Why do we need post after root canal treatment?

           There has been a misunderstanding that using posts can be very costly as they are difficult and complexed to make. Some are made from stainless steel or titanium. However, people start to use resin-based material to compose posts instead. The answer to whether posts are needed for endodontically treated teeth will be discussed in this essay. As recommended that, the practitioner should consider a few factors before making the decision.

           The most common reason that people place posts is to improve to reinforce the connection of the remaining tooth with the portion of the tooth. Although, this statement is accurate to the certain extent, there are other aspects that need to be considered. To start with, the we need to check the quantity of tooth structure remaining. The first condition is all coronal tooth structure exists except the endodontic hole, this condition does not need post. Because the resin-based part of the tooth usually bonded together and act as vital teeth. If more than one half of the coronal tooth structure present, this condition may not need posts as well. However, if the less than one half of coronal tooth is left, it is recommended to use posts to endure long term use of the teeth. The last condition is no tooth structure coronal is left, the remaining teeth should be extracted and put in the implants, which depends on the patient’s approval. However, there are two circumstances when there is no tooth structure left. The first one involves gingival tissue. In some incidents, we need to retain these teeth and plan for extrusion of the tooth orthondontically. Also, it is more advisable to extract the teeth and place implants. In the case where the practitioner aims to restore the teeth, the long-term consequences are still controversial. The second condition to no tooth structure is no tooth structure coronal to the bone. The best way is to extract the teeth but the patients need to be aware of the time and cost of the procedure.

           The second aspect to check is the quality of remaining tooth structure. Most of the time, we will find the following characteristics with the remaining tooth: cracks, demineralized, and other negative ones. Therefore, it is important to remove the tooth with negative characteristic enables us to assess the structure of the remaining tooth. After the removal process, the previously mentioned steps are to apply in using the posts.

           Next, we should also consider the remaining adjacent teeth. Having endodontically treated tooth with and without adjacent teeth lead to different outcomes. More occlusal forces are given to the tooth without adjacent teeth. To clarify, it is easier to use posts to restore the tooth when there is lesser surrounding teeth. Thus, using posts are recommended to make sure that the coronal tooth is adjusted with the root portion.

           Followed by the patient’s occlusion. Some patients have clenching habits that cause more stress on the teeth compared other patients. The movement of bruxers is from left to right and forward to back. By grinding, it creates massive stress on the teeth. If we come across the patients with this habit, it is recommended to use posts. The similar case happens with the endodontically treated tooth that plan to receive a single crown. With this tooth, it will have lower amount of stress if compared to fix prosthesis or removable partial denture. For this case, it is suggested that posts should be used.

           To summarize, in most cases, posts are necessary and often required for endodontically treated tooth. Several factors should be carefully checked before making the decision.
