Association Between Oral Health Status and Oral Health-Related Quality of Life in Individuals With Thyroid Dysfunction: A Cross-Sectional Study.

Background and aim Any alterations in the hormonal regulation system such as thyroid dysfunction may have an impact on oral health status, which in turn may affect their oral health-related quality of life (OHRQoL). The objective of this study was to determine the association of thyroid dysfunction on oral health status and OHRQoL of subjects with thyroid dysfunction. Materials and methods A cross-sectional study was conducted among 150 subjects with thyroid dysfunction and 150 subjects without thyroid dysfunction aged 18-60 years from a government hospital in Bangalore city. Subjects with or without thyroid dysfunction aged 18-60 years were included in the study. Subjects who had other systemic conditions, who were pregnant or lactating, who had tobacco chewing or smoking habits, and who had undergone periodontal therapy in the past six months were excluded. OHRQoL was assessed using a pre-validated Oral Health Impact Profile-14 (OHIP-14) questionnaire. Oral health examination was done using the WHO Oral Health Assessment Form for Adults, 2013. Descriptive and inferential statistics were performed. Results The mean age of the subjects with and without thyroid dysfunction was 43.01±10.9 and 42±9.8, respectively, with female predominance. Most of them had a socioeconomic status of less than the lower middle class. Subjects with thyroid dysfunction showed a higher proportion of dental caries, root caries, gingival bleeding, periodontal pocket, and loss of attachment as compared to the subjects without thyroid dysfunction (p<0.05).Subjects with hyperthyroidism showed poor periodontal condition and a higher proportion of dental caries experience as compared to subjects with hypothyroidism (p>0.05). Oral health indicators showed a significant positive correlation with OHRQoL among subjects with or without thyroid dysfunction. Conclusion There was an association between oral health status and OHRQoL among subjects with thyroid dysfunction when compared to subjects without thyroid dysfunction. Therefore, it is necessary to inform individuals with thyroid dysfunction about the importance of preventive oral care.

AI-based prediction and classification of root caries using radiographic images.

Root surface caries, commonly known as root decay, is a common dental disorder that affects tooth roots. Like enamel-based tooth decay, root caries attack exposed root surfaces caused by gum recession or periodontal disease. Older persons with gum recession, tooth loss, or poor oral hygiene may be more likely to develop this disorder. Dental root caries must be diagnosed early to improve treatment and prevention. This research will examine radiographic image-based AI-based root caries prediction algorithms. Saveetha Dental College supplied 200 root surface radiographs. An expert dentist and dental radiologist confirmed one hundred teeth with root caries and 100 without. Edited and segmented radiographic images. Orange, a machine learning squeeze net embedding model with Naive Bayes, Logistic Regression, and neural networks, was used to assess prediction accuracy. Training and test data were split 80/20. Cross-validation, confusion matrix, and ROC analysis assessed model performance. This study examined precision and recall. Naïve bayes and logistic regression have 96% and 100% accuracy, but class accuracy is -94% and 100% in image classification of root caries was seen. AI-based root caries prediction utilizing radiographic images would improve dental care by diagnosing and treating early, accurately, and personalized. With appropriate deployment, research, and ethics, AI integration in dentistry could benefit practitioners and patients. Dental professionals and AI experts must work together to maximize this new technology.AI integration in dentistry can significantly improve root caries diagnosis and treatment by predicting root caries using radiographic images. This early detection reduces treatment need and time. Collaboration between dental professionals and AI experts is crucial for maximizing benefits.

Topical Effect of Silver Diamine Fluoride in Preventing and Arresting Root Caries in Elderly Patients.

