Understanding the Relationship between Morphological Variation of Sella Turcica and Skeletal Class III Malocclusion at RSGMP FKG USU

Introduction

The study of craniofacial morphology is a crucial aspect of orthodontics, as it helps in understanding the relationship between the structure of the skull and the position of the teeth. Sella Turcica, a small depression in the sphenoid bone, plays a significant role in evaluating craniofacial morphology and jaw relations with the cranium. This study aims to investigate the relationship between the morphological variations of Sella Turcica and Skeletal Class III Malocclusion in patients at RSGMP FKG USU, Medan, Indonesia.

Background

Sella Turcica is an important anatomical structure that is often used in the orthodontic field as a benchmark for measuring cephalometry. This structure plays a role in evaluating craniofacial morphology, jaw relations with cranium, as well as in the superimposition of the cephalometric serial. Class III malocclusion is a condition in which the position of the lower jaw is more advanced compared to the upper jaw, which can cause an imbalance of facial functions and aesthetic. The study of Sella Turcica's morphological variation is essential in understanding the underlying causes of Class III malocclusion.

Methodology

This study involved 104 samples of lateral cephalometric X-ray photos, taken from patients aged between 17 and 35 years. The sample is divided into two groups: The first group consists of 52 lateral cephalograms with class I malocclusion, and the second group consists of 52 lateral cephalograms with class III malocclusion. Sella Turcica's morphological variation was analyzed using the tracing cephalometric method based on Axelsson's theory and her colleagues.

Research Result

The results showed a significant difference in the morphology of Sella Turcica between the two groups. Normal Morphology Sella Turcica is more common in the class I malocclusion group, where 67.3% of the subject has normal morphology. Conversely, only 17.3% of the subject with class III malocclusion showed normal morphology. In addition, the morphological variation of bridging in Sella Turcica is more commonly found in the class III malocclusion group, which is 30.8%, compared to 13.5% in the class I group.

Analysis and Discussion

This discovery shows a significant relationship between the morphological variations of Sella Turcica and the Skeletal Class III malocclusion. The abnormal Sella Turcica structure, such as bridging, may contribute to the development of this malocclusion. This can be caused by genetic factors, unbalanced bone growth, or interactions between the environment and other biological factors. The study of Sella Turcica's morphological variation is essential in understanding the underlying causes of Class III malocclusion and in developing effective treatment options.

Clinical Implication

This study provides new insights in the diagnosis and treatment of orthodontics, especially for dentists and orthodontists in planning the right intervention for patients with class III malocclusion. By knowing the morphological variation of Sella Turcica, practitioners can consider more effective treatment options for overcoming more complex problems in patients. This study also highlights the importance of cephalometric analysis in understanding the relationship between Sella Turcica's morphological variation and Class III malocclusion.

Conclusion

Overall, this study confirms the morphological differences of Sella Turcica between patients with Skeletal Class III malocclusion and Skeletal Class I. The relationship found between the morphological variations of Sella Turcica and Class III malocclusion provides a foundation for further research and improving strategies in the diagnosis and care of patients in the orthodontic field. Efforts to understand more deeply about the interaction between the morphology of Sella Turcica and the condition of malocclusion will be the key in creating a more comprehensive approach in the practice of orthodontics in the future.

Recommendation

Based on the findings of this study, it is recommended that dentists and orthodontists consider cephalometric analysis as an essential tool in understanding the relationship between Sella Turcica's morphological variation and Class III malocclusion. This study also highlights the importance of further research in understanding the underlying causes of Class III malocclusion and in developing effective treatment options.

Limitation

This study has several limitations, including the small sample size and the use of lateral cephalometric X-ray photos. Future studies should aim to recruit a larger sample size and use more advanced imaging techniques, such as cone beam computed tomography (CBCT), to provide a more comprehensive understanding of the relationship between Sella Turcica's morphological variation and Class III malocclusion.

Future Direction

Future studies should aim to investigate the relationship between Sella Turcica's morphological variation and other types of malocclusion, such as Class II malocclusion. This study also highlights the importance of further research in understanding the underlying causes of Class III malocclusion and in developing effective treatment options.
