IRCT20200531047611N1 IRCT 2020-07-06 Islamic Azad University Comparison of clinical efficacy of primary anterior restoration with two different types of post systems in severely damaged teeth Comparison of clinical efficacy of primary anterior restoration with two different types of post systems with reconstruction of severely damaged teeth in3-5 years old children 2020-07-22 anticipated 32 Complete https://irct.ir/trial/48790 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: The teeth of each patient were randomly selected to be repaired through a composite post or customized glass fiber post. The randomization method was that the side that started first was determined by a coin, and then it was decided on the treatment when opening a closed envelope, Blinding description: The consequence assessors were different from the therapist, and the assessor was not aware of the information of patients and the type of treatment taken on the teeth. The patient was not also informed of the type of treatment on the teeth. N/A Primary dental caries. Intervention 1: Intervention group: All treatments (pulpectomy and repair) were carried out by a therapist. In the first session of treatment, adequate anesthesia was imposed on teeth. Mechanical and chemical measures were prepared by rotary files (easyinsmile international cord-NITI Engine File, USA) (usually up to file number 30) and solutions such as normal saline. In the following, the canals were dried by paper points. Root canals would be filled by metapex paste (Metapex, META, Korea). In the second session, from the beginning of the canal, it was emptied by a fissure bar connected to angle number 008 (Tizkavan Company, Tehran, Iran) to create a post space of 4 mm. After cleaning and drying the layer post space, a 1 mm thick layer of optical glass ionomer cement (Willmann & Pein- Glass liner,Germany) was replaced (on metapex). Then 3 mm post space was standardized for all samples. After cleaning and rinsing 3 mm at the beginning of the canal, 1-2 second pure air was applied to dry the canal, and then bonding was carried out through the method of self-etching according to the factory instructions. 1-2 bonding drop (Bisco-ALL-BOND UNIVERSAL, USA) was rubbed in the canal in the form of two separate layers, and its additions were removed by pure air. Then, customized strip-shaped fibers (Angelus,Brazil) of customized glass fiber post was applied in accordance with factory instructions. 1-2 bonding drop (Bisco-ALL-BOND UNIVERSAL, USA) was rubbed in the canal in the form of two separate layers, and its additions were removed by pure air.Then, customized strip-shaped fibers (Angelus,Brazil) of customized glass fiber post was used in accordance with factory instructions. So that, 3 mm of it remained inside the canal, and the remaining (2mm) was placed outside of the canal as a core. Some 5 mm strip-shaped fibers were packed inside the canal along with a thin layer of resinous cement (Bisco-DOU-LINK UNIVERSAL, USA), until the space inside the channel was completely filled. After that, it was cured for 20 seconds by a dental light curing device with a power of 800 mw / cm2. To rebuild the crown, the enamel was etched for 15 seconds by 35% phosphoric acid (Scotchbond ™ Etchant, 3M ESPE, MN, USA). Bonding was applied in the same way as addressed above and after 10 seconds of curing, and the crown was restored by microhybrid composite (Bisco-AELITE ALL / PURPOSE BODY, USA) and the method of incremental. Intervention 2: Control group:All treatments (pulpectomy and repair) were carried out by a therapist. In the first session of treatment, adequate anesthesia was imposed on teeth. Mechanical and chemical measures were prepared by rotary files (easyinsmile international cord-NITI Engine File, USA) (usually up to file number 30) and solutions such as normal saline.

The composite was then utilized as a post (as a control group). In this group, after applying the bonding in the same mentioned method and its curing for 20-30 seconds (based on factory instructions), one layer of flow composites (Bisco- AELITEFLO /AELITEFLO LV,USA) was placed inside the canal and was layered up to a height of 3 mm. The crown rebuild was performed by microhybrid composite.
