Abstract
ObjectivesThe 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.MethodsThirty-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.ResultsThe 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).ConclusionsSealing of hypersensitive MIH-affected molars revealed a significant improvement of OHRQoL immediately and throughout the 12-week follow-up.Clinical relevanceHypersensitivity can be a major complaint in patients with MIH. This is the first study evaluating the effect of sealing on OHRQoL in affected patients.
Highlights
Since its first introduction in 2001, there has been an increasing interest in molar incisor hypomineralization (MIH)
The criteria proposed by the European Academy of Paediatric Dentistry (EAPD) [15] were used for the diagnosis of MIH
One child was excluded because the follow-up Child Perceptions Questionnaire (CPQ) contained more missing items than allowed
Summary
Since its first introduction in 2001, there has been an increasing interest in molar incisor hypomineralization (MIH). The term is defined as enamel hypomineralization of systemic origin. Section for Outcomes Research, Medical University of Vienna, Spitalgasse 23, 1090 Vienna, Austria affecting one or more first permanent molars that are associated frequently with affected incisors [1]. MIH teeth can show rapid wear, enamel loss, increased susceptibility to caries, loss of fillings, and most of all, severe hypersensitivity often resulting in severe discomfort [3]. The underlying mechanism is not fully understood, but it is believed that the high porosity of the affected enamel favors the penetration of bacteria in the dentinal tubules, causing a subclinical pulpal inflammation [6]
