The Relationship Between the Width of the Nose and Lower Face Height in the Chinese Race in Medan: A Descriptive Study

Introduction

Accurate diagnosis is the foundation of orthodontic treatment. Orthodontic experts rely on measurement parameters on the faces of patients to determine the right diagnosis and plan effective care. One important aspect that needs to be considered is facial harmonization, which includes dental relations, mastication functions, and overall face proportions. Facial harmonization is crucial in achieving optimal and aesthetic results in orthodontic treatment.

In this study, we focus on the relationship between the width of the nose and lower face height in the Chinese race in the city of Medan. The width of the nose base, which is measured as the distance between the two nasal lobes, is expected to give an indication of the lower face height, which is measured as the distance from subnasal to gnathion. Understanding this relationship is essential in determining the ideal lower face height that matches the width of the nose of each individual.

Methodology

This descriptive research involved 168 Chinese racial samples aged 17-25 years in the city of Medan. Data was collected using the multi-stage sampling method (cluster sampling and purposive sampling). The multi-stage sampling method is a technique used to select a representative sample from a larger population. Cluster sampling involves selecting a group of individuals or clusters from the population, while purposive sampling involves selecting individuals based on specific criteria.

The data was analyzed using a computer program to measure the lower face height and width of the nose base. The results were then compared to determine the relationship between the width of the nose and lower face height.

Results

The results showed a significant relationship between the width of the nose and lower face height in the Chinese race in the city of Medan. The average width of the nose in the study group showed a value of P-value 0.000 (p < 0.05), while the average lower face height showed a value of P-value 0.002 (p < 0.05). The Spearman correlation test strengthened this finding by showing a significant relationship (p < 0.05) and a positive correlation coefficient with moderate strength (R = 0.430).

This finding shows that the greater the width of the nose, the greater the lower face in the Chinese race in the city of Medan. This can be an important parameter for orthodontic experts in determining the ideal lower face height that matches the width of the nose of each individual.

Discussion

This study made an important contribution in understanding the proportion of the face and facial harmonization to the Chinese race in the city of Medan. This finding can be used as a reference in orthodontic treatment to achieve optimal and aesthetic results.

However, it is essential to remember that this research is limited to the Chinese race in the city of Medan. Further research with a wider and diverse population is needed to ensure generalizability of these findings. The results of this study can be used as a starting point for further research, and it is essential to consider the limitations of this study when interpreting the results.

Conclusion

In conclusion, this study found a significant relationship between the width of the nose and lower face height in the Chinese race in the city of Medan. The results of this study can be used as a reference in orthodontic treatment to achieve optimal and aesthetic results. However, further research is needed to ensure generalizability of these findings.

Limitations

This study has several limitations. Firstly, the sample size was limited to 168 Chinese racial samples aged 17-25 years in the city of Medan. Secondly, the study only focused on the Chinese race in the city of Medan, and further research is needed to ensure generalizability of these findings. Finally, the study only measured the width of the nose and lower face height, and further research is needed to explore other facial parameters.

Future Directions

Future research should aim to explore the relationship between the width of the nose and lower face height in a wider and diverse population. This can be achieved by conducting a larger-scale study with a more diverse sample population. Additionally, further research should aim to explore other facial parameters, such as the length of the face, the width of the face, and the shape of the face.
