Objective: To identify the prevalence of caries, plaque score, and periodontal disease and explore the correlations between oral health literacy scores and oral health status among undergraduate students. Materials and Methods: A cross-sectional study was conducted with a group of undergraduate students using the Malay version of the Oral Health Literacy (OHL) Index. A stratified random sampling technique was used to select the samples. Clinical oral examinations were conducted by a single trained examiner using a Community Periodontal Index (CPI) probe and a mouth mirror. Data analysis was conducted using statistical tests contained in SPSS version 26, and statistical significance was set at p<0.05. Results: A total of 280 students were recruited into the study. The prevalence of caries and periodontal disease was 58.9 and 13.2%, respectively. There was a significant association between OHL and field of study (p<0.001). There was also a significant negative but weak correlation between OHL and dental plaque scores (r= -0.147; p=0.014). A significant positive but weak correlation was found between dental plaque scores and dental caries (r= 0.135; p=0.024) and periodontal pocket depth (r= 0.168; p=0.005). Conclusion: The prevalence of dental caries was high, while the prevalence of periodontal diseases was low in this study. OHL correlated significantly with dental plaque scores and field of the study. Thus, OHL assessment is essential to understand a person’s OHL levels and can be considered a screening tool for early detection of poor oral hygiene.

Complex Scenario

Dental plaque is still considered the main etiological factor for periodontal diseases. Our understanding of periodontal disease has advanced from the previous concepts where gingivitis slowly progressed to periodontitis to a more complex scenario that correlates several risk factors in the pathogenesis of periodontal disease. Among these factors, age has been associated with increased rates of periodontal disease as the population gets older. Although the loss of alveolar bone and periodontal attachment is common in the elderly population, and there is evident age-related changes in the periodontium, severe periodontitis is not a natural consequence of ageing. The importance of identifying the risk factors that participate in the pathogenesis of periodontal disease at an early phase, both of the individual and the disease, as well as evaluating the capacity of the individual to control dental plaque will enable the implementation of an adequate preventive program, where the needs and limitations of the individual are considered to specifically tailor the oral hygiene procedures and the mouthwashes to be used.

The dental plaque is an oral microbiome hardly associated to be the etiological agent of dental caries and periodontal disease which are still considered serious health public problems. Silver nanoparticles (AgNPs) have demonstrated to have good antimicrobial properties affecting a wide variety of microorganisms, including oral bacteria; however, there is no scientific information that has evaluated the antimicrobial effect of AgNPs against clinical oral biofilms associated with dental caries and periodontal disease. The aim of this study was to determine the antimicrobial and substantivity effects of AgNPs in oral biofilms isolated clinically from patients with dental caries and periodontal disease. Sixty-seven young and young-adult subjects with dental caries and periodontal disease were clinically sampled through the collection of subgingival dental plaque. The inhibitory effect of AgNPs was performed with standard microbiological assays by triplicate using two sizes of particle. Polymerase chain reaction (PCR) assay was used to identify the presence of specific bacterial species. All AgNPs showed an inhibitory effect for all oral biofilms for any age and, generally, any gender (p>0.05); however, the effectiveness of the antimicrobial and substantivity effects was related to particle size, time, and gender (p<0.05). The identified microorganisms were S. mutans, S. sobrinus, S. sanguinis, S. gordonii, S. oralis, P. gingivalis, T. forsythia, and P. intermedia. The AgNPs could be considered as a potential antimicrobial agent for the control and prevention of dental caries and periodontal disease.

