The impact of different dental restorations on detection of proximal caries by cone beam computed tomography.

Objectives: To evaluate the effects of different types of restorations on observer ability to detect proximal caries in CBCT images.

Materials And Methods: Forty human premolars and molars with artificial proximal caries were placed proximal and distal to 5 molars having different restorations (amalgam, composite, resin-modified glass ionomer cement (RMGIC) fillings, zirconia, and lithium disilicate crowns) and a non-restored molar. CBCT scans were obtained using i-CATNext Generation.

Intraoral versus extraoral bitewing radiography in detection of enamel proximal caries: an ex vivo study.

Objective: To compare the diagnostic accuracy of digital intraoral and extraoral bitewing (EO BW) radiography in the detection of enamel proximal caries regardless of their ability to separate contacts.

Methods: Artificial caries with different degrees of decalcification was induced in 80 human sound premolars and molars using formic acid. Intraoral radiographs were taken with photostimulable phosphor plate (PSP) and complementary metal oxide semiconductor (CMOS), using the paralleling bitewing technique.
