Denture Wearers (denture + wearer)
Kinds of Denture Wearers Selected AbstractsImpaired mastication modifies the dynamics of bolus formationEUROPEAN JOURNAL OF ORAL SCIENCES, Issue 3 2006Claude Yven Mastication is a complex sensory-motor activity whereby a food product is transformed into a bolus. Consumers mainly perceive the sensory properties of the food during the intra-oral manipulation of the product. Consequently, the quality of the chewing process could have consequences on the perception of sensory properties and food choice. By focusing on meat products, this study aimed to analyze the influence of dental status on (i) dynamic adaptation of the chewing behavior (evaluated by electromyography) to the changes in texture during bolus formation and (ii) bolus properties (mechanical resistance and saliva incorporation) obtained from meat of different initial textures. Two groups of subjects (dentate subjects and denture wearers), known to present highly different chewing efficiency, were compared. For both groups, salivary flow rates were evaluated at rest and after stimulation by chewing (paraffin and meat). The salivary flow rates, assessed during chewing of a nonedible matrix (paraffin), were a good predictor of salivary flow rates induced by meat chewing for both groups of subjects. Salivary flow rates were not affected by the dental status. In contrast, the chewing behavior varied between groups. For denture wearers, the chewing pattern was strongly impaired and not adapted to the changes in meat structure during bolus formation. Denture wearers swallowed less fragmented boli than dentate subjects, but boli had a similar level of moisture for both groups of subjects. [source] The relationships between oral status, physical and mental health, nutritional status and diet type in elderly Japanese women with dementiaGERODONTOLOGY, Issue 4 2008Shinsuke Sadamori Objectives:, To suggest methods for maintaining an adequate nutritional status for elderly patients with dementia by evaluating the relationships between oral status, physical and mental health, and feeding conditions. Background:, Feeding difficulties in dementia patients are related to food intake, and failure to eat may be associated with weight loss in long-term care facilities. The relationship between compromised oral function and diet is still unclear. Materials and methods:, A cross-sectional study of 94 elderly women with dementia (mean age 89.6 ± 5.6 years) from a nursing home was undertaken to investigate their oral, physical and mental and nutritional status. Results:, There were significant differences in serum albumin (p = 0.0284), N-ADL (p = 0.0005), NM scale (p = 0.0004) and HDS-R (p = 0.0004) between denture wearers and non-denture wearers. However, there were no significant differences in body mass index between denture wearers and non-denture wearers. Conclusion:, A suitable type of diet and assistance with feeding could maintain the nutritional status of elderly patients with dementia if they are still feeding themselves. The nutritional support team will benefit from the participation of a dentist. [source] Patients' experiences with partial dentures: a qualitative studyGERODONTOLOGY, Issue 4 2005Patricia A. Smith Objective:, The aim of the study was to gain insight into people's experiences of being given and using partial dentures. Methods:, In-depth semi-structured interviews were carried out with 23 people of varied age, social background and denture wearing experience in Tayside, Scotland. Participants were encouraged to discuss how they came to have partial dentures, their day-to-day denture use and their interactions with dentists. The interview data were systematically coded using key theme headings, and summary charts were constructed to facilitate analysis. Results:, The initial decision that a partial denture was needed was generally difficult to accept. People perceived the main benefits of partial dentures to be improved appearance and confidence, but experienced a variety of difficulties with their dentures and often coped with these by only wearing them on social occasions. Participants had not always told their dentists about the difficulties they experienced. Barriers to seeking help with denture problems included financial constraints, previous experience of rushed appointments or poor communication from dentists and a perceived lack of entitlement to help when partial dentures were issued free. Conclusions:, Partial dentures can be difficult to cope with. People experience a range of difficulties in wearing them, not all of which have been discussed with dentists. Informative and supportive communication when partial dentures are first needed, and subsequently, can improve the quality of patients' experiences and may help promote effective use and appropriate help-seeking by