Metagenomic Characterization and Comparative Analysis of Removable Denture-Wearing and Non-Denture-Wearing Individuals in Healthy and Diseased Periodontal Conditions.

Removable denture wearers are at an increased risk of developing periodontal diseases due to biofilm deposition and microbial colonization on the denture surface. This study aimed to characterize and compare the metagenomic composition of saliva in denture wearers with different periodontal statuses. Twenty-four community-dwelling elders were recruited and grouped into denture wearers with active periodontitis (APD), non-denture wearers with active periodontitis (APXD), denture wearers with stable periodontal health conditions (SPCD), and non-denture wearers with stable periodontal health conditions (SPCXD). Saliva samples were collected and underwent Type IIB restriction-site-associated DNA for microbiome (2bRAD-M) metagenomic sequencing to characterize the species-resolved microbial composition. Alpha diversity analysis based on the Shannon index revealed no significant difference between groups. Beta diversity analysis using the Jaccard distance matrix was nearly significantly different between denture-wearing and non-denture-wearing groups (p = 0.075). Some respiratory pathogens, including Streptococcus agalactiae and Streptococcus pneumoniae, were detected as the top 30 species in saliva samples. Additionally, LEfSe analysis revealed a substantial presence of pathogenic bacteria in denture groups. In the cohort of saliva samples collected from community-dwelling elders, a remarkable abundance of certain opportunistic pathogens was detected in the microbial community.

A Systematic Review of Denture Stomatitis: Predisposing Factors, Clinical Features, Etiology, and Global Candida spp. Distribution.

Denture stomatitis (DS) is a very common disease in wearers of removable complete and partial dentures with a worldwide prevalence in the range of 20-67%. Both industrially developed and impoverished nations are affected by the illness. DS is often associated with ill-fitting dentures or a fungal infection with Candida spp. Candida is normally found in the oral cavity microbiota, but it can be harmful to the health of elderly people with underlying diseases. Therefore, the purpose of the present study is to offer the most recent information about the epidemiology, etiology, and global distribution of Candida species associated with DS through a systematic review. Several databases, including Medline, Web of Science, and Scopus, were used to conduct an extensive search of the literature published in the previous 20 years. The selection of studies was performed by two authors. The extracted data were as follows: author, year of publication, country, sample, frequency of DS, method of diagnosing stomatitis, species of Candida, risk factors, and etiology of the disease. The JBI Critical appraisal tools were used to assess the quality of the studies. Eventually, twenty-eight studies were included in the systematic review. Twenty-one studies investigated DS, while seven studies examined Candida colonization in patients using removable dentures. The results show that the main causes of DS include the type of dentures, continuous wearing of dentures, and the formation of a Candida biofilm, which is facilitated by poor dental hygiene. Additionally, previous studies have pinpointed the significance of the salivary flow, saliva composition, and salivary pH. The findings of the current review indicate that it is crucial to monitor denture wearers for the appearance of DS, especially the patients whose immunity has been impaired due to a systemic condition. Finally, frequent follow-ups should include a clinical examination and microbial swabs of the palatal mucosa and the mucosal surface of the denture.

Prevalence of denture induced oral mucosal lesions in removable denture wearers

Background: Dentures can cause pathological problems to the oral tissues known as denture-induced mucosal lesions; the most common type is denture stomatitis. Objective: To estimate the frequency of denture-induced mucosal lesions among denture wearer patients attending oral diagnosis clinic /Faculty of Dentistry in Tishk International University. Patients and Methods: A patient who uses either removable partial or complete dentures was included. The patient’s gender and age, denture-related data, and oral lesions induced by dentures were evaluated. The data were statistically analyzed using chi-square and multivariate logistic regression. Results: Oral lesions (23.5%) were more common in males; the lesions found include denture stomatitis, denture hyperplasia, traumatic ulcers, and angular cheilitis. Denture stomatitis was the most common type (7%). The correlation between vertical dimension state and oral lesions was very highly significant. Conclusion: The major cause of denture-induced mucosal lesions was a change in denture vertical dimension and mostly a reduction in vertical dimension. Keywords: Edentulous, dentures-induced mucosal lesions, Denture stomatitis.

