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.
Molar incisor hypomineralization (MIH) is one of the developmental enamel defect which is characterized by demarcated, qualitative defects of enamel of systemic origin affecting one to four first permanent molars (FPMs) and frequently associated with incisor involvement. Similar lesions can be seen in second primary molars and their presence has been reported as a predictive factor for developing MIH. Although the exact etiology of MIH is unclear, it is likely to be multi-factorial. Possible etiological factors of MIH are systemic conditions as pneumonia, upper respiratory tract infections, asthma, otitis media, hypoxia, high fever, hypocalcemia and exposure to antibiotics as amoxicillin. The prevalence of MIH has been reported from several studies to be between 2.8 and 40.2 %, with the mean approximately 15 %. MIH is considered as a common clinical problem by several epidemiological studies from many countries. Clinical presentation of MIH can include white, creamy and yellow-brown opacities, irregular areas of post eruptive breakdown, which can be mistaken diagnosed as hypoplasia or atypical caries. The condition is usually associated with a high disease burden, leading to pain, infection and tooth loss. Teeth affected by MIH are at high risk of rapid caries development and progression, rapid wear and enamel breakdown. Severely affected enamel disintegrates under masticatory forces resulting in post-eruptive breakdown (PEB), which is also a characteristic feature of MIH-affected teeth. These teeth require treatment, ranging from prevention to restorations and extractions, often under general anesthesia. A multidisciplinary cooperation among clinicians is often required, particularly for extractions of first permanent molars, when orthodontic consequences need to be considered. To evaluate the effect of this condition, questionnaires of dentists and dental professionals have been carried out in various countries, including those in Europe, Australia and New Zealand, Malaysia, Iraq, Iran and Saudi Arabian. These have generally revealed that MIH has been frequently encountered in clinical practice, particularly by dental professionals who treat children and that there is a need for further training for the condition. To date dental clinicians' concerns regarding MIH have not been extensively assessed in Egypt.
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.
The aim of this study is to assess the prevalence of molar incisor hypo mineralization among children who have been treated with asthmatic drugs during the first three years of life.
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.