partial denture wearers. [source] Impact of Human Genome Project on treatment of frail and edentulous patients,GERODONTOLOGY, Issue 1 2004Ichiro Nishimura Objective:, Because of ongoing increases in life expectancy and deferment of edentulousness to older age, dentists are facing a different challenge to satisfy elderly denture wearers with a higher prevalence of chronic diseases. This discussion introduces the Human Genome databases as novel and powerful resources to re-examine the core problems experienced by frail and edentulous patients. Background:, Recent studies demonstrated that mandibular implant overdentures do not necessarily increase masticatory function, perception and satisfaction in denture wearers with adequate edentulous residual ridges. It has been demonstrated that the rate of edentulous residual ridge resorption significantly varies among individuals. The prognosis and cost-effectiveness of denture treatment, with or without implants, may largely depend on how the edentulous ridge is maintained. However, reliable clinical methods permitting dentists to predict the long-term health of the edentulous residual ridge are lacking. Materials and methods:, With the completion of the Human Genome Project, the genomic sequence database from this multinational consortium will provide a unique resource to determine the genetic basis of similarity and diversity of humans. Results:, One base pair in every 100 to 300 base pairs of the genome sequence varies among humans, suggesting that genetic diagnosis using the single nucleotide polymorphisms (SNPs) may provide a novel opportunity to differentiate our edentulous patients. Conclusions:, Future dental service for the elderly will require a personalized care paradigm, using highly sensitive diagnostic technology such as SNP genomic analysis, for recommending the treatment with greatest potential benefit. [source] Oral microbial flora and oral malodour of the institutionalised elderly in JapanGERODONTOLOGY, Issue 2 2001Eiki Honda Abstract Objectives: To determine the oral health status, especially the level of oral microbial flora and oral malodour, of institutionalised elderly people compared with non-institutionalised elderly people. Setting: Three institutions and numerous private homes. Subjects: 56 institutionalised and 56 non-institutionalised elderly people. Main Outcome Measures: Institutionalised elderly people had higher levels of Candida, staphylococci, and oral malodour. Results: Institutionalised elderly people had a higher level of Candida in denture wearers, and a higher level of staphylococci and oral malodour compared with the non-institutionalised elderly. Conclusion: The institutionalised elderly have a higher risk of opportunistic infections and oral health care should be improved to protect them from these infections and to reduce oral malodour. [source] Comparisons between a mixing ability test and masticatory performance tests using a brittle or an elastic test foodJOURNAL OF ORAL REHABILITATION, Issue 3 2009T. SUGIURA Summary, A variety of chewing tests and test items have been utilized to evaluate masticatory function. The purpose of this study was to compare a mixing ability test with masticatory performance tests using peanuts or gummy jelly as test foods. Thirty-two completely dentate subjects (Dentate group, mean age: 25·1 years) and 40 removable partial denture wearers (RPD group, mean age: 65·5 years) participated in this study. The subjects were asked to chew a two-coloured paraffin wax cube as a test item for 10 strokes. Mixing Ability Index (MAI) was determined from the colour mixture and shape of the chewed cube. Subjects were asked to chew 3 g portions of peanuts and a piece of gummy jelly for 20 strokes, respectively. Median particle size of chewed peanuts was determined using a multiple-sieving method. Concentration of dissolved glucose from the surface of the chewed gummy jelly was measured using a blood glucose meter. Pearson's correlation coefficient was used to test the relationships between the MAI, median particle size and the concentration of dissolved glucose. Mixing Ability Index was significantly related to median particle size (Dentate group: r = ,0·56, P < 0·001, RPD group: r = ,0·70, P < 0·001), but not significantly related to glucose concentration (Dentate group: r = 0·12, RPD group: r = 0·21, P > 0·05). It seems that ability of mixing the bolus is more strongly related to the ability of comminuting brittle food than elastic food. [source] Validation of video versus electromyography for chewing evaluation of the elderly wearing a complete dentureJOURNAL OF ORAL REHABILITATION, Issue 8 2007E. NICOLAS summary, Chewing efficiency may affect nutritional status in the elderly. Many elderly patients are complete denture wearers, and often present cognitive problems. Those