Özet:

Tooth decay, which is one of the most common diseases in the world, can occur with symptoms such as pain and tenderness and can cause destruction of the tooth tissue, loss of chewing function and non-aesthetic appearance. Nowadays, with increasing caries rate, the incidence of deep dentin caries in deciduous and permanent teeth has increased. The term deep dentin caries; it is used in cases where there is a risk that the pulp may be exposed by removing the entire caries. It is emphasized that the treatments to be applied to these teeth should be as vital as possible. Thus, it is aimed to maintain the vitality of pulp tissue. Removal of the entire caries during deep caries treatment leads to pulpal perforations. The resulting pulp perforation negatively affects the long-term prognosis of the tooth. Therefore, the distinction between affected and infected dentin is important in terms of providing protective guidance in conservative treatment. In laboratory studies, the boundary between the infected dentin and the affected dentin can be distinguished visually, while in the clinic, dentists subjectively determine where this limit disappears and the amount of dentin to be removed. Therefore, there may be variations in the quality and amount of tissue removed by physicians. As a result, for an ideal treatment, all physicians should know the affected and infected dentin differentiation and clinical characteristics well and decide how much of it should be removed.
