The instrument can help doctors obtain larger working space and visual field during the root canal treatment of posterior teeth and reduce the operation difficulty during the root canal treatment of the posterior teeth.

Description

technical field [0001] The invention relates to the technical field of oral medical instruments, in particular to a dental contra-angle handpiece and a root canal treatment instrument. Background technique [0002] Root canal therapy, also known as endodontics, is a procedure in dentistry to treat damaged tooth pulp and infected roots. Root canal therapy is the most effective treatment for acute pulpitis. By removing the necrotic tissue in the pulp cavity, and then refilling the pulp cavity after disinfection, the compression stimulation of the diseased tissue on the dental nerve is relieved to prevent further deterioration of the tooth condition. [0003] When performing root canal treatment, in order to reduce the treatment time and alleviate the patient's pain, it is usually necessary to perform root canal treatment with the help of a root canal treatment instrument. Among the root canal treatment instruments currently on the market, the dental contra-angle handpieces f...