two factors make evaluation of mastication difficult with experimental methods. Analysis of video recording may be a simple way to routinely assess chewing parameters. This study aimed at validating several parameters of video evaluation versus electromyography (EMG), which is considered the ,gold standard'. The design was a prospective randomized study, carried out at the Faculty of Dentistry, University of Auvergne, Clermont-Ferrand, France. Twelve complete denture wearers chewed four model foods differing in hardness. Sessions were videotaped and EMG recordings were registered. Mastication time, number of masticatory cycles and cleaning time were recorded simultaneously by video and EMG. Two investigators independently analyzed the videos twice, in random order. Evaluation of criterion validity: a positive video/EMG correlation was found for the parameters ,chewing time' (0·89, Pearson) and ,number of masticatory cycles' (0·94, Spearman), whereas no statistical difference was found between these two EMG and video variables (t -test). Inter and intra-rater reliability gave a positive intraclass coefficient (ICC) for duration of mastication (0·86,0·98), number of masticatory cycles (0·90,0·97) and cleaning time (0·90,0·98). Discriminatory ability was studied using anova (P = 0·01): variation was significant in masticatory duration (F = 10), number of masticatory cycles (F = 10) and cleaning time (F = 4). Video may be a useful assessment tool in prosthetic rehabilitation and can be applied to help choose the type of food (solid, semi-liquid or liquid) to administer to dependent persons, particularly those suffering from dementia. [source] Quality of life and masticatory function in denture wearersJOURNAL OF ORAL REHABILITATION, Issue 5 2006H. KOSHINO summary, Successful prosthodontic treatments for a patient with removable partial dentures including maxillofacial prostheses hopefully brings about psychological wellbeing as well as improved health. The purpose of this study was to investigate the relationship between quality of life (QOL) and the various aspects of denture function. At first, a questionnaire with a visual analog scale with 16 question items concerning denture and/or eating problems, the present state of health, psychological and physical wellbeing, life satisfaction, and QOL was developed. To discuss the validity and reliability of the questionnaire, 48 outpatients who wore a denture were asked to fill it out. Next, to discuss the difference in QOL of the patient with various kinds of dentures and conditions, 103 outpatients were asked to complete the newly developed questionnaire. The questionnaire which contained four factor areas with eight questions for denture patients was developed by factor analysis with Varimax rotation. The reliability of the QOL scale was confirmed by reliability analysis (Cronbach's ,=0·784). The QOL score of edentulous patients with a complete denture having some trouble chewing was significantly lower than that of other denture patients. It was suggested that the wearing of a denture significantly affected the QOL of elderly persons. [source] Surface EMG of jaw-elevator muscles and chewing pattern in complete denture wearersJOURNAL OF ORAL REHABILITATION, Issue 12 2005M. G. PIANCINO summary, The aim of this study was to investigate the adaptation process of masticatory patterns to a new complete denture in edentulous subjects. For this purpose, muscle activity and kinematic parameters of the chewing pattern were simultaneously assessed in seven patients with complete maxillary and mandibular denture. The patients were analysed (i) with the old denture, (ii) with the new denture at the delivery, (iii) after 1 month and (iv) after 3 months from the delivery of the new denture. Surface electromyographic (EMG) signals were recorded from the masseter and temporalis anterior muscles of both sides and jaw movements were tracked measuring the motion of a tiny magnet attached at the lower inter-incisor point. The subjects were asked to chew a bolus on the right and left side. At the delivery of the new denture, peak EMG amplitude of the masseter of the side of the bolus was lower than with the old denture and the masseters of the two sides showed the same intensity of EMG activity, contrary to the case with the old denture. EMG amplitude and asymmetry of the two masseter activities returned as with the old denture in 3 months. The EMG activity in the temporalis anterior was larger with the old denture than in the other conditions. The chewing cycle width and lateral excursion decreased at the delivery of the new denture and recovered after 3 months. [source] Oral health in relation to wearing removable dentures provided by dentists, denturists and laboratory techniciansJOURNAL OF ORAL REHABILITATION, Issue 7 2003R. TuominenArticle first