Aim of the study: The purpose of the present investigation was to see how efficient silver diamine fluoride (SDF) solution treatment to prevent dental root caries.&#x0D; Materials and method: This research was done at Iraq's geriatric facilities. Forty seniors with active caries lesions were fortuitously assigned into two groups: Group 1 (placebo control)—doubles Twice-Annual treatment with soda water; Group 2—Doubles Twice-Annual treatment with silver diamine fluoride solution.&#x0D; Results: After 18 months, the arrest rates of root caries were 28 percent in group1 (control) and 88 percent group 2 silver diamine fluoride solutions (x2 test, p &lt; 0.05). There was a considerable relation (dependent) between silver diamine fluoride and stopping root surface dental caries Chi=7.08, df=2, P&lt;0.05, which means that silver diamine fluoride was efficient in stopping dental caries while there was no relation (independent) between placebo dye and arresting caries, Chi=1.33 df=2 P&gt;0.05.&#x0D; Conclusions: Silver diamine fluoride solution was helpful in avoiding root caries in elderly people who do not have access to fluoridated water.

Dental Caries a Risk Factor for Intracerebral Hemorrhage

Introduction: Streptococcus mutans is a known cause of dental caries that contains a collagen-binding protein, Cnm, and exhibits inhibition of platelet aggregation and matrix metalloproteinase-9 activation. This strain has been linked to aggravation of experimental intracerebral hemorrhage (ICH) and may be a risk factor for ICH. The purpose of this study was to test the association between dental caries and incident ICH. Methods: The presence of dental caries and periodontal disease was assessed in subjects from the Dental Atherosclerosis Risk in Communities (DARIC) study without prior stroke or ICH. This cohort was followed for incident ICH over a period of 10 years. Cox regression was used to compute crude and adjusted hazards ratio from the dental assessment. Results: Among 6,315 subjects, dental surface caries and/or root caries were recorded in 1,338 (27%) subjects. Of those, 7 (0.5%) had incident ICH over a period of 10 years following the visit 4 assessment. Of the remaining 4,977 subjects, 10 (0.2%) had incident ICH. Those with dental caries versus those without dental caries were slightly younger (mean age 62.0 ± 5.7 vs. 62.4 ± 5.6, p = 0.012), had a greater proportion of males (51 vs. 44%, p < 0.001), African Americans (44 vs. 10%, p < 0.001), and were hypertensive (42 vs. 31%, p < 0.001). The association between caries and ICH was significant (crude HR 2.69, 95% CI 1.02–7.06) and strengthened after adjustment for age, gender, race, education level, hypertension, and periodontal disease (adjusted HR 3.88, 95% CI 1.34–11.24). Conclusion: Dental caries is a potential risk for incident ICH after caries detection. Future studies are needed to determine if treatment of dental caries can reduce the risk of ICH.

Historical background and clinical implications of silver diamine fluoride in dentistry: A narrative review

Dental caries is a chronic, irreversible disease affecting preschool children worldwide. As the frequency of dental caries has steadily declined over the past few years, children from low socioeconomic backgrounds still have higher rates of dental caries, and still have a higher prevalence in developing countries. Though the role of fluoride in dental caries prevention has been scientifically proven, the antimicrobial effect of silver compounds to treat various infections has been postulated. However, 38% silver diamine fluoride (SDF) solution is currently used to arrest dental caries, and as an antihypersensitivity agent. The SDF solution is available in dark, amber-colored bottles and is simple, non-invasive, and easy to use by trained dentists or specialists. Although it has the disadvantage of causing black discoloration and an unpleasant metallic taste after application, studies in the literature show that it can help prevent dental caries, hypersensitivity, root caries, and remineralization. This article explains in depth the SDF: its historical background, clinical application, and efficacy in different fields of dentistry.

A Systematic Review on Caries Status of Older Adults

The aim of this systematic review was to provide an update on caries prevalence in older adults aged 60 years or above around the globe. Two independent reviewers performed a systematic literature search of English publications from January 2016 to December 2020 using Pubmed, Scopus, Embase/Ovid and Web of Science. The MeSH terms used were “dental caries”, “root caries”, “DMF index”, “aged” and “aged 80 and over”. Further searches in Google Scholar retrieved eight additional publications. The epidemiological surveys reporting the prevalence of dental caries or root caries or caries experience using DMFT (decayed, missing and filled teeth) and DFR (decayed and filled root) in older adults aged 60 years or above were included. Quality of the publications was assessed using the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data. Among the 5271 identified publications, 39 articles of moderate or good quality were included. Twenty studies were conducted in Asia (China, India, Vietnam, Singapore and Turkey), ten in Europe (Ireland, Norway, Finland, Germany, Portugal, Poland, Romania and Kosovo), three in North America (USA and Mexico), one in South America (Brazil), two in Oceania (Australia) and three in Africa (Malawi, Egypt and South Africa). The prevalence of dental caries ranged from 25% (Australia) to 99% (South Africa), while the prevalence of root caries ranged from 8% (Finland) to 74% (Brazil) in community dwellers. The situation was even worse in institutionalised older adults of which the mean DMFT score varied from 6.9 (Malawi) to 29.7 (South Africa). Based on the included studies published in the last 5 years, caries is still prevalent in older adults worldwide and their prevalence varies across countries.

