Background: This study aimed to assess the attitude of parents and dentists about the restorative materials used in pediatric
dentistry. Methods: This study was performed on 157 parents of children referred to the dentist and 157 dentists in Iran. A
questionnaire was designed containing 8 questions for parents and a questionnaire containing 24 questions for dentists. At the
beginning of the questionnaires, questions were about demographic information, and in the next questions, parents' and dentist's attitudes about the restorative materials were evaluated. Results: In comparison of restorative materials, composite and amalgam
had the highest acceptability among parents, and the most concern was related to the durability of the composite and beauty of the
amalgam. Acceptability of stainless crown was less than that of amalgam and composites, and the esthetic of these crowns was the
most concerns of parents. Veneered crowns were the least acceptable for parents, and parents' greatest concern was for its cost and
durability. The selected material to restoration class II proximal cavities in dentists was amalgam. Only 3% of dentists never used
amalgam to restoration primary molars. In dentists’ opinion, the greatest concern for parents is durability and cost of the restorative
materials. The priorities for choosing the restoration materials for primary molars by dentists were 74% isolation ability, 24%
involvement of more than two surfaces of teeth, and 17% child cooperation and cavity size, respectively. Conclusion: While
composite and amalgam are the most acceptable restoration materials among parents, dentists mostly used amalgam to restore
primary molars. The acceptability of restorative materials and concerns about the use of restorative materials were different between
parents and dentists. Most dentists did not comply with parents’ wishes in the choice of restorative materials.
