Assessing near infrared optical properties of ceramic orthodontic brackets using cross-polarization optical coherence tomography.

Secondary decay (caries) under ceramic orthodontic brackets remains a significant dental problem and near infrared cross-polarization optical coherence tomography (CP-OCT) has the potential to detect underlying demineralization. The purpose of this study was to determine the effect of crystalline structure and chemical composition of ceramic brackets on CP… CONTINUE READING
