“…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] . Ultrasonic vibration, applied to an endodontic condenser is a placement technique to improve the flow, settling, and compaction of the material and is perceived to be a useful adjunct 9) .…”

“…Matt et al reported that apical barriers placed with ultrasonic activation demonstrated fewer voids than barriers placed without ultrasonic energy 10) . Furthermore, ultrasonic activation has been reported to enhance the surface microhardness 8) , compressive strength 11) , and sealing ability 12) of MTA. It was recently suggested that ultrasonic activation might also improve the adhesion of dental materials to the cavity walls 13) .…”

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.

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.

“…Adding greater amounts of mixing water to MTA results in lower CS, 174 increased solubility, increased porosity, 175 lower radiopacity and longer setting time. 143 Alternatively, waterless gels can be used to turn the cement into a paste, similar to the putties discussed in the section 1.2.3.4.7 on page 22.…”
