RESUMEN
<p><b>OBJECTIVE</b>To summarize the effect of oral midazolam sedation in a group of uncooperative patients in pediatric dentistry and analyze the influence of age on treatment results and safety.</p><p><b>METHODS</b>Oral midazolam conscious sedation (dosages range: 0.50 - 0.75 mg/kg) was applied to 109 uncooperative pediatric patients in outpatient department. The patients were divided into two age groups: group A (under 3 years) and group B (over 3 years). Treatment results and safety were statistically analyzed.</p><p><b>RESULTS</b>The mean success rate was 71% (77/109), which was higher in group B [78% (54/69)] than in group A [58% (23/40)]. The incidence of adverse reactions was 17% (19/109), which was higher in group A [28% (11/40)] than in group B [12% (8/69)].</p><p><b>CONCLUSIONS</b>Oral midazolam conscious sedation at a dosage range of 0.50 - 0.75 mg/kg is more effective and safe in pediatric dental patients over 3 years of age.</p>
