RESUMO

INTRODUCTION: This consensus paper provides recommendations for oral health professionals on why and how to assess caries activity and progression with special respect to the site of a lesion. METHODS: An expert panel was nominated by the executive councils of the European Organization for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD). The steering committee built three working groups that were asked to provide recommendations on (1) caries detection and diagnostic methods, (2) caries activity and progression assessment, and (3) obtain individualized caries diagnoses. The experts of work group 2 phrased and agreed on provisional general and specific recommendations on caries lesion activity and progression, based on a review of the current literature. These recommendations were then discussed and refined in a consensus workshop followed by an anonymous Delphi survey to determine the agreement on each recommendation. RESULTS: The expert panel agreed on general (n = 7) and specific recommendations (n = 6). The specific recommendations cover coronal caries on pits and fissures, smooth surfaces, proximal surfaces, as well as root caries and secondary caries/caries adjacent to restorations and sealants. 3/13 recommendations yielded perfect agreement. CONCLUSION: The most suitable method for lesion activity assessment is the visual-tactile method. No single clinical characteristic is indicative of lesion activity; instead, lesion activity assessment is based on assessing and weighing several clinical signs. The recall intervals for visual and radiographic examination need to be adjusted to the presence of active caries lesions and recent caries progression rates. Modifications should be based on individual patient characteristics.

RESUMO

OBJECTIVES: The aim of the present consensus paper was to provide recommendations for clinical practice on the individual etiological and modifying factors to be assessed in the individual diagnosis of caries, and the methods for their assessment, supporting personalized treatment decisions. MATERIAL AND METHODS: The executive councils of the European Organisation for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD) nominated ten experts each to join the expert panel. The steering committee formed three work groups which were asked to provide recommendations on (1) caries detection and diagnostic methods, (2) caries activity assessment, and (3) forming individualized caries diagnoses. The experts responsible for "individualised caries diagnosis" searched and evaluated the relevant literature, drafted this manuscript and made provisional consensus recommendations. These recommendations were discussed and refined during the structured process in the whole work group. Finally, the agreement for each recommendation was determined using an anonymous eDelphi survey. The threshold for approval of recommendations was determined at 70% agreement. RESULTS: Ten recommendations were approved and agreed by the whole expert panel, covering medical history, caries experience, plaque, diet, fluoride, and saliva. While the level of evidence was low, the level of agreement was typically very high, except for one recommendation on salivary flow measurement, where 70% agreed. CONCLUSION: It is recommended that all aspects of caries lesion progression and activity, recent caries experience, medical conditions and medications, plaque, diet, fluoride and saliva should be synthesized to arrive at an individual diagnosis. CLINICAL RELEVANCE: The expert panel merged evidence from existing guidelines and scientific literature with practical considerations and provided recommendations for their use in daily dental practice.

RESUMO

OBJECTIVES: The aim of this prospective clinical study was to evaluate the impact of initial lip position on class II functional appliance therapy. MATERIALS AND METHODS: In total, 34 class II division 1 patients (23 females, 19 males; mean age 12.4 ± 0.9 years) that met the inclusion criteria (> ½ class II molar relationship, overjet > 6 mm, ANB > 4°, neutral or horizontal growth pattern, cervical vertebral maturation stage (CVMS) II - III, mean wear-time > 10 h/day) were consecutively divided into two groups (lip incompetence (LI); lip competence (LC)). All patients were treated with the Sander bite jumping appliance (BJA). Wear time was microelectronically measured. Lateral cephalograms were taken at the beginning (T0) and after 1 year of treatment (T1). An untreated class II group served as a control (CG). Inter-group comparisons were determined with Mann-Whitney U tests for independent samples. RESULTS: Significant skeletal treatment effects were found in both treated groups when compared to the CG with significantly more pronounced mandibular skeletal effects in the LI than in the LC group (mandibular base length p < 0.001, composite mandibular base length p < 0.001, condylar head growth p = 0.002, co-pg p < 0.00, go-pg p = 0.003, reduction of the ANB angle p = 0.009, and Wits appraisal p < 0.001). CONCLUSION: The more pronounced mandibular effects in the LI group were composed of the functional orthopedic effect plus harmonization of the lip competence. CLINICAL RELEVANCE: Functional harmonization of lip incompetence with BJA enhances mandibular growth stimulation. Lip incompetence seems to impede mandibular growth and its harmonization seems to be a preventive approach.

