article aimed to evaluate: (a) the agreement between a near-infrared
light transillumination device and clinical and radiographic
examinations in caries lesion detection and (b) the reliability of
images captured by the transillumination device.
calibrated examiners evaluated the caries status in premolars and
molars on 52 randomly selected subjects by comparing the
transillumination device with a clinical examination for the occlusal
surfaces and by comparing the transillumination device with a
radiographic examination (bitewing radiographs) for the approximal
surfaces. Forty-eight trained dental hygienists evaluated and
reevaluated 30 randomly selected images 1-month later.
high concordance between transillumination method and clinical
examination (kappa = 0.99) was detected for occlusal caries lesions,
while for approximal surfaces, the transillumination device identified a
higher number of lesions with respect to bitewing (kappa = 0.91). At
the dentinal level, the two methods identified the same number of caries
lesions (kappa = 1), whereas more approximal lesions were recorded
using the transillumination device in the enamel (kappa = 0.24). The
intraexaminer reliability was substantial/almost perfect in 59.4% of the
transillumination method showed a high concordance compared with
traditional methods (clinical examination and bitewing radiographs).
Caries detection reliability using the transillumination device images
showed a high intraexaminer agreement. Transillumination showed to be a
reliable method and as effective as traditional methods in caries
