Purpose: To determine if biostimulation using a 810 nm diode laser was capable of affecting the rate of extraction space closure during orthodontic treatment. Materials and methods:Forty dental arches of patients above 17 years of age requiring bilateral first premolar extractions were exposed to a 810 nm diode laser with a power density of 3.97 W/cm 2 at 3 weeks intervals for total duration of 12 weeks during the space closure phase under direct anchorage using miniscrews. Space closure measurements were taken using digital calipers and the unpaired t-test was used to compare the differences between the experimental and control sides. Results:The rate of orthodontic tooth movement was greater on the experimental side and the difference between the two sides was statistically significant (p < 0.001). Conclusion:Biostimulation carried out using a 810 nm diode laser is capable of increasing the rate of extraction space closure in humans. Hence, it can be concluded that it is capable of increasing the rate of orthodontic tooth movement.

“…In DIAGNOdent 2095, the light is transported to the angulated tip through a central fiber while fluorescence light is collected through additional fibers that are concentrically arranged around this central fiber. Results of in vivo 13,15 and in vitro 11,12,16 studies in permanent teeth have shown that this new model has better sensitivity but worse specificity than the previous one on occlusal surfaces and that the validity of the device to detect caries in relation to their lesion depth was very good.…”

“…A new model, DIAGNOdent Pen (DIAGNOdent 2190, KaVo, Bibberach, Germany), with smaller-diameter tips has been developed for fissured, smooth, and approximal surface caries detection. [11][12][13] The device emits a red laser beam at a wavelength of 655 nm (1 mW maximum power) and measures the lesion's fluorescence (at 720-750 nm), produced by microbial metabolic products, the porphyrins. 14 Although the device functions with the same principle as the old one, its main difference is at the tip, which is rotatable around its long axis to facilitate use in approximal areas.…”

“…Most of the validity values calculated in this study for DIAGNOdent Pen are within the range of previous studies, except for the sensitivity of enamel lesions, which was found to be much lower. 11,13,15,40 This may be attributed to parameters such as sample selection (eg, normal distribution of the selected teeth in the caries categories and exclusion of teeth with D4 lesions), storage techniques (eg, teeth stored in tap water and not frozen), specimen preparation techniques (eg, only rubber caps for cleaning), reference methods used, and differences in histological evaluation (no stains used).…”

Laser/light fluorescence devices were highly reliable for occlusal caries diagnosis in permanent teeth but not superior in accuracy to visual methods. SUMMARYPurpose: Current caries diagnostic tools are neither very accurate nor very reliable for the detection of carious lesions of different depths. Thus, the development of new devices and techniques is needed. The aim of this in vitro study was to validate a newer fluorescence device, VistaProof (VP), and compare it with DIAGNOdent Pen (DP), direct visual (DV) and indirect visual methods (IDV), with respect to accuracy and reliability for the detection of occlusal caries in permanent teeth.Methods and Materials: One hundred seven sites on 41 occlusal surfaces of recently extracted premolars were selected and classified into lesion categories according to Ekstrand's clinical criteria, by direct and indirect visual examination. The fluorescence of the sites was also measured by the two devices, and the teeth were ground through the sites for histological evaluation of their lesion depth. One calibrated examiner of high reliability (intraclass correlation coefficient [ICC].0.85) made all of the evaluations. Sensitivity, specificity, and accuracy of each detection method were estimated based on histological examination as the reference method, estimated using cutoff limits calculated on the basis of best agreement between the devices' values and histological examination. McNemar tests and receiver operating characteristic (ROC) curve , 2012, 37-3, 234-245 analyses were used to compare the validity measures of all detection methods at a=0.05, while the ICC was used to test the reproducibility of the methods based on a second measurement one week after the first.Results: There was no statistically significant difference (p.0.05) between the accuracy of DP and VPs for both enamel and dentin lesions. The areas under the ROC curves (AUC) for the two devices were also found not to be different (p.0.05). The reliability of DP was statistically significantly better than VP (p,0.05).Conclusion: The validity of both fluorescence devices were not found to be significantly different and not better than visual methods for the detection of noncavitated carious lesions.

“…A great number of studies deal with the development and the use of new technologies to improve the diagnosis of dental caries, especially at the early stages 5,[12][13][14][15][16][17][18][19] . Generally, such studies are performed under controlled conditions, in vitro (laboratory settings) or in vivo (clinical settings) methodology.…”

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.
