RESUMO
Sleep is fundamental for health and well-being. An adequate amount and quality of sleep is a cardinal component of a healthy lifestyle at the basis of the prevention of many non-communicable chronic diseases. Recent evidence suggests that sleep disorders, particularly obstructive sleep apnea, represent an emerging risk factor for periodontal health. This review article provides a critical appraisal of the existing literature concerning the association between sleep duration, sleep quality, sleep disorders in general, and obstructive sleep apnea with periodontal diseases, including gingivitis and periodontitis. The putative mechanisms underlying these associations are described as well as the potential clinical implications for diagnosis and treatment.
RESUMO
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.
RESUMO
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.
RESUMO
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.

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.

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.
RESUMO
BACKGROUND: Microbiomics offers new methods for conducting epidemiological surveys of oral microbiota in large populations. Compared to curette sampling, swab sampling is more convenient and less technically sensitive, making it more suitable for such surveys. To verify the feasibility of using swabs for buccal mucosa sampling in large-scale studies, we collected samples from the buccal mucosa and tooth surfaces of healthy individuals using both swabs and curettes. Microbiomics was employed to analyze and compare microbial abundance and diversity between these two methods. METHODS: Four sites were assessed: the buccal mucosa on both sides and the buccal surfaces of the left and right mandibular first molars. Two sampling methods, swab and curette, were used to collect bacterial communities from healthy individuals. Specifically, buccal mucosa samples (n = 10) and tooth surface samples (n = 20) were analyzed using 16 S rDNA gene sequencing. Bacterial signals were detected through fluorescence in situ hybridization (FISH), targeting the bacterial 16 S rDNA gene. Metastats analysis and Wilcoxon test were used. RESULTS: A total of 383 OTUs were detected in the 30 samples, which belonged to 1 kingdom (bacteria), 11 phyla, 23 classes, 40 orders, 75 families, 143 genus, and 312 species. Among them, 223 OTUs were found on both the buccal mucosa and tooth surfaces. The statistics suggest that although there were no significant differences in colony composition, there were differences in the abundance and distribution of colonies on the dental and buccal mucosal surfaces. When detecting oral disease-causing pathogens such as Enterococcus faecalis and Porphyromonas gingivalis, the efficiency of detection is higher when using curette sampling. Compared to right tooth sampling with a curette, the swab sampling group had higher levels of Firmicutes, while Fusobacteria and Bacteroidetes were more prevalent in the curette tissues. CONCLUSIONS: In oral health individuals, there is no difference in the bacterial composition of the oral buccal mucosa and the dental surface, differing only in abundance. Thus, the buccal mucosa can act as a substitute for the teeth in epidemiological investigations exploring the bacterial composition of the oral cavity.

Objective: Periodontal diseases are chronic inflammatory disorders influenced by systemic health of the individual. This study aimed to investigate the association between hypothyroidism and periodontal disease in a cohort of adult Saudi population. Methods: This case-control study included 201 adults with hypothyroidism on hormone replacement therapy and 188 healthy controls. The medical files of patients were reviewed to check thyroid stimulation hormone (TSH) and free thyroxine (FT4) levels. Participants completed a questionnaire on demographic and health information, followed by a comprehensive periodontal examination. Pearson chi-square and binary logistic regression analyses determined associations, with a significance set at p ≤0.05. Results: Gingivitis was found in 20.9% of cases and 58% of controls. Periodontitis stages I, II, III and IV were in general higher in cases compared to controls (23.4%, 27.9%, 21.9%, 6% in cases versus 13.8%, 17%, 9.6%, 1.6% in controls, respectively). Mean PPD and CAL values were higher in cases (5.54 ± 2.5 and 3.88 ± 3.1) than in controls (4.03 ± 1.6 and 1.72 ± 2.4). Significant associations between periodontal status and hypothyroidism were found (p < 0.0001). The periodontal status in hypothyroid cases correlated significantly with hormone replacement therapy dose and duration (p < 0.0001). Conclusion: The findings of the current study showed that, in a cohort of adult Saudi subjects, patients with hypothyroidism have higher prevalence and more severe periodontal disease symptoms compared to controls, suggesting significant association.