Quantitative and Qualitative Analysis of Dental Caries among Different Age Groups of Patients in a Private Dental College Hospital, Chennai, India

Dental caries is the major health disorder caused by the interaction of oral microbes on the dental hard tissues.Dental caries are multifactorial in nature of etiology and pathogenesis. According to WHO almost 36% ofthe population have dental caries. Thus the aim of the current study is to quantitatively and qualitativelyanalyse the prevalence of dental caries among different age groups of patients visiting Saveetha dentalcollege and hospital outpatient department services. All the cases reported between the month of June2019 to March 2020 for dental caries of different classes were chosen for this study. Data of patients wereretrieved from dental records. Data of patients with class I to class VI dental caries and root caries wereincluded and age, gender, tooth affected were analyzed, tabulated and was subjected to statistical analysis.From the data analysis through SPSS it is observed that, the overall incidence of dental caries were higheramong male patients (54.7%), between the age group of 15 to 30 years (45.4%) and was commonly seen inprimary and permanent posterior tooth.(72.6%). Within the limitations of the present study, dental caries hadmale predilection, predominantly between the age group of 15 to 30 years,Class 1 caries primarily reportedin the molars.

Epidemiology of dental root caries: a review of risk factors

: Root surface caries is a common disease among the older adults worldwide. This paper reports on two recent systematic reviews which were conducted to identify the risk factors of root caries, one on risk indicators and one on risk predictors, and to describe their relationship with the prevalence and incidence of root caries. Articles in four electronic databases (PubMed, MEDLINE, EMBASE, and Scopus) published in 1990 to 2018 were searched. Epidemiological studies conducted on general populations and investigated at least one risk factor of root caries were included. Relevant information was extracted by two reviewers independently. The factors were put into five main categories, namely demographic and social background, health behaviors, general health, oral health habits and oral health conditions. Forty cross-sectional surveys (78,183 participants in total) and 16 longitudinal cohort studies (7,340 participants in total) from different countries worldwide were included in the reviews. There were positive correlations between dental root caries and age, past root caries experience, exposure of root surfaces and use of tobacco. Negative correlations with socio-economic status and oral hygiene were found. Higher risk of having or developing new root caries were found among the older adults, people with lower socio-economic status, tobacco users, and those with greater root caries experience, more gingival recession and more dental plaque.

Factors Associated with Dental Root Caries: A Systematic Review.

The objectives of this review were to identify the factors associated with root caries and to describe their relationship with the presence and extent of root caries. A search was carried out on the PubMed, Medline, Embase, and Scopus databases for articles published between January 1990 and October 2018. Information was extracted on the factors associated with the presence or extent of decayed or filled root surfaces and/or decayed root surfaces. Factors were sorted into 6 categories: social-demographic background, general health, health behaviors, fluoride exposure, oral health habits, and oral health condition. The quality of the 127 identified relevant papers was assessed, and those of low methodological quality were excluded. Finally, 44 articles reporting on 40 cross-sectional studies were included. The total sample size comprised 78,183 participants from different countries around the world. Positive correlations were detected between root caries and age, gingival recession, and use of tobacco, while negative correlations were found for social position, use of fluoride toothpaste, and oral hygiene status. Mixed findings were reported for association with the number of teeth and dental visit behaviors. This systematic review found a number of factors in different categories to be associated with root caries. People who are older, of lower socioeconomic status, or tobacco users and those with more gingival recession and poorer oral hygiene have higher risk of root caries. This systematic review found a number of factors associated with root caries, including age, social position, exposure to fluoride, and oral hygiene status. This information helps dental public health workers and clinicians identify the groups at high risk of caries and the factors to act on for more effective prevention and management of root caries (e.g., use fluoride toothpaste and improve oral hygiene).

