Contemporary Restorative Materials in Primary Molars

Clinical Evaluation of Contemporary Ion Releasing Restorative Materials in Primary Molars Subjected to Selective Caries Removal: A Randomized Clinical Trial

This randomized controlled trial aims to compare the clinical effectiveness of four ion-releasing restorative materials in the proximal cavities of primary molars that underwent selective caries removal. The main questions to answer are:

• Will there be any difference among the restorative materials clinical succes in the means of modified United States Public Health Services (USPHS) criteria for dental restorations?
• Will there be any difference among the restorative materials in the means of preservation of pulpal vitality? Eighty six children (262 teeth), between 5 and 9 years old (7.15±1.14) enrolled for the study. Researchers will compare the clinical performance of restorative materials, (1:Equia Forte HT; 2: Fuji II LC; 3: Cention N; 4: ChemFil Rock), applied to the proximal cavities of primary molars following selective caries removal, according to the modified USPHS criteria.

Participants will:

- visit the clinic 1st,3rd,6th,12th,18th,24th,30th and 36th months after the restoration.

Inclusion Criteria:

For participants:

• no known or suspected history of allergy to medications or restorative materials
• no habits of teeth grinding or clenching
• presence of at least one interproximal carious lesion

For teeth:

• carious lesion reaching at least 1/2 dentin
• in contact with adjacent teeth and in occlusion with antagonist teeth
• have no pathological mobility
• periodontally healthy
• no symptoms of pulpal pathology
• physiological root resorption should not exceed one-third of the root length if seen
• permanent tooth germ present below the tooth

Exclusion Criteria:

• did not attend their follow-up appointments
