Relation between the risk factors for the severity of denture stomatitis and quality of life of complete edentulous individuals: a cross-sectional study.

To assess the association between risk factors for developing denture stomatitis (DS) and oral health-related quality of life (OHRQoL) in complete denture wearers. Participants of both sexes, wearing complete dentures, were classified using the modified Newton classification for the absence or the severity of DS and allocated to groups Normal or zero, IA, IB, II, and III. Lifestyle, oral and denture history, and medication use were assessed using specific questionnaires; clinical parameters such as anatomical characteristics of support were evaluated with the Kapur classification; salivary flow (SF) was calculated by the volume of unstimulated saliva per minute; and microbial load was determined by counting colony forming units (CFU) of target microorganisms present in the biofilm collected from dentures and palate. OHIP-EDENT assessed the OHRQoL. Kendall's tau_b and Spearman tests were applied with a significance level of 5%. 184 patients (143 female and 41 male) aged 65.5 ± 6.8 years were evaluated. Positive correlations were found for sex (women; p=0.013, r=0.16), individuals who started to consume alcoholic beverages as a young adult (18-27 years) (p=0.008, r=0.22), CFU of Candida spp. (p<0.001, r=0.27 denture; p<0.001, r=0.31 palate); Candida albicans (p=0.004, r=0.22 denture; p=0.003, r=0.25 palate), and Candida glabrata (p=0.004, r=0.22 denture; p=0.001, r=0.27 palate). Moreover, negative correlations with DS were found for CFU of Staphylococcus spp. (p=0.004, r=-0.20 palate) and enterobacteria (p=0.002, r=-0.24 palate), as well as a negative correlation between SF (p=0.009, r=-0.193) and DS. The CFU of Staphylococcus spp. and enterobacteria on the palate significantly correlated with OHRQoL. Being female, consuming alcoholic beverages as a young adult, CFU of Candida spp., Candida albicans, Candida glabrata, and salivary flow may be the most significant risk factors for DS. The microbial load of Staphylococcus spp. and enterobacteria seems to influence the quality of life for complete denture wearers.

Prosthetic Rehabilitation of Parkinson’s Disease Patient with Flabby Ridge Using Modified Window Technique: A Case Report

A flabby alveolar ridge is a mobile soft tissue seen superficially affecting either maxillary or mandibular alveolar ridge. It commonly develops when alveolar bone gets replaced by hyperplastic soft tissue. It is particularly seen in maxillary anterior region of long term denture wearers. Inadequate support stability and retention of complete denture are the problems encountered in these patients. Tremors caused by Parkinsonrsquos disease can make prolonged dental treatment challenging. Various methods are used for managing flabby alveolar ridges which include surgical technique special impression procedures equalized distribution of occlusal forces and implant placement. Special impression technique that involves window technique for flabby ridge has multiple challenges. This case report discusses the use of modified window technique for managing maxillary ridge with flabby area from canine to canine in a Parkinsonrsquos disease patient. This impression technique aids in recording the impressions of the flabby ridges with minimal displacement thus enhancing retention stability and support of the denture.

Rehabilitation of Edentulous Patient with Customized Functional Palatal Contours

Abstract To restore the stomatognathic system of the patient with an edentulous span of 12–13 years who presents flabby tissue in the maxillary tuberosity region, severe resorption in the mandible along with reduced masticatory efficiency, and speech impairments in his old dentures. Complete denture rehabilitation helps patients cope with the significant psychological and social consequences of tooth loss. In today’s image-conscious culture, dentures help sufferers reconnect with the world and re-establishes normal form, function, and esthetics. The most common complaints about prostheses are chewing, as well as poor esthetics and phonetics. Prosthetic rehabilitation for denture wearers should include more than just replacing missing teeth. The ultimate goals should be phonetics, esthetics, and oral function restoration. This article describes a simple, low-cost, practical, and beneficial procedure for the rehabilitation of people with complete dentures who have speech impairment, bone resorption, and flabby tissue. A 71-year-old male patient who is a teacher by profession and has a 30-year habit of chewing kharra paid a visit to the Department of Prosthetic Dentistry at Sharad Pawar Dental College and Hospital in Sawangi, Wardha. He was dissatisfied with his previous dentures because they did not provide adequate chewing quality, pronunciation, or esthetics. After compiling his dental history, it was discovered that he had previously worn dentures for 12 years and had missing teeth due to periodontal disease for 12–13 years. The case report affirms a simple and unique technique for the fabrication of dental prostheses. Palatograms are common, but the technique described in the case report is simple to implement. We achieved both form and function by resolving the issues of residual ridge resorption in the mandibular arch and flabby tissue in the maxillary arch. To summarize, deviations from natural speech immediately following complete denture rehabilitation are completely normal, and a pretreatment speech diagnosis is required for a more accurate comparison. Accustoming the patient to such instantaneous speech deviations must improve his adaptability. Palatograms are useful in identifying these deviations and confirming corrected palatal contours. Simple and low-cost, it is ideal for patients with total dentures and speech disorders.

