Conclusion Costs for repeated treatment of post-orthodontic enamel damages produced by conventional vestibular fixed appliances may easily exceed the initially higher costs associated with lingual orthodontic treatment .
Judged economically in the long term , lingual MB Tx may be considered as a more cost-effective solution for a correction of malocclusion
Background Post-orthodontic white-spot lesions ( WSL ) in esthetically relevant incisor and canine areas impair dentofacial esthetics , and preventive dentistry treatment is definitely required in case of enamel cavitations .
The incidence of lingual post-orthodontic WSL and cavitation following lingual MB treatment has been reported to be distinctively decreased compared to labial MB treatment .
Moreover , lingual WSL do not impair dentofacial esthetics .
It was the objective of this study to calculate consequential costs of preventive dental care necessary to recover labial or lingual post-orthodontic cavitations as well as esthetically relevant WSL following either labial or lingual MB interventions .
Efficacy of a fluoride-releasing orthodontic primer in reducing demineralization around brackets: an in-vivo study.
INTRODUCTION A new , highly filled primer is currently marketed as a fluoride delivery system effective in reducing white spot lesions in orthodontic patients . However , no studies in the literature support this cl aim . The purpose of this in-vivo study was to investigate the retention and the efficacy of this primer in reducing the formation of white spot lesions . METHODS In each patient for whom premolar extraction s were planned ( n = 22 ) , 1 premolar was r and omly chosen as the experimental tooth for the application of the fluoride delivery system ( Opal Seal ; Ultradent Products , South Jordan , Utah ) , and the contralateral tooth was assigned as the control to receive the st and ard treatment ( Transbond XT ; 3 M Unitek , Monrovia , Calif ) . After the bonding procedures , separators were placed around the premolar brackets to encourage plaque retention over 8 weeks . After the extraction s , the tooth surfaces were evaluated visually and with microhardness techniques for demineralization . Primer retention was also investigated . RESULTS There were no statistically significant differences in the numbers of white spot lesions between the 2 groups . The primer retention was calculated as 50 % . CONCLUSIONS The results indicated no significant difference between the efficacies of the fluoride-releasing primer and the control primer in reducing demineralization over the duration of the study
Conclusion Costs for repeated treatment of post-orthodontic enamel damages produced by conventional vestibular fixed appliances may easily exceed the initially higher costs associated with lingual orthodontic treatment .
