Abstract Objectives To investigate the influence of orthodontic materials on the assessment of proximal caries using periapical radiography. Methods Forty non-cavitated and restoration-free human premolars and molars ranging from sound teeth to teeth containing various grades of lesions were embedded with approximal contacts into silicon blocks. Periapical radiographs were obtained using combinations of two orthodontic materials (three bracket and two archwires). Images were obtained using a Planmeca ProX™ (Planmeca®, Helsinki, Finland). Two observers assessed the images. Intraobserver and interobserver agreement was computed using an intraclass correlation coefficient. Receiver operating characteristic (ROC) analysis was used to calculate the true positive value, true negative value, and the area under the ROC curve (AUC). Results Intraobserver agreement ranged from 0.483 to 0.768. Interobserver agreement ranged from 0.383 to 0.718. The AUC, sensitivity and specificity were 0.792, 71.23% and 87.10% in the control group (without bracketing), respectively. The highest area under the curve (AUC) value (0.792) was obtained from the without bracket group. The lowest AUC value (0.659) belonged to the stainless steel bracket and steel wire group. A decrease in the AUC values was observed for the control group (without bracketing) compared to the stainless steel bracket and steel wire group (P = 0.040). Conclusions The addition of a stainless steel bracket with stainless steel wire combination makes it difficult to the diagnose the interproximal tooth caries by periapical radiography.

Introduction Dental caries is a prominent worldwide common health problem. Early diagnosis is principal for the foundation of a suitable treatment plan as conservative as practicable, diminishing the involvement of tooth structures in restorative methods, when noticed [1]. In addition to this, the finding out of small lesions, principally on occlusal surfaces, is yet difficult for the dental specialist [2]. The complexity of exact detection is related to factors such as the complex anatomy of fissures and pits [3], superposition of structures in the radiographic assessment, and increase in the number * Ozlem Isman [email protected] 1
