Abstract

Aim: The primary objective of this systematic review is to evaluate and compare the incidence of white spot lesions between clear aligner and fixed Orthodontic therapy. Materials and methods: Randomized clinical trials of parallel, block randomisation, computer based and stratified randomisation and split-mouth design, involving patients undergoing Orthodontic treatment are considered. Studies had to compare the WSLs and periodontal health between CA and FA groups were searched in the electronic databases PubMed and Cochrane Library. A summary of the overall strength of evidence available was assessed using the Grades of Recommendations Assessment. Data collection: A total of 51 records were found, from which only 4 articles met the inclusion criteria and were subjected to analysis. Results: Majority of the studies included in this review have positively correlated a potential decrease in WSLs and better periodontal health with the use of clear aligners. However, most of the studies lack a long-term duration and follow up. Conclusion: More clinical trials in this area are welcome in order to have a better conclusion in terms of which appliance therapy would provide optimal dental and periodontal health during and after Orthodontic therapy.
