Randomized Controlled Trials Assessing Exposure Frequency Effects of Stannous Fluoride on Gingivitis.

OBJECTIVE: To evaluate the exposure frequency effect of 0.454% stannous fluoride (SnF2) toothpaste in controlling gingivitis. METHODS: Two randomized controlled trials enrolled generally healthy adults with gingivitis. The study duration was 1 mo (study 1) and 3 mo (study 2). Gingivitis was assessed using the Löe-Silness Gingival Index (LSGI) at baseline, 1 mo (both studies), and 3 mo (study 2); bleeding scores were derived from the LSGI. Study groups consisted of positive control (twice-daily use of 0.454% SnF2 toothpaste), experimental group (brushing in the morning with SnF2 toothpaste and in the evening with 0.76% sodium monofluorophosphate [SMFP] toothpaste), and negative control (twice-daily use of SMFP toothpaste). The primary endpoint was number of bleeding sites. RESULTS: Study 1 and study 2 each enrolled and randomized 90 participants; 86 and 89 participants, respectively, completed the trials. At baseline, the mean (SD) number of bleeding sites was 47.6 (18.54) in study 1 and 41.5 (17.84) in study 2. At 3 mo (study 2), the positive control produced 51.3% fewer bleeding sites, and the experimental group produced 32.5% fewer bleeding sites versus the negative control (P < 0.001 for both). At 1 mo, the positive control produced 45.1% (study 1) and 45.8% (study 2) fewer bleeding sites versus the negative control (P < 0.001 for both), and the experimental group produced 33.0% (study 1) and 24.8% (study 2) fewer bleeding sites, respectively, versus the negative control (P ≤ 0.002 for both). The benefit was observed as early as 1 mo and was consistent with 3-mo results. CONCLUSION: This research is to our knowledge the first to demonstrate a gingivitis-reduction response effect for the frequency of bioavailable SnF2 toothpaste use, with maximum benefit from twice-daily use, followed by a single-daily exposure versus the negative control. Clinical trial registration numbers: NCT05916508 and NCT05916521. KNOWLEDGE TRANSFER STATEMENT: The results of this study can be used by dental professionals to guide their recommendations for therapeutic toothpaste for gingival health. Emphasis on the importance of twice-daily brushing with bioavailable stannous fluoride dentifrice will help patients optimize gingival health benefits achieved via self-care.

The Clinical Incorporation of the 2017 Classification of Periodontal Disease Conditions Part II: The Association Between Clinical Parameters and Gender.

Background The implementation of the new classification system guided clinicians in the best way for disease diagnosis and patient management. The advent of definitions such as clinical gingival health additionally helped in distinguishing between intact and reduced periodontium. The purpose behind introducing new systems was to guide practitioners to improve on managing the requirements of the patients effectively. It also enables professionals to concentrate on clinical practice, and it can be suggested that readers who are concentrating on research make use of the global classification system. In this study, we present a diagnostic approach for periodontal diseases that supports the innovative classification system in relation to gender while remaining compatible with previous guidelines. Aim The present study focuses on the relationship between gender association and the clinical parameters in periodontitis patients that would support the new classification system. Materials and methods This was a retrospective, cross-sectional, observational study consisting of patient data obtained from past patient records who were diagnosed with periodontitis. Results The data analysis results showed that 95% of the population was similarly distributed across the genders in terms of frequency, and there was minimal statistically significant difference between the genders when compared to the clinical parameters. However, there was a statistically significant difference in the specific clinical characteristics, such as recession, which impacted 48.6% of male patients, and the presence of local factors, which affected 43.2% of female patients, in addition to the 59.4% localized involvement of periodontitis. All the data were analyzed using the SPSS software version 20 (IBM SPSS Statistics, Armonk, NY). The chi-square test was used to evaluate the descriptive analysis and frequency tables. Conclusion The addition of correlating clinical parameters with data based on gender had no effect on the new classification system. Meanwhile, it can be used as an adjunct to evaluate the distribution and extent of disease progression among genders.

Salivary and serum inflammatory biomarkers during periodontitis progression and after treatment.

