Abstract
Background: Cracked teeth (CT) are a potential issue in restorative dentistry as they can result in structure loss. A teeth crack is a deformation that displays as a break within the structure of teeth with no actual separation of the dental hard tissue. Posterior teeth (PT) cracks can be a source of pain and anxiety for the patient and the dental operator. Extension of the crack may lead to bone dehiscence. Nonetheless, the great focus is generally on cracks in teeth, with little focus on cracked PT.
Aim: To overview the cracks in PT.
Methods: The searching process was adopted to obtain related articles; this procedure involved using related terms, which were used in varied combinations through the search engine. The eligible research findings were all types of articles that reported PT cracks as the main title of the article or subtitle were eligible.
Results: The discussion was categorized into three major titles, with treatment titles including three subtitles to cover the subject as possible.
Conclusion: Cracks of the PT are frequent and relevant issues; however, there is an inaccurate determination of their incidence and prevalence. The risk factors of such cracks lack consensus as cracks are linked with multifactorial variations. The management of cracks can be hard due to the unknown extension of the crack and the late identification of the crack.

Key words: Incidence, Types, PT, Cracks, Risk factors.