Self-perceived oral health

Aim: This study aimed to investigate the relationship between self-perceived oral health and the prosthetic status of individuals who seek care in prosthodontics clinics. Methods: Self-perceived oral health was analyzed through the Geriatric Oral Health Assessment Index (GOHAI). Abutment tooth mobility was assessed, and denture status was determined by clinical assessment of stability, retention, occlusal balance, vertical dimension, and integrity of dentures. The frequency of individuals in each variable was determined for the low and very low GOHAI conditions. Chi-square, Pearson, and stepwise logistic regression tests were used for the statistical analyses (α = 0.05). Results: Ninety wearers of removable dentures with a mean age of 55.1±9.1 years were evaluated. None of the variables was related to GOHAI values (p > 0.05). The regression analysis showed that age predicts (p = 0.006) the variation of GOHAI conditions (OR = 0.924, CI = 0.873- 0.978), showing only 7.6% protective effect against very low GOHAI. Unsatisfactory stability showed the opposite effect (p = 0.034) and the individuals with this characteristic are more likely (OR = 3.055) to have very low GOHAI scores (CI = 1.085- 8.602). Conclusions: The self-perceived oral health of wearers of removable dentures worsens with age and unsatisfactory stability of dentures.

Occurrence of Depression and its Association with Oral Health in Elderly People Living in Old Age Homes of Mathura.

Depression can affect oral health as a result of neglecting oral hygiene procedures which leads to an increased risk of dental caries and periodontal disease. To determine relationship between oral health and depression among elder people residing in old age homes of Mathura city. The study was conducted among 500 subjects aged ≥60 years where dental condition, number of missing teeth, removable denture wearing, teeth mobility, periodontal condition, pocket depth, loss of attachment, and depression according to the Patient Health Questionnaire-9 scale were assessed. Regression analysis showed a positive relationship of the PHQ-9 value with DMFT and MT. Among people aged 60 years and over, severity of depression increased with higher number of MT and DT.

Does occlusal morphology of artificial teeth improve chewing of removable dentures wearers? A systematic review and meta-analysis.

This systematic review aimed to verify whether anatomic, semi-anatomic, or nonanatomic occlusal morphology of artificial teeth improves the masticatory function of complete or removable partial denture wearers. According to the PICO strategy, six databases and the grey literature were searched to identify randomized (RCT) and non-randomized clinical trials (N-RCT) comparing masticatory function, in terms of masticatory performance and efficiency, and muscle activity as primary outcomes; and patient-reported results (O) in individuals using removable dentures (P) with different occlusal morphologies of artificial teeth (I/C). Masticatory ability, satisfaction with the prosthetic treatment, and oral health-related quality of life (OHRQoL) were evaluated as secondary outcomes. Risk of bias was assessed using the Cochrane risk-of-bias tool for randomized trials (RoB 2.0) for RCT and Risk of Bias for non-randomized studies with intervention (ROBINS-I) for N-RCT studies. Meta-analyses were performed to compare primary outcomes and masticatory ability between the occlusal morphologies of artificial teeth of complete or removable partial dentures (α = 0.05). Certainty of the evidence was verified using the GRADE approach. Eleven studies (seven RCTs and four N-RCTs) were included. The risk of bias was considered low for two studies, some concerns for five, and high for the last four studies. Meta-analyses showed that removable partial dentures with anatomic artificial teeth improved masticatory efficiency for carrot chewing (MD 6.31; 95% CI [3.39, 9.22], I2 = 0%). However, masseter and temporal muscle activities increased when removable partial dentures with nonanatomic teeth were used (MD -756.97; 95% CI [-892.25, -621.68], I2 = 100%). Masticatory ability was not influenced by occlusal morphology during chewing of all foods in complete denture users: Carrot (MD -0.88, 95% CI [-8.98, 7.23], I2 = 57%); sausage (MD -8.86, 95% CI [-23.05, 5.33], I2 = 71%); apple (MD -5.78, 95% CI [-28.82, 17.26], I2 = 87%); and cheese (MD -4.16, 95% CI [-15.14, 6.82], I2 = 62%). The certainty of evidence for all evaluated outcomes was very low, mainly due to very serious problems found in the parameters of inconsistency, indirectness, and imprecision. Despite the very low certainty of evidence, the occlusal morphology of artificial teeth influences masticatory function. Anatomic teeth improved the masticatory efficiency and muscle activity of removable partial denture wearers. Nonanatomic teeth increased temporal and masseter muscle activity, which negatively affected chewing in removable partial denture users. However, patients using complete dentures with anatomic and semi-anatomic teeth presented similar masticatory ability.

