I. Introduction
The research paper titled "The Evaluation of the Relationship between Changes in Masseter Muscle Thickness and Tooth Clenching Habits of Bruxism Patients Treated with Botulinum Toxin A" aims to assess the connection between changes in masseter muscle thickness and tooth clenching habits in bruxism patients who received treatment with botulinum toxin A (BT-A).
II. Methodology
The study included twenty-five patients, diagnosed with possible sleep bruxism. The Fonseca Anamnestic Index was used to evaluate the patients' clenching habits and depression levels before and six months after treatment. Ultrasonography was employed to measure masseter muscle thickness before and three and six months after treatment. All patients received 50 U of BT-A injections, 25 U per masseter.
III. Results
The study found a significant decrease in masseter muscle thickness three and six months after BT-A treatment. There was also a statistically significant decrease in Fonseca scores (evaluating teeth clenching habits) six months after treatment. However, the decrease in depression levels was not statistically significant.
IV. Discussion
The results indicate that BT-A injections are an effective, safe, and side effect-free treatment for bruxism and masseter hypertrophy. The study's findings suggest that BT-A decreases masticatory muscle contraction associated with bruxism, leading to a reduction in masseter muscle thickness. This treatment could potentially minimize bruxism symptoms and related complications.
It is important to note the limitations of this study. The sample size was relatively small, with only 25 patients included. Additionally, the study focused solely on BT-A treatment and did not compare it to other treatment methods. Further research is needed to validate these findings and explore other potential treatments for bruxism.
V. Conclusion
In conclusion, this research highlights the effectiveness of BT-A injections in the treatment of bruxism and masseter hypertrophy. The study demonstrated a significant decrease in masseter muscle thickness and improved clenching habits after BT-A treatment. However, further research with larger sample sizes and comparative studies is necessary to confirm these findings and expand our understanding of bruxism treatment options.