AIM: To identify serum- and salivary-derived inflammatory biomarkers of periodontitis progression and determine their response to non-surgical treatment. MATERIALS AND METHODS: Periodontally healthy (H; n = 113) and periodontitis patients (P; n = 302) were monitored bi-monthly for 1 year without therapy. Periodontitis patients were re-examined 6 months after non-surgical periodontal therapy (NSPT). Participants were classified according to disease progression: P0 (no sites progressed; P1: 1-2 sites progressed; P2: 3 or more sites progressed). Ten salivary and five serum biomarkers were measured using Luminex. Log-transformed levels were compared over time according to baseline diagnosis, progression trajectory and after NSPT. Significant differences were sought using linear mixed models. RESULTS: P2 presented higher levels (p < .05) of salivary IFNγ, IL-6, VEGF, IL-1ß, MMP-8, IL-10 and OPG over time. Serum analytes were not associated with progression. NSPT led to clinical improvement and significant reduction of IFNγ, IL-6, IL-8, IL-1ß, MMP-8, IL-10, OPG and MMP-9 in saliva and of CRP, MMP-8, MMP-9 and MPO in serum. CONCLUSIONS: Periodontitis progression results from a sustained pro-inflammatory milieu that is reflected in salivary biomarkers, but less so in serum, likely because of the limited amount of progression per patient. NSPT can significantly decrease the levels of several salivary analytes.

Periodontitis and Diabetes Complications: A Danish Population-Based Study.

Conflicting evidence suggests a link between diabetes-related microvascular complications and periodontitis. Reliable estimates have been hindered by small sample sizes and residual confounding. Moreover, the combined effects of microvascular complications and dyslipidemia on periodontitis have not been explored. Therefore, this study aimed to investigate the association between individual and combined diabetic microvascular complications (i.e., neuropathy and retinopathy) and moderate/severe periodontitis in a Danish population-based study. In addition, we assessed whether dyslipidemia modified these associations. This study comprised 15,922 participants with type 2 diabetes from the Health in Central Denmark study. Multinomial logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for individual and joint microvascular diabetes complications. The models adjusted for potential confounders, including sociodemographic factors, lifestyle behaviors, and health conditions. Inverse probability of treatment weighting (IPTW) balanced measured confounders between periodontitis and nonperiodontitis participants. Sensitivity analyses tested the findings' robustness by estimating E-values for unmeasured confounding and varying microvascular complication definitions. After IPTW, adjusted models revealed that diabetic neuropathy (OR 1.36, 95% CI 1.14 to 1.63) and retinopathy (OR 1.21, 95% CI 1.03 to 1.43) were significantly associated with moderate/severe periodontitis. Moreover, the coexistence of microvascular complications increased the odds 1.5-fold for moderate/severe periodontitis (OR 1.51, 95% CI 1.23 to 1.85). An effect modification of dyslipidemia on an additive scale was found, indicated by a positive relative excess risk due to interaction of 0.24 for neuropathy, 0.11 for retinopathy, and 0.44 for both complications. Sensitivity analysis ruled out unmeasured confounders and microvascular complication definitions as explanatory factors. Diabetic neuropathy and retinopathy, individually and combined, were associated with moderate/severe periodontitis. In addition, dyslipidemia had an additive positive effect modification on diabetic microvascular complications, elevating the odds of moderate/severe periodontitis. These findings may aid in identifying at-risk subgroups for diabetes-related microvascular complications and periodontitis, optimizing efforts to mitigate disease burden.

Ten-year changes of periodontitis grading using direct and indirect evidence: a retrospective evaluation.

