Brief Summary:
Evaluation of oral midazolam to improve children's behavior and reduces the stress and anxiety during dental treatment

Condition or disease Intervention/treatment Phase
Early Childhood Caries Drug: Midazolam Drug: Placebo Phase 4

Detailed Description:

This study was initially planned to investigate three paediatric sedation regimens that also included the following arms:

  • oral midazolam + oral ketamine + inhaled sevoflurane
  • oral midazolam + oral ketamine + inhaled oxygen So, the former protocol found in the PRS registry was called PedSed-III and included the aforementioned arms.

However, there was a long delay in fund release from the funding agency (State of Goias Research Foundation - FAPEG). Although the grant was approved in the beginning of 2013, resources were released in November 2013.

We could not wait for funding release because this study was part of the MS dissertation of the principal investigator that was supposed to be concluded in the first semester of 2013. Then we decided to develop a less robust study, including only two arms: oral midazolam versus oral placebo. The other variables of the study did not change. We finished this two-arms study and have the final results for that comparison.

Drug: Midazolam
Dormire: Midazolam oral solution 2 mg/mL Sedative was administered with a syringe by the anaesthesiologist
Other Name: Brand: Dormire (Cristalia, Sao Paulo, Brazil)
Placebo Comparator: placebo
placebo oral syrup twenty minutes before starting the procedure

Primary Outcome Measures :
  1. child stress [ Time Frame: At child's awaking and arrival in the dental office, 25 min after local anesthetic administration, 25 min after dental session completion ]
    level of salivary cortisol according to the ELISA

Secondary Outcome Measures :
  1. Child behaviour [ Time Frame: every minute during the dental treatment up to the end of the dental session, which is estimated in 60 minutes ]
    child dental treatment is video recorded and then a masked observer watches the videos and categorize child behavior according to the Ohio State University Behavioral Rating Scale (OSUBRS)

  2. sedative safety [ Time Frame: during and twenty four hours after the procedure ]
    assessed according to the World SIVA adverse sedation event reporting tool
