Abstract
This study aimed to systematically review the literature to address the question regarding the influence of different materials in the clinical and radiographic success of indirect pulp treatment in primary teeth. A literature search was carried out for articles published prior to January 2017 in PubMed/MEDLINE, CENTRAL, Scopus, TRIP and ClinicalTrials databases; relevant articles included randomized clinical trials that compared materials used for indirect pulp treatment in primary teeth. Two reviewers independently selected the studies and extracted the data. The effects of each material on the outcome (clinical and radiographic failures) were analyzed using a mixed treatment comparisons meta-analysis. The ranking of treatments according to their probability of being the best choice was also calculated. From 1,088 potentially eligible studies, 11 were selected for full-text analysis, and 4 were included in the meta-analysis. In all papers, calcium hydroxide liner was used as the control group versus an adhesive system, resin-modified glass ionomer cement or placebo. The follow-up period ranged from 24 to 48 months, with dropout rates of 0-25.7%. The material type did not significantly affect the risk of failure of the indirect pulp treatment. However, calcium hydroxide presented a higher probability of failure. In conclusion, there is no scientific evidence showing the superiority of any material used for indirect pulp treatment in primary teeth.
Highlights
Submitted: May 05, 2017 Accepted for publication: Oct 09,2017 Last revision: Nov 07, 2017According to the guidelines of the American Academy of Pediatric Dentistry (AAPD), indirect pulp treatment is a procedure recommended for teeth with deep carious lesions without signs or symptoms of pulp degeneration.[1]
The main goal of this minimal intervention approach is based on modification of the microenvironment of the contaminated dentin, intentionally left under the restoration, thereby arresting the cariogenic process, while preserving the tooth structure and pulp vitality.[2]
Several materials have been used for indirect pulp treatment in primary teeth, such as calcium hydroxide liner,[4,5,6] dentin bonding agents[5,7] mineral trioxide aggregate[6], glass ionomer cement,[8] zinc oxide/eugenol,[9] calcium silicate[10] or medical Portland cement.[11]
