APEXIFICATION WITH MINERAL TRIOXIDE AGGREGARTE, COLLAGEN MATRIX AND Er,Cr:YSGG LASER: A CASE STUDY

Abstract

Apexification is considered the treatment of choice for necrotic young permanent teeth with immature, open apices. This case study evaluates apexification completed on a previously treated permanent tooth of a 17-year old patient showing signs of symptomatic periradicular periodontitis. Apexification procedure was completed with the help of Er, Cr:YSGG laser and placement of Mineral Trioxide Aggregate (MTA) to allow for healing of periradicular tissues and disinfection of the canal system. Collagen matrix was used prior to placement of MTA to avoid extrusion of material in the periradicular tissues. One-year follow-up revealed significant healing of periradicular tissues and absence of any clinical signs and symptoms. This report provides an option of performing apexification procedure in combination with laser disinfection as opposed to past strategies which relied on chemical disinfection. This is aimed to increase long-term prognosis of the tooth.
