A detailed inspection of the inner tooth morphology on röntgenogram is necessary as the surface morphology generally does not reveal the existence of an invagination. The irreversible pathological evolution occurring when diagnosis is neglected, should incite the practitioner to look for invaginations on every set of röntgenograms. Five therapeutic techniques are described. If an appropriate endodontic technique is applied, a successful root canal filling can be achieved.
由于表面形态通常无法显示内陷的存在，因此有必要在X线片上对牙齿内部形态进行详细检查。忽视诊断时发生的不可逆病理演变，应促使从业者在每一套X线片上寻找内陷。文中描述了五种治疗技术。如果应用适当的牙髓治疗技术，就能成功完成根管充填。
