Occlusal force characteristics of masseteric muscles after intramuscular injection of botulinum toxin A(BTX - A)for treatment of temporomandibular disorder.

Our aim was to evaluate the occlusal force and therapeutic efficacy of the masseteric muscles after intramuscular injection of botulinum toxin A (BTX-A) for the treatment of patients with concurrent temporomandibular disorders (TMD) and bruxism. Thirty patients with TMD associated with bruxism were randomised into three groups (n=10 in each group), and treated by bilateral intramuscular injection of BTX-A into the masseter, placebo, or control. We used an occlusal force analysis system to collect several measures of occlusal force such as duration of biting and closing, the maximum occlusal force, and the distribution of occlusal force.

[Effect of health education pathway construction on outpatients with removal impacted teeth].

Purpose: To Introduce health education pathway to patients with removal impacted teeth, with the aim of helping patients to reduce tension or anxiety and improve the level of patients' satisfaction and cognition for dental surgery.

Methods: One hundred patients with impacted teeth surgery were randomly allocated into the experimental group and the control group. Health education pathway was given to patients in the experimental group while patients in the control group received traditional health education before surgery.
