Filter by:A randomized clinical trial to compare silver modified glass ionomer restorations to non silver glass ionomer restorations in hypo-mineralized first permanent molars in children and to measure the amount of wear of restoration in both groups along with detecting changes in hypersensitivity in hypomineralized molars in both groups after one year follow up.
The objective of this research was to evaluate the clinical success of direct composite veneer restorations performed in permanent incisors affected by molar-incisor hypomineralization.
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.
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.
Molar incisor hypomineralization (MIH) can lead to many clinical conditions and affect oral health-related quality of life (OHRQoL).
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 135 children/molar teeth (N=45 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).
MIH is a prevalent developmental defect which has a negative impact on children's OHRQoL, especially when incisor opacities are present. The aim of this study is to evaluate the change in OHRQoL following minimally invasive aesthetic treatment of anterior permanent teeth opacities in children with MIH using the Arabic C-OHIP-SF19 as a data collection tool. This RCT will be conducted on children with MIH (n=156), aged 6-16 years, at the Post Graduate (PG) clinics, Jordan University of Science and Technology (Irbid). Patients will be randomly assigned in to two groups: Study group (n=78), with anterior teeth composite facing done to mask the opacity, and control group (n=78) where fluoride gel application was done. Children will be assessed by filling the COHIP-SF19 questionnaire before and one-month after the treatment to evaluate OHRQoL changes.
The aim of this study was to evaluate the efficacy of the association of casein phosphopeptide plus amorphous calcium phosphate (CPP-ACPF) mousse and photo-bio-modulation therapy (PMBT) (diode laser, RAFFAELLO 980 BIO - Dental Medical Technologies - DMT S.r.l.) in the treatment of dental hypersensitivity (DH) in children with Molar Incisor Hypomineralization (MIH) . Children aged 6-14 years with hypersensitive teeth were randomized into 3 groups. Group A received the application of CPP-ACPF mousse (GC MI Paste®) and sham light therapy; group B got the application of placebo mousse (Elmex Junior®) and PMBT; group C received both CPP-ACPF mousse and PMBT.
Enamel development defects are the result of a set of environmental, systemic and genetic causal agents that reveal a multifactorial etiology model, which in anterior teeth produces a serious aesthetic problem, converted into a problem of visual perception. In hypomineralized enamel, light rays encounter multiple interfaces between organic and mineral fluids, with different refractive indices. At each interface, the light is deflected and reflected, producing an overexposed "optical labyrinth" that is perceived as a yellow, white, or brown stain. The term "infiltration" has been modified and developed commercially in Germany for the treatment of non-cavitated caries on smooth and proximal surfaces, in which the porosities of the enamel lesion are infiltrated with a low-viscosity resin, thus creating a barrier of diffusion, without the need for any type of additional material on the tooth surface. An added positive effect of infiltration with the queens is that the enamel lesions lose their whitish appearance when the microporosities are filled, mimicking the area of the lesion with the remaining healthy enamel. This effect is what has led clinicians to adapt this treatment for the management of enamel defects. Given the growing interest in the treatment of opacities in the anterior sector, due to the demanding contemporary aesthetic requirements, and the increased acceptance of minimally invasive therapies, the need has been seen to seek greater predictability for the treatment of defects. of conservative enamel from an early age and offer effective therapeutic alternatives.
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
