Active clinical trials for "Dental Enamel Hypoplasia"

This study tests the remineralization of donor teeth (donorMIH) in situ in participants using 10% hydroxyapatite (HAP) toothpaste and sodium fluoride toothpaste.

this clinical trial's aim is to compare two desensitizing agents available in the market to prove which one is more efficient in children with molar incisor hypomineralization complaining from hypersensitivity

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.

Aims: Comparison of injection pain with lidocaine and articaine in children with MIH . Comparison of the efficacy of lidocaine and articaine during treatment of MIH molars. Design: A randomized, controlled, crossover, double-blind clinical study including twenty cooperative children, aged 6-12years old

Difficulty in achieving anesthesia in teeth with molar incisor hypomineralisation (MIH) is a frequently reported clinical problem. The effect of low-level laser on the efficacy of anesthesia in teeth with MIH has not been studied yet. Aim of this study is to evaluate the effect of the Photobiomodulation on the efficacy of anesthesia of maxillary permanent molar teeth with MIH. Design: The current study was conducted as a prospective, parallel-arm control, randomized, triple-blind clinical trial in children aged between 7to12 years. Maxillary permanent molar teeth with MIH requiring pulpotomy treatment were included. 70 participants were divided randomly into 2 groups as experiment (with PBMT) and control (Placebo) according to the anesthesia technique. In the experimental group, before local infiltration anesthesia was administered, PBMT (a diode laser: 940 nm; continuous mode; 0.5W; 78 J/cm2) was applied perpendicular to the root surface at buccal and palatal area for 60 sec each). In the control group, the laser probe was directed to the mucosa for (buccal and palatal area), but not activated. Evaluation of the pain scores were performed during the access cavity preparation of the pulpotomy treatment using the Face, Legs, Activity, Cry, Consolability (FLACC) Scale. Also, additional anesthesia requirements were assessed for both groups while working on the dentin and pulp

The aim of this study is to evaluate the effectiveness of direct and Indirect Composite Restoration in Children With Molar Incisor Hypomineralization Patients (MIH) and following up after 3 , 6 , 12 months (Clinically): Group A ( Control group ): Hypomineralization molars were restored by direct composite. Group B ( Experimental group ): Hypomineralization molars were restored by indirect composite.

The aim of the following study is to evaluate che clinical efficacy of a toothpaste with biomimetic hydroxyapatite for the management of Molar-Incisor Hypomineralization. Patients who agree to participate to the study will use Biorepair toothpaste for the first 7 days of the month for 3, 6 and 9 months. The following indices will be measured: BEWE, Bleeding Index, Gingival index, Plaque index and the dental sensitivity test. The contralateral tooth will be used as control if not affected by MIH; otherwise, adjacent teeth will be considered.

Our aim is to mind the gap in research between the occurrence of MIH and its correlation with Stress and Anxiety.

This study will be performed to evaluate the clinical performance (Plaque accumulation, fracture of (restoration or tooth), postoperative sensitivity, secondary caries, marginal fit and discoloration) of two CAD/CAM fabricated ceramic restorations (zirconia-reinforced lithium silicate glass ceramic and hybrid ceramic) with different preparation designs (modified occlusal veneer and endocrown) for rehabilitation of permanent first molars affected with different severity level of molar incisor hypomineralisation (MIH), evaluated at different time periods

The investigators aimed to evaluate changes in mineralisation degree, colour, and size of the lesion after Icon® in permanent teeth with MIH in 6 months.
