“…The long-term clinical performance of dental restorations is assessed with their ability for close adaptation to prepared cavities within tooth structure ( Van Dijken, Pallesen & Benetti, 2019 ). A broader consensus exists among the researchers on an association of marginal gap and consequent micro-leakage with the initiation of secondary caries ( Totiam et al, 2007 ; Borouziniat, Khaki & Majidinia, 2019 ). Hence, microleakage tests are employed to evaluate the effectiveness of restorations.…”

“…The phosphoric acid conditioning may lead to diminished hydroxyapatite from the etched dentin surface at the root surface area. Consequently, it could cause the depletion of the ionic bond between the carboxyl group of RMGI and composite with hydroxyapatite ( Borouziniat, Khaki & Majidinia, 2019 ). The authors suggest the utilization of a Nano-hybrid composite along with metal and teeth conditionings to restore secondary caries at indirect restoration margins.…”

Background An occurrence of secondary caries around the indirect restoration margin is reported to remain a leading cause of failures. Objective This study aimed to test the interfacial microleakage of conventional glass-ionomer (CGI), resin-modified glass ionomer (RMGI) and Nano-hybrid composite (CR) restorations at a full veneer margin crown. Methods Ninety human extracted molar teeth were divided into three groups (n = 30). Each group was subdivided into three subgroups (n = 10) according to the extent of the structural defects; The structural defect in G1 had a depth of 1.5 mm, width and length at 2 mm and 1 mm intrusion within the crown cervical margin. The corresponding structural defect dimension values for G2 were 2, 5, 4 and 2 mm with defects extending onto the root structure. Meanwhile, G3: structural deficiency of 2 mm depth, 3 mm width and 3 mm length and with 1.5 mm extension into the prepared teeth. These structural defects in each subgroup were restored with CGI, RMGI and CR. Artificial carious lesion formation was induced at the cervical finish line with a demineralizing solution. The artificial carious lesions were restored as per the group distribution. Subsequently, teeth samples were prepared and cemented with Nickel-chromium full coverage restorations utilizing glass-ionomer luting cement. Teeth samples were thermocycled, isolated with nail varnish, and immersed in 0.1% methylene blue for 24 h. The teeth samples were sectioned longitudinally, dye penetration was evaluated with a stereomicroscope. The data were analyzed with Kruskal–Wallis and Mann–Whitney U tests. Results CGI-G1 recorded the highest micro-leakage score at 1.450; while CR-G3 recorded the least score (0.350). At a cementum-restoration interface, CR-G1 (0.850) documented the lowest micro-leakage; RMGI-G3 had a greater value at 1.700. Conclusions The hybrid CR could be effectively used to restore the restoration of a marginal gap around crown margins.

Kompozit rezinlerin 1962 yılında Bowen tarafından tanıtılmalarıyla başlayan süreçte, hastaların estetik beklentisinin artması ve amalgam hakkındaki endişeler kompozit rezinleri tercih edilen materyal haline getirmiştir. Kompozit rezinlerin estetik olması, konservatif kavite preparasyonuna imkan sağlaması ve tamir edilebilmesi avantajlarının yanı sıra polimerizasyon büzülmesi, fonksiyonel tüberküllerde kullanımında aşınma direncinin az olması gibi dezavantajları bulunmaktadır. 1960'ların başından günümüze kadar kompozit rezinler hakkında çeşitli araştırmalar yapılmış, kompozit rezin materyali geliştirilmeye çalışılmıştır. Geliştirilen özellikler ve bu alanda yapılan araştırmalar ile kompozit rezinlerin dezavantajlarının elimine edilmesi hedeflenmiştir. Bununla birlikte literatürde kompozit rezin ile ilgili hem in vivo hem de in vitro araştırmalar ın sayısı da artmıştır . Literatürdeki in vivo araştırmalarda hastaların yaşı, cinsiyeti ve incelenen toplam hasta sayısı gibi hastaya ait veriler yer almakla birlikte kullanılan materyaller, materyallerin klinik değerlendirme kriterlerine ait veriler, restorasyon ömrü gibi veriler de çalışmanın değerlendirilen verileri arasında yer almaktadır. Bu makalede, kompozit rezin restorasyonlar ve diğer restoratif materyaller ile ilgili literatürde yapılan 2010 ve sonrası in vivo ve in vitro çalışmalar derlenmiş ve bu çalışmalarda yer alan tüm veriler incelenerek tablolar halinde sunulmuştur.

“…Modern polymer-based adhesive systems are divided into total etching systems, which consist of two or three components, and self-etching adhesives, which are available in one-or two-stage version [8,9]. Adhesives of all types not only create a unique joint between photocomposite materials and hard tissues of teeth, but also allow to comply with the requirements of minimally invasive preparation of cavities [10].…”

Photocomposite materials and adhesive systems are used for direct tooth restoration, among which 5th generation systems are most often used. To ensure curing, they are exposed to the light flux of the dental photopolymerizer, but the requirements and conditions of such exposure are insufficiently studied. The aim – clinical evaluation of direct photocomposite restorations of teeth performed using an adhesive system, the curing of which was carried out in different light conditions. Materials and methods. 185 people aged from 19 to 44 years were examined, in which 185 lateral teeth with carious cavities of the 1st class according to Black for medium and deep caries were restored by direct method from nanophotocomposite material. In patients of group 1 during the restoration of 62 teeth the polymerization of the adhesive system of the 5th generation was performed with a light flux of constant intensity 1500 mW/cm², in patients of group 2 were restored 60 teeth with polymerization of the same adhesive system with light flux by "soft start" with a final intensity of 1500 mW/cm², 63 teeth in persons of group 3 were restored with a gradual light effect of 1500 mW/cm² on the adhesive system at the bottom and each of the cavity walls using an additional device. The state of recovery was examined after 12 and 24 months. Results. Within 12 months, the largest total number of disorders according to the clinical criteria "marginal adhesion", "marginal staining", "postoperative sensitivity" and "secondary caries" was found in patients of agroups 1 and 2, violations were found in 10 and 13 restorations, respectively (16.1±4.9 % and 21.7±5.8 % of the number of restorations in each group). In persons of group 3, disorders were identified in 3 restored teeth (4.8±2.6 %), which is statistically significant (p<0.05) better. After 24 months, statistically significant (p<0.05) the best indicators were again in patients of group 3, violations were found only in 4 restorations (6.7±3.2 % of them in this period). The worst was the state of recovery in persons of group 2, they had disorders in 20 restorations (42.6±10.4 %), in patients of group 1 – in 16 restorations (30.8±8.0 %). Conclusions. Direct restoration of teeth from nanophotocomposite material, performed using the 5th generation adhesive system under the condition of its gradual polymerization at the bottom and each of the walls of the carious cavity of сlass 1 according to Black, showed high clinical efficiency, which in 12 and 24 months amounted to, respectively, 93.7±3.4 % and 88.9±3.5 %.
