Pulpectomy is the complete removal of the pulp tissue from the pulp chamber and root canals of a tooth. This procedure is the standard treatment for irreversible pulpitis, as the inflamed and infected pulp cannot heal and must be entirely removed to save the tooth and prevent further infection.

Loose crown: May cause discomfort but usually not pain on percussion or mobility of the tooth itself.

Tooth fracture: Can cause pain, but mobility is not a typical feature unless the fracture is severe.

Psychosomatic: Pain perception without clinical findings, but here mobility is present, so it’s not psychosomatic.

Eccentric contact: Premature or abnormal occlusal contact leads to trauma from occlusion. This causes inflammation in the periodontal ligament, resulting in pain on percussion and slight mobility.

Explanation: Furcation perforations occur in the area where the roots of a multi-rooted tooth diverge. These perforations are particularly challenging to manage because they can lead to periodontal disease and loss of attachment in the furcation area. The prognosis is poor due to the difficulty in achieving adequate sealing and maintaining periodontal health in this area, making it more susceptible to infection and further complications.

The dental pulp, a highly vascularized connective tissue, responds to any form of injury or insult (such as trauma, chemical irritation, or bacterial invasion from caries) with an inflammatory reaction, also known as pulpitis.

Explanation: Protruded anterior teeth are more susceptible to trauma and fractures due to their position and exposure. This anatomical relationship highlights the importance of considering tooth positioning in dental trauma cases.

Cracked tooth syndrome is effectively diagnosed through a combination of methods, primarily focusing on the patient's symptoms and specific clinical tests.

Explanation: According to the WHO classification of dental injuries, pulp exposures due to crown fractures are classified under 873.62. This classification helps in standardizing the terminology used in dental trauma, allowing for better communication and understanding among dental professionals.


873.60 - Pulp Exposure due to Trauma

This code refers to cases where the pulp is exposed as a result of trauma to the tooth. It does not specify whether the pulp is vital or non-vital, but it indicates that there is a direct exposure of the pulp tissue.

873.61 - Avulsion of Tooth

This code is used for cases where a tooth has been completely displaced from its socket (avulsed). In avulsion cases, the pulp is typically exposed, and immediate re-implantation is critical for the best prognosis. This classification highlights the severity of the injury and the need for urgent treatment.
873.62 - Crown Fracture with Pulp Involvement

This code refers to fractures of the crown of the tooth that involve the pulp. It indicates that the fracture has extended into the pulp chamber, necessitating treatment such as root canal therapy.

873.63 - Crown Fracture without Pulp Involvement

This code is used for crown fractures that do not involve the pulp. In these cases, the injury is limited to the enamel and dentin, and the pulp remains intact.

Endodontic treatment can be performed without removing orthodontic appliances. Access can be gained through the lingual surface or by carefully working around brackets. Removing arch wires interrupts orthodontic treatment unnecessarily.

Endodontic failure in maxillary first molars is often attributed to the complex canal morphology, particularly the mesiobuccal root. The inability to identify and appropriately treat all existing canals, specifically the second mesiobuccal (MB2) canal or "fourth canal," is considered a primary reason for root canal treatment failure

Hemisection involves cutting the tooth through the bifurcation and removing one root with its associated crown portion. This is appropriate when one root has severe periodontal or carious involvement while the other root is healthy.
