Effect of denture cushion adhesives and a liner on retention and masticatory efficiency in complete denture wearers

РОЛЬ ЧАСТОТНО- РЕЗОНАНСНОГО АНАЛИЗА В ИССЛЕДОВАНИИ ДЕНТАЛЬНЫХ ИМПЛАНТАТОВ, УСТАНОВЛЕННЫХ В РЕКОНСТРУИРОВАННЫЕ АЛЬВЕОЛЯРНЫЕ ОТРОСТКИ С НЕБОЛЬШИМ ОБЪЕМОМ КОСТИ ЧЕЛЮСТЕЙ

The use of dental implants being the intraosseous artificial fixtures is often required for orthopedic rehabilitation of completely edentulous patients; for their placement, adequate amount of bone tissue is needed, which in many cases is insufficient due to physiological bone loss, long-term wearing of full dentures, the duration of edentulism and complex clinical situations caused by maxillofacial injuries or general somatic diseases. Implant placement in the above situations requires timely preparation of deficient alveolar ridge by means of osteoplastic surgery. In its turn, the newly formed regenerated bone by its histological, physicomechanical and structural-functional properties can only approach the recipient bone tissue; therefore, the issue of implant osseointegration and its functional loading in regenerated bone remains debatable. This research uses the method of frequency-resonance analysis showing implant stability coefficient numerically equal to the ISQ (Implant stability Quotient) values and reflecting the percentage of the osseointegration area of the intraosseous part of the implant. The results of research obtained by means of frequency-resonance analysis have proved that with the timely start of implant usage and adequate functional loading, ISQ values increase, that is, increases the osseointegration area along the interface of the intraosseous part of the implant placed in regenerated bone. Comparative results of research reflecting ISQ values in 12 months after implant placement in bone augmented using various forms of autogenous bonegrafts, have been presented; therefore, a conclusion can be made that there is a direct relationship between osseointegration under conditions of functional chewing load and the shape and size of autogenous bonegrafts.

Oral Hygiene Status among Denture and Non-denture Wearers in a Tertiary Health Care Centre: An Analytical Cross-Sectional Study

Oral Hygiene Status among Denture and Non-denture Wearers in a Tertiary Health Care Centre: An Analytical Cross-Sectional Study

PHYSIOLOGICAL AND SOCIO-ECONOMIC SATISFACTIONLEVEL OF PATIENTS FOR ACRYLIC AND CAST ALLOY DENTURES

Background: The ultimate loss of dentition creates lot of oral problems for edentulous patients which can be prevented with the provision of acrylic or cast alloy denture but patient satisfaction level attributed to these dentures is still unknown. We evaluated patient satisfaction level regarding aesthetics, pain, cost, retention, comfort and speech between acrylic and cast alloy denture wearers. Methods: Freshly edentulous patients wearing complete dentures with acrylic resin denture (AD) (n=65) and Co-Cr cast alloy denture (CD) (n=65) took part in study. Smart Patient Satisfaction Questionnaire was used to investigate satisfaction of these patients after one month (AD-1 and CD-1) and then after 3 months (AD-3 and CD-3). Scoring system 0=Not-Satisfied, 1=Satisfied and 2=Well Satisfied was used to evaluate general satisfaction of patients in both groups regarding speech, taste, pain, aesthetics, comfort, cost, and retention. Results: Patient satisfaction level between AD and CD wearers displayed insignificant differences with respect to aesthetics (p=0.614), pain (p=0.842), retention (p=0.852), comfort (p=0.842), speech (p=0.943), and taste (p=0.753). Patient satisfaction level between AD and CD users related to cost was significant (p=0.001) depicting that AD group was more satisfied with cost as compared to CD users. Conclusions: Both groups were satisfied with their aesthetics, pain control, retention, comfort, speech, and taste but patients using AD were found to be more satisfied with cost as compared to CD users who found these dentures quite expensive.

