EVALUATION OF THE APICAL LEAKAGE OF SURROUND ENDODONTIC IMPLANTS CEMENTED WITH MTA IN VITRO
BACKGROUND AND OBJECTIVES: Endodontic implants are metalic extension of a tooth root using a post prepared for maintaining teeth that must be extracted. One of the most important factors of implant failures is improper apical seal between implant and end of root. The purpose of this study was to eva...

| description | BACKGROUND AND OBJECTIVES: Endodontic implants are metalic extension of a tooth root using a post prepared for maintaining teeth that must be extracted. One of the most important factors of implant failures is improper apical seal between implant and end of root. The purpose of this study was to evaluate the effect of MTA (mineral trioxide aggregate) on apical seal surround endodontic implants.METHODS: In this experimental in-vitro study twenty eight freshly extracted human maxillary central incisors and canines were used. After cleaning, all teeth were cast in putty and then removed from cast and cut from middle one third of the root. Access cavity was made and canals enlarged with hand instrumentation and piezoreamer drills in such manner that drills were extruded from apex. The teeth were replaced in the cast and buccal portion of the cast was removed. Teeth were randomly divided into two groups. In group A implants were placed at canals through access cavity and cement with glass ionomer cement. In group B before implant placement, MTA packed at the end of the canals then a tract were made within them. After MTA setting, implants were placed at the canals like group A and cemented with glass ionomer cement. Access cavity sealed and all surfaces of the teeth were covered with two layer of nail varnish except apical 2 millimeters. Dye penetration was measured using foshin solution. After splitting the teeth longitudinally, dye penetration was measured by stereomicroscope. FINDINGS: Average of dye penetration for group A and B is 0.32 and 0.22mm, respectively. The average of dye penetration in group A was significantly higher than group B (p<0.05).CONCLUSION: Application of MTA improves apical seal surround endodontic implants, thus increase successful rate of it. |
