RESUMO

The world development pattern of dental caries disease has increased the complexity of carious lesions diagnosis especially in occlusal surfaces by the visual-tactile exam, constituting one of the great challenges of the Public Health Dentistry. The aim of this study was to verify the reproducibility (intra and interexaminer Kappa [к] statistics) and the validity (area under the ROC curve [AZ]) of the "artificial illumination" (CL2), "bitewing radiographs" (BW), "transillumination by FOTI" (FT) and "laser fluorescence examination (DIAGNOdent®) " (DD), adjunct technologies of dental caries diagnosis, separately or in association with the visual-tactile exam (CL1), under epidemiological settings and WHO (D3) and WHO+IL (D1) diagnostic criteria. Concerning the reproducibility, 1 standard and 3 experienced examiners examined 13 schoolchildren (twelve-years-old) enrolled in public schools from Piracicaba, SP. The reproducibility sample were randomly selected and presented low to high dental caries prevalence. In relation to the validity, 1 standard and 1 experienced examiner examined 165 twelve-years-old schoolchildren that presented the same characteristics of the reproducibility sample. The (intra/interexaminer) reproducibility, for dental surfaces, under the D3 and D1 diagnostic criteria, was almost perfect for the CL1 (D3: кintra=0.91/кinter=0.85; D1: кintra=0.89/кinter=0.84), CL2 (D3: кintra=0.91/кinter=0.85; D1: кintra=0.88/кinter=0.83), BW (D3: кintra=0.95/кinter=0.92; D1: кintra=0.99/кinter=0.90) e FOTI (D3: кintra=0.97/кinter=0.93; D1: кintra=0.87/кinter=0.83) examinations and it was fair for the DD (D3: кintra=0.36/кinter=0.35; D1: кintra=0.30/кinter=0.32) examination. The diagnostic technologies associations, CL2+FT+DD+BW (AZ-D1=0.8541; AZ-D3=0.6963), for occlusal + approximal surfaces, CL2+DD+BW (AZ-D1=0.8187; AZ-D3=0.6650), for occlusal surface, and CL2+FT+BW (AZ-D1=0.7234; AZ-D3=0.6836), for approximal surfaces, presented the largest validity under the D1 and D3 diagnostic criteria, respectively. It was concluded that the CL1, CL2, FT and BW examinations present a reproducibility compatible with the execution of epidemiological surveys of dental caries, and that the CL2+FT+DD+BW, CL2+DD+BW and CL2+FT+BW technologies associations are the best methods of examinations for occlusal + approximal surfaces, occlusal surfaces and approximal surfaces under D1 and D3 diagnostic criteria in epidemiological settings respectively.
