Does occlusal morphology of artificial teeth improve chewing of removable dentures wearers? A systematic review and meta-analysis.

This systematic review aimed to verify whether anatomic, semi-anatomic, or nonanatomic occlusal morphology of artificial teeth improves the masticatory function of complete or removable partial denture wearers. According to the PICO strategy, six databases and the grey literature were searched to identify randomized (RCT) and non-randomized clinical trials (N-RCT) comparing masticatory function, in terms of masticatory performance and efficiency, and muscle activity as primary outcomes; and patient-reported results (O) in individuals using removable dentures (P) with different occlusal morphologies of artificial teeth (I/C). Masticatory ability, satisfaction with the prosthetic treatment, and oral health-related quality of life (OHRQoL) were evaluated as secondary outcomes. Risk of bias was assessed using the Cochrane risk-of-bias tool for randomized trials (RoB 2.0) for RCT and Risk of Bias for non-randomized studies with intervention (ROBINS-I) for N-RCT studies. Meta-analyses were performed to compare primary outcomes and masticatory ability between the occlusal morphologies of artificial teeth of complete or removable partial dentures (α = 0.05). Certainty of the evidence was verified using the GRADE approach. Eleven studies (seven RCTs and four N-RCTs) were included. The risk of bias was considered low for two studies, some concerns for five, and high for the last four studies. Meta-analyses showed that removable partial dentures with anatomic artificial teeth improved masticatory efficiency for carrot chewing (MD 6.31; 95% CI [3.39, 9.22], I2 = 0%). However, masseter and temporal muscle activities increased when removable partial dentures with nonanatomic teeth were used (MD -756.97; 95% CI [-892.25, -621.68], I2 = 100%). Masticatory ability was not influenced by occlusal morphology during chewing of all foods in complete denture users: Carrot (MD -0.88, 95% CI [-8.98, 7.23], I2 = 57%); sausage (MD -8.86, 95% CI [-23.05, 5.33], I2 = 71%); apple (MD -5.78, 95% CI [-28.82, 17.26], I2 = 87%); and cheese (MD -4.16, 95% CI [-15.14, 6.82], I2 = 62%). The certainty of evidence for all evaluated outcomes was very low, mainly due to very serious problems found in the parameters of inconsistency, indirectness, and imprecision. Despite the very low certainty of evidence, the occlusal morphology of artificial teeth influences masticatory function. Anatomic teeth improved the masticatory efficiency and muscle activity of removable partial denture wearers. Nonanatomic teeth increased temporal and masseter muscle activity, which negatively affected chewing in removable partial denture users. However, patients using complete dentures with anatomic and semi-anatomic teeth presented similar masticatory ability.

Evaluation of Clinical Periodontal Parameters of Abutment Teeth Supporting Distal-Extension Base Removable Partial Dentures: A Cross-sectional Study.

To assess the clinical periodontal status of abutment teeth in regards of different design components of distal-extension removable partial dentures. Subjects (N=100) with acrylic or cobalt-chromium distal-extension removable partial dentures were enrolled and their periodontal parameters plaque and gingival indices [PI, GI], probing depths [PD], clinical attachment loss [CAL] and a mobility index [MI] evaluated. Denture base type, major connector, occlusal rests position, design of direct retainers, retention, stability and denture wearing habits were further evaluated. Acrylic RPDs were associated with higher mean±SE PI [1.70±0.74], GI [1.76±0.55], PD scores [2.47±1.02 mm] and CAL values [4.46±2.11 mm] compared to CO-CR RPDs [p⟨0.05]. For abutments, the PI [1.6±0.83], GI [1.72±0.57], PD [2.32±1.03] and CAL [4.26±2.08] were higher than their non-abutments counterparts [p⟨0.05]. CAL scores were found to be significantly higher for mandibular abutments compared to maxillary ones [P=0.002]. The highest PI [1.83±1.10] and GI [2.00±0.00] scores were associated with lingual bars and horse-shoe connectors, respectively. Full palatal coverage and lingual plates were associated with the highest PD [2.80±0.48] and CAL [4.70±0.37] scores. Acrylic RPDs, type of major connector, wrought wire clasps and distal occlusal rests may be considered as risk factors for periodontal disease progression in distal-extension removable partial denture wearers.

