Description
Technical Field
The utility model belongs to the oral medicine field, concretely relates to sting diagnosis inspection tool for examining hidden deciduous teeth for sting diagnosis inspection to hidden deciduous teeth.
Background
A creased tooth refers to a tooth having one or more occult cracks that begin at the crown and tend to extend toward the apex of the root. The anatomical shape of the tooth, the excessive occlusal force, the temperature effect, the iatrogenic factors and the like may be the pathogenic factors of the dental cryptorhagia (refer to blue Kelvin, duyu, the new development of the dental cryptorhagia research, diagnosis, treatment decision and prognosis evaluation, and the Chinese journal of oral medicine research (electronic edition) 2020, 14 (6), 339-343). Studies have shown that cryptocrackles are usually distributed in the proximal and distal directions, and can be located only in the occlusal surface and marginal crest of the crown, and can also extend to the adjacent surface or even under the gum, and the direction and depth of the fracture surface are usually difficult to predict. When a cryptofissure extends into an affected pulp cavity or subgingival apical region, it may lead to pulp and periapical lesions (see Yang SE, jo AR, lee HJ, et al. Analysis of the mechanics of crammed procedure and evaluation of pulp status recording to temporal binding depth [ J ]. BMC Oral Health,2017, 17 (1): 135. DOI.
Tooth cryptorrhea is the third most common cause of tooth loss, second only to caries and periodontal disease. Clinicians often face three major challenges associated with the subfissure of teeth — diagnosis, treatment decision making, and prognosis assessment. At present, the diagnosis of the cryptorrhexis is mainly based on clinical symptoms and cryptorrhexis exploration. For the affected teeth with suspected tooth cryptorrhoea symptoms, the clinician can gradually locate the affected teeth by a symptom representation method, i.e. a combined use of percussion, cold stimulation test, plastic wedge occlusion test, etc. (refer to Lubisich EB, hilton TJ, ferracane J. Cracked procedure: a review of the performance [ J ]. J estimate Restor Dent,2010, 22 (3): 158-167.DOI10.1111/j.1708-8240.2010.00330. X). For early stage of cryptorrhoea, patients often visit the clinic before complaining of pain in hard and tough foods, and for these patients, examination of the clinic is particularly important. The biting examination tool has no related registered products at home, and the biting examination can be carried out clinically through biting cotton swabs, rubber wheels and the like. There is a bite check tool abroad with the trade name of Tooth slope (Professional Results Inc), which is produced in the united states, and no dealer is found at home at present.