INTRODUCTION: Periodontal disease is an inflammatory response to bacteria that reside in the gum tissue and can have systemic repercussion. OBJECTIVE: The aim of this study was to assess the relationship between periodontitis and markers of cardiovascular risk. MATERIAL AND METHOD: Ninety selected patients were assigned into two groups in accordance with their levels of probing pocket depth (PPD) and Clinical Attachment Level (CAL): control group, n= 45 (< 4 sites with PPD ≥ 4.0 mm and CAL ≥ 3.0 mm) and case group, n= 45 (≥ 30% of sites with PPD ≥ 4.0 mm and CAL ≥3.0 mm). Plasma concentrations of C-reactive protein, high sensitive CRP, high-density lipoproteins (HDL-c) and electronegative low density lipoproteins (LDL) were assessed in all participants. Data from medical history and socioeconomic level were also collected from patients. RESULT: Plasma levels of HDL-c were lower in subjects with periodontal disease (p = 0.016) and were inversely associated with the number of sites with PPD ≥ 3 mm (rho= -0.325) and number of sites with PPD ≥ 3 mm and CAL ≥ 3 mm (rho= -0.216). These associations remained significant after adjustments for dental plaque and smoking using Univariate Analysis of Covariance (p < 0.05). Adjusted odds ratio between periodontal disease and levels of HDL-c was 0.94 (CI95% 0.88-0.99) after adjusting for age, smoking and dental plaque. Other investigated markers of cardiovascular risk were not related to periodontal disease. CONCLUSION: Clinical parameters of periodontitis were inversely associated with plasma concentrations of HDL-c.

ABSTRACTTannerella forsythiaandFusobacterium nucleatumare dental plaque bacteria implicated in the development of periodontitis. These two species have been shown to form synergistic biofilms and have been found to be closely associated in dental plaque biofilms. A number of genetic loci for TonB-dependent membrane receptors (TDR) for glycan acquisition, with many existing in association with genes coding for enzymes involved in the breakdown of complex glycans, have been identified inT. forsythia. In this study, we focused on a locus, BFO_0186-BFO_0188, that codes for a predicted TDR-SusD transporter along with a putative β-glucan hydrolyzing enzyme (BFO_0186). This operon is located immediately downstream of a 2-gene operon that codes for a putative stress-responsive extracytoplasmic function (ECF) sigma factor and an anti-sigma factor. Here, we show that BFO_0186 expresses a β-glucanase that cleaves glucans with β-1,6 and β-1,3 linkages. Furthermore, the BFO_0186-BFO_0188 locus is upregulated, with an induction of β-glucanase activity, in cobiofilms ofT. forsythiaandF. nucleatum. The β-glucanase activity in mixed biofilms in turn leads to an enhanced hydrolysis of β-glucans and release of glucose monomers and oligomers as nutrients forF. nucleatum. In summary, our study highlights the role ofT. forsythiaβ-glucanase expressed by the asaccharolytic oral bacteriumT. forsythiain the development ofT. forsythia-F. nucleatummixed species biofilms, and suggest that dietary β-glucans might contribute in plaque development and periodontal disease pathogenesis.IMPORTANCEThe development of dental plaque biofilm is a complex process in which metabolic, chemical and physical interactions between bacteria take a central role. Previous studies have shown that the dental pathogensT. forsythiaandF. nucleatumform synergistic biofilms and are closely associated in human dental plaque. In this study, we show that β-glucanase from the periodontal pathogenT. forsythiaplays a role in the formation ofT. forsythia-F. nucleatumcobiofilms by hydrolyzing β-glucans to glucose as a nutrient. We also unveiled that the expression ofT. forsythiaβ-glucanase is induced in response toF. nucleatumsensing. This study highlights the involvement of β-glucanase activity in the development ofT. forsythia-F. nucleatumbiofilms and suggests that intake of dietary β-glucans might be a contributing risk factor in plaque development and periodontal disease pathogenesis.

Dental plaque, a natural oral biofilm is involved in the aetiology of dental caries and periodontal disease. Despite decades of research, the microbiology, aetiology and pathogenesis of these diseases remain controversial. A number of factors interplay in these diseases, the indigenous microbes that inhabit the oral cavity, diet, host susceptibility and time. The ?Non-Specific Plaque Hypothesis? (NSPH) was proposed where the overall mass of plaque interacted with the host and caused disease. An alternative view was the ?Specific Plaque Hypothesis? (SPH) where, among the diverse microbial community, a limited subset of specific bacteria were associated with disease. In recent years, the ?Ecological Plaque Hypothesis? (EPH) has been proposed that it be recognised that the oral ecology as a whole contributes to the aetiology of dental caries and periodontal diseases, with shifts in the composition of microbial communities being of particular importance.
