Introduction

In the world of dentistry, the importance of denture disinfection cannot be ignored. The disinfection method can be done in a mechanical, chemical, or combination of both. For denture users who have limitations of motor function, mechanical methods become difficult to apply and are less effective. Therefore, chemical disinfection methods such as soaking dentures in disinfection solutions are more recommended alternatives. Chlorhexidine, as one of the non-traditional disinfection ingredients, and castor oil (Ricinus Communis Oil), which is a traditional disinfection, is currently receiving attention in research in the field of dentistry. However, the use of these two ingredients as denture disinfection also has the potential to affect the mechanical properties of heat polymerization acrylic resins, including surface hardness.

Background

Denture disinfection is a crucial step in maintaining the health and hygiene of denture users. The use of chlorhexidine and castor oil as denture disinfection agents has gained attention in recent years due to their potential benefits. However, the effects of these agents on the mechanical properties of heat polymerization acrylic resins are not well understood. This study aims to explore the effect of disinfection with chlorhexidine and castor oil on the hard surface of the denture base of the acrylic resin that is commonly used.

Methodology

This research design is experimental laboratory with a sample in the form of a cylindrical acrylic resin in the form of a cylindrical, diameter of 30 mm and a thickness of 5 mm. The study was conducted with six different treatments, namely groups disinfected using 0.2% chlorhexidine for 15, 20, and 25 days, as well as groups that use 10% castor oil over the same period. Each group consists of five samples, so the total sample used in this study is 30.

Results

The analysis results show that in groups A1 and B1, there is no significant effect (p = 0.280). The same thing happened in groups A2 and B2 (p = 0.365). However, the results showed a significant influence on groups of A3 and B3 (p = 0.003), which showed that disinfection in a longer period had an impact on the hardness of the surface of the denture base.

Discussion

The results of this study suggest that the use of chlorhexidine and castor oil as denture disinfection agents can have a significant impact on the mechanical properties of heat polymerization acrylic resins. The study found that disinfection in a longer period had a significant effect on the hardness of the surface of the denture base. This suggests that the selection of proper disinfection methods and sufficient duration can have important implications for the durability and quality of dentures in the long run.

Conclusion

The conclusion that can be drawn from this study is that there is no influence on chlorhexidine disinfection of 0.2% and 10% castor oil on the surface of the base of the heating acrylic denture base in the simulation period of 3 and 4 years. However, in a 5-year simulation, there is a significant effect of the two disinfection materials. This shows that the selection of proper disinfection methods and sufficient duration can have important implications for the durability and quality of dentures in the long run. Further research is still needed to understand the mechanisms that occur and find the best solutions in safe and effective denture disinfection.

Recommendations

Based on the results of this study, the following recommendations can be made:

The use of chlorhexidine and castor oil as denture disinfection agents should be further investigated to understand their effects on the mechanical properties of heat polymerization acrylic resins.
The selection of proper disinfection methods and sufficient duration should be taken into account to ensure the durability and quality of dentures in the long run.
Further research is needed to understand the mechanisms that occur and find the best solutions in safe and effective denture disinfection.

Limitations

This study has several limitations that should be taken into account when interpreting the results. These include:

The study was conducted in a laboratory setting, which may not reflect the real-world conditions of denture use.
The sample size was relatively small, which may not be representative of the larger population of denture users.
The study only investigated the effects of chlorhexidine and castor oil on the mechanical properties of heat polymerization acrylic resins, and did not investigate other potential effects.

Future Directions

Based on the results of this study, several future directions can be suggested:

Further research is needed to understand the mechanisms that occur when chlorhexidine and castor oil are used as denture disinfection agents.
The effects of other disinfection agents on the mechanical properties of heat polymerization acrylic resins should be investigated.
The development of new denture disinfection methods that are safe and effective should be explored.
