First, accurate preoperative assessment is essential. With the help of advanced oral imaging technology, such as cone beam CT (CBCT), the root canal morphology of deciduous teeth is comprehensively and meticulously analyzed in three-dimensional imaging. The complex features of the root canal, such as the degree of curvature, branching, length, and presence or absence of calcification, are clearly defined. For example, for deciduous teeth with severely curved root canals, the angle and path of the Platinum primary tooth file should be planned in advance to avoid unnecessary damage to the root canal wall during the operation. According to the evaluation results, the appropriate model and specification of Platinum primary tooth file should be selected to ensure that its flexibility and rigidity can adapt to the specific root canal morphology.
Secondly, the operation technique should be delicate and cautious. When entering the root canal, a gentle rotation and advancement method is used to allow the Platinum primary tooth file to slowly penetrate along the natural curvature of the root canal. Because the Platinum primary tooth file has good elasticity, it can conform to the curvature of the root canal to a certain extent, reducing the risk of file breakage. For root canals with branches, each branch should be explored patiently and step by step. A thinner file can be used for dredging first, and then a coarser file can be gradually replaced for expansion. During the expansion process, strictly control the amount of cutting each time, follow the principle of small amounts and multiple times, and prevent excessive cutting from causing thinning or perforation of the root canal wall. For example, when dealing with the bend of the root canal, you can use the technique of pulling up and down combined with a small rotation to ensure that the file needle cuts the root canal wall evenly and maintains the integrity of the root canal morphology.
In addition, combine with a suitable flushing scheme. During the process of using Platinum primary tooth file for root canal preparation, root canal flushing is performed simultaneously. Choose a mild and effective flushing solution, such as sodium hypochlorite solution, which can not only effectively dissolve necrotic tissue and bacteria, but also lubricate the root canal, which helps the smooth operation of Platinum primary tooth file. When flushing, a syringe with a fine needle can be used to inject the flushing solution into the bottom of the root canal, and its impact force can be used to bring the debris from the file out of the root canal to prevent the accumulation of debris from causing root canal blockage or infection spread. At the same time, according to the complexity of the root canal, reasonably adjust the frequency and pressure of flushing to ensure the maximum flushing effect.
Finally, close observation and evaluation after surgery. After completing the root canal treatment of the Platinum primary tooth file, we will use imaging examinations again to observe whether the root canal morphology meets the expected treatment standards, whether the root canal is clean, and whether there are any missed root canal branches or other abnormalities. If any problems are found, we will promptly perform additional treatment. In addition, we will closely monitor the child's postoperative reactions, including pain, swelling and other discomfort symptoms, so that appropriate treatment measures can be taken in time to ensure the effectiveness and safety of deciduous tooth treatment and lay a good foundation for the subsequent healthy development of deciduous teeth and the normal eruption of permanent teeth.