OBJECTIVE: To evaluate two methods for assessing the changes in periodontitis grading in patients undergoing supportive periodontal therapy (SPT) ten years (T10) after retrospective baseline (BL) grading. MATERIALS AND METHODS: The periodontitis grade of 51 SPT-patients was assessed using indirect evidence as the primary criterion for periodontitis progression at BL and T10 (radiographic bone loss/age index, periodontitis phenotype). Grading at T10 was also performed using the direct evidence for periodontitis progression (clinical attachment loss over the previous five years). The use of indirect evidence for periodontal progression at BL and T10 was defined as method 1 (M1) to assess the changes in periodontitis grading. The use of indirect evidence at BL and direct evidence at T10 was defined as method 2 (M2). Changes in periodontitis grading using M1 and M2 were evaluated (Wilcoxon signed-rank test). Agreement between M1 and M2 was assessed (Cohen's kappa). RESULTS: Indirect BL-grading revealed five grade B and 46 grade C patients. The indirect grading at T10 revealed 17 grade B and 34 grade C patients. The direct T10-grading classified all patients as grade C. M1 led to an overall improvement in periodontitis grading after ten years of SPT (p=0.00297), whereas M2 led to a deterioration (p=0.0369). The comparison between M1 and M2 showed that they lead to different results in terms of grading (Cohen's Kappa=0.116208). CONCLUSIONS: Periodontitis grading may change during SPT. Using indirect or direct evidence as the primary grading criterion during SPT may lead to different results.

Insulin resistance and periodontitis: Mediation by blood pressure.

AIM: This study investigated the association between the triglyceride-glucose (TyG) index, a surrogate marker of insulin resistance, and moderate/severe periodontitis and the role of blood pressure as a mediator in this association. A second aim was to assess the role of cardiometabolic conditions such as obesity, hypertension, and dyslipidemia as potential effect modifiers. METHODS: Data from 5733 US adults aged 30-64 years and with complete periodontal examination were analyzed (NHANES 2011-2014). Participants were classified as having moderate/severe periodontitis or mild/no periodontitis according to the CDC/AAP criteria as the outcome. The exposure was the TyG index, while both systolic (SBP), and diastolic (DBP) blood pressure were tested as mediators using parametric g-formula. Analyses were adjusted for relevant confounders, namely, age, sex, ethnicity, poverty-income ratio, and smoking, using inverse probability treatment weighting. Obesity status (based on a body mass index ≥30 kg/m2), self-report of hypertension and dyslipidemia (calculated based on the thresholds provided by National Cholesterol Education Program-Adult Treatment Panel-III) were tested as effect modifiers. RESULTS: The findings showed the TyG index to be associated with increased odds of moderate/severe periodontitis [odds ratio (OR), 95% confidence interval (CI) = 1.17 (1.11-1.23)], with 50% of the total effect mediated by SBP. Stratified analysis showed a stronger association in individuals with obesity, hypertension, and dyslipidemia compared to those without these conditions. However, in those taking anti-hypertensive medications, the association was partially mitigated. Sensitivity analysis using imputed data showed consistent results. CONCLUSION: The TyG index was associated with increased odds of moderate/severe periodontitis, especially in individuals with obesity, hypertension, and dyslipidemia. SBP levels partially mediated this association.

Study of microRNAs in Gingival Crevicular Fluid as Periodontal Diseases Biomarkers: Systematic Review.

AIM: The aim of this review was to identify the microRNAs (miRNAs) present in gingival crevicular fluid (GCF) that can be used as biomarkers for the diagnosis of periodontal diseases, and to determine which of them has a higher diagnostic yield for periodontitis. METHODS: The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines (reference number CRD42024544648). The Pubmed, Scopus, Cochrane Library, Embase, Web of Science, and Google Scholar databases were searched for clinical studies conducted in humans investigating periodontal diseases and miRNAs in GCF. The methodological quality of the articles was measured with the Newcastle-Ottawa Scale. RESULTS: A total of 3222 references were identified in the initial literature search, and 16 articles were finally included in the review. The design of the studies was heterogeneous, which prevented a meta-analysis of the data. Most of the studies compared miRNA expression levels between patients with periodontitis and healthy controls. The most widely researched miRNA in periodontal diseases was miR-200b-3p and miR-146a. CONCLUSIONS: the miRNAs most studied are miR-146a, miR-200b, miR-223, miR-23a, and miR-203, and all of them except miR-203 have an acceptable diagnostic plausibility for periodontitis.

"The effects of non-surgical periodontal treatment plus zinc and magnesium supplementation on oxidative stress and antioxidants enzymes in type 2 diabetes patients: a quasi-experimental study".

