ORCA-EFCD consensus report on clinical recommendations for caries diagnosis. Paper II: caries lesion activity and progression assessment.

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 (CARS). 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.

ORCA-EFCD consensus report on clinical recommendation for caries diagnosis. Paper I: caries lesion detection and depth assessment.

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.

RoBDEMAT: A risk of bias tool and guideline to support reporting of pre-clinical dental materials research and assessment of systematic reviews.

OBJECTIVES: To develop a risk of bias tool for pre-clinical dental materials research studies that aims to support reporting of future investigations and improve assessment in systematic reviews. METHODS: A four-stage process following EQUATOR network recommendations was followed, which included project launch, literature review, Delphi process and the tool finalization. With the support of the European Federation of Conservative Dentistry (EFCD) and the Dental Materials Group of the International Association for Dental Research (DMG-IADR), a total of 26 expert stakeholders were included in the development and Delphi vote of the initial proposal. The proposal was built using data gathered from the literature review stage. During this stage, recent systematic reviews featuring dental materials research, and risk of bias tools found in the literature were comprehensively scanned for bias sources. The experts thus reached a consensus for the items, domains and judgement related to the tool, allowing a detailed guide for each item and corresponding signalling questions. RESULTS: The tool features nine items in total, spread between 4 domains, pertaining to the following types of bias: bias related to planning and allocation (D1), specimen preparation (D2), outcome assessment (D3) and data treatment and outcome reporting (D4). RoBDEMAT, as presented, features signalling questions and a guide that can be used for RoB judgement. Its use as a checklist is preferred over a final summary score. CONCLUSION: RoBDEMAT is the first risk of bias tool for pre-clinical dental materials research, supported and developed by a broad group of expert stakeholders in the field, validating its future use. CLINICAL SIGNIFICANCE: This new tool will contribute the study field by improving the scientific quality and rigour of dental materials research studies and their systematic reviews. Such studies are the foundation and support of future clinical research and evidence-based decisions.

How French dentists manage defective restorations: Evidence from ReCOL the French dental practice-based research network--A survey study.

OBJECTIVES: The objective of this study was to describe the knowledge, opinions and practices about the defective restoration (DR) management of French general dental practitioners (GDPs). METHODS: A cross-sectional, online survey-based study was carried out amongst 378 GDPs - members of the dental practice-based research network in France (ReCOL). Bivariate comparisons were made using Fisher's exact test to assess the association of the respondent characteristics (age, gender…) with the decision to repair DRs, and responses to clinical cases. RESULTS: The response rate was 82.9%. 50.4% of the respondents declared they at least sometimes consider DRs repair in their clinical practice instead of DRs total replacement. For the 89.8% who at least rarely repaired DRs, the main characteristic determining the therapeutic strategy was the defect size (71%, mainly inclined to repair small defects), followed by the defect type (marginal defect or crack for more than 60% of the respondents) and the material of initial restoration (composite for 63.5%). When shown clinical photographs illustrating DRs, most of respondents proposed a replacement with inlay/onlay or crown. CONCLUSIONS: This study indicates that a significant proportion of French GDPs do not make sufficient use of DR repair on a routine basis. A lack of knowledge of the concept seems to explain at least part of this situation. Collective and individual efforts from the profession are still needed to promote DR repair and therefore more often apply MinimalIntervention Dentistry. CLINICAL SIGNIFICANCE: This survey shows that MID is not yet sufficiently used in routine practice in France regarding DR management. Further efforts (continuing education toward MID, public funding revaluation for MID strategies…) are needed to help GDPs to implement MID into everyday practice.

Knowledge and Opinions of French Dental Students in Operative Dentistry - Management of Deep Carious Lesions.

