BACKGROUND
An increase in the number of elderly edentulous patients likely leads to a greater demand for dentures and denture adhesives. As denture adhesives have both positive and negative features, dentists need to know the types of denture adhesive users to be able to provide instruction to denture wearers on how to use denture adhesives effectively. This study aims to examine the utilization of denture adhesives and associated factors.
METHODS
Seven closed-ended questionnaires were developed for a web-based survey. After that, Fisher's exact tests were performed to determine the difference in the denture adhesive usage rate by gender, type of denture, last dental visit, and smoking status. A multivariate-adjusted logistic regression analysis was performed with denture adhesive use or non-use as the dependent variable and the other items as independent variables. Next, Fisher's exact tests and a multivariate-adjusted logistic regression analysis were performed with the type of denture adhesives as the dependent variable in the same way. Statistical analyses were performed for all denture wearers, complete denture wearers, and partial denture wearers. The level of statistical significance was set at p = 0.05.
RESULTS
A total of 1470 denture wearers in Japan participated in this study. Of these, 318 used denture adhesives, while 212 (66.7%) used cream; 74 (23.3%) used home liner; 25 (7.9%) used powder; four (1.3%) used sheets; and three (0.9%) used several types. The Fisher's exact tests revealed that the ratios of using denture adhesives were significantly higher for complete denture wearers (p < 0.001), last dental visit over 1 year (p = 0.005), and smokers (p = 0.005). For partial denture wearers, the ratio was significantly higher in smokers (p = 0.262). The multivariate adjusted logistic regression revealed that denture adhesive use or non-use were significantly associated with the type of denture and smoking status in all denture wearers, and just smoking status in partial denture wearers. There were no significant results about the type of denture adhesive selection.
CONCLUSIONS
From all denture wearers, complete denture wearers and smokers are more likely to use denture adhesives. In addition, smokers significantly use denture adhesives if they are partial denture wearers.

BACKGROUND
Recently, a denture adhesive that is easy to clean and contain moisturizing ingredients have been developed for patients with dry mouth. Although the retentive force produced by conventional denture adhesives and oral moisturizers have been compared on models, no study has reported their comparison in the oral cavity. In this study, we aimed to clarify the effects of different directions of traction and loads at the time of pressure contact on the retentive force on a palatal plate made from a dentulous jaw model.
METHODS
A palatal plate was fabricated with thermoplastic resin on a dentulous jaw model, and a loop-shaped traction device was attached to the centre of the palate. The test samples were a cream-type denture adhesive, a denture adhesive for dry mouth, an oral moisturizer, and a denture moisturizer. The specimens were applied to the inner surface of the plate, which was then mounted under vertical pressure. Then, the retentive force was measured, using a digital force gauge, while the plate was pulled in different directions and with different loads.
RESULTS
No significant difference in retentive force was observed in any of the test samples when the direction of traction was between 45° and 60°. The retentive force of the denture adhesive for dry mouth was significantly higher with a direction of traction of 90° than that of 45° or 60°. The retentive force when oral moisturizer was used was significantly higher in the 90° traction direction than in the 45° direction. There was no significant difference between a force of 4.0 kgf or 5.5 kgf when using a denture adhesive for dry mouth. Comparing the four load size conditions, the larger the load, the higher was the retentive force. Similar results were obtained for the cream-type denture adhesive and denture moisturizer. Significantly higher retentive force was observed for larger loads when oral moisturizer was used.
CONCLUSIONS
The results suggest that the direction of traction and the pressure load affect the retentive force on a palatal plate.

OBJECTIVES
The opportunistic fungus Candida albicans is a component of denture plaque and is associated with denture-related stomatitis. Inter-kingdom interactions between C. albicans and bacteria exist in such multi-species biofilms, which may affect the microbial composition of the plaque. This study was performed to investigate the bacterial composition of denture plaques, and the correlation between the relative abundance of these bacteria and C. albicans.
METHODS
Thirty denture plaque and 16 dental plaque samples were collected from 18 denture wearers (mean age, 80.3 years). After DNA extraction, a meta 16S rDNA amplicon library was constructed using PCR primers targeting the V3-V4 hypervariable region of bacteria. The amplicon was evaluated by high-throughput sequencing, followed by bacterial population analysis. The concentrations of both C. albicans DNA and total bacterial DNA were determined by real-time PCR. The correlation between the relative abundance of each bacterial genus and C. albicans was analyzed through Spearman's rank correlation.
RESULTS
The genera Streptococcus, Lactobacillus, Rothia, and Corynebacterium were found to be more abundant in dentures than in dental plaques. The predominant bacteria in healthcare-associated pneumonia also inhabited denture surfaces. C. albicans was positively correlated with three acidogenic bacteria and negatively correlated with Leptotrichia and pathogens associated with periodontitis and endocarditis.
CONCLUSIONS
Dentures may be significant reservoirs of pathogens causing aspiration pneumonia. Bacteria showing negative correlation with C. albicans, such as Leptotrichia, may be useful for controlling the growth of C. albicans in antifungal therapies.

