AIM This in vitro study aimed to compare the time required for removal, the presence of residues of restorative material, tooth structure loss and dental surface morphology after removal of composite resin and amalgam restorations from occlusal cavities in primary molars using conventional high-speed bur and CVDentus® ultrasonic diamond tips. MATERIALS AND METHODS A total of 37 primary molars...

Placement of restorations for patients who are physically or intellectually disabled or mentally ill can pose considerable difficulties for the general practitioner. Access to the oral environment is often limited and patient tolerance and concentration may be reduced to rather brief periods of time. Oral hygiene routines may be less than ideal leading to a high caries rate. Enamel surfaces whi...

AIMS The aim of the present study is to compare and assess the fracture resistance of root canal treated teeth with different restorative materials. MATERIALS AND METHODS The present in vitro study was carried out on seventy-five freshly extracted, noncarious, single-canal human lower-first premolars with similar anatomic characteristics. Teeth were randomly assigned to five groups with 15 te...

The purpose of this study was to compare the properties of 2 new dual-cure, bulk-fill restorative composite resins to those of a hybrid composite resin material. Depth of cure, fracture toughness, porosity, microleakage, and volumetric shrinkage properties were examined. With the exception of fracture toughness, significant differences were found among materials. Compared to the incrementally p...

Gold foil is the most underused restorative material in dentistry, and contrary to popular belief, it is still being used in many dental practices. As demonstrated, it can be used more easily than years ago and give the patient a restoration that may last a lifetime. Reasons for not using it have been addressed, and a simplified method of restoration has been explained in detail. It is the hope...

background: obtaining optimal marginal adaption with prefabricated stainless steel crowns (sscs) is diffi cult, especially after removing dental caries or defects in cervical areas. this situation requires the use of an ssc after tooth reconstruction. this study evaluated microleakage and material loss with fi ve restorative materials at ssc margins. materials and methods: one hundred and twent...

The primary objective of the Atraumatic Restorative Treatment (ART) is to reduce the indication of tooth extraction by means of a low-cost technique. Considering the difficulties of Brazilian public services to meet the demand of care of the low-income population, with lack of care to the adult population, which usually receives only emergency care, the aim of this study is to assess the perfor...

The ability to predictably bond thin pieces of tooth-colored restorative material to teeth and expect excellent long-term esthetic and functional results has created a new arena in the practice of dentistry — that of elective cosmetic treatment. This is not to say that these procedures “appeared overnight”; they did not. However, over the last 20 or so years, the materials and technologies have...

Placement of a restorative material in dentin produces the possibility of pulpal injury. In vitro studies have shown that the constituents of dental biomaterials have toxic potentials. In the clinical setting, there may be an immediate reaction of the pulp to, for example, acid etching and to the placement of a bonding agent; however, in most cases the remaining dentin serves as protection agai...

The continuous development of esthetically acceptable adhesive restorative material has made a variety of tooth-colored materials available for clinical use. The advent of visible light polymerizing resin and the use of finer filler particles permit resin composites to be polished to higher degree. The effect of polishing systems on surface finish has been reported to be material-dependent, and...