Denture-induced fibromatous hyperplasia - case report

<p><strong>Introduction.</strong> Denture-induced fibrous hyperplasia (DFH) is a reactive lesion that occurs as a result of chronic trauma caused by the denture on the oral mucosa.</p> <p><strong>Case report.</strong> A female patient, 56 years old, reported to the Specialist Center for Dentistry at the Faculty of Medicine in Foča for the fabrication of complete dentures. She wore previous complete dentures for about 25 years and complained about their age and discoloration. Clinically, both dentures were poorly retained and stabilized by short wings, with pronounced signs of wear. Denture hygiene was poor. Multiple folds of hyperplasic connective tissue were observed in oral cavity upper vestibule mucosa. The lesion folds were pink and firm, corresponding to denture edges. Based on the anamnesis and clinical examination, a temporary diagnosis of denture-induced hyperplasia was made. The patient was informed about clinical condition assessment as well as possible therapeutic procedures and gave written consent to accept the offered therapeutic procedures. She was advised not to wear dentures for four weeks and to maintain proper oral hygiene. After that, the hyperplasia was surgically removed under local anesthesia. A tissue sample was sent for pathohistological analysis. A new pair of total dentures was made. Removed tissue pathohistological examination confirmed the diagnosis: “Epulis fissuratum”.</p> <p><strong>Conclusion.</strong> Education and regular check-ups are essential for the prevention of DFH. Patients should be given detailed oral and written instructions on oral and denture hygiene maintenance, with special reference to possible changes in oral tissues and the importance of regular follow-ups.</p>

Different Polymers for the Base of Removable Dentures? Part II: A Narrative Review of the Dynamics of Microbial Plaque Formation on Dentures.

This review focuses on the current disparities and gaps in research on the characteristics of the oral ecosystem of denture wearers, making a unique contribution to the literature on this topic. We aimed to synthesize the literature on the state of current knowledge concerning the biological behavior of the different polymers used in prosthetics. Whichever polymer is used in the composition of the prosthetic base (poly methyl methacrylate acrylic (PMMA), polyamide (PA), or polyether ether ketone (PEEK)), the simple presence of a removable prosthesis in the oral cavity can disturb the balance of the oral microbiota. This phenomenon is aggravated by poor oral hygiene, resulting in an increased microbial load coupled with the reduced salivation that is associated with older patients. In 15-70% of patients, this imbalance leads to the appearance of inflammation under the prosthesis (denture stomatitis, DS). DS is dependent on the equilibrium-as well as on the reciprocal, fragile, and constantly dynamic conditions-between the host and the microbiome in the oral cavity. Several local and general parameters contribute to this balance. Locally, the formation of microbial plaque on dentures (DMP) depends on the phenomena of adhesion, aggregation, and accumulation of microorganisms. To limit DMP, apart from oral and lifestyle hygiene, the prosthesis must be polished and regularly immersed in a disinfectant bath. It can also be covered with an insulating coating. In the long term, relining and maintenance of the prosthesis must also be established to control microbial proliferation. On the other hand, several general conditions specific to the host (aging; heredity; allergies; diseases such as diabetes mellitus or cardiovascular, respiratory, or digestive diseases; and immunodeficiencies) can make the management of DS difficult. Thus, the second part of this review addresses the complexity of the management of DMP depending on the polymer used. The methodology followed in this review comprised the formulation of a search strategy, definition of the inclusion and exclusion criteria, and selection of studies for analysis. The PubMed database was searched independently for pertinent studies. A total of 213 titles were retrieved from the electronic databases, and after applying the exclusion criteria, we selected 84 articles on the possible microbial interactions between the prosthesis and the oral environment, with a particular emphasis on Candida albicans.

Binary Logistic Regression Analysis on the Association of Occlusion with the Temporomandibular Joint Arthralgia in the Partial Denture Wearers-A Retrospective Study.

