Restorative Therapy of MIH-Affected Molars.

One fourth of teeth affected by molar incisor hypomineralisation (MIH) have required or will require treatment due to pain, sensitivity, or posteruptive breakdown. Restorative treatment becomes necessary in cases of severe MIH, characterized by posteruptive breakdown, which exhibits a wide range of clinical characteristics. Until approximately 20 years ago, all techniques, materials, and research were developed for treating caries lesions, not hypomineralisation.

What can impact on the presence of carious lesions in first permanent molars? Revisiting the association between MIH and caries.

Objective: Assess whether the independent variables (IV) such as number of MIH-affected molars, MIH severity, past caries experience, visible plaque index (VPI), gingival bleeding index (GBI), age, and gender affect the presence of caries lesion (DMF_s) in first permanent molars, considering or not atypical restoration in MIH-affected molars as a previous caries lesion.

Methods: A sample of 476 schoolchildren, aged 6-10 years, were evaluated for MIH and caries diagnosis, using the Severity Scoring System (MIH-SSS) and the International Caries Detection and Assessment System (ICDAS), respectively. From the ICDAS, the DF-s/ D-s and df-s were calculated.

Comparison between two molar incisor hypomineralization detection criteria in epidemiological surveys.

Background: There is no consensus on which molar incisor hypomineralization (MIH) indices are more suitable for epidemiological surveys.

Aim: To compare the operational aspects and diagnostic ability of the MIH index (simplified/MIH_s and extended/MIH_e) with the MIH-Severity Scoring System (MIH-SSS) in classifying and diagnosing MIH.

Design: This cross-sectional study assessed the indices in a homogeneous group of 680 6- to 10-year-old schoolchildren in Bauru, Brazil, who had at least one first permanent molar, ensuring consistent conditions.

Revisiting the use of stainless steel crowns for treatment of molar-incisor hypomineralization: a case series.

The restoration of teeth affected by molar-incisor hypomineralization (MIH) is challenging. To this end, preformed stainless steel crowns (SSCs) are a good option; however, their conventional use involves the removal of tooth structure. In the Hall technique, the SSC is seated over the primary teeth without caries removal or tooth preparation, aiming to seal carious lesions.

Vitamin E: A potential preventive approach against dental erosion-an in vitro short-term erosive study.

Objectives: This study evaluated the in vitro effect of different components of palm oil on enamel in a short-term erosive challenge.

Methods: The acquired enamel pellicle (AEP) was previously formed in situ for 2 h. Subsequently, the bovine enamel blocks were treated in vitro according to following solutions: G1-palm oil; G2-85% tocotrienol solution; G3-oily vitamin E; G4-oily vitamin A; G5-deionized water (negative control); G6-stannous-containing solution (Elmex® Erosion Protection Dental Rinse) (positive control).

Simplified occlusal replica adapted technique with glass ionomer cement for molar-incisor hypomineralization-affected molars: An 18-month follow-up.

Background And Overview: Molar-incisor hypomineralization (MIH) is a qualitative developmental defect of enamel, which has been a daily concern in clinical practice owing to its difficult treatment.

Case Description: An 11-year-old girl was admitted to the pediatric dental clinic with a symptom of severe hypersensitivity in the permanent molars owing to MIH. The treatment consisted of a simplified occlusal replica adapted technique with conventional glass ionomer cement in the MIH-affected molars, which involved laboratory and clinical stages.

Eroded enamel rehardening using two intraoral appliances designs in different times of salivary exposure.

Background: The aim of this study was evaluated the eroded enamel rehardening potential using upper palatal and lower buccal removable appliances in different times of salivary exposure (30 min, 1h, 2h, 12h) after a single erosive challenge event.

Material And Methods: After initial surface hardness evaluation, bovine enamel blocks were eroded in vitro (0.01 M hydrochloric acid, pH 2.

Influence of mandibular and palatal intraoral appliances on erosion in situ study outcome.

Objective: The standardization of in situ protocols for dental erosion is important to enable comparison between studies.Thus, the objectives of this study were to evaluate the influence of the location of in situ intraoral appliance (mandibular X palatal) on the extent of enamel loss induced by erosive challenges and to evaluate the comfort of the appliances.

Material And Methods: One hundred and sixty bovine enamel blocks were selected according to their initial surface hardness and randomly divided into two groups: GI - palatal appliance and GII - mandibular appliance.

Impact of a simplified in situ protocol on enamel loss after erosive challenge.

This study investigated the effect of the period of use and location of intraoral appliances on enamel surface loss. This randomized, single blind in situ study was conducted in 2 crossover phases based on the period of use, in which maxillary and mandibular appliances were simultaneously worn. Bovine enamel blocks (n = 120) were randomly divided among the studied groups by surface hardness.

In situ effect of enamel salivary exposure time and type of intraoral appliance before an erosive challenge.

Objectives: This study tested the effect of enamel salivary exposure time prior to an acid challenge (30 min, 1, 2, or 12 h) and type of intraoral appliance (palatal or mandibular) on initial erosion.

Methods: After initial surface hardness evaluation, enamel blocks (n = 340) were randomly divided into groups and volunteers (n = 20). The control group was not exposed to saliva previously to the erosive challenge.

Effect of different salivary exposure times on the rehardening of acid-softened enamel.

This in situ study assessed the effect of different times of salivary exposure on the rehardening of acid-softened enamel. Bovine enamel blocks were subjected in vitro to a short-term acidic exposure by immersion in 0.05 M (pH 2.

Resin infiltration of early carious lesion in early childhood: a case report.

The treatment of white-spot lesions in infants and young children with early childhood caries is a challenge. The ideal management of the disease and subsequent remineralization of the lesions depend on the family's commitment to dietary behavior modifications to address the causes of the disease. If this proves ineffective or unlikely, resin infiltration has been developed to slow or arrest progression of white-spot lesions.

In vitro assessment of artificial saliva formulations on initial enamel erosion remineralization.

Objectives: Various formulations of artificial saliva are present in the literature and little guidance is available on the standardization of type of saliva for use in in vitro protocols for erosive studies. The aim of this study was to evaluate the remineralizing capacity of different formulations of artificial saliva on initial enamel erosive lesion.

Methods: Bovine enamel blocks were subjected to short-term acidic exposure by immersion in citric acid 0.
