Photodiagnosis Photodyn Ther 2023; 44:103744. [PMID: 37567332 DOI: 10.1016/j.pdpdt.2023.103744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 07/11/2023] [Accepted: 08/08/2023] [Indexed: 08/13/2023]
Abstract
BACKGROUND This study compared the performance of near-infrared light transillumination (NILT; DIAGNOcam [DC]) in detecting occlusal caries lesions in deciduous molars with the performance of the International Caries Detection and Assessment System (ICDAS), digital radiographic method (RX) and laser fluorescence (DIAGNOdent pen [LFpen]). METHODS Fifty-seven extracted deciduous molars with no frank cavitation caries lesions were selected. One site per tooth was evaluated twice each by two examiners using all methods. Then, a histological examination was performed using a stereomicroscope. The performance of the methods was assessed with respect to two thresholds: D1 (all visible caries lesions affecting enamel) and D3 (caries lesions extended into dentin). RESULTS A weighted kappa and intraclass correlation coefficients were calculated for intra- and inter-observer reproducibilities, varying from 0.31 (RX) to 0.89 (LFpen). The intra-observer reproducibility at D1 and D3 thresholds varied from 0.51 (ICDAS) to 0.85 (DC) and from 0.30 (ICDAS) to 1.00 (RX), respectively. The inter-observer reproducibility varied from 0.28 (RX) to 0.47 (DC) and from 0.22 (LFpen) to 0.75 (DC), respectively. At the D1 threshold, higher sensitivity and accuracy were found for LFpen (0.76/0.71) and ICDAS (0.65/0.66); and higher specificities were found for RX (0.94), DC (0.79), and ICDAS (0.71). At the D3 threshold, all methods exhibited lower sensitivities (0.13-0.35) and higher specificity, accuracy, and area under the ROC curve values (0.70-1.00). All methods showed a correlation with histological results, especially for ICDAS and DC. CONCLUSIONS NILT technology (DC) and LFpen exhibited similar performance for the detection of occlusal caries lesions in deciduous molars when compared with ICDAS criteria.

Detection and localization of caries and hypomineralization on dental photographs with a vision transformer model. NPJ Digit Med 2023; 6:198. [PMID: 37880375 PMCID: PMC10600213 DOI: 10.1038/s41746-023-00944-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 10/13/2023] [Indexed: 10/27/2023] Open
Abstract
Caries and molar-incisor hypomineralization (MIH) are among the most prevalent diseases worldwide and need to be reliably diagnosed. The use of dental photographs and artificial intelligence (AI) methods may potentially contribute to realizing accurate and automated diagnostic visual examinations in the future. Therefore, the present study aimed to develop an AI-based algorithm that can detect, classify and localize caries and MIH. This study included an image set of 18,179 anonymous photographs. Pixelwise image labeling was achieved by trained and calibrated annotators using the Computer Vision Annotation Tool (CVAT). All annotations were made according to standard methods and were independently checked by an experienced dentist. The entire image set was divided into training (N = 16,679), validation (N = 500) and test sets (N = 1000). The AI-based algorithm was trained and finetuned over 250 epochs by using image augmentation and adapting a vision transformer network (SegFormer-B5). Statistics included the determination of the intersection over union (IoU), average precision (AP) and accuracy (ACC). The overall diagnostic performance in terms of IoU, AP and ACC were 0.959, 0.977 and 0.978 for the finetuned model, respectively. The corresponding data for the most relevant caries classes of non-cavitations (0.630, 0.813 and 0.990) and dentin cavities (0.692, 0.830, and 0.997) were found to be high. MIH-related demarcated opacity (0.672, 0.827, and 0.993) and atypical restoration (0.829, 0.902, and 0.999) showed similar results. Here, we report that the model achieves excellent precision for pixelwise detection and localization of caries and MIH. Nevertheless, the model needs to be further improved and externally validated.

Systematic review and meta-analysis on the effect of self-assembling peptide P 11-4 on arrest, cavitation, and progression of initial caries lesions. J Am Dent Assoc 2023:S0002-8177(23)00189-7. [PMID: 37245138 DOI: 10.1016/j.adaj.2023.03.014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Revised: 02/14/2023] [Accepted: 03/10/2023] [Indexed: 05/29/2023]
Abstract
BACKGROUND Simple noninvasive evidence-based interventions for caries are needed to overcome limitations in the restorative paradigm. The self-assembling peptide P11-4 is a noninvasive intervention that regenerates enamel in initial caries lesions. STUDIES REVIEWED The authors conducted a systematic review and meta-analysis on the effectiveness of the P11-4 products Curodont Repair (Credentis; now manufactured by vVARDIS) (CR) and Curodont Repair Fluoride Plus (Credentis; now manufactured by vVARDIS) on initial caries lesions. Primary outcomes were lesion progression after 24 months, caries arrest, and cavitation. Secondary outcomes were changes in merged International Caries Detection and Assessment System score categories, quantitative light-induced fluorescence (QLF; Inspektor Research System), esthetic appearance, and lesion size. RESULTS Six clinical trials met the inclusion criteria. Results of this review represent 2 primary and 2 secondary outcomes. When compared with parallel groups, use of CR likely results in a large increase in caries arrest (relative risk [RR], 1.82 [95% CI, 1.32 to 2.50]; 45% attributable risk [95% CI, 24% to 60%]; number needed to treat [NNT], 2.8) and likely decreases lesion size by a mean (SD) of 32% (28%). The evidence also suggests that use of CR results in a large reduction in cavitation (RR, 0.32 [95% CI, 0.10 to 1.06]; NNT, 6.9) and is uncertain about lowering merged International Caries Detection and Assessment System score (RR, 3.68 [95% CI, 0.42 to 32.3]; NNT, 19). No studies used Curodont Repair Fluoride Plus. No studies reported adverse esthetic changes. PRACTICAL IMPLICATIONS CR likely has clinically important effects on caries arrest and decreased lesion size. Two trials had nonmasked assessors, and all trials had elevated risks of bias. The authors recommend conducting longer trials. CR is a promising treatment for initial caries lesions. The protocol for this systematic review was registered a priori with PROSPERO (304794).

