Does MIH Affects Preoperative and Intraoperative Hypersensitivity?

Abstract

Objective: Hypersensitivity is an important problem that is encountered during the treatment of hypomineralized teeth. The aim of this prospective study was to compare responses to electrical pulp tests (EPTs) and cold tests among carious teeth with and without molar incisor hypomineralization (MIH) before and after the administration of local anesthesia for caries removal Results: The EPT results of anesthetized carious teeth without MIH were significantly higher than those of carious teeth with MIH (p = 0.011). The cold test results were significantly higher for anesthetized carious teeth with MIH than for those without MIH (p = 0.0001). Intraoperative pain was significantly higher for carious teeth with MIH (p = 0.003). Conclusions: The results of this study suggest that even after achieving sufficient anesthesia, hypersensitivity remains a clinical problem in MIH-affected carious molars. The results presented in this study indicate that this phenomenon is not related to achieving effective local anesthesia; therefore, behavior management in such cases is of the utmost importance compared to relying on adjacent anesthetic methods.
