introduction: coronal microleakage may significantly reduce the prognosis of endodontic treatment. temporary restorative materials have a crucial role in preventing the infection of root canals between and after endodontic treatment. this in vitro study was designed to evaluate the coronal microleakage of three temporary restorative materials used in endodontics: coltosol, cavisol and cina. mat...

o bjectives: caries and dental trauma are common reasons for primary anterior teeth restorations in children. this non-control clinical trial was designed to eva- luate crown restorations reinforced with a sectioned file post for the restoration of severely damaged primary maxillary incisors. materials and methods: thirty-eight primary maxillary incisors of 12 children (3-5 years old) with earl...

introduction: the purpose of this in vitro study was to evaluate the sealing ability of the readymade temporary filling and hand mixed materials by assessing coronal microleakage. materials & methods: standardized access cavities were prepared in 80 intact human permanent premolar teeth. they were divided randomly into four experimental groups (n=20). the teeth were restored using one of the te...

a virtual absence of palliative, preventive and restorative care characterizes juvenile oral health care in most of the developing and underdeveloped countries. consequently, carious cavities remain untreated, which leads to pain, discomfort and functional limitation. it further, impacts negatively upon general health and cognitive development apart from causing decreased masticatory efficiency...

Amalgam was banned as a dental restorative material in Norway in 2008 due to environmental considerations. An electronic questionnaire was sent to all dentists in the member register of the Norwegian Dental Association (NTF) one year later, to evaluate dentists' satisfaction with alternative restorative materials and to explore dentists' treatment choices of fractured amalgam restorations. Repl...

objective: preservation of unsupported occlusal enamel after removal of underlying carious dentin may result in maintenance of aesthetics as well as wear resistance against the opposing enamel. this study investigates the influence of different restorative materials and bonding agents on reinforcement of unsupported enamel in molars and compares it with sound dentin. materials and methods: in t...

objectives: fracture strength is an important factor influencing the clinical long-term success of implant-supported prostheses especially in high stress situations like excessive crown height space (chs). the purpose of this study was to compare the fracture strength of implant-supported fixed partial dentures (fpds) with excessive crown height, fabricated from three different materials. mater...

objective: the purpose of the present study was to assess the microleakage of composite restorations with and without a cervical amalgam base and to compare the results of dif-ferent composites and bonding agents. materials and methods: one hundred and twenty mesio-occlusal (mo) and disto-occlusal (do) class ii cavities were prepared on sixty extracted permanent premolar teeth. the teeth were r...

conclusions estelite sigma quick composite had wear resistance similar to that of nano- and microfilled composites. estelite flowable composites demonstrated similar wear resistance to that of a posterior composite. results the wear amounts of the composites are as follows in order: estelite sigma quick (1886.9 ± 518.5 μm2), estelite flow quick (2708.9 ± 578.1 μm2), estelite high flow (3206 ± 2...

The aim of this study was to carry out a representative survey on the implementation of and experience with repairs of single-tooth restorations among dentists in the Canton of Zurich, Switzerland. An anonymous questionnaire was sent to all 1,411 dentists registered in the Canton of Zurich; 38.9% of the delivered questionnaires were returned and 35.3% could be evaluated. The statistical analysi...
