: Edentulism is considered to be an impediment impacting both patients' quality of life and their nutrition. Conventional complete dentures are still a preferred treatment. However, there is no consensus on the most important factors which could substantially reduce the risk of patient dissatisfaction. This study evaluated the following determinants concerning patient satisfaction with complete maxillary and mandibular dentures: sex, denture-related functional and aesthetic aspects, and the degree of bone resorption. : This study included 70 patients aged 34-81 years of age. All complete dentures were made by following the same technology. Visual analogue scales were used to assess patients' overall satisfaction with dentures, comfort, ability to speak and chew, denture aesthetics, stability, and ease of prosthesis cleaning. Satisfaction with upper and lower dentures was rated separately. The degree of bone resorption was classified by using the Kalk and de Baat (1989) method. : The mean (SD) age of the study participants was 67.3 (10.4) years; 65.7% ( = 46) were females and 34.3% ( = 24) were males. There were no significant sex-based differences in resorption of the maxilla or mandibula. There were significant differences between maxillary and mandibular dentures, with lower mean satisfaction scores concerning chewing and maxillary complete dentures, and in regard to stability and comfort for mandibular complete dentures. There was a non-significant overall lower satisfaction with increased age. In multivariate analysis for mandibular complete dentures, aesthetics and stability significantly predicted the patient's comfort levels, and the patient's comfort significantly predicted overall satisfaction. For maxillary complete dentures, patient comfort and aesthetics significantly predicted overall patient satisfaction. : Age, sex, and degree of resorption were not associated with patient satisfaction with complete dentures. Overall, patient satisfaction with both maxillary and mandibular complete dentures was related to their comfort level and denture aesthetics, and patient comfort itself was associated with stability of the mandibular denture.

Review
Tissue conditioners (TCs) are short-term soft liners, formed in situ from a mixture of a polymer powder and a liquid plasticizer. This article reviews the recent advances in the composition, functions, clinical use, gelation process, and physical properties of TCs and their effects on denture bases and oral mucosa. TCs are used to improve the fit and function of an ill-fitting denture. They can also be used to treat abused mucosal tissues underlying ill-fitting acrylic dentures as temporary expedients. TCs are recommended as provisional liners to maintain the fit of removable dentures and to prevent mechanical irritation from the denture. TCs may also be used to rehabilitate cancer patients. The polymer powder, used in the formulation of TCs generally consists of polyethyl methacrylate (PEMA) and the liquid plasticizer is ester-based in ethyl alcohol solution without an acrylic monomer. The plasticizers are low molecular weight aromatic esters. Mixing of the powder and liquid results in polymer chain entanglement and the formation of a coherent gel characterized by viscoelastic behavior appropriate to its intended clinical use. The loss of surface integrity and surface roughness of TCs are regarded as the main problems in the denture bearing oral mucosa conditions resulting in inflammation of oral mucosa of the denture-bearing area - denture stomatitis. TCs provide an even distribution of masticatory force, accurately modeling itself to the changes which occur during the healing of lesion of substrate and can act therapeutically by incorporating antifungal or antibacterial agents.

Review
To make a new complete denture, a series of steps is needed, and it is a time-consuming process. Which is not possible in every patient due to financial and medical reasons. The old denture can be relined by denture liners in less clinical and laboratory steps and can successfully increase the efficiency of ill-fitting dentures however, patient satisfaction with denture liners is doubtful. This systematic review was organized from the preferred reporting items for systematic reviews' checklist, and the methods were registered on the international prospective register of systematic reviews (PROSPERO- CRD42020210227). The main systematic review is to assess satisfaction in convectional acrylic complete denture with or without denture liners. Search engines such as PubMed, Science Direct, Cochrane, Ovid, and Google Scholar were used to extract information. The risk of bias was measured with the help of the Cochrane collaboration tool. Initially we found 1711 articles out of which 6 were finalised as per PICO criteria. Patient satisfaction was evaluated by using a visual analogue scale and questionnaire method, which shows denture liners group has more patient satisfaction. Acrylic denture liner and silicon denture liner shows better patient satisfaction compared to the conventional acrylic denture. Among denture liners, there is no significant difference.

OBJECTIVE
To investigate the tensile and flexural strength of poured, subtractive, and additive manufactured denture base methacrylates bonded to soft and hard relining materials after hydrothermal cycling and microwave irradiation.
METHODS
This study included a conventional (CB), subtractive (SB), and additive (AB) base material as well as a soft (SCR) and hard (HCR) chairside and one hard laboratory-side (HLR) relining material. Reference bodies of the base materials and bonded specimens to the relining materials were produced with a rectangular cross-section. The specimens were either pre-treated by water storage (50 h, 37 °C), hydrothermal cycling (5000 cycles, 5 °C and 55 °C, 30 s each), or microwave irradiation (6 cycles, 640 W, 3 min, wet). A tensile and four-point bending test were performed for a total of 504 specimens. Data were analysed using multivariate analysis of variance (MANOVA) with post-hoc Tukey tests (α = 0.05).
RESULTS
In comparison with the other reference groups SB showed marginally higher tensile and flexural strength (p < 0.047). Bond strength to SCR was affected neither by the base material nor by the pre-treatment (p > 0.085). HCR demonstrated twice the bond strength to AB compared with SB and CB (p ≤ 0.001). HLR showed the highest bond strength to CB (p ≤ 0.001). There was no difference between the specimens after hydrothermally cycling and microwave irradiation (p > 0.318).
SIGNIFICANCE
The bond strength of hard relining materials to subtractive and additive manufactured denture bases differ compared with conventional pouring.

