A comparison of oral health related quality of life between complete and partial removable denture-wearing older adults in Korea

The purpose of this study was to compare the oral health related quality of life (OHRQoL) between older Korean adults with complete and partial removable dentures using oral health impact profile (OHIP). A pool of 4250 Korean older adults was identified by random stratification by area from the sample cohort of Korean National Survey of Oral Health in the year of 2000. Out of the potential pool, 445 subjects with removable partial dentures (RPDs) or complete dentures (CDs) agreed to be interviewed by telephone. Each question in the survey was about how frequently each event was experienced during the past 12 months. To analyse the association between OHIP scores and removable denture status, bivariable analysis and multiple linear regression analysis were used. RPD users showed higher scores on eight items than CD users. They were 'breath stale', 'food catching', 'sensitive teeth', 'toothache', 'tense', 'unable to brush teeth', 'less tolerant to family members' and 'irritable with others'. RPD users might be associated with higher scores of functional limitation, physical pain and psychological discomfort than CD users. RPD users had slight tendency to be associated with higher OHIP-49 score than CD users, but it was not statistically significant. The findings of the present study confirm that there is no general OHRQoL difference between RPD and CD users. But in the items and subscales of OHIP, RPD users might experience more impaired OHRQoL than CD users.     

Association of removable partial denture use with oral and systemic health

Objectives

This narrative literature review aims to consider the impact of removable partial dentures (RPDs) on oral and systemic health.

Data and sources

A review of the literature was performed using Medline/PubMed database resources up to July 2011 to identify appropriate articles that addressed the objectives of this review. This was followed by extensive hand searching using reference lists from relevant articles.

Conclusions

The proportion of partially dentate adults who wear RPDs is increasing in many populations. A major public health challenge is to plan oral healthcare for this group of patients in whom avoidance of further tooth loss is of particular importance. RPDs have the potential to negatively impact on different aspects of oral health. There is clear evidence that RPDs increase plaque and gingivitis. However, RPDs have not clearly been shown to increase the risk for periodontitis. The risk for caries, particularly root caries, appears to be higher in wearers of RPDs. Regular recall is therefore essential to minimise the risk for dental caries, as well as periodontitis. There is no evidence to support a negative impact on nutritional status, though research in this area is particularly deficient. Furthermore, there are very few studies that have investigated whether RPDs have any impact on general health. From the limited literature available, it appears that RPDs can possibly improve quality of life, and this is relevant in the era of patient-centred care. Overall, further research is required to investigate the impact of RPDs on all aspects of oral and general health, nutritional status and quality of life.     

Oral health‐related quality of life of removable partial denture wearers and related factors

This study aims to investigate the oral health‐related quality of life (OHRQoL) in a group of removable partial denture (RPD) wearers in Shiraz (Iran), using the Persian version of the Oral Health Impact Profile (OHIP‐14). Two hundred removable partial denture wearers had completed a questionnaire regarding patients' demographic characteristics and denture‐related factors. In addition, the OHIP‐14 questionnaire was filled out by interviewing the patients. Two measures of interpreting the OHIP‐14 scales were utilised: OHIP‐14 sum and OHIP‐14 prevalence. The relationship of the patients' demographic characteristics and denture‐related factors, with their OHRQoL was investigated. The mean OHIP‐14 sum and OHIP‐14 prevalence of RPD wearers were 13·80 (±10·08) and 44·5%, respectively. The most problematic aspects of OHIP‐14 were physical disability and physical pain. Twenty‐seven percentage and 24% of participants had reported meal interruption and eating discomfort, respectively. OHIP‐14 prevalence and OHIP‐14 sum were found to be significantly associated with factors representing RPD wearer's oral health such as self‐reported oral health and frequency of denture cleaning. Furthermore, OHIP‐14 prevalence and OHIP‐14 sum were significantly associated with factors related to frequency of denture use such as hours of wearing the denture during the day and wearing the denture while eating and sleeping. Therefore, it can be concluded that the OHRQoL of the patients of the study was generally not optimal and found to be strongly associated with oral health.     

