Background: Detecting initial caries on the proximal surfaces of teeth in an intact dentition is a problem in dental practice since radiograph has been shown to have poor sensitivity with this stage of caries lesions. Hence there is need for an alternative technology. Objectives: The aim of this study was to investigate the efficacy of the Canary System (CS) to detect proximal caries in a clinical setting, comparing it with bitewing radiography (BWR).  Methodology: 33 subjects, age 18 years and above, were recruited from a mixed population of low, moderate, and high caries risk patients. BWR and the CS were used to detect proximal caries lesions in these subjects. Teeth were separated by 48 hours insertion of rubber rings, and the proximal surfaces were examined by direct visual examination using the International Caries Detection and Assessment System II (ICDAS-II) scoring system. The Sensitivity (se), specificity (sp), positive (ppv) and negative predictive (npv) values of the CS and BWR in detecting caries on proximal surfaces were calculated by evaluating each method alone against ICDAS-II system (used as bronze standard). The two methods were compared statistically using their Area Under the Receiver Operating Curve (AUC). The sensitivities and specificities were compared using a test of proportions and AUC values were compared using DeLong’s method of nonparametric testing of AUC values.  Results: The se, sp, ppv and npv for the CS are 0.92, 0.78, 0.89, 0.84 respectively, and for BWR are 0.67, 0.54, 0.78, and 0.40 respectively. The AUC of the Canary System (0.77) was statistically significantly higher than the AUC of the radiography (0.53, P < .001).  Conclusions: This study demonstrated the efficacy of the Canary System in detecting proximal caries lesions to be greater than that of bitewing radiography.  Clinical Significance: The Canary System can be a valuable clinical device for detecting and monitoring proximal caries lesions in clinical practice.

The use of fluoride, a healthy diet and good dental care habits are the pillars of the fight against caries. At a time when the anti-fluoride movement is on the increase and raises doubts even amongst the dentists and dental hygienists, the dental environment should be based on the credible scientific evidence regarding the effectiveness and safety of therapy in their clinical management. The article presents the clinical cases in which the agent for deep penetration fluoridation Tiefenfluorid® junior (Humanchemie, German) was used in the treatment and prevention of carious lesions in children. The visual-tactile method was used for detecting caries lesions. The International Caries Detection and Assessment System – ICDAS II was used for classifying dental caries. Carious lesions activity were assessed using visual-tactile method at control visits every 3 months within 12 months. Fluoride is effective in the treatment of initial caries in enamel, and the agent based on silver and fluorine SDF (Silver Diamine Fluoride) effectively inhibits tooth decay in the dentin. The disadvantage of SDF is the black color of the teeth. In contrast to common fluoride compounds, the solution with fluoride Tiefenfluorid® junior (Humanchemie, German) becomes non-toxic due to the reaction with the second application solution with calcium hydroxide. Furthermore, the process takes place deep in the funnels of the dental enamel, not on the tooth surface. The deep penetration fluoridation can be used for the caries prophylaxis, including the mineral fissure sealing, as well as for the treatment of initial caries lesions. In the treatment of initial caries in small children, it is an alternative to the silver nitrate impregnation and for the fluoride varnishes.

Objective: The aim of this study was to examine the impact of fluoride varnish and a new generation of nanoapatite varnish containing both Casein PhosphoPeptide − Amorphous Calcium Phosphate (CPP-ACP) and fluoride, on the activity of the initial smooth surface caries lesions of primary teeth. Materials and Methods: A randomized clinical trial was conducted on a total of 120 primary teeth with initial caries lesions in enamel, at children under the age of 24 months. Clinical evaluation of initial carious lesions and its evaluation during the research was carried out using the International Caries Detection and Assessment System (ICDAS-II). Results: There was a change of activity of the carious lesion in all three groups (CPP-ACPFG, FG and KG) during the time of treatment and follow-up, which was statistically significant. However, in the group of CPP-ACPFG, there was a better result compared to the FG and КG. Conclusion: Remineralizing treatment of new generation varnish containing both nanoapatite and fluоride gave a better result compared to conventional varnish with fluoride.