Exploratory analysis of demographic data, tobacco habits, and oral health-related quality of life among complete denture patients.

The present study assessed the impact of demographics and tobacco habits on oral health related quality of life (OHRQoL) among complete denture patients. Prospective cohort study design. Two hundred and eighty four edentulous patients, aged above 30 years, were chosen as the sample for the study after taking informed consent. Information regarding demographic data and smoking status was obtained from each participant. OHRQoL was evaluated using the Oral Health Impact Profile Edentulousness (OHIP EDENT) quantifying various domains, namely functional limitation, physical pain, psychological discomfort, physical disability, psychological disability, social disability, and handicap. Data were analyzed using the Statistical Package for the Social Sciences version 23.0 (IBM; Chicago, Illinois, USA). Mann-Whitney U test was applied to find significant differences in OHRQoL between gender, age, and smoking status. P < 0.05 was considered to be statistically significant. It was seen that complete denture wearers above 65 years had higher OHIP EDENT scores as compared to younger counterparts suggesting the compromised quality of life in the functional domain which was statistically significant. Psychological discomfort was greater in females while physical disability seemed higher in males. Smoking was found to be a factor associated with decreased OHRQoL. Older age groups, female gender, and smoking were factors associated with decreased OHRQoL among complete denture patients.

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.

РЕЗУЛЬТАТЫ ИССЛЕДОВАНИЙ ДЕНТАЛЬНЫХ ИМПЛАНТАТОВ, УСТАНОВЛЕННЫХ ПАЦИЕНТАМ ПОСЛЕ ПРОВЕДЕНИЯ КОСТНО-ПЛАСТИЧЕСКИХ ОПЕРАЦИЙ ПО УВЕЛИЧЕНИЮ РЕДУЦИРОВАННЫХ АЛЬВЕОЛЯРНЫХ ОТРОСТКОВ ЧЕЛЮСТЕЙ МЕТОДОМ ЧАСТОТНО-РЕЗОНАНСНОГО АНАЛИЗА

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 Health Related Quality of Life in first-time denture wearers Using Balanced, Monoplane and Group function Occlusion

Background: Oral Health Impact profile is one of the most common methods to assess the Oral Health Related Quality of Life (OHRQoL) of the patients. &#x0D; Methods: In this study, a total of 66 edentulous participants were included and divided into 3 groups of 22 each using simple random sampling. OHIP-14 scores were assessed before complete denture treatment and at 6 months follow-up.&#x0D; Results: When comparison of mean OHIP – 14 among the study population across gender before and after denture insertion was done the results were statistically significant. (P-value- 0.001) The difference between the follow-up scores and the scores before a denture when subjected to statistical analysis was significant for all three groups. When one-way ANOVA was done between the groups the data was statistically significant. (P-value

Prospects on Tuning Bioactive and Antimicrobial Denture Base Resin Materials: A Narrative Review.

Denture base resin (DBR) materials are used in dentistry in constructing removable dentures and implant-supported prostheses. A plethora of evidence has demonstrated that DBR materials are associated with a high risk of denture stomatitis, a clinical complication where the soft oral tissues underneath the resin-based material are inflamed. The prevalence of denture stomatitis among denture wearers is high worldwide. Plaque accumulation and the infiltration of oral microbes into DBRs are among the main risk factors for denture stomatitis. The attachment of fungal species, mainly Candida albicans, to DBRs can irritate the underneath soft tissues, leading to the onset of the disease. As a result, several attempts were achieved to functionalize antimicrobial compounds and particles into DBRs to prevent microbial attachment. This review article explored the advanced approaches in designing bioactive and antimicrobial DBR materials. It was reported that using monomer mixtures, quaternary ammonium compounds (QACs), and organic and inorganic particles can suppress the growth of denture stomatitis-related pathogens. This paper also highlighted the importance of characterizing bioactive DBRs to be mechanically and physically sustainable. Future directions may implement a clinical translational model to attempt these materials inside the oral cavity.

