Problems solved by technology

However, due to problems such as radiation dose, resolution, and projection angle, the detection rate of cracks in clinical practice is not high, and there is no suitable method that can clearly display cracks without exposing patients to high radiation doses. Down

Abstract

The invention relates to the technical field of dentistry, in particular to a method for enabling a contrast agent to permeate into cracks of in-vitro subfissure teeth under vacuum assistance so as toachieve better development on CBCT. The method comprises the following steps: carrying out a subfissure tooth vacuum contrast agent adding experiment; shooting an enhanced small visual field CBCT; and collecting image data. According to the method, the liquidity and the X-ray radiation resistance of ioversol are utilized; the method comprises steps: placing ioversol liquid at the crown part of atooth crack; vacuumizing in a closed environment; after the ioversol contrast agent permeates into the structural cracks of the teeth, shooting CBCT as enhanced CBCT, comparing with a conventional CBCT before the crack permeation experiment, so that the detection rate of the CBCT on the fine crack of the tooth is increased, the invasion depth of the CBCT can be determined by measuring the high-density linear crack shadow, and the diagnosis capability of the CBCT on the subfissure of the tooth is improved.

Description

technical field [0001] The invention relates to the technical field of dentistry, in particular to a method for cracking cracked teeth with vacuum and contrast agent penetration. Background technique [0002] Cracked tooth is a common non-carious dental hard tissue disease, and it is the three major factors leading to adult tooth loss together with caries and periodontal disease. Cracked tooth refers to small, non-physiological, small cracks that occur on the surface of the crown, generally extending into the dentin, with different depths, and can extend beyond the marginal ridge. The shallow ones may be asymptomatic, and the deep ones It can be close to the pulp and even reach the pulp cavity. In patients with clinical symptoms of pulpitis, if no cause such as deep caries, wedge-shaped defects or deep periodontal pockets can be found, the existence of cracked teeth should be highly suspected. Cracked teeth are clinically difficult to diagnose due to inconspicuous early sy...