PURPOSE: A questionnaire survey was recently undertaken among French dental students (FDSs) to investigate their practices, knowledge and opinions in various domains of minimal intervention (MI) in cariology. The present work focuses on management of deep carious lesions (DCLs). MATERIALS AND METHODS: The questionnaire was administered (Spring 2018) to all the fifth-year students of the 16 French dental schools. Descriptive analyses were performed. RESULTS: Among 1370 FDSs (response rate: 84.5%), hardness was the most commonly reported criterion for assessing the endpoint of carious tissue removal (53.9%), followed by firm dentin (40.0%). Regarding FDSs' opinion of leaving carious dentine under a restoration, 41.9% of the respondents agreed that carious tissues should always be removed completely. For an asymptomatic tooth with DCLs and exposed pulp, direct pulp capping was mainly chosen (93.9%). In a clinical case correctly diagnosed as a reversible pulpitis by 79.7% of respondents, nearly half of FDSs chose a one-step complete excavation (48.3%) followed by selective excavation (25.1%), then two-step complete excavation (20.9%) and a minority (5.7%) opted for pulpal therapy (biopulpotomy or endodontic treatment). CONCLUSION: The present results suggest an inadequate dissemination of MI concepts among FDSs towards DCL management. The present results show the need for a harmonisation and a reinforcement of teaching evidence-based MI according to the latest European recommendations.

Knowledge and Opinions of French Dental Students Toward Occlusal and Proximal Restorative Thresholds.

PURPOSE: To investigate the practices, knowledge and opinions of French dental students (FDSs) in various domains of minimal intervention (MI) in cariology. MATERIALS AND METHODS: A cross-sectional, questionnaire-based study was conducted in spring 2018 among all fifth-year French dental students (FDSs) from the 16 French dental schools. The present article focuses on restorative management. Statistical analyses (descriptive, chi-squared) were performed. RESULTS: The response rate was 84.5%. Overall, 97.4% of respondents would have operatively intervened for proximal and 83% for occlusal carious lesions, respectively, while non-or micro-invasive intervention would have been possible. Interestingly, 15% would completely open the occlusal fissures. For both occlusal and proximal lesions requiring a restoration, composite resin was indicated by over 95% of the respondents. In a clinical case, 51.6% of FDSs who rightly diagnosed an enamel carious lesion would operatively intervene. When FDSs could not diagnose the type of carious lesions, a high proportion of invasive actions were also reported (40%). FDSs who read scientific articles were more likely to consider the high importance of not filling sound teeth unnecessarily (p = 0.033). CONCLUSION: FDSs do not have sufficient awareness of MI guidelines regarding occlusal and proximal restorative thresholds. Efforts are required in dental schools to teach FDSs to postpone invasive/restorative strategies to later stages of carious progression. There is a need to strengthen prevention techniques and non-invasive options in the teaching of MI in cariology.

A study of 84 homemade toothpaste recipes and the problems arising from the type of product.

Objective Growing consumer mistrust of a number of ingredients used in industry has led to the development of a trend for homemade products. This now affects all types of sectors, but particularly the hygiene sector for shampoo and toothpaste products. The aim of this work is therefore to study recipes found on the internet for these types of products in order to assess risks associated with their use.Materials and methods Eighty-four recipes were collected from the internet and their composition was analysed.Results None of the 84 formulas analysed contained any fluoride salts, well known for their oral health benefits. Eighty percent did not contain a foaming agent either, which is very useful in the cleaning function of toothpastes. Furthermore, the quantities of substances to be used were usually expressed in tablespoons or teaspoons, measures which are imprecise and could, for example, lead someone to use large quantities of an abrasive agent such as calcium carbonate.Conclusions Attention should be drawn to homemade toothpaste recipes that contain no fluoride and whose abrasivity, purity and microbial contamination cannot be verified.

A Comparison of Four Caries Risk Assessment Methods.

