PENGARUH AGITASI DAN LAMA PENGERINGAN UDARA PADA PENGAPLIKASIAN SELF ETCHING ONE STEP ADHESIVE TERHADAP KEKUATAN GESER PELEKATAN RESIN KOMPOSIT PADA DENTIN

Self etching one step adhesive is easily and fast applied, however this system shows the lowest bond strength. Many researches have been done to optimize this system�s bond strength. The purpose of the study was to investigate the effect of agitation and air drying time in self etching one step adhesive application on composite resin shear bond strength to dentin. Thirty caries free maxillary premolar teeth were prepared and fixed using self cure acrylic resin. All teeth were randomly assigned in six groups. Self etching one step adhesive (G Bond, GC) was applied with and without agitation followed by air-drying time of 0 (without air drying), three and five seconds, and was cured for 20 seconds. Composite resin (Solare, GC), was placed over cured adhesive and was cured for 20 seconds. The research subjects were kept in cotton wool soaked with distilled water and placed in an airtight box for 24 hours. The subjects were thermocycled (4°C and 55°C each of 1 minute), then dried and tested. Data obtained were analyzed using two ways anava and LSD post-hoc test. The statistical analysis using two ways anava revealed that agitation and air drying time affected the bond strength to dentin.(p
