136 anterior-teeth of 46 patients have been sealed for restoration and monitored. After 24 months, the results are 69.11% good at sealing surface, 67.64% at color, 72.06% at surgery and 58.08% at the integrity of the sea
Incisor ; Composite Resins

Composite resin has been used commonly in dentistry. Bonding the teeth with composite resin was based on two mechanisms: 1) The adhesion between composite and enamel, and 2) the adhesion between composite and dentine. The bond strength of these two mechanisms was compared in 1225 teeth after 2 years of bonding. The results showed that the first mechanism provided stronger bond than the second did.
Composite Resins ; Tooth

112 patients with 1089 teeth were covered directly. The results were evaluated after 6, 12, 18, 24 months of the treatment and have shown that the surface of the composite was good in 70.33% of patients, the fine color of the composite was 68.22%. The rate of anatomical success was 59.68% and the completion of the rear of composite was 67.30%.
Tooth ; Composite Resins ; therapeutics

Damages of anterior teeth that have filling need to be recovered in function. Remaking them by resin composite accompanied dentine element pin satisfied this requirement. The treatment provided for 16 teeth of 10 patients have showed the successful result.