BACKGROUND: Periodontal Disease (PD) associated with Type 2 Diabetes Mellitus (T2DM) is a chronic condition that affects the oral cavity of people living with T2DM. The mechanisms of the interaction between type 2 Diabetes Mellitus and Periodontal diseases are complex and involve multiple pathophysiological pathways related to the systemic inflammatory process and oxidative stress. Non-surgical periodontal treatment (NSTP) is considered the standard for the management of this disease; however, patients with systemic conditions such as type 2 Diabetes Mellitus do not seem to respond adequately. For this reason, the use of complementary treatments has been suggested to support non-surgical periodontal treatment to reduce the clinical consequences of the disease and improve the systemic conditions of the patient. The use of zinc gluconate and magnesium oxide as an adjunct to non-surgical periodontal treatment and its effects on periodontal clinical features and oxidative stress in patients with Periodontal diseases -type 2 Diabetes Mellitus is poorly understood. METHODS: A quasi-experimental study was performed in patients with periodontal diseases associated with T2DM. Initially, 45 subjects who met the selection criteria were included. 19 were assigned to a control group [non-surgical periodontal treatment] and 20 to the experimental group (non-surgical periodontal treatment + 500 mg of magnesium oxide and 50 mg of zinc gluconate for oral supplementation for 30 days) and the data of 6 patients were eliminated. Sociodemographic characteristics, physiological factors, biochemical parameters, and clinical features of periodontal diseases were assessed. RESULTS: In this research a change in periodontal clinical characteristics was observed, which has been associated with disease remission. Additionally, a shift in MDA levels was presented for both groups. Furthermore, the supplementation group showed an increase in antioxidant enzymes when compared to the group that only received NSPT. CONCLUSION: The use of Zinc gluconate and magnesium oxide can serve as a complementary treatment to non-surgical periodontal treatment, that supports the remission of PD as a result of regulation-reduction of oxidative biomarkers and increase in antioxidant enzymes activity.

Exploring the accuracy of tooth loss prediction between a clinical periodontal prognostic system and a machine learning prognostic model.

AIM: The aim of this analysis was to compare a clinical periodontal prognostic system and a developed and externally validated artificial intelligence (AI)-based model for the prediction of tooth loss in periodontitis patients under supportive periodontal care (SPC) for 10 years. MATERIALS AND METHODS: Clinical and radiographic parameters were analysed to assign tooth prognosis with a tooth prognostic system (TPS) by two calibrated examiners from different clinical centres (London and Pittsburgh). The prediction model was developed on the London dataset. A logistic regression model (LR) and a neural network model (NN) were developed to analyse the data. These models were externally validated on the Pittsburgh dataset. The primary outcome was 10-year tooth loss in teeth assigned with 'unfavourable' prognosis. RESULTS: A total of 1626 teeth in 69 patients were included in the London cohort (development cohort), while 2792 teeth in 116 patients were included in the Pittsburgh cohort (external validated dataset). While the TPS in the validation cohort exhibited high specificity (99.96%), moderate positive predictive value (PPV = 50.0%) and very low sensitivity (0.85%), the AI-based model showed moderate specificity (NN = 52.26%, LR = 67.59%), high sensitivity (NN = 98.29%, LR = 91.45%), and high PPV (NN = 89.1%, LR = 88.6%). CONCLUSIONS: AI-based models showed comparable results with the clinical prediction model, with a better performance in specific prognostic risk categories, confirming AI prediction model as a promising tool for the prediction of tooth loss.

Interrupted time series analysis of chronic periodontitis-related procedures before and after the scaling reimbursement policy in Korea.

AIM: To study the use of a quasi-experimental design to assess the effects of scaling reimbursement policies on the incidence of chronic-periodontitis procedures. MATERIALS AND METHODS: Interrupted time series analysis was used to compare the effects before and after policy implementation using data on the number of periodontitis-related procedures from the Korean National Health Insurance Service-National Sample Cohort (n = 740,467) and the Health Screening Cohort (n = 337,904). Periodontitis-related procedures with diagnosis codes were categorized into basic (scaling or root planing), intermediate (subgingival curettage) and advanced (tooth extraction, periodontal flap surgery, bone grafting for alveolar bone defects or guided tissue regeneration). Subjects' demographics and comorbidities were considered. The incidence rate of immediate changes and gradual effects before and after policy implementation was assessed. RESULTS: Following the policy implementation from July 2013, an immediate increase was observed in total and basic procedures. No significant changes were noted in intermediate and advanced procedures initially. A decrease in the slope of intermediate procedures was observed in both databases. Advanced procedures showed varied trends, with no change in the National Sample Cohort but an increase in the Health Screening Cohort, particularly among subjects with comorbidities. CONCLUSIONS: Following the new policy implementation, the number of intermediate procedures decreased while the number of advanced procedures increased, especially among patients with comorbidities. These findings offer valuable insights on policy evaluation.

