Evaluation of Optical Coherence Tomography in Dentistry

Status Recruiting

Clinical Trial Summary

Optical coherence tomography (OCT) is a medical diagnostic tool, providing non-invasive, non-radiative and high resolution imaging. OCT has been established since many years in ophthalmology. In dentistry the diagnostic potential of OCT is currently increasingly being noticed. This clinical study includes two individual trials: (i) Longitudinal assessment of surface sealant thickness using optical coherence tomography and (ii) comparison of crevicular fluid levels of inflammatory cytokines after the application of surface sealants.

Clinical Trial Description

Trial 1: Evaluation of the abrasion behavior of the orthodontic surface sealants Pro Seal®, Opal®Seal, and Protecto®CaF2Nano. The quadrants of 20 participants will be randomly assigned to four study groups. Using a split mouth design three commonly used orthodontic surface sealants (Pro Seal®, Opal®Seal, and Protecto®CaF2Nano) and a bonding primer (Transbond XT) which is used as a control will be applied to the labial surfaces of the teeth of the respective quadrants. The thickness changes of the orthodontic surface sealants and the development of enamel demineralization will be monitored at the day of the application and five additional time points (t1= 1 month, t2= 3 months, t3= 6 months, t4=9 months, t5= 12 months) using OCT.

Trial 2: Evaluation of Adverse effects of orthodontic surface sealants. 15 quadrants of the trial group described above (Trial1) will be randomly selected and gingival crevicular fluid (GCF) will be sampled in the respective quadrants at the day of bracket bonding prior (t0) and at three additional time points (t1= 30 min, t2= 60 min, t3= 90 min) after the application of surface sealants or the bonding primer, respectively. Analysis will be performed using magnetic Luminex screening assays for IL-8 (Interleukin 8), and IL-10 (Interleukin 10) and examined for inflammatory cytokines after the application of surface sealants. ;