Assessment of Periodontal Health Among Removable and Fixed Partial Denture Wearers in Aseer Region of Saudi Arabia.

BACKGROUND Prosthetic rehabilitation will have harmful effects on periodontal structure if the patient fails to maintain an oral hygiene protocol. This study aimed to evaluate oral hygiene in fixed and removable partial denture wearers in the Aseer Province of Saudi Arabia. MATERIAL AND METHODS This was a cross-sectional study done on 286 prosthesis wearers aged between 25 and 55 years; 142 were men and 144 women. Clinical examination was done using 3 periodontal parameters: plaque index, gingival index, and calculus surface index. RESULTS It was found that 72% and 25% of patients used fixed and removable partial prostheses, respectively. Most patients were in the 45-55 year age group (38.1%), were medically fit (78%), and used toothbrush and paste (70.6%). Most patients were instructed regarding the use of oral hygiene measures for their prostheses (71.3%). However, around half of the study group (52.8%) had odor from their prostheses. Most fixed prostheses were in the posterior teeth (73.2%) and had 3 units or more (58.7%). Removable partial dentures were mostly tooth-tissue supported (74%). A statistically significant difference was found for plaque index and gingival index between natural teeth and abutments in terms of various prosthetic parameters (P£0.001). The higher prevalence of gingival inflammation, plaque, and calculus accumulation in this study may be correlated to improper oral hygiene methods used by patients. CONCLUSIONS It can be concluded that there is a need to reinforce meticulous oral hygiene practices among patients using prosthodontic appliances.

Removable partial dentures and mortality among partially edentulous adults

ObjectivesThe aim of this study was to evaluate whether the use of removable partial dentures (RPDs) has an effect on long-term survival outcomes amongst partially edentulous adults. MethodsData were extracted from the Third National Health and Nutrition Examination Survey and linked to public-use mortality files for the period up to 2019. Partially edentulous adults with fewer than 20 teeth were included. RPD use and dentition status were determined by clinical examination. The cohort was propensity score weighted to create a sample which was balanced across 27 covariates (sociodemographics, health behaviors and insurance, laboratory markers, and general health status). Survival analysis was undertaken to compute absolute (mortality rate and median survival time) and relative (event time ratio [ETR]) measures of exposure effect. ResultsThe analyzed cohort included 1246 participants, which equated to 22,557 person-years of follow-up. The difference in all-cause mortality rate between RPD wearers and non-wearers was found to be –6.5 (95% CI: –11.6 to –1.4), with the median survival time in RPD wearers being 3.1 years longer (20.3 years versus 17.2 years). A 26% increase in survival time was observed in RPD wearers (ETR: 1.26, 95% CI: 1.17 to 1.37) and it was found that, for every 7.5 individuals treated with RPDs, one death would be prevented after 10 years of treatment. ConclusionsThe use of RPDs may have long-term benefits in reducing mortality amongst adults with a non-functional dentition, but further research is needed to validate these findings and assess the factors mediating the relationship. Clinical significanceThe use of RPDs may have long-term benefits in reducing mortality amongst adults with a non-functional dentition.

An Observational Study on Oral Health and Quality of Life for RPD Wearers in the N-E Region of Romania.

There is a lack of information regarding the oral health of the elderly population in Romania; only a few articles have been published about their edentulism, and there are no official data regarding the oral health, OHRQoL, and prosthodontic status of this population. The objective of this study was to assess the relationship between the essential functional qualities of removable partial dentures (RPD) and participants’ oral-health-related wellbeing among an edentulous population from the N-E region in Romania using the OHIP-5-questionnaire. In total, 546 patients from Gr. T. Popa Iasi University were enrolled after following a set of sorting procedures. We used the Kruskal–Wallis test and the Mann–Whitney test to determine whether there were significant differences between the various groups of patients. For questions 1, 2, 3, and 5 of the OHIP, the null hypothesis was rejected, as there were statistically significant differences between the three groups. This study was limited to a specific group. However, it can provide an insight into RPD patients’ happiness when treated in an academic environment.