Abstract
A total 302 teeth (148 molars and 154 premolars) corresponding to 152 patients aged ≥18 years were evaluated for caries using the ICDAS (International Caries Detection and Assessment System), fluorescence (DD, DIAGNOdent) and electrical impedance (IMS, CarieScan PRO) systems. Fissurotomy and intraoral radiographs were used as the gold standard. Accordingly, 27.5% (n=84) of the teeth were classified as sound, while 26.9% (n=81) had enamel involvement and 45.6% (n=138) presented carious lesions reaching the dentin. Sensitivity (Se), specificity (Sp), and the area under the curve (AUC) were, respectively, 90.7%, 87.8%, and 0.954 (IMS); 92.4%, 92.7%, and 0.954 (DD); and 79.0%, 72.3%, and 0.756 (ICDAS). With regard to Se and Sp, there were significant differences between ICDAS and DD (p<0.001) and between ICDAS and IMS (p=0.01), but not between IMS and DD (p=0.07). In relation to AUC, there were significant differences between ICDAS and DD (p<0.001), and between ICDAS and IMS (p<0.001), but not between IMS and DD (p>0.05). The correlations between fissurotomy and each method were 88.7% (IMS), 89.7% (DD), and 77.1% (ICDAS). Within the limitations of this study, clinically, the electrical system is not useful for differentiating between sound teeth and truly incipient caries lesions by itself. The fluorescence or electrical systems are recommended with the ICDAS to detect carious lesions in their early stages.

Abstract
Although visual examination (VE) is the preferred method for caries detection, the analysis of intraoral digital photographs in machine-readable form can be considered equivalent to VE. While photographic images are rarely used in clinical practice for diagnostic purposes, they are the fundamental requirement for automated image analysis when using artificial intelligence (AI) methods. Considering that AI has not been used for automatic caries detection on intraoral images so far, this diagnostic study aimed to develop a deep learning approach with convolutional neural networks (CNNs) for caries detection and categorization (test method) and to compare the diagnostic performance with respect to expert standards. The study material consisted of 2,417 anonymized photographs from permanent teeth with 1,317 occlusal and 1,100 smooth surfaces. All the images were evaluated into the following categories: caries free, noncavitated caries lesion, or caries-related cavitation. Each expert diagnosis served as a reference standard for cyclic training and repeated evaluation of the AI methods. The CNN was trained using image augmentation and transfer learning. Before training, the entire image set was divided into a training and test set. Validation was conducted by selecting 25%, 50%, 75%, and 100% of the available images from the training set. The statistical analysis included calculations of the sensitivity (SE), specificity (SP), and area under the receiver operating characteristic (ROC) curve (AUC). The CNN was able to correctly detect caries in 92.5% of cases when all test images were considered (SE, 89.6; SP, 94.3; AUC, 0.964). If the threshold of caries-related cavitation was chosen, 93.3% of all tooth surfaces were correctly classified (SE, 95.7; SP, 81.5; AUC, 0.955). It can be concluded that it was possible to achieve more than 90% agreement in caries detection using the AI method with standardized, single-tooth photographs. Nevertheless, the current approach needs further improvement.

Negligible therapeutic impact, false-positives, overdiagnosis and lead-time are the reasons why radiographs bring more harm than benefits in the caries diagnosis of preschool children.

Abstract
Background To evaluate the clinical course and interventions required during two years of follow-up of dental surfaces of deciduous molars diagnosed, and consequently treated, by two different strategies: diagnosis made by clinical examination alone or associated with radiographs. Methods This is a secondary analysis of a two-arm randomized clinical trial with parallel groups related to the diagnostic strategy for caries detection in preschool children. 216 children (3–6 years old) were followed-up for two years. All dental surfaces were diagnosed by visual inspection and later, through radiographic assessment. Baseline treatment was made in accordance with the results obtained by visual inspection performed alone or combined with radiographic method, considering the allocated group. Dental surfaces with no restoration needs, or those restored at the beginning of the study were followed-up for two years. The treatment decision was made according to the allocated group. The outcome was the occurrence of failure (a new caries lesion or a restoration replacement) during the follow-up. Results 4383 proximal and occlusal surfaces of deciduous molars in 216 preschool children were diagnosed and treated according to the abovementioned diagnostic strategies and followed-up for 24 months. The assessment of radiographs made change the initial decision reached by visual inspection in about 30% of the surfaces when all types of interventions were considered. However, most disagreements occurred for initial lesions, where radiographs tended to underestimate them. Discordances between methods occurred in less than 5% of all surfaces when considered lesions requiring operative treatment. For discrepancy cases, the placed interventions guided by following the radiographic results did not present less failures against those made following only visual inspection. As a matter of fact, the use of radiographs in the diagnostic strategy for caries detection in children brought more harms than benefits due to the occurrence of false-positives, overdiagnosis and lead-time bias. Conclusions Simultaneous association of visual inspection and radiographic assessment for caries detection in preschool children causes more harms than benefits, and therefore, visual inspection should be conducted alone in the regular clinical practice.

Clin Oral Investig 2021; 25:3977-3986. [PMID: 33404759 DOI: 10.1007/s00784-020-03728-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2020] [Accepted: 12/03/2020] [Indexed: 10/22/2022]
Abstract
OBJECTIVE To evaluate the performance of visual inspection alone and associated to radiographic and laser fluorescence (LF) methods in detecting non-evident caries lesions at adolescents' proximal surfaces. MATERIALS AND METHODS Adolescents (12 to 17 years old) were assessed for the presence of caries lesions through visual inspection, radiographic examination, and LF method (DIAGNOdent pen), at non-cavitated (NC) and cavitated lesion (CAV) thresholds. Temporary separation with orthodontic rubbers followed by direct visual inspection was the reference standard method. Two examiners conducted the examinations, and the first examiner reassessed around 20% of the sample, to evaluate inter- and intra-examiner reproducibility, respectively. Sensitivity, specificity, accuracy, and utility values were calculated for the methods alone and combined with visual inspection using two different strategies: simultaneous and sequential combination. RESULTS A total of 834 proximal surfaces (51 adolescents) were included. Visual inspection presented higher reproducibility values (higher than 0.98). Moreover, visual inspection presented higher sensitivity (around 0.51) than those obtained with other diagnostic strategies (varying from 0.09 to 0.20) at the NC threshold. For CAV, visual inspection presented higher specificity (0.996) than the sequential association with adjunct methods (around 0.97), but with lower sensitivity. Accuracy and utility values for combined strategies were similar or lower than those achieved with the visual inspection performed alone. CONCLUSION Visual inspection alone performs better for detecting caries lesions in premolars and molars of adolescents than other diagnostic strategies. CLINICAL RELEVANCE The best diagnostic strategy for caries detection of proximal caries lesions in adolescents is the visual inspection alone.

