“…The properties of the silicone and the underlying tissues should not be adversely affected by the disinfecting chemical solution. 4,[6][7][8] The increasing incidence of oral cancer is the reason for the advanced research in various maxillofacial materials. Silicone elastomers chemically termed as polydimethyl siloxane have been the material of choice.…”

Purpose: The purpose of this study is to estimate the change in color stability of maxillofacial silicon after exposing it to natural weathering and disinfection using neutral soap (shampoo).Material and Methods: 60 specimens were prepared from addition linking vinyl polydimethyl siloxane and divided into 3 groups (n=20). The specimens were then conditioned differently as follows, Group I: Dark room storage (control group); Group II: Neutral soap disinfection; Group III: Outdoor natural weathering for 2 months. The color changes of the specimens were measured using a Reflective spectrophotometer (X-Rite, model RM200QC, Neu-Isenburg, Germany) using the Commission Internationale de I'Eclairage (CIE). 5 The measurements were taken after 1 month then after two months (follow up period).Results: There was insignificance increase in color change in neutral soap (shampoo) group. There was significance increase in color change in natural weathering group. In addition, there was significance difference between groups after 1 month and two months. Conclusions:Exposure to outdoor natural weathering and the disinfection with neutral soap (shampoo) causes color alteration of the maxillofacial silicone.

“…[ 25 ] A routine mechanical washing may dissolve and dislodge color or pigment from the superficial layers of silicone prosthesis as well as abrade and roughen the material surfaces, which make the material more susceptible to microbial colonization. [ 21 26 ] An alternative option proposed for cleaning the silicone prosthesis is to immerse the material in chemical disinfectants such as oxidizing agents (sodium hypochlorite, peroxide) and non-oxidizing agents (alcohol, chlorhexidine). The chlorhexidine gluconate solution was a potent disinfectant for silicone prostheses in the previous studies.…”

A BSTRACT Aims: This in-vitro study aimed to evaluate the efficacy of lemongrass ( Cymbopogon citratus ) essential oil in eradicating Candida albicans biofilm pre-established on the maxillofacial silicone specimens. Materials and Methods: Two maxillofacial silicones, namely, MDX4-4210 and Multisil Epithetik, were used for the fabrication of 6 mm diameter disks ( n = 21 for each brand of silicone). A 48-h mature C. albicans ATCC 10231 biofilm was pre-established on sterile silicone specimen. These disks were then exposed to various concentrations of lemongrass essential oil ranging from 0.31% to 5% (v/v), 20% (v/v) nystatin, and RPMI-1640 medium for 18–20 h. After exposure, the remaining viable fungal biofilm was examined by the XTT [2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide]-reduction assay. All data were analyzed by using a regression coefficient and a post hoc Tukey HSD multiple comparisons test ( α = 0.05). Results: Different brands of silicone used for fabrication did not significantly affect the formation of mature C. albicans biofilm ( P =0.302). A 5% (v/v) lemongrass essential oil significantly eliminated fungal biofilm by approximately 95% ( P =0.031). However, less than 50% of the fungal biofilm was eliminated by the tested oil at a concentration as low as 0.31% (v/v). Furthermore, the fungicidal efficacy against C. albicans biofilm of lemongrass essential oil at 2.5% (v/v) was as potent as that of 20% (v/v) nystatin suspension ( P = 0.99). Conclusion: Lemongrass essential oil expressed fungicidal effect on C. albicans biofilm pre-established on the disks fabricated from different brands of silicone. Additionally, the fungicidal effectiveness of the oil against the mature fungal biofilm was dose-dependent.

Bu çalıĢmanın amacı farklı dezenfeksiyon iĢlemlerinin maksillofasiyal silikon elastomerin yüzey pürüzlülüğü ve renk stabilitesi üzerine etkisinin değerlendirilmesidir. Gereç ve Yöntem: Maksillofasiyal silikon (M511; Technovent) materyalinden 60 adet disk Ģeklinde (15 mm çapında 3 mm kalınlığında) örnek hazırlandı. Örnekler dezenfeksiyon iĢlemlerine göre; 1) kontrol (distile su), 2) efervesan tablet (Corega), 3) nötral sabun (Sebamed), 4) dermal dezenfektan (Biorad Derm), 5) klorheksidin glukonat (Andorex) ve 6) otoklav olmak üzere altı gruba ayrıldı (n=10). Dezenfeksiyon iĢlemi otoklav grubu hariç günde iki defa 15 gün boyunca uygulandı. otoklav grubunda ise dezenfeksiyon toplamda 3 defa yapıldı. Renk ölçümleri, dezenfeksiyon iĢlemi öncesi ve sonrasında spektrofotometre ile gerçekleĢtirildi. Renk parametreleri kaydedilerek ΔE00 değerleri hesaplandı. Yüzey pürüzlülüğü (Ra) ölçümleri ise dezenfeksiyon iĢlemi öncesi ve sonrasında profilometre cihazı ile gerçekleĢtirildi. Elde edilen veriler; tek yönlü ANOVA ve tekrarlayan ölçümler için ANOVA testleri kullanılarak istatistik olarak analiz edildi (α=0,05). Bulgular: Otoklav grubunda ΔE00 değerleri (3,79); diğer gruplardan anlamlı derecede daha yüksek bulunurken diğer gruplar arasında istatistik olarak anlamlı fark yoktur (0,92-1,37) (P>0,05). Dezenfeksiyon iĢlemi öncesi ve sonrasında yüzey pürüzlülüğü değerlendirildiğinde dezenfeksiyon sonrası kontrol, efervesan tablet, nötral sabun, ve dermal dezenfektan gruplarında yüzey pürüzlülüğü değerleri anlamlı derecede daha yüksek bulundu (P<0,05). Nötral sabun grubunun dezenfeksiyon sonrası yüzey pürüzlülüğü değeri klorheksidin glukonat ve otoklav gruplarından anlamlı derecede daha yüksek bulundu (P<0,05). Sonuç: Otoklavda yapılan dezenfeksiyon iĢleminin maksillofasiyal silikon elastomerin renk değiĢimi üzerinde önemli etkisi bulunmaktadır. Dezenfeksiyon iĢlemleri genellikle maksillofasiyal silikon elastomerin yüzey pürüzlülüğünü arttırmaktadır. Anahtar kelimeler: dezenfeksiyon; maksillofasiyal protez; renk; silikon elastomerler ABSTRACT Aim: The purpose of this study was to evaluate the effects of different disinfection procedures on the surface roughness and color stability of the maxillofacial silicone. Material and Methods: Sixty disc-shaped specimens (15 mm in diameter and 3 mm in thickness) were fabricated from a maxillofacial silicone rubber (M511; Technovent). The specimens were divided into six groups according to the disinfection procedures: 1) control (distilled water), 2) effervescent tablets (Corega), 3) neutral soap (Sebamed), 4) dermal disinfectant (Biorad Derm), 5) chlorhexidine gluconate (Andorex), and 6) autoclave (n=10). Disinfection was performed two times a day for 15 days except group autoclave. In the group autoclave disinfection was applied for three times in total. Color measurements were performed by using a spectrophotometer before and after disinfection process. Color parameters were recorded and ΔE00 values were calculated. Surface roughness (Ra) were measured before and after disinfection proces...