Assessing masticatory performance with a colour‐mixing ability test using smartphone camera images

BackgroundColour‐mixing ability tests are frequently used to assess masticatory performance, but the image acquisition process may be cumbersome and technique sensitive.ObjectivesTo evaluate the reliability of smartphone camera images in assessing masticatory performance using a colour‐mixing ability test.MethodsParticipants were recruited into three groups of dental state (n = 20 each): fully dentate, removable partial denture wearers and complete denture wearers. After performing a colour‐mixing ability test, images of the gum specimens (Hue‐Check Gum©) were captured with two smartphones and compared with the images obtained from a flatbed scanner by two examiners. The images were analysed with a subjective‐ (SA) and an opto‐electronical assessment (VoH). Inter‐ and intra‐rater reliability were tested. ANOVA models with repeated measures were used for statistical analysis (⍺ = .05).ResultsAll three image acquisition techniques were able to distinguish masticatory performance between different dental states. For SA, inter‐rater reliability was fair to substantial and intra‐rater reliability was substantial to almost perfect. For VoH, inter‐rater reliability with the smartphones was at times different between two examiners, but the intra‐rater assessment was reliable. The opto‐electronic analysis with smartphone images underestimated the masticatory performance significantly when compared to the flatbed scanner analysis. Seven‐day ageing of the specimens did not significantly affect the results.ConclusionsThe assessment of masticatory performance with the Hue‐Check Gum© is a reliable method. The use of smartphones may occasionally underestimate masticatory performance; image acquisition with a flatbed scanner remains the gold standard. A centralised analysis of the photographed wafer may foster the reliability of the diagnosis.

Effects of acrylic removable partial dentures on periodontal health of abutment teeth.

Objective: To assess the outcomes in patients wearing particularly designed acrylic removable partial dentures at different time intervals. Study Design: Descriptive Case Series Study. Setting: Department of Prosthodontics, FMH College of Dentistry, Lahore. Period: October 2017 to April, 2018. Material & Methods: Sixty five (65) abutments of acrylic removable partial denture wearers were included in the study for assessment of Mean Clinical Attachment Level (CAL), Tooth Mobility (TM) and Mean Gingival Index (GI). These periodontal parameters were clinically assessed at the day of insertion, 30th day and 60th day of insertion. Mean Clinical Attachment Level (CAL) was measured by William’s Probe. Tooth Mobility (TM) was assessed using Miller’s Classification. Gingival health was evaluated using the Gingival Index (GI) of Loe and Silness. Mean and standard deviation were calculated for patient’s age and all the periodontal scores of abutment teeth. Data was stratified for age and gender to identify the effect modifiers. Pearson chi-square test was used for Mean Gingival Index, and Mean Tooth Mobility. Post-stratification student t-test for Mean Clinical Attachment Level was used to compare the results with p ≤ 0.05 considered as significant. Results: Sstatistically insignificant results for all the periodontal parameters, i.e. the Mean Gingival Index (GI), Tooth Mobility (TM) and Mean Clinical Attachment Loss (CAL) were observed, age being not influencing the periodontal health of abutments. The only statistically significant (p= 0.01) result was observed for the Tooth Mobility (TM) in gender categories at the day of insertion and the 30th day of insertion. Conclusion: All the periodontal parameters, except tooth mobility (TM) assessed in the study, were not affected by the acrylic removable partial denture wearing.

