Dentistry has seen many breakthroughs in the last 30 years, both in materials and technologies. The introduction of Mineral Trioxide Aggregate (MTA) in the 1990s was pivotal in endodontics due to its anti-microbial ability, excellent biocompatibility, superior seal, and bioactivity. The use of MTA as primary monoblock root canal filling is considered ideal and is now gaining popularity with reported high success rates. This lecture aims to show the following:

• How MTA in endodontic obturations can cater to various clinical complexities and situations.
• Techniques of MTA compaction to optimize MTA obturation predictably.
• Ways to overcome the limitations and challenges of MTA as root canal filling