RESUMO

OBJECTIVES: The aim of the present consensus paper was to provide recommendations for clinical practice considering the use of visual examination, dental radiography and adjunct methods for primary caries detection. MATERIALS AND METHODS: The executive councils of the European Organisation for Caries Research (ORCA) and the European Federation of Conservative Dentistry (EFCD) nominated ten experts each to join the expert panel. The steering committee formed three work groups that were asked to provide recommendations on (1) caries detection and diagnostic methods, (2) caries activity assessment and (3) forming individualised caries diagnoses. The experts responsible for "caries detection and diagnostic methods" searched and evaluated the relevant literature, drafted this manuscript and made provisional consensus recommendations. These recommendations were discussed and refined during the structured process in the whole work group. Finally, the agreement for each recommendation was determined using an anonymous Delphi survey. RESULTS: Recommendations (N = 8) were approved and agreed upon by the whole expert panel: visual examination (N = 3), dental radiography (N = 3) and additional diagnostic methods (N = 2). While the quality of evidence was found to be heterogeneous, all recommendations were agreed upon by the expert panel. CONCLUSION: Visual examination is recommended as the first-choice method for the detection and assessment of caries lesions on accessible surfaces. Intraoral radiography, preferably bitewing, is recommended as an additional method. Adjunct, non-ionising radiation methods might also be useful in certain clinical situations. CLINICAL RELEVANCE: The expert panel merged evidence from the scientific literature with practical considerations and provided recommendations for their use in daily dental practice.

RESUMO

In order to optimize dental education, established procedures for caries diagnosis and therapy, such as the International Caries Classification and Management System (ICCMS), should be integrated into the curriculum. In preparation, the level of knowledge of dental students on caries detection and management was surveyed in order to specifically address deficits in dental teaching. In addition, the data were compared with the knowledge of clinically experienced dentists. The results are presented in this report and possible consequences for dental teaching are discussed.Twenty-six sixth semester dental students and six assistant dentists at the Department of Orthodontics (Philipps University of Marburg, Germany) were available for the written survey during the winter semester 2018/2019. For 12 anonymized orthodontic patient cases, the clinical findings, caries risk, and adequate treatment were to be determined for each defined tooth. The consensus decision of two experienced dentists served as the reference value. As a result, agreement with the reference ranged from 40.7% to 51.3% for students and from 56.9% to 75.0% for assistant dentists. The extent of caries and the resulting necessary treatment were mostly underestimated.In addition to theoretical knowledge, clinical experience is another prerequisite for adequate caries diagnosis and its management. The underestimation of caries extent and necessary treatment should be taken into account when teaching content. Procedures such as the ICCMS should be integrated into the dental curriculum at an early stage, so that orthodontic patients can also receive effective care.

RESUMO

During orthodontic treatment, enamel demineralization can occur. Its early detection is the basis for efficient preventive measures to arrest or remineralize lesions. In the present study, the application of a novel blue hemoglobin-based liquid (BlueCheck) was evaluated as proof of concept for detection of artificially demineralized smooth surfaces. 60 samples from extracted human posterior teeth were randomly assigned to four groups (15 per group). In 30 of these samples (groups A and B), superficial enamel was removed to create a ground surface. On the surface of other 30 samples (group C and D), orthodontic metal brackets were bonded. On each surface, BC liquid was applied and rinsed with water after 3 min (baseline). All surfaces were checked by two independent observers for presence of blue areas. On each sample, one side was covered by nail varnish to protect this enamel part from demineralization. The samples were demineralized with lactic acid (pH 4.6) for 7 days (group A and C) and 14 days (group B and D), respectively. Mineral loss was determined using quantitative light-induced fluorescence after demineralization. BlueCheck dye was again applied on the samples and evaluated for presence of stained areas. Histological sections were prepared from randomly selected samples and lesion depth was measured. Kruskal-Wallis test was used for group comparison (α = 0.05). After demineralization, median ΔF value for all samples was -8.25% indicating the presence of an initial demineralization. The difference of ΔF values was not statistically significant between samples at 7 or 14 days of demineralization, nor for samples with and without orthodontic brackets (p = 0.13). At baseline, none of the sample surfaces showed discoloration, whereas a distinctive blue color was visible after demineralization in all samples exposed to acid-exposed areas, corresponding to 100% sensitivity. The internal control surfaces (without demineralization) did not show any staining, corresponding to 100% specificity. Histologically measured lesion depths ranged between 200 and 254 µm. In this in vitro study, staining of demineralized enamel surface areas were shown to be reliable. Based on our results, this easily applicable product seems useful to be an adjuvant method to clinical examination to monitor oral health during an orthodontic treatment on tooth surfaces after removal of dental biofilm.