To analyze the potential association between the occlusion features and the incidence of temporomandibular joint (TMJ) arthralgia in patients with partial dentures. A total of 101 partial denture wearers were collected, 45 with unilateral TMJ arthralgia diagnosed according to the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Binary logistic regression analysis was adopted. The TMJ asymptomatic group (n = 45) was quantified as 0, while the TMJ arthralgia group (n = 56) was quantified as 1. In total, 13 occlusion variables were analyzed: gender, age, number of prosthetic teeth, number of dentition quadrants with a prosthetic tooth, anterior or posterior prosthesis location in maxillary or mandibular dentition, occluded prosthesis pair, anterior overjet, and overbite relation. Simple and multiple binary logistic models were adopted, accordingly, for the risk impact of them on TMJ arthralgia. Overbite (OR = 2.238) and maxillary anterior prosthesis (OR = 0.305) were entered into the simple binary logistic model; while overbite (OR = 2.774) plus maxillary anterior prosthesis (OR = 0.347), overbite (OR = 3.425) plus unilateral maxillary posterior prosthesis (OR = 4.672), and overbite (OR = 3.476) plus overjet (OR = 0.436) and mandibular anterior prosthesis (OR = 0.177) were entered into the multivariate logistic regression model (all, P < .05). Partial denture wearers with a deep overbite, especially those with a unilateral maxillary posterior prosthesis, had a higher prevalence of unilateral TMJ arthralgia.

The Effect of Ciplukan Leaves Extract (Physalis minima) Effervescent Tablets as an Denture Cleanser to the Growth Candida albicans

Denture stomatitis is one of the problems that often occurs in denture wearers. Prevention of denture stomatitis can be done by immersing the denture in a cleaning solution. Ciplukan leaves (Physalis minima) are natural ingredients that can be used for denture cleaning because they contain antimicrobials. This study aims to determine the effect of effervescent tablets of ciplukan leaf extract (Physalis minima) as a denture cleanser in inhibiting the growth of C. albicans. Methods: This type of research is a laboratory experiment with the post-test-only control group design. The sample used is acrylic resin plate made of heat curing acrylic material The samples used were 24 pieces with a size of 10x10x1 mm which were divided into 4 treatment groups. Samples were immersed in alkaline peroxide effervescent tablets and ciplukan leaf extract effervescent tablets with concentrations of 25%, 50%, and 75% for 20 minutes. The number of C. albicans colonies was counted using a spectrophotometer and converted into the formula. The results of the One-Way ANOVA statistical test showed that the number of C. albicans in each treatment group was significantly different with a significance value of 0,00. Ciplukan leaf extract effervescent tablets were able to inhibit the growth of C. albicans on heat cured acrylic resin plates with the most effective concentration of 75%.

Comparative Evaluation of Antifungal Property of Acrylic Resin Reinforced with Magnesium Oxide and Silver Nanoparticles and their Effect on Cytotoxic Levels: An In vitro Study

Abstract Background: About 65% of people who wear dentures suffer from denture stomatitis, a prevalent pathologic illness that is commonly linked to Candida albicans. The necessity for the creation of polymethyl methacrylate (PMMA) materials with intrinsic activity is brought on by increasing resistance of microbes. The study’s objectives were to examine and compare the antifungal properties of acrylic resin by adding silver nanoparticles (AgNPs) and magnesium oxide nanoparticles (MgONPs), as well as to determine its cellular toxicity at various nanoparticle concentrations on mouse fibroblasts. Materials and Methods: A total of 84 samples were created, including 12 control samples, 36 samples of PMMA resin reinforced with AgNPs, and 36 samples of PMMA resin reinforced with MgONPs. Disk diffusion technique was used to assess the antifungal effectiveness of the samples. By using the MTT test, the cytotoxicity of various nanoparticle concentrations was evaluated. Analysis of variance test and unpaired t-test were used to analyze the data, and then Tukey’s post hoc test was performed. Results: The mean values for AgNPs and MgONPs at 2%, 4%, and 6% after 24 h were 13.71 ± 2.07, 18.58 ± 1.62, and 27.96 ± 1.76 and 11.63 ± 1.35, 14.38 ± 1.63, and 18.25 ± 1.39, respectively. In contrast to the MgONPs group, samples with AgNPs showed greater antifungal efficacy against C. albicans. On mouse fibroblasts, MgONP concentrations showed more cytotoxicity, but AgNP concentrations showed less cytotoxicity. Conclusion: By adding AgNPs and MgONPs to acrylic resins, which are highly efficient against C. albicans, denture stomatitis can be treated.