LEVEL OF PATIENTS’ SATISFACTION WITH THEIR COMPLETE REMOVEBLE PROSTHESES

Taking into consideration the fact that new removable dentures are prepared for edentulous patients of varying ages to improve life-important functions, the dominant criterion for evaluating patient’s satisfaction is the patient's subjective feelings about the dentures. This study is aimed at assessing the level of satisfaction with new removable dentures, manufactures less than a year ago.
 The study included 40 patients with new removable prostheses manufactures within the time period of 3 months to a year before the enrolment. In order to determine patients' satisfaction with their complete dentures, we developed a questionnaire based on a five-level Likert scale, where each respondent could rate their satisfaction with a particular criterion for using complete dentures, from "completely dissatisfied" to "fully satisfied". The statistical analysis of the findings obtained was carried out using the standard IBM SPSS statistics (v.21) software package, employing various methods of descriptive statistics.
 The investigation has demonstrated that among the 40 removable denture wearers, men prevail. 45.0% of patients rated the restoration of the aesthetic configuration of their appearance after the placement of a removable prosthesis as the highest. The profile appearance of the prosthesis and the aesthetics of the false teeth completely satisfied 25.0% (10/40) and 20.0% (8/40) of patients, respectively. The functional effectiveness of removable dentures according to by the Lykert scale was 1.2 times lower for the total assessment of the aesthetic parameters of the constructs (p < 0.05). A quarter of the respondents appreciated the improvement of their chewing function and the quality of fixation of prostheses in the oral cavity.

Usefulness of newly devised food intake score in removable denture wearers.

Although the food intake score (FIS) from conventional food intake questionnaires is widely used, the evaluation method, number of foods and food selection used in the questionnaire can be improved. This study aimed to evaluate the usefulness of a newly devised FIS in removable denture wearers. A total of 219 removable denture wearers were asked about their food intake, and three types of FIS (FIS1, FIS2 and FIS3) were calculated as subjective parameters. FIS1 and FIS2 are conventional FISs, while FIS3 is the FIS devised in this study. The amount of glucose extracted (AGE) when participants chewed gummy jelly was used as an objective parameter. The relationship between the three FISs and that between each FIS and AGE were investigated. Stepwise multiple linear regression analysis was performed with AGE as the dependent variable and age, sex and FIS as independent variables. The three types of FISs were positively correlated. A positive correlation was also found between FIS and AGE. The correlation coefficient was the largest in FIS2 and decreased in the order of FIS3 > FIS1; however, the values of FIS2 > FIS3 were similar. Multiple linear regression analysis revealed that sex and FIS were significantly associated with AGE. For denture wearers, the newly devised FIS3 was useful and evaluated masticatory performance, as well as or better than FIS1 and FIS2.

Influence of Adhesive Use on Swallowing in Removable Complete Denture Wearers

Background: The objective of conventional complete dentures is to reestablish the functions of the stomatognathic system in edentulous individuals. Adhesives are used for denture retention to help the masticatory function. The objective of this investigation was to evaluate the effect of denture adhesive on the swallowing of complete denture wears. Methods: Nine upper and lower complete denture wearers and 14 individuals with teeth were assessed with videofluoroscopy at 30 frames by second and analyzed frame by frame. The denture wears subjects were assessed without dentures, with dentures without adhesive, and with dentures and adhesive. Duplicate assessments were made with swallows of 10-mL thin-liquid bolus, 10-mL extremely-thick bolus, 5-g cookies, and 2-g toasts. Results: Laryngeal vestibule closure, pharyngeal transit, upper esophageal sphincter opening, and oropharyngeal transit took longer in denture wearers than in controls. Laryngeal vestibule closure time and upper esophageal sphincter opening when swallowing thin liquid were shorter with dentures and adhesive than without adhesive. With extremely thick bolus, the pharyngeal transit time and upper esophageal sphincter opening were shorter with adhesive use. Residues in the oral cavity occurred more frequently in the denture wearers than in the controls, for all boluses. Removable complete denture wearers have longer pharyngeal transit of thin liquid and extremely thick boluses, which decreases with adhesive use. Conclusion: Adhesive use cause a favorable effect on pharyngeal swallowing of thin and thick boluses in complete denture wearers.