Background: There has been an increased incidence of dental caries in children due to recent changes in lifestyle. More sensitive and reproducible diagnostic tools for precise caries detection in children are needed because of the complex occlusal anatomy. Aim: To compare the clinical performance and accuracy of international caries detection and assessment system-II (ICDAS II) versus DIAGNOdent pen and digital bitewing radiograph in the detection of occlusal caries in the primary teeth. Materials and Methods: Fifty children aged 6-11 years were assessed of both gender (29 girls and 21 boys) and 377 occlusal surface of primary teeth were examined by visual ICDAS II, DIAGNOdent pen and digital bitewing radiographic examination at D0 (non caries lesions), D1 (lesions limited to enamel) and D2 (lesions limited to dentin) thresholds. Results: Sensitivity at D0 for ICADS II was 14.23% and 95.95% for DIAGNOdent pen and 87.85% for digital bitewing, radiographs while specificity for both ICADS II and bitewing radiographs were 99.23% but 73.85% for DIAGNOdent pen. At D1, threshold sensitivity of ICADS II and digital bitewing radiographs were higher than DIAGNOdent pen but specificity for bitewing radiographs and DIAGNOdent pen 90.69% - 87.99%. were highly significant than ICADS II At D2, threshold specificity for all diagnostic methods was almost similar with better sensitivity for ICADS II and digital bitewing radiographs. Conclusion: This study showed that ICDAS II, Diagnodent pen, and bitewing radiography are effective for the detection of occlusal caries for primary molars. Digital bitewing radiography correlated stronger with ICDASII than Diagnodent pen and proved to be the best method to detect occlusal lesions within the dentin in primary molars while Diagnodent pen and bitewing radiography are better for detecting enamel caries lesion. In addition, the clinical performance of three diagnostic methods was insufficient to detect occlusal caries lesions separately. Consequently, it is advisable to use a combination of diagnostic methods, especially in unclear cases, as well as in cases of initial lesions and their monitoring.

Introduction. The largest amount of information about the dental caries is provided by the International Caries Detection and Assessment II system (ICDAS II), which is known as evidence-based approach to clinical visual detection of dental caries and enables to detect the stage and depth of carious lesions from the slightest changes in dental enamel to visible cavities affecting dentin. This system has been developed by the group of leading experts in the field of cariology. The results obtained by determining the ICDAS II index contribute to making right clinical decision in the choice of prevention and treatment methods, as well as to predicting the carious progression. The aim of the study is to assess the prevalence and intensity of initial dental caries in people using the ICDAS II index. Materials and methods. A total of 32 patients aged 12 to 25 years were examined. During the dental examination, we assessed the prevalence of dental caries using the ICDAS II. Clinical findings were recorded in oral follow-up charts proposed by the ICDAS Foundation for Epidemiological Studies, which allow us to record dental hard tissue status using six codes: three for assessing carious changes in enamel and three for assessing carious changes in dentine in a sequence of growing severity. Statistical processing of the findings was performed using Student's t-test. Results. Carious lesions were detected in all study participants, their total number was 285, of which 140 (49.1%) had the code 1 and 145 (50.8%) had the code 2 according to the ICDAS II. On average, each of the participants had 9.28 ± 0.67 foci of enamel demineralization. The average number of lesions with codes 1 and 2 by the ICDAS II was respectively 4.54 ± 0.51 and 4.74 ± 0.38 (p> 0.05). The average intensity of dental caries increased with age from 8.29 ± 0.83 in 12-15 year old individuals to 9.39 ± 1.20 in 18-25 year old individuals (p> 0.05), mainly by the growth of the average number of the mean number of caries lesions with the code 1 according to the ICDAS II. Mostly carious lesions are found on the masticatory surfaces, their total number made up 159 (55.7%). 101 (35.4%) caries lesions were found on the vestibular and oral parts of the tooth surfaces, and 25 (8.9%) average lesions were detected on the proximal surfaces. The average intensity of caries detected on the chewing surfaces of the teeth was 5.15 ± 0.49 and was significantly higher than on the vestibular and oral (3.33 ± 0.57, p <0.05) and proximal (0.79 ± 0, 20, p <0.001) surfaces. Conclusion. The obtained results showed a high intensity of carious lesions, with their predominance in the active stages in the two age groups under the study. This proves the appropriateness of using diagnostic ICDAS criteria for early detection of initial caries and its proper treatment.