published online: 5 JUN 200 summary, The aim of this study was to evaluate the oral health of elderly Finnish men wearing removable dentures supplied either by dentists, denturists or laboratory technicians. From a sample of 550 men, 362 subjects were both interviewed and clinically examined. The subjects were asked a range of questions related to their oral health and dentures. Clinical examinations were carried out by one dentist using well-defined criteria and without knowing the information the respective subjects had given in the interview. The 242 denture wearers had a higher frequency (P < 0·001) of mucous membrane lesions (78·7%) than the 120 non-wearers (27·5%). Differences between the denture providers were small, although subjects with dentures provided by dentists had less often most of the recorded mucous membrane lesions than other denture wearers. Coating of tongue and cheilitis angularis were the most commonly encountered lesions. High levels of yeast growth were observed more frequently (P < 0·02) among subjects who had obtained their dentures from dentists (41·3%) than from either denturists (17·1%) or laboratory technicians (18·2%). Among dentate subjects, the average number of remaining teeth was higher (P < 0·05) among those who had obtained their dentures from dentists (8·7) than among subjects wearing dentures from denturists (5·9) or laboratory technicians (6·2). Subjects wearing dentures supplied by dentists had slightly better oral health than other denture wearers. The observed differences can be at least partly explained by dentists' patients having higher number of remaining teeth and also more frequent check-up visits. [source] Oral hygiene habits, denture cleanliness, presence of yeasts and stomatitis in elderly peopleJOURNAL OF ORAL REHABILITATION, Issue 3 2002Y. Kulak-Ozkan The purpose of this study was to determine oral hygiene habits, denture cleanliness, presence of yeasts and denture stomatitis in elderly people. Seventy complete denture wearers were investigated clinically and mycologically. Subjects were evaluated according to, presence of denture stomatitis, presence of yeasts, denture cleanliness, frequency of denture brushing and denture cleaning methods. Swabs were taken from the palate investigated mycologically in order to identify the yeast colonies. No statistical relationship was found between denture stomatitis and frequency of denture brushing and denture cleaning methods. However, there was a statistically significant relationship between denture stomatitis, yeasts' presence and denture cleanliness. [source] Influence of the thickness of the resin palatal vault on the closest speaking space with complete denturesJOURNAL OF ORAL REHABILITATION, Issue 10 2001G. Schierano The closest speaking space (CSS) has been considered stable over time, and therefore useful to determine the vertical dimension of occlusion (VDO) in edentulous patients. Clemençon affirms that, in complete denture wearers, CSS is not constant but depends on the thickness of the resin palatal vault, and that is the air volume needed to pronounce words to remain constant. The aim of this study was to evaluate Clemençon hypothesis in a group of edentulous patients rehabilitated with traditional maxillary denture and mandibular implant anchored overdenture. The CSS was determined by means of a kinematics method using the Elite System® at 30, 60, 90, 180, 360 days from delivery. The CSS was assessed twice at each stage: with the unmodified denture and a second time after thickening the resin palatal vault by 2 mm with a calibrated wax layer. The CSS after thickening the resin palatal vault was wider. The wider CSS observed can be because of oro-sensory feedback excited by contact between tongue and palatal vault. As hypothesized by Clemençon thickening the resin palatal vault could be a useful procedure to increase the VDO, in cases in which it is too low from the aesthetic stand point. [source] Comparison of oral sensory function in complete denture and implant-supported prosthesis wearersJOURNAL OF ORAL REHABILITATION, Issue 3 2001Kyung-Soo Jang In order to compare the differences of part of the oral sensory functions among natural dentition, complete denture wearers and implant-supported prostheses wearers, tactile and pressure awareness was measured. Tactile sense was estimated by the thickness perception threshold between upper and lower dentition. Sensibility of pressure feeling was evaluated by threshold of lateral loading on tooth. Within this limited experiment, it could be concluded that an osseointegrated root form implant helped towards restoration of oral sensory functions. [source] A clinical diagnosis of diurnal (non-sleep) bruxism in denture wearersJOURNAL OF ORAL REHABILITATION, Issue 6 2000K. Piquero The purpose of this study was to establish a