Impact of Denture Use on Oral Health-Related Quality of Life in Yemeni Patients: A Cross-Sectional Analysis.

BACKGROUND We used the 14-item Oral Health Impact Profile-14 (OHIP-14) questionnaire to evaluate the association between sociodemographic variables and oral health-related quality of life in 241 wearers of removable partial or complete dentures attending a single center in Yemen. MATERIAL AND METHODS A total of 241 partial dentures (PD) and complete dentures (CD) wearers were enrolled from the Department of Prosthodontics at the Faculty of Dentistry, Sana'a University, and the University of Science and Technology. Data were collected before the commencement of denture wearing and after 3-6 months of denture use. The questionnaire consisted of sociodemographic information and denture type, and another for the OHIP to assess oral health-related quality of life (OHRQoL), oral health impact profile scale comprises 7 subscales, each evaluating different aspects of oral health and functionality. Descriptive statistics were calculated for participants. Independent t tests were performed to compare different patient groups, focusing on PD and CD wearers. Paired-sample t tests were used to examine changes within patient groups before and after removable denture use. RESULTS Among all participants, 67.6% were male, wearers of CDs were 74.6% male, PDs were 58.3%, and was consistent for CD (71.0%) and PD (72.8%) wearers. The wearing prostheses significantly impacted the OHRQoL of patients using both PDs and CDs (P<0.01). Among CD wearers, 4 of these subscales (3-6) were statistically significant, but the handicaps subscale showed evident reductions in physical pain after treatment among PD wearers. CONCLUSIONS Wearing dentures positively affects the OHRQoL of patients, influencing various aspects of their health, including functional, physical, psychological, and social well-being.

'It's like being in a tunnel': Understanding the patient journey from tooth loss to life with removable dentures.

INTRODUCTION: The aim of this study was to conceptualise the key stages of the patient journey in the provision of a new denture and examine the factors leading to successful patient-related outcomes. METHODS: Two partially dentate patient samples were included: (i) Denture wearers - patients who had a denture fitted within the previous five years and (ii) New dentures - patients receiving treatment for a new or replacement denture. The methods involved direct targeted participant observations of the denture fitting process, debriefing interviews and a follow-up focus group exploring the patient journey. Data were analysed through the use of phenomenology and grounded theory. RESULTS: Interviews were completed with twenty participants of the denture-wearing sample (11 males and nine females, age range 22 to 86 years). Thirteen participants were included in the treatment journey sample in two primary care settings (six males and seven females, age range 55 to 101 years). Tooth loss and recovery was described as being in an 'emotional tunnel' resulting from 'bodyphonic processes' associated with tooth loss. 'Bodyphonia' subsequently became the context for 'taking control' and 'managing disclosure' when living with a removable denture. Different courses through this process can be readily observed, moderated by different variables (i.e., previous experience, working knowledge, a good fit, the treatment alliance, negotiated compromises and bounded responsibility). CONCLUSIONS: An'integrating framework' that seeks to describe the patient journey from the experience of tooth loss to recovery with a denture is proposed. This framework could be used to aid development of a clinical pathway to guide treatment options. CLINICAL SIGNIFICANCE: This paper conceptualises the patient journey. It stresses the importance of understanding the stages patients go through and highlights that for the dental team, the try-in stage is perhaps the best stage to give information about the denture and plans for continued care.

HOW TO IDENTIFY SUBGROUPS IN LONGITUDINAL CLINICAL DATA: TREATMENT RESPONSE PATTERNS IN PATIENTS WITH A SHORTENED DENTAL ARCH.

