The comparison of survival and failure types of composite resin restorations under general anesthesia of primary anterior teeth using two methods, glass fiber posts or reversed- oriented metal posts as canal retention

Abstract

Introduction: Restoration of the anterior severely damaged teeth with the help of a variety of intra-channel ducts such as inverted metal pins and glass-fiber posts are among the methods that have been widely considered today. Therefore, the aim of this study was to compare the survival rate and type of fracture of composite restorations of severely damaged anterior teeth with inverted metal pins or glass-fiber posts in a 3-year period from 2014 to 2017 years. Methods and materials: The population of this double-blinded study consisted of 368 intensely damaged maxillary incisors teeth in the period from 2014 to 2017. Of these, 156 teeth were treated with systemic gland in the glass-fiber post and 212 intra- channel system Metal pin in reverse. The follow up of patients during the years 2014 and 2015 was done for more time, in the period of 24 months and 36 months, and in the years 2016 and 2017, only a 24-month follow up was performed and the number and type of fracture of each treatment were evaluated. This study analyzed using descriptive statistics (mean ± standard deviation and frequency (percentages)) by SPSS software version 24 and significant level was considered as (P <0.05). Result: The results showed that there was a significant difference between the number of fractures (P = 0.021) and the type of fracture between the two groups (P <0.001) in the follow up period of 24 months. However, there was no significant difference in the number and type of fractures among the participants between the years of study (P = 0.067). Discussion: The results of this study showed that there was a significant difference between the number of fracture and the type of fracture between the two study groups and the rate of treatment fracture in the teeth that were used as a retractor of the metal in the channel was less.
