BMP is essential for the success of root canal therapy. It is because this preparation eliminates infection and bacterial by-products. Prevention of reinfection is achieved via the fluid-tight root canal filling and a coronal restoration. Chemical disinfection and mechanical preparation are commonly known as chemo-mechanical or biomechanical preparation. But BMP is one of the challenging tasks in endodontic therapy. However, when you receive root canal therapy at a clinic that has an immense reputation, you won’t get any issue.

What is BMP in Root Canal Treatment?

Biomechanical preparation is the achievement of free access to the apical foramen via the root canal by mechanical means. It is directly related to subsequent disinfection and filling. It is because it creates enough space for medication and irrigation. The main aim of root canal preparation is to create a persistent tapered shape largest at the aperture and the smallest at the apical foramen. This will create better irrigation and filling.

Why Biomechanical Preparation is Performed?

When you consider skilled dentists at 21st Street Dental Group, they do biomechanical preparation well. All of them are highly knowledgeable of root canal dentistry in Colorado Springs and ensure that patients leave the office with a sweet smile. The main aim of BMP is to:

• To clean the root canal and pulp chamber of the bacteria, pulp tissue remains, toxins, foreign debris, altered dentin, caries, and saliva.
• To make the canal wall smooth as it will enhance the contact of the medication with the infected canal.
• To prevent periradicular disease or make healing fast in the area where it already exists
• To get rid of any metallic and non-metallic obstacles (in the case of retreatment)
• To prepare canal walls and apical stop to make obturation of root canal
• To enlarge the canal so that it gets the maximum amount of medication and irrigating solution.
• To preserve the location and integrity of apical canal anatomy
• To avoid iatrogenic damage to the root structure and canal system
• To preserve the root dentine for better functioning of the tooth

How the Dentist does BiomechanicalPreparation?

1. Firstly, the dentist gets rid of the pulp tissue fromthe root canal followed by the shaping of the root canal. The main purpose of shaping is to taper and enlarge the canal so that it receives obturating material well. They do it using endodontic instruments such as reamers and files.
2. Once the canal gets in its proper shape and wellcleaned, they perform obturation (means filling) via gutta-percha or other canal filling materials.

Stages of Biomechanical Preparation Biomechanical preparation of root canal involves threestages namely:

1. Mechanical Removal of Infected Dentin and Pulp Tissue 

Harmful bacteria are present in dentinal tubules, whichcreate bacterial toxins. These toxins are the offending agent for peri-apical pathology. Hence, it is important to get rid of the infected dentine and pulp tissue. This helps to irrigate solutions to reach and disinfect the root canal tubules effectively and deeply and kills the bacteria. Therefore, it ultimately disinfects the whole root canal system.

2. Irrigation of Root Canal 

The irrigation of the canal gets rid of the debris and gives the clean path for the insertion and working of instruments in the root canal system. Remember, irrigation process for single and multiple visits RTC does not have too much difference except for non-important teeth, where the last irrigation is performed by saline and dexamethasone blend to lower the chances of Phoenix reaction.

3. Intra-Canal Medicaments

This step involves the placement of medicines with goodbiocompatibility into the canals to hinder the coronal invasion of bacteria. These medicines disinfect the root canal in between two appointments. Remember, in the case of same-day and single visit RCT, the third element is of no use. The first and second steps are crucially important and depend on each other for the ultimate success of the procedure. Preparation of the root canal system one of the most crucial stages in root canal treatment. It includes the removal of necrotic tissues from the root canal system, along with infected root dentine, shaping, and apical preparation. Dentists use various methods and root canal instruments that have high precision and the shortest working time to achieve the primary goals of root canal preparation consistently. Mechanical preparation leaves a canal wall filled with debris and smear layer if not accompanied by proper irrigation with suitable solutions. That is why it is important to choose your dentist wisely. Each skilled root canal specialist at 21st Street Dental Group performs biomechanical preparation of the root canal of the patient by intense disinfection protocols using appropriate intracanal medicaments and irrigants.
