Management and Diagnosis of Developmental Defects of Enamel
Defect of matrix formation
Enamel hypoplasia
Defect of initial calcification
Enamel hypomineralisation (quantitative defect
Management
Prevention, Remineralisation and Desensitisation
Reduction in cariogenic and erosive foods/drinks
Tooth pastes (1000ppm Fl) + Topical fluoride (Fluoride Varnish 22 600ppm F, Gel Kam 1 000ppmF)
Tooth mousse
Hypomineralised permanent incisors
Microabrasion
Composite restorations (veneers/crowns)
Resin infiltration
Porcelain veneers/crowns
Etch-bleach-seal technique
External bleaching
Hypomineralised first permanent molar
Amalgam (not recommended due to atypical outline form)
GIC (not recommended due to poor wear resistance)
Composite resin (class 1 or 2 not involving cusps)
Stainless steel crowns (provide full coverage and eliminates sensitivity)
Laboratory-made adhesive or cast crowns (provide full coverage with excellent fit but requires 2 visits + more expensive)
Extraction (optimal timing between 8.5 and 10.5 years of age)
Consequences
Maxillary First Permanent Molars
Class I molar relationship - Mandibular FPM will rarely overerupt
Class II molar relationship - Mandibular FPM may overerupt
Mandibular First Permanent Molars
Mesial tilting and lingual rolling of 2nd permanent molar
Overeruption of opposing FPM if there are no occlusal stops
Incomplete space closure or formation of poor mesial contact
Distal drifting and tilting of 2nd premolar
Atrophy of alveolar bone is space closure is incomplete
Defect of final maturation
