Oral impact of dental prosthesis use in different patterns of tooth loss.

STATEMENT OF PROBLEM: Tooth loss is a critical indicator of oral health and negatively impacts oral health-related quality of life (OHRQoL) depending on the number and location of the missing teeth. Reports of oral rehabilitation have been conflicting depending on the tooth loss pattern and prostheses provided. PURPOSE: The purpose of this population-based study was to evaluate the association between the use of different dental prostheses according to different tooth loss patterns and OHRQoL. MATERIAL AND METHODS: A representative sample of 22 843 individuals aged between 15 and 75 years was recruited in Brazil. The dependent variable was the OHRQoL as measured by the score on the oral impact on daily performance (OIDP), and the main predictor was the pattern of tooth loss and prosthesis use. Covariates included sex, age, income, education, missing teeth, dental pain, and dental visits. The zero-inflated negative binomial regression was applied with sampling weights. RESULTS: Participants with only anterior missing teeth had an OIDP mean ratio, MR) 1.49 times higher than those without tooth loss and not wearing a prosthesis (95% CI=1.12-1.98); those with a distal extension, with anterior tooth loss MR=1.68 (95%CI=1.17-2.43); and complete edentulism in one or both jaws MR=1.53 (95%CI=1.04-2.25). Participants wearing a removable partial denture (RPD) or a combination of an RPD and fixed prostheses with a few missing teeth reported worse OIDP (MR=3.57, 95% CI=2.11-6.04) than those with fixed prostheses only or without a prosthesis. Individuals with edentulism using complete dentures in both jaws had lower OIDP scores (MR=0.9, 95% CI=0.59-1.37) than those using or those who do not use other categories of prosthetic rehabilitation. CONCLUSIONS: Some types of prosthetic rehabilitation were not associated with better OHRQoL in individuals with tooth loss. The impact of prosthetic rehabilitation was associated with the pattern of tooth loss.

Preventive dental service use and oral health-related quality of life in Brazilian older adults.

BACKGROUND: Information on the use of preventive dental services and associated variables is needed to guide policy for the old adult population and consequently promote better oral health-related quality of life (OHRQoL). OBJECTIVE: To investigate the association between preventive dental service use and OHRQoL by older Brazilians. MATERIALS AND METHODS: This cross-sectional study was carried out using the baseline data of participants of the Brazilian Longitudinal Stud of Aging (ELSEI-Brazil) who were aged 60 years or more. Associations with the use of preventive dental services were carried out using Poisson regression models with robust variance, adjusting for confounders. RESULTS: The final sample consisted of 5432 older adults. Almost all (90.7%) participants reported not having sought preventive dental services in the last year. Individuals who used dental services for prevention had fewer impacts on their OHRQoL (RR: 0.74; [95% CI: 0.57-0.97]). CONCLUSION: Preventive dental service use is associated with a better OHRQoL in older Brazilians. Policies to improve access to preventive dental services may result in improved OHRQoL in this age group.

Predictors of tooth loss in Brazilian older adults: An 8-year follow-up.

OBJECTIVE: To investigate the risk factors for tooth loss after 8 years among community-dwelling older adults in a southern Brazilian city. METHODS: In 2004, 388 dentate community-dwelling older adults from Carlos Barbosa, southern Brazil, were selected using simple random sampling. In 2012, the follow-up consisted of 199 (51.3%) participants. Data collection comprised an interview with data about socio-demographic, behavioural and access to services and an oral examination. The outcome variable of this study is the ratio between the sum of the teeth lost during the 8-year period of follow-up, and the sum of the teeth present in 2004, per person, modelled through binomial regression analysis. RESULTS: Being older (IOR = 1.03, 95% CI: 1.00-1.06), living in a rural area (IOR = 1.56, 95% CI: 1.17-2.07), earning two or more monthly minimum wages (IOR = 1.46, 95% CI: 1.09-1.96), living alone (single, widowed or divorced; IOR = 1.36, 95% CI: 1.00-1.85), having more gingival bleeding sites (IOR = 1.01, 95% CI: 1.00-1.02) and wearing partial removable prosthesis (IOR = 2.82, 95% CI: 2.15-3.71) were risk factors for tooth loss. Approximately 48% of the participants lost one or more teeth over the 8-year follow-up period. CONCLUSION: Socio-demographic, economic and clinical variables were associated with the risk for tooth loss. This might be a result of social determinants of health influencing people's access to oral health care, oral health behaviours and oral health status. Public policy aimed at older adults living in rural areas, living alone and using removable dentures may contribute to reducing the risk of tooth loss.