Paraqitja e stomatitit dhe të gjeturat citologjike te bartësit e protezave totale

The aim of this research was to determine cytologi- cal changes in wearers of acrylic-based complete den- tures. The study was conducted at the Prosthodontics Clinic in the Clinical Dental Center of the University Clinical Center of Kosovo (UCCK). The study included an experi- mental group (EG) and a control group (CG). Samples for cytological analysis were taken from oral mucosa areas in close contact with the denture base from both groups. The samples were analyzed in the pathology laboratory. Statistical data were analyzed using descriptive statistics and values expressed in percentages. A high keratinization index was recorded in the EG, while no keratinization was found in the CG. The picnotic and eosinophilic indexes were either not found at all or were low. Granular debris in 58.0% of the EG had low presence, moderate in 30.0%, and considerable in 8.0%. A low number of granulocytes were found in 68% of the EG, and a moderate presence in 34.0%. In 88% of the CG and 86% of the EG, erythrocytes were not found to be present. A weak presence of bacterial flora was recorded in 64.0% of the CG and 82% of the EG. Epithelial cells were recorded in both CG and EG at 60.0%. Parabasal cells were not found to be present in 96.0% of the CG and 100.0% of the EG. The presence of interstitial cells was significantly present in 100.0% of the CG and 94% of the EG. The wearing of complete dentures manifests with keratinous changes in oral mucosa. To control these changes, it is necessary to alter patients’ oral hygiene practices, focusing on cleaning and disinfecting the dentures, removing them for 24 hours during the night or even during the day for intervals of 6 to 8 hours within a day.

Evaluation of photodynamic therapy efficacy vs. conventional antifungal therapy in patients with poor-fitting dentures suffering from denture stomatitis. A prospective clinical study

BackgroundThe long-term use of antifungal therapy in denture stomatitis (DS) treatment could be accompanied by antifungal-resistant strain onset, leading to compromised therapeutic procedure and disease reappearance. Photodynamic therapy (PDT) has shown the ability to eradicate oral infections and resistance strains. This prospective clinical study aimed to assess the PDT's effectiveness compared to the conventional treatment on clinical and microbiological parameters in patients with DS without denture wear during the treatment and follow-ups. MethodsForty-two patients diagnosed with DS were randomly assigned to one-session single PDT application (test group) or conventional antifungal therapy (control group). Clinical and microbiological parameters were assessed and analyzed before and at 3rd, 15th, and 30th day following the treatments. Microbiological samples were analyzed by a Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry. The data was statistically analyzed. ResultsPrior to the treatment, Candida species, including C. albicans (100%), C. glabrata (33%), C. tropicalis (31%), C. krusei (31%) were isolated in all patients. Both treatment procedures demonstrated a statistically significant reduction in C. albicans at all follow-up time intervals (p < 0.05). However, PDT displayed a statistically significant reduction in C. krusei compared to the conventional treatment at all follow-up periods (p < 0.05). Clinical parameters improved considerably in the test group compared to the control group at the 3rd and 15th day of follow-up. ConclusionOne-session single PDT application demonstrated significant improvement in both clinical and microbiological outcomes in a short-term period, resulting in complete Candida spp. eradication compared to conventional antifungal therapy.

Risk factors for oral frailty among community-dwelling pre-frail older adults in Japan: A cross-sectional analysis.

Oral frailty is a well-established risk factor for frailty and plays a significant role in progression to frailty. However, the association between oral frailty and pre-frailty in elderly individuals remains unclear. This cross-sectional study aimed to clarify the characteristics and risk factors of pre-frailty in elderly individuals with oral frailty. A total of 377 elderly individuals participated. Oral examinations comprised simple and non-invasive measures of chewing function, self-reported swallowing function, and oral moisture. The frailty screening index was used to assess frailty phenotypes. The overall prevalence of pre-frailty was 63.1%, after excluding 40 frail and 99 robust individuals. The mean age of the pre-frail participants was 76.6 ± 5.8 years; 70.6% were women. 10.5% of the pre-frail elderly participants had oral frailty. In multivariate analysis diabetes mellitus, history of cancer, denture wearing, and malnutrition were independently associated with oral frailty among pre-frail elderly individuals (adjusted odds ratio (OR) 3.8, 95% confidence interval (CI) 1.06-13.54; OR 4.5, CI 1.32-15.36; OR 8.8, CI 1.76-43.78; and OR 3.6, CI 1.30-9.67; respectively). The prevalence of oral frailty was low among community-dwelling pre-frail elderly individuals. Early interventions involving oral, nutritional, and disease management may prevent or improve oral frailty in pre-frail elderly individuals and may prevent progression to frailty. Further studies are required to elucidate the underlying mechanisms.

