Good and thorough root canal cleaning is the key to treatment! Cleaning up the remaining marrow and removing the marrow is the most basic work. Although there are many mature root canal equipment technologies, it provides doctors with great work convenience. But there are still many people who have doubts about how to deal with the roots of the residual marrow and feel powerless. Today, Xiaoku will explain to you in detail how to deal with the problem of root marrow remnants painlessly under the existing equipment and technical conditions.
01 Method to improve drug inactivation
Perhaps many people will think that it is outdated to talk about drug inactivation and scorn. It must be acknowledged that there are huge regional differences in dental treatment in China, and the most common inactivating agents are still used in many counties and lower-level dental departments. Existence is the rationality of existence! Many people have reported that the widely used Shanghai Shipping Jia inactivation agent is not as effective as before. (The toxicity is reduced, the safety is improved, but the deactivation effect is not as good as before.) After two days of inactivation, it was okay to remove the top of the pulp and remove the crown. The patients were screaming from the root canal opening! Many doctors are distressed.
The editor disagrees with giving the patient a shot of anesthetic to remove the roots. I am also opposed to asking the patient to bear with it, and directly remove the marrow "with a cruel hand". Know that this will leave a big psychological shadow on the patient! In this regard, the editor has the following suggestions:
Two days after the application of the inactivating agent, remove the top of the pulp, remove the coronal pulp, and explore the root pulp pain when there is still vitality. Place a small cotton ball of inactivating agent smaller than the ball drill at the mouth of each root tube. If there are three root canals, three root canals that are not inactivated and fully viable, then three small cotton ball inactivating agents are sealed. If there are three root canals, two can be inactivated, and the dressing should be changed according to the normal root canal preparation, such as sealing CP cotton twist. If the remaining root canal is vigorous, a small cotton ball of inactivating medicine is sealed.
Many people worry that the root canal orifice is easy to move, so you can trim the root canal orifice with a G drill. You can dip a cotton ball of deactivator to CP infiltration and temporarily seal with slow-drying zinc oxide, which can reduce the pain of sealing. The inactivation method is suitable for patients who are more afraid of pain and have ample time for follow-up visits.
02Temporary sealing method of dry pulp paste liquid cotton twist
In clinical practice, many doctors like to use FC cotton to temporarily seal the residual pulp of the root canal. Many young doctors have poor control over the amount of FC, which can easily cause chemical irritation to the root tips. Use dry pulp paste liquid in practice (the main components are coal saponin and paraformaldehyde)
Twisting for temporary sealing is used to treat the root canal with residual marrow pain, which acts as a variant marrow and has better results.
The role of EDTA in the root canal is to soften the dentin and also as a lubricant. The main principle is that EDTA chelates with calcium ions in the dentin to form salt compounds, which have a soft texture. There is another function to emulsify the nerve tissue of the dental pulp to make it emulsify. It can also be used for paralysis (that is, pulp tissue can be removed under the action of EDTA in the case of residual pulp.)
Take a drop with the tip of tweezers like plasticization or use a smooth medullary needle to dip the beaded iodine liquid into the root canal, and use the iodine glycerin that contains a trace of iodine. Slightly cauterize and sterilize the root pulp to fix the root marrow. Use thinner No. 8, No. 10, and No. 15 H files for gentle expansion. After a while, rinse with hydrogen peroxide and physiological saline alternately to treat the residual marrow.