Residual dentition, prosthesis type and oral health-related quality of life in Uruguayan adults.

OBJECTIVES: To investigate the association between different types of dental prostheses (and residual dentition) and oral health-related quality of life (OHRQoL). METHODS: A population-based study with a representative sample of adults and older adults in Uruguay (2010-2011). The dependent variable was the score on the oral impact on daily performance (OIDP), and the main predictor was the pattern of tooth loss and prosthesis use. Covariates included sex, age, socioeconomic status, education, missing teeth, pain and decayed teeth. Negative binomial regression was used. RESULTS: The sample comprised 762 participants. Those participants not wearing a prosthesis and with extensive tooth loss had a mean OIDP of 3.1 (95% CI = 1.6-6.2), while those wearing removable partial dentures (RPD) and having <12 missing teeth had a mean OIDP of 3.6 (95% CI = 1.3-10.0). Participants with a free-end saddle had the highest mean OIDP, at 4.9 (95% CI = 2.0-12.1). For participants with ≤12 missing teeth, any additional missing tooth was associated with an 11% higher OIDP score. Participants who wore RDPs reported fewer impacts on OHRQoL if they had extensive tooth loss or anterior tooth loss than those with a free-end saddle, or who had lost fewer teeth. CONCLUSIONS: The use of RPDs is associated with better OHRQoL. These findings may be valuable in clinical practice and prosthetic planning.

Current status of geriatric dentistry education in selected dental schools in Latin America and the Caribbean.

OBJECTIVE: Latin American and Carribean (LAC) are currently experiencing a rapid aging of their population, coupled with a significant burden of oral diseases. Despites this, there is a scarcity of evidence regarding the manner in wich geriatric dentistry is being taught in dental schools across LAC. So, the objective of this study is to investigate the current status of geriatric dentistry education at undergraduate and postgraduate levels in selected LAC dental schools. METHODS: An electronic questionnaire was developed and emailed to all 539 dental schools in 19 LAC countries. The questionnaire recorded activity levels, contents and methodology of geriatric dentistry education as part of dental degree programmes. Reminders by email and telephone calls were used to encourage non-responders to complete the questionnaire. RESULTS: In total, 317 schools from 17 countries responded to the questionnaire (response rate: 58.8%). Geriatric dentistry was taught in 54.6% of the schools at the undergraduate level and in 6.9% at the postgraduate level. Thirty two percent of the schools had a programme director trained in geriatric dentistry. Geriatric dentistry was taught as an independent course in 14.5% of the schools. Dry mouth, periodontal disease, denture-related conditions and prosthodontic management, oral mucosal disease and age-related changes of the orofacial complex were the most frequently covered topics. Clinical teaching of geriatric dentistry was reported by 26.5% of the schools, with 38.0% providing clinical training in outreach facilities. CONCLUSIONS: Geriatric dentistry education remains incipient in LAC, with only one in every four dental school offering it as a standalone course. There is an urgent need to further develop geriatric dentistry education in the continent, including further research to develop a minimum geriatric dentistry curriculum.

Using Voice Change as an Indicator of Dysphagia: A Systematic Review.