Oral health-related quality of life in patients treated by implant-supported fixed dentures and removable partial dentures

Objectives: This study investigated the association between denture status [implant‐supported fixed dentures (IDs) and removable partial dentures (RPDs)] and oral health‐related quality of life (OHRQoL). Materials and methods: Consecutive patients with IDs and RPDs were recruited from the Prosthodontics Departments at Showa University and Tokyo Medical and Dental University. The Japanese version of the Oral Health Impact Profile (OHIP‐J‐49) was administered to each subject. For each OHIP‐J‐49 question, the subjects were asked to indicate the frequency with which they had experienced a dental problem during the last month. Responses were recorded on a 5 point Likert rating scale, with 0 being never and 4, very often. Summary scores were calculated and regression analyses conducted to investigate the association between denture status and OHIP‐J‐49 summary score. Results: In total 79 ID subjects (mean age±SD of 51.7±12.4 years, 44.3% men) and 109 RPD subjects (mean age of 66.5±8.6 years, 30% men) participated after giving informed consent. The regression analysis between the type of treatment and the OHIP‐J‐49 summary score revealed a significant association with a coefficient of 17.0 (Confidence interval, CI: 10.9–23.1). When age and duration of denture usage, which had significant associations with OHIP‐J‐49, were included in this model, the regression coefficient remained virtually unchanged at 17.4 (CI: 9.75–25.0), thus indicating little potential confounding by them. Conclusions: OHRQoL in patients with implant‐supported fixed dentures is generally less impaired than it is in those patients with RPDs. To cite this article :

A structural equation model relating objective and subjective masticatory function and oral health‐related quality of life in patients with removable partial dentures

Summary The aim of this study was to investigate the relationships between objective masticatory function with respect to masticatory performance and food mixing ability, patients’ perception of chewing ability and oral health‐related quality of life (OHRQoL). Partially dentate patients with removable partial dentures (n = 131, mean age 67·1 year) participated in the study. Four tests were performed to evaluate objective and subjective masticatory function and OHRQoL. Masticatory performance and food mixing ability were assessed using peanuts or a two‐coloured wax cube as test items. Patients’ perception of chewing ability was rated using a food intake questionnaire. OHRQoL was measured using the Japanese version of the oral health impact profile. A structural equation model was constructed based on hypothesis in which objective masticatory function would be related to OHRQoL via perceived chewing ability as a mediator. Structural equation modelling analysis found a statistically significant medium effect of perceived chewing ability on OHRQoL and statistically significant medium or small effects of masticatory performance on perceived chewing ability and OHRQoL (P < 0·05); however, the effect of food mixing ability on perceived chewing ability or OHRQoL was not statistically significant (P > 0·05). A fit index indicated that the model fitted well to the data (Goodness‐of‐fit index = 0·99). These results suggest that perceived chewing ability is a critical factor for OHRQoL and that masticatory performance rather than food mixing ability is important for perceived chewing ability and OHRQoL in patients with removable partial dentures.     

Investigating oral health-related quality of life and self-perceived satisfaction with partial dentures

Aim: To investigate the prevalence and severity of oral health-related quality of life in patients treated with removable partial dentures at a publicly-funded dental hospital. The association between patients' demographic profiles, denture-related, variables and oral health-related quality of life was also investigated. Methods: A questionnaire was designed to investigate the use and satisfaction of removable partial dentures, and oral health-related quality of life of removable partial denture wearers using the Oral Health Impact Profile-14. The questionnaire was administered to 740 randomly-selected patients who received removable partial dentures during 2005-2008. The response rate was 31.35%. Non-parametric tests and a logistic regression model were used to analyze the association between denture-related variables and oral health-related quality of life. A question on symptoms unrelated to dentures was also analyzed. Results: The Oral Health Impact Profile-14 prevalence calculated was 43.1%. The removable partial denture experience and frequency of use was inversely associated with Oral Health Impact Profile-14 scores. Metal-based removable partial dentures were associated with lower Oral Health Impact Profile prevalence and severity scores. No significant association was found between demographic profile, circumstance for provision of removable partial dentures and Oral Health Impact Profile-14 score. Conclusion: The participants of this study indicated that perceived denture performance, removable partial dentures material, experience, and frequency of use are associated with oral health-related quality of life.