RESUMO

A 2-day workshop of ORCA and the IADR Cariology Research Group was organized to discuss and reach consensus on definitions of the most commonly used terms in cariology. The aims were to identify and to select the most commonly used terms of dental caries and dental caries management and to define them based on current concepts. Terms related to definition, diagnosis, risk assessment, and monitoring of dental caries were included. The Delphi process was used to establish terms to be considered using the nominal group method favored by consensus. Of 222 terms originally suggested by six cariologists from different countries, a total of 59 terms were reviewed after removing duplicates and unnecessary words. Sixteen experts in cariology took part in the process of reaching consensus about the definitions of the selected caries terms. Decisions were made following thorough "round table" discussions of each term and confirmed by secret electronic voting. Full agreement (100%) was reached on 17 terms, while the definitions of 6 terms were below the agreed 80% threshold of consensus. The suggested terminology is recommended for use in research, in public health, as well as in clinical practice.

RESUMO

This paper provides recommendations for dentists for the treatment of dental caries in children, with an emphasis on early childhood caries (ECC), primary teeth, and occlusal surfaces in permanent teeth. A consensus workshop followed by an e-Delphi consensus process was conducted with an expert panel nominated by the European Organization for Caries Research (ORCA) and European Federation of Conservative Dentistry (EFCD)/German Association of Conservative Dentistry (DGZ) boards. Based on 3 systematic reviews and a nonsystematic literature search, recommendations were developed. The caries decline has led to a more polarized disease distribution in children and adolescents along social gradients which should be taken into account when managing the caries process at all levels, such as the individual, the group, or a population. The control or reduction of caries activity is the basis for successful caries management. In children, caries management requires adequate daily oral hygiene and fluoride application via toothpaste, ensured by caregivers, and especially for ECC prevention an emphasis on sugar intake reduction is needed. These noninvasive interventions are also suitable to arrest or control initial or even cavitated dentine caries lesions in the absence of irreversible pulpitis. Fluoride varnish or silver diammine fluoride can be added as supplementary agents. In pits and fissures, composite resin materials can be used as preventive sealants and for defect-oriented minimally invasive restorations. In primary molars, preformed metal crowns are more successful than multisurface fillings, especially in caries-active patients. With persisting high caries activity, multiple lesions, and limited cooperation, caries control should consist of robust measures with high success rates, even including extraction in selected cases. This applies especially to treatments performed under general anesthesia.

RESUMO

AIM: To provide recommendations for dental clinicians for the management of dental caries in older adults with special emphasis on root caries lesions. METHODS: A consensus workshop followed by a Delphi consensus process were conducted with an expert panel nominated by ORCA, EFCD, and DGZ boards. Based on a systematic review of the literature, as well as non-systematic literature search, recommendations for clinicians were developed and consented in a two-stage Delphi process. RESULTS: Demographic and epidemiologic changes will significantly increase the need of management of older adults and root caries in the future. Ageing is associated with a decline of intrinsic capacities and an increased risk of general diseases. As oral and systemic health are linked, bidirectional consequences of diseases and interventions need to be considered. Caries prevention and treatment in older adults must respond to the patient's individual abilities for self-care and cooperation and often involves the support of caregivers. Systemic interventions may involve dietary counselling, oral hygiene instruction, the use of fluoridated toothpastes, and the stimulation of salivary flow. Local interventions to manage root lesions may comprise local biofilm control, application of highly fluoridated toothpastes or varnishes as well as antimicrobial agents. Restorative treatment is often compromised by the accessibility of such root caries lesions as well as the ability of the senior patient to cooperate. If optimum restorative treatment is impossible or inappropriate, long-term stabilization, e.g., by using glass-ionomer cements, and palliative treatments that aim to maintain oral function as long and as well as possible may be the treatment of choice for the individual.