Voice change post-swallow, observed during a clinical swallow examination, is often used as a clinical indicator of dysphagia risk. However, there has been limited research that evaluated the level of agreement between voice change and swallow dysfunction reported to date. This systematic review aims to investigate existing evidence relating to the relationship between vocal change post-swallow and swallow deficits identified on a Videofluoroscopic Swallow Study (VFSS). The studies were selected by two independent evaluators for inclusion, without restriction on language or date of publication and the methodological quality and the risk of bias were assessed using QUADAS-2. Following the PRISMA recommendation, 271 articles were analyzed, of which 17 were included in the study. Of these, the methodology described in five studies employed voice analyses using only acoustic methods, seven others conducted only auditory-perceptual analyses, and five other studies used both. Across the studies there was no homogeneity in the voice quality parameters assessed, analytic methods used, and results obtained. Forty seven per cent of the studies presented a high risk of bias in the analysis of vocal quality due to lack of clarity and blinding of VFSS. There was no homogeneity in the choice of consistencies evaluated during swallowing, as well as standardization of the outcome investigated in VFSS without a vocal parameter attributable to accurate detection in each outcome. It is not possible to obtain a consensus regarding the recommendation of the use of vocal evaluation as an accurate method for identifying swallowing alterations due to heterogeneity of the vocal evaluation methods, the outcomes evaluated in the VFSS examination, heterogeneity in food and liquid consistencies, and the methodological quality of the studies.

Effect of oral exercises and photobiomodulation therapy in the rehabilitation of patients with mandible fractures: randomized double-blind clinical trial.

Mandible fractures compromise stomatognathic functions, requiring rehabilitation. Evaluate the effectiveness of photobiomodulation (PBM) associated with oral exercises for rehabilitation of patients with mandible fractures. In this randomized clinical trial, we compared PBM with PBM sham in 14 adults with mandibular fractures who underwent surgical intervention. The sessions were performed 24 h and 48 h after surgical procedure, and weekly for 4 weeks after hospital discharge. Both groups performed oral exercises after each PBM session. Restriction of food consistencies, mandibular mobility, pain, and facial sensitivity measured before and after the surgical procedure were the outcomes evaluated, one and 3 months after surgery. Maximum interincisal distances (MID), exercise pain, and restriction of food consistencies were also evaluated during each week of intervention. Both groups showed normal MID (> 35 mm) and food consistencies consumed 1 month after the surgical procedure, with no significant differences between them. Individuals in the PBM group had less pain response to exercise during all the weeks of intervention than the sham group (p < 0.05). The patients presented a reduction in the painful response in MID and mandibular laterality movements 1 month after surgery compared to the preoperative period. In contrast, there was an improvement in laterality in the sham group only 3 months postoperatively and persistent pain in MID. There was no significant difference in facial sensitivity within and between groups during follow-up. The performance of oral exercises associated with PBM effectively facilitated the early rehabilitation of oral functions, with significant gains in pain management.

Virtual learning object for developing knowledge about the diagnosis and management of molar incisor hypomineralization.

AIM: To develop, apply, and evaluate a virtual learning object (VLO) for teaching undergraduate dental students and paediatric dentists to diagnose and manage molar incisor hypomineralization (MIH). DESIGN: This controlled educational intervention included 170 undergraduate dental students and 50 paediatric dentists. The student intervention group (VLOG) was trained by the VLO, the control group of students (CG) received a synchronous virtual class, and the group of paediatric dentists (PDG) was trained by the VLO. Pre-test and post-test data were analyzed with a mixed one-way and Tukey's post hoc ANOVA test (α = 0.05). The answers to the questionnaire were analyzed with the one-way ANOVA test and Tukey's post hoc test (α = 0.05). RESULTS: The values obtained in the pre-test were significantly lower than those obtained in the post-test for all groups. The specialists showed a higher level of knowledge before and after the MIH training compared with the students (p < .001). Similarly, statistical differences were found in the level of knowledge, which increased after MIH training (p < .001). There were no differences between the CG and VLOG. CONCLUSIONS: The level of knowledge increased in all groups after training regardless of the method used. VLOG works similar to traditional teaching approaches.