BACKGROUND: When dental patients seek care, treatments are not always successful,that is patients' oral health problems are not always eliminated or substantially reduced. Identifying these patients (treatment non-responders) is essential for clinical decision-making. Group-based trajectory modeling (GBTM) is rarely used in dentistry, but a promising statistical technique to identify non-responders in particular and clinical distinct patient groups in general in longitudinal data sets. AIM: Using group-based trajectory modeling, this study aimed to demonstrate how to identify oral health-related quality of life (OHRQoL) treatment response patterns by the example of patients with a shortened dental arch (SDA). METHODS: This paper is a secondary data analysis of a randomized controlled clinical trial. In this trial SDA patients received partial removable dental prostheses replacing missing teeth up to the first molars (N = 79) either or the dental arch ended with the second premolar that was present or replaced by a cantilever fixed dental prosthesis (N = 71). Up to ten follow-up examinations (1-2, 6, 12, 24, 36, 48, 60, 96, 120, and 180 months post-treatment) continued for 15 years. The outcome OHRQoL was assessed with the 49-item Oral Health Impact Profile (OHIP). Exploratory GBTM was performed to identify treatment response patterns. RESULTS: Two response patterns could be identified - "responders" and "non-responders." Responders' OHRQoL improved substantially and stayed primarily stable over the 15 years. Non-responders' OHRQoL did not improve considerably over time or worsened. While the SDA treatments were not related to the 2 response patterns, higher levels of functional, pain-related, psychological impairment in particular, and severely impaired OHRQoL in general predicted a non-responding OHRQoL pattern after treatment. Supplementary, a 3 pattern approach has been evaluated. CONCLUSIONS: Clustering patients according to certain longitudinal characteristics after treatment is generally important, but specifically identifying treatment in non-responders is central. With the increasing availability of OHRQoL data in clinical research and regular patient care, GBTM has become a powerful tool to investigate which dental treatment works for which patients.

Impact of rehabilitation with removable complete or partial dentures on masticatory efficiency and quality of life: A cross-sectional mapping study.

STATEMENT OF PROBLEM: Tooth loss directly affects mastication, cognitive function, and oral health-related quality of life (OHRQoL). Complete dentures (CDs) and removable partial dentures (RPDs) represent a common oral rehabilitation approach. However, studies addressing the impact of removable dentures on replacing missing teeth are lacking. PURPOSE: The purpose of this clinical study was to evaluate whether the OHRQoL, the jaw function limitation (JFL), and the masticatory efficiency of CD and RPD wearers are similar to those of patients with natural teeth and to evaluate whether wearing removable dentures can predict an effect on the OHRQoL, JFL, and masticatory efficiency of their wearers. MATERIAL AND METHODS: The Oral Health Impact Profile (OHIP-14) questionnaire and the JFL scale were used to measure OHRQoL and JFL. Masticatory efficiency was analyzed by using a subjective color-mixing index for the chewing gum bolus and shape index and an objective colorimetric analysis by using a software program ViewGum. Data were analyzed with Kruskal-Wallis and post hoc Dunn tests, followed by multiple linear regression (α=.05). RESULTS: The results from OHIP-14 evidenced that both denture groups presented a low impact on OHRQoL. JFL was higher for all denture wearers. For the subjective color-mixing analysis, the control and RPD groups presented better masticatory efficiency than CD wearers. Colorimetric analysis evidenced better masticatory efficiency for the control group, who differed from the CD and RPD groups. Wearing RPDs was a predictor of impaired JFL and OHRQoL, and the use of CDs was a predictor of impaired JFL and masticatory efficiency. CONCLUSIONS: Despite being rehabilitated, CD and RPD wearers still had impaired OHRQoL, JFL, and masticatory efficiency. Also, the use of these prostheses can predict a negative effect on these 3 variables.

Quality of life related to oral health in adults with removable prosthetic rehabilitation / Calidad de vida relacionada con la salud oral en adultos con rehabilitación protésica removible

The evaluation of the oral health-related quality of life (OHRQoL) is important for clinical assessment and could be an indicator of the quality of the treatment received. Objective: To evaluate the OHRQoL in adults with removable prostheses in relation with patient characteristics such as age, sex, type and time of use of the prosthesis, previous experience and perception about the stability of the prosthesis. Materials and Methods: 217 patients from the Dental Clinic of the National University of San Marcos-Peru were evaluated after rehabilitation with a removable prosthesis. A structured questionnaire was applied by telephone interview. The evaluation of the OHRQoL was carried out using the General/Geriatric Oral Health Evaluation Index (GOHAI). For the statistical analysis, the Mann Whitney U test, the Kruskal-Wallis H test and the Spearman correlation were used. Results:The sample included 63 men (29%) and 154 women (71%) with an average age of 66.34. The average GOHAI score was 52.44+8.15. The GOHAI score was related to age (p=0.241), sex (p=0.110), type of prosthesis (p=0.069), previous experience (p=0.293), and perception of movement of the prosthesis (p<0.001). Conclusions: The GOHAI score indicates a moderate quality of life related to oral health after prosthetic rehabilitation. The GOHAI index can be considered effective for the evaluation of the OHRQoL.

