{"doi":"10.1111/jphd.12648","title":"Training protocol and calibration of the International Caries Detection and Assessment System in a school‐based clinical trial of elementary school‐age children","abstract":"OBJECTIVES: This paper demonstrates International Caries Detection and Assessment System (ICDAS) training procedures and inter/intra-examiner reliability for lesion severity, activity, and filling criteria in an elementary school setting. METHODS: ICDAS training was conducted in December 2021 prior to a school-based cluster-randomized controlled trial. A total of 59 children (6-8 years old) in grades 1-2 from one school in Houston, Texas were recruited. Two licensed dentists received a 5-day training from an ICDAS trainer at the participating school. Thirty-eight children were evaluated at least once by each dental trainee, and 18 had repeat examinations. The ICDAS criteria were used to classify dental caries lesion severity (0-6), lesion activity (active/inactive), and filling material (0-9) of all visually available primary and permanent tooth surfaces. Inter and intra-examiner reliability between each dental trainee and the \"gold standard\" trainer was evaluated using Kappa statistics. RESULTS: For lesion severity, the examination indicated an inter-rater weighted Kappa of 0.77 (95% CI 0.71-0.82) and 0.82 (95% CI 0.77-0.87) for each trainee examiner compared to the gold standard examiner. The Kappas increased slightly from the first to second examinations (lesion-weighted Kappa: 0.76 to 0.84 and 0.82 to 0.84). The intra-rater reliability indicated excellent reliability for lesion and filling (0.83 to 0.94) and moderate for activity (0.58). CONCLUSIONS: ICDAS training/calibration were essential to ensure accuracy and reliability of dental caries measurements. The study demonstrated that ICDAS training of dentists with no prior criteria experience is feasible in a community setting and can lead to high reliability and repeatability.","journal":"Journal of Public Health Dentistry","year":2024,"id":482539,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9316,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2024-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":929766,"name":"Dania Mofleh","orcid":"0000-0001-5269-978X","position":1,"is_corresponding":false},{"id":929764,"name":"Ru‐Jye Chuang","orcid":"0000-0003-1711-5800","position":2,"is_corresponding":false},{"id":400655,"name":"Mengxi Wang","orcid":"0000-0002-8528-5951","position":3,"is_corresponding":false},{"id":930318,"name":"Kila Johnson","orcid":null,"position":4,"is_corresponding":false},{"id":1323500,"name":"Alejandra Garcia‐Quintana","orcid":null,"position":5,"is_corresponding":false},{"id":1323501,"name":"Tolulope Titiloye","orcid":null,"position":6,"is_corresponding":false},{"id":432277,"name":"Suchitra Nelson","orcid":"0000-0002-1204-7020","position":7,"is_corresponding":false},{"id":104615,"name":"Shreela V.