Swallowing impairment in older adults: association with sensorimotor peripheral nerve function from the Health, Aging and Body Composition study.

BACKGROUND: The purpose of this study was to examine whether impairments in sensorimotor peripheral nerve function are associated with a higher likelihood of swallowing impairment in older adults. METHODS: Health, Aging and Body Composition participants (n = 607, age = 75.8 ± 2.7 years, 55.8% women, 32.3% black) underwent peripheral nerve testing at Year 4 and 11 with swallowing difficulty assessed at Year 4 and 15. Nerve conduction amplitude and velocity were measured at the peroneal motor nerve. Sensory nerve function was assessed with the vibration detection threshold and monofilament (1.4-g/10-g) testing at the big toe. Symptoms of lower extremity peripheral neuropathy and difficulty swallowing were collected by self-report. Data analysis was performed using a hierarchical approach. Odds ratios (ORs) were estimated using non-conditional logistic regression. RESULTS: At Year 15 108 (17.8%) participants had swallowing impairments. In fully adjusted models, the peripheral nerve impairments associated with swallowing impairment were numbness (OR 4.67; 95%CI 2.24-9.75) and poor motor nerve conduction velocity (OR 2.26; 95%CI 1.08-4.70). Other peripheral nerve impairments were not related to swallowing. CONCLUSIONS: The association between slow motor nerve conduction velocity and numbness and a higher likelihood of swallowing difficulties a decade later in our prospective study identifies an important area for further investigation in older adults.

Is dietary pattern a mediator of the relationship between socioeconomic status and dental caries?

OBJECTIVE: To investigate whether a healthy diet and added sugar mediate the relationship between socioeconomic status and oral health status in adults. METHODS: This is a secondary cross-sectional analysis of adult participants from the 2015-2016 National Health and Nutrition Examination Survey from the United States (n=3367). Structural equation modeling tested direct and indirect pathways from a latent variable for socioeconomic status to oral health via healthy eating (Health Eating Index) and added sugar in a multiple-mediator multiple-outcome model. RESULTS: Added sugar was directly associated with untreated dental caries [Standardized coefficient (SC)=0.10], and healthy eating was directly associated with both untreated dental caries (SC=-0.11) and tooth loss (SC=-0.05). Higher socioeconomic status was associated with lower untreated dental caries through direct (SC =-0.246) and small indirect paths via healthy diet (SC= -0.026), lower consumption of added sugar (SC=-0.007), and dental visits (SC=-0.162). Higher socioeconomic status was associated with fewer teeth lost through direct (SC =-0.306) and very small indirect paths via healthy diet (SC=-0.016), added sugar consumption (SC=-0.001), and untreated dental caries (SC=-0.094). CONCLUSIONS: Both socioeconomic status and dietary pattern independently contributed to tooth loss and dental caries. The contribution of dietary factors as a mediator to socioeconomic inequities in oral health was small, and statistically significant. CLINICAL RELEVANCE: A systems approach to socioeconomic inequities in oral health takes into account the complex relationships between socioeconomics, dietary patterns, oral health and health. Socioeconomic conditions and nutrition, as common risk factors to noncommunicable disorders, should be tackled in programs to improve oral health.

Sexual behavior and its association with persistent oral lesions: analysis of the POP-Brazil study.

