A few days ago, 33-year-old Ms. Jiang came to the Department of Stomatology of the Second People's Hospital of Hunan Province (Hunan Provincial Brain Hospital) for treatment, only to see her holding her right jaw with her hand on her face in pain, and Guo Lijing, the attending physician of the Department of Stomatology, received her.
It turned out that Ms. Jiang accidentally bit a stone when she was eating lunch, and when she bit down, she immediately felt a sharp pain, straight to the top of her head, and could not be relieved for 3 hours, and could only bite the gauze and paper towel to relieve the pain, and the tears flowed out. Dr. Guo examined it carefully and suspected that Ms. Jiang's teeth had cracked and may require further root canal treatment.
Immediately, Ms. Jiang took dental films in the department of stomatology. After reading the film, Dr. Guo analyzed that Ms. Jiang's teeth may have a root break, and further CT examination is still needed. After performing the three-dimensional CT reconstruction, Dr. Guo's judgment was clarified, and Dr. Guo gave the recommendation for tooth extraction.
Why does a small stone break a strong tooth? Dr. Guo introduced that because Ms. Jiang's affected teeth were originally hidden teeth, root folds occurred under the stimulation of external forces.
So what are cracked teeth? Resonates are small and difficult to find tooth cracks, congenital development and acquired external force damage can lead to the occurrence of fissures.
In recent years, due to age, wear, occlusal trauma, bad habits and other reasons, the incidence of fissured teeth has gradually increased, making it the third largest cause of adult posterior tooth loss after caries and periodontal disease, with an incidence of up to 70% in adults, most common in permanent molars, followed by premolars.
Residing teeth can cause a series of lesions in the tooth body, pulp, parietal and periodontal periodontal. Clinical manifestations are often cold irritation pain, occlusal pain, spontaneous pain, etc.
The clinical decision of resonates should be evaluated according to whether there is caries, the amount of remaining dental tissue, whether the fissure is visible to the naked eye, whether there are clinical symptoms, etc., and the prognosis of the resonatement tooth cannot be accurately judged, and the treatment methods such as blending, desensitization, observation, follow-up, crown repair or tooth extraction after root canal treatment can be used. Asymptomatic people should also be treated accordingly and repaired in time.
In addition, Dr. Guo further pointed out that dental problems are not small problems, when the crack is relatively shallow, there are no particularly obvious adverse symptoms, when the crack is deeper, involving dentin or through the dentin involving the vascular nerves will induce the occurrence of some adverse symptoms. At this time, you should actively seek medical treatment, and the cracks that are not treated in time will become more and more serious, and finally lead to the fracture of the tooth and cannot be retained.
Ms. Jiang is because she usually did not pay attention, in fact, her teeth have appeared hot and cold stimulation and spontaneous pain has appeared for 4 years, this slight external stimulation led to root folding, can not retain the affected teeth. Therefore, after ms. Jiang's tooth extraction, she still needs to carry out the next step of dental implant treatment in the future.
Dr. Guo once again reminded that when the teeth encounter hot and cold food with a strong sense of irritation, such as eating ice cream or eating hot pot, or when the hot and cold alternate, the teeth will feel obvious stinging, sour, and there is a fixed-point hidden pain or severe pain during the bite, and the hospital needs to seek medical treatment in time. Usually, it is more necessary to pay attention to prevention and avoid biting hard objects, especially bad habits such as opening beer bottles with teeth and biting walnuts must be quit.
