This article reviews the diagnosis and treatment of cracked teeth, and explores
common clinical examples of cracked teeth, such as cusp fractures, fractures into
tooth furcations, and root fractures. This article provides alternative
definitions of terms such as cracked teeth, complete and incomplete fractures and
crack lines, and explores the scientific rationale for dental terminology
commonly used to describe cracked teeth, such as cracked tooth syndrome,
structural versus nonstructural cracks, and vertical, horizontal, and oblique
fractures. The article explains the advantages of high magnification loupes (×6-8
or greater), or the surgical operating microscope, combined with co-axial or
head-mounted illumination, when observing teeth for microscopic crack lines or
enamel craze lines. The article explores what biomechanical factors help to
facilitate the development of cracks in teeth, and under what circumstances a
full coverage crown may be indicated for preventing further propagation of a
fracture plane. Articles on cracked tooth phenomena were located via a PubMed
search using a variety of keywords, and via selective hand-searching of citations
contained within located articles.
