“…In 2012, Jingwei He et al incorporated quaternary ammonium salts into methyl methacrylate (MMA) to form a quaternary ammonium methacrylate that maintained its antibacterial activity without sacrificing its mechanical properties [ 90 ]. Other attempts were made to modify the surface characteristics of the materials, including electronegativity, wettability, and roughness, so as to reduce microorganism adhesion [ 91 , 92 , 93 ]. Nikawa introduced a thermocycling process to a fabricated maxillofacial prosthesis in 2001 and observed Candida albicans growing on it [ 91 ].…”

“…The results suggested that the materials exhibited antifungal effects because the surface of these materials was made hydrophobic by this method. In 2007, Khalaf modified silicone elastomer surfaces with different surface roughness and porosity and concluded that a smoother, less porous surface exhibited a lower adhesion of microorganisms [ 93 ]. It was reported that parylene coating reduced the adhesion and aggregation of C .…”

An oronasal fistula (ONF) is an abnormal structure between the oral and nasal cavities, which is a common complication of cleft palate repair due to the failure of wound healing. When some patients with ONF are unsuitable for secondary surgical repair, the obturator treatment becomes a potential method. The objectives of the obturator treatment should be summarized as filling the ONF comfortably and cosmetically restoring the dentition with partial function. The anatomy of patients with cleft palate is complex, which may lead to a more complex structure of the ONF. Thus, the manufacturing process of the obturator for these patients is more difficult. For performing the design and fabrication process rapidly and precisely, digital techniques can help, but limitations still exist. In this review, literature searches were conducted through Medline via PubMed, Wiley Online Library, Science Direct, and Web of Science, and 122 articles were selected. The purpose of this review was to introduce the development of the obturator for treating patients with ONF after cleft palate repair, from the initial achievement of the obstruction of the ONF to later problems such as fixation, velopharyngeal insufficiency, and infection, as well as the application of digital technologies in obturator manufacturing.

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...
