Molar-Incisor Hypo mineralization (MIH) was first described in 2001 as a developmental enamel defect . It is a condition in which the enamel of at least one first primary molar is affected with a qualitative defect causing abnormal translucency appearing as demarcated opacities; The permanent incisors and second primary molars can also be affected . MIH has adverse consequences on the oral health and child's quality of life. It increases the risk of caries, discomfort and teeth sensitivity .
MIH management comprises a variety of treatment options ranging from total caries removal to the polar opposite treatment option of no caries removal and non-invasive methods used to prevent caries progression . Dental caries prediction and prevention are now more important than dental caries diagnosis and treatment. Recently, the reasons for repairing dental cavities have been narrowed, and caries prevention is being used to reduce caries . Salvadora persica, commonly known as Miswak was used as a toothbrush for many years among many countries . It was reported to have a significant effect on oral health and caries prevention .Other studies have found a consistent link between the use of Miswak and a reduction in oral bacteria. However, a comprehensive assessment of using Miswak in the treatment and control of MIH among young children has yet to be conducted.
Therefore, the aim of this clinical trial is to assess the effect of SalvadoraPersica and fluoridated toothpaste on controlling hypersensitivity and preventing caries among children with MIH in primary schools. Additionally, this trial will evaluate the shade of the hypo-mineralized enamel before and after using SalvadoraPersica and fluoridated toothpaste
