Meta-Analysis on Isolation Frequencies of Selective Pathogenic Bacteria in Complete Denture Patients

Introduction: A number of micro-organisms have been isolated from the oral cavity from dentulous patients. The chances of microorganisms to colonize complete denture surfaces as well as edentulous oral cavity are on the rise. Bacteria namely Streptococcus spp., Staphyloccus spp., Enterobacter spp., Klebsiella spp. Pseudomonas spp. and E.coli have been implicated in various cardiovascular, respiratory and gastrointestinal infections. All these bacterial spp. have been found to inhabit complete denture surfaces. Hence their isolation frequencies from complete denture have to be studied and compared by means of metaanalysis of similar studies. Methodology: Pubmed, Google Scholar, Open J Gate, Web of Science data bases were searched for relevant articles. Result: The isolation frequencies of the selective bacteria from the highest to the lowest is as follows: Streptococcus spp.(53.3%), Staphylococcus spp.(21.3), Enterobacter spp.(16.8%), Klebisella spp.(11%), Pseudomonas spp(6.1%). and E.coli (5.5%). Conclusion: Since the isolation frequencies of these bacteria are known, the appropriate disinfection methods of complete dentures targeting the various organisms have to be implemented to prevent systemic disease likely to be caused by their aspiration.

The Effect of Two Different Denture Base Materials on Retention of Complete Denture in Severely Resorbed Lower Ridge Cases

Aim of the study: to compare between two different denture base materials regarding their effect on the retention of complete dentures in patients with severely resorbed lower edentulous ridges. Material m each patient received three types of lower dentures to use it for four months, in addition to one week in between as a washing period before wearing the new one. Denture bases classified into three groups, heat cured acrylic resin denture base (Group I), heat cured acrylic resin denture base where the lower denture was lined by soft liner material (Group II) and a combination base of heat cured acrylic resin and Co-Cr denture base (Group III). Retention was evaluated after one month and three months from dentures delivery. Results: the results of this study revealed that a significant differences between group I,group II and group III denture bases during the follow up study period after one month, and non-significant differences between group I, group II and group III denture bases during the follow up study period after three months. Conclusion: from this study it is concluded that the Co-Cr denture base and Conventional heat cure acrylic resin denturebase lined with soft liner material could be used as alternative treatment modalities to conventional heat cure acrylic resin denture bases in complete edentulous cases suffering from severely resorbed lower ridges.

MEDICAL MANAGEMENT OF DENTURE STOMATITIS

ABSTRACTDenture stomatitis is a chronic inflammatory lesion which is commonly associated with Candida albicans infection. It is frequently seen in completedenture patients and clinically presented as erythema and inflammation on the palatal mucosa. This review covers the different medical managementof denture stomatitis. The first line of treatment is by topical antifungal agents, which are available as suspension, gels, lozenges, pastilles, etc. Inpatient where topical treatment was unsuccessful and in immunocompromised patient, systemic antifungal agents are prescribed. Recent studieshave shown the effectiveness of natural products such as propolis, green tea extracts, and various essential oils in the treatment of denture stomatitis,to decrease colony count and reduce erythema of palatal mucosa.Keywords: Denture stomatitis, Antifungal drugs, Propolis, Green tea, Essential oils.

Evaluation of patient experience and satisfaction with CAD-CAM-fabricated complete dentures: A retrospective survey study

Statement of problemReports of sound, evidence-based treatment outcomes of computer-aided design and computer-aided manufacture (CAD-CAM) of complete dentures (CD) are lacking in publication databases. PurposeThe purpose of this retrospective survey study was to assess patient preferences and satisfaction when treated with digitally fabricated CDs, by using a questionnaire. Material and methodsA total of 50 patients who received digital CDs were included in this study. A 10-item questionnaire was sent to the patients in order to assess their satisfaction with their digital CD experience. The items, or statements listed, were concerned with patient satisfaction and also the treatment technique and final outcome. Results of patient satisfaction questions were evaluated using descriptive statistics, means, and medians. All statistical tests were performed using commercially available software. Responses to the questionnaire provided by patients were analyzed using the Mantel-Haenszel chi-squared test (α=.05). ResultsThe questionnaire was sent to 50 patients, and the total patient response rate after treatment intervention was 38% (n=19). Data obtained from questionnaire responses revealed that patients were generally pleased and satisfied with digital CDs. The chi-squared test results revealed no statistically significant differences (P=.180) in the ratings of experienced CD wearers. However, 70% of experienced CD patients agreed that their new digital CDs were “better” than their previous set of CDs. In all categories evaluated, patients gave positive responses regarding their digital CDs. ConclusionsResults of this questionnaire-driven study suggest that ratings from experienced CD wearers rehabilitated with CAD-CAM-fabricated CDs did not differ significantly from their previous ratings of conventional CDs, but overall, their satisfaction ratings of their digital CDs tended to be positive.

