PURPOSE The Italian Society of Paediatric Dentistry (SIOI) is committed to encourage all dental practitioners to provide safe and updated prevention and treatment strategies for oral diseases in paediatric patients. SIOI promotes quality communication and information to parents and caregivers for prevention and awareness of oral diseases in the paediatric population. METHODS This Policy is based on a comprehensive review of the highest-quality scientific literature available over the past 20 years, including systematic reviews, meta-analyses, evidencebased guidelines, expert recommendations, manuscripts and best clinical practices. A bibliographic search was conducted using PubMed°/MEDLINE, using keywords such as: molarincisor hypomineralisation, molar hypomineralisation, enamel defect, hypomineralised molars, hypomineralised second primary molars, dental developmental defects. Search filters included: publication date (since 2001), language (English), fulltext availability, study type (systematic review, meta-analysis, clinical trial, evidence-based guidelines, manuscripts), species (humans), and age (child: birth-18 years). Additional references were obtained through citation tracking of key publications. Final recommendations were developed by combining the best available scientific evidence with clinical expertise and consensus from a multidisciplinary panel of paediatric dental specialists.