RESUMO
Traditional plastic surgery techniques for root coverage using connective tissue grafts are often invasive and cause patient discomfort. A new procedure with a minimally invasive approach for gingival recession was developed and termed the "root and cervical margin flattening procedure." A blunt incision was performed in the buccal gingival sulcus at the alveolar bone crest with a dissector or raspatory. After the incision, a split-thickness flap was dissected extending beyond the mucogingival junction, palpating the alveolar bone crest with a periodontal probe and flattening the cervical region and roots to smooth out irregularities along the dental root. In some complicated cases, more reliable effects were expected using a periodontal tissue regeneration drug and protective splint. The creeping attachment distance reached the flattened area. Careful blood clot preservation was crucial in the postoperative period. The gingival creeping attachment implied two main factors. First, surgical invasion could promote healing. Second, soft tissue space was increased due to root flattening. This simple and minimally invasive approach for treating cervical lesions (including non-carious cervical lesions and cervical/root caries) and gingival recession could obviate the need for connective tissue grafts. Further clinical studies are required to assess its success and prognosis.
RESUMO
OBJECTIVES: Although mechanical oral hygiene is widely practiced, it faces several challenges. Mouthwashes, such as chlorhexidine (CHX), are being explored as adjuncts to biofilm control, but their prolonged use has several side effects. Consequently, there is ongoing research into natural alternatives. This randomized crossover clinical study aimed to compare the antiplaque and antigingivitis efficacy of 0.12% CHX and a 5% Malva sylvestris METHODS: Forty-four participants were involved in two phases, each comprising three stages with variations in the mouthwash solution used only. During the study, participants refrained from mechanical plaque removal for seven days. At first day, they received whole-mouth prophylaxis and oral health assessment. After three days, gingival inflammation assessment and prophylaxis in were performed in contralateral quadrants. Participants then used a randomly assigned mouthwash solution for four days. On the 7th day, they completed a questionnaire about their perception and appreciation of the mouthwash. Additionally, gingival inflammation and plaque index were also performed by a calibrated examiner. After a minimum 21-day washout period, participants entered the second phase, repeating the three stages RESULTS: Results showed no statistically significant differences between the Malva sylvestris and CHX groups regarding inflammation and plaque formation. However, CHX demonstrated a significantly greater mean reduction (7th - 4th day) in gingival inflammation compared to Malva (p=0.02) (0.01±0.19 and 0.00±0.19, respectively). Additionally, participants using CHX reported a more pleasant taste and considered higher plaque control perception (p<0.05) CONCLUSIONS: In conclusion, both products exhibited similar antiplaque effects, but CHX outperformed Malva in controlling gingival inflammation. CLINICAL SIGNIFICANCE: Mouthwashes with Malva sylvestris may be a good alternative, in a short-term period, to control biofilm. However, lower antigingivitis efficacy may be expected when compared to chlorhexidine.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
Periodontitis is a chronic inflammatory disease that affects about 45 %-50 % of adults worldwide, but the efficacy of current clinical therapies is unsatisfactory due to the complicated periodontal immune microenvironment. Thus, developing drugs that can regulate innate immune cells (e.g., macrophages) is a potent strategy to treat periodontitis. Here, we report that phloretin, a food plant-derived natural compound, is sufficient to alleviate periodontitis through immune regulation. In vivo, phloretin treatment could significantly reduce alveolar bone resorption and periodontal inflammation in mouse periodontitis models. In vitro, phloretin could suppress proinflammatory (M1-like) polarization and cytokine release in macrophages induced by LPS. Mechanistically, the immune regulatory role of phloretin in macrophages may be due to its metabolic regulation effect. Phloretin might restore the balance of M1/M2 macrophage transition in periodontitis by inhibiting HIF-1α-mediated glycolysis and PI3k/Akt pathways, thereby reducing the proinflammatory effect and immune disorder caused by over-activated M1 macrophages. Together, this study highlights that natural compound, such as phloretin, can restore periodontal immune homeostasis by metabolic regulation of macrophages, which may provide novel insight into the treatment of periodontitis.
