Filter by:Restoration quality of molars affected by MIH using two different types of restorations direct composite and preformed crowns
The prevalence of molar incisor hypomineralization is relatively high. It has been reported that MIH-affected children experience a wide range of negative impacts because of having visible enamel opacities on their incisors whether these teeth show post eruptive breakdown or not. The management of MIH is challenging with a broad spectrum of treatment modalities being available. However, there are no clear guidelines available to aid in clinical decision making. Possible treatment options for anterior teeth with MIH include: Microabrasion, resin infiltration, tooth bleaching, etch-bleach and seal technique and composite restorations or veneers. It is believed that these methods could be used alone or in a combination of methods to achieve better aesthetic results. For MIH affected-incisors microabrasion and resin infiltration are acceptable treatment options which could be used alone or in a combination. Accordingly, the aim of this study is to compare the clinical outcomes of using resin infiltration either alone or combined with microabrasion for the management of MIH affected incisors.
Determining the Prevalence of Molar Incisor Hypomineralization Among a Group of Egyptian Children in Fayoum Governorate Schools via clinical examination. Participants from primary and preparatory schools in Fayoum governorate will be included in the study and Clinical examination will be carried out in the school laboratory or an empty class, in day light for both genders. Teeth will be cleaned gently using gauze and wet with saliva during examination. A disposable diagnostic set (mirror, probe) will be used for each patient where mirrors will be used for proper visualization especially for maxillary teeth. Blunt explorers will be used to aid in tactile sensation if needed, as during the differentiation between rough and smooth enamel edges and/or during the inspection of the caries extent if it exists. No diagnostic radiographs will be taken. The results of the study will be regularly monitored by the supervisors who will have full access to these results.
Assesment of the prevalence of molar incisor hypomineralization among a group of egyptian children aged from 8 to 12 years old in Damietta governate. This study will determine the severity of molar incisor hypomineralization which will help in its managment ,also will increase the awareness pf pediatric dentists about the prevalence of molar incisor hypomineralization in Egyptian children.Also it will allow the early detection of molar incisor hypomineralization which will make the parents seek early treatment for it. Participants fromprimary schools in Damietta governate will be included in the study. Clinica examination will be carried out in the school lab or in embty class, in day light.
Background: Dentin hypersensitivity (DH) is defined as high sensitivity of the vital dentin when exposed to thermal, chemical or tactile stimuli. Two mechanisms are required for the occurrence of DH: 1) the dentin must be exposed and 2) the dentinal tubules must be open and connected to the pulp. Molar-incisor hypomineralization (MIH) is a qualitative abnormality of a genetic origin that affects tooth enamel and, in most cases, is accompanied by DH. The control of tooth sensitivity is fundamental to the successful treatment of MIH. Objective: The aim of the proposed randomized, controlled, clinical trial is to evaluate the effectiveness of different protocols for the control of DH in patients with teeth affected by MIH. Methods: One hundred forty patients who meet the inclusion criteria will be allocated to four groups. Group 1 will be the control group (placebo). In Group 2, sensitive teeth will be sealed with Permaseal (Ultradent). In Group 3, sensitive teeth will receive low-level laser (LLL) (AsGaAl) at a wavelength of 780 nm (Laser XT Therapy, DMC, São Carlos, SP, Brazil). In Group 4, sensitive teeth will be treated with both LLL and Permaseal (Ultradent). DH will be evaluated 15 min after the application of the treatments and the patients will be reevaluated one week, one month, three months and six months after the treatments. Discussion: This study will enable the determination of differences in the effectiveness of the proposed treatments as well as differences among the evaluation times for each proposed treatment.
The aim of this study is to compare the clinical outcome of using direct esthetic composite restorations and the use of preformed metal crowns in managing MIH cases among a group of Egyptian children.
assessment of knowledge of dental interns regarding diagnosis of MIH among Group of interns in faculty of dentistry Cairo university
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 assess the prevalence of MIH among a group of Egyptian children aged from 8-12 years old in Dakahlia governorate schools.