OBJECTIVES: To investigate whether the presence of persistent self-reported oral lesions (PSOLs) is associated with sexual behaviors and with the presence of sexually transmitted infections (STIs) in individuals aged 16-25 years in the state capitals of Brazil. MATERIALS AND METHODS: Data from the POP-Brazil study were analyzed. An association analysis was performed by Poisson regression with the presence of PSOLs as the outcome. The exposure variables were the age at first sexual intercourse, the number of partners, oral sex practice, and aspects of condom use for model 1, and the presence of a self-reported STI or a positive rapid test for HIV/syphilis and the presence of genital human papillomavirus (HPV) for model 2. The results were adjusted for socioeconomic variables. RESULTS: The prevalence of PSOLs was 76% higher among individuals who had two or more sexual partners in the past year (p = 0.046) and 68% higher in those who reported not using condoms for contraception (p = 0.032). The group with HIV/syphilis or self-reported STI had a 140% higher PSOL prevalence (p = 0.003). CONCLUSIONS: The self-report of oral lesions in adolescents and young adults may suggest risky sexual behavior and the presence of STI. CLINICAL RELEVANCE: It is necessary to contextualize the reality of the young person to optimize oral health care.

External control of fluoridation in the public water supplies of Brazilian cities as a strategy against caries: a systematic review and meta-analysis.

BACKGROUND: Among the methods currently available to provide fluoride in population levels, fluoridated water is the most successful for presenting high efficacy, safety and good cost-benefit. However, recent studies on external control have shown great variability of fluoride concentrations in the water from treatment stations in Brazilian cities, which must present concentration between 0.6 and 0.8 mg/L to be considered acceptable in most cities. Thus, this study aimed to perform a systematic review of the literature to assess the adequacy of fluoride concentration in the water in Brazilian cities using external control. METHODS: The protocol was registered in PROSPERO. Six databases were used as primary search sources and three databases were used to partially capture the "gray literature". Only observational studies that assessed the fluoride concentration of artificially fluoridated water from the public supply network were included. The JBI Critical Appraisal Tools for Systematic Reviews was used to assess the risk of bias of the studies. A proportion meta-analyses using random-effect models were performed. The heterogeneity between studies was determined by I2 statistic. Meta-regressions were conducted to identify relevant moderators to be used in stratified meta-analyses. Publication bias was investigated by Egger's tests. RESULTS: The search provided 2038 results, from which 14 met the eligibility criteria and were included in the data extraction of the review. Overall, the water samples were collected from 449 different sources in three Brazilian regions. Thirteen studies presented a low risk of bias. The mean concentration of fluoride ranged from 0.17 to 0.89 ppmF. The meta-analyis demonstrated that more than half of the water samples analyzed had fluoride concentration levels outside the acceptable range (56.6%; 95% CI 45.5; 67.3), with high heterogeneity. CONCLUSION: More than half of the public water supply analyzed in the studies selected had fluoride concentration levels outside the acceptable range, which may affect the risk of developing oral diseases in the Brazilian population, having an important impact on public health.

Maternal characteristics, home environment, and other factors associated with traumatic dental injuries in preschool children.

BACKGROUND/AIMS: The importance of external factors such as maternal and home characteristics on traumatic dental injuries needs to be investigated. The aim of this study was to evaluate the association between maternal and home characteristics and dental trauma in preschool children. MATERIAL AND METHODS: This cross-sectional study using a cluster random sample evaluated children between 3 and 4 years of age from Porto Alegre, Brazil. Mothers completed the Brazilian version of the Beck Depression and Anxiety Inventories (BDI and BAI). They answered questions about sociodemographics, maternal behaviors, and home characteristics. Dental trauma was assessed by the Children's Dental Health Survey criteria. Malocclusion and deleterious habits were also assessed. The multinomial logistic regression model was used to investigate the association of exploratory variables with different categories of dental trauma. Odds ratios (OR) and 95% confidence intervals were calculated. RESULTS: A total of 163 pairs of children and mothers agreed to participate (78.4% response rate). The prevalence of dental trauma was 49.8%. Mother's work outside the home, overjet, and anterior crossbite were associated with the occurrence of enamel trauma, while having a younger mother, families having more siblings, and having a mother with university education were associated with increased odds of dentin/pulp trauma. CONCLUSION: Depression and anxiety in the mothers were not associated with dental trauma, while malocclusion characteristics were more relevant for less severe, enamel trauma. Socioeconomic and home environment characteristics played a role in more severe, dentin/pulp trauma.