Review
Foreign body impaction in the oesophagus is a common cause of acute dysphagia. Oesophageal impaction of sharp objects such as dentures can be life threatening due to the risk of oesophageal perforation. This condition requires urgent treatment, and therefore prompt diagnosis and management is vital to avoid complications. Diagnosing oesophageal foreign body can be challenging due to its poor localising symptoms. We describe a case of an impacted denture in which considerable delays to treatment were encountered, and discuss the pitfalls and lessons learnt. This case and review of the literature draw attention to clinical assessment, investigation and treatment options for oesophageal foreign body impaction.

Comparative Study Meta-Analysis Review
OBJECTIVES
The need for denture treatment in public health will increase as the population ages. However, the impact of dentures on nutrition, particularly overdenture treatment, remains unclear although the physical and psychological effects are known. We investigated whether treatment with a mandibular implant supported overdenture improves nutrient intake and markers of nutritional status better than a conventional complete denture in edentulous patients.
DESIGN
Systematic review and meta-analysis.
METHODS
Medline, EMBASE and the Cochrane Central Register of Controlled Trials were searched for eligible studies published up to April 2016. We included studies which compared the treatment effect of an overdenture to conventional denture on nutrition, in which primary outcomes included changes in intake of macronutrients and/or micronutrients and/or indicators of nutritional status. Two reviewers independently evaluated eligible studies and assessed the risk of bias. We used a fixed effects model to estimate the weighted mean difference (WMD) and 95% CI for change in body mass index (BMI), albumin and serum vitamin B12 between overdenture and conventional denture 6 months after treatment.
RESULTS
Of 108 eligible studies, 8 studies involving 901 participants were included in the narrative appraisal. Four studies reported changes in markers of nutritional status and nutrient intake after treatment with a prosthetic, regardless of type. In a meta-analysis of 322 participants aged 65 years or older from three studies, pooled analysis suggested no significant difference in change in BMI between an overdenture and conventional denture 6 months after treatment (WMD=-0.18 kg/m(2) (95% CI -0.52 to 0.16)), and no significant difference in change in albumin or vitamin B12 between the two treatments.
CONCLUSIONS
The modifying effect of overdenture treatment on nutritional status might be limited. Further studies are needed to evaluate the effectiveness and efficacy of denture treatments.

OBJECTIVE
To improve the level of clinical diagnosis and treatment, reduce the incidence of complications, and provide the basis for clinicians to choose an appropriate treatment, this research explores the removal methods of the impacted denture in the esophagus by endoscopy.
METHODS
Based on the clinical information, treatment methods and complications of 72 patients with denture impaction in the esophagus admitted to our hospital from January 2016 to March 2021, which were divided into the group treated with painless endoscopy and the group treated with conventional endoscopy, retrospective analysis of the therapeutic effect and complications was conducted.
RESULTS
There was no statistically significant difference between the two groups in terms of denture removal rate ( > 0.05). There were statistically significant differences between the two groups in terms of operating time and incidence rates of complications during and after the procedure. The operating time of the group treated with painless endoscopy was significantly shorter than the group treated with conventional endoscopy ( < 0.05). The incidence rates of complications during and after the procedure of the group treated with painless endoscopy were significantly lower than the group treated with conventional endoscopy ( < 0.05).
CONCLUSIONS
Compared with the conventional endoscopy, painless endoscopic management of denture impaction in the esophagus under general anesthesia with tracheal intubation improves the clinical efficacy and reduces the adverse reactions. Thus, it is worthy of clinical popularization and application.

