“…This biomaterial is considered as a biocompatible and bioactive dentine substitute and has been indicated for coronal and radicular restorations 6) . The physical and chemical properties of CSCs can be affected by several factors such as the ratio of the constituent components, exposure to various clinical environments, storage conditions, mixing and placement technique 7,8) . Few studies have examined the effects of placement techniques on the properties of MTA-like materials [8][9][10][11][12] .…”

The purpose of this study was to evaluate the effects of ultrasonic and manual placement techniques on the push-out bond strength of Biodentine and MTA with and without calcium chloride. One hundred and twenty mid-root slices from forty freshly extracted single-rooted human mandibular premolar teeth were instrumented and randomly divided into six groups (n=20) according to the filling material and placement technique applied, as follows: G1: MTA-manual compaction, G2: Biodentine-manual compaction, G3: MTA+5% CaCl2-manual compaction, G4: MTA-ultrasonic activation, G5: Biodentine-ultrasonic activation, G6: MTA+5% CaCl2-ultrasonic activation. The push-out bond strengths were measured using an Instron testing machine. Data were analyzed using twoway analysis of variance (ANOVA) with Bonferroni correction. The ultrasonic activation significantly enhanced the bond strength values of the materials. Biodentine presented higher bond strength values than that of MTA groups. The addition of CaCl2 to MTA did not improve the bond strength of the material.

“…This causes the particles to spread out more evenly when mixed with water, and as a result less water is required to mix the cement (50). As less water is required to mix the material with water, the set product has greater compressive strength (51). A plasticiser has been included in Biodentine.…”

Objective: Under the Global Medical Device Nomenclature (GMDN) system, the newly introduced term 'hygroscopic dental cement' (HDC) encompasses MTA as well as cements based on bioceramics, calcium silicate or calcium sulphate. Many HDCs have a long history of use in dentistry. There is a need for a consistent, logical and informed approach to the nomenclature of traditional and novel HDCs. Methods: Commercial manufacturers of HDC were contacted requesting information on the compositions of products. Manufacturers that were unknown to the authors, that were unable to be contacted, that wished to be excluded from this paper, or that did not send their information on compositions in due time were not included. Results:The compositions of commercial HDCs include various hybrids of calcium silicates, calcium aluminates, calcium phosphates, calcium sulphate as well as zinc sulphates. Furthermore, there are variations in the radiopacifier as well as additives that change the handling or setting processes. Conclusion:The inclusion of different additives to HDCs enables variation in handling properties such that they now exist as distinct putties and sealers as well as cements.

ÖZETRezorpsiyon kemik, dentin ve sementin geri dönüşlü veya geri dönüşsüz kaybına sebep olan bir süreçtir. İnternal ve eksternal rezorpsiyonların tamirinde Mineral Trioksit Agregat (MTA) kullanımı yaygınlaşmaktadır. MTA ile kanal dolumu çeşitli yöntemlerle yapılmaktadır. İndirekt ultrasonik aktivasyon, MTA'nın boşluklara daha iyi dolmasını sağlayan bir metottur. Bu vaka raporunun amacı internal ve eksternal rezorpsiyon vakalarının indirekt ultrasonik aktivasyon kullanılarak MTA ile tamirinin incelenmesidir. Anahtar kelimeler: İndirekt ultrasonik aktivasyon, MTA, perforasyon, rezorpsiyon. SUMMARYResorption is a process that leads to cement, dentine and bone loss and can be reversible or irreversible. Mineral Trioxide Aggregate (MTA) has been successfully used as an obturation material in both internal and external resorption cases. There are various placement techniques for MTA. Indirect ultrasonic activation is the method of choice for cases in which fill density is an important factor. The aim of this report is to present internal and external resorption cases which were repaired with MTA using indirect ultrasonic activation.
