OBJECTIVES: To clinically validate the use of a modified image receptor-holding device (IRHD) for the bitewing technique.
METHODS: Premolars and molars' bitewing radiographs of 101 patients were acquired using 2 IRHD (traditional and modified). The modified IRHD was computer-aided designed and 3D printed. Images were acquired by a single operator using a digital radiographic system with phosphor storage plates. A questionnaire regarding the perception of the use of the 2 IRHD was applied to patients and the operator. Image evaluation (paired and individual) was performed by 2 oral and maxillofacial radiologists. Repetition, overlap rate, and operator/patient perception were expressed as absolute and relative frequencies, and compared between the devices using the chi-square test with a 5% significance level.
RESULTS: The paired evaluation showed no difference in the rate of proximal surface overlap between the IRHDs (P ≥ .05). Individual evaluation showed a lower rate of proximal surface overlap with the modified IRHD, with emphasis on the distal surface in the premolar region (P < .05). The modified IRHD presented greater ease of positioning (52.3%), greater stability (64.9%), preference of use by the operator (54.5%), and greater comfort was reported by the patients (54.5%).
CONCLUSIONS: The modified IRHD may be more comfortable and has the potential to reduce the proximal surface overlap than the traditional IRHD, especially when there is an indication for a single radiograph in the premolar region.
ADVANCES IN KNOWLEDGE: We clinically validated a modified IRHD that has potential to decrease proximal surfaces overlap with greater comfort for the patients.