Abstract
BACKGROUND This study presents the correlation between laser speckle images and detection of incipient caries lesions from changs in the microstructure of the surface of tooth enamel. METHODS We used 30 healthy deciduous molar teeth collected from the Biobank Human Teeth, Faculty of Dentistry, University of São Paulo who had carious lesions induced by the pH cycling method. The samples were evaluated for the diagnosis of caries by two methods ICDAS and speckle pattern of coherent light scattering after 5, 10 and 15days and the results were statistically analyzed using α=0.05 significance level. RESULTS A significant difference was observed between the image of the speckle scattering of healthy and injured areas within the 3 study groups, but not when comparing the three groups, showing us that it is an innovative technique that needs further study, but can be used as a diagnostic method for the detection of early caries lesions. CONCLUSION It can be concluded that the analysis of scattering speckle pattern is a diagnostic technique that provides information on the microstructure of the surface of tooth enamel which has sensitivity for detection of incipient caries lesions.

Abstract
Following the consideration of several recent systematic and other reviews, there is a growing professional and scientific consensus that caries measurement methodology in caries clinical trials (CCT) should be updated to reflect progress made elsewhere in cariology. In this paper, therefore, “modern” means accepted in contemporary dental research and dental practice on the basis of sound research evidence—not necessarily new or requiring the use of new technology. Caries measurement should be seen in the context of the objectives of modern clinical caries management and the continuum of disease states, ranging from sub-surface carious changes through to more advanced lesions. Measurement concepts can be applied to at least three levels: the tooth surface, the individual, or the group/population. All are relevant to CCTs. Modern clinical caries management can be seen as comprised of seven discrete but linked steps (Steps 2, 3, and 4 are directly concerned with measurement.): (1) ‘Caries detection’ represents a yes/no decision as to whether caries is present; (2) lesion measurement assesses defined stages of the caries process, taking into account the histopatholgical morphology and appearance of different sizes and types of lesion and the diagnostic threshold(s) being used; (3) lesion monitoring by repeated measures at a series of examinations is used when lesions are less advanced than the stage judged to require operative intervention (A comparison of serial measurements permits the efficacy of preventive care aiming either to arrest or to reverse the lesion to be assessed.); (4) caries activity measures would be very valuable, but are relatively poorly developed and tested at present; (5) diagnosis, prognosis, and clinical decision-making are the important human processes in which all the information obtained from steps 1 to 4 is synthesised; (6) interventions/treatments, both preventive and operative, are now routinely used for caries management; and (7) outcome of caries control/management assesses caries management by examining evidence on the long-term outcomes. A challenge for the future is to define a range of optimal caries measurement methods—in use or in development in recent trials, in clinical practice, and/or in caries epidemiology—that will best contribute to more efficient, modern caries clinical trials.

Abstract
AIM The aim of this study was to compare and evaluate the efficacy of different diagnostic aids for diagnosis of dental caries and to compare the validity in terms of sensitivity and specificity of all four diagnostic modalities for diagnosis of caries. MATERIALS AND METHODS Occlusal surfaces of 100 primary and permanent molars were examined using the four diagnostic systems (visual, intraoral camera, DIAGNOdent, and DIAGNOdent with dye). These results were compared with operative intervention gold standard. Sensitivity and specificity were calculated for each diagnostic system for both enamel and dentin caries. Interrater agreement was calculated for each diagnostic system using kappa statistics. RESULTS For both enamel and dentin caries, the highest sensitivity values were provided by DIAGNOdent (0.91 and 0.72) and lowest for visual examination on wet surface (0.60 and 0.50). For both enamel and dentin caries, the specificity was found to be highest for intraoral camera on dry surface and lowest for visual examination. The DIAGNOdent gave the highest value of interrater agreement (kappa), i.e., 0.816 as compared with 0.03 for visual examination. CONCLUSION The study clearly demonstrated that DIAGNO-dent was the most accurate and valid system tested for the detection of occlusal caries. It has the advantage of quantifying the mineral content, helping to improve the diagnostic efficacy and treatment and accurate assessment of fissures where the visual examination alone is not adequate, thus complementing the traditional dental examination.

Abstract
The objective of the study was to evaluate the in vivo effectiveness of two fluorescence techniques (DIAGNOdent and VistaProof) and of visual and tactile evaluation in the diagnosis of occlusal caries in permanent teeth. A total of 302 teeth (molars and premolars) from 152 patients were studied. The occlusal surfaces were cleaned using pumice mixed with water, followed by application of the diagnostic methods according to the instructions of the manufacturer, and of the visual and tactile methods according to the recommendations. The true extent of the lesions was determined by fissurotomy. The sensitivity and specificity of visual diagnosis were 79 and 72 %, respectively, versus 53 and 98 % in the case of tactile diagnosis. Teeth with caries lesions exhibited significantly higher DIAGNOdent and VistaProof scores than those without caries. Using the optimum cutoff point of 23.5 obtained in our study for DIAGNOdent, sensitivity and specificity were found to be 92.4 and 92.7 %, respectively, while values of 88.1 and 95.1 % were obtained with a cutoff point of 28.5. Sensitivity in the case of the VistaProof system varied between 92.9 % (cutoff point 1.05) and 85.3 % (cutoff point 1.3), with respective specificity values of 95.8 and 88.6 %. The areas under the curve were 0.756, 0.759, 0.954 and 0.965 for the visual and tactile methods and for DIAGNOdent and VistaProof, respectively. The fluorescence-based techniques showed greater internal and external validity than the visual and tactile methods in diagnosing occlusal caries in permanent teeth. VistaProof is the best method for diagnosing caries in its early stages.

Abstract
Background/purpose Detection of approximal caries may be difficult using conventional methods including visual inspection (VI) and radiography. The purpose of this in vitro research was to evaluate the efficiency of light-emitting diode (LED) and laser fluorescence (LF) devices, and radiographic and visual examination in approximal caries diagnosis. Materials and methods One hundred and fifty-six approximal regions were evaluated. All approximal regions were investigated using LED and LF tools after radiography and VI were performed. Histological evaluation of teeth was performed using stereomicroscopy. The area under the receiver operating characteristic curve and accuracy, specificity, sensitivity values calculated regarding approximal caries diagnose. Results The specificity of the bitewing examination was higher for both T1 and T2 thresholds (0.97 and 0.99, respectively), and the LF device showed better sensitivity at each threshold compared with the other devices used for caries diagnosis (0.94 at T1 and 0.79 at T2). The receiver operating characteristic curves presented that the LF device was more successful than the other techniques at T1 threshold and VI was better than the other caries detection methods at T2 threshold. The kappa values for interobserver agreements were 0.43 (LF pen), 0.33 (LED device), 0.55 (VI), and 0.75 (bitewing examination). Conclusion The ability of bitewing radiography to identify sound surfaces was better than that of the other methods. The LF device was the most sensitive tool for detecting approximal surfaces with caries, followed by the LED device.