INTRODUCTION
Complete dentures (CDs) have been associated with substantial problems regarding edentulous patient's function. Denture adhesives seem to be useful adjuncts to improving retention and stability.
METHODS
A clinical study was undertaken to investigate the effect of a denture adhesive (DA) on function in complete denture wearers along with the quality of their CDs. Thirty complete denture wearers participated in the study. The first phase of the experimental procedure comprised 3 groups of measurements performed at 3 distinct time points: the initial measurement (T1), a 2nd measurement after 15 days of DA daily application (T2), and a 3rd measurement following a 15-day washout period (T3). The second phase consisted of the follow-up measurements. The measurements included: recording of relative occlusal force (ROF), distribution of occlusal contacts (DOC) and center of force (COF) using the T-Scan 9.1 device and functional assessment of dentures using the FAD index.
RESULTS
The DA use induced a statistically significant increase in ROF (p-value=0.003) and decrease in COF (p-value⟨0.001) and DOC (p-value=0.001). The overall FAD score significantly improved (p-value⟨0.001).
CONCLUSIONS
The use of the DA improved the occlusal force, the distribution of occlusal contacts as well as the qualitative characteristics of CDs.

BACKGROUND
It is difficult to maintain complete dentures during meals in place. This in vitro study aimed to assess changes in denture retention between rest and function using denture adhesives and oral moisturizers in an oral cavity model.
METHODS
The following test samples were applied between the palatal plate and the edentulous jaw ridge model: denture adhesive, denture adhesive for dry mouth, oral moisturizer, and denture moisturizer. The retentive force was measured under two conditions: at rest while immersed in water and during function with a 2.5-kg load applied. The plate was pulled perpendicular to the occlusal plane and the retentive force was measured using a digital force gauge.
RESULTS
Under dry conditions, denture adhesive for dry mouth and oral moisturizer had a significantly higher retentive force than denture adhesive and denture moisturizer. After 30 min of immersion in water, the retentive force of the denture adhesive increased while that of the oral moisturizer decreased. After 30 min of function, the retentive force of the denture adhesive and denture adhesive for dry mouth remained high, while that of the oral moisturizer and denture moisturizer significantly decreased. Between rest and function, the retentive force of the denture adhesive and denture adhesive for dry mouth was high, and that of the oral moisturizer was low.
CONCLUSIONS
Immediately after use, denture adhesive for dry mouth exhibited high retentive force, but retention gradually decreased due to its water content.

In the past, our inability to cultivate most of the oral microorganisms has limited our view of this complex ecosystem. In the present study, we utilized next generation deep sequencing techniques to revisit the microbiome associated with denture malodour, a growing field with the rise in life expectancy. The study population comprised 26 full dentures patients (mean age 71 ± 6.4, 10 males, 16 females) who visited the Tel Aviv University dental geriatric clinic. Denture malodour was rated organoleptically by a single odour judge, and dentures scoring 2 and above were considered malodour positive. DNA was extracted from the swab samples and analysed using next generation deep sequencing 16 s rDNA technology. Taxa identified could be classified into nine phyla, 29 genera and 117 species. Malodour positive samples showed a higher abundance of the phyla Firmicutes and Fusobacteria and the genera Leptotrichia, Atopobium, Megasphaera, Oribacterium and Campylobacter. Microbiome analysis demonstrated higher bacterial diversity within the malodourous samples and a significant difference in the microbial profile within the two groups. Taken together these results suggest a difference between the microbial populations of malodourous and non-malodourous dentures both in composition and diversity.

Review
INTRODUCTION
Dentures are worn by 20% of the United Kingdom population for both physical and psychological symptoms associated with tooth loss. However, significant morbidity and mortality can result if dentures are swallowed or aspirated. This 10-year review investigated the development of complications following denture aspiration or ingestion, and identified key learning points.
METHODS
The Medline database was searched for cases of denture ingestion or aspiration from October 1, 2009, to October 31, 2019. Search terms included "dental prosthesis, denture, dental plate, bridge and false teeth" and "swallow, ingest, eat, aspirate and inhale." Potential factors influencing the development of complications were assessed (hollow viscus perforation, fistula formation, abscess, bowel obstruction, necrosis, hemorrhage, and airway obstruction). Statistical analysis was performed using χ and Pearson correlation tests in R Studio. No ethical approval was required.
RESULTS
Eighty-five patients were identified from 77 case reports. Fourteen articles were excluded due to insufficient information. Complications were documented in 37.6% (n = 32) of patients with 2 cases resulting in death. Duration of symptoms over 1 day ( = .005) and delayed removal beyond 4 days post-ingestion ( = .017) was significantly associated with increased rates of complications. There was no significant association between complication rate and patient age, denture type, level of impaction, or radiolucency.
CONCLUSION
Denture aspiration or ingestion can have serious consequences. Factors impacting complication rate revolve around early recognition and treatment. Clinician awareness of the potential risks of dentures is paramount to early diagnosis. We recommend early intervention to reduce the morbidity associated with this unassuming device.