Evaluation of Clinical Periodontal Parameters of Abutment Teeth Supporting Distal-Extension Base Removable Partial Dentures: A Cross-sectional Study.

To assess the clinical periodontal status of abutment teeth in regards of different design components of distal-extension removable partial dentures. Subjects (N=100) with acrylic or cobalt-chromium distal-extension removable partial dentures were enrolled and their periodontal parameters plaque and gingival indices [PI, GI], probing depths [PD], clinical attachment loss [CAL] and a mobility index [MI] evaluated. Denture base type, major connector, occlusal rests position, design of direct retainers, retention, stability and denture wearing habits were further evaluated. Acrylic RPDs were associated with higher mean±SE PI [1.70±0.74], GI [1.76±0.55], PD scores [2.47±1.02 mm] and CAL values [4.46±2.11 mm] compared to CO-CR RPDs [p⟨0.05]. For abutments, the PI [1.6±0.83], GI [1.72±0.57], PD [2.32±1.03] and CAL [4.26±2.08] were higher than their non-abutments counterparts [p⟨0.05]. CAL scores were found to be significantly higher for mandibular abutments compared to maxillary ones [P=0.002]. The highest PI [1.83±1.10] and GI [2.00±0.00] scores were associated with lingual bars and horse-shoe connectors, respectively. Full palatal coverage and lingual plates were associated with the highest PD [2.80±0.48] and CAL [4.70±0.37] scores. Acrylic RPDs, type of major connector, wrought wire clasps and distal occlusal rests may be considered as risk factors for periodontal disease progression in distal-extension removable partial denture wearers.

Effect of Propolis on Fungal Infection for Denture Wearers and Dry Socket

Propolis is consist of various amounts of resins and beeswaxes that produced by the honeybees from different natural plants, as leaf buds and flowers. It is a sticky and dark-brown color material that produced by honey bees from natural plants that the bees mixed it with wax and applied it in building, construction and adaptation of the nests specially in repair cracks and defects in the bees hive. They have been used in medical folk or medical traditional since times of ancient. It is now known to be natural medical treatment with, antifungal, antibacterial, antioxiditive, antitumor and mmunomodulatory properties. These medical properties of propolis are motivating isolation researches, identification of the possible relationship of these with its biological activity, and chemical compounds. It was used in dentistry for healing of surgical wound (or post-surgical mouth pain), tooth hypersensitivity, pulp capping and root canal treatment. Propolis has a promising goal in future medically. This research shows the application of propolis, clinically, as a natural dental medicine. Furthermore; systemic and clinical applications of these drugs may have some adverse effects like liver toxicity, drug interactions etc. Using propolis as antifungal by local application shown that it reduces the incidence of dry socket and denture stomatitis that associated with the Candida. In present study, the propolis has been used in the following manner. It is applied to the tissue surfaces of dentures, two times daily for two weeks. Propolis putty can also applied to dry socket cases after complete debridement and irrigation of it. The results showed after use propolis that the signs and symptoms including pain, redness and inflammation areas related stomatitis were gradually disappear, after 2 to 14 days the denture stomatitis is healing by using a propolis paste. Propolis putty has an effect on the fungal infection of dry socket that gradually reduced pain and inflammation until complete healing. Aim of the study, after the treatment of patients with denture stomatitis, they were subjected to examination and evaluation of the mucosa and socket, Candidal quantitative cultures and confirmation the diagnosis by three methods: Germ tube, Gram Stain, and ChromAgar media.