Abstract
Epidemiological data on dental caries show that prevention and treatment needs have evolved significantly over the past two decades. In younger patients the distribution of caries lesions is mainly found on the occlusal surfaces. The treatment approaches utilised by dentists must evolve to integrate preventive and treatment solutions tailored to the care needs, which are straightforward to implement in the dental office and whose effectiveness is underpinned by scientific evidence. This article aims to describe the principles of non-invasive management of non-cavitated (initial) occlusal caries lesions, based on evidence from recent studies published in the international literature.

Abstract
BACKGROUND No evidence about damage caused by ball-ended probes on tooth is available. No study compared probing defects caused by ball-ended probes with sharp explorers during tactile examinations of primary teeth. This exploratory study aimed to compare ultrastructural defects caused by ball-ended probes with sharp explorers during tactile examinations of primary teeth. METHODS Forty-nine primary extracted teeth were tactile examined as performed for caries activity assessment. Surfaces were randomly divided into groups based on probe type (ball-ended probe or sharp explorer). Two examiners probed different surfaces using the sharp explorer and the ball-ended probe. The order for examination was randomly determined. Images were captured using environmental scanning electron microscopy (ESEM) before and after probing. Two external examiners evaluated independently the ESEM images and scored them as: 0) no damage, 1) slight marks, 2) distinct marks, 3) marks with discontinuity, 4) enamel break-offs. Multilevel Poisson regression models were used to analyze associations between probing ultrastructural damage and surface type, baseline condition and probe type. Prevalence ratios (PR) were calculated with 95 % confidence interval (CI). RESULTS The most common defects observed on the dental surfaces were probing marks without discontinuity (scores 1 and 2). Ball-ended probes caused significantly less severe damage than sharp explorers (PR: 0.28; CI: 0.11-0.76, p = 0.01). CONCLUSION Ball-ended probes cause less damage than sharp explorers when probing gently dental surfaces of primary teeth.

Abstract
AIM To investigate the risk of sound surfaces, and initial and moderate caries lesions to progress to dentine cavitation in preschool children. DESIGN A cohort study was designed with 639 children (12-59 months old) who had been examined by visual inspection during a survey in 2010. After 2 years, 469 children were re-examined regarding the presence of dentine cavitations. The probability of progression was calculated for sound and carious (initial and moderate lesions) surfaces. Relative risk of progression and 95% confidence intervals for each condition compared with sound surfaces were calculated using multilevel Poisson regression analysis. Association with explanatory variables, including caries experience of the children, was also investigated. RESULTS The higher the initial score attributed to the dental surface, the more likely was the progression. Moreover, children with severe lesions at baseline had higher risk of having a sound surface or a non-cavitated caries lesion progressing to cavitation when compared with caries-free children; however, this increased risk was not observed in children with only initial caries lesions. CONCLUSIONS Initial caries lesions present a low frequency of progression. Moreover, sound surfaces and initial caries lesions in children already presenting cavitations are more likely to progress to more severe conditions.

Abstract
ABSTRACT Dental caries is a non-communicable disease and is considered a public health problem. For diagnosis and correct treatment, the study of risk assessment and caries activity is necessary. The caries risk assessment is a way to formalize the balance and imbalance of predictably disease to diagnose dental caries. Therefore, the caries risk assessment is performed through different evaluation systems. Another parameter of great importance to be studied is the activity of caries, because through it is done the correct treatment decision for the patient. The objective of this article is to inform the reader about: the concepts and caries risk factors; the different caries risk assessment systems described in the literature; and which systems are validated. In addition, this literature review provides for identification and evaluation of risk factors and activity of caries lesions in order to enable greater objectivity in the diagnosis and facilitate the decisions of a successful treatment.

Abstract
OBJECTIVES We aimed to assess the impact of the presence of initial and other stages of dental caries on the impairment of oral health-related quality of life in preschool children (COHRQoL) through a cohort study. METHODS During an epidemiological survey, 478 children (12-59 months old) were examined for dental caries using the International Caries and Detection Assessment System (ICDAS), and their parents answered the Early Childhood Oral Health Impact Scale (ECOHIS). Children were categorized based on the presence of dental caries as follows: children with no caries lesions, children with only initial lesions (ICDAS scores 1 and 2), children with at least one moderate lesion (ICDAS scores 3 and 4) and children with extensive lesions (ICDAS scores 5 and 6). After 2 years, 352 children were re-examined for the presence of dentine cavitations, and their parents completed a new ECOHIS questionnaire. Multilevel Poisson regression analysis was performed to evaluate the impact of the presence of different stages of caries lesions at the baseline on COHRQoL impairment at the follow-up, considering two outcome variables: worsening and severe worsening of COHRQoL. Relative risk values (RR) and respective 95% confidence intervals (95% CI) were calculated. RESULTS Worsening or severe worsening of the COHRQoL at the follow-up were observed only in children with moderate lesions (RR = 2.00; 95% CI = 1.30-3.08 and RR = 2.38; 95% CI = 1.31-4.34, respectively) or children with extensive lesions (RR = 1.59; 95% CI = 1.10-2.30 for worsening and RR = 1.88; 95% CI = 1.13-3.12 for severe worsening). On the other hand, the presence of only initial caries lesions was not a significant predictor of COHRQoL impairment. CONCLUSIONS The presence of only initial caries lesions does not impair COHRQoL of preschool children; however, moderate and extensive lesions are risk factors for worsening of the COHRQoL.

Abstract
BACKGROUND Secondary caries is the main reason for restoration replacement, and therefore, an accurate detection of this type of condition is fundamental. AIM To compare in vitro the performance of different conventional and quantitative light-induced fluorescence-based (QLF) methods in detecting occlusal caries around resin composite restorations in primary molars. DESIGN Two examiners evaluated independently 42 sites adjacent to tooth-colored restorations using visual inspection (ICDAS-CARS), radiographic examination, and QLF. Histological examination was used as reference standard method. Area under the ROC curve (Az), sensitivity, specificity, and accuracy of the methods were calculated at enamel (D1) and dentin caries (D3) lesions thresholds. Intra- and interexaminer reproducibility were calculated using intraclass correlation coefficient (ICC) and kappa statistics. RESULTS There was no difference among the methods considering Az at D1 threshold. Visual inspection, radiograph, and QLF (scores) methods presented similar sensitivities and significantly higher than those obtained with the QLF (∆F%). At D3 threshold, there were no differences among the methods regarding sensitivities, specificities, and accuracy, except for the examiner 2 with the QLF (∆F%) who achieved a very low sensitivity value. CONCLUSION Conventional methods are similar to QLF methods for detecting caries around tooth-colored restorations in primary teeth.

