What is pulpal obliteration?
Pulp canal obliteration(PCO) is seen commonly in dental pulp after traumatic tooth injuries and is recognized clinically as early as 3 monthly after injury. Pulp canal obliteration is characterized by deposition of hard tissue within the root canal space and yellow discoloration of the clinical crown.
What causes pulp obliteration?
Summary Pulp canal obliteration (PCO) occurs commonly following traumatic injuries to teeth. Approximately 4–24% of traumatized teeth develop varying degrees of pulpal obliteration that is characterized by the apparent loss of the pulp space radiographically and a yellow discoloration of the clinical crown.
What is extirpation of pulp?
Extirpation is the removal of the infected pulp from the tooth. The dentist will drill an opening in the tooth to access the pulp chamber and root canal(s).
How is pulp extirpation done?
A small hole is drilled in the top using a laser. Your dentist will perform the pulp extirpation and remove all the infected matter from inside the tooth shell. The inside of the tooth will be cleaned thoroughly to remove any sign of infection. The tooth is filled with permanent filling material and then sealed.
What is pulp chamber?
What is a pulp chamber? Your tooth pulp is found in the hollow center of your tooth. This hollowed out area is divided into two parts: your pulp chamber and your root canal. Your pulp chamber is the hollowed-out space in the body or crown of your tooth, and your root canal is the section that extends down the root.
How do pulp stones form?
Pulp stones with regular calcification grow in size by addition of collagen fibrils to their surface, whereas the irregular type of pulp stones are formed by calcification of pre-existing collagen fibres. Pulp stones may also form around epithelial cells such as remnants of Hertwig’s epithelial root sheath.
What is difference between pulpotomy and pulpectomy?
In pulpotomy, the coronal part of the pulp is removed while in Pulpectomy procedure, the crown and the root canal of the pulp chamber is removed. For further understanding, Pulpotomy is a common procedure and can be referred to as baby root canal. Pulpotomy restores and saves the tooth infected by a deep cavity.
What is inside the pulp?
Your tooth pulp is the innermost layer of your tooth that contains nerves and blood vessels. Your tooth pulp is protected by layers of dentin and enamel. However, tooth decay or injuries to your tooth can expose your pulp and make it susceptible to infection.
What is the function of the pulp?
Put simply, the main four functions of the pulp are formation and nutrition of the dentin, as well as the innervation and defense of the tooth. Dentin formation is one of the most critical roles carried out by the pulp and, as mentioned, is formed by the odontoblasts.
What is the pulp?
The pulp is the connective tissue, nerves, blood vessels, and odontoblasts that comprise the innermost layer of a tooth. The pulp’s activity and signalling processes regulate its behaviour. Pulp.
What is the pulp stone?
Pulp stones are foci of calcification in the pulp of tooth. Calcification can occur in the dental pulp as discrete calcified stones or as diffuse form that can occur freely in the pulp tissue or is attached to or embedded into dentin [1.
What is pulp canal obliteration and how is it treated?
Pulp canal obliteration (also termed pulp chamber obliteration or root canal obliteration) is a condition which can occur in teeth where hard tissue is deposited along the internal walls of the root canal and fills most of the pulp system leaving it narrowed and restricted.
The exact causes of pulp obliteration are unclear but it typically occurs in response to dental trauma, especially following luxation injuries involving displacement, particularly if a tooth is replanted after being completely avulsed (knocked out) This response is common in this scenario and typically starts to occur several months after
What happened to the pulp chamber of a tooth?
It was possible to observe the complete obliteration of the pulp chamber, which was filled in part by reparative dentin and in part by a calcified tissue with a concentric layers structure with no tubular pattern. The root canals were almost completely obliterated by an amorphous calcified material.
