Abstract
This study assessed different restorative materials in primary teeth over a one-year period. Sixty carious primary molars were selected from 30 patients; ages 5-10 years. Class I and II cavities were divided into four groups: Group I: 15 Class I cavities were restored with a compomer, Group II: 15 Class I cavities were restored with a resin composite, Group III: 15 Class II cavities were restored with a compomer and Group IV: 15 Class II cavities were restored with a resin composite. Each child had two teeth restored, one with compomer and the other with composite resin as control. Direct clinical and radiographic evaluations were performed by one examiner after 24 hours, 6- and 12-months. Indirect clinical evaluations were performed using a Scanning Electron Microscope after 24 hours and 12-months periodically. Clinical and radiographic evaluations revealed no significant differences between the compomer and resin composite at 6- and 12-months. Indirect clinical evaluation showed good marginal interfaces between the restorations and the tooth structure throughout the evaluation periods. Both materials presented significant clinical and radiographic performances in Class I and II restorations of primary molars after one year.