RESUMO
Background/Objectives: Mortality due to various non-communicable diseases, including hypertension, is increasing globally. Studies have reported that periodontitis, a chronic inflammatory disorder caused by oral pathogens, is a potential risk factor for hypertension. These pathogens can invade arterial walls, leading to vascular inflammation and endothelial dysfunction, which then increases the likelihood of developing hypertension. However, evidence of the association between periodontitis and hypertension remains limited. Therefore, the aim of this study is to determine whether periodontitis is associated with hypertension among adults in Rwanda. Methods: A cross-sectional study was carried out among 420 participants (hypertensive and non-hypertensive) at the University Teaching Hospital of Kigali (CHUK) and Ruhengeri Hospital in Rwanda. Periodontitis was assessed using clinical parameters: clinical attachment loss (CAL), bleeding on probing (BoP), and periodontal pocket depth (PDD). Hypertension was defined as a patient with a systolic or diastolic blood pressure (SBP/DBP) of ≥140/90 mmHg. Descriptive statistics, the Chi-square test, and logistical regression were performed using SPSS version 29 for statistical data analysis. Results: The prevalence of periodontitis was found to be 69.5% among hypertensive patients and 52.4% among non-hypertensive patients. Clinical attachment loss was 6.24 times (AOR = 6.24, 95% CI: 1.99-19.56) higher among hypertensive patients and the difference was significant (p = 0.001). Other periodontal parameters such as periodontal pocket depth and bleeding on probing showed a more significant association among hypertensive than non-hypertensive patients. Conclusions: Our study found a significant association between periodontitis and hypertension in Rwandan adults. However, further intervention studies are needed to explore causality and potential interventions.
RESUMO
AIM: To (i) assess the prevalence, incidence, and burden of severe periodontitis and edentulism in 2021, and (ii) forecast their rates in 2050. METHODS: Prevalence, incidence, and Years Lived with Disability (YLDs) for severe periodontitis and edentulism in 2021 were gathered globally, covering 204 countries, seven super regions, and 21 regions from the Global Burden of Disease (GBD) 2021 study. Prevalence, incidence, and YLDs due to periodontitis and edentulism to 2050 were projected using mixed-effects models with the socio-demographic index as the main covariate. RESULTS: In 2021, over 1 billion people were affected by severe periodontitis (1066.95 million; 95% UI: 896.55-1234.84), with a global age-standardized prevalence of 12.50% (10.53-14.49). South Asia had the highest prevalence rate, at 17.57% (14.73; 20.14). Edentulism affected 353 million people globally (300.60-416.20), resulting in an age-standardized prevalence of 4.11% (3.50; 4.83). The highest edentulism prevalence was found in Latin America and the Caribbean, at 7.39% (6.44; 8.39). By 2050, more than 1.5 billion people (+44.32%) are projected to have severe periodontitis, and over 660 million (+84.40%) to be edentulous. In the same year, 19.67% (130.23 million) of the edentulous people worldwide will be located in China. Severe periodontitis is expected to move up one position, and edentulism nine positions, among the most impactful Level 4 diseases/conditions affecting YLDs worldwide by 2050. CONCLUSION: Severe periodontitis and edentulism remain major public health challenges in 2021, with the number of affected individuals projected to rise significantly in the coming decades.
