Evaluation the effectiveness of chemomichanical caries removal compared with traditional technique in permanent molars affected with MIH
Abstract
Objective: Interest in chemomichanical dentin caries removal methods is increasing due to their effectiveness and the lower degree of pain associated with them, compared to traditional rotary methods. This study aimed to evaluate the effectiveness of removing dentinal caries by the chemomichanical method compared to the traditional method (rotating metal burs) on permanent molars affected by MIH in terms of the time required, the degree of pain associated with it, and the degree of patient satisfaction.
Materials and methods: The sample included (19) children (aged between 7-10 years) with positive cooperative behavior (according to Frankl) who had a diagnosis of MIH (molar incisor hypominiralization) on two permanent molars in the same patient with the presence of dentinal caries. The caries was removed from one molar using one of the two techniques and the other molar using the second technique. The time required to remove all of the dentinal caries was measured, then the associated pain was measured using the Wong & Baker scale. Patients’ satisfaction with the application of the two techniques and their desire to repeat it in the future when needed was also measured.
Results: The results showed that the average time required to remove caries chemomichanically (5.26 minutes) was more than three times greater than the average time required to remove caries using the traditional method (1.75 minutes). Also, the average value of the pain perception scale was statistically significantly greater in the traditional method (6.12) compared to the chemomichanical method (2.00), and patients’ satisfaction with the use of the chemomichanical method (84%) was statistically significantly greater than the traditional method that includes the use of rotating metal burs .
Conclusions: The chemomichanical caries removal method can help the doctor remove dentinal caries associated with MIH on permanent molars with the least possible pain and without the need for anesthesia in most cases, which resulted in a high rate of patient satisfaction and their desire to repeat the application of this method when need in the future. However, the time required to accomplish this may be several times longer than the traditional rotary method.
