Abstract
Background: Recently, tooth deformities have been frequently encountered by pediatric dentists. Severe enamel hypomineralization sometimes induces pain such as hyperesthesia, but composite resin restoration is difficult because it often detaches without any cavity preparation. Resin-based hypersensitivity inhibitors for tooth physically seal the dentinal tubules. It was reported that hypersensitivity inhibitor containing novel adhesive monomers forms apatite and induces remineralization in vitro. Therefore, these case series assessed the clinical effects of remineralization and the suppression of hypersensitivity by Bio Coat Ca (Sun Medical, Shiga, Japan). Methods: After mechanical tooth cleaning was performed, the hypersensitivity inhibitors were applied and cured by light exposure. Changes in hypersensitivity were determined by visual analog scale (VAS). The improvement of hypomineralization was evaluated by the change in color tone based on the digital images of intraoral photographs. Results: After repeated monthly treatments, these cases showed decreased hypersensitivity after the fourth application, while the opaque white and brownish color improved on the seventh application. Conclusion: This novel hypersensitivity inhibitor with calcium salt of 4-methacryloxyethyl trimellitic acid (C-MET) and 10-methacryloyloxydecyl dihydrogen calcium phosphate (MDCP) not only suppressed hypersensitivity but also improved cloudiness and brown spots in recently erupted permanent teeth in presented cases.
Highlights
Tooth deformities is a common disorder encountered by pediatric dentists
There is a continuity between hypomineralized second primary molars (HSPM) and molar incisor hypomineralization (MIH), and patients with HSPM are correlated with an approximately 20% risk of future MIH [10]
Fluoride varnish was previously used for the treatment of hypomineralization and hypersensitivity; the degree of elution varied depending on the product and there was no clear evidence of its efficiency
Summary
Tooth deformities (amelogenesis imperfecta, enamel dysplasia, enamel hypoplasia, and hypomineralization) is a common disorder encountered by pediatric dentists. Enamel hypoplasia is a firm enamel condition in which the tooth has pits, grooves, and thin enamel [4] If it occurs during the mineralization or maturation stage, it is called hypomineralization. In cases of primary tooth hypomineralization that are caused by systemic factors, pediatric dentists need to be careful about caring for future permanent teeth. The enamel of tooth deformities is opaque white in mild cases and brown or with defects in more severe cases. Subjective symptoms such as dentin hypersensitivity can occur. Case 1: Hypersensitivity of the Permanent Teeth with Brown and Cloudiness Spots Caused by Primary Tooth Trauma.