Voriconazole inhibits cross-kingdom interactions between Candida albicans and Actinomyces viscosus through the ergosterol pathway

Candida albicans and Actinomyces viscosus are prominent microbes associated with dental root caries. The aim of this study was to investigate the effect of C. albicans on A. viscosus biofilms and to identify the mechanisms associated with this interaction. A. viscosus and C. albicans strains (wide-type and mutants) were used to form biofilms in vitro and in vivo, which were subsequently analysed by crystal violet assay and scanning electron microscopy (SEM) to investigate the effect of C. albicans on A. viscosus growth. A viable plate count and survival curve for C. albicans mutants and A. viscosus combinations were used to identify which C. albicans pathway was crucial for cross-kingdom interactions. Voriconazole was used to block their interactions both in vitro and in vivo. SEM, fluorescence in situ hybridisation (FISH), quantitative PCR and survival curve analyses were performed to evaluate the activity of voriconazole on C. albicans and A. viscosus interactions. The biomass and virulence of mixed-species biofilms were significantly enhanced compared with the A. viscosus biofilm alone. However, this was not observed in the mixed-species biofilms with the C. albicans mutant erg11Δ/Δ in vitro and in vivo, indicating that azoles may work on the mixed-species biofilms. As expected, voriconazole can effectively reduce the biomass of mixed-species biofilms. A high concentration of voriconazole (1 µg/mL) reduced the abundance of C. albicans, whilst a low voriconazole concentration (0.25 µg/mL) blocked their interactions similar to the effect of the erg11Δ/Δ mutant. Voriconazole may be a candidate strategy to combat root caries pathogens.

Active oxygen in the treatment of (root) caries and its suitability for frail older people

In 2000 it was suggested that there was a new, fast and simple way to treat dental caries based on the outcomes of an in vitro study of the antimicrobial effect of ozone, a form of active oxygen, on caries lesions in dental roots. The aim of the review of literature described in this article was to determine the effectiveness of active oxygen in the treatment of dental (root) caries as demonstrated by in vivo research of frail older people'. From the results it became clear that the quality of the various trials is not very high and that there is, at least at the present time, an insufficient solid scientific evidence base that the use of ozone is an effective treatment for dental (root) caries. It is, however, still too early to conclude that active oxygen, in whatever form, cannot contribute positively to the fight against caries.

10-year experience of dental root caries treatment in patients with gingival recession

Based on the analysis of our own clinical experience, a concept of approaches to planning diagnostic, preventive and curative measures for patients with dental root caries and gingival recession was developed. The aim of the research. To provide a rationale for the developed concept of approaches to planning diagnostic, preventive and curative measures for patients with dental root caries and gingival recession. Objects and methods. Dental examination and treatment of more than 1082 subjects with dental root caries and gingival recession was performed. Registration and objective assessment of clinical condition were carried out based on the analysis of a survey data, clinical examination data and a series of objective parameters. Control examinations were carried out every 3 to 6 months. The effectiveness of diagnostic, preventive and curative measures was assessed according to good, satisfactory and unsatisfactory results achieved. Results and discussion. A complex of methods for diagnosis and treatment of root caries in patients with gingival recession was developed, which made it possible to propose and designate a new classification and treatment method for this group of patients. Conclusion. Feasibility of the developed concept for planning a diagnostic, preventive and curative measures in patients with dental root caries and gingival recession is supported by good therapeutic results achieved in 97.7% of patient in short-term follow-up period, and by consistency of these results in long-term observation period in 96.3% of patients, thus providing a rationale for application of the proposed concept in practical health care.

