Abstract
ABSTRACT The objective of this study was to report the clinical treatment of a child with Incisor Molar Hipomineralization. A 5-year-old Brazilian child, male gender, was diagnosed with Molar Incisor Hypomineralization, reporting high teeth sensitivity. After anamnesis and clinical examination, treatment was conducted with three weekly applications of fluoride varnish containing 5% CPP-ACP complex. Also, it was advice to the patient for using a toothpaste containing fluoride and CPP-ACP (MI Paste Plus). After that, molars with great tooth structure loss were restored with resin modified glass ionomer cement. Prior to the first topical application of varnish with CPP-ACP and fluoride toothpaste containing CPP-ACP, a sensitivity test was conducted using thermal stimulus and facial pain scale. It was observed relative sensitivity decrease between sessions, reporting no sensitivity at the last session before the restoration. The treatment of Molar Incisor Hypomineralization teeth with CPP-ACP complex associated with fluoride varnish can be an alternative to reduce sensivity.
Highlights
Molar Incisor Hypomineralization (MIH) defines a situation comprising at least a hypomineralization of one or more first permanent molars and incisors, occured during amelogenisis, attributed to a systemic ethiology
Pneumonia, respiratory infections, otitis media, antibiotics, breast milk dioxin, tonsillitis and tonsillectomy, and rash fevers in childhood may be directly related to MIH [2]
Treatment by remineralization therapy is recommended as soon as an MIH defect is identified in order to increase mineralization and eliminate sensitivity [9]
Summary
Molar Incisor Hypomineralization (MIH) defines a situation comprising at least a hypomineralization of one or more first permanent molars and incisors, occured during amelogenisis, attributed to a systemic ethiology. Poor and reduced mineral content, high porosity, low hardness, defective microstructure, increased carbonate content, poor bonding properties, and pulpal changes associated with MIH can induce extreme sensitivity, increased caries lesion risk, and physical breakdown during normal function [7]. Because of these aspects, mainly the molars presenting MIH are more susceptible to plaque buildup and consequent greater risk for caries, having greater need for dental treatment [7]. Based on the above information on etiology, diagnosis, and treatment of MIH, the aim of this study was to report a case of severe MIH associated with a high teeth sensitivity and establish its treatment based on the literature, using dental materials containing CPP-ACP/ Fluoride varnish associated with toothpaste containing CPP-ACP/Fluoride and teeth restorations