La evaluación de la calidad de vida relacionada a la salud oral (CVRSO) resulta importante para la valoración clínica pudiendo ser un indicador de la calidad en el tratamiento recibido. Objetivo: Evaluar la CVRSO en adultos con rehabilitación protésica removible relacionándola con características de los participantes como edad, sexo, tipo y tiempo de uso de la prótesis, experiencia previa y percepción sobre la estabilidad de la misma. Materiales y Métodos: Se evaluaron 217 pacientes de la Clínica Odontológica de la Universidad Nacional Mayor de San Marcos-Perú, posterior a la rehabilitación con prótesis removible. Se aplicó un cuestionario estructurado mediante entrevista vía telefónica. La evaluación de la CVRSO se realizó mediante el índice de Evaluación de Salud Oral General/Geriátrica (GOHAI). Para el análisis estadístico se utilizaron las pruebas de U de Mann Whitney, H de Kruskal-Wallis y correlación de Spearman. Resultado: La muestra incluyó 63 hombres (29%) y 154 mujeres (71%) con una edad media de 66.34. La puntuación media del GOHAI fue de 52.44 + 8.15. Se relacionó la puntuación del GOHAI con la edad (p=0.241), sexo (p=0.110), tipo de prótesis (p=0.069), experiencia previa (p=0.293) y percepción de movimiento de la prótesis (p<0.001). Conclusion: La puntuación del GOHAI indica una moderada calidad de vida relacionada a la salud oral después de la rehabilitación protésica. El índice GOHAI puede considerarse efectivo para la evaluación de la CVRSO.

Impact of Removable Partial Dental Prostheses on the Oral Health-Related Quality of Life of a South African Cohort with Varied Distributions of Missing Posterior Teeth.

PURPOSE: To determine the impact of removable partial dental prostheses on satisfying the daily functioning and quality of life (QoL) of adult patients with different distributions of missing posterior teeth. MATERIALS AND METHODS: A cross-sectional interventional study was carried out on 80 patients having variously distributed posteriorly shortened and interrupted arches. Treatment comprised provision of partial dentures by senior dental students, supervised by senior clinical teachers who had knowledge of the potential benefits of the shortened dental arch (SDA) concept. The Oral Impacts on Daily Performance Index was completed before and 6 months after prosthetic treatment across groups comprising Kennedy Classes I, II, and III arches. Analysis included descriptive statistics and associations and comparisons between variables. RESULTS: Mean age of patients was 57.4 years (SD = 13.1), many were retired (72.2%), and a majority were females (60%). Most patients lived in urban areas (95%), and were largely unemployed (63.3%). At pretreatment, only 31.3% of patients reported having good dental health and satisfaction with their current oral state, while 82.5% said they had a great need for treatment. The negative oral impacts that were most frequently experienced were those of eating (67.5%), smiling (50%), and being emotionally disturbed (63.8%). Post-treatment, 76.3% indicated good oral health and satisfaction with no significant differences between the 3 Kennedy groups. Any further negative impacts were reported mostly for Kennedy Classes I and II. CONCLUSIONS: Overall, significant reductions of negative impacts were observed following treatment with dentures, across the 3 Kennedy groups, with respect to improved function, satisfaction, and oral health-related QoL. The findings confirm the reliance by partially dentate patients in all 3 Kennedy groups on dentures for improved oral health, although the possible benefits of the SDA concept as an alternative treatment option was not specifically explored.

Factors Associated with Undergoing Regular Dental Check-ups in Healthy Elderly Individuals.

