Objective: The aim of the study was to investigate fracture strength different composite resins and quantity voids in conventional posterior composite, high-flow flowable bulk-fill fiber-reinforced composite. Materials Methods: Forty-four caries-free, freshly extracted mandibular premolars were used for this study. Teeth prepared cavity root canal treatment. Subsequently, treatment applied teet...

Early tooth-colored restorative materials were weak and only suitable for anterior teeth. Over time, composites were developed that offered improved properties enabling their use in posterior teeth where subject to occlusal loading and forces of mastication. Secondary caries is the main reason for failure of both amalgam and composite restorations. Amalgam restorations offer ease-of-use but poo...

The aim of this article was to report on the attitudes, opinions and confidences of final year dental students in three European schools towards the restoration of posterior teeth and in particular towards the use of amalgam and resin composite. One hundred and twenty-eight pre-piloted questionnaires were distributed to final year dental students in Cardiff, Dublin and Malmö. The questionnaire ...

  Objective: Secondary caries is a common problem in dental treatments and its occurrence is attributed to several factors. The present study aimed at assessing the prevalence of secondary caries in posterior teeth of patients presenting to the Department of Operative Dentistry, Shahid Beheshti Dental School.   Methods: This descriptive study was conducted on 350 patients with 1,339 posterior t...

OBJECTIVES To assess the knowledge of Jordanian dentists toward phase down of dental amalgam as recommended by the Minamata Convention, and their training and competency in placing posterior composites.  Methods: This study was conducted through structured questionnaire interviews with randomly selected cohort of dentists in Jordan between March 2015 and June 2015. Out of 230 dentists who were ...

Introduction: Posterior reduction probably reduces only the periphery of the endplate with its strong annular attachments while the central area remains depressed allowing for efficient realignment of the spine, direct and indirect decompression. With distraction force, restoration of vertebral body height and partial clearance of bone or discal fragments from within the spinal canal by ligamen...

A 10-question survey was mailed to the 10 Canadian faculties of dentistry to determine current approaches to teaching undergraduates about silver amalgam and resin composite for posterior restorations in adults and children. Responses were received from all 10 pedodontic programs and from 8 of the 10 operative and restorative programs. The use of silver amalgam and posterior composite for resto...

BACKGROUND Limited information is available from randomized clinical trials comparing the longevity of amalgam and resin-based compomer/composite restorations. The authors compared replacement rates of these types of restorations in posterior teeth during the five-year follow-up of the New England Children's Amalgam Trial. METHODS The authors randomized children aged 6 to 10 years who had two...

Recent clinical studies have suggested that composite resin may be an effective restorative material for the restoration of Class I and Class II preparations in primary molars for up to three years. The objective of this study was to advance understanding ot: the clinical performance of composite resin in primary molars. Two composite resin systems (Profile and Visio Fil) and two cavity prepara...