clinical method for diagnosing diurnal bruxism in denture wearers by recording masseter and anterior temporal electromygraph (EMG) activity. Seven suspected bruxists and five normal patients who wore complete dentures and/or distal extension base removable partial dentures were selected for participation. EMG activity in both the masseter and the anterior temporal muscles was recorded bilaterally during silent reading (10 min), maximal voluntary clenching (MVC), tapping in centric occlusion, lateral movements, chewing and swallowing. No significant differences of EMG activity were found between the groups during tapping, lateral movement, chewing and swallowing (P>0·05). However, during 10 min of silent reading, a significant difference was found between the groups when comparing masseter muscle activity (P<0·05). A threshold of 10% of MVC of at least 3-s duration was used to define an individual bruxism event. When the muscle activity recorded during silent reading was further analysed using these criteria, the control group displayed no bruxing activity while the suspected bruxist group displayed a mean frequency of six bruxism events (range 2,10). It was concluded that: (a) masseter muscle activity recorded during 10 min of silent reading showed significant difference between the groups; (b) the criteria selected in this study for the detection of sleep bruxism can also be used to assess diurnal bruxism; and (c) it is possible to diagnose diurnal bruxism in denture wearers by measuring the masseter EMG activity during 10 min of silent reading. [source] Reducing the Incidence of Denture Stomatitis: Are Denture Cleansers Sufficient?JOURNAL OF PROSTHODONTICS, Issue 4 2010Anto Jose MSc Abstract Purpose:,Candida albicans is the predominant oral yeast associated with denture stomatitis. With an increasing population of denture wearers, the incidence of denture stomatitis is increasing. Effective management of these patients will alleviate the morbidity associated with this disease. The aim of this study was to examine the capacity of four denture cleansers to efficiently decontaminate and sterilize surfaces covered by C. albicans biofilms. Materials and Methods: Sixteen C. albicans strains isolated from denture stomatitis patients and strain ATCC 90028 were grown as mature confluent biofilms on a 96-well format and immersed in Dentural, MedicalÔ Interporous®, Steradent Active Plus, and Boots Smile denture cleansers according to the manufacturers' instructions or overnight. The metabolic activity and biomass of the biofilms were then quantified, and scanning electron microscopy (SEM) used to examine treated biofilms. Results: Dentural was the most effective denture cleanser, reducing the biomass by greater than 90% after 20 minutes. Steradent Active plus was significantly more effective following 10-minute immersion than overnight (p < 0.001). All cleansers reduced the metabolic activity by greater than 80% following overnight immersion; however, Boots Smile exhibited significantly reduced metabolic activity following only a 15-minute immersion (p < 0.001). SEM revealed residual C. albicans material following Dentural treatment. Conclusions: This study showed that denture cleansers exhibit effective anti- C. albicans biofilm activity, both in terms of removal and disinfection; however, residual biofilm retention that could lead to regrowth and denture colonization was observed. Therefore, alternative mechanical disruptive methods are required to enhance biofilm removal. [source] Periodontitis lesions are the main source of salivary cytomegalovirusMOLECULAR ORAL MICROBIOLOGY, Issue 4 2009ahin Background:, Herpesviruses play causal or cooperative roles in childhood infections, tumorigenesis, ulcerogenesis, and periodontitis. Saliva is a common vehicle of herpesvirus horizontal transmission, but the source of salivary herpesviruses remains obscure. To evaluate the significance of periodontal disease in shedding of oral herpesviruses, this study determined the genome-copy counts of human cytomegalovirus (HCMV) and Epstein,Barr virus (EBV) in whole saliva of subjects with periodontitis, gingivitis, or no natural teeth. Methods:, Whole saliva was collected from 14 periodontitis patients, 15 gingivitis patients and 13 complete denture wearers. The study subjects were systemically healthy and had not received periodontal treatment in the past 3 months. Real-time TaqMan polymerase chain reaction was used to determine the salivary load of HCMV and EBV. Results:, Salivary HCMV was detected in seven (50%) periodontitis patients, but not in any gingivitis or edentulous subjects (P < 0.001). Salivary EBV was detected in 11 (79%) periodontitis patients, in five (33%) gingivitis patients, and in seven (54%) edentulous subjects (P = 0.076). Salivary samples showed copy counts of HCMV in the range