The purpose of this study was to determine the distribution of healthy elderly individuals undergoing regular dental check-ups and identify any environmental or associated oral factors. A cross-sectional questionnaire survey was used to interview 216 individuals attending 2 welfare facilities for the elderly, of whom 160 were included in the final analysis. Items comprised age, sex, number of residual teeth, frequency of teeth/denture cleaning, subjective chewing ability, denture use, oral status, regular dental check-ups, visitation of the same dentist, number of dental visits in the past year, General Oral Health Assessment Index (GOHAI) (Japanese version) score, living situation, and use of routine medication. Individuals undergoing regular dental check-ups were defined as those with a primary dentist whom they saw for dental check-ups at least once a year. The rate of individuals undergoing regular dental check-ups was 75.0% in men aged 60-74 years, 58.8% in women aged 60-74 years, 70.0% in men aged 75 years or over, and 45.3% in women aged 75 years or over. Logistic regression analysis revealed a higher number of residual teeth (odds ratio [OR]=2.664 in comparison with those with fewer than 20 teeth, p=0.0427); cleaning teeth/dentures 3 or more times per day (OR=2.546 in comparison with cleaning them twice per day or less, p=0.0157); and a higher GOHAI score (OR=2.742 in comparison with those with a GOHAI score of less than 58, p=0.0263) as factors significantly correlated with undergoing regular dental check-ups. In conclusion, the results revealed that individuals undergoing regular dental check-ups had 20 or more residual teeth, cleaned their teeth/denture 3 or more times per day, and had a higher GOHAI score. This indicates that the best predictive factor for undergoing regular dental check-ups in healthy elderly individuals is their GOHAI score.

Predictors of Patient Satisfaction with Removable Denture Renewal: A Pilot Study.

PURPOSE: Conventional removable dentures still play an important role in the treatment of lost teeth. A thorough understanding of the parameters that influence patient satisfaction is useful for deciding whether denture replacement is meaningful. From a clinical perspective, factors that can be measured before starting treatment are relevant. This pilot study investigated whether patient satisfaction after denture renewal was affected by aspects related to the old prostheses, type of jaw, and patient motivation for denture renewal. MATERIALS AND METHODS: Fifty subjects (mean age 68.2 ± 8.4) were provided with 74 removable dentures (partial n = 20, complete n = 54). Satisfaction was assessed before treatment and 3 months after new prosthesis insertion. Total satisfaction 3-month post-insertion (TSP3) merged 6 individual satisfaction items measured after treatment. Change of total satisfaction 3-month post-insertion (CTS3) represented the difference of total satisfaction when old and new prostheses were compared. The effect of the following independent variables was investigated: reason patients requested new dentures (fit, esthetics, broken denture, wear, advice of dentist, extractions), satisfaction with the old prosthesis (general, retention, stability, comfort, pronunciation, chewing, esthetics), and technical quality of the old prostheses as assessed by a dentist (stability, retention, fit, border, wear, esthetics). Gender, age, and a cognitive screening test were included as confounding variables. Mann-Whitney-U tests and linear mixed model analysis were performed. RESULTS: All individual satisfaction items significantly improved with new prostheses for maxillary and mandibular jaws. TSP3 was higher for maxillary prostheses, if retention satisfaction with the old prosthesis was good, and if the dentist assessed the esthetics of the old prosthesis as deficient. CTS3 was associated with male gender, dissatisfaction with chewing before treatment, and dissatisfaction with esthetics before treatment. CONCLUSIONS: This pilot study showed that satisfaction 3 months after new denture insertion was associated with aspects of satisfaction and quality related to the old prosthesis, type of jaw, and gender. These factors may help dentists predict therapeutic benefits when deciding on the need for denture replacement. Further research should be done with a greater number of subjects and should include balanced quantities of the different types of dentures.

A short report on tooth replacement in an older suburban population in Nigeria.

OBJECTIVES: To determine: the knowledge of the participants about removable dentures, importance of tooth replacement; prevalence of tooth loss and denture use; and factors associated with its non-use among an elderly population in Nigeria. BACKGROUND: Tooth loss without replacement can impact negatively on the quality of life of the elders, thus making use of denture a basic requirement for those with partial or complete edentulous arches in developed countries. It is, however, not known if this is the case among elders in suburban Nigeria. MATERIAL AND METHODS: A cross-section of 392 consenting elderly participants aged ≥65 years residing at Idikan, Ibadan, Nigeria, were interviewed on their biodata, knowledge of removable denture and importance of tooth replacement, history of use of denture and reasons for non-use where applicable. Oral examinations for the presence of missing teeth and denture were conducted by an examiner. Data were analysed with SPSS and P value set at ˂.05. RESULTS: The mean age of the participants was 73 (SD = 9.2) years. About 39% of the participants believed that it was important to replace missing teeth, 56.0% had poor knowledge about tooth replacement options, and 47.7% had at least a missing tooth. Only 7.1% of those with missing teeth had them replaced and all were using removable acrylic partial dentures. Financial constraint was the main reason for non-replacement of missing teeth (80.1%). Age, gender, occupation before retirement, income, level of education and presence of physical impairment were associated with non-use of denture (P Ë‚ .05). CONCLUSION: Many elderly individuals had poor knowledge about removable dentures and the importance of tooth replacement. About half of the participants had full complement of teeth and only 7.1% of those with tooth loss reported denture wear. Major reasons for non-use of dentures were due to economic reasons.

