Application and Future Utilization of Shellac in Orthodontics: A Systematic Review.

ABSTRACT

Background: This review examines the application of shellac in orthodontics, focusing on its properties, advantages, and potential as an alternative to conventional materials. In orthodontics, where bond strength, ease of application, and removal are paramount, shellac's capabilities meet these needs while supporting environmentally friendly practices. Methods: With objectives centered on evaluating shellac's effectiveness, biocompatibility, and impact on patient outcomes, a comprehensive search across multiple databases was conducted, including PubMed, Scopus, and Web of Science. This study's selection criteria targeted studies assessing shellac's use in orthodontic applications, measuring treatment effectiveness, biocompatibility, and patient satisfaction while excluding those not directly involving orthodontic applications or lacking empirical data. Results: Through a qualitative synthesis of the extracted data-encompassing study design, sample size, treatment outcomes, and adverse effects-the findings reveal shellac's potential benefits in orthodontics, such as enhanced patient comfort and comparable treatment outcomes to traditional materials. However, the review also notes variability in study designs and outcomes, indicating the need for further research. Conclusions: This study concluded that shellac presents a promising alternative in orthodontic materials, recommending additional studies to standardize assessment methodologies and confirm its long-term advantages.
