Demystifying behaviour and dental anxiety in schoolchildren during endodontic treatment for primary teeth-controlled clinical trial.

BACKGROUND

Behaviour and anxiety of children are predictors of effective dental treatment.

AIM

Compare the behaviour and anxiety during preventive care, endodontic treatment, and dental extraction.

DESIGN

Controlled clinical trial was conducted with 99 children aged 6-9 years. The children were distributed among three groups: G1 (control)-prophylaxis and topical fluoride; G2 (intervention)-endodontic treatment; and G3 (intervention)-tooth extraction. Behaviour was measured using the Frankl scale. Dental anxiety was assessed using the modified Venham Picture Test and measured at three moments: before, during, and after the procedure. Caregivers answered a questionnaire addressing the child's previous dental experience. Clinical examinations were performed by a calibrated examiner (Kappa > 0.70) for the identification of dental caries (d-dmft/D-DMFT). Statistical analysis involved repeated-measures Poisson regression, with level of significance was P < 0.05.

RESULTS

Neither negative behaviour nor anxiety was associated with the type of procedure. Negative behaviour was associated with the need for restraint during a previous dental appointment (P = 0.012). Dental anxiety was associated with age (P = 0.037), previous difficult behaviour (P < 0.001), moment of measurement (P < 0.001), and dental caries on permanent teeth (P = 0.001).

CONCLUSIONS

Negative behaviour and dental anxiety in children were not associated with the type of treatment performed.