Long-term follow-up indicates unimpaired oral health-related quality of life for people having shortened dental arches.

OBJECTIVES: To assess and analyse OHRQoL of people with shortened dental arches (SDA) in a long-term cohort study. METHODS: All participants of a long-term cohort study on SDA who were still attending the university dental clinic and still had an SDA (SDA group) with 3-5 posterior occluding pairs and intact anterior areas, an SDA plus removable dental prosthesis (SDA plus PRDP group) or complete dental arch (CDA group) completed the Dutch version of the Oral Health Impact Profile (OHIP-49NL) and additional questions on satisfaction with their dental status (yes/no). Mann-Whitney tests were performed for OHIP total scores and OHIP domain scores. The chance that the difference in median OHIP scores between the groups was larger than 6 OHIP units, was calculated by a bootstrapping procedure. RESULTS: 10 participants were eligible for SDA group and 11 for CDA group. The SDA plus PRDP group (n=1) was excluded from analyses. Mean follow-up period was 29.3±5.5 for SDA group and 36.7±5.5years for CDA group. Mean OHIP-49NL score was 13.9±10.9 for SDA group and 11.3±8.6 for CDA group. Differences in mean total scores and mean scores per domain were not statistically different. The probability that a difference in median OHIP total scores between groups was larger than 6 OHIP units was 0.25. Both groups showed high percentages of satisfaction with dental condition, except for dental appearance. CONCLUSION: OHRQoL of people with a long-term SDA condition was similar to that of people with CDA. CLINICAL SIGNIFICANCE: People having SDA for long periods are expected to report similar OHRQoL and satisfaction levels/oral comfort as people with CDA.

Oral health-related quality of life in patients with non-metal clasp dentures: a randomised cross-over trial.

We investigated the efficacy of non-metal clasp dentures (NMCDs) with regard to the oral health-related quality of life (OHRQoL) and compare the findings with those for conventional metal clasp-retained dentures (MCDs). This single-centre, randomised controlled, two-phase, open label, cross-over trial included 28 partially dentate individuals. The patients were randomised to receive MCDs followed by NMCDs, or the opposite sequence (n = 14 in each group); each denture was worn for 3 months. OHRQoL was evaluated using the Oral Health Impact Profile-Japanese version (OHIP-J) at entry (T-entry; before treatment with the first denture) and at 3 months after treatment with each denture (T3). An examiner evaluated denture stability, oral appearance and surface roughness before denture delivery (T0) and at T3 and denture hygiene at T3. A total of 24 patients completed the trial. There were no complications related to the dentures, abutment teeth or denture-bearing mucosa during the follow-up periods for both dentures. The mean OHIP summary score was lower for NMCDs than for MCDs, and the difference (9 points) was greater than the minimal important difference (6 points), indicating the difference was clinically relevant. The effect size was medium (0·70). Statistical analyses with linear mixed models found a significant effect of the denture type on the OHIP summary score and scores for the Oro-facial appearance, Oro-facial pain and Psychological impact domains (NMCD < MCD; P < 0·05). The results of our study suggest that NMCDs allow for better OHRQoL compared with MCDs.

Masticatory function and oral health-related quality of life in patients after partial maxillectomies with closed or open defects.

