Background: Bleaching is a procedure that involves lightening the color of a tooth through the application of a chemical agent, which has a side effect in the form of changes to the surface of the composite resin material. Meanwhile, surface roughness plays a vital role in determining a material’s interaction with the oral environment due to the poor surface texture of dental materials. It has a significant influence on plaque accumulation and causes other diseases. However, studies on the effect of bleaching agents on the surface roughness of dental materials have reported controversial results. Objectives: This study aimed to analyze the effect of in-home bleaching agents on the surface roughness of nanofilled and microhybrid composite resin. Methods: Nanofilled composite resin FiltekTM Z350 XT Universal Restorative (3M ESPE) and microhybrid composite resin FiltekTM Z250 Universal Restorative (3M ESPE) were used in the present study. Sixteen specimens were prepared from each type of composite resin that represented by group A for nanofilled composite resin and group B for microhybrid composite resin (total number of specimens were 32). Each specimen was prepared by compressing a sufficient amount of material into a mold of 6 mm in diameter and 2 mm in thickness using glass slides with celluloid strip, then given a load of 500 grams. In-home bleaching agents (Opalescence Tooth Whitening Systems 10% Carbamide Peroxide Concentrations) were applied 8-10 hours/day. All treatment was conducted at 37°C temperature, and an in-home bleaching agent was applied and rinsed off daily for one week and stored in distilled water during the hiatus period. Then, the surface roughness of all specimens was measured and recorded (Ra) value in μm using a surface roughness tester (Surtronic® S-128) before and after being treated. Data were statistically analyzed with Paired T-Test and Independent T-Test. Result: There was a statistically significant difference between the surface roughness of nanofilled and microhybrid composite resin before and after being bleached with an in-home bleaching agent (p<0,005). There was a statistically significant difference between nanofilled and microhybrid composite resin after being bleached with an in-home bleaching agent (p<0,005). Conclusion: In-home bleaching agent significantly increased the surface roughness value of both types of composite resin with nanofilled composite resin is lower than microhybrid composite resin. Surface roughness for both composite resins is still clinically acceptable because values tested below the critical threshold of 0,2 μm."
