OverviewThe aim of this Guide is to describe the structure and facilitate the implementation of the InternationalCaries Classification and Management System (ICCMS ), which the authors propose to be used inthe daily handling of our patients for caries prevention and management and also in the teachingundertaken at dental schools around the world.The ICCMS is a health outcomes focused system that aims to maintain health and preservetooth structure. Staging of the caries process and activity assessment is followed by riskadjusted preventive care, control of initial non-cavitated lesions, and conservative restorativetreatment of deep dentinal and cavitated caries lesions.There are four elements in the ICCMS , the two key aspects are: Classification - Caries Staging & Activity Assessment: this comprizes (i) staging of caries lesionseverity (‘initial’/’moderate’/’extensive’) and (ii) caries activity assessment (likelihood of progression orarrest/reversal of lesions: ‘active’/’inactive’). [Note that during the intraoral assessment phaseinformation is also collected on oral risk factors; e.g. oral hygiene, dry mouth]Management - Personalized Caries Prevention, Control & Tooth Preserving Operative Care: Thedental team, together with the patient, devise a Personalized Caries Care Plan to manage the cariesrisk status of the patient as well as managing caries lesions appropriately. (i) Management of the riskstatus is based on both home care advice, as well as clinical activities; those with low risk gettinggeneral information on how to maintain teeth as sound, those with moderate and high risk withincreasing focus on behavior changes and short periods between recalls to the clinic. (ii) Themanagement of the lesions is related to the diagnosis of the individual lesions: ‘initial’ active lesions ingeneral are managed with non-operative care (NOC) whilst moderate/extensive lesions are in generalmanaged operatively with tooth preserving operative care (TPOC).In order to devise an optimal Personalized Caries Management Plan, two other elements are alsoneeded (please note that the chronological sequence and the method of integration of patient andclinical information may vary according to local preferences): History - Patient-level Caries Risk Assessment: collation of risk information at the patient level (tobe integrated with clinical and tooth level information).Decision Making - Synthesis and Diagnoses: (i) classification of individual lesions combininginformation about their stage and activity (e.g. ‘initial’ active lesion), and (ii) an overall caries risklikelihood status combining information about presence/absence of active lesion/s and patient’s risk(‘low’, ‘moderate’ or ‘high’ risk of getting future caries and/or of lesion progression).The risk-based recall interval, including monitoring and review, then allows this caries managementpathway to become a cycle, facilitating the achievement of optimal long-term health outcomes. Outcomes - are considered across: health maintenance, disease control, patient-centered qualitymetrics, as well as the wider impacts of using the ICCMS System.The authors hope that this Guide will be useful in bringing the International Caries Classification andManagement System - ICCMS - to the attention of many more clinicians and educators around theworld. We also hope that it will provide an indication of one way to operationalize the System. Thecharacteristics of ICCMS are the delivery of effective, risk based caries care that prevents newlesions, controls initial caries non-operatively and preserves tooth tissue at all times.The authors gratefully acknowledge the tremendous contributions of all the many parties who havecontributed to both the ICDAS Foundation and to the development of ICCMS .5

IntroductionThe International Caries Classification and Management System - ICCMSTM - deliberatelyincorporates a range of options designed to accommodate the needs of different usersacross the ICDAS (International Caries Detection and Assessment System) domains ofclinical practice, dental education, research and public health (see Figure 1). The ICCMSTMsystem seeks to provide a standardized method for comprehensive caries classification andmanagement, but recognizes fully that there are different ways for implementing suchsystems locally. ICCMS builds on the evidence-based ICDAS system for the staging ofcaries. It also maintains the flexible approach of the ICDAS “wardrobe” which providesseveral approved options for categorising the disease according to local and/or specificneeds, preferences and circumstances.It must be appreciated that this Guide relates only to the use of the System in the domains ofPractice and Education; there are a range of considerations and applications ofICDAS/ICCMS in Research and in Public Health that are important, but are beyond thescope of this Guide (see Figure 1).The system outlined in this document is based on best evidence and consensus. Themethodology used was wherever possible to use “SIGN” grading of the evidence with rapidreviews an
