Laboratorial training of examiners for using a visual caries detection system in epidemiological surveys

BackgroundIn epidemiological surveys, a good reliability among the examiners regarding the caries detection method is essential. However, training and calibrating those examiners is an arduous task because it involves several patients who are examined many times. To facilitate this step, we aimed to propose a laboratory methodology to simulate the examinations performed to detect caries lesions using the International Caries Detection and Assessment System (ICDAS) in epidemiological surveys.MethodsA benchmark examiner conducted all training sessions. A total of 67 exfoliated primary teeth, varying from sound to extensive cavitated, were set in seven arch models to simulate complete mouths in primary dentition. Sixteen examiners (graduate students) evaluated all surfaces of the teeth under illumination using buccal mirrors and ball-ended probe in two occasions, using only coronal primary caries scores of the ICDAS. As reference standard, two different examiners assessed the proximal surfaces by direct visual inspection, classifying them in sound, with non-cavitated or with cavitated lesions. After, teeth were sectioned in the bucco-lingual direction, and the examiners assessed the sections in stereomicroscope, classifying the occlusal and smooth surfaces according to lesion depth. Inter-examiner reproducibility was evaluated using weighted kappa. Sensitivities and specificities were calculated at two thresholds: all lesions and advanced lesions (cavitated lesions in proximal surfaces and lesions reaching the dentine in occlusal and smooth surfaces).ResultsRegarding the reproducibility, the mean (range) of kappa values was 0.781 (0.529–0.927) for occlusal surfaces, 0.568 (0.191–0.881) for smooth surfaces, and 0.844 (0.698–0.971) for proximal surfaces. Considering all lesions, sensitivity and specificity mean values were respectively 0.724 and 0.844 for occlusal, 0.635 and 0.943 for smooth and 0.658 and 0.927 for proximal surfaces. For detecting advanced lesions, sensitivities and specificities were 0.563 and 0.920 for occlusal, 0.670 and 0.985 for smooth, and 0.838 and 0.985 for proximal surfaces.ConclusionThe methodology purposed for training and calibration of several examiners designated for epidemiological surveys of dental caries in preschool children using the ICDAS is feasible, permitting the assessment of reliability and accuracy of the examiners previously to the survey´s development.

Objective: To assess the dental caries prevalence with ICDAS II in the mixed dentition, 40 children aged 7 to 11 years old, participating in a social program, whose parents and/or guardians signed a informed consent form. Material and Methods: Clinical examination was carried out after brushing. A single researcher performed the examination and the diagnosis consistency was obtained by Kappa coefficient in 12% of the sample. All dental surfaces were examined receiving a two-digit code. The first one refers to the presence of restoration/sealant and the second, the severity of carious lesions. The data was processed at SPSS software version 10.0 and analyzed using descriptive statistics (absolute distribution, percentage, mean and standard deviation). Results: The coefficient intra-examiner agreement was 0,83. Caries prevalence was considered high because 100% of the children had some surface with non-cavitated caries lesion. ICDAS II can be easily transformed to dmf-s or DMF-S without compromising its integrity. For dmf-s/DMF-S decayed surfaces were considered ICDAS codes 3 to 6, resulting in a dmf-s = 6,57 where 11 children (27,5%) presented no decayed deciduous teeth surface. DMF-S = 2,0 showed that 15 children (37,5%) had none decayed permanent surface, determining a underestimation of the caries disease when using dmf-d/dmf-s and DMF-S indexes. Conclusion: A careful viewing of initial caries lesions makes ICDAS II usefull in evaluating the health promotion actions impact, supporting the planning process, implementation and evaluation of program activities.

“…For this reason, it is recommended to "wait and watch" and not to immediately "drill and fill" teeth 25 . According to Novaes et al 17 , visual inspection alone seems to be sufficient to detect dental caries satisfactorily. The results from CL1 and CL2 exams corroborate that statement in some degree.…”

Aim: To evaluate the performance of dental caries detection when adjunct methods are associated and their applicability in epidemiological survey of dental caries, at D3 (cavitated carious lesions at dentin layer) and D1+D3 (non cavitated and cavitated carious lesions at enamel/dentin layer) diagnostic thresholds. Methods: A total of 2189 posterior teeth from 165 12-year-old schoolchildren underwent visual examination without (CL1) and with artificial lighting (CL2), radiographic bitewing (BW), fiber-optic transillumination/FOTI (FT), DIAGNOdent TM (DD) and associations of these methods. Reproducibility was calculated by Kappa statistics and validity was calculated by sensitivity, specificity and accuracy tests. ANOVA (Scott-Knott test) was performed in order to compare the average values of DMF-S obtained by the diagnostic methods. Results: The CL2FTDDBW (D3) and CL2BW (D1+D3) exams presented the highest values for accuracy at epidemiological setting. The DMF-S index obtained for those exams was statistically different at D3 and D1+D3 thresholds. Conclusions: The association of adjunct methods increased the validity of dental caries examination in an epidemiological setting. However, the potential of CL2BW (traditional caries detection methods) or visual exam performed under a more refined diagnostic criteria must be considered in dental caries epidemiological surveys.

Performance of fluorescence‐based and conventional methods of occlusal caries detection in primary molars – an in vitro study

Abstract: Although fluorescence-based and conventional methods present similar performance in detecting occlusal caries lesions in primary teeth, visual inspection alone seems to be sufficient to be used in clinical practice.
