The goal of this clinical trial is to examine the clinical success of different pre-treatments in resin infiltration therapy applied to the incisors of pediatric patients with Molar Incisor Hypomineralization (MIH) and to evaluate the impact of treatment on the quality of life of children. The main questions that this study aims to answer are: * Does resin infiltration therapy improve the color and surface appearance of incisors affected by MIH? * Is there a reduction in tooth sensitivity after treatment? * Are patients and their parents satisfied with the treatment results? * Is there an improvement in the quality of life of children after treatment? Researchers will apply resin infiltration therapy to incisors affected by MIH and evaluate the results over a 12-month follow-up period. Participants will: * Receive resin infiltration therapy on their MIH incisors. * Attend follow-up appointments at 1, 3, 6, 9, and 12 months. * At the follow-up appointments, the teeth will be evaluated with clinical examination and photographs. * Participants will complete questionnaires regarding tooth sensitivity and quality of life related to oral health. The results of this study are expected to contribute to the development of minimally invasive treatment options for children with MIH.

NCT07352813
This study aims to compare the effectiveness of intraosseous and infiltration anesthesia techniques administered using a computer-assisted anesthesia device (SleeperOne® 5; Dental HiTec, France) during restorative treatments of permanent first molars affected by Molar-Incisor Hypomineralization (MIH) in children. Clinical effectiveness will be evaluated based on the Visual Analogue Scale (VAS), behavioral pain response, pulse rate , salivary chromogranin A levels, and the need for additional anesthesia.
NCT07129720
This interventional, quasi experimental study aims to assess the effectiveness of an educational program on improving dental interns' knowledge, attitude and awareness regarding Molar-Incisor Hypo-mineralization (MIH). A total of 200 dental interns from Future University will participate. A structured questionnaire will be administered before and after the educational intervention to measure changes in participants' knowledge , attitude and awareness. The study seeks to evaluate whether targeted educational efforts can enhance clinical awareness and management approaches toward MIH among dental interns
NCT07049016
Molar Incisor Hypomineralization (MIH) is enamel hypomineralization defined as qualitative defects caused by disruptions in either the calcification or maturation phases of amelogenesis affecting one or more first permanent molars (FPMs) and permanent incisors.
NCT05809791
Molar and Incisor Hypomineralization (MIH) is a qualitative developmental defect of the dental enamel with a multifactorial aetiology defined in 2001 as an "hypomineralization of systemic origin affecting one or more permanent molars, usually first permanent molars (FPMs) with or without the involvement of one or more affected permanent incisors". Due to its porous structure with an altered prism organization and an increased content of proteins, the hypomineralized enamel has reduced mechanical properties and a lower refractive index in comparison to the sound enamel. MIH is associated to a large number of objective and subjective problems as an altered aesthetics, an increased risk of plaque accumulation, caries and/or post-eruptive breakdown, reduced retention rates of adhesive materials, hypersensitivity and difficulty in anesthetizing the affected teeth that make its management a challenging condition. MIH is a very widespread pathology with a worldwide prevalence ranging from 2.8 to 44% and a global average prevalence of 13.1% with significant geographical differences. In 2015, the number of global prevalent cases was estimated at 878 million people with a percentage of needing-care cases of 27.4% (in mean 240 million prevalent cases). In Europe, MIH prevalence rates between 3.6 to 25%. Regarding Italy, a limited number of prevalence studies are available. Recently, literature reports that the presence of MIH-like lesions in primary dentition, especially on second primary molars, may be a predictive factor for developing MIH in permanent dentition. However, the absence of this defect called Hypomineralized Second Primary Molars (HSPM) does not rule out MIH development. The early diagnosis of HSPM is very useful to early diagnose MIH and reduce its care burden. The reported HSPM global prevalence rate ranges from 0 to 21.8% with a global average about 7.88%. MIH and HSPM are both very widespread pathologies affecting an increasing number of children worldwide and represent a significant problem in pediatric dentistry. The aim of this study is to estimate the prevalence of MIH in Italian (Trieste), Spanish (Huesca, Zaragoza) and Turkish (Istanbul) children. The hypothesis is that the estimated prevalence of MIH may be in line with that reported in literature and that the presence of HSPM in primary dentition may be associated with MIH development in permanent dentition.
NCT05748067
In this prospective randomized clinical trial, the is aim to compare the clinical and radiographic success of 3 minimally invasive treatment protocols on permanent first molars affected with MIH over 24 months. A total of 73children/120molar teeth (N=40 molars per group) between the ages of 6-16 years with MIH will be recruited at the post-graduate clinics at Jordan University of Science and Technology (JUST).