Introduction: Caries risk assessment (CRA) is essential as the basis for successful management of dental caries. Of the many published CRA tools, four well-known ones are CAMBRA, Cariogram, American Dental Association (ADA), and American Academy of Pediatric Dentistry (AAPD) CRAs. The predictive accuracy of CAMBRA and Cariogram CRA tools have been examined in clinical outcomes studies in thousands of patients and the tools are widely used all over the world. The purpose of the present paper is three-fold, namely (1) to briefly review, compare and contrast these four CRA methods, (2) to provide a concise method for CRA introducing a quantitative component to the CAMBRA forms (CAMBRA 123), and (3) to guide the choice of CRA methods that will support caries management decisions. Comparison of Caries Risk Assessment Methods: In the present evaluation, the above-mentioned four CRA methods for ages 0-6 years and 6 years-adult were compared using 26 hypothetical patients (13 per age group). Comparison results show that Cariogram and CAMBRA categorized patients into identical risk categories. Each of the ADA and AAPD tools gave different results than CAMBRA and Cariogram in several comparison examples. CAMBRA 123 gave the same caries risk level results as the Cariogram and the CAMBRA methods for all hypothetical patients for both age groups. Conclusions: Both the Cariogram and the CAMBRA CRA methods are equally useful for identifying the future risk of dental caries. CAMBRA 123 shows promise as an easy-to-use quantitative method for CRA in clinical practice. The health care providers will be the ones to decide which CRA method will allow them to establish individualized, successful caries management therapies and how to combine these for the best care of their patients.

Evidence-Based Caries Management for All Ages-Practical Guidelines.

Introduction: The purpose of the present paper is to provide step-by-step guidelines for dental healthcare providers to manage dental caries based upon caries risk assessment (CRA) for ages 0-6 years and 6 years through adult. The manuscript reviews and updates the CAMBRA (caries management by risk assessment) system which includes CRA and caries management recommendations that are guided by the assessed risk level. Caries Risk Assessment: CAMBRA CRA tools (CRAs) have been evaluated in several clinical outcomes studies and clinical trials. Updated CAMBRA CRAs for ages 0-6 years and 6 years through adult are provided. These CRAs have been refined by the addition of a quantitative method that will aid the health care provider in determining the caries risk of individuals. Caries Management Based Upon Risk Assessment: Guidelines for individualized patient care are provided based upon the caries risk status, results of clinical exams and responses of the patient to questions in the CRA. These guidelines are based upon successful outcomes documented in several clinical outcomes studies and clinical trials. The paper includes a review of successful caries management procedures for children and adults as previously published, with additional emphasis on correct use of silver diamine fluoride (SDF) for children. The caries management plan for each individual is based upon reducing the caries risk factors and enhancing the protective factors with the additional aid of behavior modification. Beneficially altering the caries balance is coupled with minimal intervention restorative dentistry, if appropriate. These methods are appropriate for the management of dental caries in all patients.

Knowledge and opinions of French dental students related to caries risk assessment and dental sealants (preventive and therapeutic).

OBJECTIVES: A national questionnaire study was performed to document knowledge and opinions of French dental students (FDSs) about minimal intervention (MI) in dentistry especially caries risk assessment (CRA) and dental sealants (DSs). MATERIALS AND METHODS: A questionnaire was administered to the fifth-year dental FDSs (n = 1370) from the 16 French dental schools. Descriptive and statistical analyses were performed. RESULTS: The response rate was 84.5%. A large majority of respondents (87.8%) linked MI with minimally invasive dentistry and 77.4% considered MI as a concept based on prevention. About 80% stated they use CRA in clinical practice, mostly without any specific form. If 80.4% of the respondents would base their treatment plans on CRA, only 55.1% would regularly plan preventive regimens according to individual risk level. However, while 96.6% declared they perform preventive DSs, only 44.3% considered therapeutic sealants as a routine treatment. Although 75.1% of FDSs stated that they had sufficient learning and training related to CRA, 55.9% thought that they need further education about preventive and therapeutic DSs. CONCLUSION: Although FDSs seem to be aware of the importance of CRA and preventive strategies, this study shows the need to harmonize the teaching in cariology according to the latest European recommendations. CLINICAL RELEVANCE: A national questionnaire study showed variability towards knowledge and opinions of FDSs related to MI in cariology. This may impact care provisions in their future professional life showing the urgent need to harmonize the teaching of MI in cariology in France.

Restorative thresholds for primary and permanent molars in children: French dentist decisions.

