Article Synopsis
- The study examines how different polymerization methods affect the properties of composite resins used in dentistry, particularly their microhardness and strength.
- A total of 150 resin specimens were tested using three polymerization methods: light curing, photopolymerization with autoclave, and photopolymerization with microwave, across five different resin types.
- Results showed that light curing produced the highest microhardness values, while Brilliant Everglow resin consistently showed the lowest values, regardless of the polymerization method used.
Background: Since only a few data have been published concerning the effects of resinous dental materials on the pulp-dentin complex, the aim of this study was to evaluate the biocompatibility of resin-based materials applied as liners in deep cavities prepared in human teeth.
Methods: After preparing class V cavities, the following dental materials were applied on the axial walls: group 1, Vitrebond (VIT; 3M ESPE); group 2, Ultra-Blend Plus (UBP; Untradent); and group 3, Clearfil SE Bond (CSEB; Kuraray). In group 4 (control), the hard-setting calcium hydroxide cement Dycal (CH; Caulk/Dentsply) was used.
Short-term evaluation of the pulpo-dentin complex response to a resin-modified glass-ionomer cement and a bonding agent applied in deep cavities.

Objectives: To evaluate the response of the pulpo-dentin complex following application of a resin-modified glass-ionomer cement or an adhesive system in deep cavities performed in human teeth.
Methods: Deep class V cavities were prepared on the buccal surface of 26 premolars. In Group 1 the cavity walls (dentin) and enamel were conditioned with 32% phosphoric acid and the dentin adhesive system One Step (Bisco, Inc.
Objectives: The aim of this in vivo study was to evaluate the human dental pulp response when a one-bottle adhesive system was applied on etched or unetched deep dentine.
Methods: Eighteen class V deep cavity preparations were divided in three groups: group 1-total etching + two coats of single bond (SB) + composite resin (Z-100); group 2-enamel etching + two coats of SB + Z-100; group 3-cavity floor lined with a calcium hydroxide liner (Dycal) + acid-etching of enamel and lateral walls + two coats of SB + Z-100. Two teeth were used as intact control group.
