“…The contact angle of Aqwet showed low angle indicating more wettability on heat-cured polymerized acrylic resin. This result is similar to the studies conducted by Sharma and Chitre, 10 Bikash and Seema, 12 and Mohsin et al, 13 showed that Aqwet saliva substitutes containing thickening agents for increased moistening, lubrication, and longer relief of surface of the oral cavity in patients with xerostomia so it helps for the retention of the denture.…”

Aim:The aim of the present study was to evaluate the wettability of three saliva substitutes on heat-polymerized acrylic resin. Materials and methods: Heat-cured acrylic resins 150 were made and divided into three groups containing 50 samples each, i.e., group 1 Aqwet, group 2 Biotene, and group 3 Mouthkote. The prepared wax pattern was cut using 30 × 30-mm two square glass plates along the sides using a sharp carver. The uniformity of the wax samples was checked using the wax gauge. The wax samples were invested using dental plaster in varsity flasks. The samples were prepared using conventional heat-cure denture base acrylic resin. A goniometer was used to calculate receding and advancing contact angles for dynamic contact angle analysis. Results: The least mean value of advancing and receding contact angles was seen in group 1 Aqwet (68.12 ± 1.30 and 58.56 ± 0.10) followed by group 2 Biotene (81.64 ± 0.88 and 74.89 ± 0.45), and group 3 Mouthkote (85.76 ± 1.02 and 80.63 ± 0.66). A significant difference was found between the groups statistically with a p value of 0.001. A significant difference was found on multiple comparisons between group 1 vs group 3 and group 1 vs group 2 with different receding and advancing contact angles of saliva substitutes analyzed with Turkey's post hoc test. Conclusion: The lowest advancing and receding contact angle values were significantly seen in the Aqwet saliva substitute followed by Biotene and Mouthkote on heat-polymerized acrylic resin. Clinical significance: The clinical significance of the saliva substitute's good wetting property on acrylic denture base. The quality of life of the patients with xerostomia can be improved using a suitable saliva substitute.

“…Um dos critérios para avaliação do grau de umedecimento proporcionado pelas formulações de saliva é o ângulo de contato que pode sugestionar como seria a interação da saliva artificial com as superfícies da cavidade bucal ou que estão inseridas nela, como as próteses dentárias (Manosroi et al, 2020;Mohsin et al, 2017;Qureshi, 2022). Os ângulos de contato avaliados entre as soluções de inhame e os matérias avaliados (resina acrílica e Co-Cr alloy) por a Park et al (2010) foram menores que 90°.…”

A hipossalivação e xerostomia podem ser associadas à alteração dos componentes da saliva ou de sua propriedade viscoelástica geralmente com redução da mucina. Existem algumas alternativas farmacêuticas sintéticas para substituição da saliva. Porém, demonstram efeitos adversos e principalmente curta substantividade. O inhame é um tubérculo cuja mucina de sua composição parece se aproximar da mucina da saliva humana. Assim, o objetivo deste levantamento na literatura foi avaliar as propriedades reológicas e biológicas da mucilagem do inhame como uma alternativa natural de compor um substituto salivar. Foram realizadas buscas no Pubmed, Scopus, Web of Science, Lilacs, Embase, Open Gray e Google Scholar em março de 2023. O processo de seleção do estudo e de extração de dados foram realizados seguindo as diretrizes PRISMA. Os artigos incluídos nesse estudo avaliaram viscosidade, atividade da lisozima e peroxidase e ângulo de contato das soluções de inhame. Dessa forma, foram encontradas semelhanças entre as soluções de inhame com a saliva humana estimulada e não estimulada dentre as características reológicas e biológicas avaliadas, como o padrão de viscosidade e atividade enzimática.

Introduction The prevalence of adults with partially dental arches is expected to be more than imagined and patients requiring replacement of missing teeth are slowly increasing in number too. Removable partial dentures are known to provide for substantial replacement for the missing teeth with also added advantages when compared to fixed or implant prosthesis, mainly in elderly patients. Denture base material performance and durability are greatly influenced by wettability and water contact angle. In the case of dentures; adequate moisture distribution is necessary to ensure excellent wettability which has an influence on comfort and oral health. The purpose of conducting this study was to find out whether the advancements made using PEEK (Polyether ether ketone) would prove to be more beneficial than the current upgrades in the current material spectrum. Materials and methods This study was performed under in vitro conditions. All the fabrication and processing was done only by one operator. The materials used were divided into three groups each comprising 20 samples. Group A was modified polymethylmethacrylate (Bredent Polyan), Group B was polyoxymethylene acetal resin (Biodentaplast) and Group C was PEEK. An Ossila Goniometer was used to measure the contact angle. The three types of liquids used for the testing included distilled water, natural saliva and mouth wetting solution (Wet Mouth Liquid, ICPA India). Human saliva was collected from an individual with no medical conditions and normal salivary secretion. Results The data was analyzed using One-way ANOVA test and a pairwise comparison using the Post Hoc Tukey’s Honest Significant Difference. Table 1 consists of the mean water contact angles of the denture base materials and mean contact angles of various denture base materials. In saliva, mouth wetting solution and distilled water, the highest mean and least mean contact angle was seen in Polyan and Biodentaplast respectively. A signicant difference was seen between PEEK and Polyan and Biodentaplast and Polyan on further comparison. Conclusion From the resources and the materials at our disposal, it could be concluded that Polyan, Biodentaplast and PEEK and could be used as viable options in cast partial denture framework.