Factors associated with hyposalivation and xerostomia in older persons in South Brazil.

OBJECTIVE: This study aimed to investigate characteristics associated with xerostomia and hyposalivation in older persons. BACKGROUND: Saliva is one of the most important body fluids and plays an important role in food bolus formation, lubricating the oral mucosa and protecting teeth against demineralisation. MATERIALS AND METHODS: This is a cross-sectional study nested within a cohort and includes a sample of 872 older persons living independently in the community, both in rural and urban areas in Carlos Barbosa, Brazil. Data collection included standardised interviews to identify sociodemographic, behavioural and health-related variables, as well as oral clinical examination performed by two trained/calibrated dentists. Poisson regressions with robust variance were used to calculate the crude and adjusted prevalence ratios (PR) and their respective 95% confidence intervals. RESULTS: The mean age was 68.5 ± 6.7 years, and the majority of the sample consisted of women (65.3%). The prevalence of xerostomia, of low stimulated salivary flow rate and low at rest salivary flow rate were 338 (38.8%), 494 (56.6%), 320 (36.7%), respectively. In the final adjusted model, women had a significantly increased prevalence of xerostomia (PR = 1.34; 95% CI: 1.12-1.61), as well as participants taking medication continuously (PR = 1.45; 95% CI: 1.16-1.82) and those with depressive symptoms (PR = 1.49; 95% CI: 1.27-1.76). Lower at rest (PR = 1.45, 95% CI: 1.22-1.72) and lower stimulated salivary flow were more prevalent in women (PR = 1.27, 95% CI: 1.11-1.44), while lower stimulated salivary flow was more prevalent in older persons taking medication continuously (PR = 1.24, 95% CI: 1.07-1.43). CONCLUSION: Salivary hypofunction and xerostomia were more prevalent in women and in those with continuous medication use; however, depressive symptoms were associated only with xerostomia. Measures are required to promote oral comfort in cases of xerostomia, thereby reducing the unpleasant sensation of dry mouth and hyposalivation consequences in clinical practice.

Motivational Interviewing in Preventing Early Childhood Caries in Primary Healthcare: A Community-based Randomized Cluster Trial.

OBJECTIVE: To assess the effectiveness of motivational interviewing in preventing early childhood caries compared with conventional oral health education. STUDY DESIGN: Twelve health care units in southern Brazil were randomly allocated in 2 groups of 6 and professionals in 1 group were trained in motivational interviewing. The mothers/children and external examiners were blinded to the intervention. The data were collected by calibrated examiners using questionnaires and a clinical examination based on modified International Caries Detection and Assessment System criteria. Of the 674 children born in the catchment area in the year 2013, 469 received the intervention (224 in the conventional oral health education group, 245 in the motivational interviewing group), and 320 were examined by the end of the study (145 in the conventional oral health education group, 175 in the motivational interviewing group), with mean age of 30 months. The final follow-up was 68%, after 3 years. RESULTS: Mean of decayed, missing, and filled surfaces at the end of the study period for the whole sample was 1.34 (95% CI 0.97-1.71). The caries rate per 100 surface-year in the conventional oral health education group was 1.74 (95% CI 1.14-2.34) and in the motivational interviewing group, it was 0.92 (95% CI 0.63-1.20). To correct for clustering effect and unbalanced factors, multilevel Poisson regression was fitted and the effect of motivational interviewing on the incidence rate ratio was 0.40 (95% CI 0.21-0.79). CONCLUSIONS: An intervention based on the principles of motivational interviewing style was more effective in reducing the number of surfaces affected by early childhood caries compared with conventional oral health education intervention.

Caries progression as a risk factor for increase in the negative impact on OHRQOL-a longitudinal study.

