Active clinical trials for "Dental Enamel Hypoplasia"

Aim: To evaluate the clinical survival of fluoride sealants applied in first permanent molars affected by Molar-Incisor Hypomineralization (MIH). Material and Methods: For this case control study, it was selected 41 first permanent molars of the 21 children aged 6-8 years. MIH was classified by one calibrated examiner (kappa 0.80) according severity of the MIH lesion (EAPD, 2003). Inclusion criteria were FPM with MIH or sound (without MIH), fully erupted, and with sealant treatment indication. The FPMs were assigned into two groups: G1 - Control group and G2 - MIH group. Both group teeth were treated with sealant application (Fluroshield, NY, USA). Clinical follow-up was performed at baseline, 1, 6, 12 and 18 months for anatomic form, marginal adaptation, retention and presence of caries, according to the United States Public Health Service USPHS-Modified by a blinded examiner (kappa 0.80). The Acturial Method was used to evaluate the survival of sealants. Statistical analysis compared the ratings of each criterion between materials using the Fisher's exact test at a level of significance of 5% (p<0.05).

Vital pulp therapy (VPT) is a general term for multiple procedures (indirect pulp cap, direct pulp cap and pulpotomy) all directed toward preserving pulp vitality and enable complete root development in immature teeth. The aim of this study is to evaluate the clinical, radiographic and histologic (if any teeth later are doomed for extraction for orthodontic or other reasons) success rate of VPT on treating cariously exposed permanent teeth with developmental defects of enamel. This will be a a prospective case series study including children between 6-16 years old having tooth with enamel hypomineralization defect with deep caries, restorable teeth , and no signs of infection. The teeth will be followed up both clinically and radiographically for 1 year after treatment. It is expected that the teeth will maintain vitality with resolution of symptoms (if present) and completion of root development in immature teeth after vital pulp therapy.

the study evaluate the clinical outcome of zirconia versus lithium disilicate overlays restorations for restoring vital young permanent first molar teeth affected with moderate form of molar Incisor hypomineralization: randomized clinical trial.

It is a randomized clinical trial in which two different types of full coverage restoration in used to restore hypomineralized first permanent molar and protect the remaining tooth structure in patients with molar incisor hypomineralization ,one group is covered with CAD-CAM milled poly methyl methacrylate crowns and the other group is covered with cast metal copings (CAC) using nickel chromium alloy and there will be a nine months follow up.

Molar incisor hypomineralization (MIH) is a developmental defect of enamel affecting the first permanent molar and frequently the incisors with a prevalence of 16-16.9% in Malaysia. They presented with many problems such as hypersensitivity, increase susceptibility of caries, need for recurrent complex dental treatment, and difficulty to achieve pain control. Silver Diamine Fluoride is a new form of topical fluoride that has been extensively used and recommended for the management of caries in children and adolescents. The influence of organic material removal from artificial dentine lesions by means of surface pre-treatment with deproteinizing agent show favoring result of its use on subsequent remineralization with and without fluoride. The purpose of this trial is to study the clinical outcome of SDF and papain based gel on hypomineralized teeth restored with HVGIC.

The restorative management of molars with Molar-Incisor Hypomineralization (MIH) represents a challenge in the clinical practice with high failure rate. Thus, this clinical trial aimed to evaluate the clinical survival of direct composite resin restorations in first permanent molars (FPMs) that are affected by MIH, comparing two adhesive systems.

To compare responses to electrical pulp test (EPT) and cold test among molar incisor hypomineralization (MIH)-effected and not MIH-effected carious teeth before and after administration of local anesthesia for caries removal.

Background: Nowadays an increase in the incidence of teeth affected by molar incisor hypomineralisation (MIH) has been observed. There are several treatment modalities that depend on the degree of severity of the defect, such as preventive procedures, restorative and even dental extractions. However, these changes may affect the retention and longevity of restorative materials. Therefore, the aim of this study is to evaluate the use of diode laser irradiation for the treatment of occlusal surfaces of moderate lesions in permanent first molars affected with MIH as a preventive method for dental caries and occlusal wear, besides verifying the discomfort of the treatment by patients. Methods: For this, a controlled and randomized study, with parallel groups, will be conducted comparing the treatment with diode laser and sealing with high viscosity glass ionomer cement in the teeth affected by the MIH. Participants will be assessed at baseline and after 1 week, 1, 6, 12, 18 and 24 months. As the main outcome, the presence of dentin caries lesion and /or occlusal surface wear included in the study with dentin involvement will be evaluated. A visual examination for caries detection will be done using the ICDAS, using the index based on classification in the United States Public Health Service - Modified (USPH) for evaluation of sealed teeth and impression of impacted teeth for quantitative analysis of the lesions. Other outcomes such as patient satisfaction with treatment, patient discomfort, impact on quality of life and participant perception, as well as the duration and cost of treatment, as well as their cost-efficacy, will also be evaluated. Multilevel statistical analyzes will be performed to verify the efficacy of Diode laser treatment compared to sealing, in addition to possible factors associated with this efficacy.

Molar Incisor Hypomineralization (MIH) is a change in the formation of dental enamel of systemic origin that affects at least one of the first four permanent molars and usually affects incisors. During the eruption, the affected surfaces tend to fracture, exposing the dentin, which causes excessive sensitivity in addition to making the region very susceptible to the appearance of carious lesions. The objective of this research will be to evaluate the clinical effect of antimicrobial photodynamic therapy (aPDT) in permanent teeth with severe and sensitive MIH. The methodology will be based on the selection of patients from 6 to 12 years of age with permanent molar teeth, randomly divided in two groups. The selected teeth should have MIH on the occlusal surface, indicated for clinical restorative treatment. In Group 1, aPDT will be applied for the treatment of infected dentin. Afterwards, the teeth will be restored with high viscosity glass ionomer cement. In Group 2, the removal of the softened dentin around the side walls of the cavity with sharp dentine curettes and posterior restoration with high viscosity glass ionomer cement will be carried out. All patients will have clinical and radiographic follow-up with a time interval of 6 and 12 months. The data obtained will be submitted to descriptive statistical analysis to evaluate the association of categorical variables. Chi-square test and Fisher's Exact test will be used, and to analyze the correlation between the continuous variables, Pearson correlation test will be applied. For the analysis of dentin density in the scanned radiographic images and the microbiological results for colony forming units, ANOVA and Kruskal-Wallis will be applied.

The aim of this study is to compare the clinical outcome of using direct esthetic composite restorations in managing MIH cases and the use of preformed metal crowns.
