Wisdom tooth meets acute pulpitis, direct extraction or extraction after pulp opening?

Wisdom teeth are the remains of human evolution. Due to the degradation of the jaw, the eruption of wisdom teeth often causes ectopic eruption and impaction due to the lack of space. The abnormal eruption of and the difficulty of cleaning and prevention usually cause severe pain in the clinical manifestations of wisdom teeth pericoronitis, wisdom teeth or caries, periodontitis, pulpitis and other diseases near the teeth Therefore, surgeons generally recommend early prophylactic extraction of wisdom teeth with abnormal or asymmetric eruption The main clinical characteristics of acute pulpitis are...

Research progress of influencing factors on root surface damage after periodontal ultrasonic treatment

Plaque is the initial factor of periodontitis, and calculus is the most important local stimulation factor. periodontal basic treatment is the most basic treatment plan and measure for all patients with periodontitis. The purpose is to remove plaque, calculus and other plaque retention factors, eliminate inflammation, and reduce the damage of teeth and surrounding soft tissue as much as possible Periodontal ultrasonic therapy can not only remove dental surface sediment efficiently by high frequency oscillation force, but also has a unique effect on plaque clearance caused by cooling water and...

A case of primary tooth eruption disorder

A case of primary tooth eruption disorder

Tooth eruption is a process in which the crown moves toward the occlusal surface, involving the interaction of multiple factors (dental follicle, osteoclast and related signals, etc.), and the abnormality of one factor may cause the abnormal eruption of teeth In clinical practice, PFE is defined as partial tooth eruption disorder. There are no clear local or systemic factors in clinical practice, but the abnormal mechanism of tooth eruption is called primary tooth eruption disorder PFE is a rare disease, which is caused by the abnormal eruption mechanism of teeth....

A case report of foreign body swallowing during root canal therapy

As an effective method for the treatment of pulpitis and periapical periodontitis, 97% of the teeth can be retained in the mouth for about 8 years after treatment. However, the instruments required for root canal therapy are various, the steps are complex and time-consuming, and the rubber barrier is not widely used Once this kind of adverse event occurs, it will not only cause contradictions between doctors and patients, but also bring serious psychological problems to patients.
