Reçine esaslı kompozitler, reçine modifiye cam iyonomer simanlar, kompomerler, fissür örtücüler, geçici dolgu materyalleri ve sayamadığımız birçok restoratif materyalin polimerizasyonu ışık ile sağlanmaktadır. Polimerizasyonun başlaması için bir başlatıcıya ihtiyaç vardır. Bu başlatıcıya fotoinitatör denir ve bu fotoinitatörlerin aktivasyonu için de ışık kaynağı gereklidir. Kullanılan ışık kaynağının fotoinitatörlerin absorbsiyon spekturumuna uygun olması gerekmektedir. Aksi takdirde spektral uyumsuzluk meydana gelecek ve bu uyumsuzluk durumunda yeterli düzeyde aktifleşemeyen fotoinitatörler polimerizasyon sürecini tam olarak gerçekleştiremeyecektir. Bu bağlamda diş hekimlerinin kullandıkları malzemelerin içeriklerine dikkat etmeleri, üreticilerin de malzemelerine dâhil ettikleri başlatıcıları belirtmeleri oldukça önemlidir. Çünkü polimerizasyon eksikliği, yapılan restorasyonun klinik başarısını olumsuz yönde etkiler. Yetersiz polimerizasyon aşınma direncinin düşük olmasına ve restorasyonun zayıf mekaniksel özellikler göstermesine neden olmaktadır. Ayrıca monomer yapının polimer yapıya dönüşümünün tam olarak gerçekleşememesi ile birlikte artık monomer miktarında belirgin bir artışın meydana gelmesi pulpa dokusu üzerinde toksik etkilerin oluşmasına sebep olabilmektedir. Bu derleme çalışmamızda polimerizasyon sürecinden ve bu sürecin başlamasını sağlayan fotoinitatörlerden bahsedilecektir. Günümüz dolgu materyalleri içerisinde sıklıkla ihtiva eden başlatıcılardan olan kamforokinon, TPO (2,4,6-Trimethyl benzoyl diphenyl phosphine oxide), PPD (1-fenil-1,2-propandion) ve son zamanlarda yeni çıkan ve bazı ürünlerde bulunan Ivocerin®’in özellikleri anlatılacaktır.

The study was descriptive and cross-sectional, from a population of 179 preschoolers aged 3 to 5 years, from two public early childhood education institutions, and their respective parents or caregivers in the department of Cusco, Peru. We worked with the entire population that met the inclusion and exclusion criteria, seventy-four preschool children were selected for each area, deciding to have the same amount of children per group based on the smallest group. A clinical odonto-stomatological examination was carried out for oral conditions (dental caries, malocclusion, and dental trauma) according to the WHO’s criteria and a survey that was used for sociodemographic characteristics. In addition, a validated Peruvian version of the ECOHIS questionnaire was used to obtain data on the impact on quality of life. All the variables of the total and individual scores of the ECOHIS domains were analyzed individually and the Kruskal-Wallis test was used to determine the association between variables. The oral conditions prevalence in preschool children in rural areas referring to dental caries was 100% (dmft index > 6), dental trauma 10.8%, and malocclusions 60.8%; for the urban area dental caries was 93.2% (dmft index > 6), dental trauma 9.5% and malocclusions 36.5%.

Blocks (5 x 5 x 5 mm) of three 3D-printed resins (Cosmos3DTemp / Yller; Resilab3D Temp / Wilcos and SmartPrint BioTemp, / MMTech) were printed (Photon, Anycubic Technology Co.). A milled material (VitaCAD-Temp, VITA) was used as control. Half the specimens were sandblasted and the rest were untreated. Two blocks were bonded with the corresponding resin cement: PanaviaV5 (Kuraray Noritake) and RelyX Ultimate (3M Oral Care). After 24 hours, the bonded blocks were sectioned into 1 x 1 mm side sticks. Half the beams were tested for µTBS and the other half was thermocycled (5000 cycles, 30s dwell-time, 5s transfer time) before µTBS testing. A four way Generalized Linear Model (material*sandblasting*cement*aging) analysis was applied. VITA exhibited the lowest µTBS, regardless of the cement, sandblasting and thermocycling. Sandblasting significantly improved the µTBS of VIT, especially after aging, but did not improve the µTBS of 3D printed resins. Sandblasting was not beneficial for 3D printed resins, although is crucial for adhesive cementation of milled temporary resins. Airborne particle abrasion affects the integrity of 3D-printed resins, without producing a benefit on the microtensile bond strength of these materials. However, sandblasting is crucial to achieve a high bond strength on milled temporary resins.","PeriodicalId":19450,"journal":{"name":"Odovtos - International Journal of Dental Sciences","volume":"31 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2023-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86250255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
