Some important changes in the pulp cavity are: - Age: Secondary dentin formation makes it difficult to locate the chamber and canals. - Irritants: Lesions that expose dentin stimulate the formation of adjacent dentin. - Calcifications: Can be a normal process of maturation/aging or a response to irritations, appearing as pulp stones or diffuse calcifications. - Internal resorption: Uniform and bilateral loss of dentin that enlarges the pulp cavity. - Root dilaceration: Complex or severe root curvature, mostly in the buccolingual direction and difficult to see radiographically. - C-shaped: Occur in molars and due to complex anatomy, they can hinder endodontic treatment.