Prosthodontic way of overcoming the hurdle of flabby tissues: A case series

Flabby ridges displaceable tissues are a common finding in long term denture wearers. Careful management is mandatory, failing which flabby ridges adversely affect the retention, stability and support of complete dentures. Management of flabby ridges can be driven either surgically or prosthodontically. A list of techniques has been noted in the literature for prosthetically managing flabby tissues such as Zafarullah Khan Technique, modified Zafarullah Khan Technique, Shum &amp; Pow Technique, Hobkirk’s Technique, Palatal splinting using two part tray technique, etc. The decision to consider which material &amp; or technique is appropriate depends on the particular clinical situation. Moreover, the advent of newer dental materials has added to this confusion. The proper diagnosis and planning is required for selecting the material and technique according to the displaceability of the tissues. This article describes a series of clinical scenarios, incorporating these impression techniques and materials for managing the condition.

Decision to use denture adhesive in complete denture wearers after one-month run-in period: A quasi-experimental study.

The aim of this study was to assess two patient-based outcomes of complete denture (CD) wearers who continued or discontinued using denture adhesive (DA) after one-month run-in period of DA use. This quasi-experimental study comprised 76 CD wearers. The two patient-based outcomes were oral health-related quality of life and masticatory performance, determined by the Thai-version of oral impacts on daily performances index and multiple sieve method of 20-stroke peanut mastication. Denture retention and stability were evaluated using the CU-modified Kapur criteria to classify the CD into acceptable or unacceptable quality. The outcomes were collected at 3 time points: 1) at baseline (T0), 2) after a 1-month run-in period of DA use (T1), at which time the participants decided whether to continue using DA, and 3) 1-month after continuing or discontinuing using DA (T2). Changes in the percentages of having an oral impact from T0 to T2 were evaluated using the McNemar's test. The effect of denture quality and the decision to use DA on peanut particle size across time points were assessed using repeated measures ANOVA. The peanut particle size changes in each group between time points were evaluated using the one-way repeated measures ANOVA and Tukey post-hoc comparison test. The participants who continued using DA at T2 had greater oral impact reduction after the 1-month run-in period of DA use, whereas cleaning and emotional impacts emerged in those who discontinued using DA. At T1 and T2, the peanut particle size of the participants who continued and discontinued using DA was not significantly changed from T0, except for the acceptable CD wearers who discontinued using DA at T2, whose peanut particle size decreased from T0 to T2. Baseline oral impacts and their change influenced CD wearers' decision whether to continue using DA. However, masticatory performance did not affect the patients' decision.

In Vitro Antifungal Susceptibility of Candida Albicans Isolated from Yemeni Patients with Denture Stomatitis

Background and aims: Candida-associated denture stomatitis (CADS) is a common fungal infection in people who wear dentures. The main objectives of this study were to identify the causative agents of CADS and in vitro antifungal susceptibility testing (AFST) for Candida albicans in Yemeni patients with denture stomatitis. Methods: A total of 88 Candida spp. obtained from patients with denture stomatitis. Candida spp were identified using standard microbiological methods. The in-vitro antifungal susceptibility of Candida albicans. to fluconazole (FCZ), itraconazole (ICZ), voriconazole (VCZ), and amphotericin B (AMB) was evaluated using the E test strips. Interpretive sensitivity criteria for antifungal breakpoints were adapted from the Clinical and Laboratory Standards Institute (CLSI). Results: Overall, C. albicans was the most commonly isolated species (𝑛 = 60; 68.2%), followed by C. glabrata (𝑛 = 9; 10.2%), C. tropicalis (𝑛 = 7; 8%), and C. parapsilosis (𝑛 = 3; 3.4%). Voriconazole had the lowest geometric mean minimum inhibitory concentration which was 0.0418 𝜇g/ml for MIC50, and 0.957 𝜇g/ml for MIC90; followed by amphotericin B (AMB) in which MIC50 was 0.518 𝜇g/ml and for MIC90 was 1.06 𝜇g/ml. Conclusion: Our study showed that Candida albicans was the most prevalent Candida species in Yemeni patients with CADS and was susceptible to both azoles and amphotericin B. In addition, voriconazole could be a suitable alternative to antifungal agents currently used in the treatment of CADS, as well as in the treatment of recurrent Candidasis.