Denture characteristics, oral hygiene practice and periodontal changes of partial denture wearers and non-denture wearers in a Teaching Hospital- A comparative study

Background: There can be localized periodontal inflammation around abutment teeth of dentures as a result of plaque accumulation. This study assessed the periodontal changes of removable partial denture wearers compared to that of non-denture wearers. Methodology: Participants were recruited from the prosthodontic and restorative outpatient clinics of Lagos University Teaching Hospital. The self-administered questionnaire was used to collect information on socio-demographics, denture characteristics, periodontal changes and oral hygiene practice of participants. Periodontal status assessed included gingival inflammation, plaque accumulation and tooth mobility. Data was analyzed using SPSS version 20 (IBM SPSS Armonk, New York) and presented as frequencies and percentages. Test for significance was done using Chi-square statistics, and the level of statistical significance was set at P < 0.05. Results: A total of 96 participants between age 16 and 74years were recruited with mean age of 40±14.5years. There were 56 females and 40 males (F:M; 1.4:1). Fifty-four denture wearers and forty-two non-denture wearers were recruited into the study. Among participants wearing partial denture, 49(90.7%) had gingival inflammation; 45(91.8%) had mild inflammation compared to 4.8% participants who are non-denture wearers. 29(53.7%) denture wearers had fair oral hygiene while most 31(73.8%) non-denture wearers had excellent oral hygiene. Abutment teeth in denture wearers had tooth recession; mostly on the upper arch and also posteriorly. Conclusion: The periodontal inflammation, tooth recession and mobility in denture wearers were worse compared to non-denture wearers. Thus, they need to be motivated for more adequate oral hygiene practices and have regular recall system to monitor their periodontal health.

Association between gonial angle on orthopantomogram and reline frequency in removable partial denture wearers.

Removable dentures are a reasonable option for prosthetic treatment. However, continuous residual ridge resorption and reline procedures are inevitable owing to the strong pressure exerted on the mucosa or inappropriate pressure distribution. This study aimed to elucidate the association between the gonial angle on orthopantomogram (GAO) with occlusal force and reline frequency in removable partial denture wearers. Participants were patients who had previously received removable partial denture treatment for a free-end defect. Age, sex, number of remaining teeth, remaining opposing teeth, and occlusal support were investigated. GAO was measured using panoramic radiographs. The mean relining interval was calculated as the mean number of days between denture insertion and the first relining or subsequent relining. The association between the mean relining interval and each factor was investigated. Sixty-five subjects (33 females) were analyzed. The median value of the mean relining interval was 533.3 days, and the median GAO was 123°. There was a significant positive correlation between the mean relining interval and GAO (rs = 0.335). The number of remaining opposing teeth and occlusal support exhibited weak negative correlations with mean relining interval (rs = -0.187 and -0.214, respectively). Multivariate analysis using a generalized linear model showed that GAO was a significant explanatory variable for the mean relining interval. Within the limitations of this study, GAO was found GAO was found to contribute to the increased frequency of relining due to ridge resorption in patients with a small GAO.

Effect of educational progressive web application on patient's oral and denture knowledge and hygiene: A randomised controlled trial.

This study aimed to evaluate the effect of a novel progressive web application (PWA) on the patient's oral and denture knowledge and hygiene. Fifty-two removable partial denture wearers were randomised to receive education using the PWA, or verbal instructions accompanied by demonstration of hygienic procedures. Changes in the participants' knowledge score, plaque index, gingival index and denture plaque was evaluated during a follow-up period of 3 months. The participants' acceptance of PWA was explored through usage logs and a feedback form. Both groups showed significant improvement in knowledge scores, oral and denture hygiene indices (p < 0.001) after education. The PWA group demonstrated significantly lower gingival index score than control (p = 0.008) at the third month review. In conclusion, there is potential of using mobile application in educating elderly patients and the PWA is a viable option for providing post-denture delivery instructions.

Factors Affecting Masticatory Satisfaction in Patients with Removable Partial Dentures.