Abstract
The aim of this clinical study was to evaluate and compare the performance of visual exam with use of the Nyvad criteria (visual examination - (VE)), interproximal radiography (BW), laser fluorescence device (DIAGNOdent Pen-DDPen), and their association in the diagnosis of proximal lesions in primary teeth. For this purpose, 45 children (n = 59 surfaces) of both sexes, aged between 5 and 9 years were selected, who presented healthy primary molars or primary molars with signs suggestive of the presence of caries lesions. The surfaces were clinically evaluated and coded according to the Nyvad criteria and immediately afterwards with the DDPen. Radiographic exam was performed only on the surfaces coded with Nyvad scores 2, 3, 5, or 6. Active caries lesions and/or those with discontinuous surfaces were restored, considering the depth of lesion as reference standard. Sensitivity, specificity, accuracy, and area under ROC curve were calculated for each technique and its associations. Visual exam with Nyvad criteria presented the highest specificity, accuracy, and area under ROC curve values. The DDPen presented the highest sensitivity values. Association with one or more methods resulted in an increase in specificity. The performance of visual, radiographic, and DDpen exams and their associations were good; however, the clinical examination with the Nyvad criteria was sufficient for the diagnosis of interproximal lesions in primary teeth.

Abstract
OBJECTIVE The purpose of this study was to assess whether the diode laser (DL) pulpotomy method is a suitable alternative to formocresol (FC) and ferric sulphate (FS) pulpotomies in human primary teeth. BACKGROUND DATA Pulpotomy is the amputation of infected coronal pulp to maintain radicular pulp vitality and function. Although FC is regarded as the gold standard for pulpotomy in primary teeth, concerns about its safety have been reported. Lasers are an effective nonpharmacological alternative for treating pulp in children. METHODS This study included 120 primary molars in 58 children 5-9 years of age who underwent an identical conventional pulpotomy technique; the molars were allocated to FC, FS, and DL groups. After removal of the coronal tissue, complete hemostasis of the remaining pulp in the DL group was achieved by DL at 1.5 W, 30 Hz, and 50 mJ, with a 10 sec exposure time. For the FC group, diluted FC (1:5 Buckley's formocresol) was used for 5 min., and for the FS group, a 15.5% FS solution was used for 15 sec. Treatments in all groups were completed with stainless steel crowns and monitored clinically and radiographically at 1, 3, 6, 9, and 12 months. RESULTS The clinical success rates at 12 months were 97%, 95%, and 100%, whereas the radiographic success rates were 87%, 79%, and 75%, for the FC, FS and DL groups, respectively. The differences in the results were not statistically significant according to the χ(2) test (p>0.05). CONCLUSIONS DL pulpotomy offers a high clinical success rate, however considering radiographic success rate, it may not replace traditional FC and FS pulpotomies in primary molars.

Abstract
Preservation of natural tooth structure requires early detection of the carious lesion and is associated with comprehensive patient dental care. Processes aiming to detect carious lesions in the initial stage with optimum efficiency employ a variety of technologies such as magnifying loupes, transillumination, light and laser fluorescence (QLF® and DIAGNOdent® ) and autofluorescence (Soprolife® and VistaCam®), electric current/impedance (CarieScan(®) ), tomographic imaging and image processing. Most fluorescent caries detection tools can discriminate between healthy and carious dental tissue, demonstrating different levels of sensitivity and specificity. Based on the fluorescence principle, an LED camera (Soprolife® ) was developed (Sopro-Acteon, La Ciotat, France) which combined magnification, fluorescence, picture acquisition and an innovative therapeutic concept called light-induced fluorescence evaluator for diagnosis and treatment (LIFEDT). This article is rounded off by a Soprolife® illustration about minimally or even non-invasive dental techniques, distinguishing those that preserve or reinforce the enamel and enamel-dentine structures without any preparation (MIT1- minimally invasive therapy 1) from those that require minimum preparation of the dental tissues (MIT2 - minimally invasive therapy 2) using several clinical cases as examples. MIT1 encompasses all the dental techniques aimed at disinfection, remineralizing, reversing and sealing the caries process and MIT2 involves a series of specific tools, including microburs, air abrasion devices, sonic and ultrasonic inserts and photo-activated disinfection to achieve minimal preparation of the tooth. With respect to minimally invasive treatment and prevention, the use of lasers is discussed. Furthermore, while most practices operate under a surgical model, Caries Management by Risk Assessment (CaMBRA) encourages a medical model of disease prevention and management to control the manifestation of the disease, or keep the oral environment in a state of balance between pathological and preventive factors. Early detection and diagnosis and prediction of lesion activity are of great interest and may change traditional operative procedures substantially. Fluorescence tools with high levels of magnification and observational capacity should guide clinicians towards a more preventive and minimally invasive treatment strategy.

Abstract
BACKGROUND Fluorescence-based methods have been proposed to aid caries lesion detection. Summarizing and analysing findings of studies about fluorescence-based methods could clarify their real benefits. OBJECTIVE We aimed to perform a comprehensive systematic review and meta-analysis to evaluate the accuracy of fluorescence-based methods in detecting caries lesions. DATA SOURCE Two independent reviewers searched PubMed, Embase and Scopus through June 2012 to identify papers/articles published. Other sources were checked to identify non-published literature. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND DIAGNOSTIC METHODS: The eligibility criteria were studies that: (1) have assessed the accuracy of fluorescence-based methods of detecting caries lesions on occlusal, approximal or smooth surfaces, in both primary or permanent human teeth, in the laboratory or clinical setting; (2) have used a reference standard; and (3) have reported sufficient data relating to the sample size and the accuracy of methods. STUDY APPRAISAL AND SYNTHESIS METHODS A diagnostic 2×2 table was extracted from included studies to calculate the pooled sensitivity, specificity and overall accuracy parameters (Diagnostic Odds Ratio and Summary Receiver-Operating curve). The analyses were performed separately for each method and different characteristics of the studies. The quality of the studies and heterogeneity were also evaluated. RESULTS Seventy five studies met the inclusion criteria from the 434 articles initially identified. The search of the grey or non-published literature did not identify any further studies. In general, the analysis demonstrated that the fluorescence-based method tend to have similar accuracy for all types of teeth, dental surfaces or settings. There was a trend of better performance of fluorescence methods in detecting more advanced caries lesions. We also observed moderate to high heterogeneity and evidenced publication bias. CONCLUSIONS Fluorescence-based devices have similar overall performance; however, better accuracy in detecting more advanced caries lesions has been observed.