Determination of the Rate of Need for Relining Complete Dentures in Patients Referring to a Department of Prosthodontics

Introduction: Complete edentulous patients are an important part of prosthodontics department referrals. After a while of prosthetic use, complications such as loosening, tissue irritation, and inefficiency in chewing or change the appearance, cause the need of reline. The purpose of present study is evaluation of complete prosthesis relining needs in patients referring to removable prosthodontics department of Tabriz dentistry faculty in 2014. Materials & Methods: This retrospective study was conducted on 96 patients that referred to removable prosthetic department in dental faculty of Tabriz by questionnaire and clinical examination. Data were analyzed in SPSS21 software. In this study, P value less than 0.05 was considered statistically significant. Results: 61.5 % of patients were men and mostly were in 51-60 years old group. 83.3% had U-shaped ridge and 16.7% had V-shaped ridge. 5.2% of patients only in upper denture and 11.5% of them only in lower denture were required to reline. Also 8.3% of patients in both upper and lower denture were needed reline.75% didn't need to denture reline. Needs to reline were more in U-shaped ridge. Conclusions: Finally, the results of statistical analysis show that there was a significant relationship between need of reline and the residual ridge but there was not a significant relationship between need of reline and gender and also the time of the prosthesis is going to delivery.

The Effect of Reading Aloud Exercises for Complete Denture Patients during the Functional Rehabilitation Period.

The focus of this study was to evaluate the effect of reading aloud on masticatory performance and patient satisfaction of patients rehabilitated with conventional complete dentures for the first time. Sixty-two edentulous patients who received conventional complete denture treatment for the first time were randomly divided into two equal groups. After insertion of the dentures, patients in group I were asked to read a news report three times per day for 4 weeks, while those in group II did not read. The reading duration increased by 5 minutes per week, from 5 minutes in the first week to 20 minutes in the fourth week. The patients' mouth opening during reading aloud was advised to gradually increase throughout the training project. Two and four weeks after insertion of the dentures, masticatory performance was assessed using the sieving method, and patient satisfaction was measured using a visual analogue scale, which combined the patient's perceptions in relation to comfort, esthetics, stability, ability to talk, and ability to chew. There were significant improvements in masticatory performance with reading aloud exercises after the insertion of complete dentures (p < 0.001) at the 2- and 4-week follow-up visits. Masticatory performance also showed significant improvement within each group in the follow-up periods (p < 0.001). No significant differences were found between the two groups in patient satisfaction (p > 0.05) at 2 weeks, but at 4 weeks, patient satisfaction regarding stability, ability to talk, and ability to chew was significantly higher for group I (p < 0.001). The results of this study suggest that reading aloud exercises significantly improved early masticatory performance and patient satisfaction for denture wearers who were treated with conventional complete dentures for the first time, and may be a useful clinical application for more effective denture treatment.

Impact of mandibular implant prostheses on the oral health-related quality of life in partially and completely edentulous patients.

To assess the oral health-related quality of life (OHRQoL) of patients provided with mandibular implant fixed partial prostheses (IFPP) for rehabilitation of two adjacent missing posterior teeth and complete denture patients provided with mandibular implant-supported overdenture (ISOD). The response to change in OHRQoL with implant prostheses was additionally compared. In this prospective study, 20 IFPP (mean age 47.0; SD 12.9years) and 28 ISOD (mean age 61.5; SD 9.1years) patients received 2 mandibular implants. Metal ceramic nonsplinted fixed prostheses were provided in IFPP group, while in ISOD group, the mandibular overdentures were retained by nonsplinted attachments. Patients rated their oral health-related quality of life using OHIP-14 Malaysian version at baseline (T0), 2-3months (T1) and 1year (T2) postimplant treatment. Mean OHIP-14 for total and domain scores between groups and intervals was analysed using repeated-measures ANOVA and t-test. Mann-Whitney and Wilcoxon signed-rank tests were used for the comparison of mean score change and effect size, while the association between pre- and post-treatment scores was determined using multivariate linear regression modelling. The total OHIP and domain scores before implant treatment were significantly higher (lower OHRQoL) in IFPP than in ISOD groups, except for physical pain where this domain showed similar impact in both groups. Postimplant scores between groups at T1 and T2 showed no significant difference. The mean score changes at T0-T1 and T0-T2 for total OHIP-14 and domains were significantly greater in IFPP except in the domains of physical pain and disability which showed no difference. Large effect size (ES) was observed for total OHIP-14 in IFPP while moderate in ISOD. Improved OHRQoL was dependent on the treatment group and pretreatment score. Improvement in OHRQoL occurred following both mandibular implant-supported overdentures and implant fixed partial prostheses.