(1) Background: The degree of satisfaction with dental treatment varies among patients, and the discrepancy may exist between the patient’s subjective evaluation and the objective assessment. Further, the optimal methods for increasing patient satisfaction with mastication remain unclear. This study aimed to identify factors affecting masticatory satisfaction in patients with removable partial dentures. (2) Methods: A total of 132 participants (71.0 ± 9.0 years) were included. Masticatory satisfaction was assessed on a visual analog scale. An oral health survey was conducted to assess the number of functional teeth, missing tooth classification: Kennedy classification, occlusal support: Eichner classification, and removable partial dentures wearing jaw. Objective masticatory performance was assessed using gummy jelly, while subjective masticatory ability was assessed using food acceptance status and oral health-related quality of life. The associations of these factors with masticatory satisfaction were assessed. (3) Results: Masticatory satisfaction among removable partial denture wearers was not significantly associated with gender, age, denture wearing jaw, Kennedy classification, and occlusal support. The degree of masticatory satisfaction was significantly greater with higher levels of masticatory function: masticatory performance, food acceptance score, and OHIP-14 score. The OHIP-14 score was the only significant explanatory variable for masticatory satisfaction in the multiple regression analysis; the strongest associations were with the “psychological discomfort” and “physical disability” subscales (p = 0.02 and p = 0.005, respectively). (4) Conclusions: Masticatory satisfaction among removable partial denture wearers was strongly associated with oral health-related quality of life, in which the ability to eat meals comfortably with removable partial dentures is the most important determinant of masticatory satisfaction.

Understanding the impact of removable partial dentures on patients' lives and their attitudes to oral care.

Introduction Due to a rising prevalence of removable partial denture (RPD) use, there is an unmet need to explore the psychological impact on patient wellbeing.Aim To assess the psychological effects of consumers losing teeth and receiving partial dentures to better manage their needs.Design Four market research surveys, undertaken on behalf of GlaxoSmithKline Consumer Healthcare, are described.Setting Surveys were conducted across the US, Japan, Malaysia, Colombia, Brazil, Poland and Italy.Materials and methods Quantitative/qualitative methods were used to gain knowledge regarding patients' experiences living with partial dentures.Results In a global market research survey involving 3,952 RPD wearers (RPDWs), 54% said that losing teeth was difficult to accept, 40% were concerned about their appearance, 32% were embarrassed about wearing dentures and 62% wished that more oral care education was available when they were younger. In another survey of >1,000 RPDWs, self-esteem was negatively impacted in 51% of respondents and 57% reported anxiety around dental visits.Conclusions Global market research confirmed that RPDWs can have emotional and practical needs that are not well understood/documented by dental healthcare professionals (HCPs). Consumer research can enhance understanding of patients' needs by dental HCPs and provide suggestions about how they may address them.

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

Statement of problemTooth 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. PurposeThe 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 methodsThe 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). ResultsThe 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. ConclusionsDespite 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.

A new masticatory performance scale to integrate food biting, comminution and mixing ability in removable partial denture wearers.

The existing masticatory performance (MP) tests cannot comprehensively evaluate objective masticatory function. We aimed to examine the construct validity and responsiveness and determine the clinically minimum important difference (MID) and related factors of a newly developed MP scale to integrate food biting, comminution and mixing ability in patients with removable partial dentures (RPDs). Masticatory performance tests using gummy jelly, peanuts and colour-changeable gum were performed before and 3months after RPD treatment in 248 partially dentate patients. A 10-point ordinal subscale was created for each MP test based on the distributions of MP values, and the three subscales were integrated into a single scale (iMP scale). We analysed the correlations between MP values and iMP scores and determined the effect size for RPD treatments and the MID on the basis of patient perception of chewing ability. iMP scores exhibited moderate correlations with the three MP values (|ρ|=0.73-0.79, p<.001) and with the change scores (|ρ| =0.61-0.64, p<.001). The mean iMP score significantly increased after RPD treatment (p<.001), and the effect size was 0.35. Of the 248 patients, 55 (22%) reported a slight improvement in chewing ability with a mean iMP score change of 2.1 points. Sex and the number of missing teeth were significantly associated with iMP scores (p<.05). The iMP scale comprehensively evaluated objective masticatory function, including food biting, comminution and mixing ability in RPD wearers, and an increase of two points on the iMP scale was considered to be the MID in RPD treatments.

