OBJECTIVES: This 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. METHODS: Two 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. RESULTS: A 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 participants.
CONCLUSIONS: 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 detection.