NCT06426108
Molar incisor hypomineralization (MIH) manifests as a qualitative, demarcated defect in tooth enamel of systemic origin, predominantly affecting one or more permanent first molars, and potentially extending to the incisors. One significant challenge in managing this enamel anomaly is hypersensitivity, leading to discomfort and pain in affected patients. Low-intensity laser therapy, alone or combined with other modalities, appears promising in alleviating pain associated with MIH. This study aims to assess the efficacy of low-intensity laser therapy using varied parameters, in conjunction with a remineralizing agent, for pain management in children with molar incisor hypomineralization. Participants aged 6 to 12 years will be recruited, with a total of 88 teeth diagnosed with MIH, presenting a sensitivity score ≤3 on the Visual Analog Scale (VAS) and a score ≤1 on the Schiff Cold Air Sensitivity Scale (SCASS). The teeth will be randomly assigned to one of four groups (n=22 each): Group I (GI): L-1J + VF, Group II (GII): L-1J + VP, Group III (GIII): L-2J + VF, and Group IV (GIV): L-2J + VP. Here, 'L' denotes low-intensity laser application at different parameters (1J and 2J), combined with either fluoride varnish (VF) or a placebo varnish (VP). Interventions and assessments will be conducted initially, after 48 hours, and at 1 and 2 weeks post-treatment. Patients will undergo re-evaluation at 2, 4, 8, and 12 weeks following interventions. Statistical analyses will be performed with a 95% confidence level (α = 0.05).
NCT06348849
The aim of the current study is to assess the desensitising effect of nanosilver fluoride on first permanent molars (FPMs) in patients with MIH in comparison to low-level laser therapy.
NCT06801561
Background: Molar Incisor Hypomineralisation (MIH) is a qualitative defect of enamel that shows asymmetrical involvement of one to four permanent first molars (PFM) with or without incisor teeth involvement. MIH molars are prone to post-eruptive breakdown (PEB) and to the development of atypical caries lesions. Aim of the study: To evaluate and compare the preventive effect of glass ionomer sealant and laser therapy (LT) against dental caries and PEB on molars affected by molar incisor hypomineralisation (MIH) Materials and Method: This study is a two-arm, parallel group, randomized clinical trial. A sample of children (n=134) with an age range of 6-9 years old, having a first permanent molar erupted with MIH without PEB or carious lesion, will be selected from the outpatient clinic of Pediatric Dentistry and Public Health Department, Faculty of Dentistry, Alexandria University after securing necessary consents. All selected 134 first permanent molars will be randomly and equally allocated into two groups. Group 1(n=67): LT and Group 2 (n=67): Glass ionomer sealant (Fuji triage). Dental caries, PEB, retention of sealant and child-self-reported discomfort will be clinically evaluated after 6, 12 and 18months. Associations between dental caries and PEB with independent variables will be evaluated using logistic regression analysis (p \< 0.05).
NCT06776471
It is planned to include girls and boys between the ages of 6-12 who apply to Başkent University Faculty of Dentistry, Pediatric Dentistry Clinic for routine dental examination. Informed and written consent will be obtained from the parents of each participating child. In teeth planned to undergo treatment, molar ıncisor hypomineralization diagnosis will be made primarily in the presence of limited opacities/enamel fracture after eruption in at least one first permanent molar according to European Academy of Paediatric Dentistry criteria. In teeth diagnosed with molar ıncisor hypominerlization, tooth surfaces will be cleaned with a slow-speed rotary brush and dried with air before the evaluations to be made using the ICDAS II index. Early enamel caries lesions will be assessed by visual examination. The decayed, missing, filled teeth of the patients will be assessed according to the World Health Organization assessment criteria. The groups will be double-blind randomized as conventional fissure sealant (n=63) and self-adhesive flowable composite (n=63): Group I (acid+resin-based fissure sealant) will be etched with 37% phosphoric acid for 30 seconds, the surface will be rinsed and air dried until an opaque appearance is achieved on the enamel. Low-viscosity fluoride containing resin based fissure sealant will be applied to the etched enamel surface. Group II (self-adhesive flowable composite); self adhesive flowable composite will be applied in one step. All applied fissure sealants will be polymerized using a light device. Finally, occlusion control will be performed on fissure sealants with articulation paper.The Schiff Cold Air Sensitivity Scale will be used to assess the presence of hypersensitivity in the affected teeth by applying the air-water spray perpendicular to the occlusal surface of the tooth from a distance of 1 cm for 1 second. Clinical evaluation of fissure sealants will be performed at 1, 3, 6 and 12 months using modified . Sealants that receive "Alpha" or "Bravo" scores for all criteria (anatomical form, marginal adaptation, surface texture, marginal color change, retention and secondary caries) will be classified as successful; while "Charlie" scores received from one or more of the United States Public Health Service criteria will be evaluated as failure.