BACKGROUND: Worldwide, numerous surveys have investigated practices and knowledge about caries management in adults, but few are available for children. AIM: The present cross-sectional survey aimed to assess the restorative thresholds (RTs) in primary and permanent molars in children used by a population of dentists treating children and practicing in France. DESIGN: The study population consisted of French dentists treating children (Fr-DTCs) who were registered in the French Society of Pediatric Dentistry (n = 250). A specific questionnaire was developed. Descriptive and statistical analyses were performed. RESULTS: Response rate was 80.4% (n = 201). Considering that an appropriate RT is at the stage of a moderate lesion (occlusal: International Caries Detection and Assessment System 4; approximal: lesion involving the external third of dentine), more than 50% of respondents showed a tendency for iatrogenic treatment, except for occlusal carious lesions in primary molars. Inappropriate invasive strategies were more often reported for occlusal lesions in permanent than primary molars. Moreover, for both molar types, these inappropriate RTs were more often chosen for approximal than occlusal lesions. CONCLUSIONS: The present survey suggested that Fr-DTCs tend to overtreat in terms of caries management in both primary and permanent molars.

How to Intervene in the Caries Process in Older Adults: A Joint ORCA and EFCD Expert Delphi Consensus Statement.

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.

Validity of Soprolife camera and Calcivis device in caries lesion activity assessment.

Aim An ex vivo study was performed to assess (gold standard [GS]: Nyvad criteria) sensitivities (SEs) and specificities (SPs) of Soprolife (fluorescence) and Calcivis (bioluminescence) - indicated, by the manufacturers, for activity assessment of coronal carious lesions (AACCL). We also calculated the positive and negative predictive values, positive and negative log-likelihoods, inter-examiner and intra-examiner variations, and concordance rates (CRs) of both devices compared to GS and to each other.Materials and methods One hundred and twenty-one extracted posterior teeth were included. Within 48 hours after extraction, ICDAS and Nyvad scores were determined and occlusal photographs (Soprolife and Calcivis captures) were taken. Three examiners were asked to score, independently, twice (T0; T0 + 15 days), the caries activity status (active/inactive) for each image.Results Both devices showed modest SEs and SPs. The only statistically significant differences between devices were for SE (p = 0.04) in favour of Soprolife (all ICDAS scores combined) and for SP (p = 0.03) in favour of Calcivis (ICDAS 3, 4). There were higher CRs for Soprolife than for Calcivis (compared to GS). Intra- and inter-examiner variations were 76-86.8% and 71.9-85.1% for Soprolife, and 79.3-89.3% and 72.7-86.8% for Calcivis, respectively.Conclusion In light of the results, it seems difficult to confirm the validation of Soprolife and Calcivis for AACCL.

Knowledge and Use of Caries Risk Assessment for Adult Patients Croatian Dentists.

OBJECTIVE: The aim of this study was to evaluate the usage of caries risk assessment (CRA) by Croatian general practitioners and evaluate their knowledge and attitudes towards CRA. MATERIAL AND METHODS: A link to an online questionnaire was sent via e-mail to a sample of 1,500 general dentists in Croatia. The obtained data were analyzed using descriptive statistics, logistic regression analyses and chi-square tests. RESULTS: Of 257 respondents, 47% performed CRA routinely, but only 4.5% of them used a specific CRA form. The significance of different factors in the development of a treatment plan varied considerably among respondents. Furthermore, in 77% of the respondents CRA was a basis for planning individual caries prevention (ICP). The association between CRA and ICP, and between CRA and treatment planning was statistically significant (p=0.001). The practitioners doing CRA more often plan their treatment and ICP according to CRA. The use of CRA was not influenced by specialty and dentists' experience. CONCLUSIONS: In a considerable percentage (53%) of Croatian general dentists, CRA is not part of their routine practice, and there is a strong association between the use of CRA and treatment plans and ICP. There is a need to promote the use of CRA in daily dental practice in Croatia.

How to intervene in the caries process in adults: proximal and secondary caries? An EFCD-ORCA-DGZ expert Delphi consensus statement.

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.

How to Intervene in the Caries Process in Children: A Joint ORCA and EFCD Expert Delphi Consensus Statement.

