Changes in oral health-related quality of life after treatment of hypersensitive molar incisor hypomineralization–affected molars with a sealing

OBJECTIVES: The aim of this study was to investigate the changes in oral health-related quality of life (OHRQoL) before and after treatment of hypersensitive molars affected by molar incisor hypomineralization (MIH) with a sealing. METHODS: Thirty-eight children with two MIH-affected molars showing hypersensitivity and non-occlusal breakdowns were included. Hypersensitivity was assessed with an evaporative (air) stimulus. Two affected teeth were sealed by two calibrated operators using a split-mouth design: Clinpro Sealant in combination with Scotchbond Universal, and Ketac Universal (3M), respectively. OHRQoL was measured using the German version of the CPQ8–10 (CPQ-G8–10) at baseline, and after 1, 4, 8, and 12 weeks, respectively. RESULTS: The CPQ total score decreased significantly from a mean of 14.7 (±5.9) to 6.4 (±4.7) (p < 0.001) 1 week after treatment revealing improved OHRQoL. After 12 weeks, OHRQoL improved again proven by a decreased mean score of 2.7 (±3.2). CONCLUSIONS: Sealing of hypersensitive MIH-affected molars revealed a significant improvement of OHRQoL immediately and throughout the 12-week follow-up. CLINICAL RELEVANCE: Hypersensitivity can be a major complaint in patients with MIH. This is the first study evaluating the effect of sealing on OHRQoL in affected patients.
