Reasons for Root Canal Treatment
There are several reasons why a tooth may require root canal treatment:

- Deep decay: Bacteria from tooth decay can penetrate deep inside the tooth and infect the pulp. Left untreated, this infection will spread and cause pain or swelling.

- Cracked teeth: Small cracks in teeth can allow bacteria to enter the pulp chamber and cause an infection.

- Trauma from an accident: A hard blow to a tooth may cause cracks or pulp damage, leading to infection over time if not addressed.

- Recurrent abscesses: In some cases, an infection may persist after a tooth becomes non-vital, necessitating root canal treatment to eliminate ongoing infection.

- Prior dental treatment: Deep fillings or over-aggressive dental treatments may accidentally expose or otherwise damage the pulp over time.

Evolution of Root Canal Files Instruments
The tools and techniques used for Root Canal Files treatment have advanced dramatically in recent decades. Traditional stainless steel hand files have largely been replaced by nickel-titanium (NiTi) engine-driven file systems. Some key developments include:

- Use of NiTi alloy: Nickel-titanium alloy is highly flexible but can also be twisted without permanently deforming. This makes NiTi files much more efficient at cleaning complex canal shapes compared to stainless steel.

- Trends toward single-use files: Disposable NiTi file systems are increasingly favored over reusable stainless steel counterparts due to superior sterility and reduced risk of file separation.

- Introduction of rotary NiTi files: Coupling NiTi alloy to small electric motors allows files to be rotated within the canal for enhanced debridement. This saves considerable time over hand filing.

- Progressive tapered file design: Contemporary file systems feature increasingly tapered and flexible files that flare from small to large diameter within the canal. This helps maintain the original canal shape.

- Shaping and cleaning in single appointment: New techniques and motor-driven systems allow the vast majority of cases to be successfully treated in one appointment versus multiple visits.
