Abstract

ObjectivesThe aim of this study was to compare the efficacy in reducing hypersensitivity in molar incisor hypomineralization (MIH)-affected molars immediately and over 12 weeks after sealing using two different materials (composite and glass ionomer). Furthermore, the retention rates of both materials were analyzed.MethodsThirty-nine children with two MIH-affected molars showing hypersensitivity and non-occlusal breakdowns were included. Hypersensitivity was assessed with an evaporative (air) stimulus. Both teeth were sealed by two calibrated operators using a split-mouth design with either Clinpro Sealant in combination with Scotchbond Universal (C) or Ketac Universal (K), respectively. Clinical pain assessments (Schiff Score Air Sensitivity Scale [SCASS], Visual Analog Scale [VAS]) were made at baseline (“pre”), immediately after treatment (“post”), and after 1, 4, 8, and 12 weeks. Paired t tests were calculated in each group between baseline and all other time points.ResultsThirty-eight children with 76 molars completed all stages of the study. Regardless of the material used, the application of the sealant decreased hypersensitivity significantly immediately as well as throughout the 12-week recalls (all p values < 0.001). We found no statistically significant difference among both materials chosen in any of the time points evaluated. Furthermore, retention of both materials was comparable in both groups.ConclusionsBoth sealant materials were able to reduce hypersensitivity successfully immediately and throughout the 12-week follow-up. Furthermore, their performance was similar in terms of retention.Clinical relevanceHypersensitivity can be a major complaint in patients with MIH. This is the first study evaluating hypersensitivity relief of MIH-affected molars using two sealing techniques.

Highlights

Molar incisor hypomineralization (MIH) is defined as “demarcated, qualitative developmental defects of systemic origin of the enamel of one or more first permanent molars with or without the involvement of incisors” [1]
For the diagnosis of MIH, the criteria suggested by the European Academy of Paediatric Dentistry (EAPD) [22] were used
Discussion due to no complete agreement was necessary in some scores making the transition from “alfa” to “bravo.”. This is the first study evaluating the effect of a sealing on hypersensitivity treatment of MIH-affected molars worldwide

Summary

Introduction

Molar incisor hypomineralization (MIH) is defined as “demarcated, qualitative developmental defects of systemic origin of the enamel of one or more first permanent molars with or without the involvement of incisors” [1]. Recent data indicates that MIH is a frequently encountered dental condition worldwide [2]. MIH is considered to be an idiopathic condition, its concise etiology remains unclear [3]. Hypomineralized enamel can vary in color shade from white to yellow or brown [4], but always shows borders that are well-defined and distinct from sound enamel [5]. The condition could be associated with dental complications including rapid wear, enamel loss, increased susceptibility to caries, loss of fillings, and most of
