Randomized Controlled Trial Comparative Study Clinical TrialEffects of psychological preparation on children hospitalized for dental operations.
We studied the effect of preoperative preparation on stress reduction in children hospitalized for dental surgery under general anesthesia. Participants were 45 children, 3 and 4 years of age, with no previous hospital-surgery experience and no history of medical or psychological conditions requiring special care. Subjects were randomly assigned to one of three experimental groups: control, receiving no preoperative preparation; unrelated play therapy, receiving a preoperative play session unrelated to hospital or surgical procedures; and related play therapy, receiving a preoperative play session focusing on hospital and surgical procedures. ⋯ The related play therapy group was more cooperative and less upset than either the unrelated play therapy group or the control group across stress points. No significant heart rate differences were found among the three groups. The results suggest that play therapy related to hospital and surgical procedures can alleviate stress and anxiety in 3- and 4-year-old children.

Comparative Study[Histomorphologic assessment of the effectiveness of anesthesia during tooth preparation].
The efficacy of conduction anesthesia with 2% solutions of novocain, celnovocain, trimecain, lidocain during the preparation of teeth for metal crowns was studied in experiments on 16 dogs by neurohistological and histochemical examination of the Gasserian and superior cervical ganglions, the nodose ganglion, teeth and pericoronal tissues. It was established that in terms of the degree of anesthesia efficacy increase, the test anesthetics can be arranged as follows: novocain, celnovocain, trimecain, lidocain.
