OIL. These findings support the development and utilization of a non-invasive chair-side test enabling rapid, accurate, and objective screening of OIL based on measurement of oPMN numbers (similar to white blood cell levels in blood as used in medicine for assessment of infection). The use of such a test before, during, and after treatment of gingivitis and periodontitis could lead to improvements in timing of intervention (ie, when inflammation is active) thereby reducing long-term morbidity.

Abstract
BACKGROUND There have been several past reports that adults with intellectual disabilities experience poor oral health (tooth loss, periodontal health and untreated dental caries). Loss of a functional dentition has serious consequences, including problems with chewing, swallowing, nutrition, speech, temporomandibular joint osteoarthritis and pain and systemic health conditions. Poor oral health is largely preventable through proactive oral care support. In recent years, social care provision for adults has changed, with deinstitutionalisation and home-based personalised care now being the typical provision in high income countries. Hence, oral health inequalities might be reducing. However, there is limited recent evidence-synthesis on the topic. We aimed to address this. METHOD PROSPERO registration number: CRD42018089880. We conducted a preferred reporting items for systematic reviews and meta-analyses systematic review of publications since 2008. Four databases were searched with a clear search strategy, strict inclusion criteria for selection of papers, double scoring (two raters), systematic data extraction and quality appraisal of included papers. RESULTS A total of 33/3958 retrieved articles were included, of which 14 were drawn from dental service users and 10 from Special Olympic athletes, therefore not necessarily being representative of the wider population with intellectual disabilities. Despite this limitation, adults with intellectual disabilities were still shown to experience poor oral health. High levels of poor oral hygiene and gingivitis were found, with many also affected by periodontitis and untreated dental decay. There is clear unmet need relating to both periodontal (gum) and tooth health, leading to tooth loss. CONCLUSIONS Despite reports in the past of poor oral health amongst adults with intellectual disabilities, and despite it being preventable, there remains a high burden of poor oral health. This highlights the need to raise awareness, and for polices on effective daily oral care, and appropriate service provision. The importance of oral health and its possible negative sequelae needs to be elevated amongst carers and professionals.

Abstract
Background Maintaining oral health is a continuous and dynamic process that also involves the immune system. Polymorphonuclear neutrophils (PMNs) migrate from blood circulation and become apparent in the oral fluid. Controversies exist regarding the specific role of the oral PMNs (oPMNs) in the presence of chronic oral inflammation, such as periodontitis. In this study we characterized cell counts, activation status, apoptosis, and reactive oxygen species (ROS) generation by oPMNs and circulatory (cPMNs), and the salivary protease activity, in subjects with and without periodontitis. Methods Venous blood and oral rinse samples were obtained from 19 patients with untreated periodontitis and 16 control subjects for PMN isolation. Apoptosis and expression of cell activation markers CD11b, CD63, and CD66b were analyzed using flow cytometry. Constitutive ROS generation was detected using dihydrorhodamine123. Additionally, ROS production in response to stimulation was evaluated in samples incubated with 10 μM phorbol myristate acetate (PMA) or Fusobacterium nucleatum. Total protease activity was measured using substrate PEK-054. Results Periodontitis patients presented with over 4 times higher oPMN counts compared to controls (p = 0.007), which was a predictor for the total protease activity (r2 = 0.399, P = 0.007). More oPMNs were apoptotic in periodontitis patients compared to the controls (P = 0.004). All three activation markers were more expressed on the oPMNs compared to the cPMNs (p < 0.05), and a higher expression of CD11b on the oPMNs from periodontitis patients was observed compared to the control subjects (P = 0.024). Constitutive ROS production per oPMN was higher compared to the cPMN (P < 0.001). Additional analysis showed that the oPMNs retained their ability to respond to stimulation, with no apparent differences between the periodontitis and control subjects. Conclusions Higher numbers of oral PMNs, being more apoptotic and having increased levels of degranulation markers were found in periodontitis compared to periodontal health. However, since the oPMNs in periodontitis were responsive to ex vivo stimulation, we conclude that the oPMNs are active in the oral ecosystem. It is currently unknown whether the oPMN counts, which correlated with the detected protease levels, are detrimental in the long term for the oral mucosa integrity. Trial registration This study was retrospectively registered at the ISRCTN registry (trial ID ISRCTN15252886). Registration date August 11, 2017.

Abstract
The first part of this two part series discussed the potential barriers and risk factors that may lead to an increased incidence and severity of periodontal disease amongst patients with learning disabilities. Additionally, preventive strategies and tools that can be used by general dental practitioners, oral health promotion teams as well as specialists within the field to control and prevent disease progression were explored. To prevent periodontal disease progression and attain optimal periodontal health, a combination of prevention and professional mechanical instrumentation is usually required. The second part of the series concentrates on the role of the dental professional in implementing professional mechanical instrumentation to attempt to reduce the burden of disease further in this patient group. Clinical relevance: Although research continues into which professional techniques for instrumentation are the most successful amongst patients with periodontal disease, very little data specifically explore the needs of patients with learning disabilities, despite their high unmet needs. This paper aims to report on any available data present to produce suggestions for care.

Abstract
Polymorphonuclear neutrophils (PMNs) have a major role in the innate immune system. However, little is known about PMN contribution in relation to oral health. The objective of this study was to investigate the numbers and functional characteristics of oral PMNs (oPMNs) compared with circulatory PMNs (cPMNs). Oral rinse and venous blood samples were obtained from 268 systemically and orally healthy volunteers in a cross-sectional observational study. PMN counts, cell cycle analysis and cellular activation state were investigated. Also, reactive oxygen species (ROS) production was analyzed, with and without bacterial stimulation (Fusobacterium nucleatum). In males, 1.2 × 106±1.0 × 106 oPMNs were collected, and showed a tendency to correlate with the levels of gingival bleeding (r=0.215, P=0.008). Comparable oPMNs counts were found among females (1.0 × 106±0.7 × 106). More late-stage apoptotic/necrotic cells were found among the oPMNs (53.1%) compared with the cPMNs (8.5% P<0.001). Without additional stimulation, oPMNs were more activated than cPMNs, as indicated by higher expression of CD11b, CD63 and CD66b, and higher constitutive ROS levels (P<0.001). Notably, in response to bacterial stimulation, oPMNs released comparable ROS levels as cPMNs (P=0.042). In conclusion, this study provides data on viable oPMNs showing high levels of activation in orally and systemically healthy individuals, free of apparent caries lesions and periodontal disease. These data suggests that although the oPMNs are in a more mature stage of their life cycle compared with the cPMNs, oPMNs are still responsive to stimulation, which indicates their functional potential and possible contribution to a healthy oral ecosystem.