: Tooth loss and consequent denture use and impaired posture and postural balance are more prevalent in older adults than in the young ones. The aim of this cross-sectional study was to identify the association between denture use, head posture, postural balance, and neck muscle strength (NMS). : We included 107 participants (56 in the non-denture use group and 51 in the denture use group) and measured their NMS, forward head posture, and postural balance. Forward head posture was measured using the craniocervical angle (CRA). Postural balance was assessed using a timed up-and-go test (TUG) and postural sway. An independent t-test was used to analyze the differences between the groups; Pearson correlation analysis was used to analyze the correlation of period of denture use, head posture, and postural balance. : We found that the denture use group had lower NMS, smaller CRA, longer TUG, and longer postural sway length than the non-denture use group. Duration of denture use was significantly correlated with TUG. : Our findings reveal that denture use does not help with NMS, forward head maintain NMS, head posture, and postural balance in older adults.

Purpose To clarify the rate of posterior residual ridge resorption (PRRR) in different denture treatments and the factors that can affect PRRR.Study selection A bibliographical electronic search was conducted on MeSH, Web of Science, and Ovid databases. Hand searching was also conducted. Longitudinal studies recording the average rate of PRRR in the mandible were included. The effect size was calculated based on the mean rate of PRRR with standard deviation and group size. The random-effects analysis was used to perform meta-analyses across qualified studies.Results A total of 2245 eligible studies were collected from the MeSH, Web of Science, and Ovid databases and hand searching. In the end, 19 studies met the inclusion criteria and were extracted. The average rate of PRRR in different mandibular denture treatments was assessed in this systematic review. The mean combined effect size was -1.05 ± 0.5 (95% confidence interval [CI]: -3.18-1.08) between four-implant overdentures and two-implant overdentures. The combined effect size was -0.01 ± 0.22 (95% CI: -0.93-0.82) between complete dentures and two-implant overdentures. Body mass index, number of dentures used, denture wearing habit, impression technique, artificial tooth material, and peri-implant bone resorption showed no significant effect on the rate of PRRR. Gender, denture material, and relining frequency showed a significant effect on the rate of PRRR.Conclusions This review summarized different average rates of PRRR in mandibular denture treatments. Meta-analyses have reported that four-implant overdenture treatments can lower the rate of PRRR compared to two-implant overdenture treatments. However, there was no significant difference in the treatment effect between the complete denture and two-implant overdenture treatments.

Review
PURPOSE
To present a clinical rationale for the effectiveness of denture space recording methods for the prosthetic treatment of edentulous patients through a review of the literature.
STUDY SELECTION
A total of 3167 studies were extracted from a search of four terms, namely denture space, neutral zone technique, flange technique, and piezography using PubMed and J-STAGE databases. A total of 57 documents that matched the inclusion and exclusion criteria were selected.
RESULTS
From the extracted articles, the clinical application of denture space recording methods was found to be effective in edentulous patients with severe ridge resorption. The relationship between the labiolingual and buccolingual pressure in patients with neuromuscular problems or with mandibular or lingual defects differs from those without it, so a stable prosthesis can be easily fabricated by locating the neutral zone using denture space recording methods.
CONCLUSION
The literature on denture space recording methods suggests that its application on challenging cases of edentulous patients is useful in providing prostheses with improved retention and stability.

Review
AIM
Oral stereognosis is an important sensation for a human being to percept any type of materials that are introduced in the oral cavity. It is defined as the ability of an individual to recognize objects using only tactile sensation without using vision, audition, balance, somatic function, taste, or smell. The primary purpose of this review was to evaluate the effect of complete dentures on oral stereognostic ability in edentulous subjects.
SETTINGS AND DESIGN
Systematic review based on PRISMA guidelines.
MATERIALS AND METHODS
A systematic search of the electronic databases like PubMed and Web of Science was done using keywords - "stereognosis," "oral stereognosis," "complete denture," and "complete edentulism." In addition to this, a manual search of references mentioned in the articles and gray literature was done. Data extraction and assessment were done by two independent reviewers.
STATISTICAL ANALYSIS USED
Qualitative analysis.
RESULTS
The literature search yielded a total of 61 articles. Thirteen duplicate articles were removed and 36 articles were rejected after initial screening of titles and abstracts. A total of 12 articles were selected for full text reading and 5 of them were included for qualitative analysis.
CONCLUSION
All the included studies showed complete denture treatment therapy improved stereognostic ability in terms of correct identification of test pieces and time taken to identify the objects. There is also a direct relationship between the adaptability of dentures and stereognostic ability.
