“…While the findings of this study support those of other recent studies [Poorterman et al, 2002;Hopcraft and Morgan, 2005;Lillehagen et al, 2007;Chu et al, 2008] in respect of the general underestimation of carious lesions where radiographic diagnosis is not used, they build on those studies in the presentation of more detailed data on its nature and intra-oral distribution (as represented by the information in table 3 ). That the discrepancy was considerably greater for approximal surfaces than for occlusal surfaces both confirms and extends earlier findings and again underlines the need for bitewing radiographs to be a routine part of oral epidemiological surveys (and, of course, the clinical management of patients) wherever logistics and funding permit.…”

The study aimed to determine the relative contributions of bitewing radiography and clinical examination to caries estimates for a New Zealand child population with high caries experience. An epidemiological survey was conducted of 171 12- and 13-year-old children attending schools in five communities. Examinations were conducted in dental clinics. Bitewing radiographs were taken at the time of the clinical examination. These were developed and read later, and the data from those were used at the analysis stage to adjust the caries diagnosis for the mesial, occlusal and distal surfaces of the posterior teeth. For almost all parameters, the use of radiographs resulted in higher estimates, although at the whole-mouth prevalence level the difference was not great. The percent difference between the estimates ranged from –0.1 to 166.7%. There were moderate differences between the clinical-only and radiographically adjusted whole-mouth estimates for mean DMFT, DT, DMFS and DS, but only a minor difference in caries prevalence. With the mesial and distal surfaces only, the prevalence and severity estimates were significantly greater, with a one-surface difference (on average) in mean DS being the largest difference observed, at 166.7%. The diagnostic discrepancy was much greater for approximal than occlusal surfaces. These findings support but also build upon earlier findings and again underline the need for bitewing radiographs to be a routine part of oral epidemiological surveys wherever logistics and funding permit.

“…13 In everyday clinical practice, radiographic evaluation is usually limited to teeth in doubt for caries or routinely carried out in subjects at high risk of caries, increasing the probability of detecting a lesion, leading to a high specificity and low sensitivity. 25 Instead, the near-infrared light transillumination might be used routinely over all surfaces particularly approximal surfaces, with no side effect, with an estimated high sensitivity.…”

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 5 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 5 0.91). At the dentinal level, the two methods identified the same number of caries lesions (kappa 5 1), whereas more approximal lesions were recorded using the transillumination device in the enamel (kappa 5 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.

“…One conventional diagnostic method relies on the radiolucency of hidden caries, which makes it detectable in a radiograph. Indeed, a clinical study of 200 young adults found that clinical evaluation with bitewing radiographic examination detected 106% more caries, mainly in the proximal surfaces, in the posterior permanent teeth than by clinical evaluation alone [8], which suggested that the detection rate of hidden caries depends on the prevalence of caries in the population and the frequency of bitewing radiographic examinations [24]. Although routine use of bitewing radiography could help identify teeth with hidden caries to allow early and conservative treatment, it is inaccurate in diagnosing occlusal enamel caries [19], and its detection rate for occlusal lesions is less than 50% of that for histological sectioning [30].…”

We studied the in vivo validity of dentinal fissure caries diagnosis by visual examination, bitewing radiography, and use of a laser-induced fluorescence device (DIAGNOdent). A total of 144 and second molars with macroscopically intact occlusal surfaces in 41 Chinese young adults were examined visually, by bitewing radiography, and by DIAGNOdent. Visual examination after pit and fissure opening was used as the reference standard. The sensitivity and specificity of detecting caries that had extended into the dentin were, respectively, 0.89 and 0.44 by visual detection of opacity or discoloration after air drying, 0.13 and 1.00 by bitewing radiography to detect radiolucency extending into the dentin, and 0.70 and 0.84 by DIAGNOdent testing with a cut-off score of 40. Caries detection by a combination of visual examination and DIAGNOdent had a sensitivity of 0.67 and specificity of 0.94. Receiver operating characteristic analysis showed that this combined approach was superior to the other methods.
