Enamel infraction
Microcracks within the dental enamel of teethEnamel infraction, also known as craze lines, is a type of dental fracture that falls under the classification system based on the extent of tissue involvement and pulp exposure (Patnana and Kanchan, 2023). Dental fractures are categorized according to the affected tissue and whether the pulp is involved, with enamel infractions representing the least severe form, involving only microcracks contained within the enamel only without loss of tooth structure and are usually asymptomatic (Bonk, J., 2019). Enamel infractions are diagnosed by using transillumination and should be distinguished from cracks caused by thermal changes. Clinically, affected teeth typically show a normal response to pulp vitality tests, without mobility or periapical tissue involvement, and no sensitivity to percussion. Radiographic findings are usually unremarkable (Patnana and Kanchan, 2023).