Performance of ChatGPT in classifying periodontitis according to the 2018 classification of periodontal diseases.

OBJECTIVES: This study assessed the ability of ChatGPT, an artificial intelligence(AI) language model, to determine the stage, grade, and extent of periodontitis based on the 2018 classification. MATERIALS AND METHODS: This study used baseline digital data of 200 untreated periodontitis patients to compare standardized reference diagnoses (RDs) with ChatGPT findings and determine the best criteria for assessing stage and grade. RDs were provided by four experts who examined each case. Standardized texts containing the relevant information for each situation were constructed to query ChatGPT. RDs were compared to ChatGPT's responses. Variables influencing the responses of ChatGPT were evaluated. RESULTS: ChatGPT successfully identified the periodontitis stage, grade, and extent in 59.5%, 50.5%, and 84.0% of cases, respectively. Cohen's kappa values for stage, grade and extent were respectively 0.447, 0.284, and 0.652. A multiple correspondence analysis showed high variance between ChatGPT's staging and the variables affecting the stage (64.08%) and low variance between ChatGPT's grading and the variables affecting the grade (42.71%). CONCLUSIONS: The present performance of ChatGPT in the classification of periodontitis exhibited a reasonable level. However, it is expected that additional improvements would increase its effectiveness and broaden its range of functionalities (NCT05926999). CLINICAL RELEVANCE: Despite ChatGPT's current limitations in accurately classifying periodontitis, it is important to note that the model has not been specifically trained for this task. However, it is expected that with additional improvements, the effectiveness and capabilities of ChatGPT might be enhanced.

Comparative effects of e-cigarette smoking on periodontal status, salivary pH, and cotinine levels.

BACKGROUND: The nicotine in e-cigarette liquid can negatively impact periodontal tissues by altering the salivary pH and elevating cotinine levels. Thus, the study aimed to determine the periodontal parameters, salivary pH, and cotinine levels among cigarette, e-cigarette, and never-smokers. METHODS: A total of 144 participants were recruited (48 cigarette smokers, 48 e-cigarette smokers, and 48 never-smokers). Clinical periodontal parameters, including plaque index (PI), gingival index (GI), periodontal probing pocket depth (PPD), and clinical attachment loss (CAL) were recorded, excluding third molars. The level of unstimulated whole salivary pH was measured using a portable pH meter and the levels of salivary cotinine were measured using Enzyme-Linked Immunosorbent Assay (ELISA). RESULTS: Data were analysed statistically using analysis of variance. Mean scores of PPD, percentage of pocket depth ≥ 4 mm, and CAL (p < 0.05) were significantly higher among cigarette smokers than those in e-cigarette and never-smokers, while GI (p < 0.05) were significantly higher among e-cigarette smokers. The unstimulated salivary pH was more acidic among cigarette smokers (p < 0.05) and e-cigarette smokers (p < 0.05) than in never-smokers. The cotinine levels were higher among cigarette smokers (p < 0.05) and e-cigarette smokers (p < 0.05) than in never-smokers. CONCLUSIONS: Clinical periodontal parameters were poorer in cigarette smokers than in e-cigarette smokers and never-smokers. Meanwhile, cigarette and e-cigarette smokers have more acidic salivary pH and higher cotinine levels than in never-smokers.

The Role of Different Types of Cannabinoids in Periodontal Disease: An Integrative Review.