OBJECTIVES: The aim of this study is to evaluate the association between caries lesions progression and oral health-related quality of life (OHRQoL) among Brazilian preschools, after 2 years. MATERIALS AND METHODS: At baseline, 163 children (3-4 years old) enrolled in 12 public primary care services in Porto Alegre/RS-Brazil were evaluated. After 2 years, 119 children were re-evaluated. Calibrated examiners employing the ICDAS criteria conducted clinical examinations. A socio-demographic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale were applied to the parents of the children at baseline and 2-year follow-up. Data analysis was performed using a hierarchical approach based in a conceptual framework testing by Poisson regression. RESULTS: The number of surfaces that progressed from baseline to 2-year follow-up was associated with an increased negative impact on OHRQoL. CONCLUSIONS: Caries progression increased the negative impact on OHRQoL. CLINICAL RELEVANCE: The progression of caries lesions could negative impact on OHRQoL in Brazilian preschoolers.

Influence of dental factors on oropharyngeal dysphagia among recipients of long-term care.

OBJECTIVE: The study evaluated the association of the sociodemographic, behavioural variables and the oral conditions with the presence of oropharyngeal dysphagia in long-term care older persons. BACKGROUND: Due to the influence of ageing, swallowing may be altered both in people with natural teeth and in those who have dentures or tooth loss. MATERIALS AND METHODS: This cross-sectional study evaluated 115 individuals older than 60 years, living in long-term care institutions of the State of Rio Grande do Sul in 2016. The diagnosis of dysphagia happen using a clinical speech evaluation, based on the research of signals and symptoms of alterations during deglutition, and on an oral sensory-motor evaluation. The dental clinical evaluation examined the oral cavity, teeth and dental prostheses, including a Xerostomia assessment. Poisson Regressions with robust variance was calculated were used to estimate crude and adjusted Prevalence Ratios(PR) and their IC95%. RESULTS: The sample was mostly comprised of older women (67.0%), with more than 81 years of age (44.3%) and edentulous (54.3%). Diagnosis of oropharyngeal dysphagia was verified in 60.9% of the participants. In the final model, older persons who presented no pair (PR=1.52(CI95%=1.02-2.40)) had a highest prevalence of oropharyngeal dysphagia, when compared to older persons who presented 8 to 14 mixed pairs, as well as those older persons who had more complaints related to symptoms of Xerostomia (PR=2.86(CI95% 1.58-5.18)). CONCLUSION: Institutionalised older persons with a poor oral health condition are associated with a higher prevalence of oropharyngeal dysphagia, as well as with the presence of Xerostomia.

Predictors of Satisfaction with Dentures in a Cohort of Individuals Wearing Old Dentures: Functional Quality or Patient-Reported Measures?

PURPOSE: To examine the extent to which denture satisfaction can be determined by a measure of the denture's functional quality and by patient-reported measures. MATERIALS AND METHODS: This study used data obtained from 117 edentulous individuals with a mean age of 73.7 (SD = 5.6) years in southern Brazil. The edentulous individuals rated their levels of general satisfaction with their actual dentures, using a visual analog scale. Explanatory variables included the individual's information about ability to chew, ability to speak, esthetics, and sociodemographic factors. The dentures were evaluated using the validated 9-item Functional Assessment of Dentures instrument. Bivariate statistical analyses and Poisson regression models (prevalence ratio [PR]; 95% CI; p < 0.05) were used to test the association of explanatory variables with patients' general satisfaction with their complete dentures. RESULTS: There was a statistically significant association between patients' general satisfaction and stability of maxillary (rocking movement) (adjusted PR = 1.28; 95% CI: 1.07-1.52) and mandibular dentures (occlusal displacement) (adjusted PR = 1.68; 95% CI: 1.16-2.43), masticatory ability (adjusted PR = 1.54; 95% CI: 1.08-2.19), and the age of the mandibular denture (adjusted PR = 1.47; 95% CI: 1.10-1.97). CONCLUSIONS: The results of this study indicated that measures of denture stability, masticatory ability, and age of dentures appeared to be determinants of patients' satisfaction with dentures.