Masticatory Performance Test Using a Gummy Jelly for Older People with Low Masticatory Ability.

Evaluation of masticatory ability has become more important in an aging society because decreased masticatory ability has the potential to affect the general health of older people. A new masticatory performance test, intended for older people with low masticatory ability, has been developed using gummy jelly half the size of that used in the conventional masticatory performance test. This study aimed to investigate the compatibility between the new and conventional tests and the adaptation of the new test. The new test using the 8-grade visual score with half-size gummy jelly was performed among 137 removable denture wearers (mean age 75.8 ± 9.0 years) with low masticatory performance (a score of ≤4 on a conventional test). The correlation between the scores of half-size gummy jelly (VS-H) in the new test and those of full-size gummy jelly (VS) in the conventional test was evaluated. VS-H among the groups divided by VS were also compared. A strong positive correlation was detected between VS-H and VS (rs = 0.70). In groups with VS of 0 and 1, VS-H values were widely distributed from 0 to 7. There were significant differences in VS-H between the groups with VS of 0-2 but no significant differences in VS-H between the groups with VS of 2-4. Therefore, the masticatory performance test using half-size gummy jelly is suitable for a detailed evaluation of masticatory ability in older people with low masticatory ability when their visual score of full-size gummy jelly in the conventional test is 2 or less.

Evaluation of the hygiene habits and awareness of the removable denture wearer geriatric population: A cross-sectional survey study

Aim: Appropriate denture hygiene promotes the oral health of removable denture wearer elderly patients. This study was conducted to evaluate denture hygiene habits and awareness of the removable denture wearer geriatric population.Methods: A cross-sectional study was carried out by questionnaires which were conducted on 202 volunteered geriatric removable denture wearers at prosthodontics and periodontology clinics. The questionnaires included demographic and denture hygiene habits and awareness information. The collected data were imported to Statistical Package for Social Sciences and the chi-square and Fisher’s exact tests were used to evaluate categorical variables represented as a percentage of study participants.Results: The results of the study reveal that most geriatric patients are aware of effective denture hygiene, but lack correct information. Brushing with soap was the most frequent cleaning method (47.5%). Cleaning only with water and a toothbrush was mostly seen in male participants, while the use of brush and soap, brush and toothpaste and effervescent tablet was mostly seen in female participants (p

Knowledge and Awareness Regarding Denture Staining Amount Complete Denture Wearers: A Descriptive Questionnaire Survey

Introduction: Improper denture hygiene leads to denture staining as well as various lesions of the oral mucosa associated with wearing of removable dentures. The aim of the study is to evaluate the knowledge and awareness regarding denture staining amount complete denture wearers visiting Dental Department, Nobel Medical College and Teaching Hospital. Methods: A descriptive cross‑sectional study was conducted among complete denture wearers visiting Dental Department of Nobel Medical College and Teaching Hospital. A survey was conducted through a printed standard questionnaire with 15 questions delivered to the patients. Data were collected and coded, the statistical analysis was done using SPSS statistical software package. Descriptive statistics were used for data analysis. Results: The study showed that about 38 % of the patients were denture wearers for 6 months to 1 year. About 97% of patients consume coffee or tea regularly. About 65% of the patients consumed aerated beverages. 52% of the patients reported alcohol consumption habits. Tobacco chewing habit was reported by 7% of the patients. 17% of the patients reported cigarette smoking habit. Almost 92.9%% of the patients cleaned their dentures using some or the other method. 64% of the patients claimed to be aware of some or the other denture cleaning techniques. About 20.2% of the patients complained of halitosis, 11% of the patients complained of oral ulcers, and approximately 68.8% of the patients suffered from oral infections. Conclusion: The knowledge and awareness regarding the cleaning and staining of dentures was not adequate among study participants. Patients have habit of consuming tea, coffee, aerated drinks and alcohol which could lead to staining of the acrylic dentures. Therefore, care and hygiene of dental prosthesis including removable dentures is a life-long exercise.