Abstract
AIM This in vitro study aimed to test the performance of fluorescence-based methods in detecting occlusal caries lesions in primary molars compared to conventional methods. DESIGN Two examiners assessed 113 sites on 77 occlusal surfaces of primary molars using three fluorescence devices: DIAGNOdent (LF), DIAGNOdent pen (LFpen), and fluorescence camera (VistaProof-FC). Visual inspection (ICDAS) and radiographic methods were also evaluated. One examiner repeated the evaluations after one month. As reference standard method, the lesion depth was determined after sectioning and evaluation in stereomicroscope. The area under the ROC curve (Az), sensitivity, specificity, and accuracy of the methods were calculated at enamel (D1) and dentine caries (D3) lesions thresholds. The intra and interexaminer reproducibility were calculated using the intraclass correlation coefficient (ICC) and kappa statistics. RESULTS At D1, visual inspection presented higher sensitivities (0.97-0.99) but lower specificities (0.18-0.25). At D3, all the methods demonstrated similar performance (Az values around 0.90). Visual and radiographic methods showed a slightly higher specificity (values higher than 0.96) than the fluorescence based ones (values around 0.88). In general, all methods presented high reproducibility (ICC higher than 0.79). CONCLUSIONS 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.

Abstract
OBJECTIVE To assess the variability in diagnosis and treatment of occlusal caries among dental practitioners in Kuwait using the International Caries Detection and Assessment System (ICDAS) criteria. METHODS A representative random sample of 156 dentists were interviewed. After completing a survey that included information about their gender, age, years in practice, place of practice, place of dental education, and specialty, practitioners examined four separately mounted molars (I-IV) for probable occlusal caries according to the ICDAS-II visual criteria. They were then asked to answer a set of questions related to their diagnosis and treatment of each tooth. The teeth were then histologically sectioned, and two independent investigators evaluated the depth of the caries according to Hintze and Wenzel's histologic criteria. RESULTS According to the histologic examination, tooth I and III had caries into enamel, while tooth II and IV had caries into dentin. About 50% of the participants diagnosed teeth with enamel caries as sound. About 60% of the participants correctly diagnosed teeth with caries extending into dentin. A restorative treatment modality was recommended for enamel caries by approximately 50% of the participants and for dentin caries by more than 80% of the participants. Dentists with a specialty in restorative dentistry had a tendency to underdiagnose enamel caries, while general practitioners and other specialists tended to overtreat enamel caries. CONCLUSIONS There was an evident variability in the diagnosis and treatment choices of occlusal caries among dentists working in Kuwait. Among the factors studied, the specialty of the participants was the only factor that had an effect on the participants' diagnosis and treatment of occlusal caries.

Abstract
OBJECTIVE Early dental caries diagnosis within the changing global pattern of dental caries development requires the use of auxiliary resources and adjuncts to diagnosis. The aim of this study was to introduce an alternative resource for drying teeth to enable early diagnosis of dental caries in epidemiological surveys. METHODS Polyurethane tips and three-in-one syringes were fitted to nebulizers and non-professional portable compressors for dental surface drying. The output air pressure of these sets was compared with the output pressure from the three-in-one syringe in a dental office. RESULTS Although the output pressure from the alternative resources was lower than the output pressure from the dental office equipment, the dental surfaces were dried satisfactorily, allowing the early diagnosis of the dental caries. CONCLUSION When a dental setting is not available, these alternative resources for drying teeth can be used satisfactorily.

Abstract
AIM Australian pre-school children living in rural areas experience higher levels of dental caries than those in metropolitan areas. This may be because of a lack of community water fluoridation. The aim of this study was to evaluate the effectiveness of a community-based intervention to improve the oral health of children in non-fluoridated rural Victoria, Australia. METHODS The study was conducted across three local government areas in Victoria, with two receiving the intervention and one remaining with standard care. Although multifaceted, the primary strategy of the intervention was the promotion of early exposure to fluoridated toothpaste, including the distribution, by maternal and child health nurses (MCHNs), of an oral health starter kit including toothpaste, toothbrush and information to parents at their child's 7-8-month health check. Children were followed up annually to the age of three. RESULTS Infants in the intervention arm experienced less caries (cavitated and pre-cavitated lesions included) than infants in the control arm at the first and second examinations (3.1% with caries in the intervention vs. 6.9% in the control group at exam 1 (adjusted P= 0.07) and 10.8% vs. 19.5% at exam 2 (adjusted P= 0.11), respectively). However potential benefits disappeared at the third examination (29.5% vs. 28.9%, adjusted P= 0.67). CONCLUSIONS This study suggests that an oral health promotion intervention delivered via local MCHNs promoting early exposure to fluoride may be successful in reducing caries in the second year of life but less so in older children when participants have less contact with MCHNs.

Abstract
This article reviews the current methods for detection and assessment of caries lesions focusing on applicability for daily clinical practice. The end point is to arrive at a diagnosis for each caries lesion. Visual inspection aided by a ball-ended probe is essential for caries lesions assessment and the method must be used for all patients. Use of indices, for example, the International Caries Detection and Assessment System (ICDAS), can improve the performance of this method. Using visual inspection, the clinician must decide about the presence, severity and activity of lesions. After this process, additional methods could aid the dentist in reaching a more appropriate treatment decision in some cases. The ICDAS, including the activity assessment system or the Nyvad system, seems to be the best option to reach final diagnoses for managing lesions. The radiographic method is the most recommended additional method available for daily clinical practice.