STATEMENT OF PROBLEM: The healing pattern after surgical resection of tumors of the oral cavity involving the maxilla may vary from one patient to another. The result may be open communication between the oral and nasal cavities (open defect) or complete oronasal separation after healing of the defect area (closed defect). PURPOSE: The purpose of this clinical study was to compare masticatory function and oral health-related quality of life (OHRQoL) between patients with closed and open defects who had undergone a partial maxillectomy and were wearing dentomaxillary prostheses. MATERIAL AND METHODS: Thirty-eight participants who had undergone a partial maxillectomy and who were wearing dentomaxillary prostheses were enrolled between September 2014 and April 2016. Participants were assigned to 2 groups according to the type of defect after healing: 19 participants had a closed defect, and 19 participants had an open defect. Masticatory function was evaluated objectively and subjectively. The objective measurement was food-mixing ability, which was assessed using color-changeable chewing gum. The subjective measurement was perceived mastication ability, rated as a masticatory score based on the patient's responses to a 35-item food intake questionnaire. OHRQoL was assessed using the Geriatric Oral Health Assessment Index (GOHAI). The GOHAI questionnaire consists of 12 items reflecting 3 hypothesized domains of the impact of oral disease: physical function, psychosocial function, and pain or discomfort. Differences in the scores obtained by the 3 measurements were compared between the 2 groups, using the Wilcoxon rank-sum test (α=.05). RESULTS: No significant differences were seen between the 2 groups in objective mixing ability, subjective masticatory score, or GOHAI (P>.05). Regarding the GOHAI physical function domain, only the swallowing item was significantly lower (P=.025) in participants with an open defect than in participants with a closed defect. Regarding the GOHAI psychological function domain, the item related to patients' psychological worries or concerns about their teeth, gingival tissue, or dentures was significantly lower (P=.045) in patients with an open defect than in those with a closed defect. Other items related to physical function, psychological function, and pain or discomfort were not significantly different (P>.05) between the 2 groups. CONCLUSIONS: The closed or open defect in patients who had undergone a partial maxillectomy may not influence patients' masticatory function and overall OHRQoL if they have adequate prosthetic rehabilitation. However, special consideration should be given to patients with an open defect with regard to swallowing function and psychological concerns in order to improve their OHRQoL.

Implant-supported removable partial dentures in the mandible: A 3-16 year retrospective study.

PURPOSE: The purpose of this retrospective study was to assess performance, together with biological and technical complications, of implant-supported removable partial dentures (ISRPD) in mandibular Kennedy class I situations with implants placed in the anterior or posterior position. METHODS: 23 subjects with two endosseous implants to support a bilateral-free-ending mandibular removable denture were examined. Eight subjects had implants in the premolar (anterior) region and 15 subjects implants in the molar (posterior) region. Biological and technical complications were recorded from the patients' medical record. Patients filled out a validated questionnaire regarding their appreciation of oral health related quality of life (OHIP-NL49) and a VAS score on overall satisfaction. RESULTS: Over a mean follow-up period of 8 years (median 8 years, range 3-16 years) the cumulative implant survival rate was 91.7% (SE 0.05). Mean peri-implant bone loss was 0.9mm (SD 1.0mm). Scores for bleeding on probing, plaque and mucosal health were generally low, but significantly worse for posteriorly placed implants. Significantly more biological complications occurred in the posterior group (X2(1)=3.9; p=0.048). In 65% of the cases no technical complications were registered. Mean overall OHIP score was 16.1 (SD 18.4) and patients were highly satisfied (VAS: 8.4; SD 2.1). CONCLUSIONS: Within the limitations of this retrospective study, in case of a Kennedy class I situation in the mandible, an ISRPD is a viable treatment option with a high implant survival rate and satisfied patients after a maximum of 16 years. Technical and biological complications should be anticipated. Anteriorly placed implants performed slightly better.

[Influence of the removable partial denture acrylic resin on oral health and quality of life]. / Influence de la prothèse amovible partielle en résine acrylique sur la santé bucco-dentaire et la qualité de vie.