This integrative review addresses the potential of the Endocannabinoid System (ES) and cannabinoids in the pathogenesis and treatment of periodontal disease (PD). Cannabinoid receptors are expressed in healthy and inflamed periodontal tissues, indicating a potential regulatory role for SEC in oral homeostasis. Healthy periodontal cells express more CB1 receptors, while inflamed sites show increased CB2 receptors. This suggests a dynamic involvement of the SEC in the inflammatory response associated with PD. Cannabinoids such as cannabidiol (CBD) and cannabinoid receptor agonists such as HU-308, anandamide (AEA), and methanamide (Meta-AEA) have demonstrated promising therapeutic potential in studies. CBD has been associated with the control of bone resorption, antibacterial activity, and increased production of gingival fibroblasts, indicating effects in mitigating the progression of PD. HU-308 demonstrated preventive effects against alveolar bone loss, and anti-inflammatory, osteoprotective, and pro-homeostatic properties in animal models of periodontitis. AEA and Meta-AEA have anti-inflammatory effects by reducing pro-inflammatory mediators such as IL-1, IL-6, and TNF-α. The activation of cannabinoid receptors attenuates inflammatory processes, inhibits alveolar bone loss, exerts antibacterial effects, and promotes tissue repair. However, clinical trials are especially needed to validate these results and explore the therapeutic potential of cannabinoids in the treatment of PD in humans.

Comprehensive assessment of periodontal health in cerebral palsy: A systematic review and meta-analysis.

AIMS: Cerebral palsy (CP) is the term for a set of neurological disorders resulting from brain damage that impairs motor function. The aim of the present study was to perform a systematic review of the literature to determine whether individuals with CP are at a greater risk of negative periodontal health outcomes compared to those without CP. METHODS: This study followed the recommendations of the MOOSE guidelines. Electronic searches were conducted in the PubMed, Web of Science, Scopus, Ovid, Embase, and PsycInfo databases. Observational studies assessing periodontal outcomes in individuals with CP were included. Risk of bias was appraised using the Newcastle-Ottawa scale. Meta-analyses were conducted and the results were presented using standardized mean differences (SMD), odds ratios (OR), and 95% confidence intervals (CI). The strength of the evidence was also assessed. RESULTS: A total of 316 records were retrieved from the electronic databases, 17 of which were included in the qualitative synthesis. Meta-analyses revealed significantly higher scores in individuals with CP compared to those without CP for the oral hygiene index (SMD = 0.47 [95% CI: 0.17-0.78, I2 = 80%), gingival index (SMD = 0.75 [95% CI: 0.39-1.11], I2 = 79%), plaque index (SMD = 0.70 [95% CI: 0.07-1.33], I2 = 93%), and calculus index (SMD = 0.98 [95% CI: 0.76-1.20], I2 = 0%). However, no significant difference was found between groups for the prevalence of gingivitis (OR = 1.27 [95% CI: 0.28-5.66], I2 = 93%). The risk of bias for the outcome assessment and statistical tests was low. The strength of the evidence was deemed very low. CONCLUSION: Individuals with CP may experience more significant negative periodontal health outcomes compared to those without CP.

Association between nonalcoholic fatty liver disease scores and chronic periodontitis: A retrospective cohort study.

BACKGROUND: Although several studies have demonstrated a bidirectional relationship between nonalcoholic fatty liver disease (NAFLD) and chronic periodontitis, few studies have reported that NAFLD causes chronic periodontitis, especially in the Asian population. METHODS: This study was conducted on 129,087 individuals, and the NAFLD score was assessed using the Fatty Liver Index (FLI), Hepatic Steatosis Index (HSI), and Framingham Steatosis Index (FSI). The incidence of chronic periodontitis was defined as a diagnostic code with dental procedures. Multi-variable adjusted Cox proportional hazard regression analysis was performed with hazard ratio (HR) and 95% confidence intervals (CIs). RESULTS: Nine thousand one hundred and twenty-eight chronic periodontitis cases (7.1%) were identified during a mean 7.4 years follow-up period. Each NAFLD score was related to chronic periodontitis. In the FLI score, HR and 95% CIs for the incidence of chronic periodontitis compared with a low FLI group were as follows: indeterminate FLI: 1.19 (1.12-1.26), high FLI: 1.32 (1.18-1.47). In the HSI and FSI scores, HR and 95% CIs for the incidence of chronic periodontitis were 1.13 (1.05-1.22) and 1.23 (1.05-1.31), respectively. CONCLUSIONS: All NAFLD scores were associated with chronic periodontitis in the Korean population. As chronic periodontitis can aggravate the liver status, patients with NAFLD may need regular dental visits.

