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 .
Changes in white spot lesions following post-orthodontic weekly application of 1.25 per cent fluoride gel over 6 months—a randomized placebo-controlled clinical trial. Part I: photographic data evaluation
Background White spot lesions ( WSLs ) are a frequent side-effect of multibracket appliance treatment . The effect of local fluoridation on post-orthodontic WSL is however inconclusive . Objective Assessment of WSL changes in response to weekly 1.25 per cent fluoride gel application after multibracket appliance treatment . Trial design R and omized , single-centre , double-blind , parallel-group , placebo-controlled study . Participants Patients with not less than 1 WSL ( modified score 1 or 2 ) on not less than 1 upper front teeth after debonding . Interventions Professional fluoride/placebo gel application during weeks 1 - 2 ; self-administered home application ( weeks 3 - 24 ) . Outcomes Photographic WSL assessment ( dimension and luminance ) of the upper front teeth ( T0-T5 ) . R and omization R and om assignment to test ( n = 23 ) or placebo group ( n = 23 ) using a sequentially numbered list ( r and om allocation sequence generated for 50 subjects in 25 blocks of 2 subjects each ) . Recruitment The clinical study duration lasted from March 2011 to September 2013 . Blinding Unblinding was performed after complete data evaluation . Numbers analysed Intent-to-treat analysis set comprising 39 participants ( test : n = 21 , placebo : n = 18 ) . Outcome Dimensional WSL quantification showed limited reliability . Luminance improvement ( % ) of WSL , however , was seen after 6 months ( test/placebo : tooth 12 , 24.8/18.0 ; tooth 11 , 38.4/35.4 ; tooth 21 , 39.6/38.3 ; and tooth 22 , 15.2/25.0 ) . No statistically significant group difference existed . Data suggest that WSLs are difficult to measure with respect to reliability and repeatability and methods for monitoring WSLs in clinical trials require improvement/validation . Harms Similar adverse events occurred in both groups ; none was classified as possibly related to the study product . Limitations The number of dropouts was higher than expected and the socio-economic status was not assessed . Furthermore , the unknown level of compliance during the home application phase must be considered as limitation . Conclusion Based on the results of this study , no difference could be detected with respect to the development of WSL under post-orthodontic high-dose fluoride treatment . Registration The study was registered with Clinical Trials.gov ( Identifier : NCT01329731 ) . Protocol The protocol was n't published before trial commencement