RESUMO

OBJECTIVES: To provide consensus recommendations on how to intervene in the caries process in adults, specifically proximal and secondary carious lesions. METHODS: Based on two systematic reviews, a consensus conference and followed by an e-Delphi consensus process were held with EFCD/ORCA/DGZ delegates. RESULTS: Managing an individual's caries risk using non-invasive means (oral hygiene measures including flossing/interdental brushes, fluoride application) is recommended, as both proximal and secondary carious lesions may be prevented or their activity reduced. For proximal lesions, only cavitated lesions (confirmed by visual-tactile, or radiographically extending into the middle/inner dentine third) should be treated invasively/restoratively. Non-cavitated lesions may be successfully arrested using non-invasive measures in low-risk individuals or if radiographically confined to the enamel. In high-risk individuals or if radiographically extended into dentine, for these lesions, additional micro-invasive (lesion sealing and infiltration) treatment should be considered. For restoring proximal lesions, adhesive direct restorations allow minimally invasive, tooth-preserving preparations. Amalgams come with a lower risk of secondary lesions and may be preferable in more clinically complex scenarios, dependent on specific national guidelines. In structurally compromised (especially endodontically treated) teeth, indirect cuspal coverage restorations may be indicated. Detection methods for secondary lesions should be tailored according to the individual's caries risk. Avoiding false positive detection and over-treatment is a priority. Bitewing radiographs should be combined with visual-tactile assessment to confirm secondary caries detections. Review/refurbishing/resealing/repairing instead of replacing partially defective restorations should be considered for managing secondary caries, if possible. CONCLUSIONS: An individualized and lesion-specific approach is recommended for intervening in the caries process in adults. CLINICAL SIGNIFICANCE: Dental clinicians have an increasing number of interventions available for the management of dental caries. Many of them are grounded in the growing understanding of the disease. The best evidence, patients' expectations, clinicians' expertise, and the individual clinical scenario all need to be considered during the decision-making process.

RESUMO

Toothpastes are the most universally accepted form of fluoride delivery for caries prevention. To provide anti-caries benefits, they must be able to release fluoride during the time of tooth brushing or post brushing into the oral cavity. However, there is no standard accepted procedure to measure how much fluoride in a toothpaste may be (bio) available for release. The European Organization for Caries Research proposed and supported a workshop with experts in fluoride analysis in toothpastes and representatives from industry. The objective of the workshop was to discuss issues surrounding fluoride analysis in toothpaste and reach consensus on terminology and best practices, wherever the available evidence allowed it. Participants received a background paper and heard presentations followed by structured discussion to define the problem. The group also reviewed evidence on the validity, reliability and feasibility of each technique (namely chromatography and fluoride electroanalysis) and discussed their strengths and limitations. Participants were able to reach a consensus on terminology and were also able to identify and summarize the advantages and disadvantages of each technique. However, they agreed that most currently available methods were developed for regulatory agencies several decades ago, utilizing the best available data from clinical trials then, but require to be updated. They also agreed that although significant advances to our understanding of the mechanism of action of fluoride in toothpaste have been achieved over the past 4 decades, this clearly is an extraordinarily complex subject and more work remains to be done.