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.

Dentists' decisions for deep carious lesions management in primary teeth.

BACKGROUND: Questionnaire surveys have been undertaken worldwide to investigate practices and knowledge related to deep carious lesion (DCL) management in permanent teeth, and there is a lack of data in primary teeth. AIM: A cross-sectional questionnaire survey was undertaken to describe the management strategies for DCL of vital primary teeth, focusing on the different caries removal techniques, among dentists practicing pediatric dentistry (DPPDs) in France. Their behavior was compared to members one registered to European Academy of Pediatric Dentistry (EAPD). DESIGN: A questionnaire was electronically administrated (2018-2019) to members of the Collège des Enseignants en Odontologie Pédiatrique (CEOP), the Société Française d'Odontologie Pédiatrique (SFOP), and the EADP. Descriptive and statistical analyses were performed. RESULTS: Response rate was, respectively, for CEOP, SFOP, and EAPD about 74%, 29%, and 15%. About half of the respondents (53%) would perform a complete caries removal into one step when 12% would indicate a stepwise technique: 68% of the DPPDs practicing in France would perform complete caries removal in one step when the preferred option in the other EAPD members was the selective excavation (44%) (P < .001). CONCLUSIONS: Complementary education of French dentists in the domain of caries management appears necessary regarding current recommendations.

Restorative intervention thresholds and treatment decisions of general dental practitioners in London.

Introduction Minimally invasive dentistry has been promoted as the contemporary approach to the operative management of dental caries. Operative intervention should be undertaken on cavitated lesions which are actively progressing. However, there may be large variability in the restorative intervention thresholds and care plans of general dental practitioners (GDPs).Aims To investigate restorative threshold and treatment decisions for occlusal and proximal carious lesions in a cohort of GDPs in London. To investigate potential differences based on number of years since graduation and attendance on a caries management course.Materials and methods A previously used, validated caries questionnaire was distributed to foundation dentists, general practice dentists and practising educational supervisors in NHS London dental practices. Results Two hundred and seventeen GDPs participated in the study. For occlusal lesions, nine (9.1%) newly-qualified dentists selected to intervene surgically on lesions confined to enamel, compared to 24 (29.8%) dentists who have been qualified for more than five years (p <0.05). In addition, a greater number of dentists who had attended a training course were more likely to do a minimally invasive preparation for a proximal lesion (38.2%), compared to 19.8% of those who had not (p <0.05). The majority of all participants (74.2%) chose to restore a proximal lesion using resin composite. Despite this material choice, 58.5% of those graduating within five years opted to prepare a traditional Black's class II cavity. Conclusion A practitioner's restorative intervention threshold and their choice of treatment appears to be negatively affected by the number of years post-qualification, and positively influenced by attending a caries management course.

CariesCare practice guide: consensus on evidence into practice.

This CariesCare practice guide is derived from the International Caries Classification and Management System (ICCMS) and provides a structured update for dentists to help them deliver optimal caries care and outcomes for their patients. This '4D cycle' is a practice-building format, which both prevents and controls caries and can engage patients as long-term health partners with their practice. CariesCare International (CCI™) promotes a patient-centred, risk-based approach to caries management designed for dental practice. This comprises a health outcomes-focused system that aims to maintain oral health and preserve tooth structure in the long-term. It guides the dental team through a four-step process (4D system), leading to personalised interventions: 1st D: Determine Caries Risk; 2nd D: Detect lesions, stage their severity and assess their activity status; 3rd D: Decide on the most appropriate care plan for the specific patient at that time; and then, finally, 4th D: Do the preventive and tooth-preserving care which is needed (including risk-appropriate preventive care; control of initial non-cavitated lesions; and conservative restorative treatment of deep dentinal and cavitated caries lesions). CariesCare International has designed this practice-friendly consensus guide to summarise best practice as informed by the best available evidence. Following the guide should also increase patient satisfaction, involvement, wellbeing and value, by being less invasive and more health-focused. For the dentist it should also provide benefits at the professional and practice levels including improved medico-legal protection.