Oral manifestations of type 2 diabetes mellitus of Bhopal city: an observational prospective study

Introduction: Type 2 diabetes mellitus involves a variety of dysfunctions bringing about a few delicate tissue variations from the norm in the oral cavity. These incorporate gingivitis periodontitis, salivary dysfunction, taste dysfunction, oral fungal and bacterial infections, geographic tongue, benign migratory glossitis, fissured tongue, traumatic ulcer, lichen planus, angular cheilitis, delayed mucosal healing, dental root caries, tooth loss, mucosal neurosensory disorders, and oral mucosal lesions. Aim and objectives: This study aims to determine the frequency of different oral manifestations in patients of Type 2 Diabetes Mellitus of Bhopal city which will expand the consciousness of oral signs of diabetes mellitus subsequently helping in speeding up the examination regarding this matter. Methodology: This descriptive study was carried out at the Department of Medicine, People’s Hospital, hitech division, Bhopal from March 2016 to January 2017. 200 patients satisfying the inclusion criteria (diagnosed cases of type 2 diabetes mellitus of > 35 years of age) were included in the study. 84 (42%) were female and 116(58%) were male patients. Result: The frequency of different oral manifestations seen in female diabetic patients in descending order were; gingivitis (49%), periodontitis (36.7%), dental root caries (20%), taste dysfunction (8%), burning mouth syndrome (8%), xerostomia (31%), recurrent apthous stomatitis (11%) and oral candidiasis (2%) and in male diabetic patients in descending order were; gingivitis (41%), periodontitis (29%), dental root caries (18%), taste dysfunction (9%), burning mouth syndrome (3%), xerostomia (31%), recurrent apthous stomatitis (5%) and oral candidiasis (3%). Conclusion: It was inferred that diabetic patients are more inclined to get oral complications so health education, timely diagnosis and effective treatment should be carried out to prevent these complications.

New Preventive Approaches Part II: Role of Dentin Biomodifiers in Caries Progression.

Dental caries is the most prevalent infectious chronic disease in children and adults. With a globally aging population, new demands in the management of dental caries are awakened by the rampant increase in the incidence of dental root caries. Like crown caries, root caries requires bacterial driven tissue demineralization followed by the degradation of the extracellular dentin matrix. Due to the complex composition and ultrastructure, preventive strategies targeting the mineral phase of dentin are insufficient for managing the prevention and progression of root caries. However, the composition and ultrastructure of dentin has inspired novel strategies for the effective management of highly susceptible root surfaces. Specifically, the complex and dynamic dentin extracellular matrix (ECM). The ECM of mature dentin contains a robust type I collagen fibrils scaffold, and carefully distributed non-collagenous components, such as proteoglycans, phosphoproteins, and proteases. In this chapter, we will review the experimental strategies of potential clinical impact to prevent root caries progression by site modifications of the mature extracellular dentin matrix. This approach, termed dentin biomodification, encompasses bioinspired strategies to locally enhance the biological and biomechanical characteristics of the tissue by mimicking natural processes. Here, synthetic and biosynthetic compounds can decrease the biodegradability of the dentin ECM and provide mechanical enhancement of dentin. The resulting effect is the maintenance of the dentin ECM to halt root caries progression and possibly mediate effective remineralization of the caries affected root dentin.

Randomized clinical trial on arresting dental root caries through silver diamine fluoride applications in community-dwelling elders.

The immediate application of potassium iodide to dental root caries treated with silver diamine fluoride improved the colour of the lesion from black to bright yellow, but this colour change was only short lived.

Randomized Clinical Trial on Preventing Root Caries among Community-Dwelling Elders.