Time Dependent Oral Microflora Changes in Removable Partial Denture Wearers

Background: Denture prostheses are significant interventions in oral environment for restoring lost formand function due to tooth loss. Little is known about change in microflora in removable partial denturewearers with age and time since denture delivery. Therefore, the present study was conducted to evaluateand compare the oral microbial flora pre and post insertion of removable partial denture at different timeintervals and age groups.Materials and Method: A sample of 60 patients wearing removable partial denture was included inthe study, 30 of age group 40-50 years (Group 1) and 30 of age group 50-60 years (Group 2).Sample ofunstimulated saliva was collected from the patient’s mouth from the distal most edentulous area using threesterile cotton swabs by one investigator. Colony count and identification of microorganisms was done.Results: The difference among mean colony counts between group 1 and 2 were not statistically significantat any of the three timeintervals. A statistically significant difference in colony counts was seen betweenbaseline, 1 month and 3 months in whole sample as well as both the age groups. Among various aerobicmicroorganisms, Streptococcus mitis, Diphtheroids and Candida Albicanswere the most prevailing aerobicmicro organism after 3 months of denture use, while among anaerobic organisms, Prophyromonasgingivaliswas the most prevalent microorganism after three months.Conclusion: A significant difference in colony count as well as colonizing microorganisms has been foundin the present study. This difference according to time is an important component in the affect of removablepartial denture on oral health of denture wearers. Age group was not a significant factor affecting microbialhealth in RPD wearers.

Satisfaction and Complaints of Patients with Removable Partial Dentures: In Sample at Baghdad City, Iraq

Objective: This study examined patients’ complain regarding pain on eating, esthetic and speech problemsand gag reflex with various types of removable partial dentures (RPDs).Method: The study sample included 60 RPD wearers (36 females and 24 males) aged between (25-60)years old. Sex, age, occupation, any experience with previous RPDs, and the complaint with RPDs wererecorded. Data were analyzed using Chi-square test was applied for comparison among different variablesof oral complaints related to removable prosthesis; an independent a sample t-test was utilized. A P-value &lt;0.01 was the criterion for rejection of the invalid hypothesis.Results: the results show 60 patients, 16 (47.05%) were satisfied on acrylic and14 (77.77%) were satisfiedon flexible. And 6 (75%) were satisfied on metallic. The mean level of satisfaction among the three typesof RPDs was significantly different (P &lt; 0.01). In cases satisfaction between flexible and acrylic RPDswas significantly different. But, between either metal or acrylic, or metal and flexible RPDs no significantdifferences (P &lt; 0.01) were recognized.Conclusions: Within the limitations of this study, approximately half of cases that tooka removable partialdentures treatment were satisfied with it, showing that the quality of RPDs(in Iraq/Baghdad city) wassuitable for patients. Pain in eatingis the most common complaint that shows that dental treatments withRPDs should be provided with care when patients have pain in eating.

Effect of night dentures on tooth mobility in denture wearers with sleep bruxism: A pilot randomized controlled trial.

The purpose of this study was to investigate the inhibitory effect of night denture (ND) placement on abutment tooth mobility in removable partial denture (RPD) wearers with sleep bruxism (SB). The participants were selected from RPD wearers diagnosed with SB using BiteStrip® and randomly allocated to one of the following groups: with ND placement or without ND placement (intervention or control group, respectively). The mobility of the RPD abutment tooth was measured using Periotest® at baseline (T0) and at 1 (T1), 3 (T3), and 6 months (T6). BiteStrip® scores were recorded at T0 and T6. Intragroup comparisons of the Periotest® value (PTV) were performed using analysis of covariance. Intergroup comparisons of PTV and BiteStrip® scores were performed using the linear mixed model and Wilcoxon signed-rank test, respectively. Intragroup comparisons of BiteStrip® scores were performed using the Mann-Whitney U test. At T6, the PTV in the intervention group was significantly lower than that in the control group (p=0.004). PTV was significantly lower at T6 than that at T0 in the intervention group (p=0.030), while PTV was significantly higher at T6 than that at T0 in the control group (p=0.007). There was no significant difference in the BiteStrip® score between the two groups. The BiteStrip® score at T6 was significantly lower than that at T0 only in the intervention group (p=0.011). ND placement might inhibit the increase in mobility of RPD abutment teeth and be effective in protecting them in RPD wearers with SB.