Food Bolus Properties in Relation to Dentate and Prosthetic Status.

The objective of this study is to evaluate food bolus properties (mass, moisture content and food comminution) in patients wearing fixed or removable dental prostheses. Methods: A cross-sectional study was conducted on a convenience sample of patients aged at least 55 years old. Patients chewed a 10 g sample of fresh raw carrot until they felt ready to swallow. The mass of the food bolus was determined as collected and after drying. Food comminution was assessed by the multiple sieve method. Results: Patients with fixed prostheses compared to those with removable prostheses registered a similar mass of food bolus as collected (4.40 g vs. 4.60 g; p = 0.856); a higher mass of dried food bolus (3.46 g vs. 0.86 g; p < 0.001); lower moister of food bolus (24.65% vs. 82.35%; p < 0.001); and better food comminution (mass of smaller particles, of size below 2 mm, represented 65.93% vs. 20% of dried food bolus). In removable denture wearers, food comminution was slightly better in partially than in completely edentulous patients, and rather similar in completely edentulous patients with either implant overdenture or complete denture in the mandible, and complete denture in the maxilla. Conclusions: The current results suggest that food bolus properties are dependent on the dentate and prosthetic status.

The Experiences of Patients Treated with Complete Removable Dentures: A Systematic Literature Review of Qualitative Research

Patient experience has been acknowledged as a critical dimension of healthcare quality alongside patient safety and clinical effectiveness. However, patient experiences in complete removable denture wearing have not been well established qualitatively. The purpose of this review was to synthesize qualitative studies that investigated the experiences of people wearing removable dentures in order to gain a deeper understanding of the issues and their causes. Databases of PubMed, SCOPUS, and CINAHL were searched to assess articles published in English from 2010 to 2021 globally. Qualitative studies that reported on experiences of people wearing removable dentures were included. A total of ten studies were included. People who wear dentures expressed diversified experiences (both negative and positive), including physical, social, psychological processes, and affective responses. Furthermore, experiences were related to emotions, maintenance of dentures, hygiene, access to care, and cost. Those wearing implant retained dentures reported more positive experiences than those who wear conventional complete dentures. Denture wearing experiences is a complex phenomenon involving the patient in wholeness including their environment. Healthcare professionals should be considering a holistic approach when providing denture rehabilitation. There is a need to further explore denture wearing experiences using qualitative approaches, as understanding of patient experiences can inform and provide clear directions on quality improvement initiatives and health-care policy development.

In vitro antimicrobial effects of chitosan on microcosm biofilms of oral candidiasis

ObjectiveThis study assessed the effects of chitosan (CS) on microcosm biofilms derived from saliva of patients with Candida-associated denture stomatitis. MethodsFive removable denture wearers with denture stomatitis were included in the study. The minimum inhibitory concentration (MIC) of CS against clinical isolates of Candida albicans was determined according to the broth microdilution method. Pooled saliva from the donors was used as an inoculum for the formation of biofilms, which were developed during 72 h on acrylic surfaces in the Amsterdam Active Attachment model. The biofilms were then treated with different concentrations of CS, and the antibiofilm effects were evaluated through the quantification of colony-forming units (CFUs), total biomass (TB), metabolic activity (MA), lactic acid production (LAP), and cell viability (by confocal laser scanning microscopy). Chlorhexidine, miconazole, and nystatin were tested as positive controls, while the negative control (NC) was the untreated biofilm. Data were analyzed by 1-way ANOVA and Fischer LSD's post hoc test (α=0.05). ResultsMIC values of CS ranged from 500 to 800 µg/mL. For CFUs, 2500 µg/mL CS was the most effective treatment in reducing total anaerobes, mutans streptococci, and Lactobacillus spp., significantly differing from the controls. For C. albicans CFUs, CS and positive controls did not differ from each other but led to significant reductions compared to NC. Regarding TB, MA, LAP, and cell viability, 2500 µg/mL CS promoted the greatest reductions compared to NC. ConclusionCS has similar or superior effects to conventional active principles on important parameters of oral candidiasis microcosm biofilms. Clinical RelevanceThe antibiofilm effects of CS show that this compound has great potential to improve the clinical condition of denture stomatitis patients, and formulations containing this natural polymer could be useful for controlling oral candidiasis.