Characterization of complete denture - 11 Case reports

Arranging the teeth for complete denture involves specific laid out principles, which are instructed in dental schools. A dentist who graduates from a dental school is expected to be sufficiently trained in the theory and the practice of teeth setting. Whether it is a conventional removable or implant retained complete denture, the principles of teeth setting remain the same. The possible effect is that all dentists may give almost identical complete dentures to their patients. The complete denture patients may be satisfied with what the dentists provides. It is the duty of the dentist to inform the patient that his or her complete dentures can be characterized to suit his/her wish and appearance better. Incorporation of correct tooth size, shade and position has a visual impact on patient's appearance. This will bring out proper harmony and balance between a persons smile and facial design. Meeting patients' expectations by giving importance to their demands is the most important criteria for success. Even though the importance should be given to the patient's choice an operator can take the liberty to arrange the teeth in an esthetic and acceptable form. This will have a positive effect on patient's self-esteem. Each complete denture patient should be evaluated individually, and the dentist should strive to make the complete denture unique to that person. The authors present 11 case reports of complete denture characterizations. Denture characterization provides infinite possibilities for the dentist.

Overdentures of the patient with Parkinson's disease: A case report

The retention of complete dentures in patients with Parkinson' s disease is often poor due to their constant dislodgement by involuntary movements of the tongue and lips. Furthermore, insertion of the overdenture is expected to be difficult due to their limited voluntary movements. This case is about the bimaxillary overdenture restoration where its retention and stability are improved, using magnetic attachment of remained roots of maxilla and two implant Locator � attachments of mandible in patients with Parkinson' s disease. This report describes the fabrication of this functionally improved prosthesis. (J Korean Acad Prosthodont 2015;53:352-8)

Relationship of the lingual frenum to the mandibular central incisors

Clinical implicationThe purpose of this study is to record the vertical distance between anterior attachment of lingual frenum and incisal edge of mandibular central incisors in dentulous subjects and then determine the mean vertical distance and to suggest guidelines for positioning of mandibular central incisors in complete dentures. MethodIn this study, 150 dentulous subjects (75 males and 75 females) were chosen based on predecided inclusion criteria. A mandibular cast was obtained from irreversible hydrocolloid impression in modified stock trays for each subject. All subjects were instructed to elevate the tongue while the impressions were made. The vertical distance between the anterior attachment of the lingual frenum and incisal edges of mandibular central incisors was measured on the casts and then the values were statistically analyzed. ResultThe distance between anterior attachment of lingual frenum (AALF) mesioincisal edge of mandibular central incisor (CI) in male, female and total (male + female) subjects was measured. In males it ranged from 7.3 to 8.9 mm with mean (±SD) 8.29 ± 0.36 mm while in females it ranged from 7.1 to 9.0 mm with mean (±SD) 8.21 ± 0.38 mm. ConclusionIt is believed that the application of this anatomic relation can provide a reliable point for arranging and checking the position of the mandibular central incisors for complete dentures in patients with class I ridge relationship.

“Utilizing the Neutral Zone: Concept and Technique for Stabilizing Complete Denture– Case Report”

The complete denture with neutral zone is not a new concept. The problem encountered with complete denture patients is the decrease in denture foundation and compromised retention. The neutral zone concept aims in the construction of complete denture using oral structure, when in function and the space available between these oral structures. This article lightness about neutral zone concept and challenges faced during the procedure of impression making by the prosthodontist, when the patient has severely resorbed ridge.