RESUMO
The oral microbiome is a diverse and complex ecosystem essential for maintaining oral and systemic health. Our study is the first to define the oral microbial community in Egyptian young adults and investigate the effects of natural antimicrobials on the oral microbiome. SuperMint (SM) is a proprietary blend of peppermint, Japanese mint, bergamot mint, and spearmint essential oils encapsulated in a tiny soft beadlet. This work aimed to evaluate the effects of SM beadlets on the oral microbiome. This study recruited twenty healthy participants. A baseline investigation of the oral microbiome of the selected participants was performed by collecting saliva and swab samples before treatment. Treatment included chewing four SM beadlets twice a day for 7 days, and then, post-administration saliva and swab samples were collected at the end of treatment. The oral microbiome samples were analyzed by the high-throughput amplicon sequencing of 16S rRNA gene fragments, and the community composition was determined. The results showed that the abundance of some microbial genera and families decreased after using SM, including Prevotella, Streptococcus, Neisseria, and Haemophilus. However, some genera showed inconsistent patterns. We also found that the subject's gender and SM usage were significantly associated with diverse microbial composition. The results suggest that SM treatment decreased the abundance of several bacteria associated with halitosis and periodontal diseases, such as Actinomyces and Streptococcus. Furthermore, Corynebacterium species increased and Streptococcus decreased after SM usage. More research is needed to fully understand the antimicrobial effects of mint oils and their potential applications in maintaining good oral health.
RESUMO
OBJECTIVES: Oral diseases are among the most prevalent diseases globally. Accumulating new evidence suggests considerable benefits of epigallocatechin-3-gallate (EGCG) for oral health. This review aims to explore the role and application of EGCG in main oral diseases. METHODS: This narrative review thoroughly examines and summarizes the most recent literature available in scientific databases (PubMed, Web of Science, Scopus, and Google Scholar) reporting advances in the role and application of EGCG within the dental field. The major keywords used included "EGCG", "green tea extract", "oral health", "caries", "pulpitis", "periapical disease", "periodontal disease", "oral mucosa", "salivary gland", and "oral cancer". CONCLUSIONS: EGCG prevents and manages various oral diseases through its antibacterial, anti-inflammatory, antioxidant, and antitumor properties. Compared to traditional treatments, EGCG generally exhibits lower tissue irritation and positive synergistic effects when combined with other therapies. Novel delivery systems or chemical modifications can significantly enhance EGCG's bioavailability, prolong its action, and reduce toxicity, which are current hotspots in developing new materials. CLINICAL SIGNIFICANCE: this review provides an exhaustive overview of the biological activities of EGCG to major oral diseases, alongside an exploration of applications and limitations, which serves as a reference for preventing and managing oral ailments.
RESUMO
Human beta-defensins are host defense peptides with broad antimicrobial and inflammatory functions. In the oral cavity, these peptides are produced mainly by the keratinocytes of the epithelium; however, fibroblasts, monocytes, and macrophages also contribute to oral human beta-defensin expressions. The resident and immune cells of the oral cavity come into contact with various microbe-associated molecular patterns continuously and simultaneously. The overall antimicrobial cellular response is highly influenced by local and environmental factors. Recent studies have produced evidence showing that not only systemic chronic diseases but also systemic factors like hyperglycemia, pregnancy, the long-term use of certain vitamins, and aging can modulate oral cellular antimicrobial responses against microbial challenges. Therefore, the aim of this narrative review is to discuss the role of systemic factors on oral human beta-defensin expressions.
RESUMO
BACKGROUND: The aim of this meta-analysis was to evaluate the role of a history of periodontitis on implant failure. The two main judgment criteria studied are peri-implantitis and the survival rate. The two secondary judgment criteria studied are the mean pocket depth and the mean peri-implant bone loss. METHODS: An electronic search was performed via five databases (MEDLINE, Embase, ScienceDirect, LILACS and the Cochrane Library) and was supplemented by manual searching. The search was undertaken in June 2024. RESULTS: Of 10 775 potentially eligible articles, 8 were included in the qualitative analysis and 10 in the quantitative synthesis. CONCLUSIONS: This meta-analysis suggests that a history of periodontitis has a significant impact on the rate of peri-implantitis, survival rate, mean bone loss and pocket depth.