Dental root caries is a common disease among elders. More efforts on preventing this disease are needed. Silver diammine fluoride (SDF) is known to prevent dental caries in primary teeth. However, clinical evidence of its efficacy in preventing root surface caries is limited. This clinical trial aimed to compare the effectiveness of SDF in preventing root caries among elders in a water fluoridated area. A total of 323 elders who had at least 5 teeth with exposed root surfaces and who had self-care ability were randomly allocated into 3 intervention groups: group 1 (placebo control), annual application of tonic water; group 2, annual application of SDF solution; group 3, annual application of SDF solution, immediately followed by potassium iodide (KI) solution. Oral hygiene instructions and fluoride toothpaste were provided to all subjects. Status of dental root surface was assessed every 6 mo by the same independent examiner. After 30 mo, 257 (79.6%) elders were reviewed. The mean numbers of root surface with new caries experience in the control, SDF, and SDF/KI groups were 1.1, 0.4, and 0.5, respectively (analysis of variance, P < 0.001). Scheffe's multiple comparison showed that elders who received placebo developed more new root caries lesions ( P < 0.05), while the difference between the SDF and SDF/KI groups was not statistically significant ( P > 0.05). Moreover, elders who had higher visible plaque index scores at 30-mo examination (analysis of covariance, P < 0.001) and those who had higher baseline DMFT scores (analysis of covariance, P = 0.005) developed more new root caries. It is concluded that annual application of SDF or SDF/KI solution is effective in preventing root caries among community-dwelling elders in a fluoridated area ( ClinicalTrials.gov NCT02360124). Knowledge Transfer Statement: Annual topical application of silver diammine fluoride or silver diammine fluoride / potassium iodide solution is effective in preventing dental root surface caries among community-dwelling elders in a fluoridated area.

Randomized clinical trial on arresting dental root caries through silver diammine fluoride applications in community-dwelling elders

ObjectivesTo investigate the effectiveness of silver diammine fluoride (SDF) solution application in arresting dental root caries and to assess the color of arrested caries lesions. MethodsThis study was conducted in elderly centers in Hong Kong. A total of 83 elders with 157 root surfaces with active caries lesion were randomly allocated into 3 groups: Gp1 (placebo control)—annual application of soda water; Gp2–annual application of SDF solution; Gp3–annual application of SDF solution immediately followed by potassium iodide (KI) solution. Color of the arrested root caries lesion was assessed with reference to PANTONE color plates and classified into one of the followings: yellow (7401U); light brown (1245U); dark brown (4635U); and black (Black U). Status of root surfaces was assessed every 6 months by the same independent examiner. ResultsAfter 30 months, 100 (64%) of the included root caries lesions were reviewed. The arrest rates of root caries were 45%, 90%, and 93% in Gp1 (control), Gp2 (SDF) and Gp3 (SDF/KI), respectively (χ2 test, p<0.001). Pairwise comparisons showed elders in the control group had a lower proportion of the active root caries changed to arrested (p<0.001) and the proportions of root caries being arrested in the SDF and SDF/KI groups were not significantly different (p>0.05). The distributions of arrested caries lesions by color were not significantly different between the SDF and SDF/KI groups (χ2 test, p>0.05). ConclusionsApplication of SDF solution, with or without application of KI afterwards, is effective in arresting root caries among elders in a water fluoridated area. In the long term, blackening of arrested root caries is not reduced by immediate application of KI after the application of SDF. Clinical significanceIn a water fluoridated area, annual application of SDF solution or SDF/KI solution can arrest dental root caries in elders. In the long term, application of KI does not reduce the blackening of arrested caries lesions caused by SDF.

Oral health status of institutionalized elderly in Korea

Purpose: The institutionalized elderly have placed the most vulnerable state, and the report about the oral health status of the institutionalized elderly was scarce. The aims of the current study were to investigate the oral health status of institutionalized elderly. Materials and methods: The survey of the oral health status was carried out on 487 institutionalized elderly from 4 longterm care facilities of Seoul metropolitan city, Gyunggi province, and Gangwon province in Korea. Results: The prevalence of dental caries, root caries, and dental calculus of the institutionalized elderly was 19.2%, 15.3%, and 23.7%, respectively. The percentage of edentulism among the institutionalized elderly was 26.2%. Those who had poor oral hygiene and tongue coating were 43.9% and 90.5%, respectively. The percentages wearing complete and removable partial denture on maxilla were 12.8% and 3.3%, respectively. The percentages wearing complete and removable partial denture on mandible were 7.8% and 5.6%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on maxilla were 29.7% and 27.2%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on mandible were 24.5% and 30.9%, respectively. Conclusion: The oral health stuatus of institutionalized elderly was poor. For the oral health promotion of elderly in longterm care facilities, it is essential to educate nurses and caregivers about the importance of the oral health and oral hygiene method.