Assessment of Level of Expectation and Awareness towards Dental Implants among Complete Denture Patients and Partial Denture Prostheses Wearers

Background Among many options to replace missing teeth, dental implant is widely popular but willingness to have implant treatment and its success depends on patients' knowledge and expectations as well as the care, skill, and judgment of clinicians. Objective The main objective of this study was to assess awareness, expectation and source of information about dental implant among complete and removable partial denture wearers and to find association between them. Method A questionnaire consisting of 6 close-ended questions was used to assess the level of knowledge and awareness among patients visiting Dental Outpatient Department of Dhulikhel Hospital regarding dental implants as a treatment option for replacing missing teeth. Chi-square test was used to study the association between demographic variables and awareness about implantation. Statistical software SPSS 20.0 was used for data analysis. Result Our results revealed significant difference in age (p=0.001), education level (p=0.03) and occupation (p=0.004) in awareness of dental implant and no significant difference in gender (p=0.567), compared between complete and removable partial denture wearers. Due to lack of awareness, lower educational status and advanced age the patients responded that they "did not know " in answer to almost all the questions. Conclusion The awareness level of dental implant was low among complete and removable denture patients and this was associated with a low level of education and lack of accurate information about dental implants.

Dental Caries Prevalence among Diabetics Acrylic Partial Denture Wearer’s- A Review

Introduction: Dental caries is one of the most common oral health conditions affecting 60-90% of the population. The progression of dental caries results in tooth loss if not treated properly. Tooth loss will presumably cause functional impairment which might ultimately affect the quality of life. Removable partial denture is one of the most widely accepted means of tooth replacement. It had been noticed that removable partial dentures increased the likelihood of new or recurrent caries on remaining adjacent natural teeth. Diabetes mellitus is the most routinely encountered disease among various systemic diseases. Studies revealed that dental caries has been more prevalent and even severe in diabetic patients than nondiabetics. Aim: To assess the effect of Acrylic Removable Partial Dentures (RPD) and diabetes in prevalence of dental caries. Materials and Methods: This study was carried out in JSSDCH, JSSAHER, Mysuru, Karnataka in the year July 2017. The duration of conducting literature search was from July 2017 to Dec 2019. Individuals participating in the study should be partially edentulous and aged between 18-64 years either diabetic or nondiabetic. 69 articles were identified from searching electronic data base (Pubmed, Cochrane, Google scholar) and manual searching from July 2017 to December 2019. 19 articles were excluded following an initial screening. 50 articles were included for the further review. Scientific evidence supporting the hypothesis of the study 10 articles where five articles were review and five articles were original research. The main outcome of intervention involved both methodology and assessment tools applied by investigator to assess the effect of RPD and diabetes in terms of prevalence of dental caries. Results: Studies had shown that RPD wearers shows high caries prevalence as compared to nonwearers, Diabetic patients reported high caries prevalence compared to nondiabetic patients. This literature review states that RPD and Diabetes had an impact on prevalence of dental caries. Conclusion: The conclusion from this present review would indicates that good metabolic control in diabetic patients, periodic monitoring of the removable partial denture, oral hygiene, good RPD design framework, following post-insertion instruction of the RPD, following regular recall visits contributes towards prevention of plaque favouring inhibition of caries prevalence among diabetic and nondiabetic patients wearing RPD.