Triad treatment option to restore full mouth

The primary consideration for continued denture success with a single conventional complete denture is the preservation of that which remains in the oral cavity. The single denture is a complex prosthesis that requires a complete understanding of the basics of denture occlusion. The problems involved in providing comfort, function, proper esthetics, and retention for the maxillary complete denture patient with natural opposing dentition may be challenging. The damage to the edentulous ridge and inability to wear the denture may be avoided by good prosthetic treatment which includes adequate denture base, correct jaw relation record, and proper occlusion. In this case report, a female patient reported with generalized attrition of the remaining maxillary dentition. After clinical evaluation, taking into consideration the patient's expectations, treatment plan was decided. Using fixed, removable, and complete denture prosthesis, patients functional and esthetic requirements were fulfilled, which gave her comfort and satisfaction.

Comparison of Systemic Health Conditions between African American and Caucasian Complete Denture Patients

To compare prevalence of systemic health conditions (SHC) between African American and Caucasian edentulous patients presenting for complete dentures (CD) at an urban dental school. The study included patients presenting for CD 1/1-12/31/2010, ages 20 to 64 years, and either African American or Caucasian. Covariates included: age group, gender, employment status, Medicaid status, smoking history, and alcohol consumption. SHC included at least one of the following: arthritis, asthma, cancer, diabetes, emphysema, heart attack, heart murmur, heart surgery, hypertension, or stroke. The group (n = 88) was 44.3% African American, 65.9% ≥50, 45.5% male, 22.7% employed, and 67.0% with at least one SHC. African Americans were older (p = 0.001) and more likely to have one or more SHC (p = 0.011). Patients with at least one SHC were older (p = 0.018) and more likely female (p = 0.012). The total sample logistic regression model assessing SHC yielded only gender as statistically significant (males < OR 0.32, 95% CI 0.11 to 0.92). Caucasian males were less likely to have SHC (OR 0.17, 95% CI 0.04 to 0.77), and Caucasians ≥50 were more likely (OR 5.36, 95% CI 1.19 to 24.08). African Americans yielded no significant associations. Among selected completely edentulous denture patients at an urban dental school, two out of three patients had at least one SHC. This exploratory study suggests there may be health status differences between African American and Caucasian patients in this setting, calling for further study.

Altered taste perception among complete denture patients

Aims: The purpose of this study was to evaluate the effect of upper complete denture on gustatory sense in denture wearers. Materials and Methods: Gustatory senses in 60 subjects were evaluated with four different solutions containing sucrose, NaCl, acetic acid, and quinine dissolved in water. Means and standard deviations were calculated and then compared between the different time intervals. Results: The mean taste identification time was found to increase at compared intervals. Conclusion: Difference between mean identification times between four sessions was statistically not significant.

Influence of defective complete dentures renewal on TMD; an MRI and clinical controlled prospective study

The influence of complete denture occlusion on temporomandibular disorder (TMD) is controversial. Some studies found that defective occlusion contributes to the development of TMD, while others found no correlation. This prospective controlled study evaluated the relationship between renewal of old defective complete dentures and TMD as evidenced both by clinical examination and magnetic resonance imaging (MRI) findings. The study included 25 complete denture patients with signs and symptoms of TMD and 21 asymptomatic controls. Clicking was a common finding in all symptomatic joints. All selected participants needed complete denture renewal. MRI and clinical assessment following research diagnostic criteria for TMD guidelines (RDC/TMD) were carried out at baseline and 2 years after new complete denture insertion. Temporomandibular joint (TMJ) pain, muscle pain, clicking and movement limitation were the assessed signs and symptoms. MRIs were conducted to evaluate the TMJs for disc displacement, disc morphology and joint effusion. Complete denture renewal significantly improved the signs and symptoms of TMD in symptomatic group (p < 0.01). Only in the symptomatic group, treatment resulted in a significant increase in joints displaying superior (normal) disc position (symptomatic p < 0.001; asymptomatic p = 0.157). New dentures did not affect disc morphology in both groups (p = 0.5 for both groups) but significantly reduced joint effusion in the symptomatic group (symptomatic p < 0.001; asymptomatic p = 0.5). Relationship between clinical and MRI findings was not one to one. New complete dentures had a positive impact on TMD signs and symptoms, disc position and joint effusion but not on disc morphology.