NCT06727539
The aim for thid study is to detect the prevalence of HSPM and the possible association between MIH and HSPM in a group of Egyptian children aged from 6-12 years. The study will also observe the possible etiological factors that might predispose hypomineralization of primary teeth. To our knowledge, there are no relevant studies that considered the prevalence of HSPM and its possible etiology in Egypt or its association with MIH. So, this study will address this knowledge gap. The possible relationship between HSPM and MIH is highly significant in pediatric dentistry, since the early diagnosis of HSPM as soon as second primary molars erupt makes it possible to initiate more intensive supervision and preventive measures, as these patients are otherwise prone to developing MIH in permanent teeth within a few years.
NCT06701552
We are conducting a study to understand how often MIH (Molar Incisor Hypomineralization) occurs and whether it is linked to a higher chance of dental cavities (caries). MIH is a condition where the enamel (the hard outer surface) of the first permanent molars and incisors (front teeth) doesn't develop properly, making these teeth more prone to damage and decay. We are looking at whether patients with MIH have more cavities in their teeth compared to patients without MIH. This study aims to help us learn more about the connection between MIH and dental health, so we can improve care and prevention strategies for kids at risk of cavities.
NCT06639815
Molar incisor hypomineralization has been defined as a qualitative developmental enamel defect affecting one or more permanent first molars, often including the permanent incisors. The development of the teeth with the developmental defect remains unclear. The aim of this study is to evaluate tooth development in children with MIH using the Cameriere and Haavikko methods on panoramic radiographs and to determine the accuracy of these methods. The first null hypothesis of this study was that there would be no difference in tooth development between children with MIH and children with healthy structure of teeth, and the second null hypothesis was that Cameriere and Haavikko methods could estimate dental age with the equal accuracy.
NCT06396988
The aim of the following study is to evaluate the clinical efficacy of a toothpaste with calcium and sodium phosphosilicate in the treatment of demineralization of the dental enamel of molars and incisors in pediatric patients. Patients who agree to participate to the study will use 2 different toothpaste Sensodyne Repair and Protect and Parodontax, which will used with split mouth design. The following indices will be measured: BEWE, Bleeding Index, Gingival Index, Plaque Index, Dental sensitivity test- Schiff, Pain Intensity Index- VAS and PPD.
NCT05806398
Molar Incisor Hypomineralization (MIH) is a worldwide widespread qualitative developmental defect of the dental enamel with a multifactorial aetiology defined in 2001 as an "hypomineralization of systemic origin affecting one or more permanent molars, usually first permanent molars (FPMs), with or without the involvement of one or more affected permanent incisors". Clinically MIH lesions appear as demarcated opacities with a creamy-white to yellow-brown colour depending on the severity of the defect that is classified as mild or severe (levels of severity) according to the European Academy of Pediatric Dentistry (EAPD) severity criteria. The distribution of the lesions is asymmetrical and their severity varies from a patient to another and also within the mouth of the same patient. Due to its porous structure with an altered prism organization and an increased content of proteins, the hypomineralized enamel has reduced mechanical properties and a lower refractive index if compared to the sound enamel. MIH is associated to a large number of objective and subjective problems as an altered aesthetics, an increased risk of plaque accumulation, caries, post-eruptive breakdown (PEB), reduced retention rates of adhesive materials, hypersensitivity and difficulty in anesthetizing the affected teeth making its management a challenging condition. Among preventive measures, pit-and-fissure sealants are a valuable and effective treatment to prevent occlusal caries in FPMs when they are still intact. However, since their efficacy is closely related to the sealant retention, they have to be monitored over time. When the molar to be sealed is fully erupted and isolation is adequate, resin-based sealants are indicated while if the moisture control is inadequate and/or the tooth is hypersensitive and patient is not sufficiently cooperative, low-viscous glass ionomer cements (GICs) are suggested as a temporary measure until the eruption is completed and both symptoms and cooperation are improved. To date, the scientific knowledge regarding the use of different type of sealants in MIH affected molars is insufficient to draw exhaustive conclusions and further studies are needed to deepen the knowledge on this topic. The aim of this study is to assess, by clinical examination, the survival rate of a glass ionomer sealant in MIH affected FPMs at 12 months of follow-up.
NCT05494749
Molar-incisor hypomineralization (MIH) is a qualitative enamel defect, in which molars and incisors involved are prone to post-eruptive enamel breakdown leading to sensitivity, and caries. Atraumatic/Alternative Restorative Treatment (ART) is a minimally invasive procedure. It can be very beneficial in managing MIH-affected molars in communities with limited access to dental care. Zirconia-reinforced GI was recently introduced. It is claimed to serve as a long-term temporary restoration until a more permanent restoration is placed
NCT04231019
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.
