RESUMO
Digital smile design (DSD) plays an essential role in the planning of aesthetic treatments. However, most digital smile designing software programmes are expensive and require specialised training and skill for effective implementation. This paper illustrates the use of Adobe Photoshop and Microsoft PowerPoint, which are economical and user friendly for planning aesthetics in a clinical case.

Aim: To evaluate and compare the flexural strength, surface roughness and porosity percentage of acrylic denture base material modiï¬ed with two antimicrobial agents, Thymoquinone (TQ) and Silver nanoparticles (AgNP). Materials and methods: A total of 90 specimens were fabricated and divided into groups A, B and C with 30 specimens each. Of the 30 specimens, 10 specimens measuring 65mmx 10mmx 2.5 mm were used to study the flexural strength, 10 specimens measuring 10 mm × 20 mm × 3 mm to study surface roughness and 10 specimens measuring 10 mm × 20 mm × 3 mm to study porosity percentage. Group A specimens were made of unmodified denture base resin, group B and C were modified with 2.5% AgNP and 1% TQ respectively. The specimens were processed in the conventional manner. A universal testing machine was used to measure flexural strength and a profilometer was used to measure surface roughness. Porosity percentage was evaluated with help of a desiccator. The data obtained was subjected to statistical analyses using One-way ANOVA and the Tukey-post hoc test, with statistical significance at p ≤ 0.05. Results: Addition of 2.5% AgNP and 1% TQ to acrylic denture base resin significantly reduced flexural strength and increased the porosity percentage (p < 0.01) but within clinically acceptable limits. No significant difference was found in the surface roughness between the various groups tested. Conclusions: Heat cured acrylic denture base resins modified with 2.5% AgNPs,1% TQ exhibited clinically acceptable flexural strength and surface properties and could be incorporated into the denture base material as an antimicrobial agent.
RESUMO
Oro-facial clefts are among the most commonly occurring congenital defects. Surgical interventions are commonly carried out to treat these deformities. Some inadequacies however, like scarring of the nasolabial complex and multiple interventions to achieve desired results still persist. Presurgical Nasoalveolar molding (PNAM) technique can be carried out before surgical repair, to facilitate a reduction in the severity of the cleft by actively molding and repositioning the clefted alveolar segments and the associated soft tissues. This case series describes the successful rehabilitation of two unilateral mid-facial cleft babies using the PNAM technique in a step wise manner with a two year follow up.
RESUMO
Background: There is generally a lack of compliance in patients who report with oral candidiasis, as they are advised to temporarily stop wearing the prosthesis and are prescribed topical antifungals which are generally unpleasant to taste and follow a rigorous schedule. Furthermore, with the alarming evidence of drug resistance, there is a need for an enhanced drug and drug delivery system. The aim of the study was to determine the dose-dependent antifungal efficacy of silver-zinc zeolite nanoparticles (SZZ-NPs) when incorporated in two brands of soft denture liners against Candida albicans. Materials and Methods: A total of 72 samples were made to determine the in vitro antifungal efficacy of SZZ-NPs and fluconazole by measuring the mean inhibition diameter (MID). Two concentrations of SZZ-NPs were compared (0.5%, 2% w/w) with fluconazole 5%w/w which is routinely prescribed. The antifungals were incorporated in two types of commercially available soft denture liners (Visco gel, GC soft denture liner). The MIDs were measured at day 1, day 7, day 15, and day 30. The values obtained (P < 0.001) were analyzed with one-way ANOVA, Tukey's post hoc, and independent t-test. Results: A statistically significant difference (P < 0.001) was noted among all the antifungal agents at all the time intervals tested. The anti-fungal efficacy of SSZ-NPs 2% w/w incorporated in GC soft denture liner was significantly superior (P < 0.001) to all groups tested and it retained its antifungal efficacy even on day 30 (MID: 18.33 ± 2.44). Conclusion: SZZ-NPs 0.5%w/w, 2%w/w, and fluconazole 5%w/w can be incorporated with soft denture liners against C. albicans. Fluconazole 5%w/w is the recommended choice for short-term antifungal efficacy, while SZZ-NPs 2%w/w is recommended when long-term antifungal efficacy is needed. GC soft denture liner was the recommended choice.