RESUMO

OBJECTIVES: Since early childhood caries (ECC) is a major disease in the public health sector, an interdisciplinary prevention concept to avert this disease was developed, launched in a project region, and evaluated. It was examined whether the emergence of ECC could be prevented or curbed with the newly developed program. MATERIALS AND METHODS: The program encompasses seven pulses of information from an interdisciplinary team (gynecologists, midwives, pediatricians, dentists, municipal social services, and the public health office). The primary dependent variables were caries experience and prevalence among the 3- to 4-year-olds who took part in the ECC prevention program, compared to children of the same age without such measures. The effect of the prevention program was assessed by means of a "historical" comparison. The dental diagnoses were performed by two calibrated dentists based on the "ICDAS collapsed." Data on diet and preventive behavior were gathered using a standardized parental questionnaire. The significance was tested using the nonparametric Mann-Whitney U test. RESULTS: There were 661 3- to 4-year-olds in the control group and 706 in the test group. The mean d3-6mf-t for the control group (0.92) was significantly higher than that for the test group (0.46). While 78.8% of the children examined in the control group exhibited predominantly sound primary dentition, this was the case for 86.3% of the test group. The proportion of children with S-ECC was 7.9% in the test group and 14.5% in the control group. The test group differed significantly from the control group both in terms of reported diet and dental hygiene habits. CONCLUSIONS AND CLINICAL RELEVANCE: The interdisciplinary prevention program presented here is an effective concept for preventing ECC and considerably helps reduce problems in the treatment of small children.

RESUMO

OBJECTIVES: The objective of the manuscript is to systematically review the different techniques developed for activity assessment of coronal carious lesions (AACCL) in clinical settings. MATERIALS AND METHODS: A search of PubMed identified original articles in English reporting on the different concepts/tools for AACCL in clinical settings and, when available, data related to their in vivo/in situ validation in terms of sensitivity, specificity, inter- and intra-examiner reproducibilities, area under the receiving operating curve, positive predictive value, negative predictive value, and relative risk of lesion progression. RESULTS: The present review included 25 articles. Four groups of techniques are available (1) systems based on combinations of visual and tactile criteria; devices based on (2) pH assessment, (3) fluorescence, or (4) bioluminescence. The most studied systems are those based on combinations of visual and tactile parameters when bioluminescence suffers from the lack of in vivo evaluation. Validation studies showed a wide disparity among protocols in terms of populations, dentitions, teeth surfaces, study design, the gold standard, and validation criteria. CONCLUSION: There is a need for definition and harmonization of standards for activity assessment-related concepts/tools, as well as further investigations for in vivo validation of newly developed tools. CLINICAL RELEVANCE: Carious lesion activity is an important component to be taken into account when making decisions as to appropriate clinical caries management. The development and use of validated techniques which are easy to use in everyday dental practice are important.

RESUMO

OBJECTIVE: Assessment of caries lesion activity is usually performed using visual-tactile criteria. A new approach is to use a system consisting of a photoprotein, which is specific for free calcium ions, along with an integrated camera that visualizes the elevated calcium ions on the lesion as a light signal (bioluminescence). This study aimed to evaluate the reproducibility and diagnostic accuracy of a newly developed bioluminescence system to assess caries lesion activity on occlusal surfaces in vitro. MATERIALS AND METHODS: Ninety-four extracted permanent teeth with sound surfaces and both active and inactive caries lesions were included. The extent and activity of the investigation sites were classified visually according to the International Caries Detection and Assessment System. Digital images of the teeth were produced by the bioluminescence system and the images were analyzed for the presence of caries activity (the bioluminescent areas at the investigation sites). The images were reanalyzed after 4 weeks. Teeth were hemisected and methyl red dye was applied on the sections to validate lesion activity histologically. RESULTS: Agreement between the bioluminescence readings was shown by κ values of 0.802-0.917. A significant positive correlation (p < 0.001) was found across all methods (rs 0.618-0.811). Sensitivity and specificity for activity assessment using histology as the gold standard (cut-off: active/inactive) were, respectively, 83.6 and 85.0% for the visual assessment, and 92.5 and 90.0% for the bioluminescence method. Comparison of areas under the receiver-operating characteristic curves showed no significant difference between the visual and bioluminescence systems (p = 0.094). CONCLUSION: The bioluminescence system demonstrated high in vitro reproducibility and good diagnostic accuracy for activity assessment of caries lesions on occlusal surfaces which were not significantly different from the values obtained in the visual assessment.