Abstract
An in vivo study was conducted to verify the ability of laser fluorescence (LF) to assess the activity status of occlusal caries in primary teeth, using different air-drying times. Occlusal sites (707) were examined using LF (DIAGNOdent) after air-drying for 3 s and 15 s, and the difference between readings (DIF15 s-3 s) was calculated. For concurrent validation of LF, visual criteria-Nyvad (NY) and Lesion Activity Assessment associated with the International Caries Detection and Assessment System (LAA-ICDAS)-were the reference standards for lesion activity. Histological exam using a pH-indicator dye (0.1% methyl red) was performed in 46 exfoliated/extracted teeth for criterion validation. LF readings and DIF15 s-3 s were compared using Kruskall-Wallis and Mann-Whitney tests. Receiver operating characteristic analyses were performed and validity parameters calculated, considering the caries activity assessment. Using NY, active lesions (3 s: 30.0+/-29.3; 15 s: 34.2+/-30.6) presented higher LF readings than inactive lesions (3 s: 17.0+/-16.3; 15 s: 19.2+/-17.3; p<0.05), different from LAA-ICDAS. Active cavitated caries resulted in higher LF readings (3 s: 50.3+/-3.5; 15 s: 54.7+/-30.2) than inactive cavitated caries (3 s: 19.9+/-16.3; 15 s: 22.8+/-16.8). Therefore, LF can distinguish cavitated active and inactive lesions classified by NY, but not by LAA-ICDAS; however, this difference might be related to the visual system rather than to LF. The air-drying time could be an alternative to improve the caries activity assessment; however, longer air-drying time is suggested to be tested subsequently.

Abstract
The aim of this study was to assess the frequency of routine use of dental prophylaxis prior to visual inspection, in order to diagnose caries, by dentists with different lapses of time after graduating time. One hundred and fifty one Brazilian dentists were interviewed in 3 Brazilian cities to determine if they usually remove dental plaque prior to visual inspection for caries diagnosis. The dentists were stratified according to year of graduation. The association between the lapse of time after graduating and the practice of routinely removing dental plaque before clinical examination was tested using the chi-square test with a significance level of 5%. Only 28.5% of the dentists reported that they usually remove dental plaque prior to clinical examination. The dentists who graduated in the last 15 years presented the lowest percentages of plaque removal prior to clinical examination (15.1%), whereas the more experienced dentists reported that they perform prophylaxis more frequently. Of the professionals who graduated from 1960-1975, 23.9% reported that they performed dental plaque removal prior to diagnosis, whereas the figure for those graduating from 1976-1990 was 46.2%. Most of the dentists interviewed reported that they did not remove dental plaque prior to performing visual diagnosis of caries.

Abstract
Realization that dental caries is a reversible, dynamic biochemical event at a micron level has changed the way the profession recognizes the caries disease and the caries lesion. The diagnosis of dental caries poses challenges due to the complex interaction of multiple endogenous causal factors. The most appropriate diagnostic aid for this purpose is the risk model of caries risk assessment. The analyses of the biological determinants provide clues to the dominant causal factor. The detection of a carious lesion has undergone a rigorous revision and revolution in order to identify the earliest mineral change so that it can be controlled without resorting to invasive management options. Apart from detection, it became mandatory to assess the extent of the lesion (noncavitated/cavitated), assess the activity status of the lesion (active/arrested), monitor the lesion progress (progression/regression over a period of time), and finally to predict the prognosis of the lesion as well as the disease. The prognosis of the disease can be best assessed by analyzing the predictor factors in caries risk assessment. The ultimate objective of such a meticulous and methodical approach aids in devising a tailor-made treatment plan, using preventing measures precisely and restorative measures minimally. This ensures the best oral health outcome of the patient.

Abstract
O presente estudo teve como objetivo analisar a incidência da cárie dentária em adolescentes associada à condição sócio-econômica, acesso a serviços e autopercepção. É um estudo longitudinal por meio de levantamento epidemiológico de cárie e questionário estruturado com amostra composta por 688 adolescentes residentes no Município de Sobral, Ceará, Brasil. A incidência aumentou progressivamente com a idade, passando de 1,60 nos adolescentes com 12 anos até 2,28 para os com 15 anos, registrando-se uma incidência média de 1,86 dentes cariados por adolescente. Entre as variáveis estudadas, dor de dente nos últimos seis meses [RR = 1,46 (1,22-1,76)], merenda escolar [RR = 1,45 (1,21-1,74)], freqüência de consulta ao dentista [RR = 1,48 (1,33-1,79)] e acesso à unidade de saúde [RR = 1,21 (1,01-1,45)], ajustadas por morbidade referida apresentaram relação com a alta incidência de cárie. É fundamental que gestores e profissionais de saúde formulem políticas públicas que não se restrinjam a aspectos como atendimento clínico e prevenção de doenças, estimulando a população na luta pela conquista por melhores condições de vida, viabilizando eqüidade no acesso aos serviços e desenvolvendo uma gestão coletiva das ações de saúde.

Abstract
The aims were to determine caries prevalence in 9-year-olds belonging to a low-caries prevalence population and to assess how accurately some commonly used risk factors/risk markers (predictors) can identify additional approximal caries as judged from bitewing examination (BW). One calibrated dentist examined 117 consecutive 9-year-olds from the inner city of Stockholm. The predictors were the number of clinically detected dfs and DFS, visible plaque, salivary mutans streptococci, tooth brushing habits, consumption of sugary products, parents' education, and (before BW) an overall clinical judgement by the examiner. Analyses of the data included sensitivity and specificity and a multiple logistic regression model. When BW was included, the mean DFS was 0.27 and the mean dfs 1.74. For approximal enamel and dentin lesions, the average gain from BW was 0.20 lesions for permanent first molars and 1.23 lesions for primary molars. Altogether, 48% of the children benefited from BW. The best predictors of additional approximal caries from BW were presence of caries (cavitation/dentin level) on occlusal surfaces of permanent first molars and the dentist's judgement based on clinical findings, both with a combined sensitivity and specificity of 134%. The only statistically significant variables in a logistic regression model were the dentist's judgement and the child's statement about regular tooth brushing. It is concluded that a sizeable proportion of 9-year-olds, representing a low-caries prevalence population, benefited from BW. However, the ability to identify these children from the predictors was limited.

Abstract
The aim of this study was to test whether the status of the adjacent tooth surface has an influence on the signal of a new laser fluorescence (LF) device for the detection of approximal caries. Seventy-eight teeth were selected from a pool of extracted permanent human molars, frozen at -20 degrees C until use. Before being measured the teeth were defrosted, cleaned, and any calculus removed. As a control, a defined approximal surface of each tooth was measured with the LF device holding the tip with the detecting- and the reverse-side on it, but without a neighboring tooth contacting the surface. The proximal site under examination was then placed adjacent to a tooth, which had deep dentinal caries, a composite restoration, a provisional ZnO-Eugenol restoration, or a ceramic restoration. The adjacent tooth with the ZnO-Eugenol restoration, the composite restoration, and the dentinal caries all demonstrated a statistically significant increase of LF readings on sound tooth surfaces. Teeth with enamel or dentinal caries were only slightly (and not statistically significantly) influenced by the different types of neighboring surfaces compared with the control LF readings. It can be concluded that caries detection of approximal tooth surfaces with the new LF system might be influenced by the condition of the adjacent tooth surface.

