Laser-assisted root canal treatment

The necessity for the root canal treatment takes place when the bacteria invade the pulp. Sometimes, the innermost structure of the tooth called pulp exposes to the surroundings due to other factors. Such conditions also might require root canal treatment. In any of the above cases, there are chances for the pulp with bacterial invasion. A successful root canal treatment requires complete sterilisation of the pulp canal. Laser-assisted RCT acts as an excellent adjuvant in cleaning and disinfecting the pulp canal along with the conventional RCT procedure. 


Laser-assisted root canal treatment:


With recent technologies, it is possible to open the canal without drilling the tooth. Lasers are a high energy beam that can penetrate into the tooth structure, in a controlled manner. It can able to remove soft and hard tissue debris, kills the bacteria and sterile the canal effectively. 


Benefits of laser-assisted root canal treatment:


Effective sterilisation of the canal:


The laser has bacteriocidal property. It can kill the bacteria efficiently compared to other conventional methods. It also removes the debris and irrigates the canal, thereby helping to clean the canal from free of microbes. 


The high success rate for root canal treatment:


Since the laser can effectively kill the bacteria, the chances for RCT failure is very minimal or nil. Most often, the failure of RCT occurs only when the canal is not sterile. If it gets re-infect because of an inadequate seal, or because of the untreated accessory canal, it would spoil the treatment. However, the use of a laser can nullify these failure possibilities. 


Minimal discomfort:


Compare to conventional treatment, the laser-assisted RCT has minimal discomfort as this procedure can remove all the debris and infection in single-shot. 


Biocompatible with the biological tissue:


The laser beam is highly biocompatible with tooth and its inner structure. This it will not give any adverse reactions to the tooth or to the surrounding structures. In fact, the energy beam from the lasers are easily absorbed by the biological tissue in a controlled manner, thus minimise the treatment time.


The disadvantage of laser-assisted RCT :


As the laser is light energy, it travels in the straight line. Unfortunately, some of the canals in the tooth are curvy and not straight. This would hinder the laser beam to reach until the end. However, when it is combined with conventional irrigant materials like sodium hypochlorite, the success rate of RCT is enormous. 




The laser acts as an excellent adjuvant for root canal treatment. When it is coupled with the conventional method, it is highly possible to create a purified environment inside the tooth canal. This factor is much essential for a successful root canal treatment.

Hi, about me....i am a dentist and would always like to be simple. When coming to profession, i like to learn and explore the hidden and unknown things...writing blogs helps me to keep updated as well :). Life is too short to waste and worry about. Be simple,act wise and make it meaningful. I believe, It is worth to plant a tree rather than building a mall.