Identification of Candida Albicans Infection on Denture Wearing According to the Sex and Type of Denture Base Materials

Background: Oral Candidiasis is a wide opportunistic infection of the mouth due to an overgrowth of Candida species, the most being Candida albicans. Its harmless commensally organism inhabiting the mouth, but it will change into a pathogen, invade tissue, and cause acute and chronic diseases. The predisposing factor for infection with Candida was dentures in about sixty-five percentages of older peoples who are wearing full upper dentures. Objective: This research aims to determine the sex distribution of fungal infection in corresponding with fungal infection among groups (acrylic and metal denture base). Patients &amp;Methods: Sixty-eight patients attend the private dental clinic were subjected to usual dental treatment. They were divided into two groups: group 1: included 43 (24 females and 19 males) with acrylic denture base wearers. As well as, group 2: metal denture base wearers in 25 (10 females and 15 males). Questionnaire Paper to determine demographic data include, if patient take any fungal or antibiotic or not (treated and non-treated) and would obtain from the patients by including sex, age, and nocturnal wear. Result: The results in this study found that the prime etiology of Candida growth was the prosthesis materials itself. Sixty-five percent of the wearers of dentures showed Candida growth, while thirty-five percent of patients who had their dentitions showed Candida growth that the appliances are the dominant etiological factors in the growth of Candida other local factors should be considered.

Effect of Denture Wearing on Occurrence of Fungal Isolates: An Original Study.

The present study aimed to evaluate the effect of denture wearing on the occurrence of fungal isolates in the oral cavity before and after complete denture insertion. Fifty completely edentulous patients were selected. Swab samples were collected intraorally before the fabrication of complete dentures from the palatal mucosal surface and after complete denture fabrication (1 and 7 days after denture insertion). Further, these samples were inoculated and incubated. Results showed that in 48 patients, no isolate of fungus before denture insertion was found. In two subjects, results were false positive (contamination from the environment), and in six patients, there was an increase in growth, but not much significant increase of growth was seen (mild growth of fungus only after denture insertion). One of the major findings of this study was that the overall occurrence of fungal isolates (before and after denture insertion) in the oral cavity was not significant.

Evaluation of Physical Properties of Denture Base Resins Containing Silver Nanoparticles of Aloe barbadensis Miller, Morinda citrifolia, and Boesenbergia rotunda and Its Anti-microbial Effect: An In Vitro Study.

Introduction The denture bases fabricated from polymethylmethacrylate (PMMA) have some disadvantages, such as surface prone to microbial growth and biofilm accumulation, which contributes to the onset and dissemination of infections among denture wearers. Therefore, the purpose of this in vitro study was to evaluate the flexural strength, hardness, and antimicrobial effect of denture base resin incorporated with 0.05% and 0.1% silver nanoparticles (AgNPs) of Aloe barbadensis miller (aloe vera), Morinda citrifolia (noni), and Boesenbergia rotunda (finger root). Materials and methods A total of 84 PMMAsamples were used and were divided into three groups. Flexural strength tests were performed on Group 1 PMMAblocks. Group 2 involved hardness testing of PMMAblocks, whereas Group 3 involved antimicrobial activity. Each group was subsequently split into seven subgroups with differing concentrations of AgNPs: Sub Group 1: control (no AgNPs),Sub Group 2: 0.05% aloe vera AgNPs, Sub Group 3: 0.1% aloe vera AgNPs, Sub Group 4: 0.05% noni AgNPs, Sub Group 5: 0.1% of noni AgNPs,Sub Group 6: 0.05%finger root AgNPs, and Sub Group 7: 0.1% finger root AgNPs.The flexural strength was evaluated usinga universal testing machine (Instron 8801). Surface hardness was measured using a Vickers tester (Tukon 1102). For the antimicrobial activity analysis, the samples were incubated in a suitable culture broth containing Candida albicans for 24 hours. Microbial colony count (colony-forming unit (CFU)/mL) was estimated to evaluate the microbial adhesion to the surface of the denture base materials. Statistical analysis The flexural strength, hardness, and CFU between the groups were analyzed using one-way analysis of variance (ANOVA) followed by multiple comparisons with Tukey's honest significant difference (HSD) test (α=0.05). The level of statistical significance was determined at p<0.05. Results It was observed that the mean flexural strength was maximum in PMMA incorporated with 0.05% of aloe vera AgNPs and least in PMMA incorporated with 0.1% noni AgNPs. It was seen that a steady loss in flexural strength is observed from 0.05% to 0.1%. The mean hardness was maximum in PMMA incorporated with 0.1% of noni AgNPs and least in PMMA incorporated with 0.05% aloe vera AgNPs. It was also found that the hardness was directly proportional to the number of nanoparticles. With an increase in the weight percentage of nanoparticles, a steady increase in hardness was seen in all the test groups. In our study, the results showed that finger root 0.1% showed the least CFU with a significant reduction of C. albicans adherence; therefore, it indicates higher anti-fungal activity. Aloe vera 0.05% showed the lowest inhibition of C. albicans,suggesting the least anti-fungal activity. Conclusion Within the limitations of this study, It can thus be concluded that the addition of AgNPs incorporated with plant extracts of Aloe barbadensis miller (aloe vera), Morinda citrifolia (noni), and Boesenbergia rotunda (finger root) can alter the flexural strength, hardness, and microbial adhesion of PMMA. In our study, it can be concluded that flexural strength increases with the addition of AgNPs of 0.5% concentration after which a steady loss is seen. However, the hardness and antimicrobial activity increased with an increase in the concentration of AgNPs in all three plant extracts.

