“…1214 Also, video prints of Trophy RVG III images are reported to be comparable to film for detecting occlusal and proximal surface caries. 15 Our work is also consistent with that of Heaven 16 and Dove 17 who found no significant difference in viewers' ability to detect caries on radiographs compared to viewing digitized radiographs displayed on a monitor. Others have found that holes drilled in proximal surfaces of teeth to simulate caries are better detected on film than with RVG III.…”

“…26 · 27 Both he and Heaven described software capable of identifying proximal surface caries with an overall accuracy comparable to clinicians. 16 Dentists' performance in caries diagnosis is improved with the assistance of such programs. 28 We anticipate that this line of work, currently in its infancy, will eventually mature and constitute a substantive advantage for the use of digital radiography.…”

“…The program made, however, fewer incorrect decisions to restore noncavitated surfaces than the practitioners [Firestone et al, 1998]. Moreover, the program seemed to be much more reproducible than observers with very little variation and high kappa scores [Duncan et al, 1995]. The 5 dentists in the present study were told that the LCD program is meant to provide a 'second opinion' in those cases where the dentist has doubt about the state of disease in a surface.…”

“…Heaven et al [1992Heaven et al [ , 1994 have developed such a program and evaluated it in laboratory studies on extracted teeth. The sensitivity of the program for caries detection was shown to be higher than that of clinicians and faculty members while specificity was higher for the human viewers [Duncan et al, 1995]. The program made, however, fewer incorrect decisions to restore noncavitated surfaces than the practitioners [Firestone et al, 1998].…”

The aim of this study was to evaluate a decision–support, caries detection program and its influence on observer agreement in caries diagnosis. 130 patients were examined by digital bitewing radiography (RVG XL sensor, Trophy Radiologie Inc.). Fifty–four approximal surfaces (27 in premolars and 27 in molars) were selected by the author: 24 surfaces (9 in molars and 15 in premolars) scored as sound, 16 surfaces (9 in molars and 7 in premolars) scored as carious in enamel, and 14 surfaces (9 in molars and 5 in premolars) scored as carious in dentine. The Logicon Caries Detector™ (LCD) program (Logicon Inc., USA) was assessed by repeating the automated analysis ten times for each surface. The two most varying outcomes for lesion probability (Lp_min and Lp_max) were saved. Five observers scored the 54 surfaces independently as sound, caries in enamel or caries in dentine before and after the use of LCD. In more than one third of all surfaces the program indicated different lesion probability, from sound at Lp_min to the presence of a carious lesion at Lp_max. The 5 observers changed their caries score after the use of LCD in a total of 31 surfaces (only 2 of these were in the same surface). Mean kappa value for inter–observer agreement for caries scores before the use of LCD was 0.47 (range 0.39–0.61) and after LCD 0.48 (range 0.37–0.69). It was concluded that the automated caries detection program was not very consistent and provided different opinions on the caries status in a surface. Inter–observer agreement in caries diagnosis did not improve using the program.

Effect of computer assistance on observer performance of approximal caries diagnosis using intraoral digital radiography

et al. 2009

Logicon Caries Detector (LDDC) is the only commercially available computer-assisted diagnostic system for caries diagnosis. The object of this study is to elucidate the efficacy of LDDC when used by inexperienced dentists. Fifty extracted teeth were imaged using an RVG6000. Seven dentists who had just passed the Japanese National Dental Board Examination observed those images without LDDC (woLDDC) and assessed the probability that caries lesions were present, then re-assessed the same teeth using LDDC (wLDDC). The areas under the receiver operating characteristic curves (Az) were compared. No statistically significant difference was found between woLDDC Az values and wLDDC Az values when caries lesions of all depths were considered. When positive cases were restricted to caries lesions in the inner half of the enamel or to dentine caries lesions, however, wLDDC Az values were significantly larger than woLDDC (p = 0.043 and 0.018, respectively).
