(1)[181]Koprowski et al.Automatic method of analysis of OCT images in the assessment of the tooth enamel surface after orthodontic treatment with fixed bracesThis paper presents an automatic quantitative method for the assessment of tooth enamel thickness captured on the OCT scans. This method has proven to be an effective diagnostic tool that allows evaluation of the surface and cross section of tooth enamel after orthodontic treatment with fixed thin-arched braces and proper selection of the methodology and course of treatment.

(2)[182]Seeliger et al.Enamel thickness before and after orthodontic treatment analysed in optical coherence tomographyThe range of variations in the enamel thickness after treatment with fixed thin-arched braces is not subjected to modification of a factor such as the type of adhesive system. The OCT is an effective diagnostic tool to evaluate the thickness of the enamel tissue before and after the completed orthodontic treatment.

(3)[183]Pithon et al.Effectiveness of fluoride sealant in the prevention of carious lesions around orthodontic brackets: an OCT evaluationPro Seal sealant alone or combined with brushing and/or brushing and the use of a mouthwash with fluoride was more effective in protecting enamel, in comparison to brushing alone.

(4)[184]Leão Filho et al.Enamel quality after debonding:
evaluation by optical coherence tomography
The results demonstrated that enamel fractures were observed only in the samples bonded with ceramic brackets, and the type of pliers did not influence the incidence and extent of enamel damage. Moreover, the type of debonding technique (with side-cutting pliers or anterior bracket removal pliers) and the type of bracket did not influence the amount of adhesive remaining after debonding. The burs at low speed removed the remaining adhesive more effectively during cleanup procedures.

(5)[185]Pithon et al.Effectiveness of varnish with CPP–ACP in prevention of caries lesions around orthodontic brackets: an OCT evaluationThe major limitation of this study is that it is a study in which demineralization was obtained with the use of chemical products and did not occur due to the presence of Streptococcus mutans and its acid byproducts. Application of CPP-ACP-containing varnish irrespective of being associated with brushing and mouthwash, or not, reduced depth of caries lesions around orthodontic brackets.

(6)[186]Nee et al.Longitudinal monitoring of demineralization peripheral to orthodontic brackets using cross polarization optical coherence tomographyCP-OCT was able to measure a significant increase in demineralization (P < 0.0001) at the base of orthodontic brackets over a period of 12 months.

(7)[187]Isfeld et al.Assessing near infrared optical properties of ceramic orthodontic brackets using cross-polarization optical coherence tomographyNoninvasive, near infrared (NIR) cross-polarization optical coherence tomography (CP-OCT) has potential to effectively image through portions of ceramic brackets; however, further investigation into the optical effects of resin integration in the base portion of the brackets is warranted.

(8)[188]Leão Filho et al.Optical coherence tomography for debonding evaluation: an in-vitro qualitative studyThe analysis of the two-dimensional and three-dimensional images allows observation and evaluation of adhesive remnants, enamel damage, and superficial aspects of enamel from different methods of adhesive remnant removal. The 2D optical coherence tomography analysis allows in-depth observation of the adhesive remnant layer. Optical coherence tomography can be a powerful tool for academic and clinical applications for the evaluation of debonding procedures.