Background:Low viscosity resin infiltration of initial caries lesions is a modern microinvasive method to treat initial cries lesions. However, only scarce information is available about the long-term surface alterations of infiltrated lesions.Methods:Twenty-eight premolar teeth exhibiting non-cavitated initial caries lesions (International Caries Detection and Assessment System (ICDAS code 1&2)) were divided into two groups, one of which was infiltrated with resin, and the other remained untreated. The teeth underwent two thermocycling procedures. The surface roughness was determined quantitatively, and the results were evaluated statistically. In addition, the surfaces of the lesions were investigated by scanning electron microscopy (SEM), and the surface was analyzed visually with respect to surface irregularities.Results:The results showed a reduction in the surface roughness that was significant after 2500 thermocycles compared to the untreated surface. In the control specimens, no change in the surface roughness was found. The qualitative SEM data also showed a smooth surface after thermocycling, which supported the statistical findings.Conclusion:After thermocycling, resin-infiltrated enamel surfaces become smoother and had no additional risk for plaque accumulation.

ABSTRACT Aim The aim of this systematic review was to assess the in vivo scientific evidence regarding the ability of a recently developed light fluorescence device, SoproLife® (Sopro-Acteon group, La Ciotat, France) in detecting occlusal carious lesions. The PubMed database was searched for in vivo trials that evaluated the validity of the SoproLife® camera for the detection of occlusal carious lesions. Among the 11 articles originally identified with the keyword “Soprolife,” only three articles were included. The three included surveys used the International Caries Detection and Assessment System (ICDAS)-II criteria as gold standard for the assessment of SoproLife® compared or not to other detection devices (DIAGNOdent® and Spectra Caries Detection Aid®). Two of the included studies reported only on permanent teeth or both primary and permanent teeth. The SoproLife® validity values varied markedly among studies with a sensitivity ranging between 0.43 and 0.95 and a specificity between 0.55 and 1. Interobserver reproducibility with the SoproLife® was reported in two of the three studies (0.98 and 0.72) and none of the studies reported about intraobserver reproducibility. No clear-cut conclusion can be made based on the three included clinical studies; further in vivo investigations are needed to confirm the validity of the SoproLife® camera in terms of detection of occlusal carious lesions.

Caries lesions develop when acid production from bacterial metabolism of dietary carbohydrates outweighs the various mechanisms that promote pH homeostasis, including bacterial alkali production. Therapies that provide arginine as a substrate for alkali production in supragingival oral biofilms have strong anticaries potential. The objective of this study was to investigate the metabolic profile of site-specific supragingival plaque in response to the use of arginine (Arg: 1.5% arginine, fluoride-free) or fluoride (F: 1,100 ppm F/NaF) toothpastes. Eighty-three adults of different caries status were recruited and assigned to treatment with Arg or F for 12 wk. Caries lesions were diagnosed using International Caries Detection and Assessment System II, and plaque samples were collected from caries-free and carious tooth surfaces. Taxonomic profiles were obtained by HOMINGS (Human Oral Microbe Identification using Next Generation Sequencing), and plaque metabolism was assessed by the levels of arginine catabolism via the arginine deiminase pathway (ADS), acidogenicity, and global metabolomics. Principal component analysis (PCA), partial least squares–discriminant analysis, analysis of variance, and random forest tests were used to distinguish metabolic profiles. Of the 509 active lesions diagnosed at baseline, 70 (14%) were inactive after 12 wk. Generalized linear model showed that enamel lesions were significantly more likely to become inactive compared to dentin lesions ( P < 0.0001), but no difference was found when treatment with Arg was compared to F ( P = 0.46). Arg significantly increased plaque ADS activity ( P = 0.031) and plaque pH values after incubation with glucose ( P = 0.001). F reduced plaque lactate production from endogenous sources ( P = 0.02). PCA revealed differences between the metabolic profiles of plaque treated with Arg or F. Arg significantly affected the concentrations of 16 metabolites, including phenethylamine, agmatine, and glucosamine-6-phosphate ( P < 0.05), while F affected the concentrations of 9 metabolites, including phenethylamine, N-methyl-glutamate, and agmatine ( P < 0.05). The anticaries mechanisms of action of arginine and fluoride are distinct. Arginine metabolism promotes biofilm pH homeostasis, whereas fluoride is thought to enhance resistance of tooth minerals to low pH and reduce acid production by supragingival oral biofilms.

