Active clinical trials for "Dental Enamel Hypoplasia"

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 clinical outcome of using direct esthetic composite restorations in managing MIH cases and the use of preformed metal 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.

Restoration quality of molars affected by MIH using two different types of restorations direct composite and preformed crowns

The objective of this research was to evaluate the clinical success of giomer and resin-based sealants applied in the first permanent molars (FPMs) affected by MIH.

The purpose of this study is to evaluate and compare the clinical performance of Silver diamine Fluoride (SDF) and Silver diamine fluoride + Atraumatic resin restoration (SDF+ARR) on molars with MIH

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.

The main aim of this study is to investigate potential associations between maternal pre- and postnatal vitamin D level and oral health outcomes (caries and developmental defects of enamel) in their children at 7-9 years of age.

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.
