Objective: Selection of an appropriate shade of composite is critical in achieving an esthetic restoration. Different systems are used to assess and describe color parameters. This study aimed to assess the effect of color and thickness of Filtek Supreme (FS) and Premise (P) composite resins on correction of tooth discoloration.   Methods: In this in vitro experimental study, 10 anterior teet...

The radiopacity of esthetic restorative materials has been established as an important requirement, improving the radiographic diagnosis. The aim of this study was to evaluate the radiopacity of six restorative materials using a direct digital image system, comparing them to the dental tissues (enamel-dentin), expressed as equivalent thickness of aluminum (millimeters of aluminum). Five specime...

Background: After indirect capping, injured odontoblasts generate reactionary dentin, whereas after direct capping of a pulp exposure pulp, cells stimulate the formation of reparative dentin. The aim of this study was to evaluate and compare the effects of two direct capping agents on pulp tissue reactions: Hydrogel (a bovine serum albumin (BSA)/glutaraldehyde,) and Dycal (a calcium hydroxide-b...

This study evaluates the influence of root dentin treatment with NaOCl alone and combined with EDTA, with and without ultrasound activation, on the push-out bond strength (BS) of fiber-reinforced posts in weakened roots, cemented with RelyX or Panavia. The root canals of 42 maxillary canines were instrumented with Reciproc and 2.5% NaOCl. In the coronal 12mm of all canals, experimental weakenin...

OBJECTIVE: This study is to compare the dentin bridge thickness achieved using calcium hydroxide and MTA radiographs. METHODOLOGY: Single blinded randomized controlled trial conducted in Operative Dentistry department at Fatima Jinnah Dental College Hospital, Karachi. A total of 100 premolar molar teeth with class I II cavities were included this study. The participants assigned into two groups...

AIM To evaluate and compare the antibacterial efficacy of turmeric extract as an intracanal medicament against E. faecalis and its effect on the microhardness of root dentin in comparison with calcium hydroxide and 2% chlorhexidine gel. MATERIALS AND METHODS One hundred and fourty dentin blocks were prepared from 70 extracted human single-rooted teeth and standardized. For antibacterial asses...

background and aims. various factors influence the interfacial bond between the fiber posts and root canal dentin. the aim of the present study was to evaluate the effect of pre-warming of resin cement on the push-out bond strength of fiber posts to various segments of root canal dentin. materials and methods. in this in vitro study, 40 single-rooted human premolars were decoronated and underwe...

background: managing dental caries in young children is demanding due to the elusions present on the right diagnostic criteria for treatment. the present study evaluated the histological status of pulp tissues extracted from primary second molar with caries involvement. histological findings are correlated with clinical and radiographic assessment. materials and methods: simple experimental stu...
