The Effect of Immersion of Post-Hemimaksylectomy Patient Alginate Mold with 0.5% Hypochlorite Sodium on the Number of Klebsiella Pneumoniae and Changes in Model Dimensions

Introduction

Pneumonia, a life-threatening disease, is often caused by bacteria Klebsiella pneumoniae. In Indonesia, hemimaksylectomy, which involves the removal of some of the upper jawbones, has a high prevalence. After undergoing hemimaksylectomy, the relationship between the nasal cavity, antrum, and nasopharynx becomes open, allowing pathogenic bacteria such as Klebsiella pneumoniae to easily enter the oral cavity. Post-hemimaksylectomy patients require obturator making, a prosthetic device that covers the lost cavity, which involves cooperation between oral and prostodontic surgeons. However, alginate molds used in the process of making obturators have the potential to be contaminated by bacteria, including Klebsiella pneumoniae. Therefore, an effective disinfection method is needed to ensure the cleanliness and safety of printed obturators.

The Importance of Disinfection in Obturator Making

Obturators are prosthetic devices that cover the lost cavity after hemimaksylectomy. The process of making obturators begins with taking alginate molds, which are obtained from post-hemimaksylectomy patients and master models. However, alginate molds have the potential to be contaminated by bacteria, including Klebsiella pneumoniae. This can lead to infection and compromise the safety of patients. Therefore, an effective disinfection method is needed to ensure the cleanliness and safety of printed obturators.

The Effect of Immersion of Alginate Mold with 0.5% Hypochlorite Sodium Solution

This study aims to determine the effect of immersion of post-hemimaksylectomy patient alginate molds with 0.5% hypochlorite sodium solution on the number of Klebsiella pneumoniae and changes in model dimensions. The study uses an experimental method with 32 samples divided into 8 groups:

*** Control group: ** Two control groups, each soaked in water for 2 minutes and 4 minutes. *** Disinfection Group: ** Two groups of disinfection, each soaked in a 0.5% hypochlorite sodium solution for 2 minutes and 4 minutes.

Alginate molds are obtained from post-hemimaksylectomy patients and master models. After immersion, a swab is performed on the mold surface and model to identify Klebsiella pneumoniae, which is then cultured on the agar macconkey media. The number of bacterial colonies is calculated to determine the number of Klebsiella pneumoniae. Dimensional changes are measured using digital caliper.

Research Results

The results showed that the immersion of alginate mold with a 0.5% hypochlorite sodium solution for 2 and 4 minutes affected the number of Klebsiella pneumoniae and changes in model dimensions. Soaking for 4 minutes proved effective in killing Klebsiella pneumoniae both in molds and models. In addition, changes in dimensions that occur are still in accordance with existing specifications (American dental association), which indicates that immersion for 4 minutes does not cause significant dimensional changes.

Conclusion and Recommendations

This study concluded that the immersion of the post-hemimaksylectomy patient alginate mold with 0.5% hypochlorite sodium for 4 minutes is an effective method in disinfecting alginate molds. This method is able to kill Klebsiella pneumoniae without causing significant dimensional changes. The recommendation of this study is to apply this disinfection method in the process of making obturators after hemimaksylectomy. This aims to reduce the risk of infection and increase safety for patients.

Future Research Directions

In addition to the findings of this study, further research is needed to examine the effect of immersion with a 0.5% hypochlorite sodium on mechanical properties and the strength of the alginate mold. This research can also be repeated with a more varied immersion period. This research is expected to provide useful information for professionals in the health sector, especially oral and prostodontic surgeons, in applying the practice of disinfecting alginate molds that are safe and effective.

Implications for Clinical Practice

The findings of this study have implications for clinical practice in the field of oral and prostodontic surgery. The use of 0.5% hypochlorite sodium solution for disinfecting alginate molds is a simple and effective method that can be applied in clinical practice. This method can help reduce the risk of infection and increase safety for patients. Therefore, it is recommended that oral and prostodontic surgeons apply this disinfection method in their practice.

Limitations of the Study

This study has some limitations. The study only examined the effect of immersion with a 0.5% hypochlorite sodium solution on the number of Klebsiella pneumoniae and changes in model dimensions. Further research is needed to examine the effect of immersion on mechanical properties and the strength of the alginate mold. In addition, the study only used a limited number of samples, and further research is needed to confirm the findings of this study.

Conclusion

In conclusion, this study found that the immersion of post-hemimaksylectomy patient alginate mold with 0.5% hypochlorite sodium solution for 4 minutes is an effective method in disinfecting alginate molds. This method is able to kill Klebsiella pneumoniae without causing significant dimensional changes. The recommendation of this study is to apply this disinfection method in the process of making obturators after hemimaksylectomy. This aims to reduce the risk of infection and increase safety for patients.