Knowledge and attitude towards denture adhesives- A survey on complete denture wearers a survey of use of denture adhesives by the denture wearers in Ludhiana city

Denture adhesives have a long been recognized by the denture wearers as a useful adjunct to denture retention and stability. Many practitioners view adhesive usage as a reflection of lack of prosthetic expertise and poor clinical skills. A survey was conducted among complete denture wearers to explore their attitudes towards denture adhesives. The aim of the study was to evaluate the knowledge about denture adhesives among complete denture wearers indicated for use of denture adhesives visiting Dental Colleges in Ludhiana. Patient questionnaire was prepared which consists of 12 questions which were easy for the patients to answer. The survey was conducted on 50 edentulous patients. The patient’s approval was obtained before participation and everything was explained to the patients in their native languages who were not able to understand the questions. It was an observational study in which most of the patients were not using the adhesives for the retention and stability of the denture. About 44% of the patients were using adhesives. Those who were using the adhesives were satisfied with it. Majority of them got adapted to the new denture after the usage of the adhesives. About 56% were not using out of which majority of them were not advised. Those who were using they know the method how to use the adhesives. In conclusion, this study have shown that the majority of the participants that hadn’t tried adhesives because they don’t required them and the participants that used denture adhesives on a regular basis do inform its efficacy.

Influence of Education, Demographic Variables and Duration of Denture Use on Patients’ Satisfaction with Complete Dentures

OBJECTIVE: This study was conducted to determine the influence of education, demographic variables and duration of denture use on satisfaction level among complete denture wearer. METHODOLOGY: A sample of 230 patients, fulfilling the inclusion criteria, were participated in this study. The level of education, demographic details, duration of denture use and patients' satisfaction with complete denture therapy in term of comfort, esthetics, phonetics, chewing, retention and ease of cleaning were recorded by using a questionnaire. Statistical analysis was performed by Statistical Packages for the Social Sciences (SPSS) 20.0. Post-stratification Chi-square test was applied by taking p-value &lt;0.05 as significant. RESULTS: The mean age of the respondents was 60.37±9.055 years, 165(71.74%) were females. Out of 230 respondents, literacy level of 78(33.91%) was matric &amp; above. The average duration of use of denture was 7.09+3.295 months. On the basis of overall satisfaction scores 151(65.5%) patients were satisfied with the denture. There was statistically significant difference in age and patients' satisfaction level with dentures (p&lt; 0.05). CONCLUSION: This study concluded that approximately 65% of the patients are satisfied with complete denture therapy. The demographic variables (except age) and duration of use of denture have no influence on patients' satisfaction level with dentures. KEYWORDS: Edentulism, Complete Denture, Satisfaction

Airway Phenotypes and Nocturnal Wearing of Dentures in Elders with Sleep Apnea

The objective of this study was to examine to what extent the anatomic characteristics of the upper airway can influence the effect of nocturnal wearing of dentures on the sleep of edentulous elders with untreated sleep apnea. This study used the data from a randomized crossover clinical trial and an exploratory approach to address its objectives. Cone beam computed tomography scans of 65 edentulous individuals (female, n = 37; male, n = 28; mean ± SD age, 74.54 ± 6.42 y) with untreated obstructive sleep apnea (OSA) were used to identify anatomic variables. Polysomnography data were collected by means of one portable overnight recording. The respiratory variable values, including apnea–hypopnea index (AHI), with and without denture worn during sleep were used to calculate the change. Statistical analyses included multiple linear regressions, cluster analysis, and binary logistic regressions. A receiver operator characteristic curve was used to illustrate the accuracy of the statistical model. The regression model explained 15.8% (R2) of AHI change. An increase in the lateral dimension of the minimum cross-sectional area was associated with a decrease in AHI, oxygen desaturation index, and respiratory arousal index changes (P ≤ 0.041). Furthermore, an increase in the length of the hypopharynx was associated with an increase in AHI and oxygen desaturation index changes (P ≤ 0.027). An increase in the lateral dimension of the minimum cross-sectional area of the upper airway was associated with a decreased likelihood of being in the group having a worsened AHI (odds ratio = 0.85; 95% CI, 0.76 to 0.95; P = 0.006). An increase in the length of the oropharynx was associated with an increased likelihood of having increased AHI (odds ratio = 1.10; 95% CI, 1.01 to 1.20; P = 0.026). The nocturnal aggravation of respiratory variables in edentulous individuals with OSA who wear dentures at night can be linked to certain anatomic characteristics of the upper airway. Replication of these findings may open novel avenues for personalized advice regarding nocturnal wearing of dentures in edentulous individuals with OSA (ClinicalTrials.gov: NCT01868295).