Association Between Candida albicans and COVID-19 in Complete Denture Wearers: An Observational Study.

Introduction The phenomenon of coronavirus disease 2019 (COVID-19)-related candidiasis is gaining increased attention and acknowledgment as an integral component of the severe consequences of COVID-19. The aim of the present study was to assess the association between Candida albicans and COVID-19 in complete denture wearers. Materials and methods An observational study was conducted on 45 complete denture wearers, who were divided into three groups as follows: Group 1, 15 subjects with mild to moderate COVID-19 infection; Group 2, 15 subjects with severe COVID-19 infection; and Group 3, 15 subjects without COVID-19 infection. Mean colony forming units (CFU) were observed on agar plates containing Sabouraud dextrose in the salivary samples of the participants. Analysis of variance, followed by post-hoc analysis by Tukey's test, was used to compare CFU between the groups. Pearson's correlation coefficient was used to study the correlation between variables. Results The highest average colony-forming units of Candida albicans were observed in Group 2, followed by Group 1, compared to the control group, and a significant (p<0.001) difference was found. A weak positive correlation was found between the age of the patients and the duration of denture usage, as well as between age and the counts of Candida albicans in Groups 1 and 3. This correlation was more pronounced in Group 3. A strong positive correlation was observed in all groups between the Candida albicans count and the duration of denture usage by the patients. Conclusion The association between Candida albicans and denture wear was compounded by the presence of COVID-19. Consequently, the timely identification of Candida albicans infection in patients with COVID-19 is important to establish more efficacious approaches for antifungal treatment and prophylactic interventions.

Evaluation of the Empower model of care for partial denture clients in a public oral health care setting.

To evaluate the effectiveness of the Empower model of care (EMC) on reducing the addition of teeth to removable partial dentures (RPD). Data reports were generated through the Titanium electronic database to retrieve all clients at Monash Dental Services (MHDS) who participated in the EMC or received an RPD prior to the implementation of EMC was assessed over a two-year period to determine if they had additional teeth added to their partial dentures (PD). A logistic regression was performed testing whether a combination of socio-demographic and clinical variables, provided a multivariate explanation of the EMC outcome. Prior to EMC, 2034 patients attended MHDS requiring RPDs with 363 returning to have teeth added. From 2018 to 2020, 38 of 584 participants in EMC returned to have teeth added to their PDs. Those in the 'High' risk group were two times more likely to return requiring additional teeth (OR = 1.99; 95%CI:1.31-3.02); each additional year of age increased the odds of requiring additional teeth (OR = 1.03; 95%CI:1.02-1.04). Participants of the EMC were more than two times less likely to require additional teeth (OR = 0.42; 95%CI:0.29-0.59). The variance in requiring additional teeth accounted for using the full model was 9.1% (η2 = 0.091). This analysis confirms the effectiveness of the EMC. This approach assists denture wearers to maintain good oral health and provides an effective way of managing public health funds by reducing denture repairs and additions. © 2023 Australian Dental Association.
