Comparative study of the radiologic diagnosis of proximal caries lesions using conventional and direct digital techniques. Rev. Estomatol. Herediana [online]. 2016, vol.26, n.2, pp.63-69.

Objectives: Compare the radiologic diagnosis of proximal caries lesions using conventional bitewing technique and direct digital charge-coupled device using a database with diagnostic records. Materials and Methods: There were evaluated the radiographic diagnostic database of 108 teeth (50 molars and 58 premolars) with 106 mesial and 100 distal carious surfaces. This database consists of proximal caries diagnosis in R0, R1, R2, R3 and R4; Pitts made by classification modified by Universidad Peruana Cayetano Heredia. The agreement was got in the diagnosis by testing Kappa coefficient was p<0.01. The study had a significance of 95% and p <0.05. Results: According to the conventional bitewing technique was found a 53.9% of R0, 22.3% of R1, 7.8% of R2, 11.2% of R3, and 4.9% of R4 and direct digital charge-couple device technique was found a 52.9% of R0, 14.6% of R1, 11.7% of R2, 14.6% of R3, and 6.3% of R4. Conclusions: There is a difference in the radiographic diagnosis of interproximal caries lesions using both techniques. However, it can not affirm the superiority of some of them for lack of histological gold standard.