OBJECTIVE: This study aims to evaluate dental decay incidence and DMF index, plaque index and gingival index, and to assess the satisfaction/dissatisfaction in acrylic removal partial denture wearers (ARPD) and in partial edentate no wearers. It aims to improve the therapeutic management in prosthetic oral rehabilitation in DR Congo. MATERIAL AND METHODS: This prospective cohort interventional randomized study on 376 patients enrolled and divided into two groups (with and without denture prosthesis) was performed in University Clinics of Kinshasa, Kinshasa Medical Center and Clinic Glory during the period August 2008 to August 2010. RESULTS: Three hundred seventy-six patients (376) with 163 men (47 ± 16 years) and 213 women (42 ± 15 years) were followed. Of the 376 patients randomized, 189 were of "prosthesis" group and 187 were in the group "without aid". Both groups were regularly reviewed every 6 months for 2 years. Ten thousand four hundred and fifty-two (10452) teeth were examined (5149 teeth to the group "prosthesis" and 5303 for the teeth "without prosthesis" group. On hundred and twenty-nine (129) teeth that presented caries, 110 (82.96 per cent) are decayed teeth in the "prosthesis" group and 19 (17.04 per cent) are in the group "without prosthesis" (p = 0.00). The index Tooth Decayed, Missing, Filled (CAD) to start of the study for each group was 0.2. Two years after the index rose to 0.3 for the group "prosthesis" and remained steady (0.2) for the group "without prosthesis". The "prosthesis" group showed plaque index (PI) and gingival index (GI) above 0.99 (SD: ± 0.28) and 1.27 (SD: ± 0.43) than normal compared to those of the "no aid" group (0.46 ± 0.15 and 0.32 ± 0.12). The differences were statistically significant for both indices between the two groups (p = 0.00). Overall satisfaction rate for the "prosthesis" group was 26.4% while for the group "without prosthesis" satisfaction rate is 80.9%. CONCLUSION: This study shows that improved oral hygiene and regular check of the RPD acrylic resin carriers become a concern for establishing a true oral health policy.

Oral health-related quality of life and complications after treatment with partial removable dental prosthesis.

The aims of this study were to measure and describe the oral health-related quality of life (OHRQoL) and to identify the complications caused by partial removable dental prosthesis (RDPs) in patients 1-5 years after treatment. Complications were identified in 65 patients who were treated with 83 RDPs (48 upper, 35 lower). OHRQoL was measured using the OHIP-49 before treatment and at the baseline (1-2 months after treatment) and follow-up (1-5 years after treatment) examinations. The types and numbers of oral problems that were experienced were described based on OHIP items with a score of 3 and 4. A significant improvement (P < 0·05) in the total OHIP-49 was registered from pre-treatment (mean 42, SD ± 37) to baseline (mean 29, SD ± 27) and from pre-treatment to 1-5 years after treatment (mean 32, SD ± 30). There was no significant difference between the baseline and 1- to 5-year follow-up examinations. Problems with eating and appearance registered at pre-treatment were improved at baseline and after 1-5 years. Problems with dentures that had been registered pre-treatment were improved at baseline but reoccurred after 1-5 years. The two most frequent complications were ill-fitting RDPs and inflammation of the oral mucosa, followed less frequently by fractures of the clasps. Treatment with RDPs improved OHRQoL, but denture-related problems partly remained, and new problems related to RDPs occurred 1-5 years after treatment. The two most frequent complications were ill-fitting RDPs and inflammation of the oral mucosa.

The effects of the number of natural teeth and posterior occluding pairs on the oral health-related quality of life in elderly dental patients.

OBJECTIVES: To compare between the oral health-related quality of life (OHRQoL) of Thai elderly dental patients at the Faculty of Dentistry, Chulalongkorn University with at least 20 natural teeth (NT) and those with less than 20 NT, and between those with at least 4 posterior occluding pairs (POP) and those with less than 4 POP. BACKGROUND: Thai government recommended that elderly people should have at least 20 NT and 4 POP. MATERIALS AND METHODS: The participants comprised 240 Thai elderly dental patients who were interviewed and had their OHRQoL determined using the Oral Impacts on Daily Performances Index (OIDP). Higher OIDP score indicates poorer OHRQoL. We counted the functional NT and POP in each participant. RESULTS: Participants with less than 20 NT or less than 4 POP had significantly higher OIDP scores than those with at least 20 NT or at least 4 POP. Moreover, when we evaluated one by one tooth loss, we found the first and the last significant differences between the OIDP scores in the participants with at least 23 teeth and with less than 23 teeth, and those in the participants with at least 5 teeth and with less than 5 teeth, in consequently. CONCLUSION: Thai elderly participants with at least 20 NT or at least 4 POP had greater OHRQoL than those with less than 20 NT or less than 4 POP, and in our study sample, we observed that 5 teeth may be an important clinical threshold for Thai elderly dental patients' quality of life.

Psychometric properties of the Albanian version of the Orofacial Esthetic Scale: OES-ALB.

