background. repairing aged composite resin is a challenging process. many surface treatment options have been proposed to this end. this study evaluated the effect of different surface treatments on the shear bond strength (sbs) of nanofilled composite resin repairs. methods. seventy-five cylindrical specimens of a filtek z350xt composite resin were fabricated and stored in 37°c distilled water...

objective: ceramics have advantages such as optimal esthetics and biocompatibility. however, in the oral environment, they are subjected to high levels of stress due to masticatory forces, saliva, thermal changes and alterations of ph, which increase their risk of fracture. since replacement of these restorations is costly and time-consuming, composite resin is often used for intraoral repair o...

objectives: repairing composite restorations is a challenging procedure especially when two different types of composites are used. this study aimed to compare the repair strength of silorane-based composite (sc) (filtek p90) with that of preheated sc, methacrylate composite (mc)(z250), flowable mc (filtek supreme plus) and different adhesive/composite combinations. materials and methods : eigh...

objectives: composite repair is a minimally invasive and conservative approach. this study aimed to evaluate the effect of an additional hydrophobic resin layer on the repair shear bond strength of a silorane-based composite repaired with silorane or methacrylate-based composite. materials and methods: sixty bar-shaped composite blocks were fabricated and stored in saline for 72 hours. the surf...

Dental composites and antibacterial restorative materials are also considered;4. Provides a concise overview of non-metallic biomaterials for dental clinicians, mat...

background & aim: repair or replacement of restorations is one of the main necessities for health promotion. however, it has its own physical, psychological and economical side effects. the aim of this study was to investigate the prevalence of factors causing restoration replacement or repair. methods & materials: a non probable sampling was used for this cross – sectional observational descri...

Background: The present study aimed to assess the efficacy of Meperidine for pain relief in children after orthopedic, abdominal surgery, and laceration repair. Materials and Methods: A systematic serch was performed using the following online databa...

Replacement of a restoration leads to excessive cutting of the otherwise healthy tooth structure which affects the integrity of teeth. Repairing existing glass ionomer restorations may appear to be a good alternative to complete replacement of the restoration which presents no evidence of failure on clinical exam. The objectives of the study were to determine the proportion of faculty advocatin...

introdouction: overhang refers to the extension of restoration material from the cavity. it has an important role in decay, plaque accumulation and periodontal disease, so the aim of this study is determining the frequency of restoration overhang in patients in anzali, guilan. materials and methods: this descriptive cross-sectional study was completed using 293 patients who visited for routine ...
