OBJECTIVES The objective was to evaluate the response of human pulps capped with different components from a total-etch three-step adhesive system. METHODS Direct pulp capping was performed in 25 caries-free human premolars scheduled for extraction due to orthodontic treatment. The teeth were randomly divided in five groups, and capped with the following materials: Group 1-acid+primer+adhesiv...

OBJECTIVES The purpose of this study was to evaluate the cytotoxic effect of six dental adhesives (Admira Bond, Clearfil Liner Bond 2V, ED Primer II, Fuji Bond LC, Gluma Comfort Bond, and NanoBond) applied to cell cultures. METHODS The experiments were performed on two cell lines, rat pulp cells (RPC-C2A) and human lung fibroblasts (MRC5). Samples of the adhesives were light-cured and placed ...

BACKGROUND This paper aimed to study the effect of two enamel protective agents on the shear bond strength (SBS) of orthodontic brackets bonded with conventional and self-etching primer (SEP) adhesive systems. METHODS The two protective agents used were resin infiltrate (ICON) and Clinpro; the two adhesive systems used were self-etching primer system (Transbond Plus Self Etching Primer + Tran...

objective: in this study, the effect of bur cutting efficacy was evaluated on microleakage of class v composite restorations with two adhesive systems. materials and methods: class v cavities were produced on sound extracted human teeth, which had been assigned randomly to one of six groups (n=15) as follows: groups 1 and 6 were prepared using used rough diamond bur; group 2 and 5 were prepared...

OBJECTIVE Although self-etching bonding systems (SES) are indicated to prepare dental enamel for bonding, concerns have been expressed regarding their effectiveness. The aim of this study was to analyze the etching pattern (EP) of nine SES in comparison with 35% and 34% phosphoric acid etchants (FA) on intact (IN) and ground (GR) enamel surface. MATERIALS AND METHODS Twenty-two human third mo...

Introdouction: According to the importance of enamel discoloration and controversy regarding the effect of different orthodontic bonding materials on tooth discoloration, the aim of this study was to determine enamel discoloration following orthodontic brackets using different bonding materials. Materials and methods: This in-vitro study, 30 recently extracted human premolars with inta...