UNLABELLED: The aim was to adapt the Orofacial Esthetic Scale (OES) and to test psychometric properties of the Albanian language version in the cultural environment of the Republic of Kosovo. METHODS: The OES questionnaire was translated from the original English version according to the accepted techniques. The reliability (internal consistency), and validity (construct, convergent and discriminative) were tested in 169 subjects, test-retest in 61 dental students (DS), and responsiveness in 51 prosthodontic patients with treatment needs (PPTN). RESULTS: The corrected item correlation coefficients of OES-ALB ranged from 0.686 to 0.909. The inter-item correlation coefficient ranged between 0.572 and 0.919. The Cronbach's alpha was 0.961 and IIC 0.758. Test- retest was confirmed by good ICCs and by no significant differences of the OES scores through the period of 14 days without any orofacial changes (p > 0.05). Construct validity was proved by the presence of one-factor composition that assumed 79.079% of the variance. Convergent validity showed significant correlation between one general question about satisfaction with orofacial esthetics and the OES summary score, as well as between the sum of the 3 OHIP-ALB49 questions related to orofacial aesthetics and the OES summary score. Discriminative validity was confirmed with statistically significant differences between DS, prosthodontic patients without treatment need and PPTN (p < 0.01). Responsiveness was confirmed by a significant increase of OES scores after PPTN patients received new fixed partial or removable dentures (P < 0.001). CONCLUSION: The results proved excellent psychometric properties of the OES-ALB questionnaire in the Republic of Kosovo.

Assessment of hygiene habits and attitudes among removable partial denture wearers in a university hospital.

AIMS: The aim of this study was conducting a survey of hygiene habits and use of removable partial dentures (RPDs) and correlate them with the social conditions of the interviewees. METHODS: A total of 145 RPD wearers were interviewed by experienced clinical staff using a structured questionnaire. A Chi-squared test was performed to evaluate statistical significance between the variables, and the level of significance was P<0.05. RESULTS: A total of 72 (49%) patients reported that they had not been well informed by the dentists. Brushing was the most frequent cleaning method (57.6%). 77 (53.1%) patients did not take off their dentures at night. The frequency of cleaning dentures and using cleansing tablet was significantly higher in females than in males (P<0.05). The frequency of denture cleaning, cleaned parts of denture, use of cleansing tablet, removal of dentures at night, frequency of tooth brushing, does not show any significant difference according to age, educational status or duration of denture usage (P>0.05). RPD wearers did not clean their dentures and natural teeth satisfactorily and had limited knowledge of denture cleansing and oral hygiene maintenance. CONCLUSIONS: Hygiene habits and attitudes may be affected by gender, but education level and hygiene attitudes may not always present positive correlation. Dentists should thoroughly inform patients about the harmful effects of overnight wearing and motivate to clean metal parts of RPD's and cleansing tablet use in order to minimize the abrasive effect of widely preferred cleaning method of brushing with toothpaste.

Effect of prosthetic restoration on oral health-related quality of life in patients with shortened dental arches: a multicentre study.

The aim of this multicentre prospective study was to investigate the effect of prosthetic restoration for missing posterior teeth in patients with shortened dental arches (SDAs). SDA patients with 2-12 missing occlusal units (a pair of occluding premolars corresponds to one unit, and a pair of occluding molars corresponds to two units) were consecutively recruited from seven university-based dental hospitals in Japan. Patients chose no replacement of missing teeth or prosthetic treatment with removable partial dentures (RPDs) or implant-supported fixed partial dentures (IFPDs). Oral health-related quality of life (OHRQoL) was measured using the oral health impact profile (Japanese version - OHIP-J) at baseline and follow-up/post-treatment evaluation. Of the 169 subjects who completed baseline evaluation, 125 subjects (mean age; 63.0 years) received follow-up/post-treatment evaluation. No-treatment was chosen by 42% (53/125) of the subjects, and 58% (72/125) chose treatment with a RPD (n = 53) or an IFPD (n = 19). In the no-treatment (NT) group, the mean OHIP summary score at baseline was similar to that at follow-up evaluation (P = 0.69). In the treatment (TRT) group, the mean OHIP summary score decreased significantly after the RPD treatment (P = 0.002), and it tended to decrease, though not statistically significant (P = 0.18), after the IFPD treatment. The restoration of one occlusal unit was associated with a 1.2-point decrease in OHIP summary score (P = 0.034). These results suggest that the replacement of missing posterior teeth with RPDs or IFPDs improved OHRQoL. Prosthetic restoration for SDAs may benefit OHRQoL in patients needing replacement of missing posterior teeth.