Abstract
In this article, the fundamentals of caries diagnosis are reviewed from the three component perspectives, namely the strategy, the logics, and the tactics. Strategy concerns the objectives of the diagnostic process (i.e. why we diagnose caries). The logics describe how we assemble and evaluate the information collected and how this leads to an assessment of diagnostic value. Finally, tactics are about how we collect the information necessary to arrive at a correct diagnosis. We argue that the hitherto-dominant essentialistic caries paradigm should be replaced by a nominalistic caries concept. This allows us to circumvent the problem of a lack of a caries gold standard and to proceed in caries-diagnostic research to find the diagnostic methods that result in the best health outcomes for our patients. We also demonstrate the limitations of the medical model when attempting to understand caries diagnosis, and adhere to the Bader & Shugars caries script model. It is concluded that the current caries profile, characterized by lower prevalence and extent, and slower progression, has increased the need for an academic strengthening of the dental curriculum with respect to diagnostic reasoning and clinical decision-making processes.

Abstract
A laser fluorescence (LF) device is a portable tool, but it does not measure minor mineral changes. Our in vitro study aim is to propose the association of an LF with two fluorescent dyes and to evaluate the performance in detecting and quantifying early demineralization. Artificial caries lesions are created in 40 primary canine teeth using a demineralizing solution (pH=4.8) for 12, 24, 48, and 96 h. LF measurements are performed with DIAGNOdent after demineralization in these samples and in 20 sound primary teeth. Measurements with LF with 0.2-mM tetrakis(N-methylpyridyl)porphyrin (LF TMPyP) and with 4-mM protoporphyrin IX (LF PPIX) are made. The amount of calcium loss is determined by atomic emission spectrometry. A correlation between LF and LF with dyes and mineral loss and receiver operating characteristics analysis are performed, as well as comparisons of sensitivity, specificity, and accuracy values. Significant correlation is obtained with LF TMPyP and mineral loss of lesions demineralized for 24, 48, and 96 h. Better performance is achieved with LF TMPyP for all parameters than with LF alone. LF PPIX does not present good results. In conclusion, LF TMPyP provides good performance in detecting and quantifying very early enamel caries lesions.

Abstract
The laser device DIAGNOdent developed for the detection of occlusal caries has limited value on approximal surfaces. The aim of this study was to develop and to test a new laser fluorescence (LF) device for the detection of approximal caries. Light with a wavelength of 655 nm was transported to the approximal surface using two different sapphire fibre tips. Seventy-five teeth were selected from a pool of extracted permanent human molars, frozen at -20 degrees C until use. Before being measured, they were defrosted, cleaned and calculus was removed with a scaler. The molars were set in blocks simulating the contact area of adults. Bitewing radiographs were obtained using Kodak Insight films. After two independent assessments with the new LF device, the teeth were histologically prepared, and assessed for caries extension. Using the laser, specificity values for D1 threshold (outer half of enamel), D2 threshold (inner half of enamel), D3 threshold (dentine) ranged between 0.81 and 0.93, sensitivity between 0.84 and 0.92 with no difference between the two tips. Bitewing radiography showed an inferior performance compared to LF (p<0.05). Intraex aminer reproducibility was high (kappa>.74). The new LF system might be a useful additional tool in detecting approximal caries. Because of its good reproducibility, it could be used to monitor caries regression or progression on approximal surfaces.

Abstract
OBJECTIVES To compare performance of visual inspection and Laser fluorescence methods to detect occlusal caries lesions under clinical and laboratory conditions in permanent teeth. METHODS One hundred and ten sites in 57 third molars scheduled for extraction were examined with visual inspection and laser fluorescence (DIAGNOdent) device by two trained examiners. After the extraction, teeth were re-examined. Then, teeth were sectioned to perform histological validation. Best cut-off points were calculated with ROC analysis, and sensitivity, specificity and accuracy were calculated at D2 and D3 thresholds. Comparisons between the methods and conditions of examination were performed using McNemar test. Inter-examiner agreement in the same conditions and agreement between the methods performed in vivo and in vitro conditions were assessed by Kappa test. Laser fluorescence values obtained in two conditions were compared with Wilcoxon test. RESULTS No difference was observed with visual inspection in both conditions. Laser fluorescence performed in vitro presented higher specificity and accuracy at D3 threshold. Visual inspection showed higher reproducibility. After adjustment of cut-off points for laser fluorescence method, there was no difference between the evaluated parameters. CONCLUSION Only slightly differences were observed between the examinations performed under clinical and laboratory conditions in the detection of occlusal caries lesions in permanent teeth.

Abstract
BACKGROUND AND OBJECTIVES Previous studies have demonstrated that polarization sensitive optical coherence tomography (PS-OCT) can be used to image early dental caries. The purpose of this study was to compare the measured reflectivity of natural caries lesions found on smooth surfaces (interproximal lesions) with the mineral loss measured using digital microradiography (DM) in order to determine if PS-OCT can be used as a non-destructive method to measure the severity of dental decay and resolve the internal structure of caries lesions. MATERIALS AND METHODS A PS-OCT system operating at 1,310 nm was used to acquire polarization resolved images of natural white spot lesions and pigmented lesions on the smooth surfaces of extracted teeth. The integrated reflectivity from lesion areas was compared to polarized light microscopic images (PLM) and to the integrated mineral loss from the same lesion area measured using high resolution DM. RESULTS The frequently complex internal structure of caries lesions could be resolved with PS-OCT. Such structural information is potentially useful for determining whether or not the lesion is active and progressing or whether it has become arrested and remineralized and does not require intervention. There was a strong correlation between the integrated mineral loss of the caries lesions measured using DM and the integrated reflectivity in the perpendicular polarization axis of the PS-OCT system. CONCLUSIONS The integrated reflectivity in the perpendicular polarization channel can be used to represent the severity of demineralization in natural early caries lesions. Therefore, PS-OCT has considerable potential as a non-destructive clinical probe of early caries lesions to assess their severity, monitor their progression over-time and potentially assess lesion activity.

Abstract
Traditionally, dentists have been trained in the surgical model for caries management whereby detection is akin to diagnosis. This model unfortunately has been translated to patient expectations. Nevertheless, a growing body of clinical evidence suggests that noncavitated lesions, even those extending into dentin, can be managed by nonsurgical means with an expectation for remineralization.
