RESUMEN
Background: Orthodontic treatment is commonly used to correct misaligned teeth and improve dental aesthetics and function. Archwires play a crucial role in this treatment by exerting forces on teeth, prompting them to shift into desired positions. Materials and Methods: For this experimental study, 60 participants requiring orthodontic treatment were selected and divided into three groups: Group A, treated with stainless steel archwires; Group B, treated with nickel-titanium archwires; and Group C, treated with beta-titanium archwires. Standardized orthodontic procedures were followed for all participants. The rate of tooth movement was measured over a period of 6 months using digital models and a calibrated measurement technique. Results: The study revealed notable differences in the rate of orthodontic tooth movement among the three groups. Group B (nickel-titanium archwires) demonstrated the highest mean rate of tooth movement, with an average of 1.5 mm per month. Group A (stainless steel archwires) exhibited a mean rate of 1.2 mm per month, while Group C (beta-titanium archwires) showed the lowest mean rate at 0.9 mm per month. Conclusion: In conclusion, this study highlights the varying efficacy of different archwire materials in accelerating orthodontic tooth movement. Nickel-titanium archwires exhibited the highest rate of tooth movement compared to stainless steel and beta-titanium archwires.
RESUMEN
This study investigates the effectiveness of nanoparticles in preventing the formation of biofilms on orthodontic brackets. Biofilm formation is a common concern during orthodontic treatment, as it can lead to oral health issues. Materials and Methods: The study utilized a randomized controlled trial design. The participants were divided into two groups: the experimental group and the control group. The experimental group received orthodontic brackets coated with nanoparticles, while the control group received regular brackets. The patients' oral hygiene was monitored, and plaque index scores were recorded at specific intervals. Results: The results of this study demonstrated a significant difference in biofilm formation between the two groups. The experimental group, which had orthodontic brackets with nanoparticle coatings, exhibited a lower plaque index compared to the control group. The mean plaque index score difference was statistically significant (P < 0.05), indicating that the nanoparticles effectively reduced biofilm formation on orthodontic brackets. Conclusion: In conclusion, the findings of this clinical study suggest that the utilization of nanoparticles as coatings for orthodontic brackets can be an effective approach to prevent biofilm formation.
