“…(9,10,14,27) Storing the fl exible denture base samples in chlorhexidine and artifi cial saliva results in improving in the wettability Figure (3). These results agree with the results of AL-Nema (26) and Sharma and Vidya. (28) Sodium hypochlorite causes worsening eff ect on the wettability especially the polished surface Figure (3).…”

“…While the highest mean contact angle values were observed in polished surfaces of samples stored in sodium hypochlorite for 1-day too Figure (2). When compared this result with results of AL-Nema (26) we can fi nd that (with in the limit of this study) the wettability of fl exible denture base material was better than the wettability of visible light cured resin and it was less than the wettability of heat cured resin denture base material.…”

Aims: To evaluate wettability of flexible denture base martial after immersion in saliva, artificial saliva, chlorhexidine and sodium hypochlorite for 7 days period of time. Materials and methods: sixty rectangular shape sample of flexible denture base martial were prepared with one surface polished and another surface unpolished. These samples were stored in the previously mentioned four solutions in addition to the distilled water as a control group for 1 day and 7 days. Contact angle (parameter of wettability) were measured on both surfaces after each storage periods (1-day and 7 days). The statistical analysis to the data was performed using ANOVA and Duncan Multiple Range Test. Results: The results revealed that the wettability of unpolished flexible denture base material is significantly more than the polished surface. Sodium hypochlorite had significantly decrease the wettability of polished surfaces. Periods of storage had significant effect only on the wettability of polished surfaces rather than unpolished surfaces. Conclusions: Wettability of unpolished surface of flexible material is better than the wettability of the polished surface. The storage periods have no effect on the wettability of unpolished surface. Disinfectant solutions that have oxidizing effect (sodium hypochlorite) has a worsening effect on the wettability of flexible denture base materials.

“…The wettability on the solid surface is measured by the contact an-gleʼs meeting point at the solidairliquid, which is a widely known technique. The obtained values depend on the surface tension of the liquid, surface energy of the solid substrate, and surface topography (23,24) . As previously described, a material exhibiting a contact angle greater than 90° is considered hydrophobic, whereas a material with a value smaller than 90° is considered hy-drophilic (25) .…”

In Vitro Evaluation of the Relationship between the Surface Properties and Retention Force of Resilient Liners and Conventional Liners

Although the number of elderly people with natural teeth is increasing due to the rapid growth in the global elderly population, a significant number of elderly people exhibit edentulism (1, 2) . According to reports, 90% of Japanese people receive prosthetic dental treatment, and 88% of elderly people need dentures (3) . Additionally, the number of denture wearers is increasing with the advent of a superaged society (4) . People who wear complete dentures may have problems with retention and stability of the denture when eating, difficulty in cleaning dentures, denturerelated pain, loss of occlusal strength, and poor aesthetics. Many complete denture wearers have problems with the retention and stability of their mandibular dentures. Several reports have shown that the poor retention and stability of complete dentures are associated with patient dissatisfaction and a poor quality of life (5 -10) . Denture retention depends on the thickness of the saliva between the mucosal surface of the denture and the jaw crest. Moreover, the amount and viscosity of saliva influence the retention (11) .

Objective: Propolis is highly recommended in aphthous stomatitis, a condition that requires a proper delivery tool to achieve an efficient treatment. For this indication, a buccal patch that provides prolonged mucosal contact and protection would be beneficial. Accordingly, in this study, we designed propolis-loaded buccal patches, composed of three polymers (alginate, carboxymethylcellulose, and polyvinylpyrrolidone) of complementary properties, and the proper combination of them to produce the patch of optimum properties. Material and Method: Nine patches of different polymer ratios were prepared by casting method and evaluated by assessing their swelling, adhesion time and strength, and dissolution rate. Then the patches properties were correlated using artificial neural network analysis. Result and Discussion: The results showed that all patches were smooth, translucent, and flexible with surface pH between 6.5 and 7.4. The correlation between polymer composition and measured properties was complex and non-linear. Therefore, an artificial neural network was used to analyze these properties and optimize them. The model of this analysis provides higher weights for favorable tensile and adhesion strengths while considering swelling, rigidity, and fast dissolution rate as unfavorable. According to summation analysis, the combination of CMC% and PVP% of 15.5 and 13, respectively, provides the best score of 3.5.
