The Impact of Whitening Toothpaste on the Roughness and Surface Hardness of the Crown while the Composite Resin

Introduction

The temporary crown, which is temporarily installed on the gear that has been prepared, is often made of composite resin. Composite resins have many advantages, such as strength and aesthetics, but also have a weakness that is sensitivity to abrasion. The use of whitening toothpaste, which contains abrasive material, can increase roughness and reduce the surface hardness of composite resins, which in turn have an impact on the service and aesthetics of the crown temporarily. This research investigates the effect of whitening toothpaste on the roughness and surface hardness of the crown while the composite resin.

Background

Composite resins are widely used in dentistry due to their excellent mechanical properties, such as strength and durability. However, they are also prone to sensitivity to abrasion, which can lead to changes in their surface roughness and hardness. The use of whitening toothpaste, which contains abrasive materials such as silica and calcium carbonate, can further exacerbate this problem. The use of whitening toothpaste can increase roughness and reduce the surface hardness of composite resins, which in turn have an impact on the service and aesthetics of the crown temporarily.

Methodology

This study uses the Pre-Post Test Group Design design with 32 crown samples while the composite resin. The sample was divided into two groups, 16 samples for the Roughness Test and 16 for the Violence Test. Each sample is brushed with a special toothbrush machine, then measured roughness and violence. The sample was divided into two groups, 16 samples for the Roughness Test and 16 for the Violence Test.

Results

The results showed that surface roughness increased significantly after being brushed with whitening toothpaste (0.24 μm ± 0.04 before brushing, to 0.30 μm ± 0.06 after being brushed). Likewise, surface hardness also experienced a significant decline (32.29 VHN ± 3.30 before brushed, to 26.52 VHN ± 1.79 after being brushed). The results showed that surface roughness increased significantly after being brushed with whitening toothpaste.

Discussion

Increased roughness and decreased violence have important implications for oral health and aesthetics. Rough surfaces can increase plaque retention, bacteria, and food scraps, thereby increasing the risk of gingival irritation, secondary caries, and wear in adjacent teeth. In addition, changes in shape and color in the crown temporarily can reduce aesthetic values and affect temporary crown life. This can interfere with the success of permanent tooth restoration. Increased roughness and decreased violence have important implications for oral health and aesthetics.

Conclusion

This research provides strong evidence that the use of whitening toothpaste can affect the surface of the crown while the composite resin. It is important for dentists to provide education to patients about the impact of the use of whitening toothpaste on a temporary crown and encourage the use of softer toothpaste in the period the use of temporary crown. Further research is needed to examine the long -term impact of the use of whitening toothpaste on the crown while the composite resin and to find solutions that can minimize the abrasive effect. This research provides strong evidence that the use of whitening toothpaste can affect the surface of the crown while the composite resin.

Recommendations

Based on the findings of this study, the following recommendations are made:

Dentists should educate patients about the impact of whitening toothpaste on temporary crowns.
Patients should be encouraged to use softer toothpaste during the period of temporary crown use.
Further research is needed to examine the long-term impact of whitening toothpaste on the crown while the composite resin.
Solutions should be developed to minimize the abrasive effect of whitening toothpaste on composite resins.

Limitations

This study has several limitations, including:

The sample size was relatively small.
The study only examined the short-term effects of whitening toothpaste on the crown while the composite resin.
The study did not examine the long-term effects of whitening toothpaste on the crown while the composite resin.

Future Research Directions

Future research should focus on examining the long-term effects of whitening toothpaste on the crown while the composite resin. Additionally, research should be conducted to develop solutions that can minimize the abrasive effect of whitening toothpaste on composite resins. Future research should focus on examining the long-term effects of whitening toothpaste on the crown while the composite resin.

Conclusion

In conclusion, this study provides strong evidence that the use of whitening toothpaste can affect the surface of the crown while the composite resin. The findings of this study have important implications for oral health and aesthetics, and highlight the need for further research to examine the long-term effects of whitening toothpaste on the crown while the composite resin. In conclusion, this study provides strong evidence that the use of whitening toothpaste can affect the surface of the crown while the composite resin.