Oral health inequalities in immigrant populations worldwide: a scoping review of dental caries and periodontal disease prevalence.

BACKGROUND: Inequalities in immigrants' oral health are often masked in population-level data. Therefore, this paper was planned to assess the prevalence data on oral health diseases, namely dental caries, and periodontitis, among immigrants worldwide. METHODS: Following a systematic search in Scopus, Embase, and PubMed for studies published between 2011 and 2023, 1342 records were identified. Following title and abstract screening, 76 studies remained for full-text eligibility-screening based on predefined inclusion criteria. Thirty-two studies were included in the review. RESULTS: Dental caries figures were higher in immigrant populations compared to the local population, regardless of host countries, age, gender, or nationality. In children, the overall mean and standard deviation (SD) for decayed, missing, and filled teeth in the primary dentition (d3mft) was 3.63(2.47), and for D3MFT (permanent dentition), it was 1.7(1.2). Upon comparing overall mean caries counts in children and adults with their control groups in the included studies, untreated dental caries (D3T and d3t) constituted the dominant share of caries experience (D3MFT and d3mft) in immigrant children. For the local population, the highest proportion of caries experience was attributed to filled teeth (FT and ft). Dentin caries prevalence among immigrants ranged from 22% to 88.7% in the primary dentition and 5.6% to 90.9% in the permanent dentition. Gingivitis ranged from 5.1% to 100%. Oral health varied greatly between studies. Regarding oral health accessibility, 52% to 88% of immigrant children had never been to a dentist, suggesting a very limited level of accessibility to dental health services. CONCLUSION: It is imperative to develop interventions and policies that have been customized to address the oral health disparities experienced by immigrant populations. Additionally, host countries should actively implement measures aimed at enhancing the accessibility of oral health care services for these individuals. The utilization of available data is crucial in establishing a hierarchy of objectives aimed at enhancing the oral health of immigrant populations. TRIAL REGISTRATION: The Scoping review protocol was registered at OSF Registries with registration number ( https://doi.org/10.17605/OSF.IO/MYXS4 ).

The Influence of Dental Status and Blood Parameters Characterizing Endogenous Intoxication on the Timing of Childbirth.

Background and Objectives: Epidemiological and microbiological-immunological studies have led to the conclusion that periodontal disease may be a risk factor for preterm birth. The aim of this study was to investigate and identify the relationship of some hematological cellular biomarkers characterizing the chronic oral focus of infection with pregnancy outcomes and their impact on those outcomes. Materials and Methods: Clinical and laboratory tests were conducted on 100 pregnant women, grouped by full-term or preterm births, with the assessment of the following markers: DMF, CPI and PIRI, PHP, microbiological examination of periodontal pockets and amniotic fluid, WBS count, WBCSI, LGI, and NMR. A statistical analysis was carried out with SPSS Statistics version 19.0. Results: Women with preterm labor had higher-grade caries (CSL > 0.3), while women with full-term childbirth had moderate caries (CSL < 0.3). A satisfactory level of oral hygiene efficiency was found in 50% (group 1) and 38.1% (group 2) of the expectant mothers. The periodontal status by the PIRI showed tissue lesions in 20.7% (group 1) and 92.9% (group 2) of the women. The WBCSI was 2.27 ± 0.82 and 2.15 ± 0.68, the NMR was 9.29 ± 5.119 and 11.62 ± 7.78, and the LGI was 3.54 ± 1.1 and 3.73 ± 0.81 in groups 1 and 2, respectively. Comparative analysis of bacterial contamination of the amniotic fluid revealed the predominance of Fusobacterium nucleatum (64.3%), Tannerella forsythia (57.1%), Prevotella intermedia (50%), Porphyromonas gingivalis (57.1%), Staphylococcus aureus (45.2%), and Candida albicans (50%) in women with premature birth. Conclusions: In women with preterm birth, the values of the indices characterizing a chronic oral focus of infection evoke more significant correlations with the timing of delivery, which indicates the significant role of an oral focus of infection. The presence of microbial invasion of amniotic fluid may indicate the role of periodontopathogenic bacteria in pregnant women diagnosed with a risk of preterm birth.