High Performance Liquid Chromatographic Determination of Residual Monomer Released from Heat‐Cured Acrylic Resin. An In Vivo Study

Heat-polymerized acrylic resins are used in dentistry for complete denture fabrication. Despite the polymerization method, conversion of monomer into polymer is often incomplete with free or unreacted residual monomer remaining in the polymerized resin. The aim of this study was to determine the amount of residual monomeric methyl methacrylate (MMA) leaching in the saliva of patients wearing complete dentures in their postinsertion period. Thirty edentulous participants as first-time complete denture wearers (age 60 to 65 years) were selected. All the prostheses were fabricated using a similar standard technique with a heat-cured acrylic resin denture base material. Saliva samples were collected at time intervals of 1 hour, 1 day, and 3 days postdenture insertion. Participants were asked to discharge saliva every 30 seconds into a pre-weighed screw-capped container for a 5-minute period. MMA levels were measured using high performance liquid chromatography. Data were analyzed by ANOVA and Tukey-HSD. The maximum concentration of monomer released into saliva peaked 1 day after insertion of the complete dentures. The mean (SD) MMA content was 0.04 ± 0.01 (μg/ml) 1 hour after insertion, and 0.3 ± 0.09 (μg/ml), and 0.05 ± 0.01 (μg/ml) on the first and third days postinsertion, respectively. Although the released monomeric MMA was not at toxic levels, it could potentially sensitize complete denture patients or elicit an allergic reaction. The risk of the residual material as a primary irritant for a sensitizing reaction could be minimized by immersion of the denture in water for 24 hours before insertion.

Denture hygiene habits among elderly patients wearing complete dentures.

To determine the denture hygiene habits in complete denture patients according to their age and time of dentures. In this study a self administered structured was developed to know the attitude of the patients regarding denture hygiene in the department of Prosthodontics. The total study sample consisted of 230 subjects including 124 (53.9%) males and 106 (46.1%) females. Data was analyzed using SPSS version 15.0 with chi-square test at p-value <0.05. Nearly half of the subjects clean their dentures daily once. Participants from the younger age group and who had been wearing dentures since 2 years maintain better frequency of cleaning. The majority of these subjects used water and brush for denture cleansing. After seeing the condition, half of the dentures were rated as good 50.3%, followed by fair and poor as 29.5 and 20.2% respectively. Poor condition of complete dentures seen in the population is mainly due to irregularly cleansing habits and also less usage of cleansing solutions. Dentists should give proper instructions regarding maintenance of denture hygiene.

A Survey of Complete Denture Patients Experiencing Difficulties with their Prostheses

The objective of this study was to investigate the problems faced by patients having complete dentures and the cleanliness of dentures by the patients. This cross-sectional study is done with a sample of 178 patients having complete prosthesis since 1 year. A self-administered structured questionnaire pretested through a pilot survey was used in the study. The data were analyzed using the SPSS version 16.0. The Student's t-test, ANOVA and post hoc test were used as test of significance. Mastication discomfort and looseness of denture were the most common complaints followed by lack of retention (35.4%), bad breath (29.8%), tongue restriction (26.4%) and food accumulation (24.7%). There was a significant relationship of complaints with age groups (p=0.00). This study concluded that most of the patients were present with complaints due to dentures. So, dental professionals should pay serious attention to their patients for subjective acceptable result of the dentures and also advice them to properly maintain hygiene of dentures.

Comparison of Graphoanalysis with House Method in Prediction of Complete Denture Patient’s Mental Attitude: A Prospective Comparative Study

To compare and evaluate House classification and graphoanalysis for the assessment of emotional status of complete denture patients. Fifty complete denture patients were included in the study. These patients were classified according to House classification as philosophical, exacting, indifferent and hysterical based on their behaviour during the course of the complete denture fabrication. Handwriting samples of these patients were obtained independently and the patient's emotional status was again classified by graphoanalysis. Statistical analyses like Chi-square, Spearman rank correlation, and Mann-Whitney U test were used to assess the expediency of both the methods in classifying complete denture patients. A significant correlation was found between results of graphoanalysis and those of clinical experience. Chances of observing highly difficult patients like hysterical were more from graphoanalysis than by clinical experience. Graphoanalysis is a useful tool for identification of difficult patients. Classification or categorization of patients by graphoanalysis and by clinical experience of patients differs significantly and graphoanalysis when coupled with clinical experience is more helpful in identification of difficult patients than merely by clinical experience alone.

Reducing the risk of failure in complete denture patients

This paper aims to review the factors associated with an increased risk of failure in complete denture patients, based on the strength of the available evidence base. These include accuracy of jaw relations, a poorly formed mandibular ridge, poor quality dentures and patient neuroticism. Clinical strategies for overcoming these issues are described with particular reference to impression-taking and jaw relations. Identifying potential problems will help to improve outcomes for edentulous patients treated with conventional complete dentures.