Expectation of treatment outcomes in complete denture wearers.

Edentulism is a condition associated with age, and the outcome of prosthodontic treatment depends on a number of dental and nondental factors. In complete denture therapy, patient satisfaction is a key objective and various other variables affect this parameter. The ability to foresee its preferences may assist dentists in making informed treatment selections. The study purpose is to assess the expectations of treatment outcomes in complete denture users. For the study, all cases referred for total denture therapy during September 2020 and February 2021 were included. Both new and old denture users completed questionnaires on factors such as retention, mastication, phonetics, esthetics, and comfort. Excel was used to compile the data, which was then imported into SPSS for statistical analysis. The study's statistical significance level was established at P < 0.05. Male patients over the age of 60 years wearing dentures were very common. Denture wearers were highly prevalent in the age group of >60 years among male patients. Retention, esthetics, and phonetics are highly satisfied in existing denture wearers and mastication is highly satisfied in new denture wearers. The comfort factor is commonly satisfied in both the denture wearers. The results were statistically significant with a P = 0.05. Clinician can plan their treatments more effectively if they are aware of the treatment's expectations.

Patient Satisfaction and Oral Health-related Quality of Life (ohrqol) of Edentulous People after Mandibular Denture Relining With a Soft-liner Material: A Pilot Study

Background: Oral health-related quality of life indicators have been effectively used to assess the influence of a range of dental treatments and interventions on patient satisfaction and acceptance. Objectives: The purpose of this study was to evaluate the impact of the relining of mandibular dentures with a soft-liner material, using the Oral Health Assessment Index (OHIP-14). Methods: Forty-two full denture wearers were selected from patients who attended 9 private prosthetic clinics in New South Wales, Australia. All participants had their lower dentures relined with a soft-liner material, according to the manufacturer’s instructions. Oral health-related quality of life was evaluated before and 1 month after relining using the Oral Health Assessment Index questionnaire. A simple descriptive quantitative analysis of the survey results was undertaken, including a comparison of median scores using the Wilcoxon paired test and binomial probability test. Results: In all the outcome variables measured, there was a noticeable positive effect from the denture relining. Specifically, mandibular denture relining with a silicon-based soft-liner material has a positive impact on patient satisfaction and oral health-related quality of life (OHRQoL) of edentulous patients. Conclusion: Patient satisfaction and oral health-related quality of life (OHRQoL) of edentulous patients can be significantly improved by the use of soft-liner materials.

Current Denture Loss in Geriatric Facilities.

Denture loss is still being reported as a problem in geriatric facilities, although losses seem less frequent than in the last decade. However, there have been no reports that have examined recent losses of dentures in detail. The aim of this study was to clarify the actual situation of recent denture loss, together with the denture loss rate in Japan. This retrospective study investigated the number of cases of denture loss, the denture loss rate for denture wearers, and the details of losses in geriatric facilities during the 1-year period from 1 April 2020 to 31 March 2021. Eleven special elderly nursing homes and four group homes participated in this research. The number of residents from each was 315 and 40 and the number of denture wearers was 165 and 33, respectively (p &lt; 0.001). The loss of dentures was found in one case from a special elderly nursing home and in one case from a group home. The loss rate for denture wearers was 1.01% in total, with 0.61% for special elderly nursing homes and 3.03% for group homes, with no significant differences between the two types of facilities. In geriatric facilities in Japan, the current 1-year denture loss rate for denture wearers was 1.01%. This seems to represent a considerable decrease when compared with the previous report. Further, proper denture management and staff efforts appear to have contributed to a reduction in denture loss against a background of promoting oral healthcare.