RESUMO

OBJECTIVES: Children in a German region took part in regular toothbrushing with fluoride gel during their time in primary school after having received a preventive program in kindergarten. The study aimed at determining the dental health of the students as a function of prevention in kindergarten and at school while taking into account their socioeconomic status and other confounders. MATERIALS AND METHODS: The subjects were in six groups: groups 1 and 2, intensive prevention in kindergarten with and without fluoride gel at school; groups 3 and 4, basic prevention in kindergarten with and without fluoride gel at school; groups 5 and 6, no organized prevention in kindergarten with and without fluoride gel at school. Two dental examinations were performed for assessing caries experience and calculating caries increment from second grade (7-year-olds) to fourth grade (9-year-olds). A standardized questionnaire was used to record independent variables. To compare caries scores and preventive measures of various subgroups, non-parametric tests and a binary logistic regression analysis were performed. RESULTS: A significant difference was found in the mean decayed, missing, and filled tooth/teeth (DMFT) depending on socioeconomic status (no prevention in kindergarten, fluoride gel at school in children with low SES: DMFT = 0.47 vs. DMFT = 0.18 in children with high SES; p = 0.023). Class-specific differences were no longer visible among children who had taken part in an intensive preventive program combining daily supervised toothbrushing in kindergarten and application of fluoride gel in school. CONCLUSIONS: Early prevention, focusing on professionally supported training of toothbrushing in kindergarten and at school, has a positive effect on dental health and is able to reduce class-specific differences in caries distribution. CLINICAL RELEVANCE: Early training of toothbrushing and fissure sealing of first permanent molars are the most important factors for the dental health of primary school children.

RESUMO

OBJECTIVES: In one region of Germany, a group of children took part in regular fluoride gel applications during primary school following intensified prevention in kindergarten. This observational study aimed to ascertain whether the dental health of primary school children can be improved by introducing a group prevention program based on applications of fluoride gel. MATERIALS AND METHODS: The subjects were distributed among six groups with varying preventive measures in kindergarten and at school. The basis for determining caries experience and calculating the caries increment consisted of dental findings gathered in the second and fourth grade. RESULTS: While second graders without professionally supported daily toothbrushing in kindergarten exhibited an average d3-6mft of 2.17, in those who had enjoyed intensive dental prevention, the corresponding value was 19% lower (d3-6mft = 1.74). The caries increment was significantly lower mainly among children who had received the maximum of group prevention (intensive prevention in kindergarten and gel program at school). CONCLUSIONS: The results show that intensified preventive programs in kindergartens and schools, based mainly on supervised toothbrushing, have a positive effect on the dental health of primary school children. CLINICAL RELEVANCE: Such programs are efficient in reducing caries experience especially in socially deprived areas.

RESUMO

OBJECTIVE: The objective of this study was to assess the ability of alternating current impedance spectroscopy technique (ACIST) to monitor sound tooth surfaces and incipient carious lesions. SUBJECTS AND METHODS: Two hundred ninety-two teeth were examined in 30 patients. Occlusal surfaces were classified according to International Caries Detection and Assessment System (ICDAS). Two consecutive ACIST measurements at the investigation sites already visually examined were taken (t1). Examinations were repeated after 6 (t2) and 12 months (t3). Reproducibility of ACIST findings was calculated with the intra-class correlation coefficient. Values of the ACIST measurements were categorized, and kappa values were calculated. Spearman correlation coefficients (r s) were calculated for correlations between ICDAS findings and ACIST measurements. To test whether ACIST detected changes similarly to ICDAS, Wilcoxon's test was used (α = 0.05). RESULTS: Intra-class correlation coefficient values of ACIST measurements ranged between 0.88 and 0.98. Kappa values for ACIST categories were 0.66-0.80. Rank correlation coefficient of ICDAS and ACIST readings was 0.38-0.65 at different time intervals (p < 0.01). Significant differences could be shown for ICDAS findings between t1/t2 (p = 0.001), t2/t3 (p = 0.021), and over the total duration of the study (t1/t3, p < 0.001). No significant differences between the various examination periods were found for the impedance measurements (p > 0.05). CONCLUSIONS: ACIST exhibited in vivo high reproducibility but moderate correlation to visual findings at each time of examination. CLINICAL RELEVANCE: ACIST can be used for monitoring sound teeth and early carious lesions although its suitability as a single detection method is limited since not all changes could be detected with respect to visual findings.

