The cracked tooth syndrome--crown root vertical fracture [PDF]

open access: yes, 1988
A case of an incomplete tooth fracture followed by a complete fracture was presented. The difficulty of diagnosing this condition was discussed as well as the possible histological explanation of the symptoms experienced by the patient.

Management of Cracked tooth syndrome: A case Report

open access: yesUpdate Dental College Journal, 2014
Cracked tooth is a distinct type of longitudinal tooth fracture which occurs very commonly and its diagnosis can be challenging. This type of fracture tends to grow and change over time. Clinical diagnosis is difficult because the signs and symptoms are

Cracked tooth syndrome [PDF]

open access: yes, 2021
Cracked tooth syndrome is defined as an incomplete fracture of the dentine in a vital posterior tooth that involves the dentine and occasionally extends into the pulp. CTS is the third leading cause of tooth loss in adult patients.

Fracture resistance of single-tooth implant-supported

open access: yes, 2014
The purpose of this study is to identify and compare the fracture behaviour of the ceramic used in a single-tooth implant-supported. This type of prosthesis is mainly used when a single tooth replacement is needed.

Research on a risk prediction model of gear tooth flank fracture based on multiaxial stress fatigue criterion

open access: yesJixie chuandong
ObjectiveTooth flank fracture is a contact fatigue failure mode of high-cycle/ultra-high-cycle fatigue damage where cracks initiate due to material damage at deep locations inside the tooth.
