background and aims. the purpose of this investigation was to assess the placement and replacement of resin-based composite restorations and related factors in a private practice in greece. materials and methods. the study included 1500 subjects, 720 males and 780 females, aged 18 to 52 years old. the clinical examination involved calculation of the number of teeth with primary caries and faile...

introduction: one of the clinical problems in orthodontics is the bonding of brackets tocomposite restorations. the aim of this study was to evaluate the shear bondstrength of brackets bonded to composite restorations using excite. methods:forty brackets were bonded to composite surfaces, which were embedded inacrylic resin. one of the following four protocols was employed for surfacepreparatio...

Using the information from remake request slips in a dental school's predoctoral clinic, we examined the short-term survival of Class II resin composite restorations versus Class II dental amalgam restorations. In the student clinic, resin composite is used in approximately 58 percent of Class II restorations placed, and dental amalgam is used in the remaining 42 percent. In the period examined...

The current standard preparation for Class IV composite restorations is the placement of a bevel on all enamel margins. This study evaluated chamfered and beveled preparations for Class IV restorations of lesions with microfilled and macrofilled composite resin. Forty incisors were obtained and standardized lesions for Class IV restorations were formed. Twenty teeth had a 1.5-mm bevel placed an...

Objectives: To determine the marginal microleakage of Class II restorations made with different composite base materials and the static load-bearing capacity of direct composite onlay restorations. Methods: Class II cavities were prepared in 40 extracted molars. They were divided into five groups (n = 8/group) depending on composite base material used (everX Posterior, SDR, Tetric EvoFlow). Aft...

Composite resins for posterior tooth restorations have become a viable alternative to dental amalgam. Failures sometimes cannot be easily explained, and we hypothesize that a genetic component may influence longevity of restorations. We aimed to determine if there is any evidence for a difference in the performance of amalgams versus composite resin in extensive posterior restorations. We also ...

OBJECTIVE Despite the incremental build-up of resin composite restorations, their polymerization shrinkage during curing presents a serious problem. Indirect composite resin systems represent an alternative in overcoming some of the deficiencies of direct composite restorations. The hypothesis of the present study states that the clinical performance of restorations may be affected by different...

introduction: the restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. the aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. methods: e...

Dental clinicians have an expanding range of biomaterial choices for restoring tooth structure. Scientific developments in cariology, advances in dental biomaterials, and patients' esthetic concerns have led to a reduction in amalgam restorations and an increase in composite restorations. The aim of this study was to compare teaching time with students' clinical procedures in amalgam and compos...