RESUMO

OBJECTIVES: The aim of the study was to evaluate the effect of an intensified preventive programme in kindergartens. MATERIALS AND METHODS: Two thousand two hundred twenty-eight 2- to 4-year-old children attending kindergartens in two counties in northern Hesse were randomly allocated to two groups. Children in the test group participated in daily tooth brushing with 500 ppm fluoride toothpaste, which was supervised by specially trained dental nurses. Children in the control group received tooth brushing instructions three to four times a year. Caries experience was recorded using WHO criteria. The basic survey was performed from October 2006 to April 2007, with the final examinations between March and July 2009. The statistical evaluation was performed by means of the software package SPSS 17.0. To compare the mean Δdmf values of the test and control groups, Mann-Whitney U tests were performed. RESULTS: Two thousand one hundred twelve children (test group, 1096; control group, 1048) participated in the final examinations. The caries increment of the test group (Δdmf-s = 1.55) was 24 % lower than the increment of the control group (Δdmf-s = 2.02, p = 0.043). Based on Δdmf-t values, the corresponding figures were 0.79 for the test group and 1 for the control group (p = 0.44). High increment values (Δdmf-s >7) were observed in the control group twice as often as in the test group. CONCLUSION: The results show that an intensified preventive programme in kindergartens, based on supervised daily tooth brushing, has a positive effect on the dental health of preschool children. CLINICAL RELEVANCE: It is sufficient to offer such programmes in socially deprived areas.

RESUMO

BACKGROUND: Sound teeth and incipient lesions require regular monitoring to detect possible progression of caries early on. AIM: To evaluate the ability of the VistaProof (VP) fluorescence-based camera for monitoring occlusal surfaces. DESIGN: A total of 419 posterior teeth (205 primary molars, 145 permanent molars, and 69 premolars) of 35 patients were examined (average age: 9.1 years). The occlusal surfaces were classified visually according to the criteria of the International Caries Detection and Assessment System (ICDAS). VP measurements were performed at baseline (t1), and the examinations were repeated after six (t2) and twelve month (t3). Correlation between methods was calculated using Spearman's rank correlation coefficient (rs ). Wilcoxon test was used to monitor whether VP identified changes as well as ICDAS (α = 0.05). RESULTS: Correlations between ICDAS and VP were significantly positive (rs : 0.66-0.73, P < 0.001). No significant differences were found between all times for the ICDAS findings. Significant differences for the VP were ascertained for t1/t2 (P = 0.03). Results based on cluster randomization showed significant differences between ICDAS and VistaProof concerning the absence/presence of changes in the finding (P < 0.0005). CONCLUSION: Correlation between ICDAS and VP was strong. The VP supported the findings of visual examination for monitoring occlusal surfaces, although not all changes could be detected with respect to the visual findings.

RESUMO

The aim of this study was to assess the performance of the fluorescence camera device VistaCam iX (VC) for the control of caries excavation compared to visual assessment and bacteriological evaluation. Twenty-three patients with 32 dentinal carious lesions were included in the study. The lesions were classified using the International Caries Detection and Assessment System. Fluorescence images were taken at the surface of each lesion using the VC before excavation (stage 1), during (stage 2) and after excavation (stage 3). At each stage, dentine samples were collected. All cavities were closed after excavation using permanent fillings. Bacteria were counted within each dentine sample using flow cytometry. Significant moderate correlation between the fluorescence readings and the bacteria count was found at stage 3 (Spearman correlation coefficient rs = 0.40, p = 0.027). Area under the ROC curve (AUC) was calculated for fluorescence readings and bacteria count using the clinical status at stage 3 as a reference. AUC was 0.954 for the VC readings and 0.797 for bacteria count. Using the median bacteria count at stage 3 as a reference, the AUC for the fluorescence readings was 0.753. The results indicate that the fluorescence camera appears to be a useful supplementary tool in assessing the endpoint of caries excavation with the advantage of enabling data to be digitally visualized and stored. When an experienced dental clinician determined the excavation endpoint, the performance with respect to remaining bacteria count was good.
