Bonding agents are resin materials used for dental composite restorations. Dentin needs conditioning with polyacrylic acids to remove smear layer. Modern systems include three-step, two-step, and one-step bonding systems
MIH affects one to four permanent first molars with associated incisors. Global prevalence ranges from 13.1% to 14.2%. Affected teeth have reduced mechanical properties and increased caries risk
Class III involves proximal anterior teeth. Class IV affects proximal anterior teeth and incisal edge
MIH affects permanent first molars with or without incisors. Condition causes enamel defects with white to yellow/brown opacities. Various systemic, genetic and environmental factors contribute
Dental composites combine polymeric matrix with glass, mineral or resin fillers. Modern composites show 2-3% shrinkage during polymerization. Traditional composites contain large particles for good mechanical properties
MIH affects permanent first molars and incisors with demarcated enamel opacities. Defect prevalence ranges from 2.4% to 40.2% worldwide. Best age for cross-sectional studies is 8 years