Although there is strong evidence for the effectiveness of sealants, one major barrier in sealant utilization is the concern of sealing over active caries lesions. This study evaluated detection and monitoring of caries lesions through a clear sealant over 44 mo. Sixty-four 7- to 10-year-old children with at least 2 permanent molars with International Caries Detection and Assessment System (ICDAS) scores 0-4 (and caries less than halfway through the dentin, radiographically) were examined with ICDAS, DIAGNOdent, and quantitative light-induced fluorescence (QLF) before sealant placement and 1, 12, 24, and 44 mo (except QLF) after. Bitewing radiographs were taken yearly. DIAGNOdent and QLF were able to distinguish between baseline ICDAS before and after sealant placement. There was no significant evidence of ICDAS progression at 12 mo, but there was small evidence of minor increases at 24 and 44 mo (14% and 14%, respectively) with only 2% ICDAS ≥ 5. Additionally, there was little evidence of radiographic progression (at 12 mo = 1%, 24 mo = 3%, and 44 mo = 9%). Sealant retention rates were excellent at 12 mo = 89%, 24 mo = 78%, and 44 mo = 70%. The small risk of sealant repair increased significantly as baseline ICDAS, DIAGNOdent, and QLF values increased. However, regardless of lesion severity, sealants were 100% effective at 12 mo and 98% effective over 44 mo in managing occlusal surfaces at ICDAS 0-4 ( i.e., only 4 of 228 teeth progressed to ICDAS ≥ 5 associated with sealants in need of repair and none to halfway or more through the dentin, radiographically). This study suggests that occlusal surfaces without frank cavitation (ICDAS 0-4) that are sealed with a clear sealant can be monitored with ICDAS, QLF, or DIAGNOdent, which may aid in predicting the need for sealant repair.

The aim of this study was to determine the caries status and risk factors in the schoolchildren of Spain’s Valencia region in 2018 and to compare them to the 20-year evolution of caries indicators in the region. A cross-sectional survey was conducted with 1722 children and adolescents aged between 6 and 15 using cluster sampling. Caries status, using International Caries Detection and Assessment System II (ICDAS II) criteria, and sociodemographic variables were recorded. To ensure the comparison with previous studies using WHO caries criteria, the cut-off point was established at ICDAS II code 4. Caries prevalence was found to be 37.4% and the decayed and filled teeth index (dft) was 1.23 at 6 years for deciduous dentition (DD). In permanent dentition (PD) at 12 years, caries prevalence was 30.1% with a 0.66 decayed, missing and filled teeth index (DMFT), and at 15 years, prevalence was 44.6% and DMFT was 1.21. Socioeconomic status poses a major risk factor for caries prevalence in deciduous dentition; it is 1.8 times higher in the lowest socioeconomic group. Deciduous dentition status has worsened in the most recent eight-year period, whereas in permanent dentition the 12- and 15-year values are similar to those of the 2010 survey. Evolution analysis suggests that community dental care programs be enhanced, involving preventive activities staring at the first year and targeting disadvantaged groups.