Association of the number of natural teeth with dietary diversity and nutritional status in older adults: A cross-sectional study in China.

To investigate the association of the number of natural teeth with overall dietary diversity and nutritional status in a nationally representative study among older adults in China. A cross-sectional analysis was conducted among community-dwelling adults aged 65 years or older from the Chinese Longitudinal Healthy Longevity Study. According to the self-reported number of natural teeth, participants were categorized into ≥20, 10-19, 1-9 natural teeth, and edentulous. Dietary diversity score (DDS) was constructed based on intake frequencies of 10 food groups assessed by a simplified food frequency questionnaire. The geriatric nutritional risk index was used to measure the malnutrition status (i.e., normal, mild malnutrition, and moderate-to-severe malnutrition) among a subgroup of participants. Linear and multinomial logistic regression models were used to examine the corresponding associations. Among 54,796 study participants, the mean (SD) age was 87.86 (11.45) years, 82.7% had poor dentition (<20 natural teeth), and 27.3% wore dentures. After multivariable adjustment, participants with poor dentition had lower DDSs (βedentulous =-0.39, 95% confidence interval [CI], -0.48, -0.30; β1-9 teeth =-0.46, 95% CI, -0.55, -0.37; β10-19 teeth =-0.36, 95% CI, -0.46, -0.26) than those with 20 natural teeth or more. For individual food items, edentulous, 1-9 and 10-19 natural teeth were associated with lower odds of regular intake of fresh fruits, fresh vegetables, meat, fish and aquatic products, eggs, legumes, preserved vegetables, tea, and garlic, but higher odds of regular intake of sugar and sweets. Among participants with poor dentition, individuals without dentures had lower intake frequencies of most food groups than those wearing dentures. In addition, poor dentition was related to lower odds of normal nutritional status (odds ratio=0.49, 95% CI, 0.27, 0.89). Older adults with poor dentition had significantly lower dietary diversity and worse nutritional status. Future studies are warranted to identify effective interventions to improve the dietary quality and nutrition status among partially and fully edentulous individuals, including those with Stage IV periodontitis.

Comparative analysis of Candida spp. isolated from complete denture wearers with and without an HIV diagnosis

Statement of problemDenture-related stomatitis (DRS), an inflammation frequently present in human immunodeficiency virus-positive (HIV+) individuals, can be attributable to colonization by Candida spp., which is considered a main factor. The virulence factors of these species are often modulated by the systemic condition of their hosts. PurposeThe purpose of this clinical study was to evaluate the incidence, virulence, and morphology of Candida spp. isolated from biofilms of complete denture wearers with DRS, with and without an HIV diagnosis. In addition, the interaction of the systemic condition with the ability of Candida spp. to colonize was evaluated. Material and methodsFifty-five complete denture wearers diagnosed with DRS were divided into 2 groups: experimental (HIV+) and control (human immunodeficiency virus-noninfected participants [HIV-]). Biofilm was collected by a standardized method of ultrasonification of prostheses. The incidence was evaluated by a chromogenic method and polymerase chain reaction (PCR). The virulence factors were assessed by using the capacity for biofilm formation by counting colony-forming units (CFUs/mL), biofilm metabolism by tetrazolium salt metabolization, and proteinase and phospholipase production by using a fluorimetric kit. Morphology was verified by using the hyphae-inducing test, and participants’ health data were collected with a form. Data were analyzed by using the Student t, Mann-Whitney U, Spearman, and Fisher tests (α=.05). ResultsThe results of incidence were related to 55 participants (22 experimental and 33 control); in total, 63 Candida spp. samples were isolated, showing 28 Candida albicans and 36 nonalbicans strains. No significant difference was found between groups in baseline CFU/mL counts, biofilm formation capacity, cell metabolism, and phospholipase production. Proteinase production was higher for C. albicans in the control (P=.031) and for nonalbicans in the experimental (P=.016) groups. Relative to health data, the experimental group showed a moderate negative correlation between the CFU count/mL at baseline for nonalbicans and DRS classification (P=.020). ConclusionsC. albicans was the most prevalent species. No difference was found in the Candida spp. of complete denture wearers with DRS, with and without an HIV diagnosis, with regard to virulence factors (except for proteinase production) and morphology.
