“…A separate value for any one of these parameters does not supply signifi cant information on the method of diagnosis in question [Thylstrup and Fejerskov, 1994]. Later studies [Noar and Smith, 1990;Nuttall and Pitts, 1990;Lazarchik et al, 1995] found that the more experienced the professional, the greater the ability to detect absence of lesion (specifi city); as a result, the choice for a restorative treatment was more careful. A possible explanation may be that the increasing knowledge of the etiology, initiation, progression and prevention of caries disease [Dodds, 1993;Basting and Serra, 1999] and the repetitive restorative cycle [Elderton, 1983] prompted a change of attitude with respect to the diagnosis of early caries lesions that resulted in more conservative treatment options.…”

Validity and Reproducibility of Different Combinations of Methods for Occlusal Caries Detection: An in vitro Comparison

This study assessed the validity and reproducibility of different combinations of occlusal caries detection methods: visual examination (VE), laser fluorescence (LF) and radiographic examination (RE). Intra- and interexaminer reproducibilities were also assessed. Forty-seven extracted human molars were used and 121 sites, either suspected or not to be carious, were chosen. Occlusal surfaces were examined by 8 volunteers, assigned to three groups according to their level of knowledge and clinical experience on dental practice: group I, undergraduate students; group II, postgraduate students; group III, professors. Three combinations of methods were tested: A: VE + LF, B: VE + RE, C: VE + LF + RE. The examiners scored the sites using ranking scales and chose a final score based on their clinical experience. The gold standard was determined by histological examination of the sites. In general, LF and RE yielded poorer results than the combinations of methods. For combination A, group III showed the highest sensitivity, while group II showed the highest specificity. For combination B, group II showed moderate sensitivity whereas groups I and III exhibited low sensitivities; all groups of examiners reached substantial specificity. For combination C, all groups exhibited moderate sensitivity and substantial specificity. Interexaminer reproducibility ranged from fair to moderate for combinations A and C, while for combination B kappa values indicated moderate interexaminer reproducibility. It may be concluded that individual exams presented inferior performance than the conjunction of them. Combination C (VE + LF + RE) resulted in the best accuracy for all groups. The knowledge background of the examiners influenced their ability to detect caries lesions and affected interexaminer reproducibility.

“…populations with decreased caries prevalence, the proportion of occlusal caries has increased and the diffi culty of accurately detecting incipient pit-and-fi ssure lesions has been continuously discussed, reinforcing the interest for studying this type of carious lesion [Creanor et al, 1990;Dodds, 1993;Lazarchik et al, 1995;Lavaonius et al, 1997].…”

“…The results obtained could be in part explained by Bader and Shugars's explanations, and partly by other factors such as age, training, skills, preferences and experiences of students and professionals, as described in Lazarchik et al 24 . In this regard, Héllen-Halme and Petersson 25 evaluated how variations in educational level and experience inf luenced diagnostic accuracy for the detection of approximal carious lesions.…”

Diagnostic agreement between radiologists, dentists and dental students for radiographic detection of approximal caries. Abstract: Aim: To assess intraobserver and interobserver agreement for radiographic detection of approximal caries among radiologists, dentists and senior dental students. Materials and methods: 75 standardized bitewing radiographs were examined by four maxillofacial radiologists, four dentists and four senior dental students. Iinterobserver agreement was calculated using a weighted Kappa Cohen test. Two weeks later, the examiners re-evaluated 10% of the sample under the same conditions and intraobserver agreement weighted Kappa Cohen test was calculated. Results: The interobserver Kappa value was 0.68 (good) for the dentist-student pair, 0.51 (moderate) for the student-radiologist and 0.62 (good) for the dentist-radiologist pair. All these differences were significant. The intraobserver agreement Kappa values obtained were 0.56 (moderate) for students (p=0.46), 0.46 (moderate) for dentists (p<0.05) and 0.68 (good) for radiologists. Conclusion: The agreement for proximal caries detection by dental students, dentists and radiologists was moderate to good.

“…Other studies have evaluated whether education level and experience can affect diagnostic accuracy of caries lesions in radiographs (Lazarchik et al, 1995;Mileman & van den Hout, 2002;Hellen-Halme & Petersson). Hellen-Halme & Petersson reported that experienced dentists diagnosed radiographic proximal caries more accurately than dental hygiene students and dentistry students.…”

Odontostomat., 11(3):347-352, 2017. ABSTRACT:The purpose of this study was to investigate the accuracy and interobserver reliability of examiners with different levels of clinical experience, when diagnosing radiographic proximal caries lesions. Bitewing radiographs were selected from a patient attending Operative Dentistry Clinic, Universidad de Chile. Radiographic examination was performed by three different groups: A: third year dentistry students, B: fourth year dentistry students, and C: dentist recently graduated. Thirty-two proximal surfaces were scored as: 0, sound; 1: enamel caries; and 2: dentinal caries. The data were analysed and accuracy and interexaminer reliability were calculated. Accuracy values for enamel caries were: A (0.54), B (0.55) and C (0.58), and dentinal caries were: A (0.55), B (0.61) and C (0.63). Interexaminer reliability denoted marginal agreement for all groups, A (0.249), B (0.213) and C (0.282) for enamel caries and A (0.058), B (0.102), and C (0.344) for dentinal caries. The results of this study indicate that the accuracy and interexaminer reliability of bitewing radiographic examination were influenced by the clinical experience when detecting radiographic proximal caries, however low values of accuracy and interexaminer reliability were noted, reinforcing the necessity of improving education and training in radiographic caries detection.
