The hardest tissue that covers the tooth structure's crown is enamel. Due to its high inorganic content (96 percent), it is considered the body's hardest substance. Most of the time, it has joined hydroxyapatite gems organized in a three-layered design, which gives it common tasteful and primary properties. However, constant and intricate changes in the oral microenvironment occasionally cause veneer demineralization, which in turn initiates caries. Caries of the teeth affects more than 66% of the population and is extremely common among individuals [3]. Numerous factors, including the presence of cariogenic microorganisms, dietary sugars, decreased salivary flow, and xerostomia, contribute to the onset of caries. In most cases, the processes of demineralization and remineralization in the oral cavity work in harmony. However, certain factors consistently tend to cause tooth demineralization, resulting in serious white spot sores, caries movement, and ultimately cavitation. The proper cleaning of the teeth to get rid of cariogenic bacteria, a healthy salivary stream, and the presence of enough calcium and phosphate particles in the spit can help control the restriction of tooth demineralization a little [4].
However, due to the fact that the body's normal defenses probably won't be enough to stop caries, minimally obtrusive dentistry techniques are typically used in a frantic effort to stop beginning caries and to protect as a significant part of the normal tooth design to maintain the tooth's utilitarian trustworthiness and style. By the way, finish recovery is still a difficult task, and it becomes even more difficult during clinical execution. As a result, it is essential to investigate alternative methods for lacquer fixation and specialized biomaterials that organically and primarily mimic the typical veneer. Pandya described four distinct approaches to polish tissue design and recovery: (a) physiochemical combination; (b) protein-grid directed enamel precious stone turn of events; (c) veneer surface remineralization; and (d) cell-based recovery. We will discuss these methods and the most recent advancements they have made in veneer mimetics [5].