Correlation Between Body Mass Index and Periodontitis: A Clinical and Biochemical Analysis.

Introduction Obesity is the excessive deposition of body fat in relation to lean body mass. In this research, its relation to periodontitis has been analysed using clinical and biochemical parameters. The current study assessed the correlation between body mass index (BMI) and periodontitis using salivary visfatin levels. Materials and methods Sixty participants (33 males and 27 females) were categorised into three different groups according to BMI: group 1: normal weight (n=20); group 2: overweight (n=20); and group 3: obese (n=20). Clinical parameters such as probing pocket depth (PPD) and clinical attachment level (CAL) were recorded. Salivary samples were collected and assessed for salivary visfatin levels with the aid of a human visfatin enzyme-linked immunosorbent assay (ELISA) kit. The results were assessed using IBM SPSS Statistics for Windows, Version 23.0 (Released 2015; IBM Corp., Armonk, New York, United States). Results The PPD, CAL, and salivary visfatin levels were higher in group 3, followed by groups 2 and 1, and were statistically significant (p=0.000). The correlation between visfatin and PPD (r=0.962) and visfatin and CAL (r=0.978) was strongly positive and statistically significant. Conclusion This study demonstrates a strong positive correlation between BMI and periodontitis. Moreover, salivary visfatin can be considered a diagnostic marker for periodontal diseases.

Alcohol and Periodontal Disease: A Narrative Review.

The scientific literature dealing with alcohol and alcoholic beverages revealed that these drinks possess an adverse impact on periodontal tissues. Additionally, other principal risk factors include tobacco, smoking, poor oral hygiene, etc. It has been observed that among chronic alcoholics, there are further issues, such as mental, social, and physical effects, that promote alcoholism. These people may have weak immunity for defense against pathogenic organisms and bacteria. Thus, chances of gingival bleeding, swollen gums, bad breath, and increased bone loss are there. Different alcoholic beverages in the market cause less salivation; these beverages contain sugars that promote acid production in the oral cavity by pathogens that demineralize the enamel and damage gum and teeth. This chronic alcohol consumption can progress into different types of oral disorders, including cancer, halitosis, and caries, and is also associated with tobacco and smoking. Chronic alcohol consumption can cause alteration of the oral microbiome and increase oral pathogens, which lead to periodontal disease and an environment of inflammation created in the body due to malnutrition, diminished immunity, altered liver condition, brain damage, and gut microbiota alteration. Heavily colored alcoholic beverages produce staining on teeth and, due to less saliva, may cause other toxic effects on the periodontium. Over-dependency on alcohol leads to necrotizing lesions such as necrotizing gingivitis, necrotizing periodontitis, and necrotizing stomatitis. These pathological impairments instigate severe damage to oral structures. Therefore, proper counseling by the attending dental surgeon and related health professionals is urgently required for the patient on the basis that the individual case needs to go away from the regular heavy consumption of alcohol.

Natural Bioactive Compounds in the Management of Periodontal Diseases: A Comprehensive Review.

Periodontal diseases, chronic inflammatory conditions affecting oral health, are primarily driven by microbial plaque biofilm and the body's inflammatory response, leading to tissue damage and potential tooth loss. These diseases have significant physical, psychological, social, and economic impacts, necessitating effective management strategies that include early diagnosis, comprehensive treatment, and innovative therapeutic approaches. Recent advancements in biomanufacturing have facilitated the development of natural bioactive compounds, such as polyphenols, terpenoids, alkaloids, saponins, and peptides, which exhibit antimicrobial, anti-inflammatory, and tissue regenerative properties. This review explores the biomanufacturing processes-microbial fermentation, plant cell cultures, and enzymatic synthesis-and their roles in producing these bioactive compounds for managing periodontal diseases. The integration of these natural compounds into periodontal therapy offers promising alternatives to traditional treatments, potentially overcoming issues like antibiotic resistance and the disruption of the natural microbiota, thereby improving patient outcomes.
