Effect of Curing Modes of Dual-curing Core Systems on Microtensile Bond Strength to Dentin and Formation of an Acid-Base Resistant Zone.

J Adhes Dent. 2011 May 4; Li N, Takagaki T, Sadr A, Waidyasekera K, Ikeda M, Chen J, Nikaido T, Tagami J Purpose: To evaluate the microtensile bond strength (μTBS) and acid-base resistant zone (ABRZ) of two dualcuring core systems to dentin using four curing modes. Materials and Methods: Sixty-four caries-free human molars were randomly … Continue reading »

Roughness and pH changes of enamel surface induced by soft drinks in vitro-applications of stylus profilometry, focus variation 3D scanning microscopy and micro pH sensor.

Dent Mater J. 2011 Jun 2; 30(3): 404-10Fujii M, Kitasako Y, Sadr A, Tagami J This study aimed to evaluate enamel surface roughness (Ra) and pH before and after erosion by soft drinks. Enamel was exposed to a soft drink (cola, orange juice or green tea) for 1, 5 or 60 min; Ra was measured … Continue reading »

Non-invasive quantification of resin-dentin interfacial gaps using optical coherence tomography: Validation against confocal microscopy.

Dent Mater. 2011 Jun 12; Bakhsh TA, Sadr A, Shimada Y, Tagami J, Sumi Y OBJECTIVES: Regardless of the cause, gap formation at the tooth-restoration interface may result in treatment failure; non-destructive assessment and monitoring of these defects are important. The aim of this in vitro study is to assess the tooth-restoration interface using a … Continue reading »