of 3.3 × 103,4.2 × 104/ml and of EBV in the range of 3.6 × 102,1.6 × 109/ml. Conclusions:, HCMV and EBV are commonly present in the saliva of periodontitis patients. Periodontitis lesions of systemically healthy subjects seem to constitute the main origin of salivary HCMV, but do not comprise the sole source of salivary EBV. [source] Oral health disparities and food insecurity in working poor CanadiansCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 4 2009Vanessa Muirhead Abstract,,, Objectives:, This study explored oral health disparities associated with food insecurity in working poor Canadians. Methods:, We used a cross-sectional stratified study design and telephone survey methodology to obtain data from 1049 working poor persons aged between 18 and 64 years. The survey instrument contained sociodemographic items, self-reported oral health measures, access to dental care indicators (dental visiting behaviour and insurance coverage) and questions about competing financial demands. Food-insecure persons gave ,often' or ,sometimes' responses to any of the three food insecurity indicators used in the Canadian Community Health Survey (2003) assessing ,worry' about not having enough food, not eating enough food and not having the desired quality of food because of insufficient finances in the previous 12 months. Results:, Food-insecure working poor persons had poor oral health compared with food-secure working poor persons indicated by a higher percentage of denture wearers (P < 0.001) and a higher prevalence of toothache, pain and functional impacts related to chewing, speaking, sleeping and work difficulties (P < 0.001). Fewer food-insecure persons rated their oral health as good or very good (P < 0.001). Logistic regression analyses showed that oral health disparities between food-insecure and food-secure persons related to denture wearing, having a toothache, reporting poor/very poor self-rated oral health or experiencing an oral health impact persisted after adjusting for sociodemographic factors and access to dental care factors (P < 0.05). Food-insecure working poor persons reported relinquishing goods or services in order to pay for necessary dental care. Conclusions:, This study identified oral health disparities within an already marginalized group not alleviated by access to professional dental care. Working poor persons regarded professional dental care as a competing financial demand. [source] Risk indicators of edentulism, partial tooth loss and prosthetic status among black and white middle-aged and older adultsCOMMUNITY DENTISTRY AND ORAL EPIDEMIOLOGY, Issue 5 2001Teresa A. Dolan Abstract ,Objectives: To describe the prevalence and risk indicators of edentulism; to describe the frequencies of wearing removable dentures; to describe the prevalence and risk indicators of fixed prosthetic restorations; to test the hypothesis that fixed prosthetic restorations are most likely to have been placed in persons at lower risk for dental and periodontal diseases, and to test the hypothesis that, with dental disease, dental behaviors, dental attitudes and ability to afford crowns taken into account, blacks are less likely than whites to have received crowns. Methods: The Florida Dental Care Study is a cohort study of subjects 45 years old or older. A telephone screening interview was done as a first stage to identify 5254 subjects who met eligibility requirements and who self-reported whether they were edentulous. In a second stage, a subsample of dentate subjects was contacted after they completed their telephone screening interview. Of these, 873 subjects completed a baseline in-person interview and dental examination. Results: A total of 19% of first-stage subjects were edentulous. In a single multiple logistic regression, having a poorer self-rated level of general health was significantly associated with edentulism, as were being poor, older and white. Among the second-stage participants (all of whom were dentate), several prosthetic patterns were observed. For example, a total of 64% of maxillary full denture wearers reported wearing their denture all the time. Participants had also received numerous fixed prosthodontic services. The proportion of subjects with at least one crown varied widely by subject characteristics. Conclusions: A substantial percentage of non-ideal frequencies of wearing removable prostheses was reported, as were prosthesis-related soreness and broken prostheses. Although we expected and observed an association between having a fixed prosthetic crown and periodontal status, dental fillings, dental attitudes and financial resources, a residual association with race suggests that blacks are much less likely to receive prosthetic crowns. The several possible reasons for this circumstance warrant further investigation. [source] | ||||||||